[0002] Aspects of the present disclosure generally relate to wireless communications and to techniques and apparatus for quasi-co-location (QCL) prioritization rules for control channel repetition. [Background technology]

[0003] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems may utilize multiple-access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple-access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single-carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and Long Term Evolution (LTE). LTE / LTE-Advanced is a set of extensions to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the 3rd Generation Partnership Project (3GPP®).

[0004] A wireless network may include several base stations (BSs) that can support communication for several user equipments (UEs). The UEs may communicate with the BSs via a downlink and an uplink. The "downlink" (or "forward link") refers to the communication link from the BS to the UE, and the "uplink" (or "reverse link") refers to the communication link from the UE to the BS. As described in more detail herein, a BS may be referred to as a Node B, gNB, access point (AP), radio head, transmit receive point (TRP), New Radio (NR) BS, 5G Node B, etc.

[0005] The above multiple access technologies have been adopted in various telecommunications standards to provide common protocols that enable various user equipment to communicate at city, national, regional, and even global levels. NR, sometimes referred to as 5G, is a set of extensions to the LTE mobile standard promulgated by 3GPP. NR is designed to improve spectral efficiency, reduce costs, improve service, utilize new spectrum, and better support mobile broadband Internet access by using orthogonal frequency division multiplexing (OFDM) with cyclic prefix (CP-OFDM) on the downlink (DL) and CP-OFDM and / or SC-FDM (e.g., also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL) to better integrate with other open standards, as well as by supporting beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation. As demand for mobile broadband access continues to grow, further improvements in LTE, NR, and other radio access technologies remain useful. Summary of the Invention [Means for solving the problem]

[0102] Various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure may be embodied in many different forms and should not be construed as limited to any specific structure or function presented throughout this disclosure. Rather, these aspects are intended so that this disclosure will be exhaustive and complete, and will fully convey the scope of the disclosure to those skilled in the art. Based on the teachings herein, those skilled in the art will appreciate that the scope of the present disclosure encompasses any aspect of the present disclosure disclosed herein, whether implemented independently or in combination with any other aspect of the present disclosure. For example, an apparatus may be implemented or a method may be practiced using any number of the aspects described herein. Additionally, the scope of the present disclosure is intended to encompass such apparatuses or methods practiced using other structure, functionality, or structure and functionality in addition to or other than the various aspects of the disclosure described herein. It should be understood that any aspect of the present disclosure disclosed herein may be embodied by one or more elements of a claim.

[0103] Several aspects of telecommunications systems are now presented with reference to various apparatus and techniques. These apparatus and techniques are described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements may be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends on the particular application and design constraints imposed on the overall system.

[0104] It should be noted that although aspects may be described herein using terminology commonly associated with 5G or NR radio access technologies (RATs), aspects of the present disclosure may apply to other RATs, such as 3G RATs, 4G RATs, and / or post-5G (e.g., 6G) RATs.

[0105] FIG. 1 illustrates an example wireless network 100 according to the present disclosure. The wireless network 100 may be an element of or include a 5G (NR) network and / or an LTE network, among other examples. The wireless network 100 may include several base stations 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d) as well as other network entities. A base station (BS) is an entity that communicates with user equipment (UE) and may also be referred to as an NR BS, Node B, gNB, 5G Node B (NB), access point, transmit reception point (TRP), etc. Each BS may provide communication coverage for a particular geographic area. In 3GPP, the term “cell” can refer to the coverage area of ​​a BS and / or the BS subsystem serving this coverage area, depending on the context in which the term is used.

[0106] A BS may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., a few kilometers in radius) and may allow unrestricted access by UEs with a service subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs with a service subscription. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by UEs that have an association with the femto cell (e.g., a UE in a Closed Subscriber Group (CSG)). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. In the example shown in FIG. 1, BS 110a may be a macro BS for macro cell 102a, BS 110b may be a pico BS for pico cell 102b, and BS 110c may be a femto BS for femto cell 102c. A BS may support one or more (e.g., three) cells. The terms "eNB," "base station," "NR BS," "gNB," "TRP," "AP," "Node B," "5G NB," and "cell" may be used interchangeably herein.

[0107] In some aspects, the cells may not necessarily be stationary, and the geographic area of ​​the cells may move according to the location of the mobile BS. In some aspects, the BSs may be interconnected to each other and / or to one or more other BSs or network nodes (not shown) in wireless network 100 through various types of backhaul interfaces, such as direct physical connections or virtual networks, using any suitable transport network.

[0108] Wireless network 100 may also include relay stations. A relay station is an entity that can receive data transmissions from an upstream station (e.g., a BS or UE) and send the data transmissions to a downstream station (e.g., a UE or BS). A relay station may also be a UE that can relay transmissions for other UEs. In the example shown in FIG. 1, relay BS 110d may communicate with BS 110a and UE 120d to facilitate communication between macro BS 110a and UE 120d. A relay BS may also be called a relay station, a relay base station, a relay, etc.

[0109] Wireless network 100 may be a heterogeneous network including different types of BSs, such as macro BSs, pico BSs, femto BSs, relay BSs, etc. These different types of BSs may have different transmit power levels, different coverage areas, and different susceptibility to interference in wireless network 100. For example, a macro BS may have a high transmit power level (e.g., 5-40 watts), while a pico BS, femto BS, and relay BS may have a lower transmit power level (e.g., 0.1-2 watts).

[0110] Network controller 130 may couple to a set of BSs and may provide coordination and control for these BSs. Network controller 130 may communicate with the BSs via a backhaul. The BSs may also communicate with each other directly or indirectly, e.g., via wireless or wireline backhaul.

[0111] The UEs 120 (e.g., 120a, 120b, 120c) may be dispersed throughout the wireless network 100, and each UE may be fixed or mobile. A UE may also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, etc. A UE may be a cellular phone (e.g., a smartphone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or equipment, a biometric sensor / device, a wearable device (smartwatch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet)), an entertainment device (e.g., a music or video device, or satellite radio), a vehicle part or sensor, a smart meter / sensor, industrial manufacturing equipment, a global positioning system device, or any other suitable device configured to communicate over a wireless or wired medium.

[0112] Some UEs may be considered machine type communication (MTC) UEs or evolved or enhanced machine type communication (eMTC) UEs. MTC UEs and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, and / or location tags that may communicate with a base station, another device (e.g., a remote device), or some other entity. A wireless node may provide, for example, connectivity for or to a network (e.g., a wide area network such as the Internet or a cellular network) via a wired or wireless communication link. Some UEs may be considered Internet of Things (IoT) devices and / or may be implemented as NB-IoT (narrowband Internet of Things) devices. Some UEs may be considered customer premises equipment (CPE). The UE 120 may be included within a housing that houses components of the UE 120, such as a processor component and / or a memory component. In some aspects, the processor component and the memory component may be coupled to each other. For example, a processor component (e.g., one or more processors) and a memory component (e.g., memory) may be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0113] In general, any number of wireless networks may be deployed within a given geographic area. Each wireless network may support a particular RAT and may operate on one or more frequencies. A RAT may also be referred to as a radio technology, air interface, etc. A frequency may also be referred to as a carrier, frequency channel, etc. Each frequency may support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, an NR network or a 5G RAT network may be deployed.

[0114] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly (e.g., without using base station 110 as an intermediary for communicating with each other) using one or more sidelink channels. For example, the UEs 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (which may include, e.g., vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, etc.), and / or mesh networks. In this case, the UEs 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by base station 110.

