[0002] This patent application claims the benefit of U.S. Patent Application No. 18 / 297,588, filed April 7, 2023, entitled “GROUP BASED BEAMREPORT ENHANCEMENT FOR MOBILITY”, which is assigned to the assignee of this application and is expressly incorporated herein by reference. Technical Field

[0003] The following pertains to wireless communications, including group-based beam reporting enhancements for mobility. Background Technology

[0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, and broadcasting. These systems can support communication with multiple users by sharing 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-A 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 Extended Orthogonal Frequency Division Multiplexing (DFT-S-OFDM). A wireless multiple access communication system may include one or more base stations, each supporting wireless communication for communication devices, which may be referred to as User Equipment (UE). Summary of the Invention

[0005] The described techniques relate to improved methods, systems, devices, and apparatuses that support group-based beam report enhancements for layer 1 (Ll) / layer 2 (L2) triggered mobility (LTM). For example, a user equipment (UE) can perform a group-based report in which the UE measures multiple channel measurement resource (CMR) sets corresponding to a candidate cell and reports measurements associated with the multiple CMR sets. In some examples, the UE can transmit a group-based measurement report that indicates measurements of reference signals from the candidate cell received by the UE via the CMR sets, which in some cases can be concurrently or simultaneously received at the UE. For example, the UE can monitor the CMR sets for reference signals from the candidate cell and measure signal strengths associated with one or more reference signal pairs, where each reference signal pair includes a respective first reference signal from a first CMR set and a respective second reference signal from a second CMR set. That is, each reference signal in the reference signal pair can correspond to a different CMR set of the candidate cell. Additionally or alternatively, the UE can perform a group-based report for one or more additional CMR sets corresponding to a second cell (e.g., a serving cell or a different candidate cell). Additionally or alternatively, the first CMR set can correspond to the candidate cell, while the second CMR set can correspond to the second cell.

[0054] A user equipment (UE) can support communication with multiple transmission and reception points (TRPs). For example, the UE can simultaneously receive signaling from multiple TRPs. To support multi-TRP (mTRP), the UE can transmit one or more channel state information (CSI) reports (e.g., group-based measurement reports) to one or more of the multiple TRPs. A CSI report can include information indicating one or more measured signal strengths (e.g., reference signal received power (RSRP) as measured by the UE) and information indicating one or more channel measurement resources (CMRs) (e.g., reference signals) to which the measured signal strengths correspond. In some aspects, for example, a first TRP can transmit reference signals via a first set of CMRs while switching between different transmission beams, and a second TRP can transmit reference signals via a second set of CMRs while switching between different transmission beams. Thus, the UE can use a group-based beam report to indicate which reference signals have relatively greatest signal strengths. A group-based beam report can refer to a report that includes multiple measurements of multiple cells, and in some cases can include multiple beam measurements (e.g., measurements of beams of a cell by the UE) of multiple cells.

[0055] To reduce latency during cell handover, layer 1 (L1) / layer 2 (L2) triggered mobility (LTM) can be utilized. For example, a serving cell (e.g., supported by a network entity) can use L1 (e.g., downlink control information (DCI)) or L2 (e.g., medium access control (MAC) control element (MAC-CE)) signaling to trigger a cell handover for a UE from the serving cell to a candidate cell, which can be a cell that the UE is not communicating or connected with. The candidate cell can be a dormant serving cell or a non-serving cell. In some cases, the UE can be configured to measure and report reference signals from the candidate cell. For example, L1 candidate cell reporting can include measurements from one or more serving cells, candidate cells, or both. However, group-based reporting can only support serving cells.

[0056] According to aspects herein, a candidate cell can be associated with one or more sets of CMRs, and each set of CMRs can correspond to a different TRP. That is, a first TRP can use resources within a first CMR to transmit reference signals, and a second TRP can use resources within a second set of CMRs to transmit reference signals. A UE can perform group-based reporting based on the set of CMRs corresponding to the candidate cell.

[0057] In some examples, the UE can transmit a group-based measurement report indicating measurements of reference signals from the candidate cell. For example, the UE can measure signal strengths associated with one or more pairs of reference signals, where each pair of reference signals includes a respective first reference signal from the first set of CMRs and a respective second reference signal from the second set of CMRs. That is, each reference signal in the pair of reference signals can correspond to a different set of CMRs from the candidate cell. Additionally or alternatively, the UE can perform group-based reporting for one or more additional sets of CMRs corresponding to a second cell (e.g., a serving cell or a different candidate cell). Additionally or alternatively, the first set of CMRs can correspond to the candidate cell, while the second set of CMRs can correspond to the second cell.

[0058] Aspects of the disclosure are first described in the context of a wireless communications system. Additional aspects of the disclosure are described in the context of process flows. Aspects of the disclosure are further illustrated by and described in connection with apparatus diagrams, system diagrams, and flowcharts related to group-based beam reporting enhancements for LTM.

[0059] Figure 1 An example of a wireless communications system 100 that supports group-based beam reporting enhancements for LTM is shown in accordance with one or more aspects of the present disclosure. The wireless communications system 100 can include one or more network entities 105, one or more UEs 115, and a core network 130. In some examples, the wireless communications system 100 can 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 according to some other wireless standard, including future 5G standards and wireless technologies not expressly mentioned herein.

[0060] The network entities 105 can be dispersed throughout the geographic area of the wireless communications system 100, and can each include devices in different forms or having different capabilities. In various examples, the network entities 105 can be referred to as network elements, mobility elements, radio access network (RAN) nodes, or network equipment, among other nomenclature. In some examples, the network entities 105 and the UEs 115 can wirelessly communicate with one another via one or more communication links 125 (e.g., radio frequency (RF) access links). For example, a network entity 105 can support a coverage area 110 (e.g., a geographic coverage area) within which UEs 115 and network entities 105 can establish one or more communication links 125. The coverage area 110 can be an example of a geographic area over which network entities 105 and UEs 115 can support signal communication in accordance with one or more radio access technologies (RATs).

[0061] The UEs 115 can be dispersed throughout the coverage areas 110 of the wireless communications system 100, and each UE 115 can be stationary or mobile, or both at different times. The UEs 115 can be devices in different forms or having different capabilities. Figure 1 Some example UEs 115 are illustrated. The UEs 115 described herein can be able to communicate with various types of base stations, network entities, or wireless devices, including macro gNBs, network entities, or small cell gNBs, as well as other UEs 115, as described herein. Figure 1 The UEs 115 described herein can be able to communicate with various types of base stations, network entities, or wireless devices, including macro gNBs, network entities, or small cell gNBs, as well as other UEs 115, as described herein.

