AI Technical Summary
Current quasi co-location (QCL) TypeD restrictions in wireless communications systems inefficiently use available resources by preventing the reception of downlink signals that overlap with synchronization signal block occasions using the same or different receive beams.
Implementing techniques for quasi co-location multiplexing and prioritization that allow user equipment (UE) to fully utilize simultaneously used beams by selecting a subset of beams based on QCL prioritization rules, which consider combinations of downlink, uplink, and mixed signals for full duplex and sidelink operations.
These techniques enable efficient use of available resources by allowing the UE to prioritize QCL assumptions for allocating multiple beams, thereby improving resource utilization and communication efficiency in wireless communications systems.

[0001] FIELD OF TECHNOLOGY
[0002] The following relates to wireless communications, including techniques for quasi co-location multiplexing and prioritization.BACKGROUND
[0003] Wireless communications systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and so on. These systems may be capable of supporting communication with multiple users by sharing the available system resources (e.g., time, frequency, and power) . Examples of such multiple-access systems include fourth generation (4G) systems such as Long Term Evolution (LTE) systems, LTE-Advanced (LTE-A) systems, or LTE-A Pro systems, and fifth generation (5G) systems which may be referred to as New Radio (NR) systems. These systems may employ technologies such as code division multiple access (CDMA) , time division multiple access (TDMA) , frequency division multiple access (FDMA) , orthogonal FDMA (OFDMA) , or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM) . A wireless multiple-access communications system may include one or more base stations, each supporting wireless communication for communication devices, which may be known as user equipment (UE) .SUMMARY

For example, the described techniques provide for a user equipment (UE) to fully utilize a quantity of simultaneously used beams allowed by UE capability or by operation mode. Additionally, the UE may select a subset of a plurality of beams based on QCL prioritization rules. The QCL prioritization rules may consider any combination of downlink signals, any combination of uplink signals, any combination of mixed downlink signals and uplink signals for full duplex operation, and any combination of transmission signals and receiving signals for sidelink operation.

[0044] In some wireless communications systems, prior to exchanging data and additional messages, a user equipment (UE) may monitor for and receive synchronization signals from a cell or network entity to determine configuration and timing information for transmitting and receiving subsequent messages with the cell or network entity. For example, the cell or network entity may transmit a synchronization signal block (SSB) , and the UE may monitor SSB occasions with one or more receive beams. Current quasi co-location (QCL) TypeD restrictions prevent reception of downlink signals in resources that at least partially overlap with the SSB occasions using a same receive beam for receiving the SSB and the downlink signals. Additionally, current QCL TypeD restrictions prevent reception of the downlink signals in resources that at least partially overlap with the SSB occasions using two different receive beams. The current QCL TypeD restrictions may be an inefficient use of available resources. In some examples, a quantity of simultaneously used beams in a component carrier or across different component carriers may exceed a quantity of beams allowed by UE capacity or operation mode. Thus, a mechanism enabling the UE to efficiently prioritize which QCL assumptions to use for allocating the plurality of beams where communication resources at least partially overlap in time.
[0045] Techniques for QCL multiplexing and prioritization may efficiently use available resources. In some examples, the UE may fully utilize a quantity of simultaneously used beams allowed by UE capability or by operation mode with a single transmission and reception point (sTRP) and multiple transmission and reception points (mTRP) . Additionally, the QCL prioritization rules may consider any combination of downlink signals, any combination of uplink signals, any combination of mixed downlink signals and uplink signals for full duplex operation, and any combination of transmission signals and receiving signals for sidelink operation.
[0046] In some examples, a UE may receive control signaling indicating a set of SSB occasions. The UE may receive control signaling indicating to the UE to monitor a first resource associated with a downlink signal that at least partially overlaps in time with one or more of the set of SSB occasions. The UE may monitor an unmeasured subset of the set of SSB occasions and the resource associated with the downlink signal. A QCL assumption of the unmeasured subset of synchronization signal block occasions may differ from a QCL assumption of the first resource associated with the downlink signal. In some cases, the set of SSB occasions and the downlink signal are configured to be received from a single receive beam on a single component carrier from a sTRP. In some cases, the set of SSB occasions may be configured to be received on a first component carrier and the downlink signal may be configured to be received on a second component carrier.
[0047] In some examples, a UE may receive control signaling configuring a plurality of communication resources for a plurality of beams, and the plurality of communication resources are associated with one or more component carriers. The UE may select a subset of the plurality of beams based on a quantity of the communication resources exceeding a predetermined quantity of beams of the plurality of beams and based on a priority rule for allocating the plurality of beams. The quantity of communication resources may partially overlap in time. The priority rule may be based on a signal type, a transmission configuration indicator type, or a component carrier identifier associated with the one or more component carriers. In some examples, the plurality of communication resources are downlink resources, uplink resources, a combination of downlink resources and uplink resources or sidelink resources.
[0048] Aspects of the disclosure are initially described in the context of wireless communications systems. Aspects of the disclosure are also described in context of a resource diagram, wireless communication systems and process flows. Aspects of the disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flowcharts that relate to techniques for quasi co-location multiplexing and prioritization.
[0049] FIG. 1 shows an example of a wireless communications system 100 that supports techniques for quasi co-location multiplexing and prioritization in accordance with one or more aspects of the present disclosure. The wireless communications 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 communications system 100 may be a Long Term Evolution (LTE) network, an LTE-Advanced (LTE-A) network, an LTE-A Pro network, a New Radio (NR) network, or a network operating in accordance with other systems and radio technologies, including future systems and radio technologies not explicitly mentioned herein.
[0050] The network entities 105 may be dispersed throughout a geographic area to form the wireless communications system 100 and may include devices in different forms or having different capabilities. In various examples, a network entity 105 may be referred to as a network element, a mobility element, a radio access network (RAN) node, or network equipment, among other nomenclature. In some examples, network entities 105 and UEs 115 may wirelessly communicate via one or more communication links 125 (e.g., a radio frequency (RF) access link) . For example, a network entity 105 may support a coverage area 110 (e.g., a geographic coverage area) over which the UEs 115 and the network entity 105 may establish one or more communication links 125. The coverage area 110 may be an example of a geographic area over which a network entity 105 and a UE 115 may support the communication of signals according to one or more radio access technologies (RATs) .
[0051] The UEs 115 may be dispersed throughout a coverage area 110 of the wireless communications system 100, and each UE 115 may be stationary, or mobile, or both at different times. The UEs 115 may be devices in different forms or having different capabilities. Some example UEs 115 are illustrated in FIG. 1. The UEs 115 described herein may be capable of supporting communications with various types of devices, such as other UEs 115 or network entities 105, as shown in FIG. 1.
[0052] As described herein, a node of the wireless communications system 100, which may be referred to as a network node, or a wireless node, may be a network entity 105 (e.g., any network entity described herein) , a UE 115 (e.g., any UE described herein) , a network controller, an apparatus, a device, a computing system, one or more components, or another suitable processing entity configured to perform any of the techniques described herein. For example, a node may be a UE 115. As another example, a node may be a network entity 105. As another example, a first node may be configured to communicate with a second node or a third node. In one aspect of this example, the first node may be a UE 115, the second node may be a network entity 105, and the third node may be a UE 115. In another aspect of this example, the first node may be a UE 115, the second node may be a network entity 105, and the third node may be a network entity 105. In yet other aspects of this example, the first, second, and third nodes may be different relative to these examples. Similarly, reference to a UE 115, network entity 105, apparatus, device, computing system, or the like may include disclosure of the UE 115, network entity 105, apparatus, device, computing system, or the like being a node. For example, disclosure that a UE 115 is configured to receive information from a network entity 105 also discloses that a first node is configured to receive information from a second node.
[0053] In some examples, network entities 105 may communicate with the core network 130, or with one another, or both. For example, network entities 105 may communicate with the core network 130 via one or more backhaul communication links 120 (e.g., in accordance with an S1, N2, N3, or other interface protocol) . In some examples, network entities 105 may communicate with one another via a backhaul communication link 120 (e.g., in accordance with an X2, Xn, or other interface protocol) either directly (e.g., directly between network entities 105) or indirectly (e.g., via a core network 130) . In some examples, network entities 105 may communicate with one another via a midhaul communication link 162 (e.g., in accordance with a midhaul interface protocol) or a fronthaul communication link 168 (e.g., in accordance with a fronthaul interface protocol) , or any combination thereof. The backhaul communication links 120, midhaul communication links 162, or fronthaul communication links 168 may be or include one or more wired links (e.g., an electrical link, an optical fiber link) , one or more wireless links (e.g., a radio link, a wireless optical link) , among other examples or various combinations thereof. A UE 115 may communicate with the core network 130 via a communication link 155.
