IDENTIFYING A USER EQUIPMENT ASSOCIATED WITH A PRECONFIGURED UPLINK RESOURCE

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This Patent Application claims priority to U.S. Provisional Patent Application No. 63/031,138, filed on May 28, 2020, entitled “IDENTIFYING A USER EQUIPMENT ASSOCIATED WITH A PRE-CONFIGURED UPLINK RESOURCE,” and U.S. Nonprovisional Patent Application No. 17/303,386, filed on May 27, 2021, entitled “IDENTIFYING A USER EQUIPMENT ASSOCIATED WITH A PRE- CONFIGURED UPLINK RESOURCE,” which are hereby expressly incorporated by reference herein.

FIELD OF THE DISCLOSURE

[0002] Aspects of the present disclosure generally relate to wireless communication and to techniques and apparatuses for identifying a user equipment (UE) associated with a pre-configured uplink resource (PUR).

BACKGROUND

[0003] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems may employ multiple-access technologies capable of supporting communication with multiple users by sharing available system resources (e g., bandwidth, transmit power, or the like). Examples of such multiple- access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency-division multiple access (FDMA) systems, orthogonal frequency-division multiple access (OFDMA) systems, single carrier frequency-division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and Long Term Evolution (LTE). LTE/LTE- Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3 GPP).

[0004] A wireless network may include a number of base stations (BSs) that can support communication for a number of user equipment (UEs). A UE may communicate with a BS via the downlink and uplink. The downlink (or forward link) refers to the communication link from the BS to the UE, and the uplink (or reverse link) refers to the communication link from the UE to the BS. As will be described in more detail herein, a BS may be referred to as a Node B, a gNB, an access point (AP), a radio head, a transmit receive point (TRP), a New Radio (NR) BS, a 5G Node B, or the like. [0005] The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user equipment to communicate on a municipal, national, regional, and even global level. NR, which may also be referred to as 5G, is a set of enhancements to the LTE mobile standard promulgated by the 3GPP. NR is designed to better support mobile broadband Internet access by improving spectral efficiency, lowering costs, improving services, making use of new spectrum, and better integrating with other open standards using orthogonal frequency division multiplexing (OFDM) with a cyclic prefix (CP) (CP- OFDM) on the downlink (DL), using CP-OFDM and/or SC-FDM (e.g., also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL), as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR, and other radio access technologies remain useful.

DETAILED DESCRIPTION

[0030] Various aspects of the disclosure are described more fully hereinafter with reference to the accompanying drawings. This disclosure may, however, be embodied in many different forms and should not be construed as limited to any specific structure or function presented throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. Based on the teachings herein, one skilled in the art should appreciate that the scope of the disclosure is intended to cover any aspect of the disclosure disclosed herein, whether implemented independently of or combined with any other aspect of the disclosure. For example, an apparatus may be implemented or a method may be practiced using any number of the aspects set forth herein. In addition, the scope of the disclosure is intended to cover such an apparatus or method which is practiced using other structure, functionality, or structure and functionality in addition to or other than the various aspects of the disclosure set forth herein. It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of a claim.

[0031] Several aspects of telecommunication systems will now be presented with reference to various apparatuses and techniques. These apparatuses and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, or the like (collectively referred to as “elements”). These elements may be implemented using hardware, software, or combinations thereof. Whether such elements are implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system.

[0032] It should be noted that while aspects may be described herein using terminology commonly associated with a 5G or NR radio access technology (RAT), aspects of the present disclosure can be applied to other RATs, such as a 3G RAT, a 4G RAT, and/or a RAT subsequent to 5G (e.g., 6G).

[0033] Fig. 1 is a diagram illustrating an example of a wireless network 100, in accordance with the present disclosure. The wireless network 100 may be or may include elements of a 5G (NR) network and/or an LTE network, among other examples. The wireless network 100 may include a number of base stations 110 (shown as BS 110a, BS 110b, BS 110c, and BS 1 lOd) and other network entities. A base station (BS) is an entity that communicates with user equipment (UEs) and may also be referred to as an NR BS, a Node B, a gNB, a 5G node B (NB), an access point, a transmit receive point (TRP), or the like. Each BS may provide communication coverage for a particular geographic area. In 3GPP, the term “cell” can refer to a coverage area of a BS and/or a BS subsystem serving this coverage area, depending on the context in which the term is used.