[0062] As described herein, a node of the wireless communications system 100, which can be referred to as a network node or a wireless node, can be a network entity 105 (e.g., any of the network entities described herein), a UE 115 (e.g., any of the UEs described herein), a network controller, a device, a apparatus, 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 can be a UE 115. As another example, a node can be a network entity 105. As yet another example, a first node can be configured to communicate with a second node or a third node. In one aspect of this example, the first node can be a UE 115, the second node can be a network entity 105, and the third node can be a UE 115. In another aspect of this example, the first node can be a UE 115, the second node can be a network entity 105, and the third node can be a network entity 105. In other aspects of this example, the first node, the second node, and the third node can be different with respect to these examples. Similarly, references to a UE 115, a network entity 105, a device, an apparatus, a computing system, etc., can include the disclosure of the UE 115, the network entity 105, the device, the apparatus, the computing system, etc., as a node. For example, a 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, the network entities 105 can communicate with the core network 130 or with each other or both. For example, the network entities 105 can communicate with the core network 130 via one or more backhaul communication links 120 (e.g., according to an SI, N2, N3, or other interface protocol). In some examples, the network entities 105 can communicate with each other via backhaul communication links 120 (e.g., according to an X2, Xn, or other interface protocol) either directly (e.g., direct point-to-point between network entities 105) or indirectly (e.g., via core network 130). In some examples, the network entities 105 can communicate with each other via midhaul communication links 162 (e.g., according to a midhaul interface protocol) or front-haul communication links 168 (e.g., according to a front-haul interface protocol), or any combination thereof. The backhaul communication links 120, midhaul communication links 162, or front-haul communication links 168 can be or include one or more wired links (e.g., electrical, fiber optic), one or more wireless links (e.g., radio, wireless optical), etc., or various combinations thereof. The UEs 115 can communicate with the core network 130 via communication links 155.

[0064] One or more of the network entities 105 described herein can include or can be referred to as a base station 140 (e.g., a transceiver base station, a radio base station, an NR base station, an access point, a radio transceiver, a NodeB, an evolved NodeB (eNB), a Next Generation NodeB or Guy NodeB (any of which can 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, the network entities 105 (e.g., base stations 140) can be implemented in an aggregated (e.g., monolithic, self-standing) base station architecture that can be configured to utilize protocol stacks that are physically or logically integrated within a single network entity 105 (e.g., a single RAN node such as a base station 140).

[0065] In some examples, the network entity 105 can be implemented in a disaggregated architecture (e.g., a disaggregated base station architecture, a disaggregated RAN architecture) that can be configured to utilize a protocol stack distributed physically or logically among two or more network entities 105, such as an integrated access 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, the network entity 105 can include one or more of a central unit (CU) 160, a distributed unit (DU) 165, a radio unit (RU) 170, a RAN intelligent controller (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) 180 system, or any combination thereof. The RU 170 can also be referred to as a radio head, an intelligent radio head, a remote radio head (RRH), a remote radio unit (RRU), or a TRP. One or more components of the network entity 105 in a disaggregated RAN architecture can be co-located, or one or more components of the network entity 105 can be in distributed locations (e.g., separate physical locations). In some examples, one or more network entities 105 of a disaggregated RAN architecture can be implemented as virtual units (e.g., a virtual CU (VCU), a virtual DU (VDU), a virtual RU (VRU)).

[0066] The functional split between the CU 160, the DU 165, and the RU 170 is flexible and can support different functions depending on which functions (e.g., network layer functions, protocol layer functions, baseband functions, RF functions, and any combination thereof) are performed at the CU 160, the DU 165, or the RU 170. For example, a functional split of a protocol stack can be employed between the CU 160 and the DU 165, such that the CU 160 can support one or more layers of the protocol stack, and the DU 165 can support one or more different layers of the protocol stack. In some examples, the CU 160 can host higher protocol layer (e.g., Layer 3 (L3), Layer 2 (L2)) functionality and signaling (e.g., Radio Resource Control (RRC), Service Data Adaptation Protocol (SDAP), Packet Data Convergence Protocol (PDCP)). The CU 160 can connect to one or more DUs 165 or RUs 170, and the one or more DUs 165 or RUs 170 can host lower protocol layers, such as Layer 1 (LI) (e.g., Physical (PHY) layer) or L2 (e.g., Radio Link Control (RLC) layer, Medium Access Control (MAC) layer) functionality and signaling, and can each be at least partially controlled by the CU 160. Additionally or alternatively, a functional split of a protocol stack can be employed between the DU 165 and the RU 170, such that the DU 165 can support one or more layers of the protocol stack, and the RU 170 can support one or more different layers of the protocol stack. The DU 165 can support one or more different cells (e.g., via one or more RUs 170). In some cases, the functional split between the CU 160 and the DU 165 or between the DU 165 and the RU 170 can be within a protocol layer (e.g., some functions of a protocol layer can be performed by one of the CU 160, the DU 165, or the RU 170, while other functions of that protocol layer are performed by a different one of the CU 160, the DU 165, or the RU 170). The CU 160 can be further split in functionality into CU control plane (CU-CP) and CU user plane (CU-UP) functions. The CU 160 can connect to one or more DUs 165 via a backhaul communication link 162 (e.g., Fl, Fl-c, Fl-u), and the DU 165 can connect to one or more RUs 170 via a front-haul communication link 168 (e.g., open front-haul (FH) interface). In some examples, the backhaul communication link 162 or the front-haul communication link 168 can be implemented according to an interface (e.g., channel) between layers of a protocol stack that are supported by the respective network entities 105 that communicate via these communication links.

[0067] In some wireless communications systems (e.g., wireless communications system 100), infrastructure and spectrum resources for radio access can support wireless backhaul link capabilities to supplement wired backhaul connections to provide an IAB network architecture (e.g., to core network 130). In some cases, in an IAB network, one or more network entities 105 (e.g., IAB nodes 104) can be partially controlled by one another. One or more IAB nodes 104 can be referred to as a donor entity or IAB donor. One or more DUs 165 or one or more RUs 170 can be partially controlled by one or more CUs 160 associated with a donor network entity 105 (e.g., a donor base station 140). One or more donor network entities 105 (e.g., IAB donors) can communicate with one or more additional network entities 105 (e.g., IAB nodes 104) via supported access and backhaul links (e.g., backhaul communication links 120). An IAB node 104 can include an IAB mobile terminal (IAB-MT) controlled (e.g., scheduled) by a coupled DU 165 of an IAB donor. An IAB-MT can include a separate set of antennas for relaying communications with UEs 115 or can share the same antennas (e.g., of an RU 170) of the IAB node 104 for accessing via the DU 165 of the IAB node 104 (e.g., referred to as a virtual IAB-MT (vIAB-MT)). In some examples, an IAB node 104 can include a DU 165 that supports a communication link with an additional entity (e.g., IAB node 104, UE 115) within a relay chain or configuration (e.g., downstream) of an access network. In such cases, one or more components of the disaggregated RAN architecture (e.g., one or more IAB nodes 104 or components of an IAB node 104) can be configured to operate according to the techniques described herein.

[0068] In cases where the techniques described herein are applied in the context of a disaggregated RAN architecture, one or more components of the disaggregated RAN architecture can be configured to support group-based beam reporting enhancements for LTMs as described herein. For example, some operations described as being performed by a UE 115 or a network entity 105 (e.g., base station 140) can additionally or alternatively be performed by one or more components of the disaggregated RAN architecture (e.g., IAB node 104, DU 165, CU 160, RU 170, RIC 175, SMO 180).

[0069] A UE 115 can include or can 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” can also be referred to as a unit, a station, a terminal, or a client, among other examples. A UE 115 can also include or can 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 can include or can 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 can be implemented in various objects such as appliances or vehicles, among other examples.

