CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This Patent Application claims priority to United States Provisional Patent Application No. 62/987,173, filed on March 9, 2020, entitled “UE FEEDBACK REDUCTION FOR SPS,” and U.S. Nonprovisional Patent Application No. 17/149,510, filed on January 14, 2021, entitled “USER EQUIPMENT FEEDBACK REDUCTION FOR SEMI-PERSISTENT SCHEDULING,” 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 user equipment (UE) feedback reduction for semi-persistent scheduling (SPS).

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 (3GPP).

[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 3 GPP. 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.

SUMMARY

[0006] In some aspects, a method of wireless communication, performed by a user equipment (UE), may include receiving, from a base station, a semi-persistent scheduling (SPS) skipping indicator that indicates a set of SPS occasions, of an SPS communication, to be skipped, wherein the set of SPS occasions to be skipped comprises at least one SPS occasion that will not include a physical downlink shared channel (PDSCH) transmission; and ignoring the at least one SPS occasion of the set of SPS occasions by not transmitting a feedback message associated with the at least one SPS occasion.

[0010] In some aspects, a non-transitory computer-readable medium may store one or more instructions for wireless communication. The one or more instructions, when executed by one or more processors of a UE, may cause the one or more processors to receive, from a base station, an SPS skipping indicator that indicates a set of SPS occasions, of an SPS communication, to be skipped, wherein the set of SPS occasions to be skipped comprises at least one SPS occasion that will not include a PDSCH transmission; and ignore the at least one SPS occasion of the set of SPS occasions by not transmitting a feedback message associated with the at least one SPS occasion.

DETAILED DESCRIPTION

[0023] 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.

[0024] 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. [0025] 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).

[0026] Fig. 1 is a diagram illustrating an example of a wireless network 100, in accordance with various aspects of 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 3 GPP, 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.

[0027] 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 NB”, and “cell” may be used interchangeably herein.

[0028] 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.

[0029] 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.

[0030] 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).

[0031] 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, directly or indirectly, via a wireless or wireline backhaul.

[0032] 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.

[0033] 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 Intemet-of-Things (IoT) devices, and/or may be implemented as NB-IoT (narrowband internet of things) devices. 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.

[0034] 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.

[0035] 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. [0036] 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.

[0037] As indicated above, Fig. 1 is provided as an example. Other examples may differ from what is described with regard to Fig. 1.

[0038] 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 various aspects of 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

[0039] 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.

[0040] 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 channel quality indicator (CQI) parameter, among other examples. In some aspects, one or more components of UE 120 may be included in a housing 284.

[0041] 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.

[0042] 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.

[0043] 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. 4-8.

[0044] 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. 4-8.

[0045] 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 UE feedback reduction for semi-persistent scheduling (SPS), 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 700 of Fig. 7, process 800 of Fig. 8, 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 700 of Fig. 7, process 800 of Fig. 8, 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.

[0046] In some aspects, UE 120 may include means for receiving, from a base station, an SPS skipping indicator that indicates a set of SPS occasions, of an SPS communication, to be skipped, wherein the set of SPS occasions to be skipped comprises at least one SPS occasion that will not include a physical downlink shared channel (PDSCH) transmission, means for ignoring the at least one SPS occasion of the set of SPS occasions by not transmitting a feedback message associated with the at least one SPS occasion, 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.

[0047] In some aspects, base station 110 may include means for transmitting, to a UE, an SPS skipping indicator that indicates a set of SPS occasions, of an SPS communication, to be skipped, wherein the set of SPS occasions to be skipped comprises at least one SPS occasion that will not include a PDSCH transmission, means for transmitting the SPS communication, 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.

[0048] 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. [0049] As indicated above, Fig. 2 is provided as an example. Other examples may differ from what is described with regard to Fig. 2.

[0050] Fig. 3 is a diagram illustrating an example 300 of an SPS configuration, in accordance with various aspects of the present disclosure. As shown, a base station 110 and a UE 120 may communicate with one another.