[0034] A BS may provide communication coverage for a macro cell, a pico cell, a femto cell, and/or another type of cell. A macro cell may cover a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by UEs with service subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs with service subscription. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by UEs having association with the femto cell (e.g., UEs in a closed subscriber group (CSG)). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. In the example shown in Fig. 1, a BS 110a may be a macro BS for a macro cell 102a, a BS 110b may be a pico BS for a pico cell 102b, and a BS 110c may be a femto BS for a femto cell 102c. A BS may support one or multiple (e.g., three) cells. The terms “eNB”, “base station”, “NR BS”, “gNB”, “TRP”, “AP”, “node B”, “5G B”, and “cell” may be used interchangeably herein.

[0035] In some aspects, a cell may not necessarily be stationary, and the geographic area of the cell may move according to the location of a mobile BS. In some aspects, the BSs may be interconnected to one another and/or to one or more other BSs or network nodes (not shown) in the wireless network 100 through various types of backhaul interfaces, such as a direct physical connection or a virtual network, using any suitable transport network.

[0036] Wireless network 100 may also include relay stations. A relay station is an entity that can receive a transmission of data from an upstream station (e.g., a BS or a UE) and send a transmission of the data to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that can relay transmissions for other UEs. In the example shown in Fig. 1, a relay BS 1 lOd may communicate with macro BS 110a and a UE 120d in order to facilitate communication between BS 110a and UE 120d. A relay BS may also be referred to as a relay station, a relay base station, a relay, or the like. [0037] Wireless network 100 may be a heterogeneous network that includes BSs of different types, such as macro BSs, pico BSs, femto BSs, relay BSs, or the like. These different types of BSs may have different transmit power levels, different coverage areas, and different impacts on interference in wireless network 100. For example, macro BSs may have a high transmit power level (e.g., 5 to 40 watts) whereas pico BSs, femto BSs, and relay BSs may have lower transmit power levels (e.g., 0.1 to 2 watts). [0038] A network controller 130 may couple to a set of BSs and may provide coordination and control for these BSs. Network controller 130 may communicate with the BSs via a backhaul. The BSs may also communicate with one another, e.g., directly or indirectly via a wireless or wireline backhaul.

[0039] UEs 120 (e.g., 120a, 120b, 120c) may be dispersed throughout wireless network 100, and each UE may be stationary or mobile. A UE may also be referred to as an access terminal, a terminal, a mobile station, a subscriber unit, a station, or the like. A UE may be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or equipment, biometric sensors/devices, wearable devices (smart watches, smart clothing, smart glasses, smart wrist bands, smart jewelry (e.g., smart ring, smart bracelet)), an entertainment device (e.g., a music or video device, or a satellite radio), a vehicular component or sensor, smart meters/sensors, industrial manufacturing equipment, a global positioning system device, or any other suitable device that is configured to communicate via a wireless or wired medium.

[0040] Some UEs may be considered machine-type communication (MTC) or evolved or enhanced machine-type communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, and/or location tags, that may communicate with a base station, another device (e.g., remote device), or some other entity. A wireless node may provide, for example, connectivity for or to a network (e.g., a wide area network such as Internet or a cellular network) via a wired or wireless communication link. Some UEs may be considered Internet-of- Things (IoT) devices, and/or may be implemented as NB-IoT (narrowband internet of things) devices. MTC or IoT UEs may include eMTC (also referred to as CAT-M, or Cat Ml) UEs, NB-IoT (also referred to as CAT NB1) UEs, as well as other types of UEs. eMTC and NB-IoT may refer to future technologies that may evolve from or may be based on these technologies. For example, eMTC may include FeMTC (further eMTC), eFeMTC (enhanced further eMTC), and mMTC (massive MTC), and NB-IoT may include eNB-IoT (enhanced NB-IoT), and FeNB-IoT (further enhanced NB-IoT). Some UEs may be considered a Customer Premises Equipment (CPE). UE 120 may be included inside a housing that houses components of UE 120, such as processor components and/or memory components. In some aspects, the processor components and the memory components may be coupled together. For example, the processor components (e.g., one or more processors) and the memory components (e.g., a memory) may be operatively coupled, communicatively coupled, electronically coupled, and/or electrically coupled.

