Abstract

Methods, systems, and devices for wireless communications are described. A wireless communications system may support quasi co-location prioritization techniques. A user equipment (UE) may receive control signaling to monitor at least one control resource set. The UE may receive a control message to monitor a shared data channel that overlaps in time with the at least one control resource set. For example, the control message may schedule a downlink message via the shared data channel in a time period of the at least one control resource set. The UE may monitor the at least one control resource set, the shared data channel, or both based on one or more priority rules. A priority rule may indicate to monitor a corresponding control resource set, shared data channel, or both based on whether the quasi co-location assumptions of the various control resource sets or shared data channels are the same or different.

FIELD OF TECHNOLOGY

[0002] The following relates to wireless communications, including quasi co- location prioritization for wireless communications systems.

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 network entities or one or more network access nodes, each simultaneously supporting communication for multiple communication devices, which may be otherwise known as user equipment (UE). In some wireless communications systems, downlink control 2 messages (e.g., downlink control information (DCI) messages) may schedule other downlink messages from a network entity to a UE. However, in some cases the UE may be unable to efficiently receive the one or more downlink control messages or other downlink messages.

SUMMARY

[0004] The described techniques relate to improved methods, systems, devices, and apparatuses that support quasi co-location (QCL) prioritization for wireless communications systems. Generally, the described techniques enable devices in a wireless communications system to implement one or more priority rules for allocating receive beams for various communications. For example, a user equipment (UE) may receive control signaling indicating to monitor one or more control resource sets (CORESETs). The UE may receive a control message scheduling a downlink message (e.g., a shared data channel message). In some examples, the downlink message may overlap in time with the one or more control resource sets. The UE may monitor the downlink message (e.g., the shared data channel), the one or more CORESETs, or a combination thereof in accordance with a priority rule. The priority rule may indicate which QCL properties to use for monitoring the control resource sets, the downlink message, or both. By implementing such priority rules, the UE may efficiently allocate receive beams to receive the communications, which may result in improved communications efficiency, reliability, or both.

The method may include receiving control signaling indicating to the UE to monitor at least one CORESET, receiving a control message indicating to the UE to monitor a shared data channel that overlaps in time with the at least one CORESET, and monitoring, via a set of multiple receive beams, the at least one CORESET, the shared data channel, or both, based on a priority rule for allocating the set of multiple receive beams of the UE for monitoring of the at least one CORESET, the shared data channel, or both.

DETAILED DESCRIPTION

[0062] In some wireless communications systems, downlink control messages (e.g., DCI messages) may schedule communication of other downlink messages (e.g., physical downlink shared channel (PDSCH) messages) from a network entity to a UE. The UE may be configured to determine what QCL assumption (e.g., QCL parameters 16 or QCL type properties, beam parameters, transmission configuration indicator (TCI) state, and the like) is to be used for receiving the scheduled downlink PDSCH message based on the downlink control message. For example, the QCL assumption used for receiving the downlink control message may also be used for the scheduled downlink PDSCH message or another QCL assumption may be used.

[0063] In some cases, the UE may monitor one or more control resource sets (CORESETs) for multiple linked control channel candidates (e.g., physical downlink control channel (PDCCH) candidates). That is, the control channel candidates may be linked for multiple repetitions of the same downlink control message. For example, a same downlink control information (DCI) payload may be transmitted via two (or more) PDCCH candidates in a slot (e.g., the PDCCH candidates may overlap in time). In some examples, each of the control channel candidates may be associated with one or more QCL assumptions. Additionally or alternatively, the scheduled PDSCH may be associated with one or more QCL assumptions. However, some wireless communications systems may not provide a UE with a mechanism for determining which QCL assumptions should be used for monitoring or receiving one or more CORESETs, a shared data channel, or both.

[0064] Accordingly, the techniques described herein may enable devices in a wireless communications system to implement one or more priority rules for allocating receive beams for various communications. For example, a UE may receive control signaling indicating that the UE is to monitor one or more CORESETs. Additionally, the UE may receive a control message scheduling a downlink message (e.g., a PDSCH message). In some examples, the downlink message may overlap in time with the one or more control resource sets. The UE may monitor the downlink message (e.g., the shared data channel), the one or more CORESETs, or a combination thereof in accordance with a priority rule. The priority rule may indicate which QCL assumptions for the UE to use for monitoring the control resource sets, the downlink message, or both. For the purposes of the present disclosure, the terms “TCI state” and “QCL assumption” may be used to refer to a beam (or set of beams) which are used to transmit/receive a message between wireless devices. Accordingly, the terms “beam,” “TCI state,” “QCL assumption,” “QCL parameters,” “QCL properties,” and the like may be used interchangeably. 17

[0065] In some examples, the downlink message may correspond to one or more TCI states. The priority rule may indicate which QCL assumptions the UE should use to monitor the one or more CORESETs in addition or alternative to the downlink message. As an illustrative example, the UE may be capable of reception via two beams (e.g., the UE may implement up to two QCL assumptions for monitoring or receiving communications). The UE may be indicated to monitor one or more CORESETs associated with one or more QCL assumptions (e.g., a single CORESET associated with one or more QCL assumptions, two CORESETs each associated with a respective QCL assumption, and so on). Further, the UE may be indicated to monitor the downlink message associated with a TCI. In other words, the UE may be capable of reception using up to two QCL assumptions but may be indicated to monitor the CORESETs and downlink message using one, two, three, or four QCL assumptions in a same time period (e.g., in a slot). Thus, the UE may identify the QCL assumptions for monitoring (or refraining from monitoring) the CORESETs and downlink message based on the one or more priority rules indicating the QCL assumptions for a respective scenario. For example, a priority rule may indicate the QCL assumptions to use when the downlink message corresponds to one or more different QCL assumptions as the one or more CORESETs, when the downlink message corresponds to one or more of the same QCL assumptions as the one or more CORESETs, or any combination thereof, among other examples described herein. By implementing such priority rules, the UE may efficiently allocate receive beams to receive the various communications (e.g., CORESETs, downlink messages, or both), which may result in improved communications efficiency, reliability, or both.

[0066] Aspects of the disclosure are initially described in the context of wireless communications systems. Some example techniques may relate to PDCCH and PDSCH QCL-TypeD prioritization in the presence of PDCCH repetition. Additional aspects of the disclosure are described in the context of an example resource configuration, example priority schemes, and an example process flow. Aspects of the disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flowcharts that relate to quasi co-location prioritization for wireless communications systems. 18

[0067] FIG. 1 illustrates an example of a wireless communications system 100 that supports quasi co-location prioritization for wireless communications systems in accordance with 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. In some examples, the wireless communications system 100 may support enhanced broadband communications, ultra-reliable (e.g., mission critical) communications, low latency communications, communications with low-cost and low-complexity devices, or any combination thereof.

[0068] The network entities 105 may be dispersed throughout a geographic area to form the wireless communications system 100 and may be devices in different forms or having different capabilities. In various examples, a network entity 105 may be referred to as a network element, a base station, a mobility element, a radio access network (RAN) node, or network equipment, among other nomenclature. In some examples, network entities 105 and the 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).

[0069] 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 able to communicate with various types of devices, such as other UEs 115 or the network entities 105 as shown in FIG. 1.

[0070] 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 19 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.

[0071] 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 SI, N2, N3, or other interface protocol). In some examples, network entities 105 may communicate with one another over 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 through a communication link 155. 20

[0072] 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).

[0073] 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 (LAB) 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)).

[0074] The split of functionality between a CU 160, a DU 165, and an RU 170 is flexible and may support different functionalities depending upon 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 21 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 DUs 165 or RUs 170, and the DUs 165 or RUs 170 may host lower protocol layers, such as layer 1 (LI) (e.g., physical (PHY) layer) or L2 (e.g., radio link control (RLC) layer, medium access control (MAC) layer) functionality and signaling, and 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 DUs 165 via a midhaul communication link 162 (e.g., FI, Fl-c, Fl-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 over such communication links.

[0075] 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 LAB 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 22 each other. One or more IAB nodes 104 may be referred to as a donor entity or an IAB donor. The DUs 165 or one or more RUs 170 may be partially controlled by 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.

