Description

Technical Field

[0001] The following relates to wireless communications, including predictive beam management across serving cells. Background Art

[0002] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcast, and the like. These systems may be able to 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, advanced LTE (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 techniques 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 communication system may include one or more base stations, each of which supports wireless communication of communication devices, which may be referred to as user equipment (UE). In some wireless communication systems, a UE may perform predictive channel quality measurements in a first serving cell. The UE may also be mobile and may move between various serving cells. Summary of the Invention

[0003] The described technology relates to improved methods, systems, devices, and apparatuses for supporting predictive beam management across serving cells. For example, the described technology provides a cross-serving cell solution that enables a user equipment (UE) (e.g., located in a first serving cell) to perform predictive channel quality measurements for a second serving cell and report these measurements in a channel state information (CSI) report for the first serving cell. The UE may receive a CSI report information message from a network entity that identifies a first set of actual resources corresponding to a first set of beams and a second set of resources (e.g., virtual resources) corresponding to a second set of beams. The UE may use the first set of beams to perform channel quality measurements via the first set of resources and may perform channel quality measurement prediction for the second set of resources for the second set of beams. The network entity may indicate the association between the first set of resources and the second set of resources in the CSI report information message, for example, by using code points in a codebook configured by radio resource control (RRC) at the second serving cell. In some examples, the UE may send a CSI report to the network entity in the first serving cell, the CSI report including predicted measurements for the second serving cell (e.g., for the second set of beams).

[0045] In some wireless communication systems, a user equipment (UE) may report measurements associated with one or more resources (channel measurement resources (CMRs)) used for communications between the UE and the network entity to a network entity in a channel state information (CSI) report. The CSI report may indicate channel quality information or beam information based on which the network entity may schedule or configure subsequent communications. The UE may perform CSI measurements via a first set of resources using a first set of beams (set A beams) and may generate a CSI report that includes predicted CSI measurements for a second set of resources using a second set of beams (set B beams) linked to the first set of resources within a given cell (e.g., a first serving cell). In some examples, the first set of resources may be actual resources and the second set of resources may be virtual resources. The UE may be mobile and may change its geographic location over time (e.g., may be switched from a first cell to a second cell). CSI measurements and predictions in one cell may not be applicable to a second serving cell, or where one or more beams may be used in multiple cells, it may be inefficient to re-perform beam measurements and CSI reporting in each cell (e.g., as part of or after a mobility procedure).

[0046] In some cases, the UE may support enhanced signaling to include predicted CSI measurements for a second cell in a CSI report for a first cell. Resources (e.g., a first set and a second set of resources for generating predicted CSI measurements) may be defined with reference to the second cell, but the CSI report may be configured by the first cell, the second cell, or both, and may be triggered by the first serving cell and reported to the first serving cell. In some examples, the resources used for CSI measurements in the first cell and the resources used for CSI measurements in the second cell may be configured as a set of resources identified by an identifier of the second serving cell (e.g., in a CSI report configuration provided by the first cell, the set of resources used to predict CSI measurements in the second cell may be indicated by and associated with the cell identifier of the second serving cell). In some examples, the first serving cell may provide CSI report information for the first serving cell, which may include one or more sets of resources, wherein each resource used for CSI measurement in the second serving cell is individually identified by an identifier of the second serving cell. In some cases, the UE may report capability information indicating that the UE is capable of supporting cross-serving cell predictive CSI reporting, and may be configured for cross-serving cell predictive CSI reporting based on this capability information.

[0047] By including the predicted CSI measurement for the second cell in the CSI report for the first cell, the UE can reduce the delay associated with UE mobility or switching serving cells. For example, the UE can reduce the time delay associated with performing new channel measurements based on switching from the first cell to the second cell. The UE can instead perform channel quality measurements corresponding to communications in the second serving cell in advance and thereby reduce the communication delay associated with communications with the network entity in the second cell. In some cases, the UE can perform channel measurements related to communications in the second serving cell in the first serving cell, and the UE can apply resources to communications in the second serving cell without performing new measurements, which can reduce redundancy in measurements or processes and support more efficient utilization of resources.

[0048] Various aspects of the present disclosure are first described in the context of a wireless communication system. Aspects of the present disclosure are further described in the context of a channel measurement scheme, CSI reporting configuration, and process flow. Aspects of the present disclosure are further illustrated and described with reference to apparatus diagrams, system diagrams, and flow diagrams related to cross-serving cell predictive beam management.

[0049] Figure 1An example of a wireless communication system 100 that supports predictive beam management across serving cells according to one or more aspects of the present disclosure is illustrated. The wireless communication system 100 may include one or more network entities 105, one or more UEs 115, and a core network 130. In some examples, the wireless communication system 100 may be a Long Term Evolution (LTE) network, an Advanced LTE (LTE-A) network, an LTE-A Pro network, a New Radio (NR) network, or a network operating according to other systems and radio technologies, including future systems and radio technologies not explicitly mentioned herein.

[0050] The network entities 105 may be dispersed throughout a geographic area to form the wireless communication system 100 and may include devices that take different forms or have different capabilities. In various examples, the network entities 105 may 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 may communicate wirelessly via one or more communication links 125 (e.g., radio frequency (RF) access links). For example, the network entities 105 may support a coverage area 110 (e.g., a geographic coverage area) within which the UEs 115 and the network entities 105 may establish one or more communication links 125. The coverage area 110 may be an example of a geographic area within which the network entities 105 and the UEs 115 may support signaling according to one or more radio access technologies (RATs).

[0051] The UEs 115 may be dispersed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 may be stationary or mobile or both stationary and mobile at different times. The UEs 115 may be devices that take different forms or have different capabilities. Figure 1 Some example UEs 115 are illustrated in FIG. The UEs 115 described herein may be capable of supporting communication with various types of devices such as Figure 1 Other UEs 115 or network entities 105 are shown communicating.

[0052] As described herein, a node of the wireless communication system 100 (which may be referred to as a network node or 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, the node may be a UE 115. As another example, the 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 other aspects of this example, the first node, the second node, and the third node may be different relative to these examples. Similarly, reference to UE 115, network entity 105, apparatus, device, or computing system may include disclosure that UE 115, network entity 105, apparatus, device, or computing system is a node. For example, a disclosure that UE 115 is configured to receive information from network entity 105 also discloses that the first node is configured to receive information from a second node.

[0053] In some examples, network entities 105 can communicate with core network 130, or with each other, or both. For example, network entities 105 can communicate with core network 130 via one or more backhaul communication links 120 (e.g., according to S1, N2, N3, or other interface protocols). In some examples, network entities 105 can communicate with each other via backhaul communication links 120 (e.g., according to X2, Xn, or other interface protocols), either directly (e.g., directly between network entities 105) or indirectly (e.g., via core network 130). In some examples, network entities 105 can communicate with each other via midhaul communication links 162 (e.g., according to a midhaul interface protocol) or fronthaul communication links 168 (e.g., according to a fronthaul interface protocol), or any combination thereof. Backhaul communication links 120, midhaul communication links 162, or fronthaul communication links 168 can be or include one or more wired links (e.g., electrical links, fiber optic links), one or more wireless links (e.g., radio links, wireless optical links), etc., or various combinations thereof. UE 115 may communicate with core network 130 via communication link 155 .

[0054] One or more of the network entities 105 described herein may include or may 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 Node B, an eNodeB (eNB), a next-generation Node B, or a gigabit Node B (any of which may be referred to as a gNB), a 5G NB, a next-generation eNB (ng-eNB), a Home Node B, a Home evolved Node B, or other suitable terminology). In some examples, the network entity 105 (e.g., a base station 140) may be implemented in a converged (e.g., monolithic, standalone) base station architecture that may be configured to utilize a protocol stack that is physically or logically integrated within a single network entity 105 (e.g., a single RAN node, such as the base station 140).

[0055] 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 that is physically or logically distributed between 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 the following: 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 may also be referred to as a radio head, smart radio head, remote radio head (RRH), remote radio unit (RRU), or transmit receive point (TRP). One or more components of the network entity 105 in the disaggregated RAN architecture may be co-located, or one or more components of the network entity 105 may be located in distributed locations (e.g., separate physical locations). In some examples, one or more network entities 105 of the disaggregated RAN architecture may be implemented as virtual units (e.g., virtual CU (VCU), virtual DU (VDU), virtual RU (VRU)).

