Techniques to activate semi-persistent scheduling (SPS) occasions

Abstract

Methods, systems, and devices for wireless communications are described. In some examples, a user equipment (UE) may receive, via a first radio, control signaling that indicates a configuration associated with a wake-up signal (WUS) and that also indicates an association between the WUS and a semi-persistent scheduling (SPS) occasion. As such, the UE may monitor, via a second radio, for the WUS in accordance with the control signaling, where the WUS may indicate whether the SPS occasion includes a physical downlink shared channel (PDSCH) transmission. For example, if the WUS indicates that the SPS occasion includes the PDSCH transmission, the UE may perform a first procedure pertaining to monitoring, via the first radio, the SPS occasion. Alternatively, if the WUS indicates that the SPS occasion is empty, the UE may perform a second procedure pertaining to maintaining the first radio in a sleep mode.

TECHNIQUES TO ACTIVATE SEMI-PERSISTENT SCHEDULING (SPS) OCCASIONSCROSS REFERENCE

[0001] The present Application for Patent claims priority to U.S. Patent Application No. 18 / 596,546 by DUAN et al., entitled “TECHNIQUES TO ACTIVATE SEMIPERSISTENT SCHEDULING (SPS) OCCASIONS,” filed March 5, 2024, which is assigned to the assignee hereof and expressly incorporated by reference herein.FIELD OF TECHNOLOGY

[0002] The following relates to wireless communications, including techniques to activate semi-persistent scheduling (SPS) occasions.BACKGROUND

[0003] Wireless communications systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and so on. These systems may be capable of supporting communication with multiple users by sharing the available system resources (e.g.. time, frequency, and power). Examples of such multiple-access systems include fourth generation (4G) systems such as Long Term Evolution (LTE) systems, LTE-Advanced (LTE-A) systems, or LTE-A Pro systems, and fifth generation (5G) systems which may be referred to as New Radio (NR) systems. These systems may employ technologies such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal FDMA (OFDMA), or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM). A wireless multiple-access communications system may include one or more base stations, each supporting wireless communication for communication devices, which may be known as user equipment (UE).SUMMARY

[0004] The described techniques relate to improved methods, systems, devices, and apparatuses that support techniques to activate semi-persistent scheduling (SPS) occasions. For example, the described techniques provide for SPS monitoringindications via a wake-up signal (WUS). In some examples, a UE may receive, via a first radio while operating in an active mode, control signaling indicating a configuration for a low-power WUS, where the control signaling may further indicate the WUS is associated with (e.g., contains information for) one or more SPS occasions. For example, the control signaling may indicate that the WUS is associated with a single SPS occasion. Alternatively, the control signaling may indicate that the WUS is associated with multiple SPS occasions. Accordingly, based on the control signaling, the UE may monitor, via a second radio while the first radio is operating in the sleep mode, for the WUS, where the WUS may indicate whether the associated SPS occasions include a physical downlink shared channel (PDSCH). If the WUS indicates that the associated SPS occasions include a PDSCH, the UE may perform a first procedure to wake-up the first radio, monitor the SPS occasions, and receive the PDSCHs. Alternatively, if the WUS indicates that the associated SPS occasions are empty (e.g., do not include a PDSCH transmission), the UE may maintain the first radio in the sleep mode.

The method may include receiving, via a first radio at the UE, control signaling that indicates a configuration associated with a WUS and that also indicates an association between the WUS and a SPS occasion, monitoring, via a second radio at the UE, for the WUS in accordance with the configuration, and performing one of a first procedure or a second procedure based on the monitoring, the first procedure pertaining to monitoring, via the first radio, the SPS occasion, and the second procedure pertaining to maintaining the first radio of the UE in a sleep mode.

[0051] In some wireless communications system, a network entity may communicate with a user equipment (UE) via semi-persistent scheduling (SPS). For example, a network entity may transmit, via radio resource control (RRC) signaling, a configuration indicating periodic SPS occasions (e.g.. periodic time and frequency resources). The network entity may transmit, to the UE, downlink control information activating the SPS configuration, such that the UE may have an indication of when to begin monitoring the SPS occasions. By using the SPS occasions, the network entity may transmit a physical downlink shared channel (PDSCH) to the UE without first transmitting multiple scheduling DCIs.

[0052] In some cases, a main radio of the UE may enter a sleep mode (e g., an inactive mode), w here the UE may power off the main radio and use a low-pow er w akeup radio (LP-WUR) to monitor for a w ake-up signal (WUS). In such cases, if the SPS configuration is activated, then the UE may wake-up the main radio prior to each SPS occasion, monitor the SPS occasion, and receive the PDSCH transmission. In some cases, however, one of the multiple of the periodic SPS occasions may be empty (e.g., not include a PDSCH transmission), which may cause the UE to unnecessarily wake-up the main radio and monitor the SPS occasion, thereby reducing power savings at the UE.

[0053] The techniques described herein may enable the network entity to indicate, via the WUS, whether one or more of the periodic SPS occasions will be empty (e.g.,whether one or more of the multiple SPS occasions include a PDSCH transmission), thereby reducing the quantity of times at which the UE wakes up to monitor an empty SPS occasion. For example, the UE may receive, via the main radio, control signaling indicating a configuration associated with the WUS (e.g., one or more time and frequency resources for the WUS, waveform parameters, sequence parameters, or a combination thereof) and also indicating an association between the WUS and a SPS occasion (e.g., that the WUS contains information associated with the SPS occasion). Accordingly, the UE may monitor, via the LP-WUR and while the main radio is operating in the sleep mode, for the WUS. where the WUS may indicate whether the associated SPS occasion includes a PDSCH transmission. For example, the WUS may indicate that the SPS occasion does include a PDSCH transmission and, as such, the UE may wake-up the main radio and monitor the SPS occasion for the PDSCH transmission. Alternatively, the WUS may indicate that the SPS occasion does not include a PDSCH transmission (e.g., is empty) and, as such, the UE may not wake-up the main radio. In this way, the network entity may indicate whether the SPS occasion includes a PDSCH transmission via the WUS.

[0054] Aspects of the disclosure are initially described in the context of wireless communications systems. Aspects are further described in the context of process flow. Aspects of the disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flowcharts that relate to techniques to activate SPS occasions.

[0055] FIG. 1 shows an example of a wireless communications system 100 that supports techniques to activate SPS occasions in accordance with one or more aspects of the present disclosure. The wireless communications system 100 may include one or more devices, such as one or more network devices (e.g., network entities 105), one or more UEs 115, and a core network 130. In some examples, the wireless communications system 100 may be a Long Term Evolution (LTE) network, an LTE- Advanced (LTE- A) network, an LTE- A Pro network, a New Radio (NR) network, or a network operating in accordance with other systems and radio technologies, including future systems and radio technologies not explicitly mentioned herein.

