[0034] In some wireless communications systems, a user equipment (UE) may operate in a discontinuous reception (DRX) mode, in which the UE may transition between sleep and wake modes, referred to as OFF and ON durations, respectively. If a network entity has data to communicate to the UE, the network entity may transmit a wake-up signal (WUS) to “wake” the UE (e.g., trigger the UE to transition to the wake mode) for transmission and reception of subsequent communications. In some examples, the UE may perform beam sweeping, in which the UE may “sweep” across multiple beams by transmitting and / or receiving signals using each beam to identify the correct beam to use for reception of a WUS. Such beam sweeping increases power consumption and latency.
[0035] The UE may monitor for a WUS from a network entity via one or more WUS monitoring occasions, which may include time and frequency resources via which the network entity may transmit a WUS. The WUS monitoring occasions may span across one or more DRX cycles of the UE. For example, the UE may monitor a set of one or more WUS monitoring occasions prior to each DRX cycle. In some systems, the network entity may indicate, via a first WUS in a first WUS monitoring occasion before a first DRX cycle, information regarding subsequent WUS monitoring occasions of subsequent DRX cycles. The information may indicate a configuration for the UE to use to monitor for and receive the subsequent WUSs, such as transmission configuration indication (TCI) state information, search space set ID information, or the like. However, if the UE does not receive the first WUS, behaviors for the UE to follow for subsequent WUS monitoring occasions may not be defined, which may reduce coordination between devices, may reduce throughput, and may increase latency.
[0036] The techniques, methods, and devices described herein may enable signaling for a network entity to indicate, to a UE, actions for the UE to take in subsequent WUS monitoring occasions for subsequent DRX cycles if the UE does not receive or decode a first WUS associated with a first DRX cycle. For example, the network entity may transmit the signaling (e.g., radio resource control (RRC) , downlink control information (DCI) , or a combination thereof) including one or more parameters that indicate a WUS monitoring protocol (behavior) for the UE to follow for some quantity of one or more subsequent WUS monitoring occasions across one or more DRX cycles. The signaling may indicate a monitoring protocol from two or more monitoring protocols supported by the UE for use when a WUS is not received. The first protocol may indicate for a UE to monitor all search space sets (e.g., using beam sweeping) included in subsequent WUS monitoring occasions in one or more DRX cycles. The second protocol may indicate for the UE to only monitor a single search space set (e.g., and corresponding beam) within one or more DRX cycles, where the single search space set is indicated via a WUS received in a DRX cycle before the one or more DRX cycles. The signaling may thereby clearly define UE behaviors for monitoring for and receiving a WUS in the event of a WUS detection failure.
[0037] Aspects of the disclosure are initially described in the context of wireless communications systems. Aspects of the disclosure are further described in the context of communication timelines and process flows. Aspects of the disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flowcharts that relate to control signaling for failed wake-up signal detection operations.
[0038] FIG. 1 shows an example of a wireless communications system 100 that supports control signaling for failed wake-up signal detection operations 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.
[0039] The network entities 105 may be dispersed throughout a geographic area to form the wireless communications system 100 and may include devices in different forms 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) .
[0040] 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 types 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.
[0041] 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, or the like being a node. For example, disclosure that a UE 115 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.
[0042] 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 S1, 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 between 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.
[0043] 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) .
[0044] 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 stack that 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) ) .
[0045] 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 160 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., RRC, service 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 (L1) (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 employed between 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., F1, F1-c, F1-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.
[0046] 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.
[0047] 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) .
[0048] 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 terminology, 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 (IoT) device, an Internet of Everything (IoE) 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.
[0049] 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.
[0050] 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) using resources 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 carry acquisition 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) .
[0051] 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, a time 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.
[0052] 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=1 / (Δfmax·Nf) seconds, for which Δfmax may 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) .
[0053] 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., Nf) sampling periods. The duration of a symbol period may depend on the subcarrier spacing or frequency band of operation.
[0054] 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) ) .
[0055] 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 more of 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) .
[0056] In some examples, a network entity 105 (e.g., a base station 140, an RU 170) may be movable and therefore provide communication coverage for a moving coverage area, such as the coverage area 110. In some examples, coverage areas 110 (e.g., different coverage areas) associated with different technologies may overlap, but the coverage areas 110 (e.g., different coverage areas) may be supported by the same network entity (e.g., a network entity 105) . In some other examples, overlapping coverage areas, such as a coverage area 110, associated with different technologies may be supported by different network entities (e.g., the network entities 105) . The wireless communications system 100 may include, for example, a heterogeneous network in which different types of the network entities 105 support communications for coverage areas 110 (e.g., different coverage areas) using the same or different RATs.
[0057] 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.
[0058] 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 support aspects 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.
[0059] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, 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.
[0060] 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 as clusters, 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.
[0061] 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.
[0062] 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 with 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 115. 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.
[0063] 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) .
[0064] A network entity 105 or a UE 115 may use beam sweeping techniques as part of beamforming operations. For example, a network entity 105 (e.g., a base station 140, an RU 170) may use multiple antennas or antenna arrays (e.g., antenna panels) to conduct beamforming operations for directional communications with a UE 115. Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted by a network entity 105 multiple times along different directions. For example, the network entity 105 may transmit a signal according to different beamforming weight sets associated with different directions of transmission. Transmissions along different beam directions may be used to identify (e.g., by a transmitting device, such as a network entity 105, or by a receiving device, such as a UE 115) a beam direction for later transmission or reception by the network entity 105.
[0065] Some signals, such as data signals associated with a particular receiving device, may be transmitted by a transmitting device (e.g., a network entity 105 or a UE 115) along a single beam direction (e.g., a direction associated with the receiving device, such as another network entity 105 or UE 115) . In some examples, the beam direction associated with transmissions along a single beam direction may be determined based on a signal that was transmitted along one or more beam directions. For example, a UE 115 may receive one or more of the signals transmitted by the network entity 105 along different directions and may report to the network entity 105 an indication of the signal that the UE 115 received with a highest signal quality or an otherwise acceptable signal quality.