[0056] The functional split between CU 160, DU 165, and RU 170 is flexible and can support different functionalities depending on which functions (e.g., network layer functions, protocol layer functions, baseband functions, RF functions, and any combination thereof) are performed at CU 160, DU 165, or RU 170. For example, a functional split of the protocol stack can be employed between CU 160 and DU 165 such that CU 160 can support one or more layers of the protocol stack and DU 165 can support one or more different layers of the protocol stack. In some examples, 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 may be connected to one or more DUs 165 or RUs 170, and the one or more DUs 165 or RUs 170 may host lower protocol layers, such as Layer 1 (L1) (e.g., physical (PHY) layer) or L2 (e.g., radio link control (RLC) layer, 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 the DU 165 and the 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 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 may be within the protocol layer (e.g., some functions of the protocol layer may be performed by one of the CU 160, DU 165, or RU 170, while other functions of the protocol layer may be performed by a different one of the CU 160, DU 165, or RU 170). The CU 160 may be further functionally split into CU control plane (CU-CP) and CU user plane (CU-UP) functions. The CU 160 may be connected to one or more DUs 165 via midhaul communication links 162 (e.g., F1, F1-c, F1-u), and the DU 165 may be connected to one or more RUs 170 via fronthaul communication links 168 (e.g., an open fronthaul (FH) interface). In some examples, midhaul communication link 162 or fronthaul communication link 168 may be implemented according to an interface (e.g., a channel) between layers of a protocol stack supported by respective network entities 105 that communicate via such communication links.

[0057] In some wireless communication systems (e.g., wireless communication system 100), the infrastructure and spectrum resources for radio access may support wireless backhaul link capabilities to supplement wired backhaul connections, thereby providing an IAB network architecture (e.g., to the core network 130). In some cases, in an IAB network, one or more network entities 105 (e.g., IAB nodes 104) may be partially controlled by each other. One or more IAB nodes 104 may be referred to as a donor entity or IAB donor. One or more DUs 165 or one or more RUs 170 may 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) may 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). The IAB node 104 may include an IAB mobile terminal (IAB-MT) controlled (e.g., scheduled) by the DU 165 of the coupled IAB donor. The IAB-MT may include an independent set of antennas for relaying communications with the UE 115, or may share the same antennas of the IAB node 104 (e.g., of the RU 170) for access via the DU 165 of the IAB node 104 (e.g., referred to as a virtual IAB-MT (vIAB-MT)). In some examples, the IAB node 104 may include a DU 165 that supports communication links with additional entities (e.g., IAB node 104, UE 115) within a relay chain or configuration (e.g., downstream) of the access network. In such cases, one or more components of the decomposed RAN architecture (e.g., one or more IAB nodes 104 or components of the IAB node 104) may be configured to operate according to the techniques described herein.

[0058] For example, an access network (AN) or RAN may include communications between an access node (e.g., an IAB donor), an IAB node 104, and one or more UEs 115. The IAB donor may facilitate connectivity between the core network 130 and the AN (e.g., via a wired or wireless connection to the core network 130). That is, the IAB donor may refer to a RAN node that has a wired or wireless connection to the core network 130. The IAB donor may include a CU 160 and at least one DU 165 (e.g., and RU 170), wherein the CU 160 may communicate with the core network 130 via an interface (e.g., a backhaul link). The IAB donor and the IAB node 104 may communicate via the F1 interface according to a protocol that defines signaling messages (e.g., the F1 AP protocol). Additionally or alternatively, CU 160 may communicate with the core network via an interface (which may be an example of a portion of a backhaul link) and may communicate with other CUs 160 (e.g., CUs 160 associated with alternative IAB donors) via an Xn-C interface (which may be an example of a portion of a backhaul link).

[0059] An IAB node 104 may refer to a RAN node that provides IAB functionality (e.g., access for UE 115, wireless self-backhaul capabilities, etc.). The DU 165 may act as a distributed scheduling node toward child nodes associated with the IAB node 104, and the IAB-MT may act as a scheduled node toward a parent node associated with the IAB node 104. That is, an IAB donor may be referred to as a parent node that communicates with one or more child nodes (e.g., the IAB donor may relay transmissions for UEs through one or more other IAB nodes 104). Additionally or alternatively, depending on the relay chain or configuration of the AN, the IAB node 104 may also be referred to as a parent node or child node of other IAB nodes 104. Thus, the IAB-MT entity of the IAB node 104 may provide a Uu interface for the child IAB node 104 to receive signaling from the parent IAB node 104 , and a DU interface (eg, DU 165 ) may provide a Uu interface for the parent IAB node 104 to signal to the child IAB node 104 or the UE 115 .

[0060] For example, IAB node 104 may be referred to as a parent node supporting communications for child IAB nodes, or as a child node associated with an IAB donor, or both. The IAB donor may include a CU 160 having a wired or wireless connection to the core network 130 (e.g., backhaul communication link 120) and may serve as a parent node for IAB node 104. For example, the DU 165 of the IAB donor may relay transmissions to UE 115 via IAB node 104, or may directly signal the transmissions to UE 115, or both. The CU 160 of the IAB donor may signal the establishment of a communication link to IAB node 104 via the F1 interface, and IAB node 104 may schedule transmissions (e.g., transmissions relayed from the IAB donor to UE 115) via the DU 165. That is, data may be relayed to and from IAB node 104 via signaling via the NR Uu interface of the MT to IAB node 104. Communications with the IAB node 104 may be scheduled by the DU 165 of the IAB donor, and communications with the IAB node 104 may be scheduled by the DU 165 of the IAB node 104 .

[0061] Where the techniques described herein are applied in the context of a disaggregated RAN architecture, one or more components of the disaggregated RAN architecture may be configured to support cross-cell predictive beam management as described herein. For example, some operations described as being performed by the UE 115 or the network entity 105 (e.g., the base station 140) may additionally or alternatively be performed by one or more components of the disaggregated RAN architecture (e.g., the IAB node 104, the DU 165, the CU 160, the RU 170, the RIC 175, the SMO 180).

[0062] UE 115 may include or may be referred to as a mobile device, wireless device, remote device, handheld device, or subscriber device, or some other suitable terminology, where "device" may also be referred to as a unit, station, terminal, client, or the like. UE 115 may also include or 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, MP3 player, or video device), a camera, a gaming device, a navigation / positioning device (e.g., a GNSS (Global Navigation Satellite System) device based on, for example, GPS (Global Positioning System), BeiDou, GLONASS, or Galileo systems, ground-based equipment, etc.), 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 vehicle's equipment, a meter (e.g., a parking meter, an electricity meter, a gas meter, a water meter), a monitor, a gas pump, an appliance (e.g., a kitchen appliance, a washer, a 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, 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 communication (MTC) device, etc., which may be implemented in various objects such as appliances or vehicles, meters, etc.

[0063] The UE 115 described herein may be capable of communicating with various types of devices, such as other UEs 115, which may sometimes act as relays, as well as network entities 105 and network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, etc. Figure 1 shown.

[0064] The UE 115 and the network entity 105 may wirelessly communicate with each other via one or more communication links 125 (e.g., access links) using resources associated with one or more carriers. The term "carrier" may refer to a collection of RF spectrum resources having a physical layer structure defined for supporting the communication link 125. For example, a carrier used for the communication link 125 may include a portion of an RF spectrum band (e.g., a bandwidth part (BWP)) that operates 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 may carry acquisition signaling (e.g., synchronization signals, system information), control signaling for coordinating carrier operation, user data, or other signaling. The wireless communication system 100 may support communications with the UE 115 using carrier aggregation or multi-carrier operation. Depending on the carrier aggregation configuration, the UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation may be used for both frequency division duplex (FDD) and time division duplex (TDD) component carriers. Communication between the network entity 105 and other devices may refer to communication between those devices and any portion (e.g., entity, sub-entity) of the network entity 105. For example, the terms "send," "receive," or "communicate" when referring to the network entity 105 may refer to any portion of the network entity 105 (e.g., base station 140, CU 160, DU 165, RU 170) of the RAN communicating with another device (e.g., directly or via one or more other network entities 105).

[0065] The signal waveform transmitted via the carrier may include multiple subcarriers (e.g., using a multicarrier modulation (MCM) technique 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 the 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 amount 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 amount of resource elements (e.g., in the transmission duration) and a relatively higher modulation scheme order may correspond to a relatively higher communication rate. Wireless communication resources may refer to a combination of RF spectrum resources, time resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial resources may increase the data rate or data integrity used for communication with UE 115.

[0066] The time interval for the network entity 105 or the UE 115 may be expressed as a multiple of a basic time unit, which may be, for example, a sampling period T s =1 / (Δf max·N f ) seconds, where Δf max It can represent the supported subcarrier spacing, and N f The supported discrete Fourier transform (DFT) size may be indicated. Time intervals of communication resources 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).

[0067] Each frame may include a plurality of consecutively numbered subframes or time slots, and each subframe or time 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 certain number of time slots. Alternatively, each frame may include a variable number of time slots, and the amount of time slots may depend on the subcarrier spacing. Each time slot may include a certain number of symbol periods (e.g., depending on the length of the cyclic prefix appended to the front of each symbol period). In some wireless communication systems 100, the time slot may be further divided into a plurality of mini-slots associated with one or more symbols. Excluding the cyclic prefix, each symbol period may be associated with one or more (e.g., N f The duration of a symbol period may depend on the subcarrier spacing or the operating frequency band.