[0115] The devices of the wireless network 100 may communicate using an electromagnetic spectrum, which may be subdivided into various classes, bands, channels, etc. based on frequency or wavelength. For example, the devices of the wireless network 100 may communicate using an operating band having a first frequency range (FR1), which may range from 410 MHz to 7.125 GHz, and / or may communicate using an operating band having a second frequency range (FR2), which may range from 24.25 GHz to 52.6 GHz. Frequencies between FR1 and FR2 are sometimes referred to as mid-band frequencies. Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to as the “sub-6 GHz” band. Similarly, FR2 is often referred to as the “millimeter wave” band, even though it is different from the extremely high frequency (EHF) band (30 GHz to 300 GHz), which is identified as the “millimeter wave” band by the International Telecommunications Union (ITU). Thus, unless otherwise specified, it should be understood that terms such as "sub-6 GHz," as used herein, can broadly refer to frequencies below 6 GHz, frequencies within FR1, and / or mid-band frequencies (e.g., greater than 7.125 GHz). Similarly, unless otherwise specified, it should be understood that terms such as "millimeter wave," as used herein, can broadly refer to frequencies within the EHF band, frequencies within FR2, and / or mid-band frequencies (e.g., less than 24.25 GHz). The frequencies included in FR1 and FR2 may be modified, and it is contemplated that the techniques described herein are applicable to those modified frequency ranges.

[0116] As indicated above, Figure 1 is given as an example. Other examples may differ from the example described with respect to Figure 1.

[0117] 2 is a diagram illustrating an example base station 110 200 in communication with a UE 120 in wireless network 100 in accordance with the present disclosure. Base station 110 may be equipped with T antennas 234a through 234t, and UE 120 may be equipped with R antennas 252a through 252r, where in general T≧1 and R≧1.

[0118] At the base station 110, the transmit processor 220 may receive data for one or more UEs from a data source 212, select one or more modulation and coding schemes (MCSs) for each UE based at least in part on a channel quality indicator (CQI) received from the UE, process (e.g., encode and modulate) the data for each UE based at least in part on the MCS selected for the UE, and provide data symbols to all UEs. The transmit processor 220 may also process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and / or higher layer signaling) and provide overhead and control symbols. The transmit processor 220 may also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signals (PSS) or secondary synchronization signals (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on ​​the data symbols, control symbols, overhead symbols, and / or reference symbols, if applicable, and may provide T output symbol streams to T modulators (MODs) 232a through 232t. Each modulator 232 may process a respective output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modulator 232 may further process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. The T downlink signals from modulators 232a through 232t may be transmitted via T antennas 234a through 234t, respectively.

[0119] At UE 120, antennas 252a through 252r may receive downlink signals from base station 110 and / or other base stations and may provide received signals to demodulators (DEMODs) 254a through 254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) its received signal to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 may obtain received symbols from all R demodulators 254a through 254r, perform MIMO detection on the received symbols if applicable, and provide detected symbols. A receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 120 to a data sink 260, and provide decoded control information and system information to controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. A channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and / or a CQI parameter, among other examples. In some aspects, one or more components of the UE 120 may be included in the housing 284.

[0120] The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292. The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with the base station 110 via the communication unit 294.

[0121] Antennas (e.g., antennas 234a-234t and / or antennas 252a-252r) may include or be contained within one or more antenna panels, antenna groups, sets of antenna elements, and / or antenna arrays, among other examples. An antenna panel, antenna group, set of antenna elements, and / or antenna array may include one or more antenna elements. An antenna panel, antenna group, set of antenna elements, and / or antenna array may include a set of coplanar antenna elements and / or a set of non-coplanar antenna elements. An antenna panel, antenna group, set of antenna elements, and / or antenna array may include antenna elements within a single housing and / or antenna elements within multiple housings. An antenna panel, antenna group, set of antenna elements, and / or antenna array may include one or more antenna elements coupled to one or more transmitting and / or receiving components, such as one or more components of FIG. 2.

[0122] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI) from the controller / processor 280. The transmit processor 264 may also generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266, if applicable, further processed by modulators 254a through 254r (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to the base station 110. In some aspects, a modulator and demodulator (e.g., MOD / DEMOD 254) of the UE 120 may be included within a modem of the UE 120. In some aspects, the UE 120 includes a transceiver. The transceiver may include any combination of antennas 252, modulators and / or demodulators 254, MIMO detectors 256, receive processors 258, transmit processors 264, and / or TX MIMO processors 266. The transceiver, via a processor (e.g., controller / processor 280) and memory 282, may be used to implement any aspects of the methods described herein.

[0123] At the base station 110, uplink signals from the UE 120 and other UEs may be received by the antenna 234, processed by a demodulator 232, detected by a MIMO detector 236, if applicable, and further processed by a receive processor 238 to obtain decoded data and control information sent by the UE 120. The receive processor 238 may provide the decoded data to a data sink 239 and the decoded control information to a controller / processor 240. The base station 110 may include a communication unit 244 and may communicate with the network controller 130 via the communication unit 244. The base station 110 may include a scheduler 246 to schedule the UE 120 for downlink and / or uplink communication. In some aspects, a modulator and demodulator (e.g., MOD / DEMOD 232) of the base station 110 may be included within a modem of the base station 110. In some aspects, the base station 110 includes a transceiver. The transceiver may include any combination of antennas 234, modulators and / or demodulators 232, MIMO detectors 236, receive processors 238, transmit processors 220, and / or TX MIMO processors 230. The transceiver, via a processor (e.g., controller / processor 240) and memory 242, may be used to implement any aspects of the methods described herein.

[0124] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or any other components of FIG. 2 may implement one or more techniques associated with QCL selection, as described in more detail elsewhere herein. For example, the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or any other components of FIG. 2 may perform or direct the operation of, for example, process 900 of FIG. 9, process 1000 of FIG. 10, process 1100 of FIG. 11, process 1200 of FIG. 12, and / or other processes described herein. The memory 242 and the memory 282 may store data and program codes for the base station 110 and the UE 120, respectively. In some aspects, the memory 242 and / or the memory 282 may include a non-transitory computer-readable storage medium that stores one or more instructions (e.g., code and / or program code) for wireless communication. For example, the one or more instructions, when executed (e.g., immediately or after being compiled, converted, and / or interpreted) by one or more processors of the base station 110 and / or the UE 120, may cause the one or more processors, the UE 120, and / or the base station 110 to perform or direct operations of, for example, process 900 of FIG. 9, process 1000 of FIG. 10, process 1100 of FIG. 11, process 1200 of FIG. 12, and / or other processes as described herein. In some aspects, executing the instructions may include executing the instructions, converting the instructions, compiling the instructions, and / or interpreting the instructions.

[0135] In some aspects, the base station includes means for determining a first spatial QCL property based at least in part on the first set of CORESET, and / or means for determining a second spatial QCL property based at least in part on the second set of CORESET.

[0136] In some aspects, the base station includes means for selecting a CORESET from the first set of CORESETs based at least in part on a prioritization rule, and / or means for identifying the remainder of the CORESETs from the first set of CORESETs based at least in part on the remainder of the CORESETs having the same spatial QCL properties as the selected CORESET.

[0137] In some aspects, the base station includes means for selecting, from the plurality of CORESETs based at least in part on a prioritization rule, a first set of CORESETs, the first set of CORESETs including a particular CORESET having a PDCCH repetition linked with another PDCCH repetition in another CORESET that at least partially overlaps with the first CORESET, based at least in part on a PDCCH repetition, and / or means for selecting a second set of CORESETs to include another CORESET.

[0138] In some aspects, the base station includes means for selecting a first set of CORESETs to include a first CORESET based at least in part on a first CORESET that includes a first PDCCH repetition, and / or means for selecting a second set of CORESETs to include a second CORESET based at least in part on a second CORESET that includes a second PDCCH repetition.

[0139] In some aspects, the base station includes means for receiving information indicating that the UE is capable of simultaneous communication using at least two spatial QCL properties, the configuration information being based at least in part on the information indicating that the UE is capable of simultaneous communication using the at least two spatial QCL properties.

[0140] In some aspects, the base station includes: means for transmitting, to the UE, configuration information indicating a PDCCH repetition indicative of a link between a first CORESET and a second CORESET, the second CORESET being included among a plurality of CORESETs having at least two different spatial QCL properties associated with overlapping monitoring opportunities; and / or means for transmitting a selected CORESET of the plurality of CORESETs using a selected spatial QCL property corresponding to the selected CORESET, the selected CORESET being selected at least in part based on a prioritization rule that is based at least in part on the link between the first CORESET and the second CORESET. The means for the base station to perform the operations described herein may include, for example, one or more of the transmit processor 220, the TX MIMO processor 230, the modulator 232, the antennas 234, the demodulator 232, the MIMO detector 236, the receive processor 238, the controller / processor 240, the memory 242, or the scheduler 246.