[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 base transceiver station, a radio base station, an NR base station, an access point, a radio transceiver, a NodeB, an eNodeB (eNB) , a next-generation NodeB or a giga-NodeB (either of which may be referred to as a gNB) , a 5G NB, a next-generation eNB (ng-eNB) , a Home NodeB, a Home eNodeB, or other suitable terminology) . In some examples, a network entity 105 (e.g., a base station 140) may be implemented in an aggregated (e.g., monolithic, standalone) base station architecture, which may be configured to utilize a protocol stack that is physically or logically integrated within a single network entity 105 (e.g., a single RAN node, such as a base station 140) .
[0055] In some examples, a network entity 105 may be implemented in a disaggregated architecture (e.g., a disaggregated base station architecture, a disaggregated RAN architecture) , which may be configured to utilize a protocol stack that is physically or logically distributed among 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, a network entity 105 may include one or more of a central unit (CU) 160, a distributed unit (DU) 165, a radio unit (RU) 170, a RAN Intelligent Controller (RIC) 175 (e.g., a Near-Real Time RIC (Near-RT RIC) , a Non-Real Time RIC (Non-RT RIC) ) , a Service Management and Orchestration (SMO) 180 system, or any combination thereof. An RU 170 may also be referred to as a radio head, a smart radio head, a remote radio head (RRH) , a remote radio unit (RRU) , or a transmission reception point (TRP) . One or more components of the network entities 105 in a disaggregated RAN architecture may be co-located, or one or more components of the network entities 105 may be located in distributed locations (e.g., separate physical locations) . In some examples, one or more network entities 105 of a disaggregated RAN architecture may be implemented as virtual units (e.g., a virtual CU (VCU) , a virtual DU (VDU) , a virtual RU (VRU) ) .
[0056] The split of functionality between a CU 160, a DU 165, and an RU 170 is flexible and may support different functionalities depending on which functions (e.g., network layer functions, protocol layer functions, baseband functions, RF functions, and any combinations thereof) are performed at a CU 160, a DU 165, or an RU 170. For example, a functional split of a protocol stack may be employed between a CU 160 and a DU 165 such that the CU 160 may support one or more layers of the protocol stack and the DU 165 may support one or more different layers of the protocol stack. In some examples, the CU 160 may host upper protocol layer (e.g., layer 3 (L3) , layer 2 (L2) ) functionality and signaling (e.g., Radio Resource Control (RRC) , service data adaption protocol (SDAP) , Packet Data Convergence Protocol (PDCP) ) . The CU 160 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, medium access control (MAC) layer) functionality and signaling, and may each be at least partially controlled by the CU 160. Additionally, or alternatively, a functional split of the protocol stack may be employed between a DU 165 and an RU 170 such that the DU 165 may support one or more layers of the protocol stack and the RU 170 may support one or more different layers of the protocol stack. The DU 165 may support one or multiple different cells (e.g., via one or more RUs 170) . In some cases, a functional split between a CU 160 and a DU 165, or between a DU 165 and an RU 170 may be within a protocol layer (e.g., some functions for a protocol layer may be performed by one of a CU 160, a DU 165, or an RU 170, while other functions of the protocol layer are performed by a different one of the CU 160, the DU 165, or the RU 170) . A CU 160 may be functionally split further into CU control plane (CU-CP) and CU user plane (CU-UP) functions. A CU 160 may be connected to one or more DUs 165 via a midhaul communication link 162 (e.g., F1, F1-c, F1-u) , and a DU 165 may be connected to one or more RUs 170 via a fronthaul communication link 168 (e.g., open fronthaul (FH) interface) . In some examples, a midhaul communication link 162 or a fronthaul communication link 168 may be implemented in accordance with an interface (e.g., a channel) between layers of a protocol stack supported by respective network entities 105 that are in communication via such communication links.
[0057] In wireless communications systems (e.g., wireless communications system 100) , infrastructure and spectral resources for radio access may support wireless backhaul link capabilities to supplement wired backhaul connections, providing an IAB network architecture (e.g., to a core network 130) . In some cases, in an IAB network, one or more 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 an 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) . The one or more donor network entities 105 (e.g., IAB donors) may be in communication 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) . IAB nodes 104 may include an IAB mobile termination (IAB-MT) controlled (e.g., scheduled) by DUs 165 of a coupled IAB donor. An IAB-MT may include an independent set of antennas for relay of communications with UEs 115, or may share the same antennas (e.g., of an RU 170) of an IAB node 104 used for access via the DU 165 of the IAB node 104 (e.g., referred to as virtual IAB-MT (vIAB-MT) ) . In some examples, the IAB nodes 104 may include DUs 165 that support communication links with additional entities (e.g., IAB nodes 104, UEs 115) within the relay chain or configuration of the access network (e.g., downstream) . In such cases, one or more components of the disaggregated RAN architecture (e.g., one or more IAB nodes 104 or components of IAB nodes 104) may be configured to operate according to the techniques described herein.
[0058] In the case of the techniques described herein applied in the context of a disaggregated RAN architecture, one or more components of the disaggregated RAN architecture may be configured to support techniques for quasi co-location multiplexing and prioritization as described herein. For example, some operations described as being performed by a UE 115 or a network entity 105 (e.g., a base station 140) may additionally, or alternatively, be performed by one or more components of the disaggregated RAN architecture (e.g., IAB nodes 104, DUs 165, CUs 160, RUs 170, RIC 175, SMO 180) .
[0059] A UE 115 may include or may be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable terminology, where the “device” may also be referred to as a unit, a station, a terminal, or a client, among other examples. A UE 115 may also include or may be referred to as a personal electronic device such as a cellular phone, a personal digital assistant (PDA) , a tablet computer, a laptop computer, or a personal computer. In some examples, a UE 115 may include or be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communications (MTC) device, among other examples, which may be implemented in various objects such as appliances, or vehicles, meters, among other examples.
[0060] The UEs 115 described herein may be able to communicate with various types of devices, such as other UEs 115 that may sometimes act as relays as well as the network entities 105 and the network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, among other examples, as shown in FIG. 1.
[0061] The UEs 115 and the network entities 105 may wirelessly communicate with one another via one or more communication links 125 (e.g., an access link) using resources associated with one or more carriers. The term “carrier” may refer to a set of RF spectrum resources having a defined physical layer structure for supporting the communication links 125. For example, a carrier used for a communication link 125 may include a portion of a RF spectrum band (e.g., a bandwidth part (BWP) ) that is operated 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 that coordinates operation for the carrier, user data, or other signaling. The wireless communications system 100 may support communication with a UE 115 using carrier aggregation or multi-carrier operation. A UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration. Carrier aggregation may be used with both frequency division duplexing (FDD) and time division duplexing (TDD) component carriers. Communication between a network entity 105 and other devices may refer to communication between the devices and any portion (e.g., entity, sub-entity) of a network entity 105. For example, the terms “transmitting, ” “receiving, ” or “communicating, ” when referring to a network entity 105, may refer to any portion of a network entity 105 (e.g., a base station 140, a CU 160, a DU 165, a RU 170) of a RAN communicating with another device (e.g., directly or via one or more other network entities 105) .
[0062] Signal waveforms transmitted via a carrier may be made up of multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM) ) . In a system employing MCM techniques, a resource element may refer to resources of one symbol period (e.g., a duration of one modulation symbol) and one subcarrier, in which case the symbol period and subcarrier spacing may be inversely related. The quantity of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both) , such that a relatively higher quantity of resource elements (e.g., in a transmission duration) and a relatively higher order of a modulation scheme may correspond to a relatively higher rate of communication. A wireless communications resource may refer to a combination of an RF spectrum resource, a time resource, and a spatial resource (e.g., a spatial layer, a beam) , and the use of multiple spatial resources may increase the data rate or data integrity for communications with a UE 115.
[0063] The time intervals for the network entities 105 or the UEs 115 may be expressed in multiples of a basic time unit which may, for example, refer to a sampling period of Ts=1 / (Δfmax·Nf) seconds, for which Δfmax may represent a supported subcarrier spacing, and Nf may represent a supported discrete Fourier transform (DFT) size. Time intervals of a communications resource may be organized according to radio frames each having a specified duration (e.g., 10 milliseconds (ms) ) . Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023) .
[0064] Each frame may include multiple consecutively-numbered subframes or slots, and each subframe or slot may have the same duration. In some examples, a frame may be divided (e.g., in the time domain) into subframes, and each subframe may be further divided into a quantity of slots. Alternatively, each frame may include a variable quantity of slots, and the quantity of slots may depend on subcarrier spacing. Each slot may include a quantity of symbol periods (e.g., depending on the length of the cyclic prefix prepended to each symbol period) . In some wireless communications systems 100, a slot may further be divided into multiple mini-slots associated with one or more symbols. Excluding the cyclic prefix, each symbol period may be associated with one or more (e.g., Nf) sampling periods. The duration of a symbol period may depend on the subcarrier spacing or frequency band of operation.