[0068] A subframe, slot, mini-slot, or symbol may be the smallest scheduling unit (e.g., in the time domain) of the wireless communication system 100 and may be referred to as a Transmit Time Interval (TTI). In some examples, the TTI duration (e.g., the number of symbol periods in a TTI) may be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 may be dynamically selected (e.g., in bursts of shortened TTIs (sTTIs)).

[0069] According to various techniques, physical channels may be multiplexed using carriers for communication. Physical control channels and physical data channels may be multiplexed for signaling over downlink carriers, for example, using one or more of time division multiplexing (TDM), frequency division multiplexing (FDM), or hybrid TDM-FDM techniques. A control region (e.g., a control resource set (CORESET)) of a physical control channel may be defined by a set of symbol periods and may extend across the system bandwidth of a carrier or a subset of the system bandwidth. One or more control regions (e.g., CORESETs) may be configured for a set of UEs 115. For example, one or more of UEs 115 may monitor or search the control region for control information according to one or more search space sets, and each search space set may include one or more control channel candidates in one or more aggregation levels arranged in a cascaded manner. The aggregation level of a control channel candidate may refer to the amount of control channel resources (e.g., control channel elements (CCEs)) associated with coded information for a control information format having a given payload size. The search space sets may include a common search space set configured for transmitting control information to multiple UEs 115 and a UE-specific search space set for transmitting control information to a specific UE 115 .

[0070] The network entity 105 may provide communication coverage via one or more cells (e.g., macro cells, small cells, hotspots, or other types of cells, or any combination thereof). The term "cell" may refer to a logical communication entity used to communicate with the network entity 105 (e.g., using a carrier) and may be associated with an identifier (e.g., a physical cell identifier (PCID), a virtual cell identifier (VCID), or other identifier) ​​used to distinguish between adjacent cells. In some examples, a cell may also refer to a coverage area 110 or a portion of a coverage area 110 (e.g., a sector) within which the logical communication entity operates. Depending on various factors (such as the capabilities of the network entity 105), such cells may range from a smaller area (e.g., a structure, a subset of a structure) to a larger area. For example, a cell may be or may include a building, a subset of a building, or an external space between or overlapping coverage areas 110, etc.

[0071] A macro cell typically covers a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access to UEs 115 that have a service subscription with a network provider that supports the macro cell. Small cells may be associated with lower-power network entities 105 (e.g., lower-power base stations 140) than macro cells, and may operate using the same or different (e.g., licensed, unlicensed) frequency bands as the macro cells. Small cells may provide unrestricted access to UEs 115 that have a service subscription with the network provider, or may provide restricted access to UEs 115 associated with the small cell (e.g., UEs 115 in a closed subscriber group (CSG), UEs 115 associated with users in a home or office). A network entity 105 may support one or more cells and may also support communication via one or more cells using one or more component carriers.

[0072] In some examples, a carrier may support multiple cells, and different cells may be configured according to different protocol types (e.g., MTC, narrowband IoT (NB-IoT), enhanced mobile broadband (eMBB)) that may provide access to different types of devices.

[0073] In some examples, network entities 105 (e.g., base stations 140, RUs 170) can be mobile and, therefore, provide communication coverage for mobile coverage areas 110. In some examples, different coverage areas 110 associated with different technologies can overlap, but the 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. The 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.

[0074] The wireless communication system 100 may support synchronous or asynchronous operation. For synchronous operation, the network entities 105 (e.g., base stations 140) may have similar frame timing, and transmissions from different network entities 105 may be approximately aligned in time. For asynchronous operation, the network entities 105 may have different frame timing, and in some examples, transmissions from different network entities 105 may not be aligned in time. The techniques described herein may be used for either synchronous or asynchronous operation.

[0075] The wireless communication system 100 can be configured to support ultra-reliable communication or low-latency communication or various combinations thereof. For example, the wireless communication system 100 can be configured to support ultra-reliable low-latency communication (URLLC). The UE 115 can be designed to support ultra-reliable or low-latency or critical functions. Ultra-reliable communication can include private 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" are used interchangeably herein.

[0076] In some examples, a UE 115 can be configured to support communication directly with other UEs 115 via a device-to-device (D2D) communication link 135 (e.g., according to a peer-to-peer (P2P), D2D, or sidelink protocol). In some examples, one or more UEs 115 in a group performing D2D communication can be within a coverage area 110 of a network entity 105 (e.g., a base station 140, a RU 170), which can support aspects of such D2D communication configured by the network entity 105 (e.g., scheduled by the network entity). In some examples, one or more UEs 115 in such a group can be outside the coverage area 110 of the network entity 105 or can otherwise be unable or not configured to receive transmissions from the network entity 105. In some examples, a group of UEs 115 communicating via D2D communication can support a one-to-many (1:M) system, in which each UE 115 transmits to each of the other UEs 115 in the group. In some examples, network entity 105 may facilitate scheduling of resources for D2D communications. In some other examples, D2D communications may be performed between UEs 115 without involving network entity 105.

[0077] 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 a 5G core (5GC), which may include at least one control plane entity (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) for managing access and mobility and at least one user plane entity (e.g., a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), or a user plane function (UPF)) for routing packets or interconnecting to external networks. The control plane entity may manage non-access stratum (NAS) functions such as mobility, authentication, and bearer management for UEs 115 served by network entities 105 (e.g., base stations 140) associated with the core network 130. User IP packets may be delivered through the user plane entity, which may provide IP address allocation and other functions. The user plane entity may be connected to the IP services 150 of one or more network operators. IP services 150 may include access to the Internet, an intranet, an IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0078] The wireless communication system 100 can operate using one or more frequency bands that can range from 300 megahertz (MHz) to 300 gigahertz (GHz). Generally speaking, the region from 300 MHz to 3 GHz is referred to as the ultra-high frequency (UHF) region or decimeter band because the wavelengths range from about one decimeter to one meter in length. UHF waves can be blocked or redirected by buildings and environmental features (which can be referred to as clusters), but these waves can penetrate structures sufficiently for a macro cell to provide service to a UE 115 located indoors. Communication using UHF waves can be associated with smaller antennas and a shorter range (e.g., less than 100 kilometers) than communication using the lower frequencies and longer waves in the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.

[0079] The wireless communication system 100 can utilize licensed and unlicensed RF spectrum bands. For example, the wireless communication system 100 can use unlicensed bands (such as the 5 GHz Industrial, Scientific, and Medical (ISM) band) to employ Licensed Assisted Access (LAA), LTE Unlicensed (LTE-U) radio access technology, or NR technology. When operating using unlicensed RF spectrum bands, devices such as the network entity 105 and the UE 115 can employ carrier sensing for conflict detection and avoidance. In some examples, operations using unlicensed bands can be based on carrier aggregation configuration (e.g., LAA) in combination with component carriers operating using licensed bands. Operations using unlicensed spectrum can include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among others.

[0080] A network entity 105 (e.g., a base station 140, a RU 170) or a UE 115 may be equipped with multiple antennas that can be used to employ techniques such as transmit diversity, receive diversity, multiple-input, multiple-output (MIMO) communications, or beamforming. The antennas of the network entity 105 or 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, the antennas or antenna arrays associated with the network entity 105 may be located at different geographical locations. The network entity 105 may include an antenna array having a set of multiple rows and columns of antenna ports that the network entity 105 can use to support beamforming for communications with the UE 115. Similarly, the UE 115 may include one or more antenna arrays that may support various MIMO or beamforming operations. Additionally or alternatively, the antenna panels may support RF beamforming for signals transmitted via the antenna ports.

[0081] The network entity 105 or the UE 115 may use MIMO communication to exploit multipath signal propagation and improve spectral efficiency by sending or receiving multiple signals via different spatial layers. Such a technique may be referred to as spatial multiplexing. The multiple signals may be sent, for example, by a transmitting device via different antennas or different combinations of antennas. Similarly, the multiple signals may be received by a receiving device via different antennas or different combinations of antennas. Each of the multiple signals may be referred to as a separate spatial stream and may carry information associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers may be associated with different antenna ports for channel measurement and reporting. MIMO techniques include single-user MIMO (SU-MIMO), in which multiple spatial layers are transmitted to the same receiving device, and multi-user MIMO (MU-MIMO), in which multiple spatial layers are transmitted to multiple devices.

[0082] Beamforming (which may 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 an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming can be achieved by combining signals communicated via antenna elements of an antenna array so that some signals propagating along a particular orientation relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to signals communicated via antenna elements can include the transmitting device or the receiving device applying an amplitude offset, a phase offset, or both to signals carried via antenna elements associated with the device. The adjustments associated with each of these antenna elements can be defined by a set of beamforming weights associated with a particular orientation (e.g., relative to the antenna array of the transmitting device or the receiving device or relative to some other orientation).