[0070] The UEs 115 described herein can be able to communicate with various types of devices, such as other UEs 115 that can sometimes act as relays or Figure 1 as shown.

[0071] The UEs 115 and the network entities 105 can wirelessly communicate with each other using resources associated with one or more carriers via one or more communication links 125 (e.g., access links). The term “carrier” can refer to a set of RF spectrum resources having a defined physical layer structure for supporting communication links 125. For example, a carrier used for a communication link 125 can include a portion of an RF spectrum band (e.g., a bandwidth part (BWP)) operating according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel can carry acquisition signaling (e.g., synchronization signals, system information), control signaling (e.g., control channels), user data (e.g., data channels), or other signaling. The wireless communications system 100 can support communication with a UE 115 using carrier aggregation or multi-carrier operation. According to a carrier aggregation configuration, a UE 115 can be configured with multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation can be used for both Frequency Division Duplex (FDD) and Time Division Duplex (TDD) component carriers. Communications between a network entity 105 and other devices can refer to communications between these devices and any portion of the network entity 105 (e.g., an entity, a sub-entity). For example, the terms “transmit,” “receive,” or “communicate” can refer to any portion of the network entity 105 (e.g., a base station 140, a CU 160, a DU 165, a RU 170) communicating with another device (e.g., directly or via one or more other network entities 105).

[0072] The signal waveform transmitted via a carrier may include multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques, such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform extended OFDM (DFT-S-OFDM)). In a system employing MCM, a resource element may refer to a resource of one symbol period (e.g., the duration of one modulation symbol) and one subcarrier, in which case the symbol period and subcarrier spacing may be inversely related. The number of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the decoding rate of the modulation scheme, or both), such that a relatively high number of resource elements (e.g., in the transmission duration) and a relatively high-order modulation scheme can correspond to a relatively high communication rate. Wireless communication resources may refer to a combination of RF spectrum resources, temporal resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial resources can increase the data rate or data integrity used for communication with UE 115.

[0073] The time interval for network entity 105 or UE 115 can be expressed as a multiple of a basic time unit, such as the sampling period T. s =1 / (Δf) max ·N f ) seconds, where Δf max This can represent the supported subcarrier spacing, while N f The supported Discrete Fourier Transform (DFT) size can be represented. The time interval of the communication resources can be organized according to radio frames, each with a specified duration (e.g., 10 milliseconds (ms)). Each radio frame can 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 time slots, and each subframe or time slot may have the same duration. In some examples, a frame may (e.g., in the time domain) be divided into subframes, and each subframe may be further divided into a number of time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the subcarrier spacing. Each time slot may include a number of symbol periods (e.g., depending on the length of the cyclic prefix appended to each symbol period). In some wireless communication systems 100, time slots may be further divided into multiple micro-time slots associated with one or more symbols. Excluding the cyclic prefix, each symbol period may be associated with one or more (e.g., N) symbols. f The duration of a symbol period is associated with a ( ) sampling period. The duration of a symbol period can depend on the subcarrier spacing or the operating frequency band.

[0075] A subframe, a slot, a mini-slot, or a symbol can be the smallest scheduling unit (e.g., in the time domain) of the wireless communications system 100 and can be referred to as a transmission time interval (TTI). In some examples, the TTI duration (e.g., the number of symbol periods in a TTI) can be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communications system 100 (e.g., in the time domain) can be dynamically selected (e.g., in bursts of shortened TTIs (sTTIs)).

[0076] Physical channels can be multiplexed according to various techniques to communicate using a carrier. For example, physical control channels and physical data channels can be multiplexed for signaling via a downlink carrier 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)) of a physical control channel can be defined by a collection of symbol periods and can extend across the system bandwidth or a subset thereof of a carrier. One or more control regions (e.g., CORESETs) can be configured for a set of UEs 115. For example, one or more of the UEs 115 can monitor or search control regions for control information according to one or more search space sets, and each search space set can include one or multiple control channel candidates arranged in one or more aggregation levels in a cascaded manner. An aggregation level for a control channel candidate can refer to a quantity of control channel resources (e.g., control channel elements (CCEs)) associated with encoded information for a control information format having a given payload size. A search space set can include common search space sets configured for transmitting control information to multiple UEs 115 and UE-specific search space sets for transmitting control information to a specific UE 115.

[0077] A network entity 105 can provide communication coverage for a geographic area 110 via one or more cells (e.g., macro cells, small cells, hot spots, or other types of cells, or any combination thereof). The term “cell” can refer to a logical communication entity used for communication with a network entity 105 (e.g., using a carrier) and can be associated with a identifier (e.g., a physical cell identifier (PCID), a virtual cell identifier (VCID), or other cell identifier) used by a network entity 105 to distinguish one cell from another. In some examples, a cell can also refer to a coverage area 110 or a portion thereof (e.g., a sector) within which a logical communication entity operates. The coverage area 110 for such a cell can vary depending on various factors such as the capabilities of the network entity 105, and can be a small area (e.g., a structure, a subset of a structure, or a subset of a structure) or a large area (e.g., a city, a county, or a region). For example, a cell can be or include a building, a subset of a building, or an outdoor space between or overlapping coverage areas 110, among other examples.

[0078] Macrocells can generally cover a relatively large geographic area (e.g., a radius of several kilometers) and can allow unrestricted access to UEs 115 with service subscriptions with the network provider supporting the macrocell. Small cells can be associated with a lower- powered network entity 105 (e.g., a low-power base station 140) and can provide restricted or no access to UEs 115 with service subscriptions with the network provider supporting the small cell. For example, small cells can be configured to provide service only to UE 115 subscribed to a specific service plan. In some examples, small cells can be deployed in urban areas to provide additional capacity, coverage, and / or service. Throughout this disclosure, the term “cell” and its derivatives can be used to describe both individual base stations 140 and small cells associated with individual base stations 140.

[0079] In some examples, a carrier can support multiple cells, and different cells can be configured according to different protocol types (e.g., MTC, narrowband IoT (NB-IoT), enhanced mobile broadband (eMBB)) that can provide access for different types of devices.

[0080] In some examples, network entities 105 (e.g., base stations 140, RUs 170) can be mobile and thus provide communication coverage for mobile coverage areas 110. In some examples, different coverage areas 110 associated with different technologies can overlap, but different coverage areas 110 can be supported by the same network entity 105. In some other examples, overlapping coverage areas 110 associated with different technologies can be supported by different network entities 105. Wireless communication system 100 can include, for example, a heterogeneous network in which different types of network entities 105 provide coverage for various coverage areas 110 using the same or different radio access technologies.

[0081] Wireless communication system 100 can support synchronous or asynchronous operation. For synchronous operation, the network entities 105 (e.g., base stations 140) can have similar frame timings, and transmissions from different network entities 105 can be approximately aligned in time. For asynchronous operation, the network entities 105 can have different frame timings, and transmissions from different network entities 105 can not be aligned in time. The techniques described herein can be used for synchronous or asynchronous operation.