[0141] As noted above, Figure 2 is provided as an example. Other examples may differ from the example described with respect to Figure 2.

[0142] FIG. 3 illustrates an example resource structure 300 for wireless communications in accordance with the present disclosure. The resource structure 300 illustrates an example of various groupings of resources described herein. As shown, the resource structure 300 may include subframes 305. The subframes 305 may include multiple slots 310. Although the resource structure 300 is shown as including two slots per subframe, a different number of slots may be included in a subframe (e.g., four slots, eight slots, 16 slots, 32 slots, or another amount of slots). In some aspects, different types of transmission time intervals (TTIs) other than subframes and / or slots may be used. The slots 310 may include multiple symbols 315, such as 14 symbols per slot.

[0143] A potential control region of a slot 310 may be referred to as a CORESET 320 and may be structured to support efficient use of resources, such as by flexible configuration or reconfiguration of resources in the CORESET 320 for one or more PDCCHs and / or one or more physical downlink shared channels (PDSCHs). In some aspects, the CORESET 320 may occupy the first symbol 315 of the slot 310, the first two symbols 315 of the slot 310, or the first three symbols 315 of the slot 310. Thus, the CORESET 320 may include multiple resource blocks (RBs) in the frequency domain and one, two, or three symbols 315 in the time domain. In 5G, the amount of resources included in the CORESET 320 may be flexibly configured, such as by using radio resource control (RRC) signaling to indicate the frequency domain region (e.g., amount of resource blocks) and / or the time domain region (e.g., amount of symbols) for the CORESET 320.

[0144] As shown, a symbol 315 containing a CORESET 320 may include one or more control channel elements (CCEs) 325 spanning a portion of the system bandwidth, shown as two CCEs 325 as an example. The CCEs 325 may include downlink control information (DCI) used to provide control information for wireless communications. A base station may transmit DCI across multiple CCEs 325 (as shown), where the amount of CCEs 325 used for transmission of the DCI represents the aggregation level (AL) used by the BS for transmission of the DCI. In FIG. 3, an aggregation level of 2 is shown as an example corresponding to two CCEs 325 in the slot 310. In some aspects, a different aggregation level may be used, such as 1, 2, 4, 8, 16, or another aggregation level.

[0145] Each CCE 325 may include a fixed amount of resource element groups (REGs) 330, shown as six REGs 330, or may include a variable amount of REGs 330. In some aspects, the amount of REGs 330 included in a CCE 325 may be specified by a REG bundle size. A REG 330 may include one resource block, and one resource block may include 12 resource elements (REs) 335 within a symbol 315. A resource element 335 may occupy one subcarrier in the frequency domain and one OFDM symbol in the time domain.

[0146] A search space may include all possible locations (e.g., in time and / or frequency) where a PDCCH may be located. CORESET 320 may include one or more search spaces, such as a UE-specific search space, a group common search space, and / or a common search space. A search space may indicate a set of CCE locations where a UE can find a PDCCH that can potentially be used to transmit control information to the UE. The possible locations for the PDCCH may depend on whether the PDCCH is a UE-specific PDCCH (e.g., for a single UE) or a group common PDCCH (e.g., for multiple UEs) and / or the aggregation level used. Possible locations (e.g., in time and / or frequency) for the PDCCH may be referred to as PDCCH candidates, and the set of all possible PDCCH locations at a certain aggregation level may be referred to as a search space. For example, the set of all possible PDCCH locations for a particular UE may be referred to as a UE-specific search space. Similarly, the set of all possible PDCCH locations across all UEs may be referred to as a common search space. The set of all possible PDCCH locations for a particular group of UEs may be referred to as a group common search space. One or more search spaces across an aggregation level may be referred to as a search space (SS) set.

[0147] CORESET 320 may be interleaved or non-interleaved. An interleaved CORESET 320 may have a CCE-REG mapping such that adjacent CCEs are mapped to scattered REG bundles in the frequency domain (e.g., adjacent CCEs are not mapped to consecutive REG bundles in CORESET 320). A non-interleaved CORESET 320 may have a CCE-REG mapping such that all CCEs are mapped to consecutive REG bundles (e.g., in the frequency domain) in CORESET 320.

[0148] As noted above, Figure 3 is provided as an example. Other examples may differ from those described with respect to Figure 3.

[0149] 4 is a diagram illustrating an example 400 of using beams for communication between a base station and a UE in accordance with the present disclosure. As shown in FIG. 4, a base station 110 and a UE 120 may communicate with each other.

[0150] The base station 110 may transmit to a UE 120 located within the coverage area of ​​the base station 110. The base station 110 and the UE 120 may be configured for beamformed communications, where the base station 110 may transmit in the direction of the UE 120 using a directional BS transmit beam, and the UE 120 may receive the transmission using a directional UE receive beam. Each BS transmit beam may have an associated beam ID, beam direction, or beam symbol, among other examples. The base station 110 may transmit downlink communications via one or more BS transmit beams 405.

[0151] The UE 120 may attempt to receive downlink transmissions via one or more UE receive beams 410, which may be configured with different beamforming parameters in the receive circuitry of the UE 120. The UE 120 may identify a particular BS transmit beam 405, denoted as BS transmit beam 405-A, and a particular UE receive beam 410, denoted as UE receive beam 410-A, that provide relatively favorable performance (e.g., have the best channel quality of different measured combinations of the BS transmit beam 405 and the UE receive beam 410). In some examples, the UE 120 may transmit an indication of which BS transmit beam 405 is identified by the UE 120 as a preferred BS transmit beam, and the base station 110 may select the preferred beam for transmission to the UE 120. The UE 120 may thus determine and maintain a beam pair link (BPL) (e.g., a combination of a BS transmitting beam 405-A and a UE receiving beam 410-A) with the base station 110 for downlink communications, and the BPL may be further improved and maintained in accordance with one or more established beam improvement procedures.

[0152] A downlink beam, such as a BS transmit beam 405 or a UE receive beam 410, may be associated with a transmission configuration indication (TCI) state. The TCI state may indicate the directionality or characteristics of the downlink beam, such as one or more QCL properties of the downlink beam. The QCL properties may include, for example, Doppler shift, Doppler spread, mean delay, delay spread, or spatial reception parameters, among other examples. In some examples, each BS transmit beam 405 may be associated with a synchronization signal block (SSB), and the UE 120 may indicate a preferred BS transmit beam 405 by transmitting an uplink transmission within resources of the SSB associated with the preferred BS transmit beam 405. A particular SSB may have an associated TCI state (e.g., for an antenna port or for beamforming). The base station 110 may indicate a downlink BS transmit beam 405 based at least in part on the antenna port QCL properties, which may be indicated by the TCI state, in some examples. The TCI state may be associated with one downlink reference signal set (e.g., SSB and aperiodic, periodic, or semi-persistent channel state information reference signal (CSI-RS)) for different QCL types (e.g., QCL types for different combinations of Doppler shift, Doppler spread, mean delay, delay spread, or spatial reception parameters, among other examples). In cases where the QCL type indicates spatial reception parameters, the QCL type may correspond to analog receive beamforming parameters of the UE receive beam 410 at the UE 120. Thus, the UE 120 may select a corresponding UE receive beam 410 from the set of BPLs based at least in part on the base station 110 indicating the BS transmit beam 405 via the TCI indication.

[0153] The base station 110 may maintain a set of activated TCI states for downlink shared channel transmissions and a set of activated TCI states for downlink control channel transmissions. The set of activated TCI states for downlink shared channel transmissions may correspond to beams that the base station 110 uses for downlink transmissions on a physical downlink shared channel (PDSCH). The set of activated TCI states for downlink control channel communications may correspond to beams that the base station 110 may use for downlink transmissions on a physical downlink control channel (PDCCH) or in a CORESET. The UE 120 may also maintain a set of activated TCI states for receiving downlink shared channel transmissions and CORESET transmissions. When a TCI state is activated for the UE 120, the UE 120 may have one or more antenna configurations based at least in part on the TCI state, and the UE 120 may not need to reconfigure its antennas or antenna weighting configuration. In some examples, the set of activated TCI states (eg, activated PDSCH TCI states and activated CORESET TCI states) for a UE 120 may be configured by a configuration message, such as a radio resource control (RRC) message.