[0041] In general, any number of wireless networks may be deployed in a given geographic area. Each wireless network may support a particular RAT and may operate on one or more frequencies. A RAT may also be referred to as a radio technology, an air interface, or the like. A frequency may also be referred to as a carrier, a frequency channel, or the like. Each frequency may support a single RAT in a given geographic area in order to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.

[0042] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e g., without using a base station 110 as an intermediary to communicate with one another). For example, the UEs 120 may communicate using peer-to-peer (P2P) communications, device-to- device (D2D) communications, a vehicle-to-everything (V2X) protocol (e g., which may include a vehicle-to-vehicle (V2V) protocol or a vehicle-to-infrastructure (V2I) protocol), and/or a mesh network. In this case, the UE 120 may perform scheduling operations, resource selection operations, and/or other operations described elsewhere herein as being performed by the base station 110.

[0043] Devices of wireless network 100 may communicate using the electromagnetic spectrum, which may be subdivided based on frequency or wavelength into various classes, bands, channels, or the like. For example, devices of wireless network 100 may communicate using an operating band having a first frequency range (FR1), which may span from 410 MHz to 7.125 GHz, and/or may communicate using an operating band having a second frequency range (FR2), which may span from 24.25 GHz to 52.6 GHz. The frequencies between FR1 and FR2 are sometimes referred to as mid-band frequencies. Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to as a “sub-6 GHz” band. Similarly, FR2 is often referred to as a “millimeter wave” band despite being different from the extremely high frequency (EHF) band (30 GHz - 300 GHz) which is identified by the International Telecommunications Union (ITU) as a “millimeter wave” band. Thus, unless specifically stated otherwise, it should be understood that the term “sub-6 GHz” or the like, if used herein, may broadly represent frequencies less than 6 GHz, frequencies within FR1, and/or mid-band frequencies (e.g., greater than 7.125 GHz). Similarly, unless specifically stated otherwise, it should be understood that the term “millimeter wave” or the like, if used herein, may broadly represent frequencies within the EHF band, frequencies within FR2, and/or mid-band frequencies (e.g., less than 24.25 GHz). It is contemplated that the frequencies included in FR1 and FR2 may be modified, and techniques described herein are applicable to those modified frequency ranges. [0044] As indicated above, Fig. 1 is provided as an example. Other examples may differ from what is described with regard to Fig. 1.

[0045] Fig. 2 is a diagram illustrating an example 200 of a base station 110 in communication with a UE 120 in a wireless network 100, in accordance with the present disclosure. Base station 110 may be equipped with T antennas 234a through 234t, and UE 120 may be equipped with R antennas 252a through 252r, where in general T > 1 and R > 1.

[0046] At base station 110, a transmit processor 220 may receive data from a data source 212 for one or more UEs, select one or more modulation and coding schemes (MCS) for each UE based at least in part on channel quality indicators (CQIs) received from the UE, process (e.g., encode and modulate) the data for each UE based at least in part on the MCS(s) selected for the UE, and provide data symbols for all UEs. Transmit processor 220 may also process system information (e g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and/or upper layer signaling) and provide overhead symbols and control symbols. Transmit processor 220 may also generate reference symbols for reference signals (e.g., a cell-specific reference signal (CRS) or a demodulation reference signal (DMRS)) and synchronization signals (e.g., a primary synchronization signal (PSS) or a secondary synchronization signal (SSS)). A transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on the data symbols, the control symbols, the overhead symbols, and/or the reference symbols, if applicable, and may provide T output symbol streams to T modulators (MODs) 232a through 232t.

Each modulator 232 may process a respective output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modulator 232 may further process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. T downlink signals from modulators 232a through 232t may be transmitted via T antennas 234a through 234t, respectively.

[0047] At UE 120, antennas 252a through 252r may receive the downlink signals from base station 110 and/or other base stations 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 received signal to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 may obtain received symbols from all R demodulators 254a through 254r, perform MIMO detection on the received symbols if applicable, and provide detected symbols. A receive processor 258 may process (e g., demodulate and decode) the detected symbols, provide decoded data for UE 120 to a data sink 260, and provide decoded control information and system information to a controller/processor 280. The term “controller/processor” may refer to one or more controllers, one or more processors, or a combination thereof. A channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and/or a CQI parameter, among other examples. In some aspects, one or more components of UE 120 may be included in a housing 284.