[0066] In some examples, transmissions by a device (e.g., by a network entity 105 or a UE 115) may be performed using multiple beam directions, and the device may use a combination of digital precoding or beamforming to generate a combined beam for transmission (e.g., from a network entity 105 to a UE 115) . The UE 115 may report feedback that indicates precoding weights for one or more beam directions, and the feedback may correspond to a configured set of beams across a system bandwidth or one or more sub-bands. The network entity 105 may transmit a reference signal (e.g., a cell-specific reference signal (CRS) , a channel state information reference signal (CSI-RS) ) , which may be precoded or unprecoded. The UE 115 may provide feedback for beam selection, which may be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., a multi-panel type codebook, a linear combination type codebook, a port selection type codebook) . Although these techniques are described with reference to signals transmitted along one or more directions by a network entity 105 (e.g., a base station 140, an RU 170) , a UE 115 may employ similar techniques for transmitting signals multiple times along different directions (e.g., for identifying a beam direction for subsequent transmission or reception by the UE 115) or for transmitting a signal along a single direction (e.g., for transmitting data to a receiving device) .
[0067] A receiving device (e.g., a UE 115) may perform reception operations in accordance with multiple receive configurations (e.g., directional listening) when receiving various signals from a transmitting device (e.g., a network entity 105) , such as synchronization signals, reference signals, beam selection signals, or other control signals. For example, a receiving device may perform reception in accordance with multiple receive directions by receiving via different antenna subarrays, by processing received signals according to different antenna subarrays, by receiving according to different receive beamforming weight sets (e.g., different directional listening weight sets) applied to signals received at multiple antenna elements of an antenna array, or by processing received signals according to different receive beamforming weight sets applied to signals received at multiple antenna elements of an antenna array, any of which may be referred to as “listening” according to different receive configurations or receive directions. In some examples, a receiving device may use a single receive configuration to receive along a single beam direction (e.g., when receiving a data signal) . The single receive configuration may be aligned along a beam direction determined based on listening according to different receive configuration directions (e.g., a beam direction determined to have a highest signal strength, highest signal-to-noise ratio (SNR) , or otherwise acceptable signal quality based on listening according to multiple beam directions) .
[0068] The techniques described herein may enable signaling for the network entity 105 to indicate, to the UE 115, actions for the UE 115 to perform in subsequent WUS monitoring occasions for subsequent DRX cycles if the UE 115 does not receive or decode a first WUS associated with a first DRX cycle. For example, the network entity 105 may transmit the signaling (e.g., RRC, DCI, or a combination thereof) including one or more parameters that may indicate a WUS monitoring protocol (behavior) for the UE to follow for some quantity of one or more subsequent WUS monitoring occasions across one or more DRX cycles. The signaling may indicate a monitoring protocol from two or more monitoring protocols supported by the UE 115 for use when a WUS is not received. The first protocol may indicate for the UE 115 to monitor all search space sets (e.g., using beam sweeping) included in subsequent WUS monitoring occasions in one or more DRX cycles. The second protocol may indicate for the UE 115 to only monitor a single search space set (e.g., and corresponding beam) within one or more DRX cycles, where the single search space set is indicated via a WUS received in a DRX cycle before the one or more DRX cycles. The signaling may thereby clearly define UE 115 behaviors for monitoring for and receiving a WUS in the event of a WUS detection failure.
[0069] FIG. 2 shows an example of a communication timeline 200 that supports WUS monitoring behaviors for a UE to follow in accordance with one or more aspects of the present disclosure. The communication timeline 200 may implement or be implemented by aspects of the wireless communications system 100 described with reference to FIG. 1. For example, the communication timeline 200 may support signaling techniques for WUS transmissions and receptions between a UE 115 and a network entity 105 which may represent examples of a UE 115 and a network entity 105 as described with reference to FIG. 1, that include one or more parameters that indicate a WUS monitoring behavior (protocol) for the UE 115 to follow. By indicating a WUS protocol, the UE 115 and network entity 105 may promote more efficient coordination between devices and may improve latency.
[0070] In some cases, the UE 115 may be configured with one or more WUS monitoring occasions 205 to monitor for transmissions of a wake-up signal (WUS) 235. Each WUS monitoring occasion in the one or more WUS monitoring occasions 205 may include time and frequency resources via which the network entity 105 may transmit the WUS 260. For example, the one or more WUS monitoring occasions 205 may span across one or more DRX cycles of the UE 115, in which the UE 115 may transition between sleep and wake modes, referred to as OFF and ON durations. Each monitoring occasion may be associated with a respective search space set, a respective TCI state, a respective beam, or the like in which the UE 115 may use to monitor for the WUS 260. The UE 115 may monitor each monitoring occasion in the set of the one or more WUS monitoring occasions 205 using a different set of parameters including respective search space sets, respective TCI states, respective beams, or the like.
[0071] Some WUSs 260 may include information that may indicate parameters for monitoring subsequent sets of WUS monitoring occasions 205 in subsequent DRX cycles. The parameters may include a respective search space set, a respective TCI state, a respective beam, or any combination thereof. For example, the UE 115 may detect a first WUS 260 in a first DRX cycle 215, during an associated DRX ON duration 235. If the UE 115 fails to detect a second WUS 260 in the subsequent second DRX cycle 220, during the associated DRX ON duration 245, then the UE may utilize the parameters indicated in the first WUS 260 to monitor subsequent sets of WUS monitoring occasions, such as 205-a, 205-b, 205-c, and 205-d.
[0072] However, if the UE does not receive the first WUS 260, behaviors for the UE 115 to follow for subsequent WUS monitoring occasions 205 may not be defined, in some cases. Thus, the UE 115 may monitor either all subsequent WUS monitoring occasions 205 or none of the subsequent WUS monitoring occasions 205, but the network entity 105 may not be aware of which behavior the UE 115 will follow, which may reduce coordination between devices, may reduce throughput, and may increase latency.