[0056] The network entities 105 may be dispersed throughout a geographic area to form the wireless communications system 100 and may include devices in differentforms or having different capabilities. In various examples, a network entity 105 may be referred to as a network element, a mobility element, a radio access network (RAN) node, or network equipment, among other nomenclature. In some examples, network entities 105 and UEs 115 may wirelessly communicate via communication link(s) 125 (e.g., a radio frequency (RF) access link). For example, a network entity 105 may support a coverage area 110 (e.g., a geographic coverage area) over which the UEs 115 and the network entity 105 may establish the communication link(s) 125. The coverage area 110 may be an example of a geographic area over which a network entity 105 and a UE 115 may support the communication of signals according to one or more radio access technologies (RATs).

[0057] The UEs 115 may be dispersed throughout a coverage area 110 of the wireless communications system 100, and each UE 115 may be stationary, or mobile, or both at different times. The UEs 115 may be devices in different forms or having different capabilities. Some example UEs 115 are illustrated in FIG. 1. The UEs 115 described herein may be capable of supporting communications with various ty pes of devices in the wireless communications system 100 (e.g., other wireless communication devices, including UEs 115 or network entities 105), as shown in FIG. 1.

[0058] As described herein, a node of the wireless communications system 100, which may be referred to as a network node, or a wireless node, may be a network entity’ 105 (e.g., any network entity described herein), a UE 115 (e.g., any UE described herein), a network controller, an apparatus, a device, a computing system, one or more components, or another suitable processing entity configured to perform any of the techniques described herein. For example, a node may be a UE 115. As another example, a node may be a network entity 105. As another example, a first node may be configured to communicate with a second node or a third node. In one aspect of this example, the first node may be a UE 115, the second node may be a network entity 105, and the third node may be a UE 115. In another aspect of this example, the first node may be a UE 115, the second node may be a network entity 105, and the third node may be a network entity’ 105. In yet other aspects of this example, the first, second, and third nodes may be different relative to these examples. Similarly, reference to a UE 115, network entity 105, apparatus, device, computing system, or the like may include disclosure of the UE 115, network entity 105, apparatus, device, computing system, orthe like being a node. For example, disclosure that a UE 1 15 is configured to receive information from a network entity 105 also discloses that a first node is configured to receive information from a second node.

[0059] In some examples, network entities 105 may communicate with a core network 130. or with one another, or both. For example, network entities 105 may communicate with the core network 130 via backhaul communication link(s) 120 (e.g., in accordance with an SI, N2, N3, or other interface protocol). In some examples, network entities 105 may communicate with one another via backhaul communication link(s) 120 (e.g., in accordance with an X2, Xn, or other interface protocol) either directly (e.g., directly betw een network entities 105) or indirectly (e.g., via the core network 130). In some examples, network entities 105 may communicate with one another via a midhaul communication link 162 (e.g., in accordance with a midhaul interface protocol) or a fronthaul communication link 168 (e.g., in accordance with a fronthaul interface protocol), or any combination thereof. The backhaul communication link(s) 120, midhaul communication links 162, or fronthaul communication links 168 may be or include one or more wired links (e.g., an electrical link, an optical fiber link) or one or more wireless links (e.g., a radio link, a wireless optical link), among other examples or various combinations thereof. A UE 115 may communicate with the core network 130 via a communication link 155.

[0060] One or more of the network entities 105 or network equipment described herein may include or may be referred to as a base station 140 (e.g., a base transceiver station, a radio base station, an NR base station, an access point, a radio transceiver, a NodeB, an eNodeB (eNB), a next-generation NodeB or giga-NodeB (either of which may be referred to as a gNB), a 5G NB, a next-generation eNB (ng-eNB), a Home NodeB, a Home eNodeB, or other suitable terminology). In some examples, a network entity 105 (e.g., a base station 140) may be implemented in an aggregated (e.g., monolithic, standalone) base station architecture, which may be configured to utilize a protocol stack that is physically or logically integrated within one network entity (e.g., a network entity 105 or a single RAN node, such as a base station 140).

[0061] In some examples, a network entity 105 may be implemented in a disaggregated architecture (e.g., a disaggregated base station architecture, a disaggregated RAN architecture), which may be configured to utilize a protocol stackthat is physically or logically distributed among multiple network entities (e g., network entities 105), such as an integrated access and backhaul (IAB) network, an open RAN (O-RAN) (e.g., a network configuration sponsored by the O-RAN Alliance), or a virtualized RAN (vRAN) (e.g., a cloud RAN (C-RAN)). For example, a network entity- 105 may include one or more of a central unit (CU), such as a CU 160, a distributed unit (DU), such as a DU 165, a radio unit (RU), such as an RU 170, a RAN Intelligent Controller (RIC), such as an RIC 175 (e.g., a Near-Real Time RIC (Near-RT RIC), a Non-Real Time RIC (Non-RT RIC)), a Service Management and Orchestration (SMO) system, such as an SMO system 180, or any combination thereof. An RU 170 may also be referred to as a radio head, a smart radio head, a remote radio head (RRH), a remote radio unit (RRU), or a transmission reception point (TRP). One or more components of the network entities 105 in a disaggregated RAN architecture may be co-located, or one or more components of the network entities 105 may be located in distributed locations (e.g., separate physical locations). In some examples, one or more of the network entities 105 of a disaggregated RAN architecture may be implemented as virtual units (e.g., a virtual CU (VCU), a virtual DU (VDU), a virtual RU (VRU)).

[0062] The split of functionality between a CU 160. a DU 165, and an RU 170 is flexible and may support different functionalities depending on which functions (e.g., network layer functions, protocol layer functions, baseband functions, RF functions, or any combinations thereof) are performed at a CU 160, a DU 165, or an RU 170. For example, a functional split of a protocol stack may be employed between a CU 1 0 and a DU 165 such that the CU 160 may support one or more layers of the protocol stack and the DU 165 may support one or more different layers of the protocol stack. In some examples, the CU 160 may host upper protocol layer (e.g., layer 3 (L3), layer 2 (L2)) functionality and signaling (e.g., Radio Resource Control (RRC), sendee data adaptation protocol (SDAP), Packet Data Convergence Protocol (PDCP)). The CU 160 (e.g., one or more CUs) may be connected to a DU 165 (e.g., one or more DUs) or an RU 170 (e.g., one or more RUs), or some combination thereof, and the DUs 165, RUs 170, or both may host lower protocol layers, such as layer 1 (LI) (e.g., physical (PHY) layer) or L2 (e.g., radio link control (RLC) layer, medium access control (MAC) layer) functionality and signaling, and may each be at least partially controlled by the CU 160. Additionally, or alternatively, a functional split of the protocol stack may be employedbetween a DU 165 and an RU 170 such that the DU 165 may support one or more layers of the protocol stack and the RU 170 may support one or more different layers of the protocol stack. The DU 165 may support one or multiple different cells (e.g., via one or multiple different RUs, such as an RU 170). In some cases, a functional split between a CU 160 and a DU 165 or between a DU 165 and an RU 170 may be within a protocol layer (e.g., some functions for a protocol layer may be performed by one of a CU 160, a DU 165, or an RU 170, while other functions of the protocol layer are performed by a different one of the CU 160, the DU 165, or the RU 170). A CU 160 may be functionally split further into CU control plane (CU-CP) and CU user plane (CU-UP) functions. A CU 160 may be connected to a DU 165 via a midhaul communication link 162 (e.g., Fl, Fl-c, Fl-u), and a DU 165 may be connected to an RU 170 via a fronthaul communication link 168 (e.g., open fronthaul (FH) interface). In some examples, a midhaul communication link 162 or a fronthaul communication link 168 may be implemented in accordance with an interface (e.g., a channel) between layers of a protocol stack supported by respective network entities (e.g., one or more of the network entities 105) that are in communication via such communication links.