[0154] Similarly, for uplink communications, the UE 120 may transmit in the direction of the base station 110 using a directional UE transmit beam, and the base station 110 may receive the transmission using a directional BS receive beam. Each UE transmit beam may have an associated beam ID, beam direction, or beam symbol, among other examples. The UE 120 may transmit uplink communications via one or more UE transmit beams 415.

[0155] The base station 110 may receive uplink communications via one or more BS receive beams 420. The base station 110 may identify a particular UE transmit beam 415, denoted as a UE transmit beam 415-A, and a particular BS receive beam 420, denoted as a BS receive beam 420-A, that provide relatively favorable performance (e.g., have the best channel quality of different measured combinations of the UE transmit beam 415 and the BS receive beam 420). In some examples, the base station 110 may transmit an indication of which UE transmit beam 415 is identified by the base station 110 as a preferred UE transmit beam, and the base station 110 may select the preferred UE transmit beam for transmission from the UE 120. The UE 120 and the base station 110 may thus obtain and maintain a BPL (e.g., a combination of the UE transmit beam 415-A and the BS receive beam 420-A) for uplink communications, and the BPL may be further improved and maintained according to one or more established beam improvement procedures. An uplink beam, such as a UE transmit beam 415 or a BS receive beam 420, may be associated with a spatial relationship, which may indicate the directionality or characteristics of the uplink beam, similar to one or more QCL properties described above.

[0156] As noted above, Figure 4 is provided as an example. Other examples may differ from those described with respect to Figure 4.

[0157] A base station may transmit a PDCCH to a UE. For example, the base station may transmit the PDCCH in PDCCH candidates. The PDCCH candidates may be included in a search space, which may be included in or associated with a search space set. The UE may attempt to decode the PDCCH (referred to herein as monitoring the PDCCH) in one or more monitoring occasions of the search space set. The one or more monitoring occasions may correspond to one or more PDCCH candidates of the search space set.

[0158] The base station may configure PDCCH repetition to improve the reliability of PDCCH transmission. Each repetition in the PDCCH repetition configuration may be among the PDCCH candidates. Two or more PDCCH candidates may be linked for possible repetition of the same DCI. For example, two PDCCH candidates in different SS sets (associated with corresponding CORESETs) may be linked for PDCCH repetition (e.g., a search space set with index 2 may be linked with a search space set with index 4). If two linked search space sets are associated with different CORESETs, different PDCCH repetitions may use different TCI states, assuming that TCI states are configured and activated per CORESET, thus enabling beam diversity and multiple transmit receive point (multi-TRP) diversity. Each search space set may have different monitoring opportunities (MOs) within a slot and across multiple slots. For PDCCH repetition, the MO of a first search space set may be linked with the MO of a second search space set. The mechanism for linking the MOs of two SS sets may be rule-based or configuration-based (e.g., based at least in part on the parameter searchSpaceLinking). Depending on the search space set configuration (with respect to the MO), the PDCCH repetitions may be time-division multiplexed (PDCCH repetitions occupy different time resources), frequency-division multiplexed (PDCCH repetitions occupy different frequency resources), or both.

[0159] The UE and the base station may communicate with each other using beamformed communications. For example, on the downlink, the base station may transmit a communication using a transmit beam, and the UE may receive the communication using a receive beam. On the uplink, the UE may transmit a communication using a transmit beam, and the base station may receive the communication using a receive beam. As described above, the beam for the communication may be indicated based at least in part on the TCI state, which may indicate a QCL relationship and a source reference signal from which the QCL properties are to be derived. One example of a QCL property is a spatial QCL parameter (e.g., a spatial receive parameter or a spatial transmit parameter), which may be referred to as a QCL Type D or a QCL Type D parameter.

[0160] A UE may be capable of simultaneously receiving a given number of beams. As an example, the UE may be capable of receiving a communication using a single beam at a given time. As another example, the UE may be capable of receiving one or more communications using two or more different beams at a given time. In some cases, a UE may be configured to receive simultaneous communications via more beams than the UE is capable of handling, such as multiple PDCCHs with different QCL properties in a given serving cell or on multiple serving cells on the same frequency band for carrier aggregation (CA) operation. In such cases, the UE may apply prioritization rules to select a CORESET corresponding to a PDCCH among multiple PDCCHs. For example, the UE may select a CORESET and may monitor PDCCHs only in the selected CORESET and any other CORESETs that have the same QCL Type D property as the selected CORESET. In one example, the prioritization rule may be: search space type first (common search spaces have higher priority than UE-specific search spaces), carrier index second (lowest component carrier or serving cell index has highest priority), and search space set index third (lowest search space set index has highest priority).

[0161] In some cases, frequency division multiplexed PDCCH repetitions (or partially overlapping PDCCH repetitions in the time domain) associated with linked SS sets may be transmitted in CORESETs with different TCI states (e.g., different QCL type D properties). In such cases, a baseline QCL prioritization rule (such as a prioritization rule indicating that the PDCCH is monitored only in the selected CORESET and in any other CORESETs with the same QCL type D properties as the selected CORESET) would prevent both PDCCH repetitions from being monitored due to the PDCCH repetitions having different TCI states and overlapping in time, thereby reducing the effectiveness of configuring frequency division multiplexed PDCCH repetitions. Frequency division multiplexed PDCCH repetitions may provide lower latency than time division multiplexed PDCCH repetitions.

[0162] Furthermore, in the case of time-division multiplexed PDCCH repetition when the UE is not able to receive two beams simultaneously, the baseline prioritization rule does not take PDCCH repetition into account when determining the QCL Type D property for PDCCH monitoring. Therefore, the effectiveness of time-division multiplexed PDCCH repetition may be reduced because the UE may not select the QCL Type D property of the first PDCCH repetition and the second PDCCH repetition, meaning that the UE may receive only one (or none) of the first PDCCH repetition and the second PDCCH repetition. Therefore, the effectiveness of PDCCH repetition may be reduced, and the base station communication resources used to configure and implement PDCCH repetition may be consumed with little benefit.

[0163] Some techniques and apparatuses described herein provide a UE capable of supporting multiple TCI states simultaneously to select two or more TCI states for multiple overlapping MOs. For example, if a UE is configured with PDCCH repetition such that a MO of a first linked search space set associated with a first CORESET with a first TCI state overlaps with a MO of a second linked search space set associated with a second CORESET with a second TCI state, the UE may determine two QCL Type-D properties for PDCCH monitoring in overlapping PDCCH monitoring opportunities across multiple CORESETs (within the same component carrier (CC) or in different CCs for intra-band carrier aggregation) if the UE indicates a capability for receiving or using multiple QCL Type-D properties simultaneously. Various techniques described herein provide prioritization rules for selecting QCL Type-D properties. Thus, the use of PDCCH repetition in a frequency division multiplexing scheme, where two or more PDCCH repetitions are associated with different TCI states (and thus different QCL type-D properties), is enabled for UEs that support simultaneous reception using two or more different TCI states. In this way, the latency associated with PDCCH repetition can be reduced and the efficiency of resource usage is improved.

[0164] Some techniques and apparatuses described herein enable a UE to determine QCL Type-D properties (e.g., TCI states) for overlapping PDCCH monitoring opportunities across multiple CORESETs (in the same CC or in different CCs for intra-band CA) based at least in part on a PDCCH repetition configuration linking a first PDCCH repetition in an MO that does not belong to the overlapping PDCCH monitoring opportunity and a second PDCCH repetition in an MO that belongs to the overlapping PDCCH monitoring opportunity. For example, if the MO of the second PDCCH repetition is configured for PDCCH repetition, the UE may prioritize the CORESET associated with the second PDCCH repetition when determining QCL Type-D properties for overlapping PDCCH monitoring opportunities across multiple CORESETs. In some aspects, the above techniques may be implemented in prioritization rules for CORESET selection, as described in more detail elsewhere herein. In this manner, the effectiveness of PDCCH repetition is improved, thereby improving the robustness of PDCCH transmissions and, thereby, improving the use of communication resources for the UE and the base station.