[0073] The various aspects described herein may enable the UE 115 to receive control signaling 210 from the network entity 105 that may indicate actions for the UE to perform in subsequent WUS monitoring occasions 205 for subsequent DRX cycles if the UE does not receive or decode a WUS 260 associated with a DRX cycle. For example, the network entity 105 may transmit control signaling 210 (e.g., RRC, DCI, or a combination thereof) that indicates a WUS monitoring protocol (e.g., behavior, set of rules) for the UE 115 to follow for some quantity of one or more subsequent WUS monitoring occasions across one or more DRX cycles if the UE 115 does not receive a WUS. The control signaling 210 may indicate the monitoring protocol selected from two or more monitoring protocols supported by the UE 115 for use when a WUS 260 is not detected.
[0074] A first protocol of the two or more candidate protocols may indicate for the UE 115 to monitor all search space sets (e.g., using beam sweeping) included in subsequent sets of WUS monitoring occasions 205 in one or more DRX cycles. That is, the first protocol may indicate for the UE 115 to use a second set of monitoring parameters, including all beams and search space sets, to monitor for a WUS across one or more DRX cycles if the UE 115 does not receive a first WUS. A second protocol of the two or more candidate protocols may indicate for the UE 115 to only monitor a single search space set (e.g., and a corresponding beam 230-a) within one or more DRX cycles if the UE 115 does not receive a WUS, where the single search space set is indicated via a most recently received WUS 260 before the UE 115 fails to receive a next WUS. That is, the second protocol may indicate for the UE 115 to use a first set of monitoring parameters, including one or more beams, search spaces, TCI states, or the like that are indicated via a most recently received WUS.
[0075] The control signaling 210 may thereby clearly define UE behaviors for monitoring for a subsequent WUS 260 in the event of a WUS detection failure. The UE 115 may receive an indication that the WUS monitoring protocol is applicable for a quantity of DRX cycles, in some examples. For example, if the UE 115 does not receive a first WUS, the UE 115 may apply the indicated behavior for the quantity of DRX cycles before switching to a default behavior. The UE 115 may receive (e.g., via the control signaling 210 or some other message) an indication that the WUS monitoring protocol may be associated with a first set of cells. In some cases, one or more other WUS monitoring protocols may be associated with one or more other sets of cells. Thus, the UE 115 may have different WUS monitoring protocols to follow based on the set of cells the UE 115 is located within. Additionally, or alternatively, if the monitoring protocol is not included in the control signaling 210, or the UE 115 does not receive the control signaling 210, or both, then the monitoring protocol that the UE 115 follows may be a default monitoring protocol, defined as either the first monitoring protocol or the second monitoring protocol (e.g., based on one or more rules or configurations at the UE 115) . In some examples, the network entity 105 may also know the default monitoring protocol.
[0076] In the example illustrated in FIG. 2, the UE 115 may receive control signaling 210 that may indicate for the UE 115 to follow the first monitoring protocol if the UE 115 fails to receive a first WUS. The first monitoring protocol may be associated with a second set of monitoring parameters, which may include all candidate search space sets, TCI states, beams, or the like. That is, the first monitoring protocol may be associated with relatively aggressive monitoring by the UE 115. The UE 115 may receive the control signaling 210 indicating the first monitoring protocol from the network entity 105 upon connection with a network, or at some other time. The UE 115 may communicate one or more signals after receiving the control signaling 210 and before failing to receive a WUS.
[0077] In the example of FIG. 2, the UE 115 may monitor one or more monitoring occasions in a first set of WUS monitoring occasions 205-a, 205-b, and 205-d during a first DRX cycle 215 (e.g., an OFF duration of the DRX cycle 215) . The UE 115 may successfully receive a first WUS 260 in a third monitoring occasion 205-c of the first set of monitoring occasions. The first WUS 260 may include a first set of one or more monitoring parameters including a respective search space set, a respective TCI state, a respective beam, or the like. The UE 115 may transition to a wake state for an associated DRX ON duration 235 during the DRX cycle 215 based on the first WUS 260. The UE 115 may transmit or receive communications during the DRX ON duration 235 accordingly. The UE 115 may transition back to a sleep state at the start of the second DRX cycle 220 after the ON duration 235.
[0078] The UE 115 may monitor a second set of WUS monitoring occasions 205-a, 205-b, 205-c, and 205-d during the second DRX cycle 220. The UE 115 may monitor the second set of WUS monitoring occasions 205-a, 205-b, 205-c, and 205-d using the one or more first monitoring parameters indicated via the first WUS 260 received during the DRX cycle 215. For example, the UE 115 may only monitor a first search space set using a corresponding beam 230-a associated with the monitoring occasion 205-c based on the first set of parameters. However, the UE 115 may fail to receive or decode a WUS during the second DRX cycle 220. The UE 115 may thereby refrain from waking during the associated DRX ON duration 245. In some examples, the UE 115 may transmit a message to the network entity 105 that may indicate the absence of the WUS 260 detection in the second set of WUS monitoring occasions 205.
[0079] As described herein, because the control signaling 210 indicated the first WUS monitoring protocol and the UE 115 did not receive a WUS in the second DRX cycle 220, when the UE transitions to the third DRX cycle 225, the UE 115 may monitor each occasion of a third set of monitoring occasions 205-a, 205-b, and 205-d during the third DRX cycle 225 using a second set of WUS monitoring parameters associated with the first WUS monitoring protocol. The second set of monitoring parameters may include all beams 230 across all search space sets and TCI states. That is, the UE 115 may perform beam sweeping across the plurality of beams 230 supported by the UE 115 and multiple search space sets. The UE 115 may follow the first monitoring protocol to monitor for a WUS in the third DRX cycle 225, one or more other DRX cycles (not pictured in FIG. 2) until the UE 115 detects another WUS 260. In some examples, the UE 115 may refrain from entering a wake state during the associated DRX ON duration 250 if the UE 115 does not detect a WUS during the DRX cycle 225.