[0065] A subframe, a slot, a mini-slot, or a symbol may be the smallest scheduling unit (e.g., in the time domain) of the wireless communications system 100 and may be referred to as a transmission time interval (TTI) . In some examples, the TTI duration (e.g., a quantity of symbol periods in a TTI) may be variable. Additionally, or alternatively, the smallest scheduling unit of the wireless communications system 100 may be dynamically selected (e.g., in bursts of shortened TTIs (sTTIs) ) .
[0066] Physical channels may be multiplexed for communication using a carrier according to various techniques. A physical control channel and a physical data channel may be multiplexed for signaling via a downlink carrier, for example, using one or more of time division multiplexing (TDM) techniques, frequency division multiplexing (FDM) techniques, or hybrid TDM-FDM techniques. A control region (e.g., a control resource set (CORESET) ) for a physical control channel may be defined by a set of symbol periods and may extend across the system bandwidth or a subset of the system bandwidth of the carrier. One or more control regions (e.g., CORESETs) may be configured for a set of the UEs 115. For example, one or more of the UEs 115 may monitor or search control regions for control information according to one or more search space sets, and each search space set may include one or multiple control channel candidates in one or more aggregation levels arranged in a cascaded manner. An aggregation level for a control channel candidate may refer to an amount of control channel resources (e.g., control channel elements (CCEs) ) associated with encoded information for a control information format having a given payload size. Search space sets may include common search space sets configured for sending control information to multiple UEs 115 and UE-specific search space sets for sending control information to a specific UE 115.
[0067] In some examples, a network entity 105 (e.g., a base station 140, an RU 170) may be movable and therefore provide communication coverage for a moving coverage area 110. In some examples, different coverage areas 110 associated with different technologies may overlap, but the different coverage areas 110 may be supported by the same network entity 105. In some other examples, the overlapping coverage areas 110 associated with different technologies may be supported by different network entities 105. The wireless communications system 100 may include, for example, a heterogeneous network in which different types of the network entities 105 provide coverage for various coverage areas 110 using the same or different radio access technologies.
[0068] The wireless communications system 100 may be configured to support ultra-reliable communications or low-latency communications, or various combinations thereof. For example, the wireless communications system 100 may be configured to support ultra-reliable low-latency communications (URLLC) . The UEs 115 may be designed to support ultra-reliable, low-latency, or critical functions. Ultra-reliable communications may include private communication or group communication and may be supported by one or more services such as push-to-talk, video, or data. Support for ultra-reliable, low-latency functions may include prioritization of services, and such services may be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, and ultra-reliable low-latency may be used interchangeably herein.
[0069] In some examples, a UE 115 may be configured to support communicating directly with other UEs 115 via a device-to-device (D2D) communication link 135 (e.g., in accordance with a peer-to-peer (P2P) , D2D, or sidelink protocol) . In some examples, one or more UEs 115 of a group that are performing D2D communications may be within the coverage area 110 of a network entity 105 (e.g., a base station 140, an RU 170) , which may support aspects of such D2D communications being configured by (e.g., scheduled by) the network entity 105. In some examples, one or more UEs 115 of such a group may be outside the coverage area 110 of a network entity 105 or may be otherwise unable to or not configured to receive transmissions from a network entity 105. In some examples, groups of the UEs 115 communicating via D2D communications may support a one-to-many (1: M) system in which each UE 115 transmits to each of the other UEs 115 in the group. In some examples, a network entity 105 may facilitate the scheduling of resources for D2D communications. In some other examples, D2D communications may be carried out between the UEs 115 without an involvement of a network entity 105.
[0070] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 may be an evolved packet core (EPC) or 5G core (5GC) , which may include at least one control plane entity that manages access and mobility (e.g., a mobility management entity (MME) , an access and mobility management function (AMF) ) and at least one user plane entity that routes packets or interconnects to external networks (e.g., a serving gateway (S-GW) , a Packet Data Network (PDN) gateway (P-GW) , or a user plane function (UPF) ) . The control plane entity may manage non-access stratum (NAS) functions such as mobility, authentication, and bearer management for the UEs 115 served by the network entities 105 (e.g., base stations 140) associated with the core network 130. User IP packets may be transferred through the user plane entity, which may provide IP address allocation as well as other functions. The user plane entity may be connected to IP services 150 for one or more network operators. The IP services 150 may include access to the Internet, Intranet (s) , an IP Multimedia Subsystem (IMS) , or a Packet-Switched Streaming Service.
[0071] The wireless communications system 100 may operate using one or more frequency bands, which may be in the range of 300 megahertz (MHz) to 300 gigahertz (GHz) . Generally, the region from 300 MHz to 3 GHz is known as the ultra-high frequency (UHF) region or decimeter band because the wavelengths range from approximately one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features, which may be referred to as clusters, but the waves may penetrate structures sufficiently for a macro cell to provide service to the UEs 115 located indoors. Communications using UHF waves may be associated with smaller antennas and shorter ranges (e.g., less than 100 kilometers) compared to communications using the smaller frequencies and longer waves of the high frequency (HF) or very high frequency (VHF) portion of the spectrum below 300 MHz.
[0072] The wireless communications system 100 may utilize both licensed and unlicensed RF spectrum bands. For example, the wireless communications system 100 may employ License Assisted Access (LAA) , LTE-Unlicensed (LTE-U) radio access technology, or NR technology using an unlicensed band such as the 5 GHz industrial, scientific, and medical (ISM) band. While operating using unlicensed RF spectrum bands, devices such as the network entities 105 and the UEs 115 may employ carrier sensing for collision detection and avoidance. In some examples, operations using unlicensed bands may be based on a carrier aggregation configuration in conjunction with component carriers operating using a licensed band (e.g., LAA) . Operations using unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among other examples.
[0073] A network entity 105 (e.g., a base station 140, an RU 170) or a UE 115 may be equipped with multiple antennas, which may be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. The antennas of a network entity 105 or a UE 115 may be located within one or more antenna arrays or antenna panels, which may support MIMO operations or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly, such as an antenna tower. In some examples, antennas or antenna arrays associated with a network entity 105 may be located at diverse geographic locations. A network entity 105 may include an antenna array with a set of rows and columns of antenna ports that the network entity 105 may use to support beamforming of communications with a UE 115. Likewise, a UE 115 may include one or more antenna arrays that may support various MIMO or beamforming operations. Additionally, or alternatively, an antenna panel may support RF beamforming for a signal transmitted via an antenna port.
[0074] Beamforming, which may also be referred to as spatial filtering, directional transmission, or directional reception, is a signal processing technique that may be used at a transmitting device or a receiving device (e.g., a network entity 105, a UE 115) to shape or steer an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming may be achieved by combining the signals communicated via antenna elements of an antenna array such that some signals propagating along particular orientations with respect to an antenna array experience constructive interference while others experience destructive interference. The adjustment of signals communicated via the antenna elements may include a transmitting device or a receiving device applying amplitude offsets, phase offsets, or both to signals carried via the antenna elements associated with the device. The adjustments associated with each of the antenna elements may be defined by a beamforming weight set associated with a particular orientation (e.g., with respect to the antenna array of the transmitting device or receiving device, or with respect to some other orientation) .
[0075] A network entity 105 or a UE 115 may use beam sweeping techniques as part of beamforming operations. For example, a network entity 105 (e.g., a base station 140, an RU 170) may use multiple antennas or antenna arrays (e.g., antenna panels) to conduct beamforming operations for directional communications with a UE 115. Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted by a network entity 105 multiple times along different directions. For example, the network entity 105 may transmit a signal according to different beamforming weight sets associated with different directions of transmission. Transmissions along different beam directions may be used to identify (e.g., by a transmitting device, such as a network entity 105, or by a receiving device, such as a UE 115) a beam direction for later transmission or reception by the network entity 105.
[0076] Some signals, such as data signals associated with a particular receiving device, may be transmitted by transmitting device (e.g., a transmitting network entity 105, a transmitting UE 115) along a single beam direction (e.g., a direction associated with the receiving device, such as a receiving network entity 105 or a receiving UE 115) . In some examples, the beam direction associated with transmissions along a single beam direction may be determined based on a signal that was transmitted along one or more beam directions. For example, a UE 115 may receive one or more of the signals transmitted by the network entity 105 along different directions and may report to the network entity 105 an indication of the signal that the UE 115 received with a highest signal quality or an otherwise acceptable signal quality.