[0083] The network entity 105 or the UE 115 may use beam sweeping techniques as part of a beamforming operation. For example, the network entity 105 (e.g., base station 140, RU 170) may use multiple antennas or antenna arrays (e.g., antenna panels) to perform beamforming operations for directional communication with the UE 115. Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted multiple times by the network entity 105 along different directions. For example, the network entity 105 may transmit signals according to different sets of beamforming weights associated with different transmit directions. Transmissions along different beam directions may be used to identify (e.g., by a transmitting device, such as the network entity 105, or by a receiving device, such as the UE 115) the beam direction for later transmission or reception by the network entity 105.

[0084] Some signals, such as data signals associated with a particular receiving device, may be transmitted by a transmitting device (e.g., transmitting network entity 105, transmitting UE 115) along a single beam direction (e.g., a direction associated with a receiving device (e.g., receiving network entity 105 or receiving UE 115)). In some examples, a beam direction associated with transmission along a single beam direction may be determined based on signals transmitted along one or more beam directions. For example, UE 115 may receive one or more of the signals transmitted by network entity 105 along different directions and may report to network entity 105 an indication of the signal received by UE 115 with the highest signal quality or other acceptable signal quality.

[0085] In some examples, transmission by a device (e.g., by network entity 105 or 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 network entity 105 to UE 115). UE 115 may report feedback indicating precoding weights for one or more beam directions, and the feedback may correspond to a configured set of beams across the system bandwidth or one or more subbands. Network entity 105 may transmit reference signals (e.g., cell-specific reference signals (CRS), CSI reference signals (CSI-RS)), which may be precoded or not precoded. 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 codebook, a linear combination codebook, a port selection codebook). Although these techniques are described with reference to signals sent along one or more directions by a network entity 105 (e.g., base station 140, RU 170), UE 115 may use similar techniques to send signals multiple times along different directions (e.g., to identify a beam direction for subsequent transmission or reception by UE 115), or to send signals along a single direction (e.g., to send data to a receiving device).

[0086] A receiving device (e.g., UE 115) may perform reception operations according to multiple reception configurations (e.g., directional listening) when receiving various signals (such as synchronization signals, reference signals, beam selection signals, or other control signals) from a receiving device (e.g., network entity 105). For example, the receiving device may perform reception according to multiple reception directions by receiving via different antenna subarrays, processing received signals according to different antenna subarrays, receiving according to different receive beamforming weight sets applied to signals received at multiple antenna elements of an antenna array (e.g., different directional listening weight sets), or 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 reception configurations or reception directions. In some examples, the receiving device may use a single reception configuration to receive along a single beam direction (e.g., when receiving a data signal). A 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 the highest signal strength, highest signal-to-noise ratio (SNR), or other acceptable signal quality based on listening according to multiple beam directions).

[0087] The wireless communication system 100 may be a packet-based network operating according to a layered protocol stack. In the user plane, communications at the bearer or PDCP layer may be IP-based. The RLC layer may perform packet segmentation and reassembly for communication via logical channels. The MAC layer may perform priority handling and multiplexing of logical channels into transport channels. The MAC layer may also support retransmission using error detection, error correction, or both to improve link efficiency. In the control plane, the RRC layer may provide for the establishment, configuration, and maintenance of RRC connections between the UE 115 and the network entity 105 or core network 130 for radio bearers supporting user plane data. The PHY layer may map transport channels to physical channels.

[0088] The wireless communication system 100 may support various communication procedures. The UE 115 may start in an RRC idle state or an RRC inactive state. The UE 115 may perform initial access with the network entity 105. The initial access may include synchronization signal blocks (SSBs), beam scanning, contention-based random access (CBRA), RACH procedures (e.g., timing, preamble), or any combination thereof. Based on the successful initial access, the UE 115 and the network entity 105 in the RRC connected state may perform beam management procedures. For example, the beam management procedures may support layer 1 (L1) signal-to-interference-plus-noise ratio (SINR) reporting, L1 reference signal received power (RSRP) reporting, overhead and latency reduction (e.g., component carrier aggregation group beam updating, efficient uplink beam updating), latency and efficiency enhancement (e.g., unified transmit configuration indicator (TCI) state, L1 and layer 2 (L2) center mobility, dynamic TCI updating, uplink multi-panel selection, maximum power extrapolation (MPE) mitigation), or any combination thereof.

[0089] In the RRC connected state, the UE 115 may perform beam failure detection based on channel quality measurements or beam measurements. Based on the detection of one or more failed beams, the UE 115 may perform beam failure recovery. For example, the UE 115 may use reference signals, physical downlink control channel (PDCCH) block error rate (BLER), free random access (FRA), link recovery request, MAC-CE, or any combination thereof to perform beam failure detection, beam failure recovery, or both for the primary cell (PCell), primary cell and secondary cell (PSCell), or secondary cell (SCell). In some cases, the UE 115 may perform fast recovery and restart the beam management process. In other cases, the UE 115 may determine that the radio link has failed.

[0090] The wireless communication system 100 can support beam management, beam prediction in the time domain for overhead and latency reduction, beam selection accuracy improvement, or any combination thereof. In some cases, the wireless communication system 100 can utilize artificial intelligence or machine learning techniques. The wireless communication system 100 can perform model training, model deployment, model inference, model monitoring, model updates, or a combination thereof on the AI ​​or ML model to assist in wireless communication methods.

[0091] The wireless communication system 100 can implement inter-cell mobility based on L1 or L2, and the examples described herein can support mobility delay reduction. For example, the wireless communication system 100 can support configuration and maintenance for multiple candidate cells to allow efficient application of the configuration for the candidate cells. In some examples, the wireless communication system 100 can support a dynamic switching mechanism among candidate serving cells (e.g., PCell, SCell, PSCell), which can be based on L1 or L2 signaling. The wireless communication system 100 can support CU-DU interface signaling to support inter-cell mobility based on L1 and / or L2. In some cases, the wireless communication system 100 can support a multi-radio access technology dual connectivity (MR-DC) process, in which selective activation of a cell group is performed via layer 3 enhancement (e.g., to allow CPC, CPAC without reconfiguration and re-initiation of continuous packet connectivity (CPC) or conditional PSCell addition and change (CPAC) after changing the secondary cell group (SCG).

[0092] The wireless communication system 100 can support enhancements in conditional handover, including a target primary cell group (MCG), a target secondary cell group (SCG), or any combination thereof. Conditional handover can include a target MCG and candidate SCG for CPC or CPAC. Conditional handover can include a target MCH and a target SCG used as a baseline. In some examples, the wireless communication system 100 can support the configuration and operation of LTE-like mobile broadband, RACH-free handover procedures, or a combination thereof.

[0093] In some examples, UE 115 may receive control signaling from a first serving cell (e.g., via first network entity 105) indicating a cross-serving cell scheme, the cross-serving cell scheme identifying a first set of resources of a second serving cell (e.g., associated with second network entity 105) associated with a second set of resources of the second serving cell. The first set of resources may be used to measure channel quality for the first set of beams, and the second set of resources may be used to predict channel quality for the second set of beams. UE 115 may perform channel measurement via the first set of resources using the first set of beams according to the cross-serving cell scheme. In some cases, UE 115 may send a CSI report to the first serving cell (e.g., to first network entity 105) based on one or more channel measurements and the cross-serving cell scheme, the CSI report indicating predicted channel quality information for the second set of resources of the second set of beams associated with the second serving cell.

[0094] Figure 2 An example of a wireless communication system 200 that supports predictive beam management across serving cells according to one or more aspects of the present disclosure is illustrated. The wireless communication system 200 may implement aspects of the wireless communication system 100 or may be implemented by it. For example, the wireless communication system 200 may include a UE 115-a and a network entity 105-a, which may be reference Figure 1 Examples of corresponding devices are described.

[0095] In some examples, UE 115-a may be located in serving cell 205-a (e.g., within a geographic coverage area associated with serving cell 205-a). In some examples, network entity 105-a may be located within serving cell 205-a. Network entity 105-a may correspond to each serving cell 205, or each serving cell 205 may correspond to a different network entity 105 (e.g., each of serving cell 205-b, serving cell 205-c, serving cell 205-d, serving cell 205-e, serving cell 205-f, and serving cell 205-g may correspond to a respective network entity 105).

[0096] In some examples, UE 115-a may perform one or more channel quality measurements and may send a CSI report 220 to network entity 105-a that indicates the one or more channel quality measurements. Network entity 105-a may configure UE 115-a (e.g., via CSI report information message 215) with resources on which to perform the one or more channel quality measurements, beams on which to monitor CSI-RS, or a combination thereof. In some examples, as described with reference to FIG. Figure 3Described in more detail, the network entity 105-a may configure the UE 115-a with a first set of resources and a second set of resources. The first set of resources may correspond to a first set of beams (set A), and the network entity 105-a may configure the UE 115-a to use the first set of beams to perform channel measurements via the first set of resources. The second set of resources may be virtual resources, and the network entity 105-a may configure the UE 115-a to use a second set of beams (set B) to perform channel measurement prediction (e.g., indicating predicted channel measurements via CSI report 220) via the second set of resources. The UE 115-a may include the channel measurements for set A and the predicted channel measurements for set B in the CSI report 220.