[0165] 5 is a diagram illustrating example signaling 500 associated with receiving a PDCCH using multiple TCI states, in accordance with the present disclosure. As shown, example 500 includes a UE 120 and a BS 110. In some aspects, the BS 110 may be associated with multiple TRPs, multiple remote radio heads, etc.

[0166] As shown in FIG. 5 by reference numeral 510, the UE 120 may transmit capability information. The capability information may indicate one or more capabilities of the UE 120. In example 500, the capability information may indicate the number of supported simultaneous spatial QCL properties for the UE 120. For example, the capability information may indicate that the UE 120 is capable of simultaneous communication using at least two spatial QCL properties. For example, the capability information may indicate the number of QCL Type D properties that the UE 120 can use for simultaneous reception of a communication (e.g., a PDCCH). The terms "spatial QCL property," "QCL Type D property," "QCL property," and "QCL parameter" are used interchangeably herein.

[0167] As indicated by reference numeral 520, the BS 110 may transmit configuration information to the UE 120. For example, the BS 110 may transmit the configuration information via RRC signaling, medium access control (MAC) signaling, DCI, or a combination thereof. The configuration information may configure the UE 120 for PDCCH repetition (e.g., may include a PDCCH repetition configuration). For example, the configuration information may indicate (e.g., based at least in part on the parameter searchSpaceLinking) that a first MO is linked with a second MO for PDCCH repetition, meaning that the first MO may include a first CORESET that includes the first PDCCH repetition and the second MO may include a second CORESET that includes the second PDCCH repetition. In some aspects, the configuration information may link two or more MOs for PDCCH repetition. Additionally or alternatively, the configuration information may link two or more search space sets associated with corresponding CORESETs. The PDCCH repetition may be time division multiplexed, frequency division multiplexed, or a combination thereof. In some aspects, the first CORESET and the second CORESET may at least partially overlap in time. For example, a MO associated with a first linked search space associated with the first CORESET may at least partially overlap in time with a MO associated with a second linked search space associated with the second CORESET.

[0168] The configuration information may also indicate one or more TCI states for the multiple CORESETs. For example, the configuration information may configure a CORESET and indicate a TCI state for the CORESET (which may indicate spatial QCL properties, such as QCL type D properties, and a source reference signal). In some aspects, the first CORESET described above may have a first TCI state, and the second CORESET described above may have a second TCI state that is different from the first TCI state. In some aspects, the one or more TCI states indicated for the multiple CORESETs may be based at least in part on the configuration information. For example, the BS 110 may configure the multiple CORESETs so as not to violate the ability of the UE 120 for simultaneous communication using at least two spatial QCL properties (e.g., at least two different TCI states). As another example, BS110 may configure the PDCCH repetition such that UE120's selection of spatial QCL properties for reception is consistent with the PDCCH repetition (e.g., so that UE120 can receive the first PDCCH repetition and the second PDCCH repetition using the same spatial QCL property, or using at most as many spatial QCL properties as are supported by UE120).

[0169] As indicated by reference numeral 530, UE 120 may select a first set of CORESETs and a second set of CORESETs from the multiple CORESETs configured by the configuration information. For example, in example 500, UE 120 supports simultaneous reception using two TCI states. Thus, UE 120 may select a first set of CORESETs and a second set of CORESETs. The first set of CORESETs may be associated with a first TCI state (e.g., a first spatial QCL parameter), and the second set of CORESETs may be associated with a second TCI state (e.g., a second spatial QCL parameter). In some aspects, at least a portion of the first set of CORESETs may overlap in time with at least a portion of the second set of CORESETs.

[0170] UE 120 may select a first set of CORESETs and a second set of CORESETs based at least in part on the prioritization rule. For example, the prioritization rule may indicate how UE 120 should select a first selected CORESET and a second selected CORESET (which may be different from or the same as the first CORESET and second CORESET described in connection with reference numeral 310) from a plurality of CORESETs. UE 120 may determine a first spatial QCL property (e.g., a QCL type D property) associated with the first selected CORESET based at least in part on a TCI state associated with the first selected CORESET, and may identify the first set of CORESETs based at least in part on each CORESET in the first set of CORESETs being associated with the first spatial QCL property. Similarly, UE 120 may determine a second spatial QCL property associated with the second selected CORESET based at least in part on a TCI state associated with the second selected CORESET, and may identify the second set of CORESETs based at least in part on each CORESET in the second set of CORESETs being associated with a second spatial QCL property.

[0171] The prioritization rule may indicate one or more rules for selecting a CORESET for reception from multiple CORESETs configured for UE 120 using spatial QCL properties associated with the CORESET. In some aspects, the prioritization rule may be defined herein as an “X first, Y second” prioritization rule. X and Y may define a condition for selection of a CORESET. If UE 120 is choosing between a first CORESET and a second CORESET using the “X first, Y second” prioritization rule, UE 120 may first determine whether condition X indicates selecting the first CORESET or the second CORESET. If the first CORESET and the second CORESET are not distinguishable by condition X, UE 120 may next determine whether condition Y indicates selecting the first CORESET or the second CORESET.

[0172] In some aspects, UE 120 may select the first set of CORESETs and the second set of CORESETs regardless of the PDCCH repetition configuration indicated by the configuration information. For example, the prioritization rule may not take the PDCCH repetition configuration into account. In some aspects, the prioritization rule may be a search space type first, a carrier index second, and a search space set index third prioritization rule. For example, UE 120 may first select a CORESET included in a common search space over a CORESET included in a UE-specific search space. If multiple CORESETs are all included in a UE-specific search space or all included in a common search space, UE 120 may select the CORESET with the lowest CC index or lowest serving cell index. If multiple CORESETs are all associated with the same CC index or the same serving cell index, UE 120 may select the CORESET with the lowest SS set index. In this manner, UE 120 may select the first selected CORESET. UE 120 may then determine a first set of CORESETs as all CORESETs associated with the same spatial QCL properties as the first selected CORESET. UE 120 may then determine a second set of CORESETs by applying prioritization rules for the remainder of the CORESETs among the multiple CORESETs other than the first set of CORESETs. Note that the above approaches for selecting the first set of CORESETs and the second set of CORESETs may or may not lead to a CORESET associated with a PDCCH repetition being selected to be included in the first set of CORESETs or the second set of CORESETs. For example, whether one or more overlapping PDCCH repetitions are monitored may depend on spatial QCL parameters of the first set of CORESETs or the second set of CORESETs.

[0173] In some aspects, UE 120 may select the first set of CORESETs and the second set of CORESETs based at least in part on a prioritization rule and a PDCCH repetition configuration. For example, UE 120 may select the first set of CORESETs based at least in part on a prioritization rule in which search space type is first, carrier index is second, and search space set index is third. UE 120 may determine a first spatial QCL property associated with the first set of CORESETs. If there are overlapping PDCCH repetitions (in time) such that there is a first repetition of a PDCCH repetition in the first set of CORESETs (e.g., the first selected CORESET or another CORESET with the same beam if the first repetition is associated with a CORESET with spatial QCL properties), UE 120 may determine a second spatial QCL parameter as the spatial QCL parameter of the CORESET associated with the second repetition. As described above, when there are multiple pairs of first / second repetitions (i.e., when there are multiple CORESETs in the first set of CORESETs, and each CORESET among the multiple CORESETs in the first set of CORESETs is linked to a respective second CORESET (e.g., one CORESET in the first set of CORESETs for each second CORESET)), UE 120 may apply prioritization rules for determining the second spatial QCL property (e.g., based at least in part on the CSS / USS, based at least in part on the search space set index of the first / second PDCCH repetition, based at least in part on the CC index on which the PDCCH repetition is configured, based at least in part on the CORESET identifier of the first / second PDCCH repetition, etc.). For example, the prioritization rules used to select the first set of CORESETs may be referred to as first prioritization rules, and the prioritization rules used to determine the second spatial parameters (and thus to select the second set of CORESETs) may be referred to as second prioritization rules.In some aspects, the second prioritization rule may be a search space type first, a carrier index second, and a search space set index third prioritization rule. In this manner, the UE 120 may select a first set of CORESETs from the plurality of CORESETs based at least in part on the prioritization rule, the first set of CORESETs including a particular CORESET in which a PDCCH repetition is linked with another PDCCH repetition in another CORESET that at least partially overlaps with the first CORESET based at least in part on the PDCCH repetition. The UE 120 may select a second set of CORESETs to include another CORESET. Thus, the UE 120 may take PDCCH repetition into consideration without necessarily selecting a pair of PDCCH repetitions that overlaps with a MO to be monitored.