[0077] In some examples, transmissions by a device (e.g., by a network entity 105 or a UE 115) may be performed using multiple beam directions, and the device may use a combination of digital precoding or beamforming to generate a combined beam for transmission (e.g., from a network entity 105 to a UE 115) . The UE 115 may report feedback that indicates precoding weights for one or more beam directions, and the feedback may correspond to a configured set of beams across a system bandwidth or one or more sub-bands. The network entity 105 may transmit a reference signal (e.g., a cell-specific reference signal (CRS) , a channel state information reference signal (CSI-RS) ) , which may be precoded or unprecoded. The UE 115 may provide feedback for beam selection, which may be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., a multi-panel type codebook, a linear combination type codebook, a port selection type codebook) . Although these techniques are described with reference to signals transmitted along one or more directions by a network entity 105 (e.g., a base station 140, an RU 170) , a UE 115 may employ similar techniques for transmitting signals multiple times along different directions (e.g., for identifying a beam direction for subsequent transmission or reception by the UE 115) or for transmitting a signal along a single direction (e.g., for transmitting data to a receiving device) .
[0078] A receiving device (e.g., a UE 115) may perform reception operations in accordance with multiple receive configurations (e.g., directional listening) when receiving various signals from a transmitting device (e.g., a network entity 105) , such as synchronization signals, reference signals, beam selection signals, or other control signals. For example, a receiving device may perform reception in accordance with multiple receive directions by receiving via different antenna subarrays, by processing received signals according to different antenna subarrays, by receiving according to different receive beamforming weight sets (e.g., different directional listening weight sets) applied to signals received at multiple antenna elements of an antenna array, or by processing received signals according to different receive beamforming weight sets applied to signals received at multiple antenna elements of an antenna array, any of which may be referred to as “listening” according to different receive configurations or receive directions. In some examples, a receiving device may use a single receive configuration to receive along a single beam direction (e.g., when receiving a data signal) . The single receive configuration may be aligned along a beam direction determined based on listening according to different receive configuration directions (e.g., a beam direction determined to have a highest signal strength, highest signal-to-noise ratio (SNR) , or otherwise acceptable signal quality based on listening according to multiple beam directions) .
[0079] In some wireless communications systems, prior to exchanging data and additional messages, the UE 115 may monitor for and receive synchronization signals from a cell or network entity 105 to determine configuration and timing information for transmitting and receiving subsequent messages with the cell or network entity 105. For example, the cell or network entity 105 may transmit a synchronization signal block (SSB) , and the UE 115 may monitor SSB occasions with one or more receive beams. Current quasi co-location (QCL) TypeD restrictions prevent reception of the downlink signals in resources that at least partially overlap with the SSB occasions using a same receive beam for receiving the SSB and the downlink signals. Additionally, current QCL TypeD restrictions prevent reception of the downlink signals in resources that at least partially overlap with the SSB occasions using two different receive beams. The current QCL TypeD restrictions may be an inefficient use of available resources. In some examples, a quantity of simultaneously used beams in a component carrier or across different component carriers may exceed a quantity of beams allowed by UE capacity or operation mode. Thus, a mechanism enabling the UE 115 to efficiently prioritize which QCL assumptions to use for allocating the plurality of beams where communication resources at least partially overlap in time.
[0080] Techniques for QCL multiplexing and prioritization may efficiently use available resources. In some examples, the UE 115 may fully utilize a quantity of simultaneously used beams allowed by UE capability or by operation mode with a single transmission and reception point (sTRP) and multiple transmission and reception points (mTRP) . Additionally, the QCL prioritization rules may consider any combination of downlink signals, any combination of uplink signals, any combination of mixed downlink signals and uplink signals for full duplex operation, and any combination of transmission signals and receiving signals for sidelink operation.
[0081] In some examples, a UE 115 may receive control signaling indicating a set of SSB occasions. The UE 115 may receive control signaling indicating to the UE 115 to monitor a first resource associated with a downlink signal that at least partially overlaps in time with one or more of the set of SSB occasions. The UE 115 may monitor an unmeasured subset of the set of SSB occasions and the resource associated with the downlink signal. A QCL assumption of the unmeasured subset of synchronization signal block occasions may differ from a QCL assumption of the first resource associated with the downlink signal. In some cases, the set of SSB occasions and the downlink signal are configured to be received from a single receive beam on a single component carrier from a single TRP. In some cases, the set of SSB occasions may be configured to be received on a first component carrier and the downlink signal may be configured to be received on a second component carrier.
[0082] In some examples, a UE may receive control signaling configuring a plurality of communication resources for a plurality of beams, and the plurality of communication resources are associated with one or more component carriers. The UE may select a subset of the plurality of beams based on a quantity of the communication resources exceeding a predetermined quantity of beams of the plurality of beams and based on a priority rule for allocating the plurality of beams. The quantity of communication resources may partially overlap in time. The priority rule may be based on a signal type, a transmission configuration indicator type, or a component carrier identifier associated with the one or more component carriers. In some examples, the plurality of communication resources are downlink resources, uplink resources, a combination of downlink resources and uplink resources or sidelink resources.
[0083] FIG. 2 shows an example of a wireless communications system 200 that supports techniques for quasi co-location multiplexing and prioritization in accordance with one or more aspects of the present disclosure. The wireless communications system 200 may implement aspects of or may be implemented by aspects of the wireless communications system 100. For example, the wireless communications system 200 includes a UE 115-a, which may be an example of a UE 115 as described herein. The wireless communications system 200 may also include a network entity 105-a, which may be an example of a network entity 105 as described herein.
[0084] The UE 115-a may communicate with the network entity 105-a using a communication link 125-a. The communication link 125-a may be an example of an NR or LTE link between the UE 115-a and the network entity 105-a. The communication link 125-a may include bi-directional links that enable both uplink and downlink communications. For example, the network entity 105-a may transmit downlink signals (e.g., downlink transmissions) , such as downlink control signaling and downlink data signals, to the UE 115-a using the communication link 125-a, and the UE 115-a may transmit uplink signals (e.g., uplink transmissions) , such as uplink control signaling and uplink data signals, to the network entity 105-a using the communication link 125-a.
[0085] In some wireless communications systems, prior to exchanging data and additional messages, the UE 115-a may monitor for and receive synchronization signals from the network entity 105-a to determine configuration and timing information for transmitting and receiving subsequent messages with the network entity 105-a. For example, the network entity 105-a may transmit a synchronization signal block (SSB) 205, and the UE 115-a may monitor SSB occasions with one or more receive beams. In some examples, the UE 115-a may receive control signaling 210 indicating a set of SSB occasions, and the UE 115-a may receive control signaling 215 indicating to the UE 115-a to monitor a resource associated with a downlink signal 220 that at least partially overlaps in time with one or more of the SSB occasions. Current quasi co-location (QCL) TypeD restrictions prevent reception of the downlink signals in resources that at least partially overlap with the SSB occasions using a same receive beam for receiving the SSB and the downlink signals. Additionally, current QCL-TypeD restrictions prevent reception of the downlink signals in resources that at least partially overlap with the SSB occasions using two different receive beams. The current QCL-TypeD restrictions may be an inefficient use of available resources.
[0086] For example, in the case of a single component carrier and sTRP operation in higher frequency bands (FR2) , the current downlink QCL-TypeD (receiving beam) restriction and prioritization rules do not allow the SSB downlink signal to overlap in time with another SSB downlink signal with the same or different QCL-TypeD properties. In another example, the network entity 105-a may ensure that a channel state information reference signal (CSI-RS) or a signal associated with a physical downlink shared channel (PDSCH) have the same QCL-TypeD properties as the SSB downlink signal overlapping in time. Such QCL-TypeD restrictions may unnecessarily waste resources if the SSB downlink signal has a large overhead in time.
[0087] For example, in the case of a single component carrier and mTRP operation in FR2, the current downlink QCL-TypeD restriction and prioritization rules allow a signal associated with a physical downlink control channel (PDCCH) with different QCLs to be received simultaneously in multiple downlink control information (mDCI) from multiple TRPs or in single downlink control information (sDCI) from multiple TRPs with PDCCH repetition or single frequency network (SFN) . Additionally, the current downlink QCL-TypeD restriction and prioritization rules allow a signal associated with a PDSCH with different QCLs to be received simultaneously on the SSB occasion with one QCL being the same as the QCL of the SSB occasion. However, simultaneous reception in other cases are not specified.