[0097] In some cases, UE 115-a may be mobile and may be handed off from serving cell 205-a to a different serving cell. For example, UE 115-a may be handed off from serving cell 205-a to serving cell 205-b, and channel measurements or channel measurement predictions performed by the UE in serving cell 205-a may not be applicable to communications within serving cell 205-b, or channel measurements performed with reference to serving cell 205-a may be relevant to another serving cell 205 but not provided to the other serving cell (e.g., thereby resulting in inefficient additional measurements or inefficient reporting).

[0098] Examples described herein may support L1 beam reporting for a non-serving cell in a scenario where a UE 115-a switches from a layer 1 (L1) serving cell to a layer 2 (L2) serving cell. The UE 115-a may support L1 enhancements that include inter-cell beam management, L1 measurements and reporting, beam indication, timing advance (TA) management (e.g., in an unsynchronized scenario), or a combination thereof. In some cases, the UE 115-a or the network entity 105-a may be aware that the UE 115-a may be moving to the serving cell 205-b or may be operating in the serving cell 205-b at a later time. In such cases, it may be beneficial for the UE 115-a to perform measurements and predicted beam measurements for resources within the serving cell 205-b while the UE 115-a is within the serving cell 205-a. For example, UE 115-a may be handed over from serving cell 205-a to serving cell 205-b, and UE 115-a may communicate in serving cell 205-b using predicted beam measurements for resources within serving cell 205-b.

[0099] Thus, UE 115-a can support mobile latency reduction. That is, UE 115-a can reduce the delay or latency associated with switching between serving cell 205-a and serving cell 205-b. For example, UE 115-a can switch (e.g., move) to serving cell 205-b. If the beam on which UE 115-a is currently (e.g., or previously) communicating is no longer valid in serving cell 205-b, initiating a new beam scanning process or performing new CSI measurements and CSI reports may take additional time, resulting in increased latency, faulty communication, or communication gaps (e.g., due to beam direction or interference in serving cell 205-b). In some examples, the beam on which UE 115-a is currently (e.g., or previously) communicating may continue to be valid for cell 205-b. However, re-performing beam selection or CSI measurement and CSI reporting (e.g., when the current or previous beam used by UE 115-a may also be used for communications in serving cell 205-b) may result in unnecessary and inefficient delays. According to the techniques described herein, UE 115-a may utilize channel measurements already performed by UE 115-a for resources corresponding to serving cell 205-b, rather than performing new measurements after switching to serving cell 205-b, which may cause delays in communications with network entity 105-a (e.g., or another network entity 105).

[0100] According to the examples described herein, the network entity 105-a may send a CSI report information message 215 (e.g., via the first serving cell 205-a) that may indicate a first set of resources associated with a second serving cell 205 (e.g., serving cell 205-b) and a second set of resources for the UE 115-a to perform channel quality measurements using a first set of beams corresponding to the first set of resources and to perform channel quality prediction using a second set of beams corresponding to the second set of resources. The CSI report information message 215 may also indicate that the UE 115-a is to report predicted measurements of the second set of resources associated with the serving cell 205-b for the second set of beams. In response to the CSI report information message 215, the UE 115-a may send predicted channel quality measurements for the second set of resources associated with the serving cell 205-b to the network entity 105-a via a CSI report 220 within the serving cell 205-a. The predicted channel quality measurements can support effective and efficient mobility of UE 115-a (e.g., because the UE performs channel quality prediction for cell 205-b and reports it to serving cell 205-a, the UE can more efficiently perform mobility functions when moving from serving cell 205-a to serving cell 205-b based on the channel quality prediction that has been performed and reported).

[0101] In some examples, UE 115-a may send a capability message 210 to network entity 105-a indicating an ability of UE 115-a to support predictive beam management across serving cells. Capability message 210 may indicate that UE 115-a within serving cell 205-a is capable of predicting channel measurements for a different serving cell (e.g., serving cell 205-b). CSI report information message 215 may be based on capability message 210. For example, UE 115-a may indicate the capability of UE 115-a for predictive beam management across serving cells, and network entity 105-a may include resources associated with serving cell 205-b in CSI report information message 215 based on the capability of UE 115-a.

[0102] Figure 3 An example of a channel measurement scheme 300 that supports predictive beam management across serving cells according to one or more aspects of the present disclosure is illustrated. The channel measurement scheme 300 may implement or be implemented by aspects of the wireless communication systems 100 and 200. For example, the channel measurement scheme 300 may include a CSI report 315, which may be as described in reference to FIG. Figure 2 An example of a CSI report 220 is described.

[0103] In some examples of beam management (e.g., AI-based, ML-based beam management), a network entity (e.g., network entity 105-a) may configure a UE with two sets of beams for CSI measurement and prediction. The network entity may configure the UE with a first set of beams 310-a (e.g., set A). The UE may perform measurements on the first set of beams 310-a via a first set of resources 305-a (e.g., channel measurement resources (CMRs)). In some examples, the network entity may configure the UE with a second set of beams 310-b (e.g., set B). The UE may perform beam prediction (e.g., spatial domain downlink beam prediction, temporal downlink beam prediction) for the second set of beams 310-b based on measurement results of the first set of beams 310-a, historical measurement results, or a combination thereof. In some cases, the UE may perform beam prediction using the second set of resources 305-b (e.g., CMRs, virtual resources), and the second set of resources 305-b may correspond to the second set of beams 310-b. The UE may perform measurements using a set of beams 310-a and a set of beams 310-b via resources in the same frequency range or in different frequency ranges (e.g., the first set of resources 305-a and the second set of resources 305-b may partially overlap in frequency, completely overlap in frequency, may correspond to adjacent frequency ranges or bands or sub-bands, or may be completely different from each other).

[0104] In some examples, the first set of beams 310-a may be a subset of the second set of beams 310-b. In some examples, the first set of beams 310-a may have the same number of beams as the second set of beams 310-b, or the set of beams 310 may have a different number of beams. In some cases, the set of beams 310-a may be associated with the set of beams 310-b based on a fixed pattern, a random pattern, or a quasi-co-location relationship. The set of beams 310-a may have different characteristics than the set of beams 310-b. For example, the set of beams 310-a may be wide (e.g., coarse) beams, and the set of beams 310-b may be narrow (e.g., fine) beams. In some examples, the subset of beams 310-b may correspond to a single coarse beam in the set of beams 310-b (e.g., three narrow beams in the set of beams 310-b may correspond to each coarse beam in the set of beams 310-a). The set of beams 310-a may be used for downlink beam measurement, and the set of beams 310-b may be used for DL ​​beam prediction. The set of beams 310 may be indicated by a codebook construction, as shown in FIG. Figure 4A 、 Figure 4B and Figure 5 Described in more detail.

[0105] In some examples, the network entity may configure the UE for a first serving cell (e.g., via RRC configuration). The configuration may include a codebook that may include a set of beams that may be formed by the first serving cell or otherwise associated with the first serving cell (e.g., a first set of beams 310-a, a second set of beams 310-b). The codebook may also include code points, and the network entity may use the code points in a cross-serving cell scheme to identify the first set of beams 310-a, the first set of resources 305-a, the second set of beams 310-b, the second set of resources 305-b, or a combination thereof. The codebook may include a codebook index, where each resource in the set of resources 305 or each beam in the set of beams 310 is indicated by a unique codebook index. In some examples, the network entity may use code points to indicate that: the first set of resources 305-a and the second set of resources 305-b are associated with each other; or the first set of beams 310-a and the second set of beams 310-b are associated with each other; or both.

[0106] The network entity may instruct or request the UE to send a CSI report associated with the first serving cell to the network entity, and the UE may send the CSI report 315 to the network entity. The UE may include in the CSI report 315 measurements of the first set of resources 305-a associated with the first set of beams 310-a, predicted measurements for the second set of resources 305-b associated with the second set of beams 310-b, or a combination thereof. The UE may indicate, via the CSI report (e.g., based on codepoints in an indicated codebook), an association between the measurements of the first set of resources 305-a and the predicted measurements of the second set of resources 305-b. In some examples, the UE may indicate, via the CSI report, a preferred beam, an optimal beam, or a candidate beam from the set of beams 310 by selecting a codepoint index corresponding to the preferred beam, the optimal beam, or the candidate beam in the codebook. In other examples, the UE may indicate a preferred or candidate resource from the set of resources 305 by selecting a codepoint index corresponding to the preferred or candidate resource from the codebook. By using codepoint indexes to select beams or resources in CSI reporting, the UE may support low RRC overhead, or flexibility for dynamically changing beam pointing direction or beam width, or both.