[0063] In some wireless communications systems (e.g., the wireless communications system 100), infrastructure and spectral resources for radio access may support wireless backhaul link capabilities to supplement wired backhaul connections, providing an IAB network architecture (e.g., to a core network 130). In some cases, in an IAB network, one or more of the network entities 105 (e.g., network entities 105 or IAB node(s) 104) may be partially controlled by each other. The IAB node(s) 104 may be referred to as a donor entity or an IAB donor. A DU 165 or an RU 170 may be partially controlled by a CU 160 associated with a network entity 105 or base station 140 (such as a donor network entity or a donor base station). The one or more donor entities (e.g., IAB donors) may be in communication with one or more additional devices (e.g.. IAB node(s) 104) via supported access and backhaul links (e.g., backhaul communication link(s) 120). IAB node(s) 104 may include an IAB mobile termination (IAB-MT) controlled (e.g., scheduled) by one or more DUs (e.g., DUs 165) of a coupled IAB donor. An IAB-MT may be equipped with an independent set of antennas for relay of communications with UEs 115 or may share the same antennas (e.g., of an RU 170) of IAB node(s) 104 used for access via the DU 165 of the IAB node(s) 104 (e.g..referred to as virtual IAB-MT (vIAB-MT)). In some examples, the IAB node(s) 104 may include one or more DUs (e.g., DUs 165) that support communication links with additional entities (e.g., IAB node(s) 104, UEs 115) within the relay chain or configuration of the access network (e.g., downstream). In such cases, one or more components of the disaggregated RAN architecture (e.g., the IAB node(s) 104 or components of the IAB node(s) 104) may be configured to operate according to the techniques described herein.

[0064] In the case of the techniques described herein applied in the context of a disaggregated RAN architecture, one or more components of the disaggregated RAN architecture may be configured to support test as described herein. For example, some operations described as being performed by a UE 115 or a network entity 105 (e.g., a base station 140) may additionally, or alternatively, be performed by one or more components of the disaggregated RAN architecture (e.g., components such as an IAB node, a DU 165, a CU 160, an RU 170, an RIC 175, an SMO system 180).

[0065] A UE 115 may include or may be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable terminology7, where the “device'’ may also be referred to as a unit, a station, a terminal, or a client, among other examples. A UE 115 may also include or may be referred to as a personal electronic device such as a cellular phone, a personal digital assistant (PDA), a tablet computer, a laptop computer, or a personal computer. In some examples, a UE 115 may include or be referred to as a wireless local loop (WLL) station, an Internet of Things (loT) device, an Internet of Everything (loE) device, or a machine type communications (MTC) device, among other examples, which may be implemented in various objects such as appliances, vehicles, or meters, among other examples.

[0066] The UEs 115 described herein may be able to communicate with various types of devices, such as UEs 115 that may sometimes operate as relays, as well as the network entities 105 and the network equipment including macro eNBs or gNBs. small cell eNBs or gNBs, or relay base stations, among other examples, as shown in FIG. 1.

[0067] The UEs 115 and the network entities 105 may wirelessly communicate with one another via the communication link(s) 125 (e.g., one or more access links) usingresources associated with one or more carriers. The term ‘'carrier” may refer to a set of RF spectrum resources having a defined PHY layer structure for supporting the communication link(s) 125. For example, a carrier used for the communication link(s) 125 may include a portion of an RF spectrum band (e.g., a bandwidth part (BWP)) that is operated according to one or more PHY layer channels for a given RAT (e.g., LTE, LTE-A, LTE-A Pro, NR). Each PHY layer channel may cany7acquisition signaling (e.g., synchronization signals, system information), control signaling that coordinates operation for the carrier, user data, or other signaling. The wireless communications system 100 may support communication with a UE 115 using carrier aggregation or multi-carrier operation. A UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration. Carrier aggregation may be used with both frequency division duplexing (FDD) and time division duplexing (TDD) component carriers. Communication between a network entity 105 and other devices may refer to communication between the devices and any portion (e.g., entity, sub-entity) of a network entity 105. For example, the terms “transmitting,” “receiving,” or “communicating,” when referring to a network entity 105, may refer to any portion of a network entity 105 (e.g., a base station 140, a CU 160, a DU 165, a RU 170) of a RAN communicating with another device (e.g., directly or via one or more other network entities, such as one or more of the network entities 105).

[0068] Signal waveforms transmitted via a carrier may be made up of multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)). In a system employing MCM techniques, a resource element may refer to resources of one symbol period (e.g., a duration of one modulation symbol) and one subcarrier, in which case the symbol period and subcarrier spacing may be inversely related. The quantity of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both), such that a relatively higher quantity of resource elements (e.g., in a transmission duration) and a relatively higher order of a modulation scheme may correspond to a relatively higher rate of communication. A wireless communications resource may refer to a combination of an RF spectrum resource, atime resource, and a spatial resource (e.g., a spatial layer, a beam), and the use of multiple spatial resources may increase the data rate or data integrity for communications with a UE 115.

[0069] The time intervals for the network entities 105 or the UEs 115 may be expressed in multiples of a basic time unit which may, for example, refer to a sampling period of Ts= l / ( fmax■seconds, for which fmaxmay represent a supported subcarrier spacing, and Nf may represent a supported discrete Fourier transform (DFT) size. Time intervals of a communications resource may be organized according to radio frames each having a specified duration (e.g., 10 milliseconds (ms)). Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023).

[0070] Each frame may include multiple consecutively-numbered subframes or slots, and each subframe or slot may have the same duration. In some examples, a frame may be divided (e.g., in the time domain) into subframes, and each subframe may be further divided into a quantity of slots. Alternatively, each frame may include a variable quantity of slots, and the quantity of slots may depend on subcarrier spacing. Each slot may include a quantity of symbol periods (e.g., depending on the length of the cyclic prefix prepended to each symbol period). In some wireless communications systems, such as the wireless communications system 100, a slot may further be divided into multiple mini-slots associated with one or more symbols. Excluding the cyclic prefix, each symbol period may be associated with one or more (e.g.. Ay) sampling periods. The duration of a symbol period may depend on the subcarrier spacing or frequency band of operation.