[0048] Network controller 130 may include communication unit 294, controller/processor 290, and memory 292. Network controller 130 may include, for example, one or more devices in a core network. Network controller 130 may communicate with base station 110 via communication unit 294.

[0049] Antennas (e.g., antennas 234a through 234t and/or antennas 252a through 252r) may include, or may be included within, one or more antenna panels, antenna groups, sets of antenna elements, and/or antenna arrays, among other examples. An antenna panel, an antenna group, a set of antenna elements, and/or an antenna array may include one or more antenna elements. An antenna panel, an antenna group, a set of antenna elements, and/or an antenna array may include a set of coplanar antenna elements and/or a set of non-coplanar antenna elements. An antenna panel, an antenna group, a set of antenna elements, and/or an antenna array may include antenna elements within a single housing and/or antenna elements within multiple housings. An antenna panel, an antenna group, a set of antenna elements, and/or an antenna array may include one or more antenna elements coupled to one or more transmission and/or reception components, such as one or more components of Fig. 2.

[0050] On the uplink, at UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information (e.g., for reports that include RSRP, RSSI, RSRQ, and/or CQI) from controller/processor 280. Transmit processor 264 may also generate reference symbols for one or more reference signals. The symbols from transmit processor 264 may be precoded by a TX MIMO processor 266 if applicable, further processed by modulators 254a through 254r (e.g., for DFT-s-OFDM or CP- OFDM), and transmitted to base station 110. In some aspects, a modulator and a demodulator (e.g., MOD/DEMOD 254) of the UE 120 may be included in a modem of the UE 120. In some aspects, the UE 120 includes a transceiver. The transceiver may include any combination of antenna(s) 252, modulators and/or demodulators 254, MIMO detector 256, receive processor 258, transmit processor 264, and/or TX MIMO processor 266. The transceiver may be used by a processor (e.g., controller/processor 280) and memory 282 to perform aspects of any of the methods described herein, for example, as described with reference to Figs. 3-7.

[0051] At base station 110, the uplink signals from UE 120 and other UEs may be received by antennas 234, processed by demodulators 232, detected by a MIMO detector 236 if applicable, and further processed by a receive processor 238 to obtain decoded data and control information sent by UE 120. Receive processor 238 may provide the decoded data to a data sink 239 and the decoded control information to controller/processor 240. Base station 110 may include communication unit 244 and communicate to network controller 130 via communication unit 244. Base station 110 may include a scheduler 246 to schedule UEs 120 for downlink and/or uplink communications. In some aspects, a modulator and a demodulator (e.g., MOD/DEMOD 232) of the base station 110 may be included in a modem of the base station 110. In some aspects, the base station 110 includes a transceiver. The transceiver may include any combination of antenna(s) 234, modulators and/or demodulators 232, MIMO detector 236, receive processor 238, transmit processor 220, and/or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller/processor 240) and memory 242 to perform aspects of any of the methods described herein, for example, as described with reference to Figs. 3-7.

[0052] Controller/processor 240 of base station 110, controller/processor 280 of UE 120, and/or any other component(s) of Fig. 2 may perform one or more techniques associated with identifying a UE associated with a PUR, as described in more detail elsewhere herein. For example, controller/processor 240 of base station 110, controller/processor 280 of UE 120, and/or any other component(s) of Fig. 2 may perform or direct operations of, for example, process 400 of Fig. 4, process 500 of Fig. 5, process 600 of Fig. 6, process 700 of Fig. 7, and/or other processes as described herein. Memories 242 and 282 may store data and program codes for base station 110 and UE 120, respectively. In some aspects, memory 242 and/or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and/or program code) for wireless communication. For example, the one or more instructions, when executed (e.g., directly, or after compiling, converting, and/or interpreting) by one or more processors of the base station 110 and/or the UE 120, may cause the one or more processors, the UE 120, and/or the base station 110 to perform or direct operations of, for example, process 400 of Fig. 4, process 500 of Fig. 5, process 600 of Fig. 6, process 700 of Fig. 7, and/or other processes as described herein. In some aspects, executing instructions may include running the instructions, converting the instructions, compiling the instructions, and/or interpreting the instructions, among other examples.

[0053] In some aspects, UE 120 may include means for determining information indicating an association between the UE 120 and a preconfigured uplink resource (PUR); means for transmitting a message including the information indicating the association between the UE and the PUR; and/or the like. In some aspects, such means may include one or more components of UE 120 described in connection with Fig. 2, such as controller/processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, and/or the like.