[0076] 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 phase tracking reference signals and demodulation reference signals for joint channel estimation 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).

[0077] 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 23 machine type communications (MTC) device, among other examples, which may be implemented in various objects such as appliances, or vehicles, meters, among other examples.

[0078] 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 network entities, among other examples, as shown in FIG. 1.

[0079] The UEs 115 and the network entities 105 may wirelessly communicate with one another via one or more communication links 125 over one or more carriers. The term “carrier” may refer to a set of radio frequency 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 radio frequency 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).

[0080] Signal waveforms transmitted over a carrier may be made up of multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques such as orthogonal 24 frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)). In a system employing MCM techniques, a resource element may consist of one symbol period (e.g., a duration of one modulation symbol) and one subcarrier, where the symbol period and subcarrier spacing are inversely related. The number of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both). Thus, the more resource elements that a UE 115 receives and the higher the order of the modulation scheme, the higher the data rate may be for the UE 115. A wireless communications resource may refer to a combination of a radio frequency spectrum resource, a time resource, and a spatial resource (e.g., spatial layers or beams), and the use of multiple spatial layers may further increase the data rate or data integrity for communications with a UE 115.

[0081] 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 T_s = l/(A/_ma iV_·) seconds, where A/_ma may represent the maximum supported subcarrier spacing, and JV- may represent the maximum 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).

[0082] 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 number of slots. Alternatively, each frame may include a variable number of slots, and the number of slots may depend on subcarrier spacing. Each slot may include a number 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 containing one or more symbols. Excluding the cyclic prefix, each symbol period may contain 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. 25

[0083] 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., the number 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)).

[0084] Physical channels may be multiplexed on a carrier according to various techniques. A physical control channel and a physical data channel may be multiplexed on 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 number 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 a number 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.

[0085] In some examples, a network entity 105 may be movable and therefore provide communication coverage for a moving geographic coverage area 110. In some examples, different geographic coverage areas 110 associated with different technologies may overlap, but the different geographic coverage areas 110 may be supported by the same network entity 105. In other examples, the overlapping geographic 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 26 entities 105 provide coverage for various geographic coverage areas 110 using the same or different radio access technologies.

[0086] 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) or mission critical communications. The UEs 115 may be designed to support ultra-reliable, low-latency, or critical functions (e.g., mission critical functions). Ultra-reliable communications may include private communication or group communication and may be supported by one or more mission critical services such as mission critical push-to-talk (MCPTT), mission critical video (MCVideo), or mission critical data (MCData). Support for mission critical functions may include prioritization of services, and mission critical services may be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, mission critical, and ultra-reliable low-latency may be used interchangeably herein.

[0087] In some examples, a UE 115 may also be able to communicate directly with other UEs 115 over a device-to-device (D2D) communication link 135 (e.g., using a peer-to-peer (P2P) or D2D protocol). One or more UEs 115 utilizing D2D communications may be within the geographic coverage area 110 of a network entity 105. Other UEs 115 in such a group may be outside the geographic coverage area 110 of a network entity 105 or be otherwise unable to receive transmissions from a network entity 105. In some examples, groups of the UEs 115 communicating via D2D communications may utilize a one-to-many (1:M) system in which each UE 115 transmits to every other UE 115 in the group. In some examples, a network entity 105 facilitates the scheduling of resources for D2D communications. In other cases, D2D communications are carried out between the UEs 115 without the involvement of a network entity 105.

[0088] 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 27 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 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.

[0089] Some of the network devices, such as a network entity 105, may include subcomponents such as an access network entity 140, which may be an example of an access node controller (ANC). Each access network entity 140 may communicate with the UEs 115 through one or more other access network transmission entities 145, which may be referred to as radio heads, smart radio heads, or transmission/reception points (TRPs). Each access network transmission entity 145 may include one or more antenna panels. In some configurations, various functions of each access network entity 140 or network entity 105 may be distributed across various network devices (e.g., radio heads and ANCs) or consolidated into a single network device (e.g., a network entity 105).

[0090] The wireless communications system 100 may operate using one or more frequency bands, typically 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. The UHF waves may be blocked or redirected by buildings and environmental features, but the waves may penetrate structures sufficiently for a macro cell to provide service to the UEs 115 located indoors. The transmission of UHF waves may be associated with smaller antennas and shorter ranges (e.g., less than 100 kilometers) compared to transmission using the smaller frequencies and longer waves of the high frequency (HF) or very high frequency (VHF) portion of the spectrum below 300 MHz.

[0091] The wireless communications system 100 may utilize both licensed and unlicensed radio frequency spectrum bands. For example, the wireless communications 28 system 100 may employ License Assisted Access (LAA), LTE-Unlicensed (LTE-U) radio access technology, or NR technology in an unlicensed band such as the 5 GHz industrial, scientific, and medical (ISM) band. When operating in unlicensed radio frequency 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 in unlicensed bands may be based on a carrier aggregation configuration in conjunction with component carriers operating in a licensed band (e.g., LAA). Operations in unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among other examples.

[0092] A network entity 105 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 network entity 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 in diverse geographic locations. A network entity 105 may have an antenna array with a number 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 have one or more antenna arrays that may support various MIMO or beamforming operations. Additionally or alternatively, an antenna panel may support radio frequency beamforming for a signal transmitted via an antenna port.

[0093] The network entities 105 or the UEs 115 may use MIMO communications to exploit multipath signal propagation and increase the spectral efficiency by transmitting or receiving multiple signals via different spatial layers. Such techniques may be referred to as spatial multiplexing. The multiple signals may, for example, be transmitted by the transmitting device via different antennas or different combinations of antennas. Likewise, the multiple signals may be received by the 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 bits associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different 29 codewords). Different spatial layers may be associated with different antenna ports used for channel measurement and reporting. MIMO techniques include single-user MIMO (SU-MIMO), where multiple spatial layers are transmitted to the same receiving device, and multiple-user MIMO (MU-MIMO), where multiple spatial layers are transmitted to multiple devices.

[0094] 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 at 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).

[0095] A network entity 105 or a UE 115 may use beam sweeping techniques as part of beam forming operations. For example, a network entity 105 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 in 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 in 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. 30

[0096] Some signals, such as data signals associated with a particular receiving device, may be transmitted by a network entity 105 in a single beam direction (e.g., a direction associated with the receiving device, such as a 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 in one or more beam directions. For example, a UE 115 may receive one or more of the signals transmitted by the network entity 105 in 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.

[0097] 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 radio frequency 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 number 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 in one or more directions by a network entity 105, a UE 115 may employ similar techniques for transmitting signals multiple times in different directions (e.g., for identifying a beam direction for subsequent transmission or reception by the UE 115) or for transmitting a signal in a single direction (e.g., for transmitting data to a receiving device).

[0098] A receiving device (e.g., a UE 115) may try multiple receive configurations (e.g., directional listening) when receiving various signals from the network entity 105, such as synchronization signals, reference signals, beam selection signals, or other control signals. For example, a receiving device may try 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 31 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 in 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).

[0099] In some aspects, a UE 115 of the wireless communications system 100 may be configured (e.g., via radio resource control (RRC) signaling) with up to three CORESETS within a given BWP of a serving cell (e.g., within a given BWP of a component carrier). In some cases (e.g., Release 16), a UE 115 may be configured with up to five CORESETs in a BWP of a serving cell. A CORESET may be associated with one or more transmission configuration indicator (TCI) states for PDCCH repetition, and may be associated with a quantity of resource blocks (RBs) in the frequency domain, and a quantity of symbols or other TTI in the time domain (e.g., quantity of 1/2/3 OFDM symbols), each of which may be configured (e.g., via RRC signaling). Moreover, each CORESET may be associated with one active TCI state. In some aspects, a CORESET configured at the UE 115 may be associated with a control channel element (CCE) resource element group (CCE-REG) mapping type (e.g., CCE- REG bundle mapping type), a precoding granularity, an identifier (e.g., scrambling identifier) associated with scrambling for PDCCH demodulation reference signals (DMRS), coded bits of DCI content, or any combination thereof.