[0080] In some cases, the UE 115 may receive second control signaling (e.g., medium access control-control element (MAC-CE) or DCI, or some other type of control signaling) indicating a change from the indicated monitoring protocol to a different monitoring protocol for at least one DRX cycle of one or more subsequent DRX cycles. For example, the network entity 105 may indicate for the UE 115 to update from the first protocol to the second protocol, or vice versa. The network entity 105 may indicate for the UE 115 to update from the first protocol to the second protocol if the network entity 105 determines where the WUS 260 may be transmitted and that the most recently detected WUS 260 has already indicated corresponding parameters such that the UE 115 may correctly monitor without receiving explicit signaling from the network entity 105. The network entity 105 may also indicate for the UE 115 to update from the second protocol to the first protocol if the network entity 105 determines that the second protocol is failing. The updated protocol may improve reliability and throughput.
[0081] In some cases, the UE 115 may autonomously update its monitoring protocol based on certain criteria being met. The UE 115 may follow one or more transition protocols associated with various criteria being met to transition between the first and second monitoring protocols. In some examples, the UE 115 may update from the second monitoring protocol to the first monitoring protocol if a WUS 260 is not detected within a threshold quantity (e.g., N) of one or more contiguous DRX cycles. The threshold quantity may be a defined quantity (e.g., defined in a standard) or may be indicated to the UE 115 from the network entity 105 via some signaling (e.g., RRC, MAC-CE, DCI, or the like) . In some examples, the threshold quantity may be the same or different for different cells. That is, the UE 115 may be configured with a different threshold quantity for each cell or cell group that the UE 115 monitors.
[0082] In some examples, the UE 115 may switch from the second monitoring protocol to the first monitoring protocol if a WUS 260 is not detected within a threshold quantity (e.g., M) of one or more DRX cycles within a threshold time period (e.g., T) , which may correspond to a threshold quantity of slots, subframes, milliseconds, frames, or some other unit of time. The threshold quantity of DRX cycles, the time period, or both may be a defined quantity (e.g., defined in a standard) or may be indicated to the UE 115 from the network entity 105 via some signaling (e.g., RRC, MAC-CE, DCI, or the like) . In some examples, the threshold quantity of DRX cycles, the threshold time period, or both may be the same or different for different cells. That is, the UE 115 may be configured with the same or different thresholds for each cell or cell group that the UE 115 monitors.
[0083] In some examples, the UE 115 may switch from the first monitoring protocol to the second monitoring protocol if the UE 115 successfully decodes a WUS 260 using a same search space set identifier or TCI state identifier that was indicated via a most recently received WUS 260. If the UE 115 decodes one or more WUSs 260 using the indicated parameters for more than a threshold quantity (e.g., P) of contiguous DRX cycles, the UE 115 may determine to autonomously switch from the first monitoring protocol to the second monitoring protocol to reduce overhead.
[0084] In some examples, the UE 115 may switch from the first monitoring protocol to the second monitoring protocol if the UE 115 successfully decodes a WUS 260 using a same search space set identifier or TCI state identifier that was indicated via a most recently received WUS 260. If the UE 115 decodes one or more WUSs 260 using the indicated parameters for more than a threshold quantity (e.g., P) of DRX cycles within a threshold duration (e.g., T2) , the UE 115 may determine to autonomously switch from the first monitoring protocol to the second monitoring protocol to reduce overhead. The threshold duration may include a quantity of slots, subframes, milliseconds, frames, or some other unit of time. The threshold quantities and durations may be a defined quantity (e.g., defined in a standard) or may be indicated to the UE 115 from the network entity 105 via some signaling (e.g., RRC, MAC-CE, DCI, or the like) . In some examples, the threshold quantities and durations may be the same or different for different cells. That is, the UE 115 may be configured with a different threshold quantity or duration for each cell or cell group that the UE 115 monitors.
[0085] In accordance with various aspects discussed herein, the UE 115 may receive control signaling 210 from the network entity 105 that may indicate for the UE 115 to follow the first WUS monitoring protocol. According to the first monitoring protocol, if the UE 115 fails to detect a WUS 260 in a DRX cycle, the UE 115 may monitor all search space sets associated with subsequent sets of WUS monitoring occasions 205 in subsequent DRX cycles and may perform beam sweeping across multiple beams supported by the UE 115. The UE 115 may follow the first monitoring protocol to monitor for a WUS in some quantity of one or more subsequent DRX cycles until the UE 115 successfully detects a WUS 260. Examples of the second WUS monitoring protocol are described in further detail elsewhere herein, including with reference to FIG. 3.
[0086] FIG. 3 shows an example of a communication timeline 300 that supports WUS monitoring behaviors for a UE to follow in accordance with one or more aspects of the present disclosure. The communication timeline 300 may implement or be implemented by aspects of the communication timeline 200 described with reference to FIG. 2. For example, the communication timeline 300 may support signaling techniques for WUS transmissions and receptions between a UE 115 and a network entity 105, which may represent examples of a UE 115 and a network entity 105 as described with reference to FIG. 1, that include one or more parameters that indicate a WUS monitoring behavior (protocol) for the UE 115 to follow. By indicating a WUS protocol, the UE 115 and network entity 105 may promote more efficient coordination between devices and may improve latency.
[0087] In the example of FIG. 3, the UE 115 may receive control signaling 310 from the network entity 105 that may indicate for the UE 115 to follow a second monitoring protocol selected from a set of one or more candidate monitoring protocols supported by the UE 115 if the UE 115 fails to detect a WUS 360. The second monitoring protocol may indicate for the UE 115 to monitor for a WUS in one or more DRX cycles using a first set of one or more monitoring parameters that were indicated via a most recently received WUS. The UE 115 may receive the control signaling 310 indicating the second monitoring protocol from the network entity 105 upon connection with a network (e.g., via an RRC configuration) , or at some other time. The UE 115 may communicate one or more signals after receiving the control signaling 310 and before failing to receive a WUS.
[0088] In the example of FIG. 2, the UE 115 may monitor a first set of WUS monitoring occasions 305-a, 305-b, and 305-c during a first DRX cycle 315. The UE 115 may detect a first WUS 360 in the WUS monitoring occasion 305-c. The first WUS 360 may indicate for the UE 115 to wake up and perform communications during the associated DRX ON duration 335. The first WUS 360 may indicate a first set of one or more monitoring parameters 355 including a respective search space set, a respective TCI state, a respective beam 230 (e.g., the beam 230-a) , or any combination thereof. The UE 115 may detect the first WUS 360 by performing beam sweeping across a plurality of beams 330. Additionally, or alternatively, the UE 115 may monitor using the beam 330-a based on a previously received WUS or other indication.