[0054] In some aspects, UE 120 may include means for receiving, from a base station 110, a message including a PUR configuration, wherein the message including the PUR configuration does not include information indicating an association between the UE 120 and the PUR configuration; means for determining that an identifier of the UE that was used to establish a radio resource control connection prior to the receiving of the message including the PUR configuration was modified; transmitting a request to release a PUR or a request to reconfigure the PUR using only an uplink resource configured based on the PUR based at least in part on the determining; and/or the like.

In some aspects, such means may include one or more components of UE 120 described in connection with Fig. 2, such as controller/processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, and/or the like.

[0055] In some aspects, base station 110 may include means for receiving a message including information indicating an association between a UE 120 and the PUR; means for identifying the UE 120 associated with the PUR based at least in part on the information indicating the association between the UE and the PUR; and/or the like. In some aspects, such means may include one or more components of base station 110 described in connection with Fig. 2, such as antenna 234, DEMOD 232, MIMO detector 236, receive processor 238, controller/processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234, and/or the like. [0056] In some aspects, base station 110 may include means for transmitting, to a UE 120, a message including a PUR configuration, wherein the message including the PUR configuration does not include information indicating an association between the UE 120 and the PUR configuration; means for configuring the UE 120 to transmit a request to release a PUR or a request to reconfigure the PUR using only an uplink resource configured based on the PUR when an identifier of the UE 120 that was used to establish a radio resource control connection prior to the transmitting of the message including the PUR configuration is modified; and/or the like. In some aspects, such means may include one or more components of base station 110 described in connection with Fig. 2, such as antenna 234, DEMOD 232, MEMO detector 236, receive processor 238, controller/processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234, and/or the like.

[0057] While blocks in Fig. 2 are illustrated as distinct components, the functions described above with respect to the blocks may be implemented in a single hardware, software, or combination component or in various combinations of components. For example, the functions described with respect to the transmit processor 264, the receive processor 258, and/or the TX MIMO processor 266 may be performed by or under the control of controller/processor 280.

[0058] As indicated above, Fig. 2 is provided as an example. Other examples may differ from what is described with regard to Fig. 2.

[0059] Some wireless communication systems, such as an NR or an LTE system, including an eMTC or an NB-IoT system, may be designed to permit a UE (e.g., a UE 120) to transmit uplink data during the random access procedure by shortening the random access procedure, such as omitting first and second messages and transmitting uplink data in a third message of a random access procedure (e.g., msg3 of a four-step random access procedure). In such a case, the UE may transmit the uplink data in an uplink resource that was previously configured on the UE by the network (e.g., by a base station 110). The uplink resource that is preconfigured for the UE to permit this shortening of the random access procedure and transmission of uplink data is herein referred to as a PUR.

[0060] In general, a UE in radio resource control (RRC) idle mode that has a valid timing advance (TA) (e.g., a stationary UE) may utilize a PUR. Notably, a PUR is a grant-free approach to UL data transmission that can improve uplink transmission efficiency and power consumption for, for example, an enhanced machine type communication (eMTC) UE, a narrowband Internet-of-things (NB-IoT) UE, or the like. PURs can be used for transmission of both user plane data and control plane data using user plane consumer IoT EPS/5GS optimization and control plane consumer IoT EPS/5GS optimization, which is referred to as transmission using user plane PUR and transmission using control plane PUR respectively. PUR can be contention-free dedicated (D-PUR), contention-free shared (CFS-PUR) or contention-based shared (CBS-PUR). Notably, an applicable wireless communication standard may not differentiate between D-PUR and CFS-PUR, meaning that it is up to the network (e.g., a base station 110) to determine whether a given resource (e.g., a time/frequency resource) is configured to one UE or to multiple to UEs (with different DMRS cyclic shifts for resolving contention).

