Description:
CODEBOOK-BASED OPERATION FOR SUBBAND FULL DUPLEX IN NR

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims priority to and the benefit of Greek Patent Application No.

20200100290, entitled, “CODEBOOK-BASED PUSCH OPERATION FOR SUBBAND FULL DUPLEX IN NR,” filed on May 29, 2020, (204929GR1) the disclosure of which is hereby incorporated by reference herein in its entirety as if fully set forth below and for all applicable purposes.

TECHNICAL FIELD

[0002] Aspects of the present disclosure relate generally to wireless communication systems, and more particularly, to sub-band full duplex operations. Certain embodiments of the technology discussed below can enable and provide codebook-based operations for sub-band full duplex operations (e.g., for uplink channels, such as a Physical Uplink Shared Channel (PUSCH)).

INTRODUCTION

[0003] Wireless communication networks are widely deployed to provide various communication services such as voice, video, packet data, messaging, broadcast, and the like. These wireless networks may be multiple-access networks capable of supporting multiple users by sharing the available network resources. Such networks, which are usually multiple access networks, support communications for multiple users by sharing the available network resources.

[0004] A wireless communication network may include a number of base stations or node Bs that can support communication for a number of user equipments (UEs). A UE may communicate with a base station via downlink and uplink. The downlink (or forward link) refers to the communication link from the base station to the UE, and the uplink (or reverse link) refers to the communication link from the UE to the base station.

[0005] A base station may transmit data and control information on the downlink to a UE and/or may receive data and control information on the uplink from the UE. On the downlink, a transmission from the base station may encounter interference due to transmissions from neighbor base stations or from other wireless radio frequency (RF) transmitters. On the uplink, a transmission from the UE may encounter interference from uplink transmissions of other UEs communicating with the neighbor base stations or from other wireless RF transmitters. This interference may degrade performance on both the downlink and uplink

[0006] As the demand for mobile broadband access continues to increase, the possibilities of interference and congested networks grows with more UEs accessing the long-range wireless communication networks and more short-range wireless systems being deployed in communities. Research and development continue to advance wireless technologies not only to meet the growing demand for mobile broadband access, but to advance and enhance the user experience with mobile communications.

[0053] The detailed description set forth below, in connection with the appended drawings, is intended as a description of various configurations and is not intended to limit the scope of the disclosure. Rather, the detailed description includes specific details for the purpose of providing a thorough understanding of the inventive subject matter. It will be apparent to those skilled in the art that these specific details are not required in every case and that, in some instances, well-known structures and components are shown in block diagram form for clarity of presentation.

[0054] The present disclosure is related to codebook-based schemes and operations for full- duplex wireless communications. In codebook-based operation, the reference signal that is transmitted is associated with a codebook. The present disclosure includes data channel- based operations, such as a sidelink and uplink operations, and can include different type of full-duplex wireless communication, such as sub-band full-duplex operations. Conventionally, sub-band full-duplex wireless communications specifications have a switching delay for switching an active bandwidth part (BWP). To illustrate, when switching from one a first BWP with a first frequency range to a second BWP with a second frequency range there is BWP switching delay period in which network bandwidth and spectrum are essentially wasted. Thus, network performance can be enhanced by improved usage of network bandwidth and spectrum by using a more flexible and quicker procedure.

[0055] According to some aspects, the present disclosure provides teachings that can enable and provide sub portions or units of a BWP. Such sub portions or units of a BWP may be referred to as resource bandwidths of the BWP, and also denoted as Resource BWs or RBWs. A BWP may include multiple UL, DL, or joint RBWs of varying sizes. Sub portions or units of a BWP, such as RBWs, offer more flexibility and granularity than BWPs, and by configuring / reconfiguring the sub portions or units of the BWP, the network spectrum can be adjusted more quickly, such as from slot to slot, i.e., without a delay. Thus, a BWP can changed and customized without the delay incurred of switching the BWP, i.e., switching the bandwidth or size of the BWP. Such techniques can improve usage of network bandwidth and spectrum, resulting in higher throughput and lower latency.

[0056] This disclosure relates generally to providing or participating in authorized shared access between two or more wireless devices in one or more wireless communications systems, also referred to as wireless communications networks. In various implementations, the techniques and apparatus may be used for wireless communication networks such as code division multiple access (CDMA) networks, time division multiple access (TDMA) networks, frequency division multiple access (FDMA) networks, orthogonal FDMA (OFDMA) networks, single-carrier FDMA (SC-FDMA) networks, LTE networks, GSM networks, 5 th Generation (5G) or new radio (NR) networks (sometimes referred to as “5G NR” networks/systems/devices), as well as other communications networks. As described herein, the terms “networks” and “systems” may be used interchangeably.

[0057] A CDMA network, for example, may implement a radio technology such as universal terrestrial radio access (UTRA), cdma2000, and the like. UTRA includes wideband-CDMA (W-CDMA) and low chip rate (LCR) CDMA2000 covers IS-2000, IS-95, and IS-856 standards.

[0058] A TDMA network may, for example implement a radio technology such as Global

System for Mobile Communication (GSM). The Third Generation Partnership Project (3GPP) defines standards for the GSM EDGE (enhanced data rates for GSM evolution) radio access network (RAN), also denoted as GERAN. GERAN is the radio component of GSM/EDGE, together with the network that joins the base stations (for example, the Ater and Abis interfaces) and the base station controllers (A interfaces, etc.). The radio access network represents a component of a GSM network, through which phone calls and packet data are routed from and to the public switched telephone network (PSTN) and Internet to and from subscriber handsets, also known as user terminals or user equipments (UEs). A mobile phone operator's network may comprise one or more GERANs, which may be coupled with Universal Terrestrial Radio Access Networks (UTRANs) in the case of a UMTS/GSM network. Additionally, an operator network may also include one or more LTE networks, and/or one or more other networks. The various different network types may use different radio access technologies (RATs) and radio access networks (RANs).

[0059] An OFDMA network may implement a radio technology such as evolved UTRA (E-

UTRA), IEEE 802.11, IEEE 802.16, IEEE 802.20, flash-OFDM and the like. UTRA, E- UTRA, and Global System for Mobile Communications (GSM) are part of universal mobile telecommunication system (UMTS). In particular, long term evolution (LTE) is a release of UMTS that uses E-UTRA. UTRA, E-UTRA, GSM, UMTS and LTE are described in documents provided from an organization named “3rd Generation Partnership Project” (3GPP), and cdma2000 is described in documents from an organization named “3rd Generation Partnership Project 2” (3GPP2). These various radio technologies and standards are known or are being developed. For example, the 3GPP is a collaboration between groups of telecommunications associations that aims to define a globally applicable third generation (3G) mobile phone specification. 3GPP long term evolution (LTE) is a 3GPP project which was aimed at improving the universal mobile telecommunications system (UMTS) mobile phone standard The 3GPP may define specifications for the next generation of mobile networks, mobile systems, and mobile devices. The present disclosure may describe certain aspects with reference to LTE, 4G, or 5G NR technologies; however, the description is not intended to be limited to a specific technology or application, and one or more aspects descried with reference to one technology may be understood to be applicable to another technology. Indeed, one or more aspects of the present disclosure are related to shared access to wireless spectrum between networks using different radio access technologies or radio air interfaces.

[0060] 5G networks contemplate diverse deployments, diverse spectrum, and diverse services and devices that may be implemented using an OFDM-based unified, air interface. To achieve these goals, further enhancements to LTE and LTE-A are considered in addition to development of the new radio technology for 5G NR networks. The 5G NR will be capable of scaling to provide coverage (1) to a massive Internet of things (IoTs) with an ultra- high density (e.g., ~1M nodes/km 2 ), ultra-low complexity (e.g., ~10s of bits/sec), ultra-low energy (e.g., -10+ years of battery life), and deep coverage with the capability to reach challenging locations; (2) including mission-critical control with strong security to safeguard sensitive personal, financial, or classified information, ultra-high reliability (e.g., -99.9999% reliability), ultra-low latency (e.g., - 1 millisecond (ms)), and users with wide ranges of mobility or lack thereof; and (3) with enhanced mobile broadband including extreme high capacity (e.g., - 10 Tbps/km 2 ), extreme data rates (e.g., multi-Gbps rate, 100+ Mbps user experienced rates), and deep awareness with advanced discovery and optimizations.

[0061] 5G NR devices, networks, and systems may be implemented to use optimized OFDM- based waveform features. These features may include scalable numerology and transmission time intervals (TTIs); a common, flexible framework to efficiently multiplex services and features with a dynamic, low-latency time division duplex (TDD)/frequency division duplex (FDD) design; and advanced wireless technologies, such as massive multiple input, multiple output (MIMO), robust millimeter wave (mmWave) transmissions, advanced channel coding, and device-centric mobility. Scalability of the numerology in 5G NR, with scaling of subcarrier spacing, may efficiently address operating diverse services across diverse spectrum and diverse deployments. For example, in various outdoor and macro coverage deployments of less than 3GHz FDD/TDD implementations, subcarrier spacing may occur with 15 kHz, for example over 1, 5, 10, 20 MHz, and the like bandwidth. For other various outdoor and small cell coverage deployments of TDD greater than 3 GHz, subcarrier spacing may occur with 30 kHz over 80/100 MHz bandwidth. For other various indoor wideband implementations, using a TDD over the unlicensed portion of the 5 GHz band, the subcarrier spacing may occur with 60 kHz over a 160 MHz bandwidth. Finally, for various deployments transmitting with mmWave components at a TDD of 28 GHz, subcarrier spacing may occur with 120 kHz over a 500MHz bandwidth.