[0174] In some aspects, UE 120 may select a first set of CORESETs to include a first CORESET associated with a first PDCCH repetition and a second set of CORESETs to include a second CORESET associated with a second PDCCH repetition. For example, UE 120 may select a first set of CORESETs to include a first CORESET based at least in part on a first CORESET including the first PDCCH repetition and at least in part on each CORESET in the first set of CORESETs having the same spatial QCL properties as the first CORESET. UE 120 may select a second set of CORESETs to include a second CORESET based at least in part on a second CORESET including a second PDCCH repetition and / or at least in part on each CORESET in the second set of CORESETs having the same spatial QCL properties as the second CORESET. If multiple pairs of PDCCH repetitions are configured, UE 120 may apply prioritization rules for selecting the first set of CORESETs and / or the second set of CORESETs and / or determining the corresponding spatial QCL properties (e.g., based at least in part on the CSS / USS, based at least in part on the search space set index of the first / second PDCCH repetitions, based at least in part on the CC index for which the PDCCH repetitions are configured, based at least in part on the CORESET identifier of the first / second PDCCH repetitions, etc.). Thus, UE 120 may ensure that at least one pair of PDCCH repetitions with overlapping MOs is monitored.

[0175] 6 is a diagram illustrating an example 600 of determining a first set of CORESETs and a second set of CORESETs in accordance with the present disclosure. Example 600 shows six CORESETs. The spatial QCL parameters of each CORESET are indicated by different types of hatching or filling. Furthermore, CORESET3 is associated with CORESET4 based at least in part on CORESET3 carrying a first PDCCH repetition and CORESET4 carrying a second PDCCH repetition. Also, CORESET5 is associated with CORESET6 based at least in part on CORESET5 carrying a first PDCCH repetition and CORESET6 carrying a second PDCCH repetition.

[0176] CORESET1 carries DCI in the common search space (CSS) set with an index of 2 in CC0. CORESET2 carries DCI in the CSS set with an index of 2 in CC1. CORESET3 carries DCI in the UE-specific search space (USS) set with an index of 1 in CC0. CORESET4 carries DCI in the USS set with an index of 3 in CC0. CORESET5 carries DCI in the USS set with an index of 2 in CC1. CORESET6 carries DCI in the USS set with an index of 3 in CC1.

[0177] If a prioritization rule is applied where search space type is first, carrier index is second, and search space set index is third to select a single spatial QCL property (e.g., corresponding to a single CORESET), the order of selection may be CORESET1, CORESET2, CORESET3, CORESET4, CORESET5, and then CORESET6.

[0178] If a prioritization rule of search space type first, carrier index second, and search space set index third is applied to select a first set of CORESETs and then to select a second set of CORESETs for the remainder of the multiple CORESETs, UE 120 may select CORESET1 as the first selected CORESET. UE 120 may identify CORESET1 and CORESET5 as the first set of CORESETs based at least in part on spatial QCL properties associated with CORESET1 and CORESET5. UE 120 may select CORESET2 as the second selected CORESET from the remaining CORESETs (e.g., CORESET2, CORESET3, CORESET4, CORESET6). UE 120 may identify CORESET2 and CORESET3 as the second set of CORESETs based at least in part on spatial QCL properties associated with CORESET2 and CORESET3. UE 120 may monitor the PDCCH in CORESET1, CORESET2, CORESET3, and CORESET5.

[0179] If a prioritization rule of search space type first, carrier index second, and search space set index third is applied to select a first set of CORESETs, and a second set of CORESETs is selected based at least in part on PDCCH repetition, UE 120 may select CORESET1 as the first selected CORESET. UE 120 may identify CORESET1 and CORESET5 as the first set of CORESETs based at least in part on spatial QCL properties associated with CORESET1 and CORESET5. UE 120 may select CORESET6 as the second selected CORESET based at least in part on CORESET6 being associated with a PDCCH repetition with CORESET5. UE 120 may monitor the PDCCH in CORESET1, CORESET5, and CORESET6.

[0180] If UE 120 selects the first set of CORESETs and the second set of CORESETs based at least in part on the PDCCH repetition, UE 120 may select CORESET3 as the first selected CORESET. Because CORESET3 and CORESET5 are associated with PDCCH repetitions, UE 120 may resolve this ambiguity using a prioritization rule, such as a search space type first, carrier index second, and search space set index third prioritization rule. UE 120 may identify CORESET2 and CORESET3 as the first set of CORESETs based at least in part on the spatial QCL properties associated with CORESET2 and CORESET3. UE 120 may select CORESET4 as the second selected CORESET based at least in part on CORESET3 being associated with a PDCCH repetition with CORESET4. A second set of CORESETs includes only CORESET4, based at least in part on CORESET4 having unique spatial QCL parameters (with respect to the six CORESETs in FIG. 6). UE 120 may monitor the PDCCH in CORESET2, CORESET3, and CORESET4.

[0181] Returning to FIG. 5, as indicated by reference numeral 540, UE 120 may monitor PDCCHs in the first set of CORESETs and the second set of CORESETs. For example, UE 120 may generate a receive beam using the first spatial QCL property and the second spatial QCL property and may monitor MOs corresponding to each CORESET in the first set of CORESETs and the second set of CORESETs. BS 110 may transmit multiple PDCCHs, possibly including one or more PDCCHs in the first set of CORESETs and / or the second set of CORESETs, according to the spatial QCL properties of each of the multiple PDCCHs. In this manner, UE 120 may determine the set of CORESETs to monitor based at least in part on UE 120's capability for simultaneous communication on multiple beams. Thus, frequency division multiplexing PDCCH repetition is improved, thereby reducing latency associated with PDCCH repetition and improving versatility of PDCCH scheduling.

[0182] As noted above, Figures 5 and 6 are given as examples. Other examples may differ from those described with respect to Figures 5 and 6.

[0183] 7 illustrates example signaling 700 associated with determining spatial QCL properties in overlapping PDCCH monitoring opportunities across multiple CORESETs, in accordance with the present disclosure. As shown, example 700 includes a UE 120 and a BS 110. In some aspects, the BS 110 may be associated with multiple TRPs, multiple remote radio heads, etc.

[0184] As shown in FIG. 7 and indicated by reference numeral 710, the BS 110 may transmit configuration information to the UE 120. For example, the BS 110 may transmit the configuration information via RRC signaling, MAC signaling, DCI, or a combination thereof. The configuration information may configure the UE 120 for PDCCH repetition. For example, the configuration information may indicate that a first MO is linked with a second MO for PDCCH repetition, meaning that the first MO may include a first CORESET including the first PDCCH repetition and the second MO may include a second CORESET including the second PDCCH repetition. In some aspects, the configuration information may link two or more MOs for PDCCH repetition. Additionally or alternatively, the configuration information may link two or more search space sets associated with corresponding CORESETs. The PDCCH repetition may be time-division multiplexed, frequency-division multiplexed, or a combination thereof. In some aspects, one of the first and second CORESETs may at least partially overlap with one or more other CORESETs in time, frequency, etc. For example, an MO associated with a first linked search space associated with a first CORESET may at least partially overlap with an MO of another CORESET. In some aspects, the first and second CORESETs may be in the same CC. In some aspects, the first and second CORESETs may be in different CCs (e.g., due to in-band CA).