[0061] In operation, to be configured with a PUR, a UE may transmit a message including a request to be configured with a PUR. The UE may transmit the message to a base station while the UE is in an RRC connected mode. Notably, the same message can be used to request a release of the PUR, as described below. The base station may receive the request and provide a PUR configuration to the UE, the PUR configuration including information associated with a PUR allocated for the UE. Notably, in some cases, the base station may provide the UE with the PUR configuration without a request from the UE. The PUR configuration may be provided to the UE in, for example, an RRC connection release message. The UE may receive the PUR configuration, and may then use the PUR for uplink data transmission in the manner described above. After configuration of the PUR, the UE may decide to skip one or more PUR occasions (e.g., when the UE does not have any uplink data to transmit in the PUR). In such a case, the UE may transmit a message to a base station (while the UE is in an RRC connected mode) including a request to release the PUR. However, the message including the request to release the PUR does not include any specific information associated with the PUR, which can be problematic in the case of a PUR. [0062] For example, a base station may configure a first UE with a first PUR and a second UE with a second PUR, and the first UE and the second UE may be operating in RRC idle mode. The second UE may trigger an RRC connection (e.g., to switch from RRC idle mode to RRC connected mode) and, during establishment of the RRC connection, may transmit a message including a PUR release request. Thereafter, the second UE may skip a PUR occasion, associated with the second PUR, that occurs during establishment of the RRC connection. In this example, the first UE decides to skip a PUR occasion, associated with the first PUR, that occurs during establishment of the RRC connection by the second UE. Here, the base station may receive the PUR release request from the second UE, but if an identifier of the second UE (e.g., a system architecture evolution temporary mobile subscriber identity (S-TMSI)) has been modified since the second UE was configured with the second PUR, the base station is unable to identify which PUR (the first PUR associated with the first UE or the second PUR associated with the second UE) is to be released (e.g., since the PUR release request does not include any specific information associated with the second PUR). As a result, the base station may mistakenly release the first PUR in response to the PUR release request provided by the second UE. Further, in a case in which the PUR is shared between the first and second UEs (e.g., if the first and second PURs are the same CFS-PUR) the base station will be unable to identify the UE for which the release should be performed even if the base station is able to identify the PUR to be released. [0063] Some aspects described herein provide techniques and apparatuses for identifying a UE associated with a PUR. In some aspects, a UE may determine information indicating an association between the UE and a PUR, and may transmit a message including the information indicating the association between the UE and the PUR. In some aspects, the base station may receive the message including the information indicating the association between the UE and the PUR, may identify the UE associated with the PUR based at least in part on the information indicating the association between the UE and the PUR, and may proceed accordingly (e.g., release the PUR, reconfigure the PUR, or the like). Additional details are provided below. [0064] Fig. 3 is a diagram illustrating an example 300 associated with identifying a UE associated with a PUR, in accordance with the present disclosure.

[0065] As shown by reference 305, a base station (e.g., a base station 110) may transmit, and a UE (e.g., a UE 120) may receive, a PUR configuration. The PUR configuration may include information associated with a PUR that may be used by the UE for transmitting uplink data (e.g., when the UE is operating in RRC idle mode). For example, the PUR configuration may include information that identifies one or more time/frequency resources that can be used by the UE for transmitting uplink data (e.g., while the UE is in RRC idle mode). In some aspects, the PUR associated with the PUR configuration may be a D-PUR. In some aspects, the PUR associated with the PUR configuration may be a CFS-PUR. [0066] In some aspects, the PUR configuration may be transmitted by the base station, and received by the UE, in an RRC connection release message.

[0067] In some aspects, the base station may transmit the PUR configuration based at least in part on a UE request. For example, the UE (e.g., while operating in RRC connected mode) may transmit a PUR message including a request to be configured with a PUR. The base station may receive the PUR message including the request, and may transmit the PUR configuration to the UE based at least in part on the request. Additionally, or alternatively, the base station may transmit the PUR configuration to the UE without a request from the UE (e.g., the base station may transmit the PUR configuration to the UE based at least in part on a configuration or implementation of the base station, based at least in part on an indication from another wireless communication device, or the like). In some aspects, the PUR configuration may include information indicating an association between the UE and the PUR. Additional details regarding the information indicating the association between the UE and the PUR are described below.

[0068] In some aspects, the UE may decide to request a release of the PUR or a reconfiguration of the PUR. For example, the UE may decide to request a release of the PUR when the UE has triggered an RRC connection (e.g., to switch from RRC idle mode to RRC connected mode). As another example, the UE may decide to request a reconfiguration of the PUR when the UE needs additional uplink resources, is unable to use the resources as configured based on the PUR, or the like.