[0051] As shown by reference number 305, a base station 110 may transmit an SPS configuration to a UE 120 to configure an SPS communication, which may include a set of SPS occasions 305 (shown as “SPS 1,” “SPS 2,” “SPS 3,” and “SPS 4”) for the UE 120. SPS may be used to schedule a set of downlink transmissions (referred to as an SPS communication), each downlink transmission corresponding to an SPS occasion of a set of SPS occasions, for the UE 120 without requiring individual downlink grants (e.g., in DCI) for each downlink transmission, thereby conserving signaling overhead. For example, an SPS configuration may indicate a set of resources for the set of SPS occasions, such as time resources (e.g., according to a configured periodicity and/or time offset), frequency resources, physical resource blocks (PRBs), and/or the like. Additionally, or alternatively, the SPS configuration may indicate a set of transmission parameters for the set of SPS occasions, such as a modulation and coding scheme (MCS), a resource allocation, a transport block (TB) size, a beam, a transmission configuration indication (TCI) state, and/or the like. In some aspects, a base station 110 may transmit activation DCI 310 to the UE 120 to activate an SPS configuration. Upon receiving the activation DCI 310, the UE 120 may begin monitoring for SPS transmissions scheduled according to the SPS configuration.

[0052] As shown by reference 315, the UE 120 may transmit feedback messages to the base station 110 based at least in part on each SPS occasion of the SPS configuration 305. A feedback message may include an acknowledgment (shown as “A” and interchangeably referred to as “ACK”), a negative acknowledgment (shown as “N” and interchangeably referred to as “NACK”), and/or the like. The ACKs and NACKs may be, for example, hybrid automatic repeat request (HARQ) feedback messages. Some SPS occasions may not include a PDSCH transmission. For example, some SPS occasions may be configured for retransmission of prior failed transmissions and, if prior transmissions are successful, the SPS occasions may include no data. In SPS, the UE 120 may transmit a NACK feedback message associated with an SPS occasion (e.g., SPS 2 and/or SPS 3), even if the SPS occasion does not include a PDSCH transmission.

[0053] This may increase uplink interference by increasing the quantity of uplink transmissions that may already be present. Additionally, or alternatively, transmitting feedback messages associated with SPS occasions that do not include PDSCH transmissions may increase UE power consumption as a result of the transmission itself and because the UE has to remain in an active state from the beginning of the SPS occasion until a retransmission timer expires after the UE transmits the feedback message.

[0054] Aspects of various techniques and apparatuses described herein may enable a base station 110 to provide, to a UE 120, an SPS skipping indicator that indicates a set of SPS occasions of an SPS communication, to be skipped. The set of SPS occasions to be skipped may include at least one SPS occasion that will not include a PDSCH transmission. In this way, the UE may ignore the indicated SPS occasions by not providing feedback messages associated therewith, by not performing SPS decoding associated with the indicated SPS occasions, and/or the like. This may facilitate saving resources and energy, as reactivation DCI need not be transmitted to the UE, the feedback messages are not transmitted, and the SPS occasions are not decoded. In some aspects, techniques described herein may enable the base station 110 to indicate multiple SPS occasions to be skipped, multiple SPS configurations having SPS occasions to be skipped, and/or the like. In this way, further resource and energy savings may be realized without additional signaling overhead.

[0055] As indicated above, Fig. 3 is provided as an example. Other examples may differ from what is described with regard to Fig. 3.

As shown by reference 410, the base station 110 may transmit activation DCI to the UE 120 to activate the SPS configuration. Upon receiving the activation DCI, the UE 120 may begin monitoring for SPS transmissions scheduled according to the SPS configuration.

[0058] As shown by reference 415, the base station 110 may transmit, and the UE 120 may receive, an SPS skipping indicator that indicates a set of SPS occasions, of the SPS communication, to be skipped. The set of SPS occasions to be skipped may include at least one SPS occasion that will not include a PDSCH transmission. In some aspects, the SPS skipping indicator may indicate at least one additional set of SPS occasions to be skipped.