[0062] The scalable numerology of 5G NR facilitates scalable TTI for diverse latency and quality of service (QoS) requirements. For example, shorter TTI may be used for low latency and high reliability, while longer TTI may be used for higher spectral efficiency. The efficient multiplexing of long and short TTIs to allow transmissions to start on symbol boundaries. 5G NR also contemplates a self-contained integrated subframe design with uplink/downlink scheduling information, data, and acknowledgement in the same subframe. The self-contained integrated subframe supports communications in unlicensed or contention-based shared spectrum, adaptive uplink/downlink that may be flexibly configured on a per-cell basis to dynamically switch between uplink and downlink to meet the current traffic needs.

[0063] For clarity, certain aspects of the apparatus and techniques may be described below with reference to example 5G NR implementations or in a 5G-centric way, and 5G terminology may be used as illustrative examples in portions of the description below; however, the description is not intended to be limited to 5G applications.

[0064] Moreover, it should be understood that, in operation, wireless communication networks adapted according to the concepts herein may operate with any combination of licensed or unlicensed spectrum depending on loading and availability. Accordingly, it will be apparent to a person having ordinary skill in the art that the systems, apparatus and methods described herein may be applied to other communications systems and applications than the particular examples provided.

[0065] While aspects and implementations are described in this application by illustration to some examples, those skilled in the art will understand that additional implementations and use cases may come about in many different arrangements and scenarios. Innovations described herein may be implemented across many differing platform types, devices, systems, shapes, sizes, packaging arrangements. For example, embodiments and/or uses may come about via integrated chip embodiments and/or other non-module-component based devices (e.g., end-user devices, vehicles, communication devices, computing devices, industrial equipment, retail/purchasing devices, medical devices, AI-enabled devices, etc.). While some examples may or may not be specifically directed to use cases or applications, a wide assortment of applicability of described innovations may occur. Implementations may range from chip-level or modular components to non-modular, non-chip-level implementations and further to aggregated, distributed, or OEM devices or systems incorporating one or more described aspects. In some practical settings, devices incorporating described aspects and features may also necessarily include additional components and features for implementation and practice of claimed and described embodiments. It is intended that innovations described herein may be practiced in a wide variety of implementations, including both large/small devices, chip-level components, multi- component systems (e.g. RF-chain, communication interface, processor), distributed arrangements, end-user devices, etc. of varying sizes, shapes, and constitution.

[0066] FIG. 1 is a block diagram illustrating details of an example wireless communication system. The wireless communication system may include wireless network 100. Wireless network 100 may, for example, include a 5G wireless network. As appreciated by those skilled in the art, components appearing in FIG. 1 are likely to have related counterparts in other network arrangements including, for example, cellular-style network arrangements and non-cellular-style-network arrangements (e.g., device to device or peer to peer or ad hoc network arrangements, etc.).

[0067] Wireless network 100 illustrated in FIG. 1 includes a number of base stations 105 and other network entities. A base station may be a station that communicates with the UEs and may also be referred to as an evolved node B (eNB), a next generation eNB (gNB), an access point, and the like. Each base station 105 may provide communication coverage for a particular geographic area. In 3GPP, the term “cell” can refer to this particular geographic coverage area of a base station and/or a base station subsystem serving the coverage area, depending on the context in which the term is used. In implementations of wireless network 100 herein, base stations 105 may be associated with a same operator or different operators (e.g., wireless network 100 may include a plurality of operator wireless networks). Additionally, in implementations of wireless network 100 herein, base station 105 may provide wireless communications using one or more of the same frequencies (e.g., one or more frequency bands in licensed spectrum, unlicensed spectrum, or a combination thereof) as a neighboring cell. In some examples, an individual base station 105 or UE 115 may be operated by more than one network operating entity. In some other examples, each base station 105 and UE 115 may be operated by a single network operating entity. [0068] A base station may provide communication coverage for a macro cell or a small cell, such as a pico cell or a femto cell, and/or other types of cell. A macro cell generally covers a relatively large geographic area (e g., several kilometers in radius) and may allow unrestricted access by UEs with service subscriptions with the network provider. A small cell, such as a pico cell, would generally cover a relatively smaller geographic area and may allow unrestricted access by UEs with service subscriptions with the network provider A small cell, such as a femto cell, would also generally cover a relatively small geographic area (e.g., a home) and, in addition to unrestricted access, may also provide restricted access by UEs having an association with the femto cell (e g., UEs in a closed subscriber group (CSG), UEs for users in the home, and the like). A base station for a macro cell may be referred to as a macro base station. A base station for a small cell may be referred to as a small cell base station, a pico base station, a femto base station or a home base station. In the example shown in FIG. 1, base stations 105d and 105e are regular macro base stations, while base stations 105a-105c are macro base stations enabled with one of 3 dimension (3D), full dimension (FD), or massive MIMO. Base stations 105a-105c take advantage of their higher dimension MIMO capabilities to exploit 3D beamforming in both elevation and azimuth beamforming to increase coverage and capacity. Base station 105f is a small cell base station which may be a home node or portable access point. A base station may support one or multiple (e.g., two, three, four, and the like) cells.

[0069] Wireless network 100 may support synchronous or asynchronous operation. For synchronous operation, the base stations may have similar frame timing, and transmissions from different base stations may be approximately aligned in time. For asynchronous operation, the base stations may have different frame timing, and transmissions from different base stations may not be aligned in time. In some scenarios, networks may be enabled or configured to handle dynamic switching between synchronous or asynchronous operations.

[0070] UEs 115 are dispersed throughout the wireless network 100, and each UE may be stationary or mobile. It should be appreciated that, although a mobile apparatus is commonly referred to as user equipment (UE) in standards and specifications promulgated by the 3 GPP, such apparatus may additionally or otherwise be referred to by those skilled in the art as a mobile station (MS), a subscriber station, a mobile unit, a subscriber unit, a wireless unit, a remote unit, a mobile device, a wireless device, a wireless communications device, a remote device, a mobile subscriber station, an access terminal (AT), a mobile terminal, a wireless terminal, a remote terminal, a handset, a terminal, a user agent, a mobile client, a client, a gaming device, an augmented reality device, vehicular component device/module, or some other suitable terminology. Within the present document, a “mobile” apparatus or UE need not necessarily have a capability to move, and may be stationary. Some non-limiting examples of a mobile apparatus, such as may include implementations of one or more of UEs 115, include a mobile, a cellular (cell) phone, a smart phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a laptop, a personal computer (PC), a notebook, a netbook, a smart book, a tablet, and a personal digital assistant (PDA) A mobile apparatus may additionally be an “Internet of things” (IoT) or “Internet of everything” (IoE) device such as an automotive or other transportation vehicle, a satellite radio, a global positioning system (GPS) device, a logistics controller, a drone, a multi-copter, a quad- copter, a smart energy or security device, a solar panel or solar array, municipal lighting, water, or other infrastructure; industrial automation and enterprise devices; consumer and wearable devices, such as eyewear, a wearable camera, a smart watch, a health or fitness tracker, a mammal implantable device, gesture tracking device, medical device, a digital audio player (e.g., MP3 player), a camera, a game console, etc.; and digital home or smart home devices such as a home audio, video, and multimedia device, an appliance, a sensor, a vending machine, intelligent lighting, a home security system, a smart meter, etc. In one aspect, a UE may be a device that includes a Universal Integrated Circuit Card (UICC). In another aspect, a UE may be a device that does not include a UICC. In some aspects, UEs that do not include UICCs may also be referred to as IoE devices. UEs 115a-l 15d of the implementation illustrated in FIG. 1 are examples of mobile smart phone-type devices accessing wireless network 100 A UE may also be a machine specifically configured for connected communication, including machine type communication (MTC), enhanced MTC (eMTC), narrowband IoT (NB-IoT) and the like. UEs 115e- 115k illustrated in FIG. 1 are examples of various machines configured for communication that access wireless network 100

[0071] A mobile apparatus, such as UEs 115, may be able to communicate with any type of the base stations, whether macro base stations, pico base stations, femto base stations, relays, and the like. In FIG. 1, a communication link (represented as a lightning bolt) indicates wireless transmissions between a UE and a serving base station, which is a base station designated to serve the UE on the downlink and/or uplink, or desired transmission between base stations, and backhaul transmissions between base stations. UEs may operate as base stations or other network nodes in some scenarios. Backhaul communication between base stations of wireless network 100 may occur using wired and/or wireless communication links. [0072] In operation at wireless network 100, base stations 105a-105c serve UEs 115a and

115b using 3D beamforming and coordinated spatial techniques, such as coordinated multipoint (CoMP) or multi-connectivity. Macro base station 105d performs backhaul communications with base stations 105a- 105c, as well as small cell, base station 105f Macro base station 105d also transmits multicast services which are subscribed to and received by UEs 115c and 115d. Such multicast services may include mobile television or stream video, or may include other services for providing community information, such as weather emergencies or alerts, such as Amber alerts or gray alerts.

[0073] Wireless network 100 of implementations supports mission critical communications with ultra-reliable and redundant links for mission critical devices, such UE 115e, which is a drone. Redundant communication links with UE 115e include from macro base stations 105d and 105e, as well as small cell base station 105f. Other machine type devices, such as UE 115f (thermometer), UE 115g (smart meter), and UE 115h (wearable device) may communicate through wireless network 100 either directly with base stations, such as small cell base station 105f, and macro base station 105e, or in multi-hop configurations by communicating with another user device which relays its information to the network, such as UE 115f communicating temperature measurement information to the smart meter, UE 115g, which is then reported to the network through small cell base station 105f. Wireless network 100 may also provide additional network efficiency through dynamic, low-latency TDD/FDD communications, such as in a vehicle-to-vehicle (V2V) mesh network between UEs 11 Si ll 5k communicating with macro base station 105e.