[0069] As shown by reference 310, the UE may determine information indicating an association between the UE and the PUR and, as shown by reference 315, may transmit a message including the information indicating the association between the UE and the PUR (e.g., pur-ConfigID-rl6). In some implementations, the message may be an RRC message, such as an RRC connection setup complete message. In some implementations (e.g., when the UE has decided to request a release of the PUR or a reconfiguration of the PUR), the message may include a request to release the PUR or a request to reconfigure the PUR. Here, the message may include the information indicating the association between the UE and the PUR. In some aspects, the UE may determine the information indicating the association between the UE and the PUR and transmit the message based at least in part on a decision to request the release or the reconfiguration of the PUR. [0070] In some aspects, the information indicating the association between the UE and the PUR includes a PUR radio network temporary identifier (RNTI). For example, in some aspects, the PUR configuration provided by the base station and received by the UE may include the PUR RNTI. In some aspects, if the PUR RNTI is unique across all UEs associated with the base station, then PUR RNTI may be used by the base station to identify the UE and thus the associated PUR configuration.

[0071] In some aspects, the information indicating the association between the UE and the PUR may include at least a portion of an identifier of the UE at a time at which the PUR was configured or last reconfigured. For example, the information indicating the association between the UE and the PUR may include at least a portion of an S- TMSI (e.g., a full S-TMSI, a portion of the S-TMSI, a truncated S-TMSI, or the like), associated with the UE, that was used to establish an RRC connection prior to the PUR configuration being received by the UE. In some aspects, the UE may store the identifier of the UE based at least in part on the identifier of the UE being modified after the time at which the PUR was configured or reconfigured. For example, the UE may be configured with a first S-TMSI at a time at which the PUR is configured for the UE. After configuration of the PUR, the UE may be reconfigured with a second (different) S-TMSI. Here, upon modification of the S-TMSI (i .e., upon configuration of the second S-TMSI), the UE may store the first S-TMSI. In this example, the UE may include the first S-TMSI in the message when requesting the release or reconfiguration of the PUR (e g., since the PUR may be tagged with the first S-TMSI at the base station).

[0072] In some aspects, the information indicating the association between the UE and the PUR may include a PUR RNTI associated with the UE and a RNTI resolution identifier associated with the UE (e.g., a combination of a PUR RNTI associated with the UE and a RNTI resolution identifier associated with the UE). For example, in some aspects, the PUR configuration provided by the base station and received by the UE may include the PUR RNTI and a RNTI resolution identifier. In some aspects, the RNTI resolution identifier may include one or more bits (e.g., four to eight bits). In some aspects, if the PUR RNTI is not unique across all UEs associated with the base station, then RNTI resolution identifier, when combined with PUR RNTI, may be used by the base station to identify the UE and thus the associated PUR configuration. In some aspects, the PUR RNTI may have a size of 16 bits, meaning that a relatively small number of bits (e.g., four to eight bits) are needed for the RNTI resolution identifier (e.g., since a combination of the PUR RNTI and the RNTI resolution identifier would be 20 to 24 bits, which enables approximately 1 million to 16 million unique identifiers).

[0073] In some aspects, the information indicating the association between the UE and the PUR may include only the RNTI resolution identifier associated with the UE. For example, in some aspects, the PUR configuration provided by the base station and received by the UE may include the RNTI resolution identifier. In some aspects, the RNTI resolution identifier may include approximately 20 bits. In some aspects, if the RNTI resolution identifier is unique across all UEs associated with the base station, then RNTI resolution identifier may be used by the base station to identify the UE and thus the associated PUR configuration. In some aspects, use of such a RNTI resolution identifier renders inclusion of the PUR RNTI in the PUR configuration optional.

[0074] In some aspects, the information indicating the association between the UE and the PUR may include a PUR identifier associated with the UE. For example, in some aspects, the PUR configuration provided by the base station and received by the UE may include the PUR identifier. In some aspects, the PUR identifier may include multiple bits (e.g., 10 bits) and may be unique for each PUR configuration in a given cell. In some aspects, if the PUR identifier may be used by the base station to identify the UE and thus the associated PUR configuration.

[0075] In some aspects, the information indicating the association between the UE and the PUR may include information associated with a grant associated with the PUR configuration. The information associated with the grant may include, for example, information that identifies time/frequency resources associated with the grant. In some aspects, the information associated with the grant may include partial information associated with the grant. For example, the information associated with the grant may include the information that identifies time/frequency resources associated with the grant, but may not include a modulation and coding scheme (MCS) associated with the grant. In some aspects, the information associated with the grant may include information that identifies a DMRS cyclic shift (e.g., to resolve ambiguity in the case of a CFS-PUR). In some aspects, the UE may calculate a hash of the information associated with the grant, and may include the hash in the message (e.g., to prevent a UE from attempting to release a PUR of another).