[0107] In some cases, the CSI report, the set of beams 310-a (and the corresponding set of resources 305-a), and the set of beams 310-b (and the corresponding set of resources 305-b) can be associated with a single serving cell. However, the techniques described herein describe signaling and procedures for cross-serving cell configuration of set A and set B beams (e.g., a first set of beams 310-a and a second set of beams 310-b in a second serving cell). The UE may be currently active in the first serving cell. The UE may perform CSI reporting in the currently active serving cell, but may indicate predicted channel quality information for the second serving cell (e.g., for set A and set B beams together with associations with other serving cells configured or indicated in the currently active serving cell through signaling associated with the CSI report).

[0108] In some examples, the network entity may request the UE to send feedback information to the network entity from the first serving cell via one or more CSI reports. The network entity may request the feedback information to include measurement results of a set 305-a of resources (e.g., CMR) and a set 305-b of resources (e.g., CRM or virtual resources) defined in one or more second serving cells different from the first serving cell. The network entity may also request the CSI report to include predicted measurements (e.g., L1-RSRP, L1-SINR) of a set 305-b of resources (e.g., CMR, virtual resources) defined in one or more second serving cells different from the first serving cell. For example, the network entity may send control signaling to the UE indicating a cross-serving cell scheme that identifies a first set 305-a of resources (e.g., of a second serving cell) associated with a second set 305-b of resources. The first set 305-a of resources may be used to measure channel quality for a first set 310-a of beams, and the second set 305-b of resources may be used to predict channel quality for the second set 310-b of beams.

[0109] The UE may perform predicted measurements (e.g., L1-RSRP, L1-SINR) based on an association between the first set of resources 305-a and the second set of resources 305-b. For example, the UE may perform one or more channel measurements via the first set of resources using the first set of beams according to a cross-serving cell scheme. Based on the one or more channel measurements, the UE may send a CSI report 315 to a network entity (e.g., to the first serving cell) indicating predicted channel quality information (e.g., predicted measurements) for the second set of resources 305-b of the second set of beams 310-b associated with the second serving cell.

[0110] The association between the set 305-a of resources and the set 305-b of resources can be configured or indicated separately in the first serving cell, one or more second serving cells, or a combination thereof. For example, control signaling indicating a cross-serving cell scheme can identify the association between the set 305-a of resources and the set 305-b of resources. In some cases, the codebook may indicate beams that can be formed by the second serving cell or otherwise associated with the second serving cell (e.g., a set 310-a of beams for the second cell, a set 310-b of beams). The network entity may configure the UE with a codebook of beams that can be formed by the second serving cell (e.g., via RRC configuration within the configuration information of the second serving cell). The configuration may include a codebook, and the UE may use the beamforming code points within the codebook to identify the association between the first set 310-a of beams and the second set 310-b of beams of the second serving cell.

[0111] Thus, as described herein, a network entity may request (e.g., from a first serving cell) that a UE feed back one or more CSI reports to the network entity. The UE may indicate a predicted channel quality measurement (e.g., predicted L1-RSRP, L1-SINR) regarding a second number or amount of CMRs or virtual resources (e.g., a second set of resources 305-b) defined with reference to one or more second serving cells (e.g., within the second serving cell) based on a measurement result regarding a first number or amount of CMRs (e.g., a first set of resources 305-a) defined with reference to one or more second serving cells (e.g., within the second serving cell). The predicted channel quality measurement may be based on an association between the first number or amount of CMRs and the second number or amount of CMRs or virtual resources, and these associations may be configured or indicated separately in the first serving cell or the second serving cell.

[0112] Figure 4A and Figure 4B Examples of CSI reporting configurations 400 and 435 that support predictive beam management across serving cells according to one or more aspects of the present disclosure are illustrated. The CSI reporting configurations 400 and 435 may implement or be implemented by aspects of the wireless communication systems 100 and 200. For example, the CSI reporting configurations 400 and 435 may include CSI reporting information, such as CSI reporting settings 405-a and CSI reporting settings 405-b, which may be as described in reference to FIG. Figure 2 An example of the described CSI reporting information message 215. In some examples, the CSI reporting setting 405 may be an example of or may indicate a cross-serving cell scheme that identifies a first set of resources of a second serving cell associated with a second set of resources of the second serving cell.

[0113] In some examples, to configure resources of the second serving cell, a serving cell identifier (ID) of the second serving cell (e.g., and an indication of the first amount of resources and the second amount of resources) may be configured and indicated via a CSI report setup message (e.g., CSI report setup 405). The CSI report setup 405 may be provided via periodic, semi-persistent, aperiodic signaling, or any other signaling communicated from the network entity 105-a to the UE 115-a. In some examples, the CSI report setup 405 may be provided via a MAC-CE message that activates semi-persistent CSI reporting or via configuration information (e.g., CSI-AssociatedReportConfigInfo) message with respect to aperiodic CSI reporting.

[0114] exist Figure 4AIn the example, resources may be identified based on a CMR set or a virtual resource set defined in the second serving cell (e.g., resource set 410-a, which may indicate a first amount of resources and a second amount of resources in a first set and a second set of resources, as shown in FIG. Figure 3 described in more detail). For example, the network entity may send a CSI report message (e.g., CSI report setting 405-a) to a UE within a first serving cell. The network entity may trigger CSI reporting by the UE (e.g., by providing the CSI report setting 405-a). The network entity may identify (e.g., in the CSI report setting 405-a) that a resource set 410-a within the CSI report setting 405-a (e.g., a first set of CMRs for CSI measurement and a second set of CMRs for CSI prediction or virtual resources) is defined with reference to a second serving cell that is different from the first serving cell. For example, the CSI report setting 405-a may indicate the resource set 410-a (e.g., including a first set of resources associated with a first set of beams and a second set of resources associated with a second set of beams) using the serving cell ID 415-a. That is, the network entity may indicate that all resources within the resource set 410-a are associated with (e.g., defined with reference to) the second serving cell having the serving cell ID 415-a. The resource set 410-a may include an indication of a first set of resources (e.g., set A) and a second set of resources (e.g., set B) associated with the second serving cell, as shown in FIG. Figure 2 and Figure 3 In some examples, the CSI reporting setup 405-a may include a resource set 410-a (e.g., associated with a serving cell ID 415-a of the second serving cell) and an additional resource set 410 (e.g., associated with a serving cell ID 415-a of the first serving cell). In some examples, the network entity may send the CSI reporting setup 405-a in addition to identifying a separate CSI reporting setup (e.g., a default CSI reporting setup) that includes a resource set associated with the first serving cell.

[0115] The network entity may configure or indicate the serving cell ID 415-a via CSI report setting information 420, which may be an example of CSI report setting 405-a (e.g., the serving cell ID 415-a may be included in the CSI report setting itself) or may be included within the CSI report setting 405-a itself. In some examples, the network entity may configure or indicate the serving cell ID 415-a via a control message 425 (e.g., a MAC-CE) that activates CSI reporting at the UE (e.g., the CSI report setting 405-a may include or may be an example of a MAC-CE that activates CSI reporting (such as semi-persistent CSI reporting)). In some examples, the network entity may configure or indicate the serving cell ID 415-a via configuration information 430 (e.g., CSI-AssociatedReportConfigInfo) that configures CSI reporting at the UE or triggers the UE to send a CSI report (e.g., aperiodically) (e.g., the CSI report setup 405-a may include configuration information 430 identified by the serving cell ID 415-a of the second serving cell or an example of the configuration information).

[0116] exist Figure 4B In some examples, the first set and the second set of resources may be further identified based on a CMR set or a virtual resource set defined in the first serving cell, wherein such resource set also includes a serving cell ID of the second serving cell along with such resources defined in the second serving cell (e.g., individual resources in the resource set in the second serving cell may be identified by the serving cell ID of the second serving cell). In some examples, the network entity may send a CSI reporting setup 405-b to a UE in the first serving cell, which CSI reporting setup may configure CSI reporting for the second serving cell at the UE. The network entity may include a resource set 410-b in the CSI reporting setup 405-b. The resource set 410-b may include resources associated with both the first serving cell and the second serving cell. In some examples, the network entity may indicate the CSI reporting setup 405-b using the serving cell ID of the first serving cell, and each resource in the first set of resources (e.g., the first set of resources 305-a) and the second set of resources of the second serving cell within the resource set 410-b may correspond to a serving cell ID 415-b of the second serving cell. In some examples, resource set 410 - b may also include a first set of resources for a first serving cell and a second set of resources, which may correspond to a serving cell ID of the first serving cell or may not be identified as corresponding to a serving cell-specific ID.