[0074] FIG. 2 shows a block diagram conceptually illustrating an example design of a base station 105 and a UE 115, which may be any of the base stations and one of the UEs in FIG. 1. For a restricted association scenario (as mentioned above), base station 105 may be small cell base station 105f in FIG. 1, and UE 115 may be UE 115c or 115D operating in a service area of base station 105f, which in order to access small cell base station 105f, would be included in a list of accessible UEs for small cell base station 105f. Base station 105 may also be a base station of some other type. As shown in FIG. 2, base station 105 may be equipped with antennas 234a through 234t, and UE 115 may be equipped with antennas 252a through 252r for facilitating wireless communications.

[0075] At base station 105, transmit processor 220 may receive data from data source 212 and control information from controller/processor 240. The control information may be for the physical broadcast channel (PBCH), physical control format indicator channel (PCFICH), physical hybrid-ARQ (automatic repeat request) indicator channel (PHICH), physical downlink control channel (PDCCH), enhanced physical downlink control channel (EPDCCH), MTC physical downlink control channel (MPDCCH), etc. The data may be for the PDSCH, etc. Additionally, transmit processor 220 may process (e g , encode and symbol map) the data and control information to obtain data symbols and control symbols, respectively. Transmit processor 220 may also generate reference symbols, e g., for the primary synchronization signal (PSS) and secondary synchronization signal (SSS), and cell- specific reference signal. Transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on the data symbols, the control symbols, and/or the reference symbols, if applicable, and may provide output symbol streams to modulators (MODs) 232a through 232t. For example, spatial processing performed on the data symbols, the control symbols, or the reference symbols may include precoding. Each modulator 232 may process a respective output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator 232 may additionally or alternatively process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. Downlink signals from modulators 232a through 232t may be transmitted via antennas 234a through 234t, respectively.

[0076] At UE 115, the antennas 252a through 252r may receive the downlink signals from base station 105 and may provide received signals to demodulators (DEMODs) 254a through 254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) a respective received signal to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM, etc.) to obtain received symbols. MIMO detector 256 may obtain received symbols from demodulators 254a through 254r, perform MIMO detection on the received symbols if applicable, and provide detected symbols. Receive processor 258 may process (e.g., demodulate, deinterleave, and decode) the detected symbols, provide decoded data for UE 115 to data sink 260, and provide decoded control information to controller/processor 280.

[0077] On the uplink, at UE 115, transmit processor 264 may receive and process data (e.g., for the physical uplink shared channel (PUSCH)) from data source 262 and control information (e.g., for the physical uplink control channel (PUCCH)) from controller/processor 280. Additionally, transmit processor 264 may also generate reference symbols for a reference signal. The symbols from transmit processor 264 may be precoded by TX MIMO processor 266 if applicable, further processed by modulators 254a through 254r (e.g., for SC-FDM, etc ), and transmitted to base station 105. At base station 105, the uplink signals from UE 115 may be received by antennas 234, processed by demodulators 232, detected by MEMO detector 236 if applicable, and further processed by receive processor 238 to obtain decoded data and control information sent by UE 115. Processor 238 may provide the decoded data to data sink 239 and the decoded control information to controller/processor 240.

[0078] Controllers/processors 240 and 280 may direct the operation at base station 105 and

UE 115, respectively. Controller/processor 240 and/or other processors and modules at base station 105 and/or controller/processor 280 and/or other processors and modules at UE 115 may perform or direct the execution of various processes for the techniques described herein, such as to perform or direct the execution illustrated in FIGS. 11 and 12, and/or other processes for the techniques described herein. Memories 242 and 282 may store data and program codes for base station 105 and UE 115, respectively. Scheduler 244 may schedule UEs for data transmission on the downlink and/or uplink.

[0079] Wireless communications systems operated by different network operating entities

(e.g., network operators) may share spectrum. In some instances, a network operating entity may be configured to use an entirety of a designated shared spectrum for at least a period of time before another network operating entity uses the entirety of the designated shared spectrum for a different period of time. Thus, in order to allow network operating entities use of the full designated shared spectrum, and in order to mitigate interfering communications between the different network operating entities, certain resources (e.g., time) may be partitioned and allocated to the different network operating entities for certain types of communication.

[0080] For example, a network operating entity may be allocated certain time resources reserved for exclusive communication by the network operating entity using the entirety of the shared spectrum. The network operating entity may also be allocated other time resources where the entity is given priority over other network operating entities to communicate using the shared spectrum. These time resources, prioritized for use by the network operating entity, may be utilized by other network operating entities on an opportunistic basis if the prioritized network operating entity does not utilize the resources. Additional time resources may be allocated for any network operator to use on an opportunistic basis.

[0081] Spectrum access control may be done in a variety of manners. In some deployments, for example, access to the shared spectrum and the arbitration of time resources among different network operating entities may be centrally controlled. Central control may be done by a separate entity (e.g., a scheduling entity, a base station, etc.). In some deployments, spectrum control may be autonomously determined by a predefined arbitration scheme. In still yet other arrangements or deployments (alternatively or additionally), spectrum control may be dynamically determined based on interactions between wireless nodes of the network operators.

[0082] In some cases, UE 115 and base station 105 may operate in a shared radio frequency spectrum band. Some shared bands may include licensed or unlicensed (e g., contention- based) frequency spectrum. In an unlicensed frequency portion of the shared radio frequency spectrum band, UEs 115 or base stations 105 may traditionally perform a medium-sensing procedure to contend for access to the frequency spectrum. For example, UE 115 or base station 105 may perform a listen-before-talk or listen-before-transmitting (LBT) procedure such as a clear channel assessment (CCA) prior to communicating in order to determine whether the shared channel is available. In some implementations, a CCA may include an energy detection procedure to determine whether there are any other active transmissions. For example, a device may infer that a change in a received signal strength indicator (RSSI) of a power meter indicates that a channel is occupied. Specifically, signal power that is concentrated in a certain bandwidth and exceeds a predetermined noise floor may indicate another wireless transmitter. A CCA also may include detection of specific sequences that indicate use of the channel. For example, another device may transmit a specific preamble prior to transmitting a data sequence. In some cases, an LBT procedure may include a wireless node adjusting its own backoff window based on the amount of energy detected on a channel and/or the acknowledge/negative-acknowledge (ACK/NACK) feedback for its own transmitted packets as a proxy for collisions.

[0083] FIGS. 3A, 3B, and 3C illustrate examples of full-duplex communication modes. In

FIG. 3A, full-duplex base station and half-duplex UE operations are shown, in FIG. 3B, full- duplex base station and full-duplex UE operations are shown, and in FIG. 3C, full-duplex UE operations with multiple TRPs are shown. Full-duplex operation corresponds to transmitting and/or receiving data via multiple antennas at the same time. Half-duplex operation corresponds to transmitting or receiving data via a single antenna at a particular time.

[0084] FIGS. 3A, 3B, and 3C depict interference caused from full-duplex operations. To illustrate, external interference and self-interference may be caused during full-duplex operations. External interference is caused from external sources, such as a from a nearby UE or base station. Self-interference is caused by the device. Self-interference may be caused by leakage, such as when transmitting energy from a transmitting antenna is received by receiving antenna directly or indirectly (e.g., by reflection). [0085] In FIGS. 3A, 3B, and 3C, multiple TRPs are illustrated, such as a first TRP (TRP1) and a second TRP (TRP2). The first and second TRPs may include or correspond to the same base station, such as the same gNB, or to different base stations. In FIGS. 3A, 3B, and 3C, the first TRP (TRP1) may be operating in the same frequency band or in different frequency bands. For example, the first TRP (TRPl) may be operating in a first frequency band, such as FR 4 or 60 GHz, and the second TRP (TRP2) may be operating in a second frequency band, such as FR 2 or 28 GHz.

[0086] Additionally, multiple UEs are illustrated in FIGS. 3A, 3B, and 3C, such as a first UE

(UE1) and a second UE (UE2) In some implementations, the UE is a full-duplex capable UE with multiple antenna module. FIGS. 3 A, 3B, and 3C further depict signal paths between the TRPs and the UES.

[0087] Referring to FIG. 3A, FIG. 3A illustrates an example diagram 300 for a first type of full-duplex communication. Referring to FIG. 3A, the diagram 300 illustrates two signal paths (beam paths) between the TRPs and the UEs and example interference. In the example illustrated in FIG. 3 A, the first TRP (TRPl) transmits downlink data via a first signal path to the first UE (UE1) and the first TRP (TRP2) receives uplink data via a second signal path from the second UE (UE2). The first TRP and UE experience interference. For example, the first TRP experiences self-interference from simultaneously transmitting and receiving. Additionally, devices receive interference caused by other nearby devices. For example, operations of the second TRP 2 may cause interference at all other nodes, such as the first UE and first TRP as illustrated in FIG. 3A. Additionally, the transmission of uplink data by the second UE may cause interference at the second TRP.