[0082] The wireless communications system 100 can be configured to support ultra-reliable communications or low-latency communications, or various combinations thereof. For example, the wireless communications system 100 can be configured to support ultra-reliable low-latency communications (URLLC). The UEs 115 can be designed to support ultra-reliable or low-latency or critical functions. Ultra-reliable communications can include private communication or group communication, and can be supported by one or more services such as push-to-talk, video, or data. Support for ultra-reliable, low-latency functions can include prioritization of services, and such services can be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, and ultra-reliable low-latency can be used interchangeably herein.

[0083] In some examples, UEs 115 can be configured to communicate directly with other UEs 115 via device-to-device (D2D) communication links 135 (e.g., according to a peer-to-peer (P2P) or D2D or sidelink protocol). In some examples, one or more UEs 115 in a group that is performing D2D communication can be within the coverage area 110 of a network entity 105 (e.g., base station 140, RU 170), which can support D2D communication for such a group configured (e.g., scheduled) by the network entity 105. In some examples, one or more UEs 115 in such a group can be outside the coverage area 110 of a network entity 105 or can otherwise be unable to receive transmissions from the network entity 105. In some examples, a group of UEs 115 communicating via D2D communications can support a one-to-many (1:M) system, where each UE 115 transmits to every other UE 115 in the group. In some examples, a network entity 105 can facilitate scheduling of resources for D2D communications. In some other examples, D2D communications can be carried out between UEs 115 without the involvement of a network entity 105.

[0084] The core network 130 can provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 can be an evolved packet core (EPC) or 5G core (5GC), which can include at least one control plane entity that can manage 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 can route packets or interconnect 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 can manage non-access stratum (NAS) functions such as mobility, authentication, and bearer management for UEs 115 served by network entities 105 associated with the core network 130. User IP packets can be transferred through the user plane entity, which can provide IP address allocation as well as other functions. The user plane entity can be connected to the IP services 150 of the one or more network operators. The IP services 150 can include access to the Internet, Intranet, an IP multimedia subsystem (IMS), or a packet-switched streaming service.

[0085] The wireless communications system 100 can operate using one or more frequency bands, 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, since the wavelengths range from approximately one decimeter to one meter in length. UHF waves can be blocked or redirected by buildings and environmental features, but the waves can penetrate structures sufficiently for a macro cell to provide service to UEs 115 located indoors. The use of UHF frequencies typically requires a higher site density than frequencies in the high frequency (HF) or very high frequency (VHF) parts of the spectrum. However, UHF frequencies can be less affected by topography than lower frequencies.

[0086] The wireless communications system 100 can utilize both licensed and unlicensed RF spectrum bands. For example, the wireless communications system 100 can employ License Assisted Access (LAA), LTE-Unlicensed (LTE-U) radio access technology, or NR technology in an unlicensed frequency spectrum band such as the 5 GHz industrial, scientific, and medical (ISM) band. When operating in unlicensed frequency spectrum bands, access points 105 and UEs 115 using LAA, LTE-U, or NR technology can perform listen-before-talk operations generating silence periods to determine whether other apparatuses are transmitting before the access points 105 or the UEs 115 transmit. In some examples, operations in unlicensed frequency spectrum bands can be based on carrier aggregation with operations in a licensed frequency spectrum band (e.g., LAA). Operations using unlicensed spectrum can include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among other examples.

[0087] The network entity 105 (e.g., base station 140, RU 170) or UE 115 can be equipped with multiple antennas, which can be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. The antennas of the network entity 105 or UE 115 can be located within one or more antenna arrays or antenna panels, which can support MIMO operations or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays can be co-located at an antenna assembly, such as an antenna tower. In some examples, the antennas or antenna arrays associated with the network entity 105 can be located at different geographic locations. The network entity 105 can include an antenna array with a set of multiple rows and multiple columns of antenna ports that the network entity 105 can use for beamforming to support communication with a UE 115. Likewise, a UE 115 can include one or more antenna arrays, which can support various MIMO or beamforming operations. Additionally or alternatively, an antenna panel can support RF beamforming for signals transmitted via the antenna ports.

[0088] Beamforming, which can also be referred to as spatial filtering, directional transmission, or directional reception, is a signal processing technique that can be used at a transmitting device or a receiving device (e.g., a network entity 105, a UE 115) to shape or steer the beam over the space. Beamforming can be achieved by combining the signals that are transmitted or received by antennas of an array of antennas. The signals transmitted or received by each antenna of the array of antennas can include a respective amplitude, phase, and / or polarization. By adjusting the amplitudes, phases, and / or polarizations of the signals transmitted or received by each of the antennas of the array of antennas, the shape and direction of the beam can be steered or shaped. The adjustments to the signals transmitted or received by each of the antennas of the array of antennas can be made in response to a channel feedback or a beam direction feedback. The channel feedback can include information about the channel between the transmitting device and the receiving device, which can be used to calculate the adjustments to the signals transmitted or received by each of the antennas of the array of antennas. The beam direction feedback can include information about the direction of the beam that is received by the receiving device, which can be used to calculate the adjustments to the signals transmitted or received by each of the antennas of the array of antennas.

[0089] The network entity 105 or UE 115 can use beam sweeping techniques as part of a beamforming operation. For example, a network entity 105 (e.g., a base station 140, a RU 170) can use multiple antennas or antenna arrays (e.g., antenna panels) to conduct a beamforming operation for directional communications with a UE 115. Some signals (e.g., synchronization signals, reference signals, beam- selection signals, or other control signals) can be transmitted by the network entity 105 multiple times in different directions. For example, the network entity 105 can transmit the signals according to different beamforming weight sets associated with different directions. Transmissions in different beam directions can be used, for example, 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 subsequent transmission or reception by the network entity 105.

[0090] Some signals, such as data signals associated with a particular receiving device, can be transmitted along a single beam direction (e.g., a direction associated with the receiving device, such as a receiving network entity 105 or a receiving UE 115) by a transmitting device (e.g., a transmitting network entity 105, a transmitting UE 115). In some examples, the beam direction associated with transmissions along a single beam direction can be determined based on a signal that was transmitted in one or more beam directions. For example, a UE 115 can receive one or more of the signals transmitted by the network entity 105 in different directions, and can report to the network entity 105 an indication of the signal received by the UE 115 with a highest signal quality or other acceptable signal quality.

[0091] In some examples, transmissions by a device (e.g., by a network entity 105 or a UE 115) can be performed using multiple beam directions, and the device can use a combination of digital precoding or beamforming to generate a combined beam for transmissions (e.g., from a network entity 105 to a UE 115). A UE 115 can report feedback that indicates precoding weights for one or more beam directions, and the feedback can correspond to a configured set of beams across a system bandwidth or one or more sub-bands. The network entity 105 can transmit a reference signal (e.g., a cell-specific reference signal (CRS), a channel state information reference signal (CSI-RS)), which can or can not be precoded. The UE 115 can provide feedback for beam selection, which can 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 the techniques are described with reference to signals transmitted by a network entity 105 (e.g., base stations 140, RUs 170) in one or more directions, a UE 115 can use similar techniques for transmitting signals multiple times in different directions (e.g., for identifying a beam direction for subsequent transmission or reception by the UE 115), or for transmitting a signal in a single direction (e.g., for transmitting data to a receiving device).

