Description
LOW-POWER SYNCHRONIZATION SIGNAL BEAMFORMING SUPPORT IN WIRELESS COMMUNICATIONS SYSTEMSTECHNICAL FIELD
[0001] The following relates generally to wireless communication, and more specifically to low-power synchronization signal (LP-SS) beamforming support in wireless communications systems.BACKGROUND
[0002] 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) . Such communication systems may support a low-power wakeup receiver (LP-WUR) architecture at a UE.SUMMARY
[0003] The described techniques relate to improved methods, systems, devices, and apparatuses that support low-power synchronization signal (LP-SS) beamforming in wireless communications systems. For example, the described techniques enable transmission of one or more beamformed synchronization signal (BF-SS) bursts to a user equipment (UE) that implements a low-power wakeup receiver (LP-WUR) architecture to support beam selection at the UE when the UE operates in a low-power mode. The described techniques may result in lower power consumption at the UE and may improve communication reliability between the UE and a wireless communications network.

The UE may include one or more memories storing processor executable code, and one or more processors coupled with (e.g., operatively, communicatively, functionally, electronically, or electrically) the one or more memories. The one or more processors may individually or collectively be operable to execute the code (e.g., directly, indirectly, after pre-processing, without pre-processing) to cause the UE to monitor, using a first radio of the UE, a first set of resources within a wakeup monitoring window for a WUS for the UE, where the wakeup monitoring window is configured for wakeup signaling monitoring for the UE using the first radio, receive, via a set of multiple beams and based on monitoring for the WUS, a set of multiple BF-SSs, where a respective BF-SS of the set of multiple BF-SSs corresponds to a respective beam of the set of multiple beams, monitor, using a second radio of the UE based on reception of the WUS during the wakeup monitoring window and on reception of the set of multiple BF-SSs, a paging occasion for a control signal for the UE, and communicate, using the second radio of the UE and via a beam of the set of multiple beams, one or more messages based on reception of the control signal within the paging occasion, where the control signal is associated with the one or more messages, and where the beam is based on one or more measurements associated with the set of multiple BF-SSs.

[0053] Various aspects of the present disclosure relate to a wireless communication device, such as a user equipment (UE) , that implements a low-power wakeup receiver (LP-WUR) architecture. The UE that implements the LP-WUR architecture may receive, from a network entity, such as a base station, one or more beamformed synchronization signal (BF-SS) bursts to support beam selection at the UE when the UE operates in a low-power mode. For instance, some wireless communication systems may support the use of a LP-WUR at a UE as hardware configured for low-power wakeup signal (LP-WUS) monitoring. As described herein, LP-WUS may be referred to as a wakeup signal (WUS) . As compared to a conventional wireless transceiver, also referred to as a main radio (MR) , the LP-WUR may implement a simpler hardware design, resulting in lower operational power. Accordingly, use of such LP-WURs may substantially reduce overall power consumption at the UE.
[0054] In idle and inactive modes, the UE may turn off the MR and switch to the LP-WUR to operate in a low-power mode in order to save power. In this low-power mode, when paging information is to be sent to the UE from a network entity, the UE may first receive an LP-WUS from the network entity. The LP-WUS may trigger the UE to wake up (e.g., to turn on the MR) to receive the paging information. In some cases, due to the LP-WUR’s low complexity, the LP-WUR may not support functions for receiving primary SSs (PSSs) and secondary SSs (SSSs) , which may be used by the UE to maintain time and frequency synchronization with the network entity.
[0055] Accordingly, wireless communication systems that support UEs implementing the LP-WUR architecture may, instead, transmit periodic LP-SSs to the UE, so that the LP-WUR of the UE may maintain time and frequency offsets within an acceptable range. In this way, LP-WUSs transmitted to the UE may be successfully received by the LP-WUR. Accordingly, the LP-WUR may periodically monitor the LP-SSs to maintain time and frequency synchronization with the network entity. When the UE detects an LP-WUS, the UE may turn on the MR to monitor for and in some cases receive paging information. For instance, the UE may use the MR to receive, during a next paging occasion, a control message (e.g., a paging physical downlink control channel (PDCCH) ) . The UE may additionally use the MR to receive any subsequent downlink messages (e.g., physical downlink shared channel (PDSCH) messages) scheduled by the control message and transmit uplink communications (e.g., physical uplink control channel (PUCCH) or physical uplink shared channel (PUSCH) messages) to the network entity before switching back to the LP-WUR.