[0088] Referring to FIG. 3B, FIG. 3B illustrates an example diagram 310 for a second type of full-duplex communication. Referring to FIG. 3B, the diagram 310 illustrates two signal paths (beam paths) between the TRPs and the UEs and example interference. In the example illustrated in FIG. 3B, the first TRP (TRPl) transmits downlink data via a first signal path to the first UE (UE1) and the first TRP (TRPl) receives uplink data via a second signal path from the first UE (UE1). Additionally, the second TRP (TRP2) transmits downlink data via a third signal path to the second UE (UE2). The first TRP experiences interference. For example, the first TRP experiences self-interference from simultaneously transmitting and receiving and from the operations of the second TRP and UE. Additionally, other devices may receive interference caused by the operation other nearby devices, as described with reference to FIG. 3A. [0089] Referring to FIG. 3C, FIG. 3C illustrates an example diagram 320 for a third type of full-duplex communication. Referring to FIG. 3C, the diagram 320 illustrates three signal paths (beam paths) between the TRPs and the UEs and example interference. In the example illustrated in FIG. 3C, the first TRP (TRPl) receives uplink data via a first signal path from the first UE (UE1), and the first TRP (TRP2) transmits downlink data via a second signal path to the first UE and via a third signal path the second UE The first TRP may experience interference. For example, the first TRP experiences self-interference from simultaneously transmitting and receiving. Additionally, other devices may receive interference caused by the operation other nearby devices, as described with reference to FIG. 3A.

[0090] FIGS. 3D, 3E, and 3F illustrate examples of full-duplex communication operations.

In FIGS. 3D and 3F, in-band full-duplex (IBFD) operations are shown, and in FIG. 3E sub band full-duplex operations are shown. In-band full-duplex (IBFD) operation corresponds to transmitting and receiving on the same time and frequency resources. As showing in diagrams 330 and 340 of FIGS. 3D and 3E, the downlink and uplink resources share the same time and frequency resource. The downlink and uplink resources may fully or partially overlap, as shown in FIGS. 3D and 3E respectively. Sub-band full-duplex operation, often referred to as frequency division duplexing (FDD) or flexible duplex, corresponds to transmitting and receiving data at the same time but on different frequency resources. As shown in diagram 350 of FIG. 3F, the downlink resource is separate from the uplink resource by a relatively “thin” guard band. The guard band in FIG. 3F is enlarge for illustrative purposes. The guard band is what generally distinguishes SBFD from paired spectrum (e.g., IBFD) in current wireless standard specifications.

[0091] FIGS. 3G and 3H illustrate an example of BWP switching delay. FIG. 3G illustrates an BWP switching delay table and FIG. 3H illustrates a time delay in slots caused by switching a frequency / bandwidth of a DL BWP. Referring to FIG. 3G, a delay incurred in BWP switching is dependent on time and UE capability. To illustrate, the slot length (time in milliseconds) and type of the UE (Type 1 or Type 2) can be used to determine a delay in slots based on the table of FIG. 3G. The delay may also be dependent on sub-carrier spacing. As illustrated, if a Sub Carrier Spacing (SCS) is changed, the BWP switching delay is the larger of the two types of UE.

[0092] Referring to FIG. 3H, a first DL BWP (DL BWP1) is switched to a second DL BWP

(DL BWP2). In the example of FIG. 3H, the bandwidth / frequency range of the DL BWP is reduced. This switch causes a delay where no data is transmitted or received by the wireless communication device. As this example is for DL, no DL data is transmitted by the base station and no DL data is received by the UE. As the BWPs proposed herein include DL BWPs, UL BWPs, and joint BWPS (e g., DL/UL BWPs), both UEs and base stations may face switching delays and wasted transmit or receive opportunities Although the BWPs have described as uplink and downlink BWPs, the BWPs can be used for sidelink operations and support full-duplex operations in sidelink, that is simultaneous transmission and reception for sidelink communications.

[0093] FIG. 4 illustrates an example of a wireless communications system 400 that supports data-channel-codebook-based BWP changing in accordance with aspects of the present disclosure. Although the example of FIG. 4 will be described with respect to uplink operations, or PUSCH-channel-codebook-based BWP changing, the wireless communications system 400 also support sidelink operations, or PSSCH-channel-codebook- based BWP changing. In some examples, wireless communications system 400 may implement aspects of wireless communication system 100. For example, wireless communications system 400 may include UE 115 and network entity 405. PUSCH- codebook-based BWP changing operations may increase throughput and reliability by reducing interference (e.g., self-interference) and increasing throughput and reducing latency by reducing or eliminating BWP switching delay. Thus, network and device performance can be increased.

[0094] Network entity 405, UE 115, and optionally a second UE (e.g., another UE similar to

UE 115), may be configured to communicate via frequency bands, such as FR1 having a frequency of 410 to 7125 MHz, FR2 having a frequency of 24250 to 52600 MHz for mm- Wave, and/or one or more other frequency bands. It is noted that sub-carrier spacing (SCS) may be equal to 15, 30, 60, or 120 kHz for some data channels. Network entity 405 and UE 115 may be configured to communicate via one or more component carriers (CCs), such as representative first CC 481, second CC 482, third CC 483, and fourth CC 484. Although four CCs are shown, this is for illustration only, more or fewer than four CCs may be used. One or more CCs may be used to communicate control channel transmissions, data channel transmissions, and/or sidelink channel transmissions.

[0095] Such transmissions may include a Physical Downlink Control Channel (PDCCH), a

Physical Downlink Shared Channel (PDSCH), a Physical Uplink Control Channel (PUCCH), a Physical Uplink Shared Channel (PUSCH), a Physical Sidelink Control Channel (PSCCH), a Physical Sidelink Shared Channel (PSSCH), or a Physical Sidelink Feedback Channel (PSFCH). Such transmissions may be scheduled by aperiodic grants and/or periodic grants. [0096] Each periodic grant may have a corresponding configuration, such as configuration parameters/settings. The periodic grant configuration may include configured grant (CG) configurations and settings. Additionally, or alternatively, one or more periodic grants (e g., CGs thereof) may have or be assigned to a CC ID, such as intended CC ID.

[0097] Each CC may have a corresponding configuration, such as configuration parameters/settings. The configuration may include bandwidth, bandwidth part, HARQ process, TCI state, RS, control channel resources, data channel resources, or a combination thereof. Additionally, or alternatively, one or more CCs may have or be assigned to a Cell ID, a Bandwidth Part (BWP) ID, or both The Cell ID may include a unique cell ID for the CC, a virtual Cell ID, or a particular Cell ID of a particular CC of the plurality of CCs. Additionally, or alternatively, one or more CCs may have or be assigned to a HARQ ID. Each CC may also have corresponding management functionalities, such as, beam management, BWP switching functionality, or both. In some implementations, two or more CCs are quasi co-located, such that the CCs have the same beam and/or same symbol.

[0098] In some implementations, control information may be communicated via network entity 405 and UE 115. For example, the control information may be communicated suing MAC-CE transmissions, RRC transmissions, DCI, transmissions, another transmission, or a combination thereof.

[0099] UE 115 and second UE 405 can include a variety of components (e.g., structural, hardware components) used for carrying out one or more functions described herein. For example, these components can includes processor 402, memory 404, transmitter 410, receiver 412, encoder, 413, decoder 414, SBFD manager 415, RBW manager 416 and antennas 252a-r. Processor 402 may be configured to execute instructions stored at memory 404 to perform the operations described herein. In some implementations, processor 402 includes or corresponds to controller/processor 280, and memory 404 includes or corresponds to memory 282. Memory 404 may also be configured to store TPMI (transmit precoding matrix indicator) data 406, SRI (sounding resource signal (SRS) indicator) data 408, PUSCH codebook data 442, settings data 444, or a combination thereof, as further described herein.

[00100] The TPMI data 406 includes or corresponds to data associated with or corresponding to transmit precoding matrix indicator information. For example, the TPMI data 406 may indicate a particular precoding matrix to be used for uplink transmissions. Additionally, or alternatively, the memory 404 stores precoding information data. The data precoding information may be used to indicate a precoding matrix for transmission or reception. In some scenarios, the reference signal information may correspond to a particular RBW of a BWP. For example, the precoding information may indicate the RBW to use (e.g., which reference signal resource or data channel resource to use) for the reference signal and/or data channel transmission directly or indirectly. To illustrate, the precoding information may be used to determine a reference signal resource and a corresponding RBW by the RBW being configured for specific reference signals. As another illustration, the precoding information (e g., a precoding indicator) may be used with a look-up table or codebook to indicate the RBW and/or reference signal resource to use. In addition to or in the alternative of, the precoding information may similarly be used for data channel transmission RBW indication.

[00101] The SRI data 408 includes or corresponds to data indicating or corresponding to SRIs.

For example, the SRIs may indicate a particular SRS that was selected by the network entity, and thus a particular beam to use for uplink transmissions. In some implementations, the SRI may further indicate other uplink transmission parameters, such as rank. In the present disclosure, the TPMI and SRI data may be further used for PUSCH codebook operation and dynamic configuration of BWPs, such as RBWs thereof. Additionally, or alternatively, the memory 404 stores reference signal data, such as DMRS data. The reference signal data may indicate a particular reference signal, a reference signal indicator, a reference signal resource, or a combination thereof. In some scenarios, the reference signal information may correspond to a particular RBW of a BWP. For example, the reference signal information may indicate the RBW to use (e.g., which reference signal resource to use) for the reference signal, the data channel transmission, or both, directly or indirectly. To illustrate, the reference signal information may be used to determine a reference signal resource and corresponding RBW by the RBW being configured for specific reference signals. As another illustration, the reference signal information (e.g., a reference signal indicator) may be used with a look-up table or codebook to indicate the RBW and/or reference signal resource to use. In addition to or in the alternative of, the reference signal information may similarly be used for data channel transmission RBW indication.