[0089] The UE 115 may monitor a second set of WUS monitoring occasions 305-a, 305-b, and 305-c during the second DRX cycle 320. The UE 115 may monitor the second set of WUS monitoring occasions 305-a, 305-b, and 305-c using the one or more first monitoring parameters 355 indicated via the first WUS 360 received during the DRX cycle 315. For example, the UE 115 may only monitor a first search space set using a corresponding beam 330-a associated with the monitoring occasion 305-b based on the first set of monitoring parameters 355. In some cases, the second monitoring protocol may indicate for the UE 115 to monitor one or more subsequent WUS monitoring occasions 305 in one or more subsequent DRX cycles using the first set of monitoring parameters 355 indicated via the WUS 360 (e.g., a most recently received WUS 360) if the UE 115 fails to receive a WUS in a subsequent DRX cycle. The first set of one or more monitoring parameters 355 may indicate a subset of one or more beams, such as the beam 330-a, from among multiple beams supported by the UE 115, a subset of one or more search space sets, a subset of one or more TCI states, or any combination thereof. For example, if the UE 115 fails to receive the WUS in the second DRX cycle 320, the UE 115 may refrain from waking during the associated DRX ON duration 345. In some examples, the UE 115 may transmit a message to the network entity 105 that may indicate the absence of the WUS 360 detection in the second set of WUS monitoring occasions 305.
[0090] The UE 115 may monitor a third set of WUS monitoring occasions 305-a and 305-c during a third DRX cycle 325 in accordance with the first set of monitoring parameters 355 indicated via the first WUS 360 received via the first DRX cycle 315. The UE 115 may use the beam 330-a indicated in the monitoring parameters 355 of the first detected WUS 360 to monitor within a search space set indicated via the WUS 360 for another WUS. In some examples, the UE 115 may successfully detect, receive, and decode a second WUS 360 in the WUS monitoring occasion 305-c of the third DRX cycle 325 based on the first set of monitoring parameters 355. The second WUS 360 may indicate for the UE 115 to wake up for the associated DRX ON duration 350. In such cases, the UE 115 may use any parameters indicated via the second WUS 360 to monitor for subsequent WUSs in subsequent DRX cycles. Alternatively, if the UE 115 does not successfully receive a WUS in the third DRX cycle 325, the UE 115 may follow the second monitoring protocol to monitor subsequent sets of WUS monitoring occasions 305 during one or more subsequent DRX cycles (not pictured in FIG. 3) until the UE 115 successfully detects a second WUS 360.
[0091] The UE 115 may thereby monitor for a WUS according to a set of monitoring parameters 355 indicated via a most recently received WUS if the UE 115 fails to receive a WUS and if the control signaling 310 indicates the second monitoring protocol. By monitoring using the set of monitoring parameters 355 indicated via the most recently received WUS, the UE 115 may reduce processing and overhead as compared with monitoring across all beams and search space sets, as described with reference to the first monitoring protocol. However, the second monitoring protocol may be associated with reduced detection likelihood relative to the first monitoring protocol, in some examples. In some examples, the network entity 105 may plan to transmit one or more WUSs via a same search space set and using a same beam, and the network entity 105 may instruct the UE 115 to enter the second monitoring protocol so the network entity 105 does not have to continue to send parameters via the WUS.
[0092] In some examples, the network entity 105 may transmit signaling that dynamically instructs the UE 115 to switch between monitoring protocols, or the UE 115 may automatically switch between monitoring protocols based on one or more criteria, as described in further detail elsewhere herein, including with reference to FIG. 2.
[0093] In some examples, each WUS monitoring occasion 305 may be associated with a respective search space set. That is, each search space set may be associated with a single CORESET, and the CORESET may be associated with a single TCI state. As such, a WUS 360 may indicate a search space set for the UE 115 to monitor, and the search space set may indicate the CORESET and TCI state (e.g., beam 330) , as illustrated in FIGs. 2 and 3. In some examples, different TCI states may be associated with different physical downlink control channel (PDCCH) monitoring occasions (MOs) of a corresponding search space set for PDCCH repetition purposes. In such examples, the WUS 360 may be configured based on such a single search space set, while transmit beam-sweeping may be realized. As described herein, the parameters indicated via a WUS 360 may thereby include one or more search space set identifiers (e.g., for single search space set-to-TCI state scenarios) or may include one or more MO identifiers, one or more TCI state identifiers, one or more quasi co-location (QCL) sources associated with different MOs, or any combination thereof. If the control signaling indicates the first monitoring protocol and the UE 115 fails to detect a WUS 360, the UE 115 as described herein may thereby sweep across all search space sets and corresponding beams 330 in one or more subsequent DRX cycles. If the control signaling indicates the second monitoring protocol and the UE 115 fails to detect a WUS 360, the UE 115 as described herein may monitor a given set of one or more MOs using a given set of one or more TCI states and / or QCL sources that were indicated via a most recently received WUS 360.
[0094] FIG. 4 shows an example of a communication timeline 400 that supports WUS monitoring behaviors for a UE to follow in accordance with one or more aspects of the present disclosure. The communication timeline 400 may implement or be implemented by aspects of FIGs. 1–3. For example, the communication timeline 400 may support signaling techniques for WUS transmissions and receptions between a UE 115 and a network entity 105 that include one or more parameters that indicate a WUS monitoring behavior (protocol) for the UE 115 to follow. The UE 115 and the network entity 105 may represent examples of corresponding devices as described herein.
[0095] In some examples, the UE 115 may receive a WUS that indicates predicted search space set IDs, TCI states IDs, beams, or any combination thereof, for a group of multiple subsequent DRX cycles after the first DRX cycle in which the WUS is received. As described herein, if the UE 115 fails to receive a WUS that was intended to indicate monitoring parameters for multiple subsequent DRX cycles, and the control signaling received from the network entity 105 indicates that the UE 115 is to operate according to the first monitoring protocol if the UE 115 fails to receive a WUS, the UE 115 may monitor all subsequent search space sets across all of the DRX cycles using the second set of monitoring parameters associated with the first monitoring protocol (e.g., all beams, search space sets, etc. ) until the UE 115 successfully receives a WUS.