[0185] As indicated by reference numeral 720, UE 120 may select spatial QCL properties for overlapping PDCCH monitoring opportunities across multiple CORESETs (or may select CORESETs associated with spatial QCL properties) based at least in part on a PDCCH repetition configuration. For example, the PDCCH repetition configuration may link a first PDCCH repetition in an MO that does not belong to the overlapping PDCCH MO with a second PDCCH repetition in an MO that belongs to the overlapping PDCCH MO. UE 120 may select the spatial QCL property based at least in part on a prioritization rule that is based at least in part on a link between the first CORESET and the second CORESET (e.g., between PDCCH repetitions of the first CORESET and the second CORESET, between the first CORESET and the second CORESET MO, etc.). For example, by configuring the MO of the second repetition (included in the second CORESET) for PDCCH repetition, UE 120 may prioritize the CORESET in which the second PDCCH repetition exists when determining spatial QCL properties in overlapping PDCCH monitoring opportunities (that overlap with the second PDCCH repetition) across multiple CORESETs.

[0186] In some aspects, a prioritization rule may prioritize PDCCH repetition linkage over one or more other conditions for selecting a selected CORESET. For example, the prioritization rule may include multiple conditions and may include PDCCH repetition as one of the multiple conditions. By way of example only, the prioritization rule may prioritize search space type first, PDCCH repetition linkage second, carrier index third, and search space set index fourth. In this case, given multiple CORESETs with overlapping MOs, UE 120 may select a CORESET associated with a CSS before selecting any other CORESET. If no CORESET is associated with a CSS, UE 120 may select a CORESET associated with a PDCCH repetition linkage. If no CORESET is associated with a PDCCH repetition linkage, UE 120 may fall back to the third and / or fourth parts of the prioritization rule.

[0187] In some aspects, a prioritization rule may prioritize PDCCH repetition linkage over all other criteria for selecting a selected CORESET. For example, the prioritization rule may be: PDCCH repetition linkage first, search space type second, carrier index third, and search space set index fourth. In this case, given multiple CORESETs with overlapping MOs, UE 120 may select a CORESET associated with a PDCCH repetition linkage before selecting any other CORESETs. If no CORESET is associated with a PDCCH repetition linkage, UE 120 may fall back to the second, third, and / or fourth part of the prioritization rule.

[0188] 8 illustrates an example 800 associated with the signaling described with respect to FIG. 7 according to the present disclosure. Figure 8 illustrates five CORESETs, i.e., four CORESETs associated with the first repetition of a PDCCH repetition configuration and PDCCH candidates in overlapping PDCCH monitoring opportunities in two cells (e.g., CC0 and CC1 in the same band). The spatial QCL parameters of each CORESET are indicated by different types of hatching or filling. Furthermore, CORESET3 is associated with the CORESET carrying the first PDCCH repetition based at least in part on the PDCCH repetition configuration (e.g., based at least in part on the configuration information indicated by reference numeral 710).

[0189] As shown, CORESET1 carries DCI in the CSS set with an index of 2 in CC0. CORESET2 carries DCI in the CSS set with an index of 2 in CC1. CORESET3 carries DCI in the USS set with an index of 1 in CC0. CORESET4 carries DCI in the USS set with an index of 1 in CC1.

[0190] If a prioritization rule of search space type first, carrier index second, and search space set index third is applied to select a single spatial QCL property (e.g., corresponding to a single CORESET), the order of selection may be CORESET1, CORESET2, CORESET3, and then CORESET4. In this case, by not taking the PDCCH repetition configuration into consideration, UE 120 may therefore not monitor the second repetition of the PDCCH repetition configuration in CORESET3.

[0191] If the prioritization rule takes into account the PDCCH repetition configuration (e.g., more than one or more other conditions, or more than all other conditions), UE 120 may select CORESET3 as the selected CORESET (e.g., may determine a spatial QCL parameter corresponding to CORESET3). Thus, UE 120 may select CORESET2 and CORESET3 as a second set of CORESETs for PDCCH monitoring.

[0192] Returning to FIG. 7 , as indicated by reference numeral 730, UE 120 may monitor a PDCCH using a selected spatial QCL property corresponding to the selected CORESET. For example, UE 120 may generate a receive beam using the selected spatial QCL property and monitor the PDCCH based at least in part on the receive beam. BS 110 may transmit multiple PDCCHs, potentially including PDCCHs in the selected CORESET, according to the spatial QCL properties of each of the multiple PDCCHs. In this manner, compatibility with PDCCH repetition configurations is improved, and the likelihood of monitoring PDCCH repetition is improved, thereby improving the efficiency of network resource usage and the robustness of PDCCH communications.

[0193] As noted above, Figures 7 and 8 are given as examples. Other examples may differ from those described with respect to Figures 7 and 8.

[0194] 9 illustrates an example process 900, performed by, for example, a UE, in accordance with the present disclosure. The example process 900 is an example in which a UE (e.g., UE 120) performs operations associated with QCL prioritization rules for control channel repetition.

[0195] As shown in FIG. 9, in some aspects, process 900 may include receiving configuration information indicating a first PDCCH repetition for a first CORESET having a first TCI state and a second PDCCH repetition for a second CORESET having a second TCI state, wherein a first monitoring opportunity for a first linked search space set associated with the first CORESET at least partially overlaps in time with a second monitoring opportunity for a second linked search space set associated with the second CORESET (block 910). For example, a UE may receive (e.g., using the receiving component 1302 shown in FIG. 13 ) configuration information indicating a first PDCCH repetition for a first CORESET having a first TCI state and a second PDCCH repetition for a second CORESET having a second TCI state, as described above, wherein a first monitoring opportunity for a first linked search space set associated with the first CORESET at least partially overlaps in time with a second monitoring opportunity for a second linked search space set associated with the second CORESET.

[0196] 9, in some aspects, process 900 may include monitoring PDCCHs for a first set of CORESET and a second set of CORESET that at least partially overlap in time with each other based at least in part on the configuration information, where the PDCCH monitoring for the first set of CORESET is based at least in part on a first spatial QCL property and the PDCCH monitoring for the second set of CORESET is based at least in part on a second spatial QCL property that is different from the first spatial QCL property (block 920). For example, a UE (e.g., using the monitoring component 1308 shown in FIG. 13) may monitor PDCCHs for the first set of CORESET and the second set of CORESET that at least partially overlap in time with each other based at least in part on the configuration information, as described above, where the PDCCH monitoring for the first set of CORESET is based at least in part on the first spatial QCL property and the PDCCH monitoring for the second set of CORESET is based at least in part on a second spatial QCL property that is different from the first spatial QCL property.

[0197] Process 900 may include additional aspects, such as any single aspect or any combination of aspects described below and / or with respect to one or more other processes described elsewhere herein.

[0198] In a first aspect, the process 900 includes selecting a first set of CORESETs from a plurality of CORESETs based at least in part on a prioritization rule, and selecting a second set of CORESETs from the plurality of CORESETs excluding the first set of CORESETs based at least in part on the prioritization rule.

[0199] In a second aspect, alone or in combination with the first aspect, the prioritization rule is search space type first, carrier index second, and search space set index third.

[0201] In a fourth aspect, alone or in combination with one or more of the first through third aspects, selecting the first set of CORESETs further includes selecting a CORESET from the first set of CORESETs based at least in part on a prioritization rule, and identifying the remainder of the CORESETs from the first set of CORESETs based at least in part on the remainder of the CORESETs having the same spatial QCL properties as the selected CORESET.

[0203] In a sixth aspect, alone or in combination with one or more of the first through fifth aspects, the prioritization rule is a first prioritization rule, the first set of CORESETs includes a plurality of CORESETs linked with other CORESETs, and the selection of the second set of CORESETs is based at least in part on the second prioritization rule.

[0204] In a seventh aspect, alone or in combination with one or more of the first through sixth aspects, the process 900 includes selecting a first set of CORESETs to include a first CORESET based at least in part on a first CORESET that includes a first PDCCH repetition, and selecting a second set of CORESETs to include a second CORESET based at least in part on a second CORESET that includes a second PDCCH repetition.