[00102] The PUSCH codebook data 442 includes or corresponds to data that indicates a PUSCH codebook. The PUSCH codebook data 442 may be used to indicate a particular BWP configuration. In some scenarios, this can include a particular configuration of RBWs of a BWP. Additionally, or alternatively, the memory 404 stores data channel codebook data, such as PSSCH codebook data 442. The data channel codebook data 442 may be used to indicate a particular BWP configuration. In some scenarios, this can include a particular configuration of RBWs of a BWP. [00103] The settings data 444 includes or corresponds to data associated with SBFD PUSCH codebook operations. The settings data 444 may include one or more types of SBFD PUSCH codebook operations modes and/or thresholds or conditions for switching BWP configurations.

[00104] Transmitter 410 is configured to transmit data to one or more other devices, and receiver 412 is configured to receive data from one or more other devices. For example, transmitter 410 may transmit data, and receiver 412 may receive data, via a network, such as a wired network, a wireless network, or a combination thereof. For example, UE 115 may be configured to transmit and/or receive data via a direct device-to-device connection, a local area network (LAN), a wide area network (WAN), a modem-to-modem connection, the Internet, intranet, extranet, cable transmission system, cellular communication network, any combination of the above, or any other communications network now known or later developed within which permits two or more electronic devices to communicate. In some implementations, transmitter 410 and receiver 412 may be replaced with a transceiver. Additionally, or alternatively, transmitter 410, receiver, 412, or both may include or correspond to one or more components of UE 115 described with reference to FIG. 2.

[00105] Encoder 413 and decoder 414 may be configured to encode and decode data for transmission. SBFD manager 415 may be configured to determine and perform sub-band full duplex mode management and operations. For example, SBFD manager 415 is configured to control and coordinate SBFD operations. RBW manager 416 may be configured to determine to a particular RBW configuration. For example, RBW manager 416 is configured to determine and/or select a BWP and/or RBW configuration.

[00106] Network entity 405 includes processor 430, memory 432, transmitter 434, receiver 436, encoder 437, decoder 438, SBFD manager 439, RBW manager 440, and antennas 234a- t. Processor 430 may be configured to execute instructions stores at memory 432 to perform the operations described herein. In some implementations, processor 430 includes or corresponds to controller/processor 240, and memory 432 includes or corresponds to memory 242. Memory 432 may be configured to store TPMI data 406, SRI data 408, PUSCH codebook data 442, settings data 444, or a combination thereof, similar to the UE 115 and as further described herein.

[00107] Transmitter 434 is configured to transmit data to one or more other devices, and receiver 436 is configured to receive data from one or more other devices. For example, transmitter 434 may transmit data, and receiver 436 may receive data, via a network, such as a wired network, a wireless network, or a combination thereof. For example, network entity 405 may be configured to transmit and/or receive data via a direct device-to-device connection, a local area network (LAN), a wide area network (WAN), a modem-to-modem connection, the Internet, intranet, extranet, cable transmission system, cellular communication network, any combination of the above, or any other communications network now known or later developed within which permits two or more electronic devices to communicate. In some implementations, transmitter 434 and receiver 436 may be replaced with a transceiver. Additionally, or alternatively, transmitter 434, receiver, 436, or both may include or correspond to one or more components of network entity 405 described with reference to FIG. 2.

[00108] Encoder 437, and decoder 438 may include the same functionality as described with reference to encoder 413 and decoder 414, respectively. SBFD manager 439 may include similar functionality as described with reference to SBFD manager 415. RBW manager 440 may include similar functionality as described with reference to RBW manager 416.

[00109] During operation of wireless communications system 400, network entity 405 may determine that UE 115 has PUSCH-codebook-based BWP switching capability. For example, UE 115 may transmit a message 448 that includes a PUSCH codebook operation indicator 490 (e.g., dynamic RBW configuration indicator). Indicator 490 may indicate SBFD PUSCH codebook operation capability or a particular type or mode of SBFD PUSCH codebook operation. In some implementations, network entity 405 sends control information to indicate to UE 115 that SBFD PUSCH codebook operation and/or a particular type of SBFD PUSCH codebook operation is to be used. For example, in some implementations, message 448 (or another message, such as configuration transmission 450) is transmitted by the network entity 405. The configuration transmission 450 may include or indicate to use SBFD PUSCH codebook operation or to adjust or implement a setting of a particular type of SBFD PUSCH codebook operation.

[00110] During operation, devices of wireless communications system 400 can perform SBFD PUSCH codebook operations. For example, a network entity 405 may transmit an Uplink (UL) grant 452. The UL grant 452 may be a DCI or PDCCH transmission to UE 115 sent in a first slot. Optionally, a second network entity (e g., 405) may transmit a second UL grant (e.g., 452) to UE 115.

[00111] After receiving the UL grant (or grants) 452, the UE 115 may determine a TPMI and SRI indicated by the UL grant 452. For example, the UE 115 may determine the TPMI and the SRI based on TPMI and SRI indicators/bits in the UL grant 452. To illustrate, the UE 115 extracts TMPI data 406 from TPMI bits and SRI data 408 from SRI bits. As another illustration, the UE 115 extracts both the TMPI data 406 and SRI data from a single field or set of bits, such as an SRI field or TCI state field.

[00112] The UE 115 can determine a BWP configuration based on received information In some scenarios, the determination can be based on the TPMI data 406 and the SRI data 408 using the PUSCH codebook data 408. For example, the UE 115 may determine a particular BWP configuration and/or RBW configuration of the BWP based on using the TPMI and SRI indicated in the UL grant 452 and the PUSCH codebook. To illustrate, the UE 115 may determine a RBW for each of a SRS transmission 454 and a PUSCH transmission 456 to be sent by the UE 115 Example RBW configurations and additional details on BWP configuration determinations are described further with reference to FIGS. 5-9.

[00113] The network entity 405 (or entities) and UE 115 perform transmissions based on the BWP configuration indicated by the UL grant 452. For example, the UE 115 transmits the SRS transmission 454 in a particular RBW of the active BWP in a next slot (e.g., a second slot) after the UL grant 452 and the PUSCH transmission 456 in the particular RBW of the active BWP or in another RBW of the active BWP in a next slot (e.g., a third slot) after the SRS transmission 454. Thus, the UL grant 452 (e.g., DCI) and a PUSCH codebook (e.g., 442) may be used to indicate a RBW configuration for SRS and PUSCH transmission. Therefore, BWP configuration (e.g., BWP switching) may be performed slot to slot without incurring a slot delay. Accordingly, the UE 115 and network entity 405 (or entities) may be able to perform PUSCH-codebook-based RBW configurations.

[00114] Thus, FIG. 4 describes enhanced BWP configuration operations for full-duplex operations. Using PUSCH-codebook-based RBW configuration may enable improvement when operating in full-duplex modes. Performing PUSCH-codebook-based RBW configuration enables improved throughput and reduced latency and thus, enhanced UE and network performance.

[00115] Although the example of FIG. 4 demonstrates uplink data channel, or PUSCH-based, operations, the UE 115 may perform sidelink channel communications with another device, such as another UE. Such sidelink channel operations may include a sidelink grant in place of the uplink grant, a sidelink reference signal in place of the SRS (e.g., DMRS), a PSSCH in place of the PUSCH, or a combination thereof.

[00116] FIG. 5 is a timing diagram 500 of an example SBFD slot. In the timing diagram 500 of FIG. 5, time is the horizontal or x axis and frequency is the vertical or y axis. The timing diagram 500 illustrates two UL bandwidth sections on exterior edges of a CC/band and separated by DL bandwidth section in a middle / interior section of the CC/band. In each UL bandwidth section, there is a PUSCH transmission and a corresponding SRS resource (e.g., set of SRS resources).

[00117] FIG. 6-10 are diagrams of examples of an Active Bandwidth Part (BWP) illustrating resource bandwidths (RBWs) according to some embodiments of the present disclosure. Such RBWs (e.g., RBW configurations) are configurable by PUSCH codebook and UL grant indication as described in FIG. 4. In FIG. 6, an example BWP 600 layout is illustrated where frequency is the horizontal or x axis and time is the vertical or y axis. The BWP layout of FIG. 6 is an example BWP layout for the timing diagram of FIG. 5 and rotated 90 degrees. In FIG. 6, the BWP has four RBWs. The four RBWs may be allocated for UL or DL. In the example of FIG. 6, the four RBWs, RBW1-RBW4, are allocated for UL, and RBWl is a full bandwidth RBW, and RBW2-RBW4 are partial bandwidth RBWs. To illustrate, RBWl has the same bandwidth as the BWP and each of RBW2-RBW4 have less than the full bandwidth of the BWP. In the example shown in FIG. 6, RBW2 and RBW4 are contiguous partial bandwidth RBWs and RBW3 is a non-contiguous partial bandwidth RBW. A base station may dynamically and flexibly schedule SRS and PUSCH transmissions for such a configured BWP, as illustrated in FIGS. 7-10.

[00118] Referring to FIGS. 7-10, these figures illustrate various BWP and RBW arrangements. FIG. 7 is an example BWP 700 where the SRS and PUSCH transmissions are of the same RBW and overlap in frequency, FIG. 8 is an example BWP where the SRS and PUSCH transmissions are in different RBWs and have at least some overlap in frequency, FIG. 9 is an example BWP where the SRS and PUSCH transmissions are in different RBWs and do not overlap in frequency, and FIG. 10 is an example BWP where the SRS and PUSCH transmissions are of the same RBW but do not overlap in frequency. Each of these figures are further described below.