[0100] In some aspects, a UE 115 may be configured with up to ten search space sets within a given BWP of a component carrier. In some aspects, each search space set may be associated with one CORESET, and may include a set of monitoring occasions. In some aspects, a search space set may include a set of control channel monitoring occasions. For example, a search space set may include a set of monitoring occasions, 32 with a monitoring occasion occurring at regular or irregular periodicities (e.g., monitoring occasion every 10 ms). The UE 115 may be configured to blindly decode signals received in the respective monitoring occasions to determine whether cyclic redundancy check (CRC) passes in the respective monitoring occasions. Moreover, a UE 115 may be configured to determine the control channel monitoring occasions associated with a given search space set based on one or more characteristics of the search space set which may be configured (e.g., pre-configured) at the UE 115, indicated to the UE 115 via a network entity 105 (e.g., via RRC signaling), or both. A UE 115 may be configured with one or more different types of search space sets (e.g., searchSpaceType), including UE-specific search space sets, common search space sets, or both. Additionally, each search space set may be associated with one or more DCI formats which are to be monitored.

[0101] Parameters of a search space set (s) may include a periodicity ( k_s ) of monitoring occasions (e.g., k_s slots), an offset (o_s) for monitoring occasions in units of slots (e.g., o_s slots) (e.g., monitoringSlotPeriodicityAndOffset), a duration (T_s) indicative of a quantity of slots within a period in which the search space set exists (where T_s < k_s), or any combination thereof. A UE 115 of the wireless communications system 100 may determine a number/quantity of PDCCH monitoring occasions (e.g., PDCCH candidates) within a slot

and a frame

modk_s = 0. In some aspects, when monitoring a control channel, a UE 115 may be configured to monitor control channel candidates (e.g., PDCCH candidates) for a search space set s for T_s consecutive slots, starting from slot h^, and may refrain from monitoring control channel candidates for the search space set s for the next k_s — T_s consecutive slots. Quantities of control channel candidates (e.g., PDCCH candidates) may be based on an aggregation level (e.g., number of CCEs) of wireless communications at the UE 115.

[0102] These search space set parameters may be configured (e.g., pre-configured) at the UE 115, indicated to the UE 115 via a network entity 105 (e.g., via RRC signaling), or both. For example, RRC signaling may be used to configure parameters of a search space set at a UE 115, including with which CORESET the search space set is associated, a periodicity of monitoring occasions of the search space set, an offset of the 33 monitoring occasions, DCI formats to monitor, a number of PDCCH candidates for a given aggregation level of the search space set, and the like.

[0103] Each search space set may be associated with a search space set index. In some implementations, PDCCH candidates may be defined as part of the search space set configuration. For example, a search space set include a set of PDCCH candidates, where each PDCCH candidate is associated with a given aggregation level and candidate index. In some aspects, a UE 115 may be configured to monitor PDCCH candidates in configured search space sets. The UE 115 may be configured to blindly decode the PDCCH candidates (e.g., monitoring occasions) within one or more search space sets. In cases where the UE 115 receive a DCI message within a PDCCH candidate, the UE 115 may identify a CRC pass for one or more of the candidates (e.g., successfully decoding), and the UE 115 may act in accordance with the received DCI message (e.g., perform a communication scheduled by the DCI message).

[0104] In some aspects, a UE 115 may be configured to monitor a control channel according to a control channel monitoring pattern (e.g., PDCCH monitoring pattern) within a slot (e.g., monitoringSymbolsWithinSlot). For example, a PDCCH monitoring pattern within a slot may indicate a first symbol(s) of a CORESET within a slot for PDCCH monitoring. For instance, in the context of a slot including fourteen symbols, a CORESET configured at a UE 115 may be associated with a search space set including three symbols, and a control channel monitoring pattern (e.g., monitoringSymbolsWithinSlot) associated with the search space set may be configured as “01000010001000.” In this example, the UE 115 may be configured to determine that there are three monitoring occasions (e.g., PDCCH candidates) within each slot that the search space set exists. Moreover, the UE 115 may be configured to determine that the three monitoring occasions begin at the second, seventh, and eleventh symbols of each respective slot that the search space exists.

[0105] In some aspects, multiple search space sets and/or multiple PDCCH candidates may be linked together in different search space sets (e.g., associated with one another) for possible repetitions of the same control channel transmission (e.g., repetitions of DCI). PDCCH candidates which are linked together may be used to transmit/receive repetitions of the same control message. In other words, PDCCH candidates may be linked together for “PDCCH repetitions.” In the context of PDCCH 34 repetitions, the payload (e.g., DCI payload) received within two PDCCH candidates (e.g., two PDCCH repetitions) may be the same. For example, a first PDCCH candidate may be related to, or linked with, to a second PDCCH candidate. In this example, a first repetition of DCI may be transmitted in the first PDCCH candidate, and a second repetition of DCI may be transmitted in the second PDCCH candidate, where the first and second repetitions of DCI are the same. In this example, a UE 115 may receive and/or decode only the first repetition of DCI or only the second repetition of DCI. Additionally or alternatively, the UE 115 may receive and/or decode both the first and second repetitions of DCI by performing soft-combining of the first and second repetitions of DCI, and the UE may be aware of the linking before decoding. In some aspects, related/linked PDCCH candidates may have the same aggregation level (e.g., same number of CCEs). In some cases, PDCCH candidates with the same aggregation level and same candidate index in the two linked search space sets may be linked, where the two linked search space sets may be configured with the same number of candidates for each aggregation level.

[0106] In some wireless communications systems which support SFN communications, a single PDCCH transmission (e.g., PDCCH DMRS) may be associated with two TCI states. In particular, for SFN PDCCH transmissions, one CORESET may be activated at UE 115 with two active TCI states. In such cases, each control channel candidate (e.g., PDCCH candidate) of a search space set associated with the CORESET may be associated with the two active TCI states of the CORESET. Moreover, each PDCCH transmission may be associated with two TCI states in all REGs and CCEs of the PDCCH transmission. As compared to linked search space candidates configured for PDCCH repetition, in SFNed PDCCH transmissions (e.g., PDCCH transmissions associated with CORESETs with two or more TCI states), there is no linking between TCI states, as each PDCCH candidate is defined in one search space set and one CORESET.

[0107] In some aspects, related PDCCH candidates in different search space sets which are associated with corresponding CORESETs may be linked together (e.g., related) for PDCCH repetition. In some cases, two PDCCH candidates with a same candidate index across two related search space sets may be linked or related. In some cases, two search space sets may be linked by RRC configuration. In some cases, the 35 measurement occasions of the two linked search space sets are one-to-one mapped. In some cases, PDCCH candidates with a same start CCE index may be linked. Moreover, UEs 115 may be configured with sets of linked/related PDCCH candidates which are within a same slot or TTI (e.g., intra-slot PDCCH repetition which may be time division multiplexed or time-overlapping), sets of linked/related PDCCH candidates which are in different slots (e.g., intra-slot PDCCH repetition), or both.

[0108] The wireless communications system 100 may be configured to support inter-carrier scheduling (e.g., cross-carrier scheduling), intra-carrier scheduling (e.g., self-scheduling), or both. Inter-carrier scheduling, or cross-carrier scheduling, refers to cases in which control signaling transmitted/received on a first component carrier (e.g., scheduling component carrier, scheduling cell) is used to schedule communications (e.g., physical downlink shared channel (PDSCH), physical uplink shared channel (PUSCH)) on a different component carrier (e.g., scheduling component carrier, scheduling cell). Conversely, intra-carrier scheduling, or self-scheduling, refers to cases in which control signaling transmitted/received on a component carrier is used to schedule communications on the same component carrier (e.g., same cell).