[0071] A subframe, a slot, a mini-slot, or a symbol may be the smallest scheduling unit (e.g., in the time domain) of the wireless communications system 100 and may be referred to as a transmission time interval (TTI). In some examples, the TTI duration (e.g., a quantity' of symbol periods in a TTI) may be variable. Additionally, or alternatively, the smallest scheduling unit of the wireless communications system 100 may be dynamically selected (e.g., in bursts of shortened TTIs (sTTIs)).

[0072] Physical channels may be multiplexed for communication using a carrier according to various techniques. A physical control channel and a physical data channel may be multiplexed for signaling via a downlink carrier, for example, using one or moreof time division multiplexing (TDM) techniques, frequency division multiplexing (FDM) techniques, or hybrid TDM-FDM techniques. A control region (e.g., a control resource set (CORESET)) for a physical control channel may be defined by a set of symbol periods and may extend across the system bandwidth or a subset of the system bandwidth of the carrier. One or more control regions (e.g., CORESETs) may be configured for a set of the UEs 115. For example, one or more of the UEs 115 may monitor or search control regions for control information according to one or more search space sets, and each search space set may include one or multiple control channel candidates in one or more aggregation levels arranged in a cascaded manner. An aggregation level for a control channel candidate may refer to an amount of control channel resources (e.g., control channel elements (CCEs)) associated with encoded information for a control information format having a given payload size. Search space sets may include common search space sets configured for sending control information to UEs 115 (e.g., one or more UEs) or may include UE-specific search space sets for sending control information to a UE 115 (e.g., a specific UE).

[0073] The wireless communications system 100 may be configured to support ultra-reliable communications or low-latency communications, or various combinations thereof. For example, the wireless communications system 100 may be configured to support ultra-reliable low-latency communications (URLLC). The UEs 115 may be designed to support ultra-reliable, low-latency, or critical functions. Ultra-reliable communications may include private communication or group communication and may be supported by one or more services such as push-to-talk, video, or data. Support for ultra-reliable, low-latency functions may include prioritization of services, and such services may be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, and ultra-reliable low-latency may be used interchangeably herein.

[0074] In some examples, a UE 115 may be configured to support communicating directly with other UEs (e.g., one or more of the UEs 115) via a device-to-device (D2D) communication link, such as a D2D communication link 135 (e.g., in accordance with a peer-to-peer (P2P), D2D, or sidelink protocol). In some examples, one or more UEs 115 of a group that are performing D2D communications may be within the coverage area 110 of a network entity 105 (e.g., a base station 140, an RU 170). which may supportaspects of such D2D communications being configured by (e.g., scheduled by) the network entity 105. In some examples, one or more UEs 115 of such a group may be outside the coverage area 110 of a network entity 105 or may be otherwise unable to or not configured to receive transmissions from a network entity 105. In some examples, groups of the UEs 115 communicating via D2D communications may support a one-to- many (1:M) system in which each UE 115 transmits to one or more of the UEs 115 in the group. In some examples, a network entity 105 may facilitate the scheduling of resources for D2D communications. In some other examples, D2D communications may be carried out between the UEs 115 without an involvement of a network entity 105.

[0075] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity7, and other access, routing, or mobility functions. The core network 130 may be an evolved packet core (EPC) or 5G core (5GC). which may include at least one control plane entity that manages access and mobility (e g., a mobility management entity (MME), an access and mobility management function (AMF)) and at least one user plane entity that routes packets or interconnects to external networks (e.g., a serving gateway (S-GW), a Packet Data Network (PDN) gateway (P-GW). or a user plane function (UPF)). The control plane entity may manage non-access stratum (NAS) functions such as mobility, authentication, and bearer management for the UEs 115 served by the network entities 105 (e.g., base stations 140) associated with the core network 130. User IP packets may be transferred through the user plane entity, which may provide IP address allocation as well as other functions. The user plane entity may be connected to IP services 150 for one or more network operators. The IP services 150 may include access to the Internet, Intranet(s), an IP Multimedia Subsystem (IMS), or a Packet-Switched Streaming Service.

[0076] The wireless communications system 100 may operate using one or more frequency bands, which may be in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). Generally, the region from 300 MHz to 3 GHz is known as the ultra-high frequency (UHF) region or decimeter band because the wavelengths range from approximately one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features, which may be referred to asclusters, but the waves may penetrate structures sufficiently for a macro cell to provide service to the UEs 115 located indoors. Communications using UHF waves may be associated with smaller antennas and shorter ranges (e.g., less than one hundred kilometers) compared to communications using the smaller frequencies and longer waves of the high frequency (HF) or very high frequency (VHF) portion of the spectrum below 300 MHz.

[0077] The wireless communications system 100 may utilize both licensed and unlicensed RF spectrum bands. For example, the wireless communications system 100 may employ License Assisted Access (LAA), LTE-Unlicensed (LTE-U) RAT, or NR technology using an unlicensed band such as the 5 GHz industrial, scientific, and medical (ISM) band. While operating using unlicensed RF spectrum bands, devices such as the network entities 105 and the UEs 115 may employ carrier sensing for collision detection and avoidance. In some examples, operations using unlicensed bands may be based on a carrier aggregation configuration in conjunction with component carriers operating using a licensed band (e.g., LAA). Operations using unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among other examples.

[0078] A network entity 105 (e.g., a base station 140, an RU 170) or a UE 115 may be equipped with multiple antennas, which may be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. The antennas of a network entity 105 or a UE 115 may be located within one or more antenna arrays or antenna panels, which may support MIMO operations or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly, such as an antenna tower. In some examples, antennas or antenna arrays associated wi th a network entity 105 may be located at diverse geographic locations. A network entity 105 may include an antenna array with a set of rows and columns of antenna ports that the network entity 105 may use to support beamforming of communications with a UE 1 15. Likewise, a UE 115 may include one or more antenna arrays that may support various MIMO or beamforming operations. Additionally, or alternatively, an antenna panel may support RF beamforming for a signal transmitted via an antenna port.

[0079] Beamforming, which may also be referred to as spatial filtering, directional transmission, or directional reception, is a signal processing technique that may be used at a transmitting device or a receiving device (e.g., a network entity 105, a UE 115) to shape or steer an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming may be achieved by combining the signals communicated via antenna elements of an antenna array such that some signals propagating along particular orientations with respect to an antenna array experience constructive interference while others experience destructive interference. The adjustment of signals communicated via the antenna elements may include a transmitting device or a receiving device applying amplitude offsets, phase offsets, or both to signals carried via the antenna elements associated with the device. The adjustments associated with each of the antenna elements may be defined by a beamforming weight set associated with a particular orientation (e.g.. with respect to the antenna array of the transmitting device or receiving device, or with respect to some other orientation).