[00119] Referring to FIG. 7, each RBW (i.e. each of RBW1-RBW4) has one SRS transmission and one corresponding PUSCH transmission for the SRS transmission. Each of RBWl, RBW2, and RBW4 have full bandwidth SRS and PUSCH transmissions. RBW3 has a partial bandwidth SRS and corresponding partial bandwidth. To illustrate, the SRS and PUSCH transmissions only occupy one portion, i.e., a right side portion, of RBW3. In the example of FIG. 7, the RBWs are configured or set such that the SRS and PUSCH transmission have a full bandwidth overlap and are in the same RBW.

[00120] Referring to FIG. 8, the example BWP 800 illustrates two SRS transmissions and corresponding PUSCH transmissions. In the example of FIG. 8, the first RBW, RBWl, has a first full bandwidth SRS transmission, and the second RBW, RBW2, which is a partial bandwidth RBW, has a full bandwidth PUSCH. As illustrated in FIG. 8, because RBW2 is a partial bandwidth RBW, the PUSCH transmission overlaps a portion of the bandwidth of the SRS transmission. The third RBW, RBW3, has a second full bandwidth SRS transmission, and the fourth RBW, RBW4, which is a partial bandwidth RBW, has a partial bandwidth PUSCH. As illustrated in FIG. 8, because both RBW3 and RBW4 are partial bandwidth RBWs, the second PUSCH transmission overlaps an entirety of the bandwidth of the second SRS transmission. In the example of FIG. 8, the RBWs are configured or set such that the SRS and PUSCH transmission have a least a partial bandwidth overlap. However, unlike the example of FIG. 7, the SRS and corresponding PUSCH transmissions may be in different RBWs

[00121] Referring to FIG. 9, the example BWP 900 illustrates one SRS transmission and a corresponding PUSCH transmission. In the example of FIG. 9, the second RBW, RBW2, has a full bandwidth SRS transmission, and the fourth RBW, RBW4, which is a partial bandwidth RBW, has a full bandwidth PUSCH. As illustrated in FIG. 9, because both RBW2 and RBW are partial bandwidth RBWs, the PUSCH transmission does not overlap any portion of the bandwidth of the SRS transmission. In some implementations, the RBWs and SRS and PUSCH transmissions may not overlap to enable downlink transmissions, such as illustrated in FIG. 9. In the example of FIG. 9, the RBWs are configured or set such that the SRS and PUSCH transmission may have no association. To illustrate, the SRS and corresponding PUSCH may not be in the same RBW and may not even partially overlap, unlike the example of FIG. 8.

[00122] Referring to FIG. 10, the example BWP 100 illustrates one SRS transmission and a corresponding PUSCH transmission. In the example of FIG. 10, the third RBW, RBW3, has a SRS transmission in a first portion of the non-contiguous RBW, and has the corresponding PUSCH in a second portion of the non-contiguous RBW. As illustrated in FIG. 10, because both the SRS and PUSCH transmissions are in separate portions of the third RBW, RBW3, the PUSCH transmission does not overlap any portion of the bandwidth of the SRS transmission. In some implementations, the RBWs and SRS and PUSCH transmissions may not overlap to enable downlink transmissions to occur in the frequency between them, such as illustrated in FIG. 10. In the example of FIG. 10, the RBWs are configured or set such that the SRS and PUSCH transmission may have at least RBW association. To illustrate, the SRS and corresponding PUSCH may not even partially overlap, but they must be in the same RBW, unlike the example of FIG. 9. [00123] Although the SRS transmission and PUSCH transmissions in FIGS. 6-10 are illustrated in the same BWP diagrams for clarity and illustrative purposes, the actual SRS transmissions and PUSCH transmissions may occur in different slots. For example, a SRS transmission may occur in a prior or preceding slot to a corresponding PUSCH transmission, as illustrated in FIG. 4 by the SRS 454 and the PUSCH 456.

[00124] Additionally, although the BWPs have described as uplink and downlink BWPs, the BWPs can be used for sidelink operations and support full-duplex operations in sidelink, that is simultaneous transmission and reception for sidelink communications. To illustrate, the UL RBWs can be used for a sidelink transmission for a first device (e g., a first UE) and for a sidelink reception for a second device (e.g., a second UE). The DL RBWs can be used for a sidelink reception for the first device (e.g., the first UE) or a downlink reception for the first device. In some implementations, the DL RBWs can be used for a sidelink transmission by the second device (e.g., a second UE).

[00125] Particular devices may be set to operate according to one or more of the above BWP types of FIGS. 6-10 depending on hardware capabilities or may switch between the above BWP types of FIGS. 6-10 based on one or more conditions or inputs. Such different configurations, e.g., associations between SRS and PUSCH, may have different indications, different codebooks, or both.

[00126] As described with reference to FIG. 4, an UL grant (e.g., UL grant 452, such as DCI or SPS grant) includes SRI/TPMI information and PUSCH information such that the RBW configuration can be determined by the UE 115. In some implementations, the UL grant has a first configuration and can only provide indications where the SRI/TPMI is associated with an SRS resource that is defined within the same resource-BW (RBW) as that of the PUSCH, such as shown in FIG. 7. In such implementations, the UL grant may only have or indicate a RBW index / active BWP index of the PUSCH, and the SRI/TPMI may be used for the SRS resources defined for (e.g., within) that RBW index.

[00127] In some such implementations, the SRS resources within each RBW are configured separately. For example, RBWl having SRS0 and SRS1. RBW2 having SRS0 and SRS1. In some other such implementations, the SRS resources are configured across all RBWs. For example, RBWl having SRS0 and SRS1. RBW2 having SRS2 and SRS3. Thus, for both implementations, when you receive an indication that a PUSCH is to be transmitted in the ith RBW, then the SRS resources that can be used are those configured for the ith RBW.

[00128] In other implementations, the UL grant has a second configuration and may provide indications where the SRI/TPMI may contain or be associated with a separate index of a RBW index of an SRS resource or SRS resource set. In such implementations, the UL grant may include one RBW index for PUSCH resources and another RBW index for SRS resources (for the case of SRS resources locally defined within each RBW).

[00129] In some such implementations, the chosen SRS resource and the allocated PUSCH should have some overlap and/or association. For example, the SRS resource and the PUSCH have some at least a partial frequency-domain overlap. To illustrate, with respect to FIG. 5, a UL DCI cannot trigger a PUSCH in the lower subband that uses the upper subband as the SRS resource. Or, even if they are on the same subband with respect to the FD operation, they should have a PRB-level overlap. Such an example of a proper overlap is illustrated in FIG. 8. To illustrate, the SRS of RBWl partially overlaps with the PUSCH of RBW2, and the SRS of RBW3 partially overlaps with the PUSCH of RBW4.

[00130] As another example, the SRS resource and the PUSCH are part of the same active BWP even if the RBW is different. If the SRS resource and the PUSCH are in different RBWs of the same active BWP, the SRS resource and the PUSCH should be at least from the same subband of the FD operation (in the FIG. 5, either in the upper part or lower part). Such an example of a proper overlap is illustrated in FIG. 8. To illustrate, the SRS of RBWl partially overlaps with the PUSCH of RBW2, and the SRS of RBW3 partially overlaps with the PUSCH of RBW4.

[00131] In other such implementations, the chosen SRS resource and the allocated PUSCH do not have to overlap. For example the SRS resource and the allocated PUSCH can be in different subbands. In such implementations, the UE may report whether it supports SRS resource from one subband to be used for a PUSCH in another subband. For example, the UE may report it supports this generally, such as for all CC/bands. As another example, the UE may report such capability for each C C/band or on a per CC/band basis on whether it is possible to use the SRS from one subband to the next. Such an example of no overlap is illustrated in FIG. 9. To illustrate, the SRS of RBW2 does not overlap with the PUSCH of RBW4, and the SRS of RBW2 is separated from the PUSCH of RBW4 in frequency by a downlink portion and is not associated by RBW. Such an example of no overlap, or split subbands, is illustrated in FIG. 10. To illustrate, the SRS of RBW3 does not overlap with the PUSCH of RBW3, and the SRS of RBW3 is separated from the PUSCH of RBW3 in frequency by a downlink portion (e.g., a downlink resource). As compared to the example of FIG. 9, the SRS of RBW3 is associated with the PUSCH of RBW3 with respect to RBW, i.e., they are in the same RBW, RBW3. [00132] The preceding UL grant configurations are compatible with both: 1) SRS resources and PUSCH are configured per resource-BW of an active BWP; and 2) SRS resources are configured within an active BWP, and independent of a resource-BW configured for PUSCH. In such implementations, where the SRS resources and PUSCH are configured inside an active BWP. the BWP may include a “UL subband” (e.g., a consecutive chunk of PRBs) inside which a UE can transmit in the UL in a Subband Full Duplex operation.

[00133] If a separate RBW index / subband index for the SRS resource is included in the UL grant, the UL grant may be modified, as compared to a conventional UL grant. To illustrate, additional explicit indicator bits are added to the UL grant DCI to indicate the separate RBW index / subband index for the SRS resource. As another illustration, an SRS request field, which may be two (2) bits in some conventional implementations, may be increased so that each codepoint of the SRS request field can further indicate different SRS resource sets for different RBW index / subband index.