[0109] In some aspects, a search space set may include control channel candidates (e.g., PDCCH candidates) which are configured for self-scheduling, cross-carrier scheduling, or both. The CCEs associated with control channel candidates for different scheduled component carriers (e.g., PDCCH candidates for self-scheduling, PDCCH candidates for cross-carrier scheduling) within a monitoring occasion of a search space set may be separately identified based on a number of candidates for each aggregation level. The number/quantity of candidates for each aggregation level may be configured in a scheduled component carrier, and may be monitored in the scheduling component carrier. For example, a monitoring occasion for a search space set includes a set of PDCCH candidates with an aggregation level of two (e.g., two CCEs for each PDCCH candidate). In this example, the set of PDCCH candidates may include a first subset of PDCCH candidates configured for self-scheduling (e.g., subset of PDCCH candidates with CIF=0), and a second subset of PDCCH candidates for cross-carrier scheduling (e.g., subset of PDCCH candidates with CIF=1). In this regard, a single search space set may include PDCCH candidates which are configured for self-scheduling, cross-carrier scheduling, or both. 36

[0110] As noted herein, in some wireless communications systems, downlink control messages (e.g., DCI messages) may schedule communication of other downlink messages (e.g., PDSCH messages) from a network entity 105 to a UE 115. The UE 115 may be configured to determine what QCL assumption (e.g., QCL parameters or QCL type properties, beam parameters, transmission configuration indicator (TCI) state, and the like) is to be used for receiving the scheduled downlink PDSCH message based on the downlink control message. For example, the QCL assumption used for receiving the downlink control message may also be used for the scheduled downlink PDSCH message or another QCL assumption may be used.

[0111] In some cases, the UE 115 may monitor one or more CORESETs for multiple linked control channel candidates (e.g., PDCCH candidates). That is, the control channel candidates may be linked for multiple repetitions of the same downlink control message. For example, a same DCI payload may be transmitted via two (or more) PDCCH candidates in a slot (e.g., the PDCCH candidates may overlap in time).

In some examples, each of the control channel candidates may be associated with one or more QCL assumptions. Additionally or alternatively, the scheduled PDSCH may be associated with one or more QCL assumptions. However, some wireless communications systems may not provide a UE 115 with a mechanism for determining which QCL assumptions should be used for monitoring or receiving one or more CORESETs, a shared data channel, or both.

[0112] Accordingly, the techniques described herein may enable devices in a wireless communications system to implement one or more priority rules for allocating receive beams for various communications. For example, a UE 115 may receive control signaling indicating that the UE 115 is to monitor one or more CORESETs. Additionally, the UE 115 may receive a control message scheduling a downlink message (e.g., a PDSCH message). In some examples, the downlink message may overlap in time with the one or more control resource sets. The UE 115 may monitor the downlink message (e.g., the shared data channel), the one or more CORESETs, or a combination thereof in accordance with a priority rule. The priority rule may indicate which QCL assumptions for the UE 115 to use for monitoring the control resource sets, the downlink message, or both. 37

[0113] In some examples, the downlink message may correspond to one or more TCI states. The priority rule may indicate which QCL assumptions the UE 115 should use to monitor the one or more CORESETs in addition or alternative to the downlink message. As an illustrative example, the UE 115 may be capable of reception via two beams (e.g., the UE 115 may implement up to two QCL assumptions for monitoring or receiving communications). The UE 115 may be indicated to monitor one or more CORESETs associated with one or more QCL assumptions (e.g., a single CORESET associated with one or more QCL assumptions, two CORESETs each associated with a respective QCL assumption, and so on). Further, the UE 115 may be indicated to monitor the downlink message associated with a TCI. In other words, the UE 115 may be capable of reception using up to two QCL assumptions but may be indicated to monitor the CORESETs and downlink message using one, two, three, or four QCL assumptions in a same time period (e.g., in a slot). Thus, the UE 115 may identify the QCL assumptions for monitoring (or refraining from monitoring) the CORESETs and downlink message based on the one or more priority rules indicating the QCL assumptions for a respective scenario. For example, a priority rule may indicate the QCL assumptions to use when the downlink message corresponds to one or more different QCL assumptions as the one or more CORESETs, when the downlink message corresponds to one or more of the same QCL assumptions as the one or more CORESETs, or any combination thereof, among other examples described herein. By implementing such priority rules, the UE 115 may efficiently allocate receive beams to receive the various communications (e.g., CORESETs, downlink messages, or both), which may result in improved communications efficiency, reliability, or both. For example, such priority rules may enable the UE 115 to prioritize CORESETs (e.g., improve PDCCH reliability or throughput), efficiently use beams to receive multiple CORESETs/PD SCHs, or any combination thereof, among other examples of potential benefits.

[0114] FIG. 2 illustrates an example of a wireless communications system 200 that supports quasi co-location prioritization for wireless communications systems in accordance with aspects of the present disclosure. In some examples, wireless communications system 200 may implement, or be implemented by, aspects of wireless communications system 100. For example, the wireless communications system 200 38 may include a UE 115-a and a network entity 105-a, which may be examples of the corresponding devices described herein with reference to FIG. 1.

[0115] The UE 115-a may communicate with the network entity 105-a using a communication link 205, which may be an example of an NR or LTE link between the UE 115-a and the network entity 105-a. In some cases, the communication link 205 between the UE 115-a and the network entity 105-a may include an example of an access link (e.g., Uu link) which may include a bi-directional link that enables both uplink and downlink communication. For example, the UE 115-a may transmit uplink signals, such as uplink control signals or uplink data signals, to the network entity 105-a using the communication link 205 and the network entity 105-a may transmit downlink signals, such as downlink control signals or downlink data signals, to the UE 115-a using the communication link 205.

[0116] In some examples, the UE 115-a and the network entity 105-b of the wireless communications system 200 may support techniques for scheduling communications (e.g., downlink messages 220) at the UE 115-a using control channel repetition (e.g., PDCCH repetition) as described herein with reference to FIG. 3. For example, the network entity 105-b may send a control message 315-a and a control message 315-b including a same DCI payload scheduling the downlink message 320. By implementing such repetition (e.g., transmitting two PDCCH candidates on different resources that may be TDM or time overlapping or frequency overlapping or any combination thereof), the wireless communications system 200 may realize improved communications reliability, robustness, etc.

[0117] In some examples, the wireless communications system 200 may support multiple QCL assumptions (e.g., QCL parameters, QCL properties, QCL type D properties or properties of other QCL types, and the like). For example, the wireless communications system 200 may support multiple QCL-TypeD properties. In some examples, the UE 115-a may not receive multiple beams (e.g., different QCL-type D properties) simultaneously in a respective serving cell or on multiple serving cells in a same frequency band with carrier aggregation (CA) operation. For example, the UE 115-a may be configured with a priority rule (e.g., pre-configured, signaled via control signaling, and the like). The priority rule may indicate that if a UE 115-a is configured for single cell operation or for operation with CA in a same frequency band, and the UE 39

115-a monitors PDCCH candidates in overlapping PDCCH monitoring occasions in multiple CORESETs that have same or different QCL-TypeD properties on active DL BWP of a cell from the one or more cells, then the EE may 115-a may monitor PDCCHs in a CORESET, and in any other CORESET from the multiple CORESETs having same QCL-TypeD properties as the CORESET, on the active downlink BWP of a cell from the one or more cells. The CORESET may correspond to the common search space (CSS) set with the lowest index in the cell with the lowest index containing CSS, if any, otherwise to the EE specific search space (USS) set with the lowest index in the cell with lowest index. The lowest EiSS set index may be determined over all USS sets with at least one PDCCH candidate in overlapping PDCCH monitoring occasions. Although an example of a priority rule is given above, the priority rule may be configured for any of the rules, scenarios, schemes, QCL assumption prioritizations, or any combination thereof as described herein.

[0118] In some examples, for PDCCH and PDSCH, if a QCL-typeD of a PDSCH DMRS is different from that of the PDCCH DMRS with which they overlap in at least one symbol, the EE 115-a may be expected to prioritize the reception of PDCCH associated with that CORESET. This may also apply to the intra-band CA case (e.g., when PDSCH and the CORESET are in different component carriers). In some examples, such a rule may be defined for the case that the offset between the reception of the downlink DCI (e.g., scheduling DCI) and the scheduled PDSCH is less than or equal to a threshold (e.g., timeDurationForQCL).