[0080] The UEs 115 and the network entities 105 may support retransmissions of data to increase the likelihood that data is received successfully. Hybrid automatic repeat request (HARQ) (e.g., including acknowledgements (ACKs) and negative acknowledgements (NACKs)) feedback is one technique for increasing the likelihood that data is received correctly via a communication link (e.g., the communication link(s) 125, a D2D communication link 135). HARQ may include a combination of error detection (e.g., using a cyclic redundancy check (CRC)), forward error correction (FEC), and retransmission (e.g., automatic repeat request (ARQ)). HARQ may improve throughput at the MAC layer in relatively poor radio conditions (e.g., low signal-to- noise conditions). In some examples, a device may support same-slot HARQ feedback, in which case the device may provide HARQ feedback in a specific slot for data received via a previous symbol in the slot. In some other examples, the device may provide HARQ feedback in a subsequent slot, or according to some other time interval.

[0081] In some wireless communications system, the network entity 105 may communicate with the UE 115 via SPS. For example, a netw ork entity 105 may transmit, via RRC signaling, a configuration indicating periodic SPS occasions (e.g., periodic time and frequency resources). The network entity 105 may transmit, to the UE1 15, downlink control information activating the SPS configuration, such that the UE 115 may have an indication of when to begin monitoring the SPS occasions. By using the SPS occasions, the network entity 105 may transmit PDSCH to the UE 115 without first transmitting multiple scheduling DCIs.

[0082] In some cases, a main radio of the UE 115 may enter a sleep mode (e.g., an inactive mode), where the UE 115 may power off the main radio and use a LP-WUR to monitor for a WUS. In such cases, if the SPS configuration is activated, then the UE 115 may wake-up the main radio prior to each SPS occasion, monitor the SPS occasion, and receive the PDSCH transmission. In some cases, however, one of the multiple of the periodic SPS occasions may be empty (e.g., not include a PDSCH transmission), which may cause the UE 115 to unnecessarily wake-up the main radio and monitor the SPS occasion, thereby reducing power savings at the UE 115.

[0083] The techniques described herein may enable the network entity 105 to indicate, via the WUS, whether one or more of the periodic SPS occasions will be empty (e.g., whether one or more of the multiple SPS occasions include a PDSCH transmission), thereby reducing the quantity of times at w hich the UE 115 wakes up to monitor an empty SPS occasion. For example, the UE 115 may receive, via the main radio, control signaling indicating a configuration associated the WUS and also indicating an association between the WUS and a SPS occasion (e.g.. that the WUS contains information associated with the SPS occasion). Accordingly, the UE 115 may monitor, via the LP-WUR and while the main radio is operating in the sleep mode, for the WUS, where the WUS may indicate whether the associated SPS occasion includes a PDSCH transmission. For example, the WUS may indicate that the SPS occasion does include a PDSCH transmission and, as such, the UE 115 may wake-up the main radio and monitor the SPS occasion for the PDSCH transmission. Alternatively, the WUS may indicate that the SPS occasion does not include a PDSCH transmission (e.g., is empty) and, as such, the UE 115 may not wake-up the main radio. In this way, the network entity 105 may indicate whether the SPS occasion includes a PDSCH transmission via the WUS.

[0084] FIG. 2 shows an example of a wireless communications system 200 that supports techniques to activate SPS occasions in accordance with one or more aspects of the present disclosure. Aspects of the wireless communications system 200 mayimplement, or be implemented by, aspects of wireless communications system 100 with reference to FIG. 1. For example, the wireless communications system 200 may include a network entity 105 -a and a UE 115-a, which may be examples of the network entity 105 and the UEs 115 as described herein with reference to FIG. 1. The techniques described in the context of the wireless communications system 200 may enable the network entity 105-ato indicate, via a WUS 205, whether one or more SPS occasions 210 include PDSCHs 215.

[0085] In some cases, the UE 115-a may include one or more radios. For example, the UE 115-a may utilize a main radio 202 during active communications, for example, while the UE 1 15-a is operating in an active or connected mode. The UE 115-a also may include a LP-WUR 204, which may be a companion receiver, to the main radio 202, where the LP-WUR 204 may draw a relatively lower power than the main radio 202 and be used by the UE 115-a to monitor for a WUS 205 while the main radio 202 is operating in a deep sleep state. While the main radio 202 is operating in the sleep mode, the UE 115-a, via the LP-WUR 204, may monitor for the WUS 205, such that the UE 115-a may experience power savings during such operations. Accordingly, in response to receiving the WUS 205, the LP-WUR 204 may wake-up the main radio 202 (e.g., indicate to the main radio 202 to power up) to receive data communications from the network entity 105-a. In such examples, the LP-WUR may consume a relatively lower power than the main radio 202 by design, for example, the LP-WUR may be powered separately than the main radio 202, include relatively fewer components that consume power than the main radio 202, or both. By using the LP-WUR 204 while the main radio 202 is in the sleep mode, the UE 115-a may reduce the total power consumption by avoiding unnecessary wake-ups of the main radio 202, which may increase power consumption at the UE 115-a, and also reduce latency by monitoring WUSs 205.

[0086] In some examples, to facilitate downlink communication with the UE 115-a, the network entity 105-a may perform semi-persistent scheduling, where the network entity 105-a may configure one or more SPS occasions 210, which may be periodic resources allocated for downlink transmissions to the UE 115-a (e.g., and retransmissions may be sent via dynamic grants). For example, the network entity 105-a may transmit control signaling 220 (e.g., RRC signaling) that includes an SPS configuration, where the SPS configuration indicates a periodicity of the SPS occasions210, a quantity of RBs associated with the SPS occasions 210, a modulation and coding scheme (MCS) associated with the SPS occasion 210, physical uplink control channel (PUCCH) resources for HARQ-ACK feedback associated with the SPS occasions 210, or a combination thereof. That is, the network entity 105-a may indicate, via the control signaling 220, the same periodicity and parameters for each SPS occasion 210 in the SPS configuration.

[0087] In such examples, the network entity 105-a may activate the SPS configuration indicated by the control signaling 220 via downlink control information (DCI) 230 included in a physical downlink control channel (PDCCH) 225. In such examples, the DCI 230 may also re-indicate, or update, the SPS configuration, for example, by indicating the time-frequency resources and aforementioned parameters associated with the SPS occasions 210 (in a similar way as dynamic scheduling). Based on receiving the control signaling 220 indicating the SPS configuration and the DCI 230 activating the SPS configuration, the UE 115-a may monitor, via the main radio 202. each SPS occasion 210 to receive PDSCHs 215.