[0092] A receiving device (e.g., a UE 115) can perform reception operations according to a number of receive configurations (e.g., directional listening) when receiving various signals from a receiving device (e.g., network entity 105), such as synchronization signals, reference signals, beam selection signals, or other control signals. For example, a receiving device can perform reception according to multiple receive directions by using different antenna subarrays, by processing received signals according to different antenna subarrays, by receiving according to different receive beamforming 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, among other examples. In some examples, a receiving device can use a single receive configuration to receive signals along a single beam direction (e.g., when receiving data signals). The single receive configuration can be aligned in a beam direction determined based on listening in different receive beam directions (e.g., a beam direction determined to have the highest signal strength, highest signal-to-noise ratio (SNR), or otherwise acceptable signal quality based on listening in multiple beam directions).

[0093] Wireless communications system 100 can support UEs 115 communicating via multiple TRPs (e.g., multiple RUs 170), which can be supported by one or more network entities 105 and associated with one or more cells. For example, a UE 115 can receive signaling from multiple TRPs and can transmit a CSI report (such as a group-based measurement report) to one or more of the multiple TRPs. The CSI report can include information indicating one or more measured signal strengths (e.g., RSRPs) and information indicating one or more CMRs (e.g., reference signals) to which the measured signal strengths correspond. For example, a first TRP can transmit reference signals via a first set of CMRs while switching between different transmission beams, and a second TRP can transmit reference signals via a second set of CMRs while switching between different transmission beams. Thus, a UE 115 can indicate which reference signals have relatively greatest signal strengths through a group-based beam report. In some cases, the group-based beam report can also indicate which transmission beams are associated with the measured signal strengths (e.g., different transmission beams can correspond to different resources within a given set of CMRs).

[0094] To reduce latency during a cell handover, LTM can be utilized. For example, a serving cell can use L1 (e.g., DCI) or L2 (e.g., MAC-CE) signaling to trigger a UE 115 for a cell handover from the serving cell to a candidate cell. The candidate cell can be a dormant serving cell or a non-serving cell. In some cases, the UE 115 can be configured to measure and report reference signals from the candidate cell. For example, the candidate cell can be associated with one or more sets of CMRs, and each set of CMRs can correspond to a different TRP. That is, a first TRP can transmit reference signals using resources in a first set of CMRs, and a second TRP can transmit reference signals using resources in a second set of CMRs. The UE 115 can perform a group-based reporting by monitoring the first set of CMRs and the second set of CMRs and measuring reference signals received by the UE 115. The UE 115 can transmit a group-based beam report based on one or more measurements from the candidate cell.

[0095] In some examples, the UE 115 can transmit a group-based measurement report that indicates measurements of reference signals from the candidate cell, which can be received concurrently or simultaneously in some cases. For example, the UE 115 can measure a signal strength associated with one or more pairs of reference signals, where each pair of reference signals includes a respective first reference signal from the first set of CMRs and a respective second reference signal from the second set of CMRs. That is, each reference signal in the pair of reference signals can correspond to a different set of CMRs corresponding to the candidate cell. Additionally or alternatively, the UE 115 can perform group-based reporting for one or more additional sets of CMRs corresponding to a second cell (e.g., a serving cell or a different candidate cell). Additionally or alternatively, the first set of CMRs can correspond to the candidate cell, while the second set of CMRs can correspond to the second cell.

[0096] Figure 2 An example of a wireless communications system 200 that supports group-based beam report enhancements for LTMs is shown, in accordance with one or more aspects of the present disclosure. The wireless communications system 200 can implement aspects of the wireless communications system 100. For example, the wireless communications system 200 can include a UE 115-a, which can be an example of a UE 115 as described with reference to FIG. 1. Additionally, the wireless communications system 200 can include a candidate cell 205 and a serving cell 210, which can each be examples of a network entity 105 as described with reference to FIG. 1. Figure 1 Figure 1

[0097] As described herein, the UE 115-a can measure the candidate cell 205 and report measurements from the candidate cell for a cell handover procedure (e.g., a UE mobility procedure). For example, the UE 115-a can handover from the serving cell 210 to the candidate cell 205. To reduce latency during the cell handover, the UE 115-a, the serving cell 210, or both can use an LTM. In some cases, the LTM can involve a group-based report (e.g., a group-based measurement report 225) that includes measurements from the candidate cell 205.

[0098] ​​In some cases, UE 115-a can receive a control signal 215 from serving cell 210 indicating resources for a UE mobility procedure. For example, serving cell 210 can allocate or indicate a first set of resources (e.g., CMR set 220-a) and a second set of resources (e.g., CMR set 220-b) for UE 115-a to use for a UE mobility procedure. CMR set 220-a and CMR set 220-b can correspond to or be associated with candidate cell 205, such that candidate cell 205 is configured to use CMR sets 220 to transmit signals. That is, candidate cell 205 can be configured with multiple (in this example, two (2)) CMR sets 220, and candidate cell 205 can use multiple CMR sets 220 to transmit (or receive) signals. Although referred to as CMRs, other types of resource sets can be considered without departing from the scope of the disclosure, such as interference measurement resource (IMR) sets. For example, one or more of CMR sets 220 can be an IMR set.

[0099] In some cases, serving cell 210 can transmit control signal 215, which can include a field indicating information for the UE mobility procedure. Serving cell 210 can configure candidate cell 205 in a cell list, which can be indicated by the field. For example, the field can indicate an index of a cell list including multiple cells for the UE. Additionally or alternatively, the field can indicate a physical cell ID (PCI) of candidate cell 205. In some cases, serving cell 210 can transmit control signal 215 to UE 115-a via an L1 message (e.g., DCI), via an L2 message (e.g., MAC-CE), or via RRC.

[0100] In some cases, control signal 215 can indicate that a CSI-RS from CMR set 220 corresponds to candidate cell 205. That is, control signal 215 can indicate that CMR set 220 corresponds to candidate cell 205. For example, a candidate cell synchronization signal block (SSB) can define a transmission configuration indicator (TCI) state of the CSI-RS, which can be used by candidate cell 205 to transmit signals using CMR set 220.

[0101] In some cases, UE 115-a can perform a group-based reporting based on the set of CMRs 220 corresponding to the candidate cell 205. For example, UE 115-a can transmit a group-based measurement report 225 to the serving cell 210. UE 115-a can report one or more pairs of reference signals (which can be received via one or more overlapping time resources), and a respective RSRP (e.g., RSRP value) for each of the pairs of reference signals. In some cases, a cell identifier (e.g., cell ID) can be included in the group-based measurement report 225 to indicate the cell to which each of the reference signals corresponds, but the cell identifier can be excluded if the reference signals correspond to the same cell.