[00134] FIG. 11 is a flow diagram illustrating example blocks executed by a UE configured according to an aspect of the present disclosure. The example blocks will also be described with respect to UE 115 as illustrated in FIG. 13. FIG. 13 is a block diagram illustrating UE 115 configured according to one aspect of the present disclosure. UE 115 includes the structure, hardware, and components as illustrated for UE 115 of FIG. 2. For example, UE 115 includes controller/processor 280, which operates to execute logic or computer instructions stored in memory 282, as well as controlling the components of UE 115 that provide the features and functionality of UE 115. UE 115, under control of controller/processor 280, transmits and receives signals via wireless radios 1300a-r and antennas 252a-r. Wireless radios 1300a-r includes various components and hardware, as illustrated in FIG. 2 for UE 115, including modulator/demodulators 254a-r, MIMO detector 256, receive processor 258, transmit processor 264, and TX MIMO processor 266. As illustrated in the example of FIG. 13, memory 282 stores SBFD logic 1302, BWP logic 1303, RBW logic 1304, PUSCH codebook data 1305, TPMI data 1306, SRI data 1307, and settings data 1308.

[00135] At block 1100, a wireless communication device, such as a UE, receives an uplink grant indicating a PUSCH for a particular slot. The uplink grant can include precoding information, reference signal information and PUSCH resource information among other types of information. In a particular example, the uplink grant includes PUSCH resource information and at least one of the TMPI information or the SRI information. In some scenarios, additionally or alternatively, the UE 115 receives a DCI with one or more indices to indicate RBWs for a SRS and PUSCH, as described with reference to FIGS. 4-10.

[00136] At block 1101, the UE 115 transmits a reference signal, associated with the PUSCH, during a reference signal resource. The reference signal resource may be determined based on the PUSCH resource information or based on at least one of the precoding information or the reference signal information. In some scenarios, this reference signal is a SRS and the determination can be based on the PUSCH resource information or on one or more of the TPMI information or the SRI information. For example, in some deployments, the UE 115 determines a RBW of the active BWP for the SRS based on information of the DCI The determination or mapping of the SRS to the RBW can be based on RBW configuration (e.g., RBWl is configured for SRS0 and SRS1) or the RBW can be determined based on an index using an indicator in the DCI. Aspects of these features are described with reference to FIGS. 4-10.

[00137] At block 1102, the UE 115 transmits the PUSCH during the PUSCH resource of the particular slot. The PUSCH resource may be determined based on the PUSCH resource information and based on at least one of the precoding information or the reference signal information. In some scenarios, this reference signal is a SRS and the determination can be based on the PUSCH resource information and based on one or more of TPMI information or SRI information, as described with reference to FIGS. 4-10. For example, in some deployments, the UE 115 determines RBWs of the active BWP for the SRS and the PUSCH based on information of the DCI. The determination or mapping of the SRS and the PUSCH to the RBWs can be based on RBW configuration (e.g., RBWl is configured for SRS0 and SRS1) or the RBWs can be determined based on an index using an indicator in the DCI. Aspects of these features are described with reference to FIGS. 4-10.

[00138] In some scenarios, the UE operates in SBFD, that is transmits the PUSCH in the particular slot while also receiving a second transmission during the particular slot, as shown in FIG. 15. In some such SBFD operations or RBW-based BWP operations, the reference signal resource and the PUSCH resource correspond to RBWs of a BWP. For example, the UE 115 transmits a SRS transmission and a corresponding PUSCH transmission in the indicated RBWs of the BWP. Aspects of these features described with reference to FIGS. 4- 10

[00139] Although the example described in FIG. 11 is directed towards a UE operating in UL for a data channel, such as a PUSCH, the techniques described herein can be extended to other devices, directions, and/or channels. For example, the techniques described herein can be extended to network devices, sidelink communications, downlink communications, and/or control channel communications. To illustrate, a transmission which utilizes sub-portions (e g., RBWs) of a BWP may have its transmission resource (e g., which specific RBW of the BWP) indicated by transmission resource information and at least one of precoding information or reference signal information.

[00140] The UE 115 may execute additional blocks (or the UE 115 may be configured further perform additional operations) in other implementations. For example, the UE 115 may perform one or more operations described above. As another example, the UE 115 may perform one or more aspects as described below.

[00141] In a first aspect, the TPMI information, the SRI information, or both, are associated with an SRS resource of a same RBW as that of the PUSCH.

[00142] In a second aspect, alone or in combination with one or more of the above aspects, the PUSCH information indicates a RBW index of the PUSCH, and the TPMI information, the SRI information, or both, indicate the SRS resources defined within the indicated RBW index.

[00143] In a third aspect, alone or in combination with one or more of the above aspects, the SRS resources for each RBW are configured separately.

[00144] In a fourth aspect, alone or in combination with one or more of the above aspects, the SRS resources are configured across the RBWs.

[00145] In a fifth aspect, alone or in combination with one or more of the above aspects, the PUSCH information indicates a RBW index of the PUSCH, and the TPMI information, the SRI information, or both, are associated with a separate index of a RBW index of an SRS resource or SRS resource set.

[00146] In a sixth aspect, alone or in combination with one or more of the above aspects, the SRS resource and the PUSCH resource have at least a partial frequency-domain overlap.

[00147] In a seventh aspect, alone or in combination with one or more of the above aspects, the SRS resource and the PUSCH resource are part of the same active BWP.

[00148] In an eighth aspect, alone or in combination with one or more of the above aspects, the SRS resource and the PUSCH resource are part of different RBWs.

[00149] In a ninth aspect, alone or in combination with one or more of the above aspects, the SRS resource and the PUSCH resource are part of the same RBW.

[00150] In a tenth aspect, alone or in combination with one or more of the above aspects, the SRS resource and the PUSCH resource do not overlap. [00151] In an eleventh aspect, alone or in combination with one or more of the above aspects, the SRS resource and the PUSCH resource are in different subbands.

[00152] In a twelfth aspect, alone or in combination with one or more of the above aspects, the UE 115 transmits an indication of support for split subband SRS and PUSCH.

[00153] In a thirteenth aspect, alone or in combination with one or more of the above aspects, the indication identifies which CC or band supports split subband SRS and PUSCH.

[00154] In a fourteenth aspect, alone or in combination with one or more of the above aspects, the SRS resources and PUSCH are configured per RBW of an active BWP.

[00155] In a fifteenth aspect, alone or in combination with one or more of the above aspects, the SRS resources are configured within an active BWP, and independent of a RBW configured for the PUSCH.

[00156] In a sixteenth aspect, alone or in combination with one or more of the above aspects, the uplink grant includes one or more bits to indicate the RBW index subband index for the SRS resource.

[00157] In a seventeenth aspect, alone or in combination with one or more of the above aspects, the one or more bits are included in a SRS request field of the UL grant.

[00158] In an eighteenth aspect, alone or in combination with one or more of the above aspects, the slot prior to the particular slot is an immediately preceding slot.

[00159] In a nineteenth aspect, alone or in combination with one or more of the above aspects, the UE 115, prior to receiving the uplink grant, transmits a capabilities message indicating that the UE is configured for PUSCH-codebook-based BWP configuration.

[00160] In a twentieth aspect, alone or in combination with one or more of the above aspects, the UE 115, prior to receiving the uplink grant, receives a configuration message from a network entity indicating a PUSCH-codebook-based BWP configuration mode.

[00161] Accordingly, a UE and a base station may perform PUSCH-codebook-based BWP configuration operations. By performing PUSCH-codebook-based BWP configuration operations, throughput and reliability may be increased.

[00162] FIG. 12 is a flow diagram illustrating example blocks executed by wireless communication device configured according to another aspect of the present disclosure. The example blocks will also be described with respect to base station 105 (e g., gNB) as illustrated in FIG. 14. FIG. 14 is a block diagram illustrating base station 105 configured according to one aspect of the present disclosure. Base station 105 includes the structure, hardware, and components as illustrated for base station 105 of FIG. 2. For example, base station 105 includes controller/processor 240, which operates to execute logic or computer instructions stored in memory 242, as well as controlling the components of base station 105 that provide the features and functionality of base station 105. Base station 105, under control of controller/processor 240, transmits and receives signals via wireless radios 1401a-t and antennas 234a-t. Wireless radios 1401a-t includes various components and hardware, as illustrated in FIG. 2 for base station 105, including modulator/demodulators 232a-t, MIMO detector 236, receive processor 238, transmit processor 220, and TX MIMO processor 230. As illustrated in the example of FIG. 14, memory 242 stores SBFD logic 1402, BWP logic 1403, RBW logic 1404, PUSCH codebook data 1405, TPMI data 1406, SRI data 1407, and settings data 1408. One of more of 1402-1408 may include or correspond to one of 1302- 1308.

[00163] At block 1200, a wireless communication device, such as a base station 105, transmits an uplink grant indicating a PUSCH for a particular slot. The uplink grant can include precoding information, reference signal information, and PUSCH resource information among other types of information. In a particular example, the uplink grant includes PUSCH resource information and at least one of TMPI information or SRI information. In some scenarios, additionally or alternatively, the base station 105 receives a DCI with one or more indices to indicate RBWs for the PUSCH and its corresponding SRS, as described with reference to FIGS. 4-10.

[00164] At block 1201, the base station 105 receives a reference signal, associated with the PUSCH, during a reference signal resource. The reference signal resource may be determined based on the PUSCH resource information or based on at least one of the precoding information or the reference signal information. In some scenarios, this reference signal is a SRS and the determination can be based on the PUSCH resource information or on one or more of the TPMI information or the SRI information. For example, in some deployments, the base station 105 determines RBWs of the active BWP for the SRS and the PUSCH and indicates the RBWs based on information included in a DCI. Aspects of these features are described with reference to FIGS. 4-10.