[0088] In some cases, however, one of the configured SPS occasions 210 may not carry a PDSCH 215. That is, the network entity 105-a may transmit aperiodic downlink data (e.g., aperiodic PDSCH transmissions) using the SPS occasions 210. resulting in some SPS occasions 210 being empty (e.g., not carrying a PDSCH 215). For example, the network entity 105-a may transmit a PDSCH 215-a via the SPS occasion 210-a and transmit a PDSCH 215-b of the SPS occasion 210-b, but refrain from transmitting downlink data via the SPS occasion 210-c, resulting in the SPS occasion 210-c. Such aperiodic downlink transmissions may occur during extended reality (XR) communications, where the periodicity of XR application data may not match with the periodicity of the SPS occasions 210, where the arrival times of the XR application data may vary due to jitter (e.g., latency) in the communication flow between the XR server and the UE 115-a, or both.

[0089] Such empty SPS occasions 210 may lead to a decrease in power savings at the UE 115-a. For example, the UE 115-a may receive the WUS 205 indicating for the UE 115-a to wake-up the main radio 202 and monitor for the DCI 230 activating an SPS configuration. How ever, if one or more of the SPS occasions 210 are empty (e.g., do not include a PDSCH 215), the UE 115-a may unnecessarily wake-up the main radio 202and monitor the empty SPS occasion 210-c, thereby reducing power savings at the UE 115-a. Thus, techniques may be desired to reduce the quantity of times the UE 115-a wakes-up the main radio 202 to monitor empty SPS occasions 210.

[0090] Further, in some cases, activating the SPS configuration via the DCI 230 may increase the overhead between the UE 115-a and the network entity 105-a. For example, if the channel conditions between the UE 115-a and the network entity 105-a remain static (e.g., do not change), the network entity 105-a may unnecessarily update the SPS configuration via the DCI 230 (e.g., update the quantity of RBs of the SPS occasions 210, update the MCS of the SPS occasions 210, update the PUCCH resources associated with the SPS occasions 210). That is, the functionality of scheduling and activating the SPS configuration via the DCI 230 of the PDCCH 225 may be unnecessary under static channel conditions. Thus, techniques may be desired to reduce the overhead between the UE 115-a and the network entity 105-a due to transmitting the DCI 230 activating the SPS configuration.

[0091] The techniques described herein may enable the network entity 105-a to perform SPS activation via the WUS 205, thereby reducing the overhead between the UE 115-a and the network entity 105-a, and also enable the network entity 105-a to indicate, via the WUS 205, whether one or more SPS occasions 210 include PDSCHs 215 (e.g.. whether the SPS occasions 210 are empty), thereby increasing power savings at the UE 115-a. For example, if the traffic (e.g., data communication) between the UE 115-a and the network entity 105-a is relatively low (e.g., light) or if the traffic between the UE 115-a and the network entity 105-a includes aperiodic data, such as XR communications, the UE 115-a may skip monitoring one or more SPS occasions 210 that do not carry a PDSCH 215, skip monitoring the DCI 230 that activates the one or more SPS occasions 210 that do not carry a PDSCH 215, or both, in response to receiving an indication via the WUS 205, thereby saving power at the UE 115-a.

[0092] In some examples, the network entity 105-a may configure one or more multiple sets of WUSs 205 to be associated with (e.g., be received prior to and contain information for) the SPS occasions 210. For example, the network entity 105-a may transmit, via the control signaling 220 and in addition to the SPS configuration, a configuration associated with the WUS 205. In such examples, the network entity 105-a may indicate, via the configuration, time and frequency resources for the WUS 205,indicate an association between the WUS 205 and the SPS occasions 210, indicate waveform parameters associated with the WUS 205, indicate sequence parameters associated with the WUS 205, or a combination thereof.

[0093] In such examples, the network entity 105-a may set the periodicity of the WUS 205 based on the periodicity indicated in the SPS configuration for the SPS occasions 210, for example, by setting the periodicity of the WUS 205 to be multiple times that of the periodicity indicated by the SPS configuration for the SPS occasions 210. Similarly, the network entity 105-a may set the time offset of the WUS 205 based on the SPS configuration for the SPS occasions, for example, by setting the time offset of the WUS 205 relative to the starting slot of the SPS occasion 210-a (e.g., first SPS occasion 210 of the SPS configuration).

[0094] As an illustrative example, the network entity 105-a may indicate the configuration for the WUS 205 and also indicate that the WUS 205 includes information associated with each SPS occasion 210 (e.g., the SPS occasion 210-a, the SPS occasion 210-b, the SPS occasion 210-c) of an SPS configuration. Alternatively, the network entity 105-a may indicate a configuration for a first WUS 205 and indicate that the first WUS 205 includes information for the SPS occasion 210-a, indicate a configuration for a second WUS 205 and indicate that the second WUS 205 includes information for the SPS occasion 210-b and the SPS occasion 210-c. In some other examples, the network entity’ 105-a may configure a respective WUS 205 (e.g., transmit respective configurations via the control signaling 220) for each SPS occasion 210. In such examples, the network entity 105-a may set the periodicity and time offset of the WUS 205 to be based on those of the SPS configuration of the SPS occasions 210.

[0095] Accordingly, while the main radio 202 is operating in the sleep mode, the UE 1 15-a may monitor, using the LP-WUR 204, for the WUS 205 according to the configuration indicated via the control signaling 220, where the WUS 205 may provide an indication from the network entity 105-a as to whether one or more SPS occasions 210 (e.g.. whether the group of SPS occasions 210 or a single SPS occasion 210) includes PDSCH 215. As such, if the WUS 205 indicates that the SPS occasions 210 are empty (e.g., do not include a PDSCH 215), the UE 115-a may refrain from aking up the main radio 202 and maintain the main radio 202 in the sleep mode, thereby- refraining from using the main radio 202 to monitor for the DCI 230 and empty SPSoccasions 210. Alternatively, if the WUS 205 indicates that one or more of the SPS occasions are not empty include a PDSCH 215, the UE 115-a may wake-up the main radio 202 to monitor for the DCI 230, receive the PDSCH 215, and decode the PDSCH 215.

[0096] As an illustrative example, the network entity 105-a may indicate, via the control signaling 220, that the WUS 205 is associated with the SPS occasion 210-a, the SPS occasion 210-b, and the SPS occasion 210-c. Accordingly, the UE 115-a may receive, via the LP-WUR 204, the WUS 205, where the WUS 205 may indicate that the SPS occasion 210-a includes the PDSCH 215-a. indicate that the SPS occasion 210-b includes the PDSCH 215-b, and indicate that the SPS occasion 210-c does not include a PDSCH 215 (e.g., is empty). Based on the WUS 205, the UE 115-a may wake-up the main radio 202, monitor for the PDCCH for the DCI 230 activating the SPS configuration associated with the SPS occasions 210, monitor the SPS occasion 210-a for the PDSCH 215-a and the SPS occasion 210-b for the PDSCH 215-b. and refrain from monitoring the SPS occasion 210-c.