[0102] In some cases, UE 115 can include a differential report (such as a Ll-RSRP report) across multiple (e.g., all) beam groups in a CSI report. In some examples, UE 115-a can include a 1-bit indicator of the set of CMRs 220 associated with the largest RSRP value in all groups in the CSI report (where the strongest beam can be assumed to be in the first group). The 1-bit indicator can be set to “0” to indicate that the first reported CMR in each row corresponds to the first set of CMRs 220-a. Additionally or alternatively, the 1-bit indicator can be set to “1” to indicate that the first reported CMR in each row is from the second set of CMRs 220-b. Further, an uplink control information (UCI) payload partition that can be used to transmit the CSI report as a group-based measurement report 225 can have a number of bits defined or set for reporting. For example, the UCI payload partition can be set to 7 / 4 bits for the first and second CSI-RS resource indicators (CRIs) in the first beam group, and 4 bits for beams in other groups. In some cases, UE 115-a can report the number of groups N and the number of beams M per group. UE 115-a can simultaneously receive different beams within a group (e.g., pair) (e.g., via one or more overlapping time resources). The serving cell 210 can configure N via RRC or other control signaling based on a capability (e.g., UE 115-a capability) N max = {1, 2, 3, 4}.

[0103] In some cases, the group-based measurement report 225 (e.g., a Ll-RSRP report) can use 7 bits to report the RSRP of the strongest CRI (e.g., the CRI with the largest RSRP). That is, the group-based measurement report 225 can report a 7-bit RSRP of the strongest CRI (e.g., the largest RSRP reported in absolute value or full value via the 7 bits). For the remaining CRIs, the group-based measurement report 225 can report a 4-bit differential RSRP (e.g., in the range of [0, -30] dB with a step size of 2 dB) and a reference to the RSRP of the strongest CRI. Thus, the group-based measurement report 225 can reduce overhead by implementing differential reporting. In some cases, the group-based measurement report 225 can include the CRIs indexed within each CMR set 220.

[0104] Additional details of an example of UCI including the group-based measurement report 225 are illustrated by Table 1 shown below, in which N is equal to 2 and M is equal to 2. In Table 1, the CMR (e.g., reference signal) associated with the strongest or largest RSRP measurement can be in example CMR set A, which can be indicated by a first beam group (e.g., group 0). Similarly, the CMR associated with the weaker RSRP measurement can be in example CMR set B. The CMR can be a subsequent CMR in the first beam group (e.g., also indicated by the first beam group). The second beam group can include a second CMR from example CMR set A (e.g., a second strongest CRI), which can be followed by a second CMR from example CMR set B.

[0105]

[0106] Table 1: Example group-based measurement report in UCI

[0107] In some cases, each CMR set 220 can correspond to a beam from a respective TRP. Further, the CMRs in the same reporting group can correspond to different CMR sets 220. For example, the control signal 215 can allocate a first CMR set (e.g., CMR set 220-a) and a second CMR set (e.g., CMR set 220-b) to the UE 115-a. In some cases, the CMR set 220-a and the CMR set 220-b can correspond to the candidate cell 205. That is, the UE 115-a can be configured with 2 CMR sets 220 from the candidate cell 205.

[0108] In some cases, the group-based measurement report 225 associated with the candidate cell 205 can overlap with a report (e.g., a second report) from a different cell. In these cases, the UE 115-a can transmit the group-based measurement report 225 based on a priority rule for group-based reporting. For example, multiple group-based reports (e.g., the group-based measurement report 225 and the second report) from different cells can overlap in a physical uplink control channel (PUCCH). One or more events can trigger the group-based reports. In some cases, the group-based measurement report 225 for the candidate cell can be associated with a first cell identifier (cell ID) (e.g., a first candidate cell ID), and the second report can be associated with a second cell identifier (e.g., a second candidate cell ID or a serving cell ID). Group-based reports associated with the serving cell ID or the smallest candidate cell ID can have a higher priority. Thus, the UE 115-a can transmit the group-based measurement report 225 based on the first cell ID being smaller than the second cell ID.

[0109] Figure 3A and Figure 3B Examples of wireless communications systems 300-a and 300-b that support group-based beam report enhancements for LTMs in accordance with one or more aspects of the present disclosure are illustrated. The wireless communications systems 300-a and 300-b can implement aspects of the wireless communications system 100 and the wireless communications system 200. For example, the wireless communications systems 300-a and 300-b can include a candidate cell 305-a and a candidate cell 305-b, which can each be examples of a candidate cell 205 as described with reference to FIG. 1. Figure 1 Additionally, the wireless communications systems 300-a and 300-b can include one or more CMR sets 320, which can be examples of a CMR set 220 as described with reference to FIG. 1. Figure 1

[0110] In some cases, a group-based measurement report (e.g., a group-based measurement report as described herein) can be associated with (e.g., correspond to) multiple cells. In some cases, two CMR sets can correspond to each of the associated cells. For example, the group-based measurement report can correspond to the candidate cell 305-a and a second cell 310-a. The second cell 310-a can be a different candidate cell or a serving cell, which can be an example of a serving cell 210 as described with reference to FIG. 1. The serving cell can transmit control signaling indicating the resource sets 315. The resource sets 315 can be allocated to the UE for a UE mobility procedure. Figure 1

[0111] As Figure 3A ​​As illustrated, the 2 resource sets 315 correspond to each associated cell. Each resource set 315 can be associated with a set of transmit beams used for reference signals corresponding to a respective set of CMRs 320. For example, the candidate cell 305-a can transmit reference signals corresponding to the set of CMRs 320-a (e.g., for measurement by a UE) on the resource set 315-a, and can transmit reference signals corresponding to the set of CMRs 320-b on the resource set 315-b. Similarly, the second cell 310-a can transmit reference signals corresponding to the set of CMRs 320-c on the resource set 315-c, and can transmit reference signals corresponding to the set of CMRs 320-d on the resource set 315-d. That is, the set of CMRs 320-a and the set of CMRs 320-b (e.g., a first pair of sets of CMRs 320) can correspond to the candidate cell 305-a, while the set of CMRs 320-c and the set of CMRs 320-d (e.g., a second pair of sets of CMRs 320) can correspond to the second cell 310-a.

[0112] In some cases, the group-based measurement report can include multiple pairs (e.g., groups) of reference signals (e.g., beams). Different pairs of reference signals can correspond to different associated cells (e.g., the candidate cell 305-a and the second cell 310-a). For example, the group-based measurement report can include a first reference signal (e.g., CMR) from the resource set 315-a and a corresponding measurement (e.g., RSRP), a second reference signal from the resource set 315-b and a corresponding measurement, a third reference signal from the resource set 315-c and a corresponding measurement, and a fourth reference signal from the resource set 315-d and a corresponding measurement.

[0113] In some cases, each pair of reference signals included in the group-based measurement report can correspond to the same cell, while different pairs in the same report can correspond to different respective cells. That is, the group-based measurement report can correspond to multiple pairs of sets of CMRs 320. In some cases, the group-based measurement report can include a cell ID for each reported pair of reference signals.

[0114] In some cases, a UE or cell can define a priority rule for the group-based measurement report based on a respective cell ID corresponding to each of the associated cells (e.g., the candidate cell 305-a and the second cell 310-a). The smallest cell ID can have a higher priority. In some cases, a particular report (e.g., the group-based measurement report) can not include a pair of reference signals from an associated cell having the smallest cell ID.

[0115] In some cases, the candidate cell 305-a can correspond to a same frequency or a same intra- frequency measurement as the second cell 310-a. Alternatively, the candidate cell 305-a can correspond to a different frequency or a different intra- frequency measurement than the second cell 310-a. In some cases, inter- frequency measurements of associated cells (e.g., one or more candidate cells 305) from different frequencies can have different measurement gaps.