[0088] In some examples, a quantity of simultaneously used beams in a component carrier or across different component carriers may exceed a quantity of beams allowed by UE capacity or operation mode. Thus, a prioritization mechanism may enable the UE to efficiently prioritize which QCL assumptions to use for allocating the plurality of beams where communication resources at least partially overlap in time. For example, in the case of carrier aggregation, the current downlink QCL-TypeD prioritization rules for single TRP operation with search spaces on different component carriers overlapped in time with different QCLs for a signal associated with the control resource set (CORESET) associated with the search spaces may prioritize the QCL of a lowest common search space identifier (CSS ID) with a lowest component carrier identifier (CC ID) if CSS exists. If CSS does not exist, the QCL of lowest UE specific search space identifier (USS ID) may be prioritized. In the case of mDCI multiple TRPs, the prioritization rule may be applied among CORESETs with a same CORESET group index (CORESETPoolIndex) . In the case of sDCI multiple TRPs, the prioritization rule may be applied to a signal associated with the CORESET with SFN or a signal associated with PDCCH repetition. However, there is no QCL prioritization rule for other cases in carrier aggregation, such as a signal associated with PDSCH and a signal associated with PDCCH with different QCLs in different component carriers for the single TRP case.
[0089] In some examples, the UE 115-a may fully utilize the quantity of simultaneous used beams allowed by UE capability or operation mode (e.g., sTRP mode or mTRP mode) . The UE 115-a may be allowed to use a single beam, different from the beam used to receive the SSB, to receive a signal associated with the PDSCH overlapped with SSB, at least when SSB is not measured, to fully utilize the single beam in single TRP mode. Additionally, UE 115-a may be allowed to use two different beams to simultaneously receive CSI-RS and SSB, or CSI-RS and a signal associated with the CORESET, to fully utilized the two simultaneous receiving (Rx) beams in the mTRP mode.
[0090] In some examples, if the quantity of simultaneously used beams in the same component carrier or across different component carriers exceeds a quantity of allowed simultaneously used beams by UE capability or operation mode, the QCL prioritization rule may be extended to any combination of any types of downlink signals, instead of only among signals associated with the PDCCH. Additionally, the QCL prioritization rule may be extended to any combination of uplink signals, any combination of mixed downlink and uplink signals in case of full duplex, and any combination of signals to or from different UEs in case of side link, where the UE 115-a may communicate with different UEs via different beams simultaneously.
[0091] In some examples, to reduce SSB overhead, SSB occasions may be allowed to overlap in time with a resource (s) associated with other downlink signal (s) with QCL-TypeD property different from that of the SSB occasions, at least for not measured SSB occasions. In some cases, the other downlink signals may include a signal associated with the PDSCH, a signal associated with the PDCCH, a CSI-RS or SSB. The other downlink signals may have a same or a different physical cell identity (PCI) as the overlapped SSB. In some examples, the SSB occasions may further satisfy a condition that the SSB occasions are not measured, for example, the SSB may be for layer 1 (L1) , layer 3 (L3) , beam failure detection (BFD) , RLM, or candidate beam measurement. Another condition may be the SSB is from the serving cell of the UE 115-a (e.g., the PCI is not associated with a PCI of a neighbor cell) . In some examples, the UE 115-a may monitor for an unmeasured subset of the set of SSB occasions and, via at least one receive beam, the resource associated with the downlink signal, where a quasi co-location assumption of the unmeasured subset of the set of SSB occasions differs from a quasi co-location assumption of the resource associated with the first downlink signal.
[0092] In some examples, the QCL relaxation rule may be applied to all or a subset of the following three cases. In a first case, the QCL relaxation rule may be applied to a single TRP in a single component carrier, such as only a single beam may be used at a given time. In the first case, the single Rx beam for the other downlink signal may be used on the SSB symbol. In the first case, the set of SSB occasions and the downlink signal may be configured to be received via a single receive beam on a single component carrier from a single TRP. In a second case, the QCL relaxation rule may be applied to multiple TRPs in a single component carrier, such as at least two beams may be used at a given time. In the second case, the multiple Rx beams for the other downlink signals may be used on the SSB symbol and may all be different from the Rx beam used for the SSB. In the second case, the set of SSB occasions and the downlink signal may be configured to be received via at least two receive beams on a single component carrier from multiple transmission and reception points. In a third case, the QCL relaxation rule may be applied to multiple component carriers in aggregation, such as the SSB may be on a first component carrier and the other downlink signals may be on a second component carrier which may be either in sTRP or mTRP operation. In the third case, the set of SSB occasions may be configured to be received on a first component carrier and the first downlink signal may be configured to be received on a second component carrier.
[0093] In some examples, for SSB occasions of a given SSB identifier (ID) , the UE 115-a may reserve a percentage (X%) or a quantity of the SSB occasions for autonomous measurement, which may not be requested by the network entity 105-a or by any protocol (e.g., for UE autonomous Rx beam sweep to identify the best Rx beam for the SSB ID) . In some cases, the network entity 105-a may reserve a percentage or a quantity of the SSB occasions not for any scheduled measurement or not for overlapping with other downlink signal (s) with same or different QCLs, which may result that the overlapped SSB occasion is not measured. The value for the reserved quantity or percentage of SSB occasions may be requested by the UE 115-a, may be determined by the network entity 105-a or may be specified in a specification or standard. The associated SSB ID for the percentage or quantity of reserved SSB occasions may be requested by the UE 115-a, may be determined by the network entity 105-a or may be determined by a rule (e.g., each SSB ID of the top quantity (Y) strongest SSBs reported by the UE 115-a. In some examples, the UE 115-a may monitor a measured subset of the set of SSB occasions, such as the reserved SSB occasions.
[0094] In some examples, in mTRP operation, where the UE 115-a may simultaneously receive with different Rx beams, a combination of downlink signals with different QCLs may be simultaneously received by the UE 115-a, at least when their simultaneous Rx is feasible (e.g., as reported by the UE 115-a in a group-based downlink beam report or the corresponding transmission configuration indications (TCIs) are indicated by network entity 105-a for simultaneous Rx) . For example, the UE 115-a may receive a combination of downlink signals 220. In some cases, the combination of downlink signals may be a CSI-RS and a SSB or a signal associated with a CORESET. In some cases, the combination of downlink signals may be a CSI- RS and another CSI-RS or a signal associated with a PDSCH. In some cases, the combination of downlink signals may a signal associated with the CORESET and a SSB or a signal associated with the PDSCH. In some cases, the combination of downlink signals may be a CSI-RS and another CSI-RS or a signal associated with a PDSCH. In some cases, the combination of downlink signals may be a signal associated with the CORESET and another signal associated with the CORESET. Different QCLs may be not allowed at least for sDCI based multiple TRPs and the two CORESETs may not be linked for PDCCH repetition, and a single CORESET QCL may be prioritized. In some examples, signals associated with CORESETs or CORESET groups may be received simultaneously if the signals follow different TCIs indicated for simultaneous reception (e.g., for frequency duplex multiplexed or space division multiplexed (SDM) PDSCH reception) .
[0095] In some examples, for multiple TRPs where the UE 115-a may simultaneously transmit with different transmission (Tx) beams, a combination of uplink signals with different beams may be simultaneously transmitted by UE 115-a, at least when the simultaneous Tx is feasible (e.g., as reported by UE 115-a in group-based uplink beam report, or the corresponding TCIs are indicated by network entity 105-a for simultaneous Tx) . For example, the UE 115-a may transmit a combination of uplink signals 225. In some cases, the combination of uplink signals may be a sounding reference signal (SRS) and a signal associated with a physical uplink shared channel (PUSCH) . In some cases, the combination of uplink signals may be a SRS and a signal associated with a physical uplink control channel (PUCCH) . In some cases, the combination of uplink signals may be a sounding reference signal (SRS) and a signal associated with a physical uplink random access channel (PRACH) . In some cases, the combination of uplink signals may be a signal associated with a PUSCH and a signal associated with a PUCCH. In some cases, the combination of uplink signals may be a signal associated with a PUSCH and a signal associated with a PRACH. In some cases, the combination of uplink signals may be a signal associated with a PUCCH and a signal associated with a PRACH.
[0096] FIG. 3 shows an example of a resource diagram 300 that supports techniques for quasi co-location multiplexing and prioritization in accordance with one or more aspects of the present disclosure. In some examples, the resource diagram 300 may be implemented by the wireless communications system 200 and the wireless communications system 100. The resource diagram 300 may illustrate a plurality of communication resources for a plurality of beams. The plurality of communication resources at least partially overlap in time. The plurality of communication resources may be associated with one or more component carriers.
[0097] The resource diagram 300 illustrates a first communication resource 305, a second communication resource 310, a third communication resource 315, a fourth communication resource 320, and a fifth communication resource 325. The first communication resource 305 may be associated with a first component carrier 330 and a first beam. The second communication resource 310 may be associated with a second component carrier 335 and a second beam and third beam. The third communication resource 315 may be associated with the second component carrier 335 and a fourth beam. The fourth communication resource may be associated with a third component carrier 340 and a fifth beam. The fifth communication resource may be associated with a fourth component carrier 345 and a sixth beam.