[0096] For example, as illustrated in FIG. 4, the UE 115 may receive, in a first DRX cycle 410, a first WUS 430 (e.g., via the SSB #1) that indicates a first set of monitoring parameters 435 for monitoring a subsequent set of monitoring occasions 405 in a subsequent DRX cycle 415. For example, the first WUS 430 may indicate a sequence of synchronization signal blocks (SSBs) and corresponding first monitoring parameters 435 (e.g., first beams, search space sets, etc. ) for the UE 115 to monitor in the monitoring occasions 405-a, 405-b, 405-c, and 405-d of the second DRX cycle 415. In the example of FIG. 3, the first monitoring parameters 435 may indicate a sequence of SSB #1, SSB #1, SSB #3, and SSB #3 for the monitoring occasions 405-a, 405-b, 405-c, and 405-d, respectively.
[0097] The UE 115 may monitor the monitoring occasions 405-a through 405-d of the second DRX cycle 415 according to the sequence of first monitoring parameters 435. However, the UE 115 in this example may fail to receive or decode a WUS in the second DRX cycle 415. The UE 115 may thereby follow the first monitoring protocol to monitor for a WUS in subsequent DRX cycles. In this example, the UE 115 may monitor all monitoring occasions 405 in subsequent DRX cycles, such as the third DRX cycle 420, using a second set of monitoring parameters 440 associated with the first monitoring protocol. The second set of monitoring parameters 440 may include all beams, SSBs, search space sets, and the like. That is, the UE 115 may aggressively monitor all search space sets in all monitoring occasions 405 of the third DRX cycle 420 based on the first monitoring protocol.
[0098] In the example of FIG. 4, the UE 115 may successfully receive and decode a WUS 430 in the monitoring occasion 405-c of the third DRX cycle 420. The WUS 430 may indicate third monitoring parameters 445 for the UE 115 to use to monitor for a WUS in the fourth DRX cycle 425. In some other examples, the UE 115 may not successfully decode any WUS in the third DRX cycle 420. In such examples, the UE 115 may continue to monitor for a WUS in remaining DRX cycles using the second monitoring parameters 440 (e.g., all beams and search spaces) until the UE 115 does successfully decode a WUS.
[0099] FIG. 5 shows an example of a communication timeline 500 that supports WUS monitoring behaviors for a UE to follow in accordance with one or more aspects of the present disclosure. The communication timeline 500 may implement or be implemented by aspects of FIGs. 1–4. For example, the communication timeline 500 may support signaling techniques for WUS transmissions and receptions between a UE 115 and a network entity 105 that include one or more parameters that indicate a WUS monitoring behavior (protocol) for the UE 115 to follow. The UE 115 and the network entity 105 may represent examples of corresponding devices as described herein.
[0100] In some examples, the UE 115 may receive a WUS that indicates predicted search space set IDs, TCI states IDs, beams, or any combination thereof, for a group of multiple subsequent DRX cycles after the first DRX cycle in which the WUS is received. As described herein, if the UE 115 fails to receive a WUS in a subsequent DRX cycle that was intended to indicate monitoring parameters for multiple subsequent DRX cycles, and the control signaling received from the network entity 105 indicates that the UE 115 is to operate according to the second monitoring protocol if the UE 115 fails to receive the WUS, then the UE 115 may monitor a single search space set in one or more subsequent DRX cycles based on a first set of monitoring parameters 535 indicated via a first WUS 530 (e.g., via the SSB #1) associated with a monitoring occasion 505-a until the UE 115 successfully receives a WUS.
[0101] For example, as illustrated in FIG. 5, the UE 115 may receive, in a first DRX cycle 510, the first WUS 530 (e.g., via the SSB #1) that indicates the first set of monitoring parameters 535 for monitoring a subsequent set of monitoring occasions 505 in a subsequent DRX cycle 515. For example, the first WUS 530 may indicate a sequence of synchronization signal blocks (SSBs) and corresponding first monitoring parameters 535 (e.g., first beams, search space sets, etc. ) for the UE 115 to monitor in the monitoring occasions 505-a, 505-b, 505-c, and 505-d of the second DRX cycle 515. The first monitoring parameters 535 may indicate a sequence of SSB #1, SSB #1, SSB #3, and SSB #3 for the monitoring occasions 505-a, 505-b, 505-c, and 505-d, respectively.
[0102] The UE 115 may monitor the monitoring occasions 505-a through 505-d of the second DRX cycle 515 according to the sequence of first monitoring parameters 535. However, the UE 115 in this example may fail to receive or decode a WUS in the second DRX cycle 515. The UE 115 may thereby follow the second monitoring protocol to monitor for a WUS in subsequent DRX cycles. In this example, the UE 115 may monitor one or more monitoring occasions 505 in subsequent DRX cycles, such as the third DRX cycle 520, using a single search space set based on the first set of monitoring parameters 535 indicated via the WUS 530 (e.g., a most recently received WUS 530) . For example, the UE 115 may use a final search space set (e.g., and corresponding beam) from among the sequence of search space sets indicated via the first set of monitoring parameters 535 to monitor across one or more DRX cycles until the UE 115 receives a WUS. As such, the UE 115 may perform power-saving monitoring on the one or more monitoring occasions 505 of the third DRX cycle 520 based on the second monitoring protocol. Additionally, or alternatively, the UE 115 may monitor according to the sequence of search space sets iteratively over multiple DRX cycles until the UE 115 receives a WUS.