[0116] In some cases, the group-based measurement report can include reference signals from a same pair of reference signals (e.g., beams) of different cells. That is, each reference signal of the pair of reference signals can correspond to a different cell or PCI. As Figure 3B As illustrated, each resource set 315 can correspond to a different cell. That is, each resource set 315 can be associated with a set of transmission beams used for reference signals corresponding to a respective set of CMRs 320. For example, the candidate cell 305-b can transmit reference signals corresponding to the set of CMRs 320-e (e.g., for measurement by the UE) on the resource set 315-e. Similarly, the second cell 310-b can transmit reference signals corresponding to the set of CMRs 320-f on the resource set 315-f. Thus, the set of CMRs 320-e and the set of CMRs 320-f (e.g., pair of sets of CMRs 320) can correspond to both the candidate cell 305-b and the second cell 310-b (e.g., different cells), respectively.

[0117] In some cases, the set of CMRs 320 can contain reference signals corresponding to different cells. For example, the set of CMRs 320 can include reference signals from both the candidate cell 305-b and the second cell 310-b. In these cases, the UE can transmit an indication of a CMR from either the candidate cell 305-b or the second cell 310-b. In some cases, the group-based measurement report can include a reference signal identifier (RS ID) within each set of CMRs 320. Additionally or alternatively, the group-based measurement report can include an RSRP value corresponding to each reference signal.

[0118] Figure 4 A process flow 400 that supports group-based beam reporting enhancements for LTMs is shown, in accordance with one or more aspects of the present disclosure. The process flow 400 can implement or be used to facilitate or implement aspects of the wireless communications systems 100, 200, and 300 described with reference to FIG. 3. For example, the process flow 400 illustrates communications between a candidate cell 405, a UE 115-b, and a serving cell 410, which can be as described with reference to FIG. 3. Figure 1 Aspects of the wireless communications systems 100, 200, and 300 described with reference to FIG. 3. For example, the process flow 400 illustrates communications between a candidate cell 405, a UE 115-b, and a serving cell 410, which can be as described with reference to FIG. 3. Figure 1Examples of corresponding devices are illustrated by FIG. 3 and described with reference to these figures. In some implementations, the candidate cell 405 and the serving cell 410 can be associated with the network entity 105 (e.g., associated with a component of the network entity or controlled by the network entity). The process flow 400 can be implemented by the candidate cell 405, the UE 115-b, and the serving cell 410 to reduce latency and signaling overhead during a cell handover (e.g., a mobility or handoff procedure).

[0119] In the following description of the process flow 400, the operations between the candidate cell 405, the UE 115-b, and the serving cell 410 can be transmitted in a different order than the example shown, or the operations performed by the candidate cell 405, the UE 115-b, and the serving cell 410 can be performed in different orders or at different times. Some operations can also be left out of the process flow 400, and other operations can be added to the process flow 400. Moreover, although some operations or signaling are shown as occurring at different times for discussion purposes, these operations can actually be concurrent.

[0120] At 405, the serving cell 410 can transmit, to the UE 115-b, a control signal indicating a first set of resources and a second set of resources. The control signal can be an example of the control signal 215. In some aspects, the serving cell 410 can allocate the first set of resources and the second set of resources to the UE 115-b for group-based channel measurement reporting by the UE 115-b for a UE mobility procedure. Additionally, the serving cell 410 can indicate that the first set of resources and the second set of resources can be associated with the candidate cell 405. Figure 2

[0121] At 410, the candidate cell 405 can transmit a reference signal to the UE 115-b. For example, the candidate cell 405 can transmit the reference signal using resources in the first set of resources and the second set of resources. In some cases, the reference signal can include a first subset of reference signals (e.g., first reference signals) associated with the first set of resources and a second subset of reference signals (e.g., second reference signals) associated with the second set of resources. Additionally, the first set of resources can correspond to a first set of CMRs and the second set of resources can correspond to a second set of CMRs. The candidate cell 405 can transmit the first subset of reference signals and the second subset of reference signals concurrently (e.g., via one or more time resources that at least partially overlap in time).

[0122] ​At 415, UE 115-b can monitor the first resource set and the second resource set. For example, UE 115-b can monitor the first resource set and the second resource set to find a reference signal from candidate cell 405. In some cases, UE 115-b can measure the reference signal to obtain its corresponding RSRP value.

[0123] At position 420, UE 115-b can send a group-based measurement report to serving cell 410. This group-based measurement report can be about... Figure 2 An example of group-based measurement report 225. In some cases, the group-based measurement report may be associated with at least candidate cell 405. For example, the group-based measurement report may indicate measurements (e.g., RSRP values) associated with a reference signal from candidate cell 405. In some examples, the group-based measurement report may also indicate which transmit beams are associated with the measured reference signal (e.g., different transmit beams may correspond to different resources within a given CMR set).

[0124] At 425, serving cell 410 may send a control message to UE 115-b. For example, the control message may instruct UE 115-b to switch its coverage from serving cell 410 to candidate cell 405 during a UE mobility procedure (e.g., a handover procedure).

[0125] Figure 5 A block diagram 500 of a device 505 supporting group-based beam reporting enhancement for LTM, according to one or more aspects of this disclosure, is shown. Device 505 may be an example of various aspects of UE 115 as described herein. Device 505 may include an input component 510, an output component 515, and a communication manager 520. Device 505 may also include a processor. Each of these components may communicate with each other (e.g., via one or more buses).

[0126] Input component 510 manages input signals of device 505. For example, input component 510 may identify input signals based on interaction with a modem, keyboard, mouse, touchscreen, or similar device. These input signals may be associated with user input or processing at other components or devices. In some cases, input component 510 may utilize an operating system (such as...) The input component 510 may transmit aspects of these input signals to other components of the device 505 for processing. For example, the input component 510 may send input signals to the communication manager 520 to support group-based beam reporting enhancement for LTM. In some cases, the input component 510 may be as described in the reference... Figure 8 The components of the described input / output (I / O) controller 810.

[0127] The output component 515 can manage output signals for the device 505. For example, the output component 515 can receive signals from other components of the device 505, such as the communication manager 520, and can send these signals to other components or devices. In some particular examples, the output component 515 can send output signals for display in a user interface, for storage in a database or data repository, for further processing at a server or server cluster, or for any other process at any number of devices or systems. In some cases, the output component 515 can be a component of the I / O controller 810 as described with reference to FIG. 8. Figure 8

[0128] The communication manager 520, the input component 510, the output component 515, or various combinations or components thereof can be examples of means for performing various aspects of group-based beam report enhancements for LTMs as described herein. For example, the communication manager 520, the input component 510, the output component 515, or various combinations or components thereof can support a method for performing one or more of the functions described herein.

[0129] In some examples, the communication manager 520, the input component 510, the output component 515, or various combinations or components thereof can be implemented in hardware (e.g., in a communication management circuit). The hardware can include 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 microcode controller, a discrete gate or transistor logic, discrete hardware components, or any combination thereof designed to perform the functions described in the present disclosure. In some examples, a processor and memory coupled with the processor can be configured to perform one or more of the functions described herein (e.g., by executing instructions stored in memory).