[0097] In some examples, if the WUS 205 indicates that the one or more SPS occasions 210 are not empty (e.g., include a PDSCH 215), the network entity 105-a may further indicate, via the WUS 205, whether the UE 115-a is to wake-up the main radio 202 and monitor for the DCI 230. That is. because the network entity 105-a indicates that the one or more SPS occasions 210 include a PDSCH 215 via the WUS 205, the UE 115-a may refrain from receiving the activation information via the DCI 230, and accordingly, skip monitoring for the DCI 230 in order to further save power.

[0098] For example, if the channel between the UE 115-a and the network entity 105-a is stable (e.g., static, not changing) and the traffic load is static (e.g., consistent, not variable), the network entity 105-a may refrain from dynamically updating the parameters of the SPS occasions 210 (e.g., quantity of RBs for each SPS occasion 210, MCS associated with each SPS occasion, PUCCH resources for HARQ-ACK feedback associated with each SPS occasion 210). Accordingly, the network entity 105-a may transmit the WUS 205 to further indicate that the UE 115-a is to skip monitoring the DCI 230 and directly monitor the SPS occasions 210 to receive and decode the PDSCHs 215 using the previous scheduling information (e.g., SPS configuration indicated via thecontrol signaling 220 or previous DCI 230), which may further save power at the UE 115-a.

[0099] As an illustrative example, the network entity 105 -a may indicate, via the control signaling 220, that the WUS 205 is associated with the SPS occasion 210-a, the SPS occasion 210-b, and the SPS occasion 210-c. Accordingly, the UE 115-a may receive, via the LP-WUR 204, the WUS 205, where the WUS 205 may indicate that the SPS occasion 210-a includes the PDSCH 215-a, indicate that the SPS occasion 210-b includes the PDSCH 215-b, and indicate that the SPS occasion 210-c does not include a PDSCH 215 (e.g., is empty). The WUS 205 may further indicate to skip monitoring the PDCCH for the DCI 230. Based on the WUS 205, the UE 1 15-a may wake-up the main radio 202, refrain from monitoring the PDCCH for the DCI 230, monitor the SPS occasion 210-a for the PDSCH 215-a and the SPS occasion 210-b for the PDSCH 215-b, and refrain from monitoring the SPS occasion 210-c.

[0100] In some examples, if the UE 115-a does not detect the WUS 205 (e.g., does not receive the WUS 205), the UE 115-a may refrain from waking up the main radio 202 and skip monitoring the SPS occasions 210. For example, the network entity 105-a may indicate that each of the SPS occasions 210 do not include a PDSCH 215 (e.g., are empty) based on not transmitting the WUS 205. Accordingly, the UE 115-a may not receive the WUS 205 and skip monitoring the SPS occasions. Alternatively, if the UE 115-a does not detect the WUS 205, the UE 115-a may wake-up the main radio 202, monitor the SPS occasions 210, and receive the PDSCHs 215. For example, if the WUS 205 is not transmitted from the network entity 105-a, the UE 115-a may determine that the PDSCHs 215 (e.g.. downlink data) is periodic and present in the SPS occasions 210. Accordingly, the UE 1 15-a may wakeup the main radio 202, monitor the SPS occasions 210, and receive the PDSCHs 215 without first monitoring for the WUS 205.

[0101] The UE 115-a may determine whether the SPS occasions 210 includes a PDSCH 215 according to one or more bits of the WUS 205, according to a waveform of the WUS 205, according to a data rate of the WUS 205. or a combination thereof. In some examples, the WUS 205 may include one or more bits indicating whether the SPS occasions 210 include a PDSCH 215, where such bits may be the least significant bits (LSBs) of the WUS 205, while legacy information for wake-up procedures may be the most significant bits (MSBs) of the WUS 205. or vice versa. As an illustrative example,the WUS 205 may include three bits (e.g., three LSBs), where a first of the three bits may correspond to the SPS occasion 210-a, a second of the three bits may correspond to the SPS occasion 210-b, and a third of the three bits may correspond to the SPS occasion 210-c. Accordingly, the UE 115-a may determine whether each of the SPS occasions 210 include a PDSCH 215 based on the bit values of the corresponding bits (e.g., a bit value of ‘ 1 ’ indicates not empty, a bit value of ’0’ indicates empty, or vice versa). In this way, the network entity 105-a may indicate whether the SPS occasions are empty according to bits added to the WUS 205.

[0102] In some other examples, the network entity 105-a may transmit the WUS 205 according to one or more data rates (e.g., symbol rates) to indicate whether the SPS occasions 210 include a PDSCH 215. For example, several data rates (e.g., symbol rates) may be defined, such as a default data rate, a first data rate, a second data rate, a third data rate, and so on, where each data rate may correspond to a respective WUS configuration. Each WUS configuration may provide an indication as to which SPS occasion 210 is empty or not. Accordingly, if the WUS 205 is transmitted according to the default data rate (e.g., corresponding to the default WUS configuration), the UE 115-a may determine that each of the SPS occasions 210 include a PDSCH 215 or do not include a PDSCH 215. As such, if the UE 115-a does not detect a WUS 205 with the default data rate, the UE 115-a may have an indication that each status (e.g., whether empty or not) of the SPS occasion 210 is different. For example, if the UE 115-a detects that the WUS 205 has a non-default data rate, the UE 115-a may identify the associated non-default WUS configuration, which may indicate whether a specific SPS occasion 210 is empty or not.

[0103] In some other examples, the network entity 105-a may transmit the WUS 205 with a hybrid waveform (e.g., a first portion of the waveform is different from a second portion of the waveform), such as an on-off keying (OOK) and frequency modulated continuous wave (FMCW) waveform, a frequency shift keying (FSK) and FMCW waveform, an OOK waveform with an FMCW slope, or an FSK waveform with an FMCW slope. To produce such waveforms, the network entity7105-a may modulate the WUS 205 according to a combination of MCSs (e.g., to produce the OOK FMCW waveform, the network entity 105-a may apply an OOK MCS and FMCW MCS to transmit the WUS 205). Accordingly, the UE 115-a may determine whether one or moreSPS occasions 210 include a PDSCH 215 based on the hybrid waveform of the WUS 205. For example, if the UE 115 -a detects a first waveform (e.g., a default waveform), then the UE 115-a may determine that each of the SPS occasions 210 include a PDSCH 215 or do not include a PDSCH 215. Alternatively, if the UE 115-a does not detect a WUS 205 (e.g., a default waveform), the UE 115-a may combine the first waveform with a second waveform to form the hybrid waveform and detect whether a specific SPS occasion 210 is empty or not based on the hybrid waveform. In such examples, if the UE 115-a does not detect a defined waveform for the WUS 205, the UE 115-a may refrain from waking up the main radio 202 and skip monitoring the SPS occasions or wake-up the main radio 202 and monitor the SPS occasions.