[0103] In the example of FIG. 5, the UE 115 may successfully receive and decode a WUS 530 in the monitoring occasion 505-c of the third DRX cycle 520. The WUS 530 may indicate third monitoring parameters 540 for the UE 115 to use to monitor for a WUS in the fourth DRX cycle 525. In some other examples, the UE 115 may not successfully decode any WUS in the third DRX cycle 520. In such examples, the UE 115 may continue to monitor for a WUS in remaining DRX cycles using the first set of monitoring parameters 535 (e.g., a single search space set and a corresponding beam or a sequence of search space sets and corresponding beams) until the UE 115 does successfully decode a WUS.
[0104] FIG. 6 shows an example of a process flow 600 that supports WUS monitoring behaviors for a UE to follow in accordance with one or more aspects of the present disclosure. The process flow 600 illustrates aspects of signaling techniques that may be performed by a UE 115-a and a network entity 105-a, which may be examples of a UE 115 and a network entity 105 described with reference to FIGs. 1–5. Process flow 600 may support efficient signaling techniques for WUS transmissions and receptions between a UE 115-a and a network entity 105-a that include one or more parameters that indicate a WUS monitoring behavior (protocol) for the UE 115-a to follow.
[0105] In the following description of the process flow 600, the operations between the network entity 105-a and the UE 115-a may be performed in different orders or at different times than the example shown. Some operations may also be omitted from the process flow 600, and other operations may be added to the process flow 600.
[0106] At 605, the network entity 105-a may transmit, and the UE 115-a may receive, control signaling (e.g., RRC signaling) that may indicate a WUS monitoring protocol. The WUS monitoring protocol may be selected from at least a first WUS monitoring protocol and a second WUS monitoring protocol supported by the UE 115-a. In such cases, the WUS monitoring protocol may be associated with one or more WUS monitoring occasions allocated for the UE 115-a. The first WUS monitoring protocol and the second WUS monitoring protocol may represent examples of corresponding monitoring protocols, as described with reference to FIGs. 2–5.
[0107] At 610, the network entity 105-a may transmit, and the UE 115-a may receive, a first WUS associated with a first set of monitoring parameters (e.g., one or more of a TCI state, a search space set identifier, an SSB identifier, a beam identifier, a QCL source associated with one or more monitoring occasions, or any combination thereof) . The UE 115-a may receive the first WUS prior to a first DRX cycle of one or more DRX cycles of the UE 115-a, as described with reference to FIGs. 2–5. The first set of monitoring parameters may be associated with a first set of WUS monitoring occasions within at least the first DRX cycle.
[0108] In some examples, the UE 115-a may monitor the first WUS monitoring occasions within the first DRX cycle based on the first monitoring parameters indicated via the first WUS. In this example, however, the UE 115-a may fail to decode any WUS in the first DRX cycle.
[0109] At 615, the UE 115-a may monitor a second set of WUS monitoring occasions in at least a second DRX cycle that is after the first DRX cycle in time. The UE 115-a may monitor the second set of WUS monitoring occasions according to the first set of monitoring parameters indicated via the first WUS or a second set of monitoring parameters (e.g., one or more of a TCI state, a search space set identifier, an SSB identifier, a beam identifier, a QCL source associated with one or more monitoring occasions, or any combination thereof) based on which WUS monitoring protocol was indicated via the control signaling. In such cases, monitoring the second set of WUS monitoring occasions based on the WUS monitoring protocol indicated in the control signaling may be based on the absence of a WUS detection in the first set of WUS monitoring occasions.
[0110] If the control signaling indicates the second WUS monitoring protocol, the UE 115-a may monitor the second set of WUS monitoring occasions according to a subset of beams of a quantity of beams supported by the UE 115-a. The first set of monitoring parameters may indicate, via the first WUS, the subset of beams (e.g., along with one or more search space set identifiers, monitoring occasions, or both, as described with reference to FIGs. 2–5) . That is, if the control signaling indicates the second WUS monitoring protocol, the UE 115-a may monitor one or more subsequent DRX cycles using the monitoring parameters indicated via a most recently received WUS (e.g., the first WUS) for a threshold time period, until the UE 115-a successfully receives a WUS, until the network entity 105-a transmits signaling that indicates a switch in monitoring protocols, until the UE 115-a detects conditions that trigger an autonomous monitoring protocol switch, or any combination thereof.
[0111] If the control signaling indicates the first WUS monitoring protocol, the UE 115-a may monitor the second set of WUS monitoring occasions based on beam sweeping across the quantity of beams supported by the UE 115-a. That is, the UE 115-a may monitor the second set of WUS monitoring occasions using the second set of WUS monitoring parameters, which may include all beams supported by the UE 115-a (e.g., and corresponding search space sets, monitoring occasions, or both) . The first WUS monitoring protocol may thereby indicate for the UE 115-a to monitor all search spaces using all beams for some quantity of DRX cycles after the UE 115-a fails to detect a WUS. The UE 115-a may monitor all search space sets using beam sweeping for a threshold time period, until the UE 115-a successfully receives a WUS, until the network entity 105-a transmits signaling that indicates a switch in monitoring protocols, until the UE 115-a detects conditions that trigger an autonomous monitoring protocol switch, or any combination thereof.
[0112] The network entity 105-a may thereby transmit control signaling that indicates which WUS monitoring protocol the UE 115-a should use to monitor for a WUS if the UE 115-a fails to detect a WUS in a DRX cycle. The techniques described herein may thereby provide for improved efficiency, reduced overhead, and improved coordination between the network entity 105-a and the UE 115-a, among other examples.
[0113] FIG. 7 shows a block diagram 700 of a device 705 that supports control signaling for failed WUS detection operations in accordance with one or more aspects of the present disclosure. The device 705 may be an example of aspects of a UE 115 as described herein. The device 705 may include a receiver 710, a transmitter 715, and a communications manager 720. The device 705, or one or more components of the device 705 (e.g., the receiver 710, the transmitter 715, the communications manager 720) , may include at least one processor, which may be coupled with at least one memory, to, individually or collectively, support or enable the described techniques. Each of these components may be in communication with one another (e.g., via one or more buses) .
[0114] The receiver 710 may provide a means for receiving information such as packets, user data, control information, or any combination thereof associated with various information channels (e.g., control channels, data channels, information channels related to control signaling for failed WUS detection operations) . Information may be passed on to other components of the device 705. The receiver 710 may utilize a single antenna or a set of multiple antennas.