[0056] While the UE operates in the low-power mode, the UE may move across different SS block (SSB) areas corresponding to different coverage areas of a cell. In some cases, a periodicity associated with such LP-SSs (such as a duration of time between transmission of each LP-SS) may be greater than a periodicity associated with the paging occasions. Accordingly, when the UE subsequently (e.g., after moving to a different SSB) detects an LP-WUS indicating that the UE should switch to the MR to receive the paging PDCCH, the UE may not have received synchronization information via a LP-SS since moving and, thus, may be unable to accurately track an optimal SSB beam to use to receive the paging PDCCH. As a result, the UE may decode paging PDCCHs in all SSB beams to ensure reliable reception of the paging information. However, some UE implementations may be unable to support such operations. Moreover, transmitting beamformed LP-SSs in all beam directions and in a same beam sweeping pattern based on the SSBs may not be practical as doing so may increase network signaling overhead and resource usage due to the always-on transmission of the LP-SSs and in some cases, the network entity may still transmit always-on SSBs as well.
[0057] In accordance with aspects of this disclosure, signaling techniques may enable a UE to track a beam (e.g., a beam having a signal quality or strength that satisfies a measurement threshold) when the UE switches from a LP-WUR to a MR for receiving a paging PDCCH, while also maintaining a low LP-SS overhead. To maintain the low LP-SS overhead, a LP-WUS monitoring window may be configured relative to transmission of one or multiple beamformed SS bursts between two periodic LP-SSs (e.g., between a first LP-SS and a second LP-SS) and before a paging occasion. Such techniques may enable the UE to utilize the beamformed SS bursts to select a beam (e.g., a beam having a signal quality or strength that satisfies a measurement threshold) prior to switching to the MR for receiving the paging information.
[0058] Aspects of the disclosure are further illustrated by and described with reference to various diagrams and flowcharts that relate to LP-SS beamforming support in wireless communications systems.
[0059] FIG. 1 shows an example of a wireless communications system 100 that supports LP-SS beamforming in wireless communications systems 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.
[0060] 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) .
[0061] 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.
[0062] 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.
[0063] 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.
[0064] 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) .
[0065] 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) ) .
[0066] 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., Radio Resource Control (RRC) , service data adaption 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.
[0067] 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.
[0068] 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) .
[0069] 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 multimedia / entertainment device (e.g., a radio, a MP3 player, or a video device) , a camera, a gaming device, a navigation / positioning device (e.g., GNSS (global navigation satellite system) devices based on, for example, GPS (global positioning system) , Beidou, GLONASS, or Galileo, or a terrestrial-based device) , a tablet computer, a laptop computer, a netbook, a smartbook, a personal computer, a smart device, a wearable device (e.g., a smart watch, smart clothing, smart glasses, virtual reality goggles, a smart wristband, smart jewelry (e.g., a smart ring, a smart bracelet) ) , a drone, a robot / robotic device, a vehicle, a vehicular device, a meter (e.g., parking meter, electric meter, gas meter, water meter) , a monitor, a gas pump, an appliance (e.g., kitchen appliance, washing machine, dryer) , a location tag, a medical / healthcare device, an implant, a sensor / actuator, a display, or any other suitable device configured to communicate via a wireless or wired medium. 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.
[0070] 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.
[0071] 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) .
[0072] 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.
[0073] 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) .
[0074] 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.
[0075] 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) ) .
[0076] 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) .
[0077] 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.
[0078] Some UEs 115 may be configured to employ operating modes that reduce power consumption, such as half-duplex communications (e.g., a mode that supports one-way communication via transmission or reception, but not transmission and reception concurrently) . In some examples, half-duplex communications may be performed at a reduced peak rate. Other power conservation techniques for the UEs 115 may include entering a power saving deep sleep mode when not engaging in active communications, operating using a limited bandwidth (e.g., according to narrowband communications) , operating using a LP-WUR, or a combination of these techniques. For example, some UEs 115 may be configured for operation using a narrowband protocol type that is associated with a defined portion or range (e.g., set of subcarriers or resource blocks (RBs) ) within a carrier, within a guard-band of a carrier, or outside of a carrier. Additionally, some UEs 115 may be configured for receiving a WUS using a LP-WUR.
[0079] 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.
[0080] 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.
[0081] 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.
[0082] 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.
[0083] 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.
[0084] 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.
[0085] 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) .
[0086] 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.
[0087] 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.
[0088] 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) .
[0089] 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) .