[0119] In some examples, the wireless communications system 200 may support SFN communications. For example, the network entity 105-a may simultaneously transmit a same PDCCH from multiple TRPs (e.g., two TRPs) on the same time and frequency resources. Stated alternatively, the wireless communications system 200 may support a scheme of PDCCH transmission from multiple TRPs based on SFN transmission. Such SFN communications may improve a reliability of control messaging (e.g., a PDCCH message may realize improved reliability in high mobility situations such as high speed train scenarios, high blockage scenarios, and the like). In some examples, a CORESET for SFN communications may be RRC configured with a higher layer parameter to indicate that DCI or PDCCH received on this CORESET is SFN communications. Additionally or alternatively, the EE 115-a may receive other 40 configuration messages such as a MAC-CE activation command to indicate two TCI states for a CORESET. In some examples, a single CORESET may be configured with two active TCI states (e.g., all PDCCH candidates in a given search space (SS) set may be associated with both TCI states of the CORESET).

[0120] In some examples, the wireless communications system 200 may support reception via multiple beams at the UE 115-a. For example, the UE 115-a may be configured with two different beams to monitor overlapping CORESETs. In such examples, the UE 115-a may support identifying two QCL assumptions (e.g., two QCL- TypeD properties) for multiple overlapping CORESETs. In other words, the wireless communications system 200 may schedule or configure communications such that overlapping PDCCHs may have different QCL assumptions (e.g., QCL typeD properties or properties of other QCL types) for time overlapping PDCCH repetition or with a CORESET with two QCL assumptions (e.g., for SFN PDCCH). However, in some cases the UE 115-a may not have with a mechanism for determining which QCL assumptions (e.g., two QCL assumptions) should be used for monitoring or receiving one or more CORESETs associated with multiple QCL assumptions, a shared data channel associated with one or more QCL assumptions, or any combination thereof (e.g., the one or more CORESETs and the shared data channel may overlap in time).

[0121] Accordingly, aspects of the present disclosure provide techniques that enable devices in the wireless communications system 200 to implement one or more priority rules for allocating receive beams for various communications. For example, the UE 115-a may receive control signaling 210 indicating that the UE 115-a is to monitor one or more CORESETs. Additionally, the UE 115-a may receive a control message 215-a or control message 215-b or both scheduling a downlink message 220 (e.g., a PDSCH message). In some examples, the downlink message 220 may overlap in time with the one or more CORESETs. The UE 115-a may monitor the downlink message 220 (e.g., the shared data channel), the one or more CORESETs, or a combination thereof in accordance with a priority rule. The priority rule may indicate which QCL assumptions for the UE 115-a to use for monitoring the control resource sets, the downlink message, or both.

[0122] In some examples, the downlink message 220 may correspond to a single TCI state. In such examples, the UE 115-a may identify QCL assumptions for 41 monitoring the various communications based on the priority rule indicating the QCL assumptions for a respective scenario. Additionally or alternatively, the downlink message 220 may correspond to multiple (e.g., two) TCI states. For example, the multiple TCI states may be applied in spatial division multiplexing (SDM) (e.g., to different layers), FDM (e.g., to different resource blocks (RBs), TDM (e.g., to different symbols), or any combination thereof. In some examples, a PDSCH having two TCI states may correspond to a single DCI based multi-TRP feature as described herein, where each TCI codepoint of DCI indicates one or two TCI states (e.g., when it indicates two TCI states, the PDSCH may have two TCI states based on SDM, FDM, or TDM schemes). Additionally or alternatively, the downlink message 220 may be an example of a SFN PDSCH where each DMRS port and data layer may be associated with two TCI states (e.g., similar to a SFN PDCCH). In some examples, an offset between the reception of a downlink DCI (e.g., a scheduling DCI) and the scheduled PDSCH may be less than a threshold (e.g., a threshold timeDurationForQCL). The UE 115-a may identify one or more default beams based on the offset being less than the threshold, the one or more priority rules, or a combination thereof. For example, the UE 115-a may identify two default beams as the two TCI states corresponding to the lowest TCI codepoint that is mapped to the two TCI states (e.g., in the case when the UE 115-a is configured with a parameter enableTwoDefaultTCI-States) .

[0123] The UE 115-a may identify the QCL assumptions for monitoring (or refraining from monitoring) the CORESETs and downlink message 220 based on the one or more priority rules indicating the QCL assumptions for a respective scenario. For example, a priority rule may indicate the QCL assumptions to use when the downlink message 220 corresponds to one or more different QCL assumptions as the one or more CORESETs, when the downlink message corresponds to one or more of the same QCL assumptions as the one or more CORESETs, or any combination thereof, among other examples described herein with reference to FIGs. 4 and 5. By implementing such priority rules, the UE 115-a may efficiently allocate receive beams to receive the various communications (e.g., CORESETs, downlink messages 220, or both), which may result in improved communications efficiency, reliability, or both, among other potential benefits. 42

[0124] FIG. 3 illustrates an example of a resource configuration 300 that supports quasi co-location prioritization for wireless communications systems in accordance with aspects of the present disclosure. Aspects of the resource configuration 300 may implement, or be implemented, by wireless communications systems 100, 200, or both.

[0125] As noted previously herein, multiple search space sets 305 may be linked together for control channel repetition (e.g., PDCCH repetition). For example, as shown in the resource configuration 300, a first search space set 305 -a may be linked to a second search space set 305-b. In particular, monitoring occasions 310 associated with the first search space set 305-a (e.g., monitoring occasions 310-a, 310-b, 310-e, 310-f) may be linked with monitoring occasions 310 associated with the second search space set 305-b (e.g., monitoring occasions 310-c, 310-d, 310-g, 310-h). In some aspects, related PDCCH candidates in the respective search space sets 305 (e.g., PDCCH candidates within the monitoring occasions 310 of the respective search space sets 305) which are associated with corresponding CORESETs may be linked together (e.g., related) for PDCCH repetition. In other words, linked search space sets (e.g., search space sets 305-a, 305-b) may be associated with corresponding CORESETs (e.g., first CORESET, second CORESET, respectively). Moreover, the respective CORESETs corresponding to the respective search space sets 305-a, 305-b may be configured/activated with different TCI states (e.g., each CORESET may be activated with one or two TCI states).

[0126] In some cases, two PDCCH candidates with a same candidate index across two related search space sets may be linked or related. In other cases, PDCCH candidates with a same start CCE index may be linked. Moreover, UEs 115 may be configured with sets of linked/related PDCCH candidates which are within a same slot or TTI (e.g., intra-slot PDCCH repetition), sets of linked/related PDCCH candidates which are in different slots (e.g., intra-slot PDCCH repetition), or both. As an illustrative example of PDCCH repetition, each repetition may be a PDCCH candidate and two PDCCH candidates may be linked together for repetition of the same DCI. The two linked PDCCH candidates may be in different search space sets 305 (e.g., the two search space sets 305-a and 305-b may be associated with corresponding CORESETs and the two or more CORESETs may be configured or activated with different TCI states). 43

[0127] Associations (e.g., links) between search space sets 305 and/or between PDCCH candidates may be configured (e.g., pre-configured) at the UE 115, signaled to the UE 115 by the network entity 105 (e.g., via RRC signaling), or both. For example, a UE 115 may receive an RRC message which indicates that a first PDCCH candidate in the first search space set 305-a is linked with (e.g., related to) a second PDCCH candidate in the second search space set 305-b. By way of another example, a UE 115 may receive an RRC message which indicates that the first search space set 305-a is linked with (e.g., related to) a second search space set 305-b for PDCCH repetition. In this example, PDCCH candidates with the same aggregation level and same candidate index between the first and second search space sets 305 may be linked. In particular, the first search space set 305-a and the second search space set 305-b may include a first set of PDCCH candidates (first set of monitoring occasions 310) and a second set of PDCCH candidates (second set of monitoring occasions 310), respectively, where the first set of PDCCH candidates are linked to the second set of PDCCH candidates.