[0059] In some aspects, the SPS skipping indicator may be carried in a medium access control (MAC) control element (CE) (shown as “MAC-CE” 420). The MAC-CE 420 may be carried in a PDSCH transmission. In some aspects, as shown, the PDSCH transmission may include an SPS PDSCH transmission (SPS 1).

[0060] In some aspects, as shown in Fig. 4, the SPS skipping indicator may indicate an initial SPS occasion to occur of the set of SPS occasions to be skipped and a quantity (shown as “#”) of SPS occasions of the set of SPS occasions to be skipped. In some aspects, the initial SPS occasion to occur may be indicated relative to an action time of the MAC-CE. The action time of the MAC-CE may include at least one of an end of an ACK message corresponding to the MAC-CE or an end of a specified time period that begins after the end of the ACK message corresponding to the MAC-CE. In some aspects, the SPS skipping indicator may not indicate an initial SPS occasion to occur of the SPS occasions to be skipped, in which case a default initial SPS occasion to occur of the SPS occasions to be skipped may include a next occasion to occur after an action time of the MAC-CE.

In some aspects, the bit map may correspond to a plurality of SPS occasions associated with a next cycle that occurs after a cycle containing an action time of the MAC-CE. The bit map may correspond to a specified quantity of SPS occasions occurring after an action time of the MAC-CE. In some aspects, the specified quantity may include a fixed quantity configured in a radio resource control (RRC) message, a dynamically -indicated quantity indicated in the MAC-CE, and/or the like.

[0063] As shown by reference 425, the UE 120 may transmit feedback messages to the base station 110 based at least in part on some SPS occasions of the SPS configuration 405. A feedback message may include an acknowledgment (shown as “A” and interchangeably referred to as “ACK”), a negative acknowledgment (shown as “N” and interchangeably referred to as “NACK”), and/or the like. The ACKs and NACKs may be, for example, HARQ feedback messages.

[0064] As shown by reference number 430, the UE 120 may ignore the at least one SPS occasion of the indicated set of SPS occasions. The UE 120 may ignore an SPS occasion by not transmitting a feedback message associated with the SPS occasion, by not performing SPS decoding associated with the SPS occasion, and/or the like. In some aspects, as indicated above, the SPS skipping indicator may indicate at least one additional set of SPS occasions to be skipped. The at least one additional set of SPS occasions may correspond to the SPS configuration associated with reference number 405 and/or another SPS configuration. In some aspects, the UE 120 may ignore each SPS occasion of the at least one additional set of SPS occasions to be skipped.

[0065] As indicated above, Fig. 4 is provided as an example. Other examples may differ from what is described with regard to Fig. 4.

As shown by reference 510, the base station 110 may transmit activation DCI to the UE 120 to activate the SPS configuration. Upon receiving the activation DCI, the UE 120 may begin monitoring for SPS transmissions scheduled according to the SPS configuration.

[0068] As shown by reference 515, the base station 110 may transmit, and the UE 120 may receive, an SPS skipping indicator that indicates a set of SPS occasions, of the SPS communication, to be skipped. The set of SPS occasions to be skipped may include at least one SPS occasion that will not include a PDSCH transmission. In some aspects, the SPS skipping indicator may indicate at least one additional set of SPS occasions to be skipped.

[0069] In some aspects, the SPS skipping indicator may be carried in a DCI transmission. The DCI transmission may be carried in any control resource set, synchronization signal, and/or the like.

For example, in some aspects, the DCI transmission may include the activation DCI shown by reference number 510. In some aspects, as shown by reference number 520, the DCI transmission may include a dedicated DCI format that is dedicated to carrying an SPS skipping indicator. In some aspects, the DCI transmission does not affect one or more discontinuous reception (DRX) timers.