[0090] In accordance with aspects described herein, a UE 115 may be configured with a LP-WUR. The UE 115 may utilize the LP-WUR to receive one or more signals when the UE 115 operates in an inactive or low-power mode. For example, the UE 115 may utilize the LP-WUR to periodically receive a plurality of LP-SSs to maintain time and frequency synchronization with a network entity 105. The UE 115 may further utilize the LP-WUR to monitor for and receive a WUS, such as a LP-WUS (e.g., when the UE 115 may be instructed to wake up to receive a paging message from the network entity 105 in an upcoming paging occasion) . Prior to or after receiving the LP-WUS, the UE 115 may receive, from the network entity 105, a plurality of BF-SSs via a plurality of corresponding beams. The plurality of BF-SSs may enable the UE 115 to determine a beam (e.g., a beam having a signal quality or strength that satisfies a measurement threshold) to use to receive the paging message. The LP-WUS may cause the UE 115 to wake up by triggering the UE 115 to switch to a MR to receive the paging message in the upcoming paging occasion and via the determined beam. The paging message may schedule communication between the UE 115 and the network entity 105. Subsequently, the UE 115 may communicate with the network entity 105 via the determined beam and using the MR.
[0091] FIG. 2 shows an example of a signaling design 200 that supports LP-SS beamforming in wireless communications systems in accordance with one or more aspects of the present disclosure. In some examples, signaling design 200 may be implemented by aspects of the wireless communications system 100, as described with reference to FIG. 1. For example, a UE 115, a network entity 105, or a combination thereof, may be configured to operate in accordance with the signaling design 200. In some examples, the UE 115 may be configured with a LP-WUR, and the signaling design 200 may support the use of the LP-WUR at the UE 115 as the hardware for LP-WUS monitoring. The LP-WUR may implement a simpler hardware design than an MR operating at the UE 115, resulting in reduced power consumption at the UE 115.
[0092] In idle and inactive modes, the UE 115 may turn off the MR and switch to the LP-WUR to operate in a low-power mode in order to save power. In some cases, the LP-WUR may not support functions for receiving PSSs and SSSs, which may be used by the UE 115 to maintain time and frequency synchronization with the network entity 105 in order to reliably receive paging messages from the network entity 105. Accordingly, to support the low-power mode, the UE 115 may be configured to receive periodic LP-SSs 205. For example, the UE 115 may receive a first LP-SS 205-a, a second LP-SS 205-b, and a third LP-SS 205-c. The UE 115 may not be limited to receiving three LP-SSs 205 and may, instead, receive any number of LP-SSs 205. The LP-SSs 205 may be transmitted to the UE 115, from the network entity 105, in accordance with a periodicity configured by the network entity 105. The LP-WUR of the UE 115 may monitor the LP-SSs 205 to maintain time and frequency synchronization with the network entity 105. The LP-SSs 205 may enable the UE 115 to maintain time and frequency offsets within an acceptable range so that a LP-WUS 210 may be received.
[0093] When the UE 115 detects the LP-WUS 210, the UE 115 may switch from the LP-WUR to the MR of the UE 115 to receive a paging message. For instance, the UE 115 may use the MR to receive, during a next paging occasion 215, the paging message, such as via a control message (e.g., a PDCCH) . The UE 115 may additionally use the MR to receive one or more subsequent downlink messages (e.g., PDSCH messages) scheduled or indicated by the control message. The UE 115 may also transmit one or more uplink messages (e.g., PUCCH or PUSCH messages) to the network entity 105 using the MR before switching back to the LP-WUR.
[0094] In some cases, while the UE 115 operates in the low-power mode, the UE 115 may move across different SSB areas that may correspond to different areas of a serving cell. In some cases, a periodicity associated with the LP-SS 205 (such as a duration of time between each LP-SS 205) may be greater than a periodicity associated with the paging occasions 215. Accordingly, when the UE 115 detects the LP-WUS 210 (indicating an upcoming paging message) after moving to a different SSB, the UE 115 may not have received and measured a LP-SS 205, such as the second LP-SS 205-b, since moving. As a result, the UE 115 may be unable to accurately track a beam (e.g., such as a beam that satisfies a measurement threshold) to use to receive the paging message.