[0115] The transmitter 715 may provide a means for transmitting signals generated by other components of the device 705. For example, the transmitter 715 may transmit information such as packets, user data, control information, or any combination thereof associated with various information channels (e.g., control channels, data channels, information channels related to control signaling for failed WUS detection operations) . In some examples, the transmitter 715 may be co-located with a receiver 710 in a transceiver module. The transmitter 715 may utilize a single antenna or a set of multiple antennas.
[0116] The communications manager 720, the receiver 710, the transmitter 715, or various combinations or components thereof may be examples of means for performing various aspects of control signaling for failed WUS detection operations as described herein. For example, the communications manager 720, the receiver 710, the transmitter 715, or various combinations or components thereof may be capable of performing one or more of the functions described herein.
[0117] In some examples, the communications manager 720, the receiver 710, the transmitter 715, or various combinations or components thereof may be implemented in hardware (e.g., in communications management circuitry) . The hardware may include at least one of a processor, a digital signal processor (DSP) , a central processing unit (CPU) , an application-specific integrated circuit (ASIC) , a field-programmable gate array (FPGA) or other programmable logic device, a microcontroller, discrete gate or transistor logic, discrete hardware components, or any combination thereof configured as or otherwise supporting, individually or collectively, a means for performing the functions described in the present disclosure. In some examples, at least one processor and at least one memory coupled with the at least one processor may be configured to perform one or more of the functions described herein (e.g., by one or more processors, individually or collectively, executing instructions stored in the at least one memory) .
[0118] Additionally, or alternatively, the communications manager 720, the receiver 710, the transmitter 715, or various combinations or components thereof may be implemented in code (e.g., as communications management software or firmware) executed by at least one processor (e.g., referred to as a processor-executable code) . If implemented in code executed by at least one processor, the functions of the communications manager 720, the receiver 710, the transmitter 715, or various combinations or components thereof may be performed by a general-purpose processor, a DSP, a CPU, an ASIC, an FPGA, a microcontroller, or any combination of these or other programmable logic devices (e.g., configured as or otherwise supporting, individually or collectively, a means for performing the functions described in the present disclosure) .
[0119] In some examples, the communications manager 720 may be configured to perform various operations (e.g., receiving, obtaining, monitoring, outputting, transmitting) using or otherwise in cooperation with the receiver 710, the transmitter 715, or both.

A processor may also be implemented as a combination of computing devices (e.g., a combination of a DSP and a microprocessor, multiple microprocessors, one or more microprocessors in conjunction with a DSP core, or any other such configuration) . Any functions or operations described herein as being capable of being performed by a processor may be performed by multiple processors that, individually or collectively, are capable of performing the described functions or operations.
[0188] The functions described herein may be implemented using hardware, software executed by a processor, firmware, or any combination thereof. If implemented using software executed by a processor, the functions may be stored as or transmitted using one or more instructions or code of a computer-readable medium. Other examples and implementations are within the scope of the disclosure and appended claims. For example, due to the nature of software, functions described herein may be implemented using software executed by a processor, hardware, firmware, hardwiring, or combinations of any of these. Features implementing functions may also be physically located at various positions, including being distributed such that portions of functions are implemented at different physical locations.
[0189] Computer-readable media includes both non-transitory computer storage media and communication media including any medium that facilitates transfer of a computer program from one location to another. A non-transitory storage medium may be any available medium that may be accessed by a general-purpose or special-purpose computer. By way of example, and not limitation, non-transitory computer-readable media may include RAM, ROM, electrically erasable programmable ROM (EEPROM) , flash memory, compact disk (CD) ROM or other optical disk storage, magnetic disk storage or other magnetic storage devices, or any other non-transitory medium that may be used to carry or store desired program code means in the form of instructions or data structures and that may be accessed by a general-purpose or special-purpose computer or a general-purpose or special-purpose processor.

[0190] As used herein, including in the claims, “or” as used in a list of items (e.g., a list of items prefaced by a phrase such as “at least one of” or “one or more of” ) indicates an inclusive list such that, for example, a list of at least one of A, B, or C means A or B or C or AB or AC or BC or ABC (i.e., A and B and C) . Also, as used herein, the phrase “based on” shall not be construed as a reference to a closed set of conditions. For example, an example step that is described as “based on condition A” may be based on both a condition A and a condition B without departing from the scope of the present disclosure. In other words, as used herein, the phrase “based on” shall be construed in the same manner as the phrase “based at least in part on. ”
[0191] As used herein, including in the claims, the article “a” before a noun is open-ended and understood to refer to “at least one” of those nouns or “one or more” of those nouns. Thus, the terms “a, ” “at least one, ” “one or more, ” and “at least one of one or more” may be interchangeable. For example, if a claim recites “a component” that performs one or more functions, each of the individual functions may be performed by a single component or by any combination of multiple components. Thus, the term “a component” having characteristics or performing functions may refer to “at least one of one or more components” having a particular characteristic or performing a particular function. 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 more components. ” 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. ”
[0192] 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.
[0193] 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. If just the first reference label is used in the specification, the description is applicable to any one of the similar components having the same first reference label irrespective of the second reference label or other subsequent reference label.
[0194] The description set forth herein, in connection with the appended drawings, describes example configurations and does not represent all the examples that may be implemented or that are within the scope of the claims. The term “example” used herein means “serving as an example, instance, or illustration” and not “preferred” or “advantageous over other examples. ” The detailed description includes specific details for the purpose of providing an understanding of the described techniques. These techniques, however, may be practiced without these specific details. In some figures, known structures and devices are shown in block diagram form in order to avoid obscuring the concepts of the described examples.
[0195] The description herein is provided to enable a person having ordinary skill in the art to make or use the disclosure. Various modifications to the disclosure will be apparent to a person having ordinary skill in the art, and the generic principles defined herein may be applied to other variations without departing from the scope of the disclosure. Thus, the disclosure is not limited to the examples and designs described herein but is to be accorded the broadest scope consistent with the principles and novel features disclosed herein.