[0130] Additionally or alternatively, in some examples, the communication manager 520, the input component 510, the output component 515, or various combinations or components thereof can be implemented in code (e.g., as communication management software or firmware) executed by a processor. If implemented in code executed by a processor, the functions of the communication manager 520, the input component 510, the output component 515, or various combinations or components thereof can be executed 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.

[0131] ​In some examples, the communication manager 520 can be configured to use or otherwise coordinate with the input component 510, the output component 515, or both, to perform various operations (e.g., receiving, obtaining, monitoring, outputting, transmitting) described herein. For example, the communication manager 520 can receive information from the input component 510, transmit information to the output component 515, or integrate with the input component 510, the output component 515, or both, to obtain information, output information, or perform various other operations as described herein.

[0132] The communication manager 520 can support wireless communication at a UE in accordance with examples as disclosed herein. For example, the communication manager 520 can be, be configured to, or be operable to support means for receiving a control signal indicating a first set of resources and a second set of resources allocated to the UE for group-based channel measurement reporting for a UE mobility procedure, where the first set of resources and the second set of resources are both associated with a candidate cell for the UE mobility procedure. The communication manager 520 can be, be configured to, or be operable to support means for monitoring the first set of resources and the second set of resources for a set of multiple reference signals associated with the candidate cell in accordance with the UE mobility procedure, the set of multiple reference signals including a first subset of reference signals associated with the first set of resources and a second subset of reference signals associated with the second set of resources. The communication manager 520 can be, be configured to, or be operable to support means for transmitting a group-based measurement report for the candidate cell indicating one or more measurements of the set of multiple reference signals associated with the candidate cell based on monitoring the first set of resources and the second set of resources.

[0133] Additionally or alternatively, the communications manager 520 can support wireless communication at a UE in accordance with examples as disclosed herein. For example, the communications manager 520 can enable, be configured as, or be operable to support means for receiving a control signal indicating a first set of resources and a second set of resources allocated to the UE for group-based channel measurement reporting for a UE mobility procedure, where the first set of resources is associated with a candidate cell for the UE mobility procedure and the second set of resources is associated with a second cell for the UE mobility procedure. The communications manager 520 can enable, be configured as, or be operable to support means for monitoring the first set of resources for a first set of reference signals associated with the candidate cell and the second set of resources for a second set of reference signals associated with the second cell in accordance with the UE mobility procedure. The communications manager 520 can enable, be configured as, or be operable to support means for transmitting a group-based measurement report indicating one or more measurements of the first set of reference signals associated with the candidate cell and one or more measurements of the second set of reference signals associated with the second cell based on monitoring the first set of resources and the second set of resources.

[0134] By including or configuring the communications manager 520 in accordance with examples as described herein, the device 505 (e.g., a processor of the control input component 510, the output component 515, the communications manager 520, or a combination or otherwise of them coupled with a processor) can support a technique for reducing latency associated with a cell handover by enabling the device 505 to obtain measurements of multiple candidate cell resource sets, which can be used for handover or cell switching.

[0135] Figure 6 A block diagram 600 of a device 605 that supports group-based beam report enhancements for LTMs is shown, in accordance with one or more aspects of the present disclosure. The device 605 can be an example of aspects of a device 505 or a UE 115 as described herein. The device 605 can include an input component 610, an output component 615, and a communications manager 620. The device 605 can also include a processor. Each of these components can be in communication with one another (e.g., via one or more buses).

[0136] The input component 610 can manage input signals for the device 605. For example, the input component 610 can identify input signals based on interactions with a modem, a keyboard, a mouse, a touchscreen, or similar devices. These input signals can be associated with user inputs or processes at other components or devices. In some cases, the input component 610 can utilize an operating system, such as iOS®, ANDROID®, PHON or another known operating system. Input component 610 can transmit aspects of these input signals to other components of device 605 for processing. For example, input component 610 can send input signals to communication manager 620 to support group-based beam report enhancements for LTMs. In some cases, input component 610 can be a component of I / O controller 810 as described with reference to Figure 8

[0137] Output component 615 can manage output signals for device 605. For example, output component 615 can receive signals from other components of device 605, such as communication manager 620, and can send these signals to other components or devices. In some particular examples, output component 615 can send output signals for display in a user interface, for storage in a database or data repository, for further processing at a server or cluster of servers, or for any other process at any number of devices or systems. In some cases, output component 615 can be a component of I / O controller 810 as described with reference to Figure 8

[0138] Device 605 or its various components can be an example of means for performing various aspects of group-based beam report enhancements for LTMs as described herein. For example, communication manager 620 can include resource indication component 625, resource monitoring component 630, group-based measurement reporting component 635, or any combination thereof. Communication manager 620 can be an example of aspects of communication manager 520 as described herein.

By way of example, and not limitation, non-transitory computer-readable media can 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 can be used to carry or store desired program code means in the form of instructions or data structures and that can be accessed by a general-purpose or special-purpose computer, or a general-purpose or special-purpose processor. Also, any connection is properly termed a computer-readable medium. For example, if the software is transmitted from a website, server, or other remote source using a coaxial cable, fiber optic cable, twisted pair, digital subscriber line (DSL), or wireless technologies such as infrared, radio, and microwave, then the coaxial cable, fiber optic cable, twisted pair, DSL, or wireless technologies such as infrared, radio, and microwave are included in the definition of computer-readable medium. Disk and disc, as used herein, include CD, laser disc, optical disc, digital versatile disc (DVD), floppy disk and Blu-ray disc where disks usually reproduce data magnetically, while discs reproduce data optically with lasers. Combinations of the above are also included within the scope of computer-readable media.

[0268] As used herein, including in the claims,“or” as used in a list of items (for example, 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” can 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.”

[0269] The term“determining” encompasses a wide variety of actions and, therefore,“determining” can include calculating, computing, processing, deriving, investigating, looking up (such as via a table, a database, or another data structure), ascertaining and the like. Also,“determining” can include receiving (such as receiving information), accessing (such as accessing data in a memory), and the like. Also, “determining” can include resolving, selecting, choosing, establishing, and other such similar actions.

[0270] In the drawings, like reference numerals can be used to denote similar components throughout the several views. Further, components of the same type can be distinguished by following the reference numeral with a dashed line and a second label wherein the second label distinguishes among the group of similar components. If only the first reference numeral is used in the specification, the description is applicable to any one of the similar components having the same first reference numeral irrespective of the second reference numeral or other subsequent reference numerals.

[0271] The description set forth herein, in connection with the appended drawings, describes example configurations and does not represent all the examples that can be implemented or that are within the scope of the claims. The term“example” as 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, can be practiced without these specific details. In some instances, well-known structures and devices are shown in block diagram form in order to avoid obscuring the concepts of the described examples.

[0272] The description herein is presented to enable any person skilled in the art to practice the present disclosure. Various modifications to the disclosure can be made by persons skilled in the art, and the disclosure is not limited to the examples described herein, which are intended as illustrations of the present principles and novel features. Hence, the disclosure is not limited to the examples described herein, but the scope of the disclosure is to be accorded the broadest range of interpretative scope consistent with the principles and novel features disclosed.