[00165] At block 1202, the base station 105 receives the PUSCH during the PUSCH resource of the particular slot. The PUSCH resource may be determined based on the PUSCH resource information and based on at least one of the precoding information or the reference signal information. In some scenarios, this reference signal is a SRS and the determination can be based on the PUSCH resource information and based on one or more of the TPMI information or the SRI information, as described with reference to FIGS. 4-10. [00166] In some scenarios, the base station 105 operates in SBFD, that is transmits the PUSCH in the particular slot while also receiving a second transmission during the particular slot. In some such SBFD operations or RBW-based BWP operations, the reference signal resource and the PUSCH resource correspond to RBWs of a BWP. For example, the base station 105 receives a SRS transmission and a corresponding PUSCH transmission in the indicated RBWs of the BWP. Aspects of these features described with reference to FIGS. 4- 10

[00167] Although the example described in FIG. 12 is directed towards a base station operating in UL for a data channel, such as a PUSCH, the techniques described herein can be extended to other devices, directions, and/or channels. For example, the techniques described herein can be extended to UEs, sidelink communications, downlink communications, and/or control channel communications. To illustrate, a transmission which utilizes sub-portions (e.g., RBWs) of a BWP may have its transmission resource (e g., which specific RBW of the BWP) indicated by transmission resource information and at least one of precoding information or reference signal information.

[00168] The base station 105 may execute additional blocks (or the base station 105 may be configured further perform additional operations) in other implementations. For example, the base station 105 may perform one or more operations described above. As another example, the base station 105 may perform one or more aspects as described below.

[00169] In a first aspect, the TPMI information, the SRI information, or both, are associated with an SRS resource of a same RBW as that of the PUSCH.

[00170] In a second aspect, alone or in combination with one or more of the above aspects, the PUSCH information indicates a RBW index of the PUSCH, and the TPMI information, the SRI information, or both, indicate the SRS resources defined within the indicated RBW index

[00171] In a third aspect, alone or in combination with one or more of the above aspects, the SRS resources for each RBW are configured separately.

[00172] In a fourth aspect, alone or in combination with one or more of the above aspects, the SRS resources are configured across the RBWs.

[00173] In a fifth aspect, alone or in combination with one or more of the above aspects, the PUSCH information indicates a RBW index of the PUSCH, and the TPMI information, the SRI information, or both, are associated with a separate index of a RBW index of an SRS resource or SRS resource set.

[00174] In a sixth aspect, alone or in combination with one or more of the above aspects, the SRS resource and the PUSCH resource have at least a partial frequency-domain overlap. [00175] In a seventh aspect, alone or in combination with one or more of the above aspects, the SRS resource and the PUSCH resource are part of the same active BWP.

[00176] In an eighth aspect, alone or in combination with one or more of the above aspects, the SRS resource and the PUSCH resource are part of different RBWs.

[00177] In a ninth aspect, alone or in combination with one or more of the above aspects, the SRS resource and the PUSCH resource are part of the same RBW.

[00178] In a tenth aspect, alone or in combination with one or more of the above aspects, the SRS resource and the PUSCH resource do not overlap.

[00179] In an eleventh aspect, alone or in combination with one or more of the above aspects, the SRS resource and the PUSCH resource are in different subbands.

[00180] In a twelfth aspect, alone or in combination with one or more of the above aspects, the base station 105 receives an indication of support for split subband SRS and PUSCH.

[00181] In a thirteenth aspect, alone or in combination with one or more of the above aspects, the indication identifies which CC or band supports split subband SRS and PUSCH.

[00182] In a fourteenth aspect, alone or in combination with one or more of the above aspects, the SRS resources and PUSCH are configured per RBW of an active BWP.

[00183] In a fifteenth aspect, alone or in combination with one or more of the above aspects, the SRS resources are configured within an active BWP, and independent of a RBW configured for the PUSCH.

[00184] In a sixteenth aspect, alone or in combination with one or more of the above aspects, the uplink grant includes one or more bits to indicate the RBW index subband index for the SRS resource.

[00185] In a seventeenth aspect, alone or in combination with one or more of the above aspects, the one or more bits are included in a SRS request field of the UL grant.

[00186] In an eighteenth aspect, alone or in combination with one or more of the above aspects, the slot prior to the particular slot is an immediately preceding slot.

[00187] In a nineteenth aspect, alone or in combination with one or more of the above aspects, the base station 105, prior to receiving the uplink grant, receives a capabilities message indicating that the UE is configured for PUSCH-codebook-based BWP configuration.

[00188] In a twentieth aspect, alone or in combination with one or more of the above aspects, the base station 105, prior to receiving the uplink grant, transmits a configuration message from a network entity indicating a PUSCH-codebook-based BWP configuration mode. [00189] Accordingly, a UE and a base station may perform PUSCH-codebook-based BWP configuration. By performing PUSCH-codebook-based BWP configuration, throughput and reliability may be increased

[00190] FIG. 15 is a flow diagram illustrating example blocks executed by wireless communication device configured according to another aspect of the present disclosure. The example blocks will also be described with respect to a UE 115 as illustrated in FIG. 13 and a base station 105 (e g., gNB) as illustrated in FIG. 14.

[00191] At block 1500, a wireless communication device, such as a UE 115 or a base station 105, receives a grant indicating a data channel transmission for a particular slot, the grant including data channel resource information and including at least one of precoding information or reference signal information. In some scenarios, additionally or alternatively, the wireless communication device receives a control channel transmission (e.g., DCI or SCI) with one or more indices to indicate RBWs for the data channel transmission and its corresponding reference signal, as described with reference to FIGS. 4-12.

[00192] At block 1501, the wireless communication device transmits a reference signal during a reference signal resource associated with the data channel transmission. The reference signal resource may be determined based on the data channel resource information, or at least one of the precoding information or the reference signal information.

[00193] At block 1502, the wireless communication device transmits the data channel transmission during a data channel resource of the particular slot. The data channel resource may be determined based on the data channel resource information, and at least one of the precoding information or the reference signal information. The reference signal resource and the data channel resource correspond to RBWs of a BWP. To illustrate, and as described with respect to FIGS. 4-12, the reference signal and data channel transmission are sent in RBWs of a BWP, and the resources for reference signal and data channel transmission are associated with the RBWs, either by RBW configuration or a look-up table. The look-up table may be used with a received indicator or index value of a control channel transmission.

[00194] At block 1503, the wireless communication device receives a second transmission during the particular slot. That is, the wireless communication device operations in a full- duplex mode, such as IBFD or SBFD. In some scenarios, the wireless communication device operates in SBFD, and the second transmission is received via another signal on an overlapping bandwidth (e g., RBW) or a bandwidth (e.g., RBW) that is within the same component carrier as the data channel transmission. Aspects of these features described with reference to FIGS. 4-12. [00195] The wireless communication device may execute additional blocks (or may be configured further perform additional operations) in other implementations. For example, the wireless communication device may perform one or more operations described above. As another example, the wireless communication device may perform one or more aspects as with reference to FIGS. 11 or 12 and as described below.

[00196] In a first aspect, the second transmission is received simultaneously with the data channel transmission on an overlapping RBW or on a second RBW that is within the same component carrier as a first RBW of the data channel transmission.

[00197]

[00198] In a second aspect, alone or in combination with one or more of the above aspects, the simultaneous transmission of the data channel transmission and reception of the second transmission comprise a subband full-duplex operation (SBFD).

[00199] In a third aspect, alone or in combination with one or more of the above aspects, the data channel is a Physical Uplink Shared Channel (PUSCH) or a Physical Sidelink Shared Channel (PSSCH).

[00200] In a fourth aspect, alone or in combination with one or more of the above aspects, the wireless communication device further: determines the reference signal resource and the data channel resource based on the data channel resource information.

[00201] In a fifth aspect, alone or in combination with one or more of the above aspects, the wireless communication device further: determines the reference signal resource, the data channel resource, or both, based on the precoding information.

[00222] FIG. 16 is a flow diagram illustrating example blocks executed by wireless communication device configured according to another aspect of the present disclosure. The example blocks will also be described with respect to a UE 115 as illustrated in FIG. 13 and a base station 105 (e g., g B) as illustrated in FIG. 14.

[00223] At block 1600, a wireless communication device, such as a UE 115 or a base station 105, transmits a grant indicating a data channel transmission for a particular slot, the grant including data channel resource information and including at least one of precoding information or reference signal information. In some scenarios, additionally or alternatively, the wireless communication device receives a control channel transmission (e.g., DCI or SCI) with one or more indices to indicate RBWs for the data channel transmission and its corresponding reference signal, as described with reference to FIGS. 4-12.

[00224] At block 1601, the wireless communication device receives a reference signal during a reference signal resource associated with the data channel transmission. The reference signal resource may be determined based on the data channel resource information, or at least one of the precoding information or the reference signal information.

[00225] At block 1602, the wireless communication device receives the data channel transmission during a data channel resource of the particular slot. The data channel resource may be determined based on the data channel resource information, and at least one of the precoding information or the reference signal information. The reference signal resource and the data channel resource correspond to RBWs of a BWP. To illustrate, and as described with respect to FIGS. 4-12, the reference signal and data channel transmission are sent in RBWs of a BWP, and the resources for reference signal and data channel transmission are associated with the RBWs, either by RBW configuration or a look-up table. The look-up table may be used with a received indicator or index value of a control channel transmission.

[00226] At block 1603, the wireless communication device transmits a second transmission during the particular slot. That is, the wireless communication device operations in a full- duplex mode, such as IBFD or SBFD. In some scenarios, the wireless communication device operates in SBFD, and the second transmission is received via another signal on an overlapping bandwidth (e g., RBW) or a bandwidth (e.g., RBW) that is within the same component carrier as the data channel transmission. Aspects of these features described with reference to FIGS. 4-12.