[0098] In some examples, the UE 115-a may receive control signaling 230 configuring a plurality of communication resources for a plurality of beams, where the plurality of communication resources are associated with one or more component carriers. For example, the UE 115-a may be configured with the first communication resource 305, the second communication resource 310, the third communication resource 315, the fourth communication resource 320, and the fifth communication resource 325. The UE 115-a may have a predetermined quantity of beams and the configured communication resources may exceed the available predetermined quantity of beams. For example, the predetermined quantity of beams may be two and the configured communication resources may have six different beams.
[0099] In some examples, the UE 115-a may select a subset of the plurality of beams, such as two beams of the six beams, based on a downlink QCL prioritization rule for allocating the plurality of beams. In case of a maximum X used or activated downlink beams or QCLs across component carriers at a given time, the UE 115-a may implement the downlink beam or QCL prioritization rule if a total used beams or QCL quantity exceeds X across all downlink signals overlapped in time. For example, X may equal two (e.g., maximum two simultaneously used QCLs across the component carriers) . In one example, on a given symbol, the first component carrier 330 and the third component carrier 340 may have downlink signals of CSS with different first beam and fifth beam, which may not follow any unified TCI, the second component carrier 335 may have a signal associated with SDM based semi-persistent scheduling (SPS) with the second beam and third beam following two indicated TCIs, while the second component carrier 335 and the fourth component carrier 345 may have P CSI-RS for beam management (BM) with different fourth beam and sixth beam, which do not follow any unified TCI. The UE 115-a may select two QCLs among the total six different QCLs based on the downlink QCL prioritization rule.
[0100] In some examples, the downlink QCL prioritization may be based on downlink signal type. The downlink signal type and corresponding sub-type (s) may include random access channel (RACH) response signal (e.g., RACH based beam failure recover (BFR) , Msg2 or MsgB PDCCH or PDSCH for contention free random access (CFRA) or contention based random access (CBRA) with or without PDCCH order) . The downlink signal type may include a measurement reference signal (RS) (e.g., SSB or CSI-RS for L3 measurement, such as SSB or CSI-RS for BFR, radio link monitoring (RLS) , candidate beam measurement, SSB or CSI-RS for periodic, semi-persistent, aperiodic (P / SP / AP) L1 reference signal received power (RSRP) or signal interference noise ratio (SINR) or tracking reference signal (TRS) measurement) . The downlink signal type may include a data signal, such as scheduled data with known QCL on overlapped symbol (e.g., distributed generation (DG) PDSCH with scheduling offset greater than timeDurationForQCL, SPS) . The downlink signal type may be a signal associated with a search space (e.g., Type0 / 0A / 1 / 2 CSS, Type3 CSS or USS) . Each downlink signal type (or sub-type) may have an assigned priority. For example, decreasing priority from RACH response signal to measurement RS to data signal to signal associated with a search space. In cases each downlink signal type or sub-type has explicitly indicated physical (PHY) layer priority (e.g., high or low similar to uplink priority in 5G) , the priority list of decreasing priority from RACH response signal to measurement RS to data signal to search space signal may be per PHY layer priority.
[0101] In some examples, based on the downlink signal type or sub-type, the downlink QCL prioritization rule may have the following four steps. For step one, among all time-overlapped downlink signals across component carriers, the UE 115-a may select the downlink signal with highest priority based on the downlink signal type or sub-type, and prioritize the used downlink QCL (s) . If there are multiple downlink signals with the same priority, the UE 115-a may further differentiate the priorities based on the associated CC IDs (e.g., the downlink signal in the lowest CC ID has the highest priority) . In some cases, the downlink signal may have a single or multiple used downlink QCL (s) (e.g., SFN base CORESET with two TCIs, and PDCCH repetition with linked search spaces and two TCIs) . For step two, the UE 115-a may update the remaining allowed QCL quantity as the maximum allowed QCL quantity less the prioritized downlink QCL quantity of step one. For step three, the UE 115-a may exclude other overlapping downlink signals whose QCL (s) are not compatible with the prioritized downlink QCL (s) in step one (e.g., the overlapping downlink signals may not be simultaneously received based on the UE downlink group-based beam report) . For step four, among the remaining time overlapping downlink signals across the component carriers, the UE may select the downlink signal with the highest priority and repeat steps one to four until the remaining allowed QCL quantity is insufficient for the selected downlink signals.
[0102] In some examples, the downlink QCL prioritization across component carriers may be based on a transmission configuration indicator (TCI) type. For example, the QCL indicated by unified TCI may be prioritized over the QCL not indicated by unified TCI. In another example, the QCL not indicated by unified TCI may be prioritized over the QCL indicated by unified TCI.
[0103] In some examples, the downlink QCL prioritization across component carriers may be based on a component carrier identifier (CC ID) . For example, among all component carriers with overlapping downlink signals, the QCL (s) of the downlink signal in the lower CC ID are prioritized first.
[0104] In some examples, the UE 115-a may select a subset of the plurality of beams, such as two beams of the six beams, based on an uplink QCL prioritization rule for allocating the plurality of beams. In case of a maximum Y used or activated uplink beams or QCLs across component carriers at a given time, the UE 115-a may implement the uplink beam or QCL prioritization rule if total used beams or QCL quantity exceeds Y across all uplink signals overlapped in time. For example, Y may equal two (e.g., maximum two simultaneously used QCLs across the component carriers) . In one example, on a given symbol, the first component carrier 330 may have an uplink signal associated with a PRACH with the first beam, which may not follow any unified TCI, the second component carrier 335 may have an uplink signal associated with SDM based configured grant (CG) with the second beam and third beam following two indicated TCIs, while the second component carrier 335 and the fourth component carrier 345 may have P SRS for beam management (BM) with different fourth beam and fifth beam, which do not follow any unified TCI. The UE 115-a may select two QCLs among the total five different QCLs based on the uplink QCL prioritization rule.
[0105] In some examples, the uplink QCL prioritization may be based on uplink signal type. The uplink signal type and corresponding sub-type (s) may include RACH procedure related uplink signals (e.g., Msg1 or MsgA RACH preamble or Msg3 or MsgA PUSCH. The uplink signal type may include measurement RS (e.g., SSB or CSI-RS for L3 measurement, such as SSB or CSI-RS for BFR, radio link monitoring (RLS) , candidate beam measurement, SSB or CSI-RS for P / SP / AP L1 BM / AS / codebook-base (CB) / non-codebook-based (NCB) uplink transmissions) . The uplink signal type may include uplink control information (UCI) (e.g., PUCCH or PUSCH carrying HARQ_ACK information, scheduling request (SR) , CSF, CG-UCI) . The uplink signal type may be a data signal, such as scheduled data (e.g., DG PUSCH or CG) . Each uplink signal type (or sub-type) may have an assigned priority. For example, decreasing priority from RACH procedure uplink signals to measurement RS to UCI to data signals. In cases each uplink signal type or sub-type has explicitly indicated physical (PHY) layer priority (e.g., high or low in 5G) , the priority list of decreasing priority from RACH procedure signal to measurement RS to UCI to data signal may be per PHY layer priority.
[0106] In some examples, based on the uplink signal type or sub-type, the uplink QCL prioritization rule may have the following four steps. For step one, among all time-overlapped uplink signals across component carriers, the UE 115-a may select the uplink signal with highest priority based on its type or sub-type, and prioritize the used uplink QCL (s) . If there are multiple uplink signals with the same priority, the UE 115-a may further differentiate the priorities based on the associated CC IDs (e.g., the uplink signal in the lowest CC ID has the highest priority) . In some cases, the uplink signal may have a single or multiple used uplink QCL (s) (e.g., SDM, FDM, SFN based PUSCH or PUCCH with two TCIs) . For step two, the UE 115-a may update the remaining allowed QCL quantity as the maximum allowed QCL quantity less the prioritized uplink QCL quantity of step one. For step three, the UE 115-a may exclude other overlapping uplink signals whose QCL (s) are not compatible with the prioritized uplink QCL (s) in step one (e.g., the overlapping uplink signals may not be simultaneously transmitted based on the UE uplink group-based beam report) . For step four, among the remaining time overlapping uplink signals across the component carriers, the UE may select the uplink signal with the highest priority and repeat steps one to four until the remaining allowed QCL quantity is insufficient for the selected uplink signals.
[0107] In some examples, the uplink QCL prioritization across component carriers may be based on a transmission configuration indicator (TCI) type. For example, the QCL indicated by unified TCI may be prioritized over the QCL not indicated by unified TCI. In another example, the QCL not indicated by unified TCI may be prioritized over the QCL indicated by unified TCI.