[0095] FIG. 3 shows an example of a signaling design 300 that supports LP-SS beamforming in wireless communications systems in accordance with one or more aspects of the present disclosure. In some examples, signaling design 300 may be implemented by aspects of the wireless communications system 100, as described with reference to FIG. 1. For example, UE 115, network entity 105, or a combination thereof, may be configured to operate in accordance with the signaling design 300. The signaling design 300 may support the use of the LP-WUR at the UE 115 for LP-WUS monitoring. Accordingly, the UE 115 may be configured to receive periodic LP-SSs 305, such as a first LP-SS 305-a, a second LP-SS 305-b, and a third LP-SS 305-c. The signaling design 300 may enable the UE 115 to track a beam (such as a beam that satisfies a measurement threshold) for the UE 115 to use to transmit and receive messages (e.g., receive a paging message) when the UE 115 switches from the LP-WUR to the MR. For instance, in accordance with aspects described herein, the UE 115 may be configured to receive one or more of a plurality of BF-SSs, such as one or more BF-SS bursts, to enable the UE 115 to more accurately track a beam. In some cases the one or more BF-SS bursts may be one or more beamformed SSB bursts 320. The UE 115 may be configured to receive one or more BF-SS bursts (a single beamformed SSB burst 320 is shown in FIG. 3) after a LP-WUS monitoring window 330 configured at the UE 115 and before a paging occasion 315. The LP-WUS monitoring window 330 may be a configurable period of time for the UE 115 to monitor for and receive one or more LP-WUSs 310 (a single LP-WUS 310 is shown in FIG. 3) . That is, in some cases, multiple transmissions or repetitions of the LP-WUS 310 may be received during the LP-WUS monitoring window 330. The LP-WUS monitoring window 330 may be configured relative to transmission (or reception) of the one or more BF-SS bursts, such as the one or more beamformed SSB bursts 320. For instance, the LP-WUS monitoring window 330 may be configured to occur a duration of time prior to transmission (or reception) of the one or more BF-SS bursts (e.g., the one or more beamformed SSB bursts 320) by the network entity 105. For instance, the UE 115 may be configured with an offset 325 that may indicate a duration of time between an end of the LP-WUS monitoring window 330 and transmission (or reception) of the one or more BF-SS bursts (e.g., the one or more beamformed SSB bursts 320) . In some cases, the offset 325 may indicate a duration of time between an end of the LP-WUS monitoring window 330 and a beginning of the paging occasion 315. In some cases, the offset 325 may indicate a duration of time between transmission (or reception) of the LP-WUS 310 itself and transmission (or reception) of the one or more BF-SS bursts (e.g., the one or more beamformed SSB bursts 320) (such as shown in FIG. 3) . In some cases the UE 115 may be configured with a plurality of such offsets 325. One or more of the offsets 325 may be determined based at least in part on a duration of time required for the UE 115 to switch from the LP-WUR to the MR. In some cases, the UE 115 may receive, via control signaling (e.g., RRC signaling, PDCCH, a Medium Access Control-Control Element (MAC-CE) , or other control signaling) from the network entity 105, configuration information indicating one or more offsets 325. In some cases, the configuration information may additionally, or alternatively, indicate a quantity of the one or more BF-SS bursts (e.g., the one or more beamformed SSB bursts 320) to be transmitted to the UE 115 between the LP-WUS monitoring window 330 and the paging occasion 315.
[0096] The LP-WUS monitoring window 330 may be configured and the one or more LP-WUSs 310 and the one or more BF-SS bursts (e.g., the one or more beamformed SSB bursts 320) may be received between two of the periodic LP-SSs 305. For example, the LP-WUS monitoring window 330 may be configured and the one or more LP-WUSs 310 and the one or more BF-SS bursts (e.g., the one or more beamformed SSB bursts 320) may be received between the second LP-SS 305-b and the third LP-SS 305-c. The configuration of the LP-WUS monitoring window 330 and reception of the one or more LP-WUSs 310 and the one or more BF-SS bursts (e.g., the one or more beamformed SSB bursts 320) are not limited to being between the second LP-SS 305-b and the third LP-SS 305-c and may, instead, be between any two LP-SSs 305.
[0097] In the example of FIG. 3, when the UE 115 is operating in an idle or low-power mode, the network entity 105 may transmit the LP-WUS 310 to the UE 115 to trigger the UE 115 to transition to an active mode to receive data or other information, such as a paging message, awaiting delivery to the UE 115. Accordingly, when the LP-WUS 310 is received at the UE 115, the UE 115 may begin a process of switching from the LP-WUR to the MR in order to receive the paging message in a next paging occasion 315. To support the UE 115 in tracking or selecting a beam (e.g., a beam having a signal quality or strength that satisfies measurement threshold) to use to receive the upcoming paging message, the network entity 105 may transmit the one or more beamformed SSB bursts 320 to the UE 115 after transmitting the LP-WUS 310. In some cases, the one or more beamformed SSB bursts 320 may be transmitted to (or received at) the UE 115 after an expiration of the offset 325. Receiving the one or more beamformed SSB bursts 320 after an expiration of the offset 325 may allow the UE 115 sufficient time to transition from operating the LP-WUR to operating the MR.