[0128] In some cases, the first and second sets of monitoring occasions 310 may include the same quantity of monitoring occasions/PDCCH candidates (e.g., one-to-one mapping of monitoring occasions). For example, the monitoring occasion 310-a associated with the first search space set 305-a may include the same quantities of PDCCH candidates as the monitoring occasion 310-c associated with the second search space set 305-b. Similarly, the monitoring occasions 310-b, 310-e, and 310-f associated with the first search space set may include the same quantities of PDCCH candidates as the monitoring occasions 310-d, 310-g, and 310-h associated with the second search space set 305-b, respectively. Moreover, the first and second search space 305-a, 305-b sets may be configured with the same quantity of PDCCH candidates for each aggregation level.

[0129] In some examples, aspects of the resource configuration 300 may support techniques for control channel repetition (e.g., PDCCH repetition) in the context of SFN communications, which may enable communications (e.g., PDSCH transmissions) to be scheduled at a UE 115 via control signaling transmitted/received on linked search space sets of a scheduling component carrier. In particular, aspects of the resource configuration 300 may enable UEs 115 to determine TCI state(s) for scheduled downlink messages in cases where repetitions of a scheduling downlink control 44 message occur in a set of PDCCH candidates linked across two search space sets 305 (and/or two CORESETs) which are associated with multiple TCI states (e.g., SFN CORESETs).

[0130] In some examples, aspects of the resource configuration 300 may support one or more priority rules for allocating receive beams for various communications as described herein. For example, a UE may receive control signaling indicating to monitor one or more CORESETs associated with the search space sets 305. The UE may receive a control message scheduling a downlink message (e.g., a shared data channel message). In some examples, the downlink message may overlap in time with the one or more CORESETs. The UE may monitor the downlink message (e.g., the shared data channel), the one or more CORESETs, or a combination thereof in accordance with a priority rule. The priority rule may indicate which QCL properties to use for monitoring the control resource sets, the downlink message, or both. By implementing such priority rules, the UE may efficiently allocate receive beams to receive the communications, which may result in improved communications efficiency, reliability, or both

[0131] FIG. 4 illustrates examples of priority schemes 400, 401, and 402 that support quasi co-location prioritization for wireless communications systems in accordance with aspects of the present disclosure. The priority schemes 400, 401, and 402 may implement, or be implemented by, aspects of the wireless communications systems 100 and 200, the resource configuration 300, or any combination thereof. For example, the priority schemes 400, 401, and 402 may illustrate examples of CORESETs 410 and shared data channel 415 communications between a UE a network entity as described herein.

[0132] A UE may receive control signaling indicating that the UE is to monitor one or more CORESETs 410. Additionally or alternatively, the UE may receive a control message scheduling a downlink message (e.g., a PDSCH message on the shared data channel 415 resources). In some examples, the downlink message may overlap in time with the one or more CORESETs 410. For example, a scheduled shared data channel 415 may be included in a same period of time (e.g., slot) as one or more CORESETs 410. 45

[0133] The UE may monitor for the downlink message (e.g., a shared data channel 415), the one or more CORESETs 410, or a combination thereof in accordance with one or more priority rules. A priority rule may indicate which QCL assumptions for the EE to use for monitoring the control resource sets, the downlink message, or both. In some examples, the UE may be pre-configured with the one or more priority rules. Additionally or alternatively, the UE may receive control signaling configuring the one or more priority rules.

[0134] As an illustrative example, the priority schemes 400, 401, and 402 may illustrate example scenarios or cases where a UE is capable of reception via two different beams, and the downlink message is associated with a single TCI state (e.g., a PDSCH with one QCL type-D assumption) and overlaps with various CORESETs 410, although it is to be understood the techniques described herein may be applied to any quantity of beams, monitoring occasions, TCI states, etc.

[0135] In the example priority scheme 400, the UE may be indicated to monitor one or more CORESETs 410 and a PDSCH message. For example, the UE may be indicated to monitor the CORESET 410-a associated with a first QCL assumption and the shared data channel 415-a associated with a second QCL assumption. In some examples, the first QCL assumption of the CORESET 410-a may be different than the second QCL assumption of the shared data channel 415-a. For example, the CORESET 410-a may have a first set of QCL-TypeD parameters (e.g., QCL-TypeD “x”) and the shared data channel 415-a may have a different second set of QCL-TypeD parameters (e.g., QCL- TypeD “y”). Although shown as a single CORESET 410-a associated with the first QCL assumption for illustrative clarity, any quantity of CORESETs 410 associated with the first QCL assumption may be used.

[0136] In some examples, the UE may prioritize the reception of PDCCH in the one or more CORESETs 410. For example, the UE may allocate the two receive beams (e.g., apply QCL parameters) to monitor the CORESET 410-a. Stated alternatively, each beam may use the first QCL assumption for the one or more CORESETs 410 based on a priority rule indicating that the UE is to apply the first QCL assumption to both beams for receiving the CORESETs 410 (e.g., the CORESET 410-a) when the CORESETs have a different QCL assumption than the shared data channel 415-a. In such examples, the UE may refrain from monitoring the shared data channel 415-a (e.g., the UE may 46 not allocate a beam for the shared data channel 415-a based on the priority rule indicating to use both beams for the CORESET 410-a). Such a priority rule (e.g., the prioritization of the CORESET 410-a) may improve reliability of a PDCCH message.

[0137] In some other examples, the UE may receive the PDCCH in the one or more CORESETs 410 in addition to the PDSCH with the different QCL assumption. For example, the UE may allocate a first beam with the first QCL assumption to monitor the CORESET 410-a and allocate a second beam with the second QCL assumption to receive the shared data channel 415-a (e.g., the UE may be capable of receiving with two QCL-TypeD, i.e., 2 receive beams). Stated alternatively, the UE may allocate the first beam (e.g., the first QCL assumption) for the one or more CORESETs 410 (e.g., the CORESET 410-a) and a second beam (e.g., the second QCL assumption) for the shared data channel 415-a based on a priority rule indicating such an allocation when the CORESETs have a different QCL assumption than the shared data channel 415-a. Such a priority rule may improve data throughput and enable the UE to receive both the CORESET 410-a and the shared data channel 415-a.

[0138] In the example priority scheme 401, the UE may be indicated to monitor the CORESET 410-b, the CORESET 410-c, and the shared data channel 415-b. As an illustrative example, the UE may be indicated to monitor the CORESET 410-a using a first QCL assumption (e.g., a first QCL-typeD “x”) and the CORESET 410-c using a second QCL assumption (e.g., a second QCL-typeD “y”) different than the first QCL assumption. The UE may also be indicated to monitor the shared data channel 415-b using a third QCL assumption.

[0139] In some examples, the third QCL assumption of the shared data channel 415-b may be different than both the first and second QCL assumptions (e.g., the third QCL assumption may be an example of a third QCL-TypeD “z”). In such examples, a priority rule may indicate that the UE is to prioritize the reception of the PDCCH in the CORESET 410-b and the CORESET 410-c. For example, the UE may allocate a first beam for monitoring the CORESET 410-b and the second beam for monitoring the CORESET 410-c. In such examples, the UE may not allocate a beam for the shared data channel 415-b. Stated alternatively, the priority rule may indicate the UE is to use the first QCL assumption of the CORESET 410-b and the second QCL assumption of the 47

CORESET 410-c based on the third QCL assumption being different than the first and second QCL assumptions.

[0140] In some other examples, the third QCL assumption of the shared data channel 415-b may be the same as one of the first or second QCL assumptions (e.g., the third QCL assumption may be an example of a third QCL-TypeD “x” or “y”). In such examples, a priority rule may indicate that the UE is to allocate a first beam to monitor the CORESET 410 and receive the shared data channel 415-b with the same QCL assumption and allocate a second beam to monitor the other CORESET 410. For example, the UE may allocate a first beam (e.g., use the first QCL assumption) for monitoring the CORESET 410-b and the shared data channel 415-b, and the UE may allocate a second beam (e.g., use the second QCL assumption) for monitoring the CORESET 410-c. In some of the examples described herein, the UE may monitor the CORESETs 410 (e.g., monitoring time frequency resources to potentially receive downlink control information) and receive the shared data channels 415 (e.g., receive scheduled PDSCH messages), though in some instances the term monitoring used herein may be referred to as receiving, and vice versa.