[0117] The network entity may indicate one or more serving cell IDs 415 for individual resources 440 in resource set 410-b. Serving cell ID 415 may indicate which resources in resource set 410-b correspond to a second serving cell. For example, resource 440-a may indicate a first set of resources (e.g., set A, such as second set of resources 305-a) and a second set of resources (e.g., set B, such as second set of resources 305-b) for a second serving cell, and the network entity may indicate, via serving cell ID 415-b, that resource 440-a is associated with the second serving cell (e.g., for each resource 440-a or for the set of resources 440-a). Resource 440-b may be a second set of resources (e.g., including set A and set B) for a second serving cell, and the network entity may indicate, via serving cell ID 415-b, that resource 440-b is associated with the second serving cell.

[0118] In some examples, a network entity may indicate an association between a first set of beams (set A) and a second set of beams (set B) in a second serving cell via a CSI report setting 405. In some cases, the association may be identified based on an RRC configuration at a UE in the second serving cell. The RRC configuration may configure each of the corresponding resources corresponding to the second serving cell, wherein the configuration includes at least one of beam pointing direction or beam width information (e.g., for the first set of beams 310-a and the second set of beams 310-b associated with the first set of resources 305-a and the second set of resources 305-b in each serving cell). For example, the UE may receive a control message from a network entity (e.g., in the second serving cell), the control message including configuration information indicating each resource in the first set of resources and the second set of resources of the second serving cell, a beam direction of each beam in the first set of beams and the second set of beams of the second serving cell, or a combination thereof.

[0119] In some examples, the network entity may configure a serving cell-specific beamforming codebook. The network entity may configure a beamforming codebook for the second serving cell (e.g., via RRC configuration in the second serving cell), the beamforming codebook comprising a set of candidate resources that may be formed by the second serving cell or otherwise associated with the second serving cell, a set of candidate beam pointing directions, a set of candidate beam widths, or any combination thereof. The resource set 410 (e.g., resource set 410-a, resource set 410-b) within the CSI report setting 405 may indicate one or more beamforming code points within the codebook of the second serving cell corresponding to one or more candidate beams or one or more CMRs. Additionally or alternatively, the resources in the resource set 410 may be semi-persistently (SP) activated via MAC-CE (e.g., in the second serving cell), and the MAC-CE may indicate the beamforming code points within the codebook of the second serving cell corresponding to the candidate beams or CMRs. Thus, RRC signaling may indicate a codebook that includes various candidate sets of resources and beams (e.g., different numbers, amounts of resources, or different sets of resources in each of set A and set B, and different beams, beam directions, or beam widths for each of set A and set B), and the network may indicate resource set 410 (e.g., resource set 410-a) via one or more code points of the codebook (e.g., in a CSI report setting).

[0120] In some cases, the association between the first set of beams and the second set of beams of the second serving cell may be jointly configured or indicated in the first serving cell and the second serving cell. The network entity may pre-configure the beamforming codebook for the second serving cell via RRC configuration. In some examples, the network entity may indicate the resource set 410-b within the CSI report setting 405-b. For example, the network entity may indicate one or more beamforming code points within the configured codebook for the first serving cell for resources 440 within the resource set 410-b corresponding to the first serving cell. Additionally, the network entity may indicate one or more beamforming code points within the configured codebook for the second serving cell for resources 440 within the resource set 410-b corresponding to the second serving cell.

[0121] In some examples, a control message (e.g., MAC-CE, control message 425) that activates CSI reporting (e.g., semi-persistent CSI reporting) at the UE or configuration information 430 associated with CSI reporting (e.g., aperiodic CSI reporting) may indicate or configure one or more beamforming code points for each resource associated with the CSI report (e.g., resource 440 within resource set 410-b). One or more code points in the codebook configured at the second serving cell may indicate that resource 440 is associated with the CSI report of the first serving cell or that resource 440 is associated with a corresponding resource in the first serving cell.

[0122] Figure 5 An example of a process flow 500 for supporting predictive beam management across serving cells in accordance with one or more aspects of the present disclosure is illustrated. The process flow 500 may implement or be implemented by aspects of the wireless communication systems 100 and 200. For example, the process flow 500 may include a UE 115-b, a first serving cell 501-a (e.g., serving cell 205-a), a second serving cell 501-b (e.g., serving cell 205, such as serving cell 205-b). Each serving cell 501 may be associated with at least one network entity 105 (e.g., a single network entity 105 may operate via each serving cell 501, or each serving cell 501 may correspond to a respective network entity 105). The UE 115-b, the serving cell 501, and the network entities may be as described in reference to FIG. Figures 1 to 4B Examples of corresponding devices and entities are described. In the following description of process flow 500, operations between UE 115-b and serving cell 501 may be sent in a different order than the example order shown, or operations performed by UE 115-b and serving cell 501 may be performed in a different order or at a different time. Some operations may also be omitted from process flow 500, and other operations may be added to process flow 500.

[0123] At 505, UE 115-b may transmit capability information indicating that UE 115-b supports beam prediction based on a cross-serving cell scheme. In some examples, the capability information may be reported to first serving cell 501-a separately from capability information indicating that UE 115-b supports beam prediction for a single active cell (e.g., first serving cell 501-a). The capability information may include a number of additional (e.g., second) serving cells (e.g., second serving cell 205-b) for which the UE may support beam prediction.

[0124] In some cases, the capability information may include a threshold prediction accuracy for beam prediction for one or more additional serving cells. The threshold prediction accuracy may be specific to each additional serving cell and, in some examples, may be based on the distance from the first serving cell 501-a to the second serving cell 501-b (e.g., the prediction accuracy may vary as the UE 115-b is within a defined distance of the serving cells). In some examples, the capability information may include an amount of reference signal resources, or a type of reference signal resources, or both, which may be used as measurement resources for each of the additional serving cells or may be used as a prediction target for each of the additional serving cells. The UE 115-b may report the capability information to the first serving cell 501-a via RRC configuration during initial access, via dynamic update after initial access, or in both cases. The UE 115-b may expect to be configured by the network entity with a beam prediction request that satisfies its reported capabilities. In some examples, UE 115 - b may report its capability information via RRC signaling during initial access, and optionally also via dynamic updates after initial access.

[0125] At 510, UE 115-b may receive control signaling (e.g., a CSI reporting information message) via first serving cell 501-a (e.g., from a network entity) indicating a cross-serving cell scheme that identifies a first set of resources associated with a second set of resources of second serving cell 501-b. The first set of resources may be used to measure channel quality for a first set of beams (e.g., set A), and the second set of resources may be used to predict channel quality for a second set of beams (e.g., set B). UE 115-b may receive the control signaling based on capability information of UE 115-b (e.g., as indicated at 505).

[0126] UE 115-b may also receive CSI reporting information including an identifier for the second serving cell 501-b (e.g., as referenced in FIG. Figure 4A and Figure 4B The CSI report information may include an indication of the serving cell ID 415 described above. The CSI report information may include an indication of the serving cell ID 415 defined with reference to the identifier of the second serving cell 501-b (e.g., as referenced). Figure 4A An indication of a first set of resources and a second set of resources within the described resource set 410-a. The UE 115-b may receive the CSI reporting information via a CSI report setup message, a MAC-CE activating CSI reporting, a CSI configuration message triggering CSI reporting, or any combination thereof.

[0127] In some cases, UE 115-b may receive CSI reporting information that includes an identifier for the first serving cell 501-a and a plurality of resources including a first set of resources (e.g., of the second serving cell 501-b) and a second set of resources (e.g., as described in reference to FIG. Figure 4B Each resource in the first set of resources and the second set of resources may correspond to an identifier of the second serving cell 501 - b.

[0128] At 515, UE 115-b may receive, via second serving cell 501-b, a control message including configuration information indicating the first set of resources and each resource in the second set of resources, the beam direction of each beam in the first set of beams and the second set of beams, or a combination thereof. UE 115-b may receive, via the configuration information (e.g., via RRC configuration at second serving cell 501-b), an indication of a codebook (e.g., a serving cell-specific codebook) including a set of candidate resources, a set of candidate beam directions, a set of candidate beam widths, or any combination thereof.

[0129] At 520, UE 115-b may perform one or more channel measurements via a first set of resources using a first set of beams in accordance with a cross-serving cell scheme. At 525, UE 115-b may send a CSI report to first serving cell 501-a based on the one or more channel measurements and the cross-serving cell scheme, the CSI report indicating predicted channel quality information for a second set of resources for a second set of beams associated with second serving cell 501-b.

For example, the UE can avoid performing one or more new or redundant channel quality measurements based on a handover to a second serving cell by utilizing channel quality measurements for the second serving cell that were previously performed in a serving cell different from the second serving cell (e.g., the first serving cell).