[0108] In some examples, the uplink QCL prioritization across component carriers may be based on component carrier identifier (CC ID) . For example, among all component carriers with overlapping uplink signals, the QCL (s) of the uplink signal in the lower CC ID are prioritized first.
[0109] In some examples, the UE 115-a may select a subset of the plurality of beams, such as two beams of the six beams, based on a joint downlink and uplink QCL prioritization in full duplex rule for allocating the plurality of beams. In full duplex, the UE 115-a may simultaneously transmit and receive with different beams on different component carriers or different subbands per component carrier. In one example, on a given symbol, the UE 115-a may have downlink signals associated with different Rx beams on the first component carrier 330 and the fourth component carrier 345 as well as on a downlink subband of the second component carrier 335. The UE 115-a may also have uplink signals with different Tx beams on the third component carrier 340 as well as on an uplink subband of the second component carrier 335. The uplink signals and the downlink signals may be any uplink signals and any downlink signals discussed herein regarding FIG. 3. The UE 115-a may select two QCLs among the total five different QCLs based on the joint downlink and uplink QCL prioritization in full duplex rule.
[0110] FIG. 4 shows an example of a wireless communications system 400 that supports techniques for quasi co-location multiplexing and prioritization in accordance with one or more aspects of the present disclosure. The wireless communications system 400 may implement aspects of or may be implemented by aspects of the wireless communications systems 100 and 200. For example, the wireless communications system 400 includes a UE 115-b, which may be an example of a UE 115 as described herein. The wireless communications system 400 may also include a network entity 105-b, which may be an example of a network entity 105 as described herein.
[0111] The UE 115-b may communicate with first TRP 405-a and a second TRP 405-b of the network entity 105-b. The UE 115-b may operate in a full duplex mode with simultaneous Tx and Rx with different beams on different component carriers or subbands per component carrier. For example, the first TRP 405-a may transmit a downlink signal with a Tx beam 410, and the UE 115-b may receive the downlink signal with a Rx beam 415. Simultaneously, the UE 115-b may transmit an uplink signal with a Tx beam 420 and the second TRP 405-b may receive the uplink signal with a Rx beam 425. In another example, the first TRP 405-a may transmit a downlink signal with a Tx beam 430, and the UE 115-b may receive the downlink signal with a Rx beam 435. Simultaneously, the UE 115-b may transmit an uplink signal with a Tx beam 440 and the second TRP 405-b may receive the uplink signal with a Rx beam 445. To ensure feasible full duplex communications, the downlink beam (s) and the uplink beam (s) may be selected with low self-interference (SI) from downlink beam (s) to uplink beams (e.g., based on an SI report) . For example, the downlink beam or Rx beam 415 and the uplink beam or Tx beam 420 may be compatible for full duplex communication in terms of SI; and, the downlink beam or Rx beam 435 and the uplink beam or Tx beam 440 may not be compatible for full duplex communication in terms of SI.
[0112] In some examples, the UE 115-b may select a subset of the plurality of beams, such as two beams of the six beams, based on a joint downlink and uplink QCL prioritization in full duplex rule for allocating the plurality of beams. In case of a maximum X and Y used or activated downlink and uplink beams or QCLs across component carriers at a given time, the UE 115-a may implement the joint downlink and uplink beam or QCL prioritization rule if total used downlink and uplink beams or QCL quantity exceeds X or Y across all downlink and uplink signals overlapped in time.
[0113] In some examples, the joint downlink and uplink QCL prioritization may be based on downlink signal type and uplink signal type. The downlink signal type and corresponding sub-type (s) may include random access channel (RACH) response signals (e.g., RACH based beam failure recover (BFR) , Msg2 or MsgB PDCCH or PDSCH for contention free random access (CFRA) or contention based random access (CBRA) with or without PDCCH order) . The downlink signal type may include measurement reference signals (RS) (e.g., SSB or CSI-RS for L3 measurement, such as SSB or CSI-RS for BFR, radio link monitoring (RLS) , candidate beam measurement, SSB or CSI-RS for periodic, semi-persistent, aperiodic (P / SP / AP) L1 reference signal received power (RSRP) or signal interference noise ratio (SINR) or tracking reference signal (TRS) measurement) . The downlink signal type may include data signals (e.g., distributed generation (DG) PDSCH with scheduling offset greater than timeDurationForQCL, SPS) . The downlink signal type may be signals associated with search space (e.g., Type0 / 0A / 1 / 2 CSS, Type3 CSS or USS) . The uplink signal type and corresponding sub-type (s) may include RACH procedure related uplink signals (e.g., Msg1 or MsgA RACH preamble or Msg3 or MsgA PUSCH. The uplink signal type may include measurement RS (e.g., SSB or CSI-RS for L3 measurement, such as SSB or CSI-RS for BFR, radio link monitoring (RLS) , candidate beam measurement, SSB or CSI-RS for P / SP / AP L1 BM / AS / codebook-base (CB) / non-codebook-based (NCB) uplink transmissions) . The uplink signal type may include uplink control information (UCI) (e.g., PUCCH or PUSCH carrying HARQ_ACK information, scheduling request (SR) , CSF, CG-UCI) . The uplink signal type may be data signals (e.g., DG PUSCH or CG. Each downlink signal type (or sub-type) and each uplink signal type (or sub-type) may have an assigned priority. For example, the priorities described herein regarding the downlink QCL prioritization rule and the uplink QCL prioritization rule may be applied to the joint downlink and uplink prioritization rule in full duplex.
[0114] In some examples, based on the downlink signal type or subtype and the uplink signal type or sub-type, the joint downlink and uplink QCL prioritization rule in full duplex may have the following four steps. For step one, among all time-overlapped downlink and uplink signals across component carriers, the UE 115-b may select the downlink signal or the uplink signal with highest priority based on its type or sub-type, and prioritize the used downlink or uplink QCL (s) . If there are multiple downlink and uplink signals with the same priority, the UE 115-a may further differentiate the priorities based on the associated CC IDs (e.g., the signal in the lowest CC ID has the highest priority) . The UE 115-b may select another uplink signal or downlink signal with the highest priority and QCL (s) compatible to the selected downlink or uplink signal together for full duplex operation. For step two, the UE 115-a may update the remaining allowed QCL quantity as the maximum allowed QCL quantity less the prioritized uplink QCL quantity of step one. For step three, the UE 115-a may exclude other overlapping downlink signals and uplink signals whose QCL (s) are not compatible with the prioritized downlink and uplink QCL (s) in step one. Compatible may mean that all selected downlink and uplink QCLs may be simultaneously received and transmitted with negligible cross-beam interference in both a same and reverse directions (e.g., downlink to downlink, uplink to uplink, downlink to uplink, uplink to downlink) . For step four, among the remaining time overlapping downlink signals and uplink signals across the component carriers, the UE 115-b may select the downlink signal or uplink signal with the highest priority and repeat steps one to four until the remaining allow QCL quantity is insufficient for the selected signal.
[0115] FIG. 5 shows an example of a wireless communications system 500 that supports techniques for quasi co-location multiplexing and prioritization in accordance with one or more aspects of the present disclosure. The wireless communications system 500 may implement aspects of or may be implemented by aspects of the wireless communications systems 100, 200 and 400. For example, the wireless communications system 500 includes a sidelink UE 115-c, a first neighbor UE 115-d, a second neighbor UE 115-e, a third neighbor UE 115-f and a fourth neighbor UE 115-g which may be examples of a UE 115 as described herein.
[0116] In some examples, in FR2 sideline communications, the sidelink UE 115-c may simultaneously communicate with multiple neighbor UEs (e.g., the first neighbor UE 115-d, the second neighbor UE 115-e, the third neighbor UE 115-f and the fourth neighbor UE 115-g) in Tx and Rx directions with different beams. For example, the sidelink UE 115-c may receive downlink signals with different Rx beams from the first neighbor UE 115-d and the fourth neighbor UE 115-g, and the sidelink UE 115-c may transmit uplink signals with different Tx beams to the second neighbor UE 115-e and the third neighbor UE 115-f.
[0117] In some examples, if the sidelink UE 115-c operates in half duplex mode, the sidelink UE 115-c may prioritize X compatible Rx beams or Y compatible Tx beams for half duplex operation with selected neighbor UEs, where X and Y are the maximum quantity of downlink and uplink QCLs allowed by UE capability or operation mode. In some examples, the sidelink UE 115-c may prioritize X compatible Rx beams and Y compatible Tx beams for full duplex operation with selected neighbor UEs, where X and Y are the maximum quantity of downlink and uplink QCLs allowed by UE capability or operation mode.