[0076] In some aspects, the UE may include the information indicating the association between the UE and the PUR (e.g., pur-ConfigID-rl6) in the message based at least in part on a determination that an identifier of the UE (e.g., S-TMSI) has been modified since a time at which the PUR was configured or last reconfigured. For example, the UE may be configured with a first S-TMSI at a time at which the PUR is configured for the UE. After or prior to transmitting the downlink message containing the configuration of the PUR, the UE may be reconfigured with a second (different) S- TMSI. Here, upon modification of the S-TMSI (i.e., upon configuration of the second S-TMSI), the UE may set a flag indicating that the S-TMSI has been modified since configuration of the PUR. In this example, when preparing the message, the UE may check the flag and determine that the S-TMSI has been modified since configuration of the PUR. Based at least in part on this determination, the UE may then include the information indicating the association between the UE (e g., the PUR RNTI, the first S- TMSI, the PUR RNTI and the RNTI resolution identifier, the PUR identifier, or the information associated with the grant) in the message requesting the release or reconfiguration of the PUR.

[0077] As indicated by reference 315, the base station may receive the message including the information indicating an association between the UE and the PUR. As shown by reference 320, the base station may identify the UE associated with the PUR based at least in part on the information indicating the association between the UE and the PUR.

[0078] In some aspects, as indicated by reference 325, the base station may release the PUR. For example, the base station may receive a PUR message including a request to release the PUR, and release the PUR based at least in part on identifying the UE associated with the PUR as described above with respect to the reference 320.

[0079] In some aspects, as indicated by reference 325, the base station may reconfigure the PUR. For example, the base station may receive the a PUR message including a request to reconfigure the PUR, and reconfigure the PUR based at least in part on identifying the UE associated with the PUR as described above with respect to the reference 320.

[0080] As an alternative to the above aspects, in some aspects, the base station may transmit, to the UE, a message including a PUR configuration, where the message does not include information indicating an association between the UE and the PUR configuration. In this context, the PUR configuration may include an initial configuration of a PUR (i.e., the message may be associated with initially configuring a PUR) or a reconfiguration of a PUR (i.e., the message may be associated with reconfiguring a previously configured PUR). In such a case, the UE may be configured (e g., based at least in part on an indication provided by the base station, based at least in part on an applicable wireless communication standard, or the like) to refrain from transmitting a request to release the PUR or a request to reconfigure the PUR without using the PUR when an identifier of the UE (e.g., an S-TMSI that was used to establish an RRC connection prior to the transmitting of the message including the PUR configuration) is modified. In other words, the UE may be configured (e g., based at least in part on an indication provided by the base station, based at least in part on an applicable wireless communication standard, or the like) to transmit a request to release the PUR or a request to reconfigure the PUR using only an uplink resource configured based on the PUR. For example, the base station may tag the PUR configuration with the identifier of the UE (e.g., the S-TMSI at the time of the PUR configuration) and, when transmitting the PUR configuration, may not include information indicating an association between the UE and the PUR (e.g., a PUR RNTI, a RNTI resolution identifier, a PUR identifier, or the like) in the PUR configuration. Here, the UE may be configured (e.g., based at least in part on an indication provided by the base station, based at least in part on an applicable wireless communication standard, or the like) such that, upon receiving a PUR configuration that does not include information indicating an association between the UE and the PUR, the UE will not transmit a message including a request to release or reconfigure the PUR configuration without using the PUR if the S-TMSI is modified. Otherwise (i.e., if the S-TMSI is not modified), then the UE may be permitted to request release or reconfiguration of the PUR without using the PUR. In some aspects, the base station may explicitly configure the UE to refrain from transmitting a request to release the PUR or a request to reconfigure the PUR when the information identifying the association between the UE and the PUR is not included in the PUR configuration message. Additionally, or alternatively, the UE may be implicitly configured (e.g., based at least in part on an applicable wireless communication standard) to refrain from transmitting a request to release the PUR or a request to reconfigure the PUR when the information identifying the association between the UE and the PUR is not included in the PUR configuration message.