[0157] Figure 9A diagram illustrating a system 900 including a device 905 that supports predictive beam management across serving cells according to one or more aspects of the present disclosure is shown. The device 905 may be an example of, or include components of, the device 605, device 705, or UE 115 as described herein. The device 905 may communicate (e.g., wirelessly) with one or more network entities 105, one or more UEs 115, or any combination thereof. The device 905 may include components for two-way voice and data communication, including components for sending and receiving communications, such as a communication manager 920, an input / output (I / O) controller 910, a transceiver 915, an antenna 925, a memory 930, code 935, and a processor 940. These components may be in electronic communication or otherwise coupled (e.g., operatively, communicatively, functionally, electronically, electrically) via one or more buses (e.g., bus 945).

[0158] I / O controller 910 can manage input and output signals for device 905. I / O controller 910 can also manage peripheral devices that are not integrated into device 905. In some cases, I / O controller 910 can represent a physical connection or port to an external peripheral device. In some cases, I / O controller 910 can utilize an operating system such as or another known operating system. Additionally or alternatively, I / O controller 910 may represent or interact with a modem, keyboard, mouse, touch screen, or similar device.

However, in some other cases, the device 905 may have more than one antenna 925, which may be capable of concurrently transmitting or receiving multiple wireless transmissions. The transceiver 915 may communicate bidirectionally via one or more antennas 925, wired, or wireless links as described herein. For example, the transceiver 915 may represent a wireless transceiver and may communicate bidirectionally with another wireless transceiver. The transceiver 915 may also include a modem for modulating packets; providing the modulated packets to one or more antennas 925 for transmission; and demodulating packets received from the one or more antennas 925. The transceiver 915, or the transceiver 915 and one or more antennas 925, may be examples of the transmitter 615, transmitter 715, receiver 610, receiver 710, or any combination thereof, or components thereof, as described herein.

[0160] The memory 930 may include random access memory (RAM) and read-only memory (ROM). The memory 930 may store computer-readable, computer-executable code 935 including instructions that, when executed by the processor 940, cause the device 905 to perform the various functions described herein. The code 935 may be stored in a non-transitory computer-readable medium such as system memory or another type of memory. In some cases, the code 935 may not be directly executable by the processor 940, but may (e.g., when compiled and executed) cause the computer to perform the functions described herein. In some cases, the memory 930 may include a basic I / O system (BIOS), etc., which may control basic hardware or software operations such as interaction with peripheral components or devices.

[0161] The processor 940 may include an intelligent hardware device (e.g., a general-purpose processor, a DSP, a CPU, a microcontroller, a GPU, an ASIC, an FPGA, a programmable logic device, a discrete gate or transistor logic component, a discrete hardware component, or any combination thereof).

[0163] By including or configuring the communication manager 920 according to the examples described herein, the device 905 can support techniques for reducing latency by reducing the time duration for the UE to perform channel quality measurements based on a handover from a first serving cell to a second serving cell. For example, the UE can perform fewer channel quality measurements in the second serving cell by leveraging channel quality measurements previously performed in other serving cells, which can reduce latency for the user of the UE, for example, when the UE is mobile.

[0164] In some examples, the communication manager 920 can be configured to use or otherwise cooperate with the transceiver 915, one or more antennas 925, or any combination thereof to perform various operations (e.g., receive, monitor, transmit). Although the communication manager 920 is illustrated as a separate component, in some examples, one or more functions described with reference to the communication manager 920 can be supported or performed by the processor 940, the memory 930, the code 935, or any combination thereof. For example, the code 935 can include instructions that can be executed by the processor 940 to cause the device 905 to perform various aspects of cross-serving cell predictive beam management as described herein, or the processor 940 and the memory 930 can be otherwise configured to perform or support such operations.

Additionally or alternatively, receiver 1010 may support obtaining information by receiving signals via one or more wired (e.g., electrical, optical) interfaces, wireless interfaces, or any combination thereof.

[0167] The transmitter 1015 may provide means for outputting (e.g., transmitting, providing, conveying, transmitting) information generated by other components of the device 1005. For example, the transmitter 1015 may output information associated with various channels (e.g., control channels, data channels, information channels, channels associated with a protocol stack), such as user data, control information, or any combination thereof (e.g., I / Q samples, symbols, packets, protocol data units, service data units).

Memory 1325 may store computer-readable, computer-executable code 1330 including instructions that, when executed by processor 1335, cause device 1305 to perform the various functions described herein. Code 1330 may be stored in a non-transitory computer-readable medium such as system memory or another type of memory. In some cases, code 1330 may not be directly executable by processor 1335, but may (e.g., when compiled and executed) cause a computer to perform the functions described herein. In some cases, memory 1325 may include BIOS, etc., which may control basic hardware or software operations such as interaction with peripheral components or devices.

[0194] The processor 1335 may include an intelligent hardware device (e.g., a general-purpose processor, a DSP, a GPU, an ASIC, a CPU, an FPGA, a microcontroller, a programmable logic device, a discrete gate or transistor logic device, a discrete hardware component, or any combination thereof).

A processing system may generally refer to a system or series of machines or components that receives inputs and processes these inputs to produce a set of outputs (which may be passed to, for example, other systems or components of the device 1305). For example, the processing system of the device 1305 may refer to a system that includes various other components or subcomponents of the device 1305, such as the processor 1335, or the transceiver 1310, or the communication manager 1320, or other components or combinations of components of the device 1305. The processing system of device 1305 can interface with other components of device 1305 and can process information (such as input or signals) received from other components or output information to other components. For example, the chip or modem of device 1305 may include a processing system and one or more interfaces for outputting information or for obtaining information or both. The one or more interfaces may be implemented as or otherwise include a first interface configured to output information and a second interface configured to obtain information or the same interface configured to output information and obtain information, among other specific implementations. In some specific implementations, the one or more interfaces may refer to an interface between the processing system of the chip or modem and a transmitter so that the device 1305 can send information output from the chip or modem.Additionally or alternatively, in some implementations, one or more interfaces may refer to an interface between a processing system of a chip or modem and a receiver, such that the device 1305 can obtain information or signal input and pass the information to the processing system. A person skilled in the art will readily recognize that a first interface may also obtain information or signal input, and a second interface may also output information or signal output.

[0195] In some examples, bus 1340 can support communications for protocol layers in a protocol stack (e.g., within a protocol layer). In some examples, bus 1340 can support communications associated with logical channels of a protocol stack (e.g., between protocol layers in a protocol stack), which can include communications performed within components of device 1305, or communications performed between different components of device 1305 that can be co-located or located in different locations (e.g., where device 1305 can refer to a system in which one or more of communication manager 1320, transceiver 1310, memory 1325, code 1330, and processor 1335 can be located in one of the different components or divided between the different components).

[0196] In some examples, communication manager 1320 can manage aspects of communications with core network 130 (e.g., via one or more wired or wireless backhaul links). For example, communication manager 1320 can manage the delivery of data communications for client devices, such as one or more UEs 115. In some examples, communication manager 1320 can manage communications with other network entities 105 and can include a controller or scheduler for controlling communications with UEs 115 in collaboration with other network entities 105. In some examples, communication manager 1320 can support an X2 interface within LTE / LTE-A wireless communication network technology to provide communications between network entities 105.

[0197] According to examples disclosed herein, the communication manager 1320 may support wireless communications at a network entity. For example, the communication manager 1320 may be configured as or otherwise support means for sending control signaling to a UE via a first serving cell indicating a cross-serving cell scheme, the cross-serving cell scheme identifying a first set of resources of a second serving cell associated with a second set of resources of the second serving cell, the first set of resources being used to measure channel quality for a first set of beams and the second set of resources being used to predict channel quality for a second set of beams. The communication manager 1320 may be configured as or otherwise support means for receiving a CSI report from the UE via the first serving cell based on the cross-serving cell scheme, the CSI report indicating predicted channel quality information for a second set of resources of a second set of beams associated with the second serving cell.

[0198] By including or configuring the communication manager 1320 according to the examples described herein, the device 1305 can support techniques for reducing latency by reducing the time duration for the UE to perform channel quality measurements based on a handover from a first serving cell to a second serving cell. For example, the UE can perform fewer channel quality measurements in the second serving cell by leveraging channel quality measurements previously performed in other serving cells, which can reduce latency for the user of the UE, for example, when the UE is mobile.

[0199] In some examples, the communication manager 1320 can be configured to use or otherwise cooperate with the transceiver 1310, one or more antennas 1315 (e.g., where applicable), or any combination thereof to perform various operations (e.g., receive, obtain, monitor, output, transmit). Although the communication manager 1320 is illustrated as a separate component, in some examples, one or more functions described with reference to the communication manager 1320 can be supported or performed by the transceiver 1310, the processor 1335, the memory 1325, the code 1330, or any combination thereof. For example, the code 1330 can include instructions executable by the processor 1335 to cause the device 1305 to perform various aspects of predictive beam management across serving cells as described herein, or the processor 1335 and the memory 1325 can be otherwise configured to perform or support such operations.