[0104] As described herein, the network entity 105-a may use the SPS occasions 210 to transmit XR traffic, however, the jitter associated with such XR traffic (e.g., PDSCHs 215 carrying XR data) may result in one or more of the SPS occasions 210 being empty. Accordingly, the network entity 105-a may configure one or more WUSs 205 around the SPS occasions 210 carrying the XR traffic, where the WUS 205 may enable high granularity' wake-up of the main radio 202 to achieve low latency, while maintain low power consumption with LP-WUR 204. As such, the network entity 105-a may use the WUS 205 to indicate whether one or more SPS occasions 210 carrying XR traffic or not (e.g., whether the SPS occasions are empty). Further, to reduce power consumption at the UE 115-a, the network entity 105-a may transmit, via the control signaling 220, jitter range information (e.g., average arrival time of XR traffic relative to a delivery deadline, a time period prior to the average arrival time, a time period after the average arrival time) associated with the XR traffic, such that the UE 115-a may monitor for WUSs 205 that are within the jitter range of the SPS occasions 210.

[0105] In some examples, to reduce unnecessary HARQ-ACK transmissions from the UE 115-a, the UE 115-a may refrain from transmitting HARQ information based on the WUS 205. For example, if the WUS 205 indicates that the SPS occasions 210 do not include a PDSCH 215, then the UE 115-a may refrain from transmitting a NACK for the associated SPS occasions, at least if the HARQ-ACK information is the singular uplink transmission (e.g., only uplink transmission). Otherwise, the UE 115-a may utilize the PUCCH resources in the SPS configuration for HARQ-ACK transmissions when the SPS occasions 210 include a PDSCH 215.

[0106] In some other examples, the UE 115-a may determine whether to monitor for a retransmission of a PDSCH 215 based on the WUS 205. For example, the UE 115-a may determine whether to monitor for a retransmission of a PDSCH 215 original scheduled in the SPS occasions 210 based on whether the WUS 205 indicates the presence or absence of the PDSCH in the SPS occasions 210. If the WUS 205 indicates that the SPS occasions 210 are empty, then the UE 115-a may refrain from monitoring for retransmissions. Otherwise, if the UE 115-a receives an indication that the SPS occasions 210 include a PDSCH 215, the UE 115-a may also receive an indication in the WUS 205 as to whether the UE 115-a is to monitor for retransmissions of the PDSCH 215. For example, the WUS 205 may indicate for the UE 115-a to receive the PDSCH retransmission, indicate for the UE 115-a to receive the DCI 230 scheduling the PDSCH retransmission, or both.

[0107] FIG. 3 shows an example of a process flow 300 that supports techniques to activate SPS occasions in accordance with one or more aspects of the present disclosure. Aspects of the process flow 300 may implement, or be implemented by, aspects of wireless communications system 100 and the wireless communications system 200, as described herein with reference to FIGs. 1 and 2. For example, the process flow 300 may include a network entity 105-b and a UE 115-b, which may be examples of the network entity 105 and the UEs 115 as described herein with reference to FIGs. 1 and 2. The techniques described in the context of the process flow 300 may enable the network entity 105-b to indicate, via a WUS, whether one or more SPS occasions include PDSCH transmissions.

[0108] At 305, the UE 115-b may receive, via a first radio (e.g., the main radio 202), control signaling (e.g., the control signaling 220) indicating a configuration associated with a WUS (e.g., the WUS 205) and indicating an association between the WUS and a SPS occasion (e.g., SPS occasion 210). For example, the UE 115-b may receive the control signaling in accordance with the techniques described herein with reference to FIG. 2. In such examples, the configuration associated with the WUS may include time and frequency resources associated with the WUS, waveform parameters associated with the WUS (e.g., waveform ty pe, MCS, data rate, or a combination thereof), sequence parameters associated with the WUS (e.g., a quantity' of bitsassociated with the WUS), a data rate associated with the WUS, or any combination thereof.

[0109] At 310, the UE 115-b may monitor for, and receive, via a second radio (e.g., LP-WUR 204), the WUS, where the WUS indicates whether the SPS occasion includes a PDSCH (e.g., PDSCH 215). The network entity 105-b may indicate, via the WUS, whether the SPS occasion includes a PDSCH via one or more bits, via a data rate of a symbol of the WUS, a waveform of the WUS, or a combination thereof, as described herein with reference to FIG. 2. Accordingly, the UE 115-b may perform one of a first procedure (e.g., wakeup the main radio and receive PDSCH) or a second procedure (e.g., maintain the main radio in the sleep mode) based on the indication in the WUS.

[0110] At 315, if the WUS indicates that the SPS occasion does not include a PDSCH (e.g., is empty), the UE 115-b may maintain the main radio in the sleep mode and refrain from waking-up the first radio. Alternatively, at 320, if the WUS indicates that the SPS occasion does include a PDSCH, the UE 115-b may wake-up the first radio. At 325, the UE 115-b may monitor the SPS occasion and receive the PDSCH. In some examples, prior to monitoring for the SPS occasion, the UE 1 15-b may monitor a PDCCH for a DCI (e.g., DCI 230) that activates the SPS occasion, where receiving the PDSCH is based on receiving the DCI. Alternatively, the WUS may indicate for the UE 115-b to skip monitoring the DCI. and instead monitor the SPS occasion directly to receive the PDSCH.

[0117] In some examples, the communications manager 420 may be configured to perform various operations (e.g.. receiving, obtaining, monitoring, outputting, transmitting) using or otherwise in cooperation with the receiver 410. the transmitter 415, or both.

[0136] In some examples, the WUR component 630 is capable of, configured to. or operable to support a means for performing the second procedure based on an absence of the WUS during resources associated with the WUS, where the absence of the WUS during the resources indicates that the SPS occasion does not include a PDSCH.

Subsequent reference to a component introduced with the article “a” using the terms “the” or “said” may refer to any or all of the one or more components. For example, a component introduced with the article “a” may be understood to mean “one or more components.” and referring to “the component” subsequently in the claims may be understood to be equivalent to referring to “at least one of the one or morecomponents.” Similarly, subsequent reference to a component introduced as ‘'one or more components” using the terms “the” or “said” may refer to any or all of the one or more components. For example, referring to “the one or more components” subsequently in the claims may be understood to be equivalent to referring to “at least one of the one or more components.”

[0248] The term “determine” or “determining” encompasses a variety of actions and, therefore, “determining” can include calculating, computing, processing, deriving, investigating, looking up (such as via looking up in a table, a database, or another data structure), ascertaining, and the like. Also, “determining” can include receiving (e.g.. receiving information), accessing (e.g., accessing data stored in memory), and the like. Also, “determining” can include resolving, obtaining, selecting, choosing, establishing, and other such similar actions.

[0249] In the appended figures, similar components or features may have the same reference label. Further, various components of the same type may be distinguished by following the reference label by a dash and a second label that distinguishes among the similar components.