[0118] In some examples, for half duplex sidelink operation, the sidelink UE 115-c may select a subset of the plurality of beams, such as two beams of the six beams, based on a multi-neighbor QCL prioritization in sidelink rule for allocating the plurality of beams. In case of a maximum X or Y used or activated RX or Tx beams or QCLs across neighbor UEs at a given time, the sidelink UE 115-c may implement the multi-neighbor QCL prioritization in sidelink rule to prioritize up to X compatible Rx beams or up to Y compatible Tx beams to communicate with the corresponding neighbor UEs.
[0119] In some examples, the multi-neighbor QCL prioritization in sidelink rule for allocating the plurality of beams in half duplex may have the following four steps. For step one, among all time-overlapped neighbor UEs, the sidelink UE 115-c may select one neighbor UE based on its UE identifier (UE ID) (e.g., lowest or highest MAC or PHY ID for the neighbor UE) . For step two, the sidelink UE 115-c may update the remaining allowed Rx or Tx QCL quantity as the maximum allowed QCL quantity less the prioritized QCL quantity of step one. For step three, the UE 115-a may exclude other time overlapping neighbor UEs not compatible with the Tx or Rx direction of the prioritized neighbor UE in step one. Compatible may mean that either the direction is opposite to the Tx or Rx direction of the prioritized neighbor UE (e.g., Rx direction is opposite the Tx direction) or the QCL may not be simultaneously received or transmitted with the prioritized neighbor UE QCLs. For step four, among the remaining time overlapping neighbor UEs, the sidelink UE 115-c may select the neighbor UE whose Tx or Rx signal has a highest priority and repeat steps one to four until the remaining allowed QCL quantity at the sidelink UE 115-c is insufficient for the selected neighbor UE.
[0120] In some examples, for full duplex sidelink operation, the sidelink UE 115-c may select a subset of the plurality of beams, such as two beams of the six beams, based on a multi-neighbor QCL prioritization in full duplex sidelink rule for allocating the plurality of beams. In case of a maximum X and Y used or activated RX and Tx beams or QCLs across neighbor UEs at a given time, the sidelink UE 115-c may implement the multi-neighbor QCL prioritization in full duplex sidelink rule to prioritize up to X compatible Rx beams and up to Y compatible Tx beams to communicate with the corresponding neighbor. UEs.
[0121] In some examples, based on the Rx signal type or subtype and the Tx signal type or sub-type, the multi-neighbor QCL prioritization rule in sidelink full duplex may have the following four steps. For step one, among all time-overlapped neighbor UEs, the sidelink UE 115-c may select the neighbor UE whose Tx or Rx signal has a highest priority based on the signal type or sub-type, and prioritize the used Rx or Tx QCL (s) . If there are multiple neighbor UEs with the same priority, the sidelink UE 115-c may further differentiate the priorities based on the associated UE IDs. The UE 115-b may select another neighbor UE with the highest priority and QCL (s) compatible to the selected Rx or Tx of the selected neighbor UE together for full duplex operation. For step two, the sidelink UE 115-c may update the remaining allowed QCL quantity as the maximum allowed QCL quantity less the prioritized uplink QCL quantity of step one. For step three, the UE 115-a may exclude other overlapping neighbor UEs whose QCL (s) are not compatible with the prioritized neighbor UE. For step four, among the remaining time overlapping neighbor UEs, the sidelink UE 115-c may select the neighbor UE whose Rx or Tx signal has the highest priority and repeat steps one to four until the remaining allow QCL quantity is insufficient for the selected neighbor UE.

A general-purpose processor may be a microprocessor but, in the alternative, the processor may be any processor, controller, microcontroller, or state machine. A processor may also be implemented as a combination of computing devices (e.g., a combination of a DSP and a microprocessor, multiple microprocessors, one or more microprocessors in conjunction with a DSP core, or any other such configuration) . Any functions or operations described herein as being capable of being performed by a processor may be performed by multiple processors that, individually or collectively, are capable of performing the described functions or operations.
[0236] The functions described herein may be implemented using hardware, software executed by a processor, firmware, or any combination thereof. If implemented using software executed by a processor, the functions may be stored as or transmitted using one or more instructions or code of a computer-readable medium. Other examples and implementations are within the scope of the disclosure and appended claims. For example, due to the nature of software, functions described herein may be implemented using software executed by a processor, hardware, firmware, hardwiring, or combinations of any of these. Features implementing functions may also be physically located at various positions, including being distributed such that portions of functions are implemented at different physical locations.
[0237] Computer-readable media includes both non-transitory computer storage media and communication media including any medium that facilitates transfer of a computer program from one location to another. A non-transitory storage medium may be any available medium that may be accessed by a general-purpose or special-purpose computer. By way of example, and not limitation, non-transitory computer-readable media may include RAM, ROM, electrically erasable programmable ROM (EEPROM) , flash memory, compact disk (CD) ROM or other optical disk storage, magnetic disk storage or other magnetic storage devices, or any other non-transitory medium that may be used to carry or store desired program code means in the form of instructions or data structures and that may be accessed by a general-purpose or special-purpose computer, or a general-purpose or special-purpose processor. Also, any connection is properly termed a computer-readable medium. For example, if the software is transmitted from a website, server, or other remote source using a coaxial cable, fiber optic cable, twisted pair, digital subscriber line (DSL) , or wireless technologies such as infrared, radio, and microwave, then the coaxial cable, fiber optic cable, twisted pair, DSL, or wireless technologies such as infrared, radio, and microwave are included in the definition of computer-readable medium. Disk and disc, as used herein, include CD, laser disc, optical disc, digital versatile disc (DVD) , floppy disk and Blu-ray disc.

[0238] As used herein, including in the claims, “or” as used in a list of items (e.g., a list of items prefaced by a phrase such as “at least one of” or “one or more of” ) indicates an inclusive list such that, for example, a list of at least one of A, B, or C means A or B or C or AB or AC or BC or ABC (i.e., A and B and C) . Also, as used herein, the phrase “based on” shall not be construed as a reference to a closed set of conditions. For example, an example step that is described as “based on condition A” may be based on both a condition A and a condition B without departing from the scope of the present disclosure. In other words, as used herein, the phrase “based on” shall be construed in the same manner as the phrase “based at least in part on. ”
[0239] As used herein, including in the claims, the article “a” before a noun is open-ended and understood to refer to “at least one” of those nouns or “one or more” of those nouns. Thus, the terms “a, ” “at least one, ” “one or more, ” “at least one of one or more” may be interchangeable. For example, if a claim recites “a component” that performs one or more functions, each of the individual functions may be performed by a single component or by any combination of multiple components. Thus, the term “acomponent” having characteristics or performing functions may refer to “at least one of one or more components” having a particular characteristic or performing a particular function. Subsequent reference to a component introduced with the article “a” using the terms “the” or “said” may refer to any or all of the one or more components. For example, a component introduced with the article “a” may be understood to mean “one or more components, ” and referring to “the component” subsequently in the claims may be understood to be equivalent to referring to “at least one of the one or more components. ” Similarly, subsequent reference to a component introduced as “one or more components” using the terms “the” or “said” may refer to any or all of the one or more components. For example, referring to “the one or more components” subsequently in the claims may be understood to be equivalent to referring to “at least one of the one or more components. ”
[0240] The term “determine” or “determining” encompasses a variety of actions and, therefore, “determining” can include calculating, computing, processing, deriving, investigating, looking up (such as via looking up in a table, a database or another data structure) , ascertaining and the like. Also, “determining” can include receiving (e.g., receiving information) , accessing (e.g., accessing data stored in memory) and the like. Also, “determining” can include resolving, obtaining, selecting, choosing, establishing, and other such similar actions.
[0241] In the appended figures, similar components or features may have the same reference label. Further, various components of the same type may be distinguished by following the reference label by a dash and a second label that distinguishes among the similar components. If just the first reference label is used in the specification, the description is applicable to any one of the similar components having the same first reference label irrespective of the second reference label, or other subsequent reference label.
[0242] The description set forth herein, in connection with the appended drawings, describes example configurations and does not represent all the examples that may be implemented or that are within the scope of the claims. The term “example” used herein means “serving as an example, instance, or illustration, ” and not “preferred” or “advantageous over other examples. ” The detailed description includes specific details for the purpose of providing an understanding of the described techniques. These techniques, however, may be practiced without these specific details. In some instances, known structures and devices are shown in block diagram form in order to avoid obscuring the concepts of the described examples.
[0243] The description herein is provided to enable a person having ordinary skill in the art to make or use the disclosure. Various modifications to the disclosure will be apparent to a person having ordinary skill in the art, and the generic principles defined herein may be applied to other variations without departing from the scope of the disclosure. Thus, the disclosure is not limited to the examples and designs described herein but is to be accorded the broadest scope consistent with the principles and novel features disclosed herein.