[0205] In an eighth aspect, alone or in combination with one or more of the first to seventh aspects, selecting the first set of CORESETs and the second set of CORESETs is based at least in part on a prioritization rule for the first CORESET including a first PDCCH repetition and the second CORESET including a second PDCCH repetition.

[0206] In a ninth aspect, alone or in combination with one or more of the first to eighth aspects, the UE is capable of simultaneous communication using at least two spatial QCL properties, and performing PDCCH monitoring for the first set of CORESET and the second set of CORESET is based at least in part on the UE being capable of simultaneous communication using the at least two spatial QCL properties.

[0207] In a tenth aspect, alone or in combination with one or more of the first through ninth aspects, the process 900 includes transmitting information indicating that the UE is capable of simultaneous communication using at least two spatial QCL properties, and the configuration information is based at least in part on the information indicating that the UE is capable of simultaneous communication using the at least two spatial QCL properties.

[0208] 9 illustrates example blocks of process 900, in some aspects process 900 may include additional, fewer, different, or differently ordered blocks compared to the blocks illustrated in FIG 9. Additionally or alternatively, two or more of the blocks of process 900 may be performed in parallel.

[0209] 10 illustrates an example process 1000, performed by, for example, a UE, in accordance with the present disclosure. The example process 1000 is an example in which a UE (e.g., UE 120) performs operations associated with a technique for pseudo-co-location prioritization rules.

[0210] 10 , in some aspects, process 1000 may include receiving configuration information indicating a PDCCH repetition indicating a link between a first CORESET and a second CORESET, the second CORESET being included among a plurality of CORESETs having at least two different spatial QCL properties associated with overlapping monitoring opportunities (block 1010). For example, a UE (e.g., using receiving component 1302 shown in FIG. 13 ) may receive configuration information indicating a PDCCH repetition indicating a link between a first CORESET and a second CORESET, the second CORESET being included among a plurality of CORESETs having at least two different spatial QCL properties associated with overlapping monitoring opportunities, as described above.

[0211] 10 , in some aspects, the process 1000 may include monitoring a PDCCH using selected spatial QCL properties corresponding to a selected CORESET of the plurality of CORESETs, the selected CORESET being selected based at least in part on a prioritization rule based at least in part on a link between the first CORESET and the second CORESET (block 1020). For example, the UE (e.g., using the monitoring component 1308 shown in FIG. 13 ) may monitor a PDCCH (e.g., monitor PDCCH candidates, monitor for PDCCH transmissions, etc.) using selected spatial QCL properties corresponding to a selected CORESET of the plurality of CORESETs, as described above, the selected CORESET being selected based at least in part on a prioritization rule based at least in part on a link between the first CORESET and the second CORESET.

[0212] Process 1000 may include additional aspects, such as any single aspect or any combination of aspects described below and / or with respect to one or more other processes described elsewhere herein.

[0213] In a first aspect, the prioritization rules prioritize PDCCH repetition linkage over one or more other parameters for the selection of the selected CORESET.

[0214] In a second aspect, alone or in combination with the first aspect, the selected CORESET is a second CORESET.

[0215] In a third aspect, alone or in combination with one or more of the first and second aspects, the prioritization rule prioritizes PDCCH repetition linkage over one or more other parameters for selection of the selected CORESET based at least in part on a monitoring opportunity for the second CORESET being associated with a link between the first CORESET and the second CORESET.

[0216] In a fourth aspect, alone or in combination with one or more of the first to third aspects, the prioritization rule prioritizes PDCCH repetition linkage over all other parameters for the selection of the selected CORESET.

[0217] In a fifth aspect, alone or in combination with one or more of the first to fourth aspects, the prioritization rule is: PDCCH repetition linkage first, search space type second, carrier index third, and search space set index fourth.

[0218] In a sixth aspect, alone or in combination with one or more of the first to fifth aspects, the prioritization rule is: search space type first, PDCCH repetition linkage second, carrier index third, and search space set index fourth.

[0219] In a seventh aspect, alone or in combination with one or more of the first through sixth aspects, the first CORESET is in a monitoring opportunity that does not overlap with an overlapping monitoring opportunity.

[0220] In an eighth aspect, alone or in combination with one or more of the first to seventh aspects, at least two CORESETS of the plurality of CORESETS are on different component carriers.

[0221] In a ninth aspect, alone or in combination with one or more of the first to eighth aspects, the multiple CORESETs are on a single component carrier.

[0222] 10 illustrates example blocks of process 1000, in some aspects process 1000 may include additional, fewer, different, or differently ordered blocks compared to the blocks illustrated in FIG 10. Additionally or alternatively, two or more of the blocks of process 1000 may be performed in parallel.

[0223] 11 illustrates an example process 1100 implemented, for example, by a base station, in accordance with the present disclosure. The example process 1100 is an example in which a base station (e.g., base station 110) implements operations associated with techniques for QCL prioritization.

[0224] As shown in FIG. 11, in some aspects, process 1100 may include transmitting configuration information to a UE indicating a first PDCCH repetition for a first CORESET having a first TCI state and a second PDCCH repetition for a second CORESET having a second TCI state, wherein a first monitoring opportunity for a first linked search space set associated with the first CORESET at least partially overlaps in time with a second monitoring opportunity for a second linked search space set associated with the second CORESET (block 1110). For example, a base station (e.g., using the transmission component 1404 shown in FIG. 14 ) may transmit configuration information to a UE indicating a first PDCCH repetition for a first CORESET having a first TCI state and a second PDCCH repetition for a second CORESET having a second TCI state, as described above, wherein a first monitoring opportunity for a first linked search space set associated with the first CORESET at least partially overlaps in time with a second monitoring opportunity for a second linked search space set associated with the second CORESET.

[0225] 11 , in some aspects, process 1100 may include transmitting a first set of CORESETs and a second set of CORESETs that at least partially overlap in time with each other, where the first set of CORESETs is based at least in part on a first spatial QCL property and the second set of CORESETs is based at least in part on a second spatial QCL property that is different from the first spatial QCL property (block 1120). For example, a base station (e.g., using the transmitting component 1404 shown in FIG. 14 ) may transmit a first set of CORESETs and a second set of CORESETs that at least partially overlap in time with each other, as described above, where the first set of CORESETs is based at least in part on a first spatial QCL property and the second set of CORESETs is based at least in part on a second spatial QCL property that is different from the first spatial QCL property.

[0226] Process 1100 may include additional aspects, such as any single aspect or any combination of aspects described below and / or with respect to one or more other processes described elsewhere herein.

[0227] In a first aspect, the process 1100 includes selecting a first set of CORESETs from a plurality of CORESETs based at least in part on a prioritization rule, and selecting a second set of CORESETs from the plurality of CORESETs excluding the first set of CORESETs based at least in part on the prioritization rule.

[0228] In a second aspect, alone or in combination with the first aspect, the prioritization rule is search space type first, carrier index second, and search space set index third.

[0229] In a third aspect, alone or in combination with one or more of the first and second aspects, the process 1100 includes determining a first spatial QCL property based at least in part on a first set of CORESETs, and determining a second spatial QCL property based at least in part on a second set of CORESETs.

[0230] In a fourth aspect, alone or in combination with one or more of the first through third aspects, selecting the first set of CORESETs further includes selecting a CORESET from the first set of CORESETs based at least in part on a prioritization rule, and identifying the remainder of the CORESETs from the first set of CORESETs based at least in part on the remainder of the CORESETs having the same spatial QCL properties as the selected CORESET.

[0231] In a fifth aspect, alone or in combination with one or more of the first to fourth aspects, the process 1100 includes selecting a first set of CORESETs from a plurality of CORESETs based at least in part on a prioritization rule, the first set of CORESETs including a particular CORESET having a PDCCH repetition that is linked with another PDCCH repetition in another CORESET that at least partially overlaps with the first CORESET based at least in part on a PDCCH repetition; and selecting a second set of CORESETs to include another CORESET.

[0232] In a sixth aspect, alone or in combination with one or more of the first through fifth aspects, the prioritization rule is a first prioritization rule, the first set of CORESETs includes a plurality of CORESETs linked with other CORESETs, and the selection of the second set of CORESETs is based at least in part on the second prioritization rule.