[0141] In the example priority scheme 402, the UE may be indicated to monitor the CORESET 410-d and receive the shared data channel 415-c. In some examples, the priority scheme 402 may be a similar priority scheme as priority scheme 401, except that the CORESET 410-d may be an example of a CORESET associated with two TCI states (e.g., a SFN CORESET 410). As an illustrative example, the UE may be indicated to monitor the CORESET 410-d using a first QCL assumption (e.g., a first QCL-typeD “x”) and a second QCL assumption (e.g., a second QCL-typeD “y”). The UE may also be indicated to receive the shared data channel 415-c using a third QCL assumption.

[0142] In some examples, the third QCL assumption of the shared data channel 415-c may be different than both the first and second QCL assumptions (e.g., the third QCL assumption may be an example of a third QCL-TypeD “z”). In such examples, a priority rule may indicate that the UE is to prioritize the reception of the PDCCH in the CORESET 410-d. For example, the UE may allocate a first beam for monitoring the CORESET 410-d and the second beam for monitoring the CORESET 410-d. In some such examples, the UE may not allocate a beam for the shared data channel 415-c.

Stated alternatively, the priority rule may indicate the UE is to use the first QCL 48 assumption and the second QCL assumption of the CORESET 410-d based on the third QCL assumption being different than the first and second QCL assumptions.

[0143] In some other examples, the third QCL assumption of the shared data channel 415-c may be the same as one of the first or second QCL assumptions (e.g., the third QCL assumption may be an example of a third QCL-TypeD “x” or “y”). In such examples, a priority rule may indicate that the UE is to allocate a first beam to monitor the CORESET 410-d and receive the shared data channel 415-c with the same QCL assumption, and allocate a second beam to also monitor the CORESET 410-d with the second different QCL assumption. For example, the UE may allocate a first beam (e.g., use the first QCL assumption) for monitoring the CORESET 410-d and receiving the shared data channel 415-c, and the UE may also allocate a second beam (e.g., use the second QCL assumption) for monitoring the CORESET 410-d.

[0144] In some examples of the SFN CORESET 410-d, the UE may receive downlink DCI (e.g., scheduling DCI) and the scheduled PDSCH may be less than a threshold (e.g., timeDurationForQCL). Thus, QCL-TypeD of the PDSCH may be based on a default QCL assumption (e.g., provided by higher layers). In some examples, the priority scheme 402 may be applied for intra-band CA (e.g., when the PDSCH and the CORESET 410-d are in difference component carriers).

[0145] FIG. 5 illustrates example priority schemes 500, 501, and 502 that support quasi co-location prioritization for wireless communications systems in accordance with aspects of the present disclosure. The priority schemes 500, 501, and 502 may implement, or be implemented by, aspects of the wireless communications systems 100 and 200, the resource configuration 300, or any combination thereof. For example, the priority schemes 500, 501, and 502 may illustrate examples of CORESETs 510 and shared data channel 515 communications between a UE a network entity as described herein.

[0146] A UE may receive control signaling indicating that the UE is to monitor one or more CORESETs 510. Additionally or alternatively, the UE may receive a control message scheduling a downlink message (e.g., a PDSCH message on the shared data channel 515 resources). In some examples, the downlink message may overlap in time with the one or more CORESETs 510. For example, a scheduled shared data channel 49

515 may be included in a same period of time (e.g., slot) as one or more CORESETs 510.

[0147] The UE may monitor for the downlink message (e.g., a shared data channel 415), the one or more CORESETs 510, or a combination thereof in accordance with one or more priority rules. A priority rule may indicate which QCL assumptions for the UE to use for monitoring the control resource sets, the downlink message, or both. In some examples, the UE may be pre-configured with the one or more priority rules. Additionally or alternatively, the UE may receive control signaling configuring the one or more priority rules.

[0148] As an illustrative example, the priority schemes 500, 501, and 502 may illustrate example scenarios or cases where a UE is capable of reception via two different beams, and the downlink message is associated with two TCI states (e.g., a PDSCH with two QCL type-D assumptions) and overlaps with various CORESETs 510, although it is to be understood the techniques described herein may be applied to any quantity of beams, monitoring occasions, TCI states, etc.

[0149] In the example priority scheme 500, the UE may be indicated to monitor one or more CORESETs 510 and a PDSCH message. For example, the UE may be indicated to monitor the CORESET 510-a associated with a first QCL assumption and receive the shared data channel 515-a associated with a second QCL assumption and a third QCL assumption. That is, the CORESET 510-a may correspond to a first set of QCL-TypeD parameters (e.g., QCL-TypeD “x”) and the shared data channel 515-a may correspond to a second set of QCL-TypeD parameters and a third set of QCL-TypeD parameters. Although shown as a single CORESET 510-a associated with the first QCL assumption for illustrative clarity, any quantity of CORESETs 510 associated with the first QCL assumption may be used.

[0150] In some examples, the UE may prioritize the reception of PDCCH in the one or more CORESETs 510. For example, the UE may allocate a first beam to monitor the CORESET 510-a (e.g., the UE may monitor the CORESETs 510 with one beam).

Stated alternatively, the beam may use the first QCL assumption for the one or more CORESETs 510 based on a priority rule indicating that the UE is to apply the first QCL assumption to at least the first beam for monitoring the CORESETs 510 when the 50

CORESETs have different QCL assumptions than the shared data channel 515-a. For example, the EE may monitor the CORESET 510-a by using the first QCL assumption of the CORESET 510-a for the first beam. In such examples, the UE may refrain from receiving the shared data channel 515-a (e.g., the UE may not allocate a beam for the shared data channel 515-a based on the priority rule indicating to use one or both beams for the CORESET 510-a). Such a priority rule may improve reliability of a PDCCH message.

[0151] In some other examples, the UE may receive the PDCCH in the one or more CORESETs 510 in addition to the PDSCH. For example, the second or third QCL assumption of the shared data channel 515-a may be the same as the first QCL assumption of the CORESET 510-a. As an illustrative example, the CORESET 510-a may correspond to QCL-typeD “x” and the shared data channel 515-a may correspond to QCL-typeD “x” and QCL-typeD “y ” Thus, the UE may use the first QCL assumption (e.g., QCL-typeD “x”) to monitor one or both of the CORESET 510-a and receive the shared data channel 515-a and the second QCL assumption (e.g., QCL- typeD “y”) to receive one or both of the CORESET 510-a and the shared data channel 515-a. In some examples, the UE may use a single beam for the shared data channel 515-a (e.g., the PDSCH may effectively become a single-beam PDSCH instead of a multi-TCI state PDSCH in such examples). For example, the priority rule may indicate to use the first QCL assumption to receive the CORESET 510-a, and the second QCL assumption to receive the shared data channel 515-a.

[0152] In the example priority scheme 501, the UE may be indicated to monitor the CORESET 510-b, the CORESET 510-c, and the shared data channel 515-b. As an illustrative example, the UE may be indicated to monitor the CORESET 510-a using a first QCL assumption (e.g., a first QCL-typeD “x”) and the CORESET 510-c using a second QCL assumption (e.g., a second QCL-typeD “y”) different than the first QCL assumption. The UE may also be indicated to monitor the shared data channel 515-b using a third QCL assumption and a fourth QCL assumption, which may each be the same or different from the first and second QCL assumptions.