[0098] Each beamformed SSB burst of the one or more beamformed SSB bursts 320 may include a plurality of beamformed SSBs. Each beamformed SSB of the plurality of beamformed SSBs may in turn correspond to a different beam, such as a different SSB beam. Upon receiving the one or more beamformed SSB bursts 320, the UE 115 may measure one or more of the associated BF-SSs to determine whether the BF-SS (e.g., the beamformed SSB) satisfies a measurement threshold. Based on the determination, the UE 115 may select a beam corresponding with a BF-SS that satisfies the measurement threshold. In this way, the UE 115 may select a beam prior to receiving the paging message in the next paging occasion 315.
[0099] The UE 115 may, thereafter, monitor the paging occasion 315 using the MR and may receive the paging message via the selected beam. The UE 115 may subsequently communicate one or more messages to or from the network entity 105 using the MR and via the selected beam. After some period of time when the UE 115 again becomes idle or inactive, the UE 115 may transition from the MR back to the LP-WUR.
[0100] FIG. 4 shows an example of a low-power BF-SS configuration 400 that supports LP-SS beamforming in wireless communications systems in accordance with one or more aspects of the present disclosure. In some cases, the network entity 105 may transmit one or more BF-SS bursts to the UE 115 that consist of one or more beamformed low-power SS (LP-SS) bursts. That is, in the example of FIG. 4, rather than transmitting to the UE 115 BF-SS bursts that consist of the one or more beamformed SSB bursts 320 (as in the FIG. 3 example) , the network entity 105 may transmit BF-SS bursts that consist of beamformed LP-SS bursts. For instance, the network entity 105 may transmit one or more beamformed LP-SS bursts 420. The one or more beamformed LP-SS bursts 420 may be beamformed with a reduced granularity relative to the one or more beamformed SSB bursts 320 of FIG. 3. The one or more beamformed LP-SS bursts 420 may be aperiodic beamformed LP-SS bursts. Time and frequency resources associated with the one or more beamformed LP-SS bursts 420 may be dynamically indicated vid an LP-WUS or via control signaling such as RRC signaling.
[0101] Each beamformed LP-SS burst of the one or more beamformed LP-SS bursts 420 may consist of a plurality of beamformed LP-SSs, such as LP-SS 1, LP-SS 2, LP-SS 3, LP-SS 4. A beamformed LP-SS burst of the one or more beamformed LP-SS bursts 420 may not be limited to the four beamformed LP-SSs shown and may, instead, include fewer or additional beamformed LP-SSs. The plurality of beamformed LP-SSs of the one or more beamformed LP-SS bursts 420 may be transmitted via multiple LP-SS beams separated in a time domain. The beamformed LP-SSs of the one or more beamformed LP-SS bursts 420 may be transmitted from the network entity 105 in a beam sweeping pattern that follows a beam sweeping pattern of corresponding SSBs. Accordingly, each beamformed LP-SS in a beamformed LP-SS burst 420 may be associated with one or more SSBs, such as SSBs 430, and corresponding beams, such as SSB beams 440. The association between the beamformed LP-SS in the beamformed LP-SS burst 420 and the SSBs 430 may be configured by a quasi-co-location (QCL) relationship. For instance, for each beamformed LP-SS in the beamformed LP-SS burst 420 may be considered a QCL target, and for each QCL target, one or more of the SSBs 430 may be used as the QCL source. When multiple SSBs 430 are associated with a beamformed LP-SS in the beamformed LP-SS burst 420 the SSB beams corresponding to the multiple SSBs 430 may be spatially separated. This may ensure that when the UE 115 moves to an area served by a new SSB beam, there may be no ambiguity for the UE 115 to determine from the tracked LP-SS beam, which is the corresponding SSB beam. In some cases, the QCL relationships may be configured in a lookup table at the UE 115 (e.g., the lookup table may include a QCL indication of one or more SSB beams associated with each LP-SS beam) . In some cases, the lookup table including the QCL relationships may be configured by the network entity 105 and transmitted to the UE 115. The lookup table may be transmitted to the UE 115 in control signaling, such as RRC signaling, a PDCCH message, a MAC-CE, or other control signaling.