[0153] In some examples, both the third QCL assumption and the fourth QCL assumption of the shared data channel 515-b may be different than both the first QCL assumption and the second QCL assumption. In some such examples, a priority rule 51 may indicate that the UE is to monitor the CORESETs 510 using the first and second QCL assumptions (e.g., prioritize the CORESETs 510). In some other examples, one of the third QCL assumption or the fourth QCL assumption of the shared data channel 515-b may be different than both the first and second QCL assumptions (e.g., the third QCL assumption may be an example of a third QCL-TypeD “x” and the fourth QCL assumption may be an example of a third QCL-TypeD “z”). In some such examples, a priority rule may indicate that the UE is to receive (e.g., monitor) the CORESET 510 and the shared data channel 515-b using the common QCL assumption (e.g., a first beam with QCL TypeD “x” that is the same for the CORESET 510-b and one of the TCI states of the shared data channel 515-b). The priority rule may indicate that the UE is to monitor the other CORESET 510 using the second QCL assumption (e.g., monitor the CORESET 510-c using the QCL TypeD “y”). In some examples, the PDSCH of the shared data channel 515-b may effectively become single-beam. In some other examples, the first QCL assumption of the CORESET 510-b may be the same as the third QCL assumption of the shared data channel 515-b, and the second QCL assumption of the CORESET 510-c may be the same as the fourth QCL assumption of the shared data channel 515-b. In such examples, the UE may use the first and second QCL assumptions to receive the CORESET 510-b, the CORESET 510-c, and both instances of the shared data channel 515-b based on the priority rule indicating such monitoring.

[0154] In the example priority scheme 502, the UE may be indicated to monitor the CORESET 510-d and the shared data channel 515-c. In some examples, the priority scheme 502 may be a similar priority scheme as priority scheme 501, except that the CORESET 510-d may be an example of a CORESET associated with two TCI states (e.g., a SFN CORESET 510). As an illustrative example, the UE may be indicated to monitor the CORESET 510-d using a first QCL assumption (e.g., a first QCL-typeD “x”) and a second QCL assumption (e.g., a second QCL-typeD “y”). The UE may also be indicated to receive the shared data channel 515-c using a third QCL assumption and a fourth QCL assumptions. Thus, anywhere between one and four QCL assumptions may be possible and the UE may use similar priority rules as the priority scheme 501 to efficiently select two QCL assumptions. For example, if each of the QCL assumptions are different, the UE may prioritize the two CORESET 510-d QCL assumptions, if one 52 or more of the QCL assumptions are the same the UE may use a same beam to receive both the CORESET 510-d and the shared data channel 515-c, or any combination thereof.

[0155] In some examples, the priority schemes 500, 501, 502 and the associated example priority rules may be conditioned on one or more of the following example factors. For example, the UE may receive downlink DCI (e.g., scheduling DCI) and the scheduled PDSCH may be less than a threshold (e.g., timeDurationForQCL). Thus, the QCL-TypeD of the PDSCH may be based on a default QCL assumption (e.g., provided by higher layers). In some examples, the priority scheme 502 may be applied for intra band CA (e.g., when the PDSCH and the CORESET 510-d are in difference component carriers). In some examples, the UE may be configured with two default beams (e.g., configured with enableTwoDefaultTCI-States) and the two QCL-TypeD of the PDSCH may be based on two TCI states corresponding to the lowest TCI codepoint that is mapped to 2 TCI states.

[0156] In some examples, the PDSCH in the priority schemes 500, 501, and 502 (e.g., the shared data channels 515) may be based on one or more multiplexing schemes, such as SDM, SFN, FDM, or TDM schemes for communications between the UE and the network entity. For example, the two QCL assumptions (e.g., QCL-TypeD) may be for different DMRS ports or data layers (e.g., SDM) or for the same DMRS port or data layers in same REs (e.g., SFN), or for different set of RBs (e.g., FDM) or for different sets of OFDM symbols (e.g., TDM), or any combination thereof, among other examples. In some cases, such as for TDM, the UE may alternatively apply aspects of the example priority schemes 400, 401, 402 to the scenarios of FIG. 5. For example, the UE may use priority rules described with reference to FIG. 4 per PDSCH repetition (e.g., even though PDSCH has two QCL-typeD, since different QCL-typeD may be applied to TDMed repetitions, the rules of FIG. 4 may be applied per repetition), and vice versa.

[0157] FIG. 6 illustrates an example of a process flow 600 that supports quasi co- location prioritization for wireless communications systems in accordance with aspects of the present disclosure. In some examples, process flow 600 may implement, or be implemented by, aspects of wireless communications systems 100 or 200, resource configuration 300, priority schemes as described with reference to FIGs. 4 and 5, or any 53 combination thereof. For example, the process flow 600 may illustrate a UE 115-b monitoring one or more CORESETs, a downlink message, or any combination thereof in accordance with one or more priority rules as described with reference to FIGs. 1-5.

[0158] In some cases, process flow 600 may include a UE 115-b and a network entity 105-b, which may be examples of corresponding devices as described herein. In some examples, the operations illustrated in process flow 600 may be performed by hardware (e.g., including circuitry, processing blocks, logic components, and other components), code (e.g., software) executed by a processor, or any combination thereof. Alternative examples of the following may be implemented, where some steps are performed in a different order than described or are not performed at all. In some cases, steps may include additional features not mentioned below, or further steps may be added. In some examples, operations performed at one device as described herein may additionally or alternatively be performed by other devices, and vice versa.

[0159] At 605, the UE 115-b may receive, from the network entity 105-b, control signaling indicating to the UE to monitor at least one CORESET. For example, the control signaling may be an example of RRC signaling or other control signaling indicating a SFN CORESET with multiple TCI states, a single CORESET corresponding to a respective TCI state, multiple CORESETs each corresponding to a respective TCI state, or any combination thereof. In this regard, the control signaling may configure the UE 115-b with multiple CORESETs including sets of PDCCH candidates which the UE 115-b is to monitor.

[0160] At 610, the UE 115-b may receive, from the network entity 105-b, a first control message (e.g., first repetition of a control message). In some aspects, the control message may schedule a downlink message (e.g., PDSCH transmission) from the network entity 105-b to the UE 115-b. The control message may include a DCI message (e.g., DCI formats 0 1, 0 2, 1 1, and/or 1 2) or other examples of control messages. In some examples, the control message may indicate a TCI state for the PDSCH message. In some other examples, the UE 115-b may use a default TCI state for the PDSCH message. In some cases, the PDSCH message may correspond to multiple TCI states.

[0161] In some examples, at 615 the UE 115-b may receive, from the network entity 105-b, a second control message (e.g., second repetition of the control message). In 54 some aspects, the second control message may schedule a downlink message from the network entity 105-b to the UE 115-b. The control message may include a DCI message (e.g., DCI formats 0 1, 0 2, 1 1, and/or 1 2). The first and second control messages (e.g., first and second repetitions of the control message) received at 610 and 615, respectively, may each schedule the same downlink message, and may include the same data payload. In some examples, the UE 115-b may perform soft combining of the first and second repetitions of the control message received at 610 and 615. In some aspects, the UE 115-b may perform soft combining (e.g., perform one or more soft combining procedures) in order to demodulate/decode the repetitions of the control message. In particular, the UE 115-b may perform soft combining of a first signal (e.g., first repetition of the control message) received at 610 with a second signal (e.g., second repetition of the control message) received at 615.

[0162] At 620, the UE 115-b, the network entity 105-b, or both, may identify one or more priority rules for monitoring the at least one CORESET, the downlink message(s), or any combination thereof. For example, based on the priority rules, the UE 115-b may monitor one or more of the at least one CORESETs using a first QCL assumption, a second QCL assumption or both. The UE 115-b may additionally or alternatively monitor the downlink message (e.g., shared data channel) using the first QCL assumption, the second QCL assumption, a third QCL assumption, or a fourth QCL assumption as described herein with reference to FIGs. 4 and 5, although any configuration or examples of priority rules may be used to configure the UE 115-b to select beams (e.g., QCL parameters) for prioritizing the CORESETs and/or the downlink message. In some examples, the one or more priority rules may be pre- configured at the UE 115-b, signaled to the UE 115-b via a control signal at 605 (or another control signal), or any combination thereof. Thus, at 625 the UE 115-b may monitor in accordance with the identified priority rule(s).

[0163] At 630, the network entity 105-b may transmit one or more CORESETs to the UE 115-b. Additionally, at 645 the network entity 105-b may transmit a downlink message to the UE 115-b. In some examples, the one or more CORESETs and the downlink message may overlap in time or otherwise share a time duration (e.g., a slot).