[0102] Accordingly, the UE 115 may receive one or more beamformed LP-SS bursts 420 transmitted from the network entity 105 to enable the UE 115 to identify a beam to use when transitioning from the LS-WUR to the MR to receive one or more messages. For instance, the UE 115 may receive one or more beamformed LP-SS bursts 420 and measure one or more of the associated beamformed LP-SSs to determine whether the beamformed LP-SS satisfies a measurement threshold. Based on the determining an LP-SS that satisfies the measurement threshold, the UE 115 may utilize the QCL relationship lookup table indicating the relationships between beamformed LP-SSs and SSBs, to determine one or more SSBs 430 and corresponding SSB beams 440 that are indicated as a source for the determined LP-SS. When multiple SSBs 430 are indicated as a source for the determined LP-SS, the UE 115 may select the SSB 430 that corresponds to a beam that is closest in proximity to a beam that the UE 115 most previously utilized.
[0103] By way of example, assume that prior to switching from the MR to the LP-WUR, the UE 115 was in SSB beam 5, which is in turn associated with beamformed LP-SS 1. At a later point in time, such as after the UE 115 has switched to the LP-WUR, the UE 115 may have moved to a different area of the cell. When the UE 115 subsequently receives the one or more beamformed LP-SS bursts 420 (such as after receiving a LP-WUS) , the UE 115 may detect that beamformed LP-SS 3 satisfies a measurement threshold. Based on this information, the UE 115 may utilize the QCL relationship lookup table to determine which SSB beam to use to receive one or more messages, such as a paging message, when the UE 115 switches back to the MR. For instance, the UE 115 may utilize the QCL relationship lookup table to determine that beamformed LP-SS 3 is associated with SSB 6 and SSB 8 and SSB beam 6 and SSB beam 8, respectively. To determine which of SSB beams 6 or 8 to use, the UE 115 may determine to use the beam that is the closest in proximity to the SSB beam 5, which was the beam that the UE 115 was in prior to switching to the LP-WUR. In this case, the UE 115 may select SSB beam 6, which is closer in proximity to SSB beam 5 than SSB beam 8 is.
[0104] FIG. 5 shows an example of a signaling design 500 that supports LP-SS beamforming in wireless communications systems in accordance with one or more aspects of the present disclosure. In some examples, signaling design 500 may be implemented by aspects of the wireless communications system 100, as described with reference to FIG. 1. For example, UE 115, network entity 105, or a combination thereof, may be configured to operate in accordance with the signaling design 500. The signaling design 500 may support the use of the LP-WUR at the UE 115 for LP-WUS monitoring. Accordingly, the UE 115 may be configured to receive periodic LP-SSs 505, such as a first LP-SS 505-a, a second LP-SS 505-b, and a third LP-SS 505-c. While operating the LP-WUR, the UE 115 may receive an LP-WUS 510 during an LP-WUS monitoring window 530. The LP-WUS 510 may be an indication for the UE 115 to wake up (e.g., to switch to the MR) to receive a paging message in a next paging occasion 515. The UE 115 may receive, from the network entity 105, one or more BF-SS burst to enable the UE 115 to determine a beam to use to receive the paging message.
[0105] The signaling design 500 may be similar to the signaling design 300 of FIG. 3, except that rather than receiving one or more beamformed SSB bursts 320 as the BF-SS bursts, the UE 115 may instead receive one or more beamformed LP-SS bursts 520 as the one or more BF-SS bursts. The one or more beamformed LP-SS bursts 520 may be an example of the one or more aperiodic beamformed LP-SS bursts, such as the one or more beamformed LP-SS bursts 420 described in referenced to FIG. 4. Unlike the one or more beamformed SSB bursts 320 (which the LP-WUR may be incapable of receiving) , the LP-WUR may be capable of receiving the one or more beamformed LP- SS bursts 520. As a result, the UE 115 may be configured to use the LP-WUR to receive the one or more beamformed LP-SS bursts 520 and then to switch to the MR after receipt of the one or more beamformed LP-SS bursts 520 in order to receive the paging message in the next paging occasion 515. In some cases, the UE 115 may be configured with an offset 525 that may indicate a duration of time between an end of the one or more beamformed LP-SS bursts 520 and a beginning of the paging occasion 515. The offset 525 may be determined based at least in part on a duration of time required for the UE 115 to switch from the LP-WUR to the MR. In some cases, the UE 115 may receive, via control signaling (e.g., RRC signaling, PDCCH, a MAC-CE, or other control signaling) from the network entity 105, configuration information indicating the offset 525. In some cases, the configuration information may additionally, or alternatively, indicate a quantity of the one or more beamformed LP-SS bursts 520 to be transmitted to the UE 115 between the LP-WUS monitoring window 530 and the paging occasion 515.
[0106] Accordingly, in the example of FIG. 5, the network entity 105 may transmit the one or more beamformed LP-SS bursts 520 to the UE 115 after transmitting the LP-WUS 510. Upon receiving the one or more beamformed LP-SS bursts 520, the UE 115 may measure one or more of the associated LP-SSs to determine whether the LP-SS satisfies a measurement threshold. Based on determining an LP-SS that satisfies the measurement threshold, the UE 115 may utilize the QCL relationship lookup table (such as described with reference to FIG. 4 and indicating the relationships between beamformed LP-SSs and SSBs) to determine a corresponding SSB beam to use to receive the paging message in the next paging occasion 515 (e.g., the lookup table may include a QCL indication of one or more SSB beams associated with each LP-SS beam) . After selecting the beam, the UE 115 may switch to the MR and use the selected beam to receive the paging message in the paging occasion 515. The paging occasion 515 may begin after an expiration of the offset 525, thereby allowing the UE 115 sufficient time to transition from operating the LP-WUR to operating the MR.
[0107] FIG. 6 shows an example of a signaling design 600 that supports LP-SS beamforming in wireless communications systems in accordance with one or more aspects of the present disclosure. In some examples, signaling design 600 may be implemented by aspects of the wireless communications system 100, as described with reference to FIG. 1. For example, UE 115, network entity 105, or a combination thereof, may be configured to operate in accordance with the signaling design 600. The signaling design 600 may support the use of the LP-WUR at the UE 115 for LP-WUS monitoring. Accordingly, the UE 115 may be configured to receive periodic LP-SSs 605, such as a first LP-SS 605-a, a second LP-SS 605-b, and a third LP-SS 605-c. While operating the LP-WUR, the UE 115 may receive an LP-WUS 610 during an LP-WUS monitoring window 630. The LP-WUS 610 may be an indication for the UE 115 to wake up (e.g., to switch to the MR) to receive a paging message in a next paging occasion 615. The UE 115 may additionally receive, from the network entity 105, one or more BF-SS burst to enable the UE 115 to determine a beam to use to receive the paging message.
[0108] The signaling design 600 may be similar to the signaling design 500 of FIG. 5, except that rather than receiving one or more beamformed LP-SS bursts 520 after receiving the LP-WUS 510, one or more beamformed LP-SS bursts 620 may be received prior to receiving LP-WUS 610. The one or more beamformed LP-SS bursts 620 may be an example of the one or more aperiodic beamformed LP-SS bursts, such as the one or more beamformed LP-SS bursts 420 described in referenced to FIG. 4. Accordingly, in the example of FIG. 6, the network entity 105 may transmit the one or more beamformed LP-SS bursts 620 to the UE 115 before transmitting the LP-WUS 610. Upon receiving the one or more beamformed LP-SS bursts 620, the UE 115 may measure one or more of the associated LP-SSs to determine whether the LP-SS satisfies a measurement threshold. Based on determining an LP-SS that satisfies the measurement threshold, the UE 115 may utilize the QCL relationship lookup table (such as described with reference to FIG. 4 and indicating the relationships between beamformed LP-SSs and SSBs) to determine a corresponding SSB beam to use to receive the paging message in the next paging occasion 615 (e.g., the lookup table may include a QCL indication of one or more SSB beams associated with each LP-SS beam) . After selecting the beam, the UE 115 may receive the LP-WUS 610 and may be triggered to switch to the MR in order to receive the paging message in the next paging occasion 615. The UE 115 may use the selected beam to receive the paging message in the next paging occasion 615. In some cases, the paging occasion 615 may begin after an expiration of an offset 625, which may be a duration of time between transmission (or reception) of the LP-WUS 610 and a beginning of the paging occasion 615. The offset 625 may be determined based at least in part on a duration of time required for the UE 115 to switch from the LP-WUR to the MR.
[0109] In some cases, the UE 115 may receive, via control signaling (e.g., RRC signaling, PDCCH, MAC-CE, or other control signaling) from the network entity 105, configuration information indicating the offset 625. In some cases, the configuration information may additionally, or alternatively, indicate a quantity of the one or more beamformed LP-SS bursts 620 to be transmitted to the UE 115 between a periodic LP-SS 605 and a LP-WUS 610.
[0110] FIG. 7 shows an example of a process flow 700 that supports LP-SS beamforming in wireless communications systems in accordance with one or more aspects of the present disclosure. In some examples, the process flow 700 may implement or be implemented by aspects of the wireless communications system 100, as described with reference to FIG. 1. For example, the process flow 700 may illustrate the flow of signals between UE 115-a and network entity 105-a, which may be examples of UE 115 and network entity 105, respectively, as described with reference to FIGs. 1 to 6.
[0111] In the following description of the process flow 700, the operations between the UE 115-a and the network entity 105-a may be performed in a different order or at different times than the example order and times shown. Some operations may also be omitted and other operations may be added.
[0112] At 705, when operating in an idle or low-power mode, the UE 115-a may use a first radio of the UE 115-a, such as an LP-WUR, to monitor, during a configured LP-WUS monitoring window, a first set of resources for an LP-WUS. The LP-WUS may be an indication for the UE 115-a to wake up to receive a paging message to be delivered to the UE 115-a during an upcoming paging occasion.
[0113] At 710, the network entity 105 may transmit and the UE 115-a may receive, using the first radio, the LP-WUS. The LP-WUS may be received during the LP-WUS monitoring window.
[0114] At 715, the LP-WUS may trigger the UE 115-a to switch from the first radio to a second radio, such as a MR.
[0115] At 720, the network entity 105-a may transmit and the UE 115-a may receive, using the second radio, one or more BF-SS bursts, such as one or more beamformed SSB bursts. The one or more BF-SS bursts may enable the UE 115-a to identify a beam to receive the paging message (e.g., a beam having a signal quality or strength that satisfies a measurement threshold) . In some cases, the BF-SS bursts may be transmitted (or received) after expiration of an offset. Where the offset may indicate a duration of time between an end of the LP-WUS monitoring window (or transmission or receipt of the LP-WUS) and transmission (or receipt) of the BF-SS bursts.
[0116] At 725, the UE 115-a may measure one or more of the BF-SSs of the one or more BF-SS bursts to determine a BF-SS (e.g., a beamformed SSB) that satisfies a measurement threshold, and a corresponding beam, such as a SSB beam.
[0117] At 730, the UE 115-a may monitor, using the second radio, a next paging occasion for the paging message.
[0118] At 735, the network entity 105-a may transmit and the UE 115-a may receive, using the second radio and via the beam determined at 725, the paging message during the paging occasion.
[0119] At 740, the UE 115-a may communicate with the network entity 105-a (such as by sending or receiving one or more messages) using the second radio and via the beam determined at 725.
[0120] FIG. 8 shows an example of a process flow 800 that supports LP-SS beamforming in wireless communications systems in accordance with one or more aspects of the present disclosure. In some examples, the process flow 800 may implement or be implemented by aspects of the wireless communications system 100, as described with reference to FIG. 1. For example, the process flow 800 may illustrate the flow of signals between the UE 115-b and the network entity 105-b.
[0121] In the following description of the process flow 800, the operations between the UE 115-b and the network entity 105-b may be performed in a different order or at different times than the example order and times shown. Some operations may also be omitted and other operations may be added.
[0122] At 805, when operating in an idle or low-power mode, the UE 115-b may use a first radio of the UE 115-b, such as an LP-WUR, to monitor, during a configured LP-WUS monitoring window, a first set of resources for an LP-WUS.

The one or more BF-SS bursts may enable the UE 115-b to identify a beam to receive the paging message (e.g., a beam having a signal quality or strength that satisfies a measurement threshold) .
[0125] At 820, the UE 115-b may measure one or more of the BF-SSs (e.g., one or more beamformed LP-SS) of the one or more BF-SS bursts to determine a BF-SS (e.g., a beamformed LP-SS) that satisfies a measurement threshold.

[0126] At 825, the UE 115-b may switch from the first radio to a second radio, such as a MR.
[0127] At 830, the UE 115-b may monitor, using the second radio, a next paging occasion for the paging message. In some cases, the paging occasion may begin after an expiration of an offset.

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. ”
[0287] The term “determine” or “determining” or “identify” or “identifying” encompasses a variety of actions and, therefore, “determining” or “identifying” 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” or “identifying” can include receiving (such as receiving information or signaling, e.g., receiving information or signaling for determining, receiving information or signaling for identifying) , accessing (such as accessing data in a memory, or accessing information) and the like. Also, “determining” or “identifying” can include resolving, obtaining, selecting, choosing, establishing and other such similar actions.
