Abstract

A method of wireless communication performed by a user equipment (UE) includes receiving a message indicating a plurality of control resource sets (CORESETs). Each of the plurality of CORESETs includes one or more quasi-co-located (QCL) Type-D properties and is associated with a respective physical downlink control (PDCCH) monitoring occasion that overlaps the PDCCH monitoring occasion. One or more respective PDCCH candidates correspond to the respective PDCCH monitoring occasion. The method also includes receiving a plurality of simultaneous beams including a plurality of PDCCH candidates on one or more component carriers (CCs) operating on a same frequency band. The method further includes monitoring a set of PDCCH candidates of the plurality of PDCCH candidates, the plurality of PDCCH candidates including a first CORESET of the plurality of CORESETs including a first QCL Type-D property, a second CORESET of the plurality of CORESETs associated with a second QCL Type-D property, and a set of monitoring CORESETs of the plurality of CORESETs. Each monitoring CORESET associated with one or both of the first QCL Type-D property or the second QCL Type-D property is based on a number of QCL Type-D properties of the respective monitoring CORESET. In some examples, the first CORESET is a highest priority CORESET based on a set of priority rules.

[0003] open field

[0004] Various aspects of this disclosure generally relate to wireless communications, and more particularly to quasi-coexistence (QCL) priority ordering rules for multiple transmission configuration indicator (TCI) state control resource sets (CORESET).

[0005] background

[0006] Wireless communication systems are widely deployed to provide a variety of telecommunications services such as telephone, video, data, messaging, and broadcasting. Typical wireless communication systems employ multiple access technologies that can support communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power). 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 an enhancement set of the Universal Mobile Telecommunications System (UMTS) mobile standard issued by the 3rd Generation Partnership Project (3GPP). Narrowband (NB) Internet of Things (IoT) and enhanced machine-type communications (eMTC) are enhancement sets of LTE for machine-type communications.

[0007] A wireless communication network may include several base stations (BSs) capable of supporting communication between several user equipments (UEs). UEs can communicate with the base stations (BSs) via downlinks and uplinks. A downlink (or forward link) refers to the communication link from the BS to the UE, while an uplink (or reverse link) refers to the communication link from the UE to the BS. As will be described in more detail, a BS may be referred to as a B-node, evolved B-node (eNB), gNB, access point (AP), radio headend, transmit / receive point (TRP), new radio (NR) BS, 5G B-node, etc.

[0008] The above multiple access technologies have been adopted in various telecommunications standards to provide a common protocol that enables different user equipment to communicate at the city, country, region, and even global levels. New Radio (NR) (also known as 5G) is an enhancement set to the LTE mobile standard issued by the 3rd Generation Partnership Project (3GPP). NR is designed to better support mobile broadband Internet access by using Orthogonal Frequency Division Multiplexing (OFDM) with a Cyclic Prefix (CP) on the downlink (DL), CP-OFDM and / or SC-FDM (e.g., also known as Discrete Fourier Transform Extended OFDM (DFT-s-OFDM)) on the uplink (UL), and supporting beamforming, multiple-input multiple-output (MIMO) antenna technologies and carrier aggregation to improve spectral efficiency, reduce costs, improve service, utilize new spectrum, and better integrate with other open standards.

[0009] The User Equipment (UE) may be unaware of the Physical Downlink Control Channel (PDCCH) aggregation level or the existence of multiple PDCCHs in a subframe or time slot. Therefore, the UE can perform blind decoding of various decoding candidates. UE-specific Search Spaces (USS) and Shared Search Spaces (CSS) can reduce the number of blind decodings. Each PDCCH search space candidate (such as a CSS candidate or a USS candidate) can be associated with a Transport Configuration Indicator (TCI) state. The TCI state indicates the Quasi-Coexistence (QCL) information of the Demodulation Reference Signal (DMRS) used for the PDCCH search space candidate, such as QCL type and time-frequency resources. The Control Resource Set (CORESET) can configure DMRS parameters for the PDCCH search space candidate, such as frequency and time-domain resources and scrambling sequence identity. In some scenarios, the UE can identify multiple PDCCH candidates during overlapping PDCCH monitoring across multiple CORESETs. The UE can attempt to decode one or more PDCCH candidates based on this priority rule.

[0034] Detailed description

[0035] The various aspects of this disclosure are described more fully below with reference to the accompanying drawings. However, this disclosure may be implemented in many different forms and should not be construed as being limited to any specific structure or function given throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of this disclosure to those skilled in the art. Based on these teachings, those skilled in the art will appreciate that the scope of this disclosure is intended to cover any aspect of the disclosure described herein, whether implemented independently of or in combination with any other aspect of this disclosure. For example, any number of the aspects set forth may be used to implement an apparatus or method of practice. Furthermore, the scope of this disclosure is intended to cover such apparatus or methods practiced using additional structures, functionalities, or structures and functionalities that complement or supplement the various aspects of this disclosure set forth. It should be understood that any aspect of this disclosure disclosed may be implemented by one or more elements of the claims.

[0036] Several aspects of a telecommunications system will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and explained in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively, "elements"). These elements can be implemented using hardware, software, or a combination thereof. Whether such elements are implemented in hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0037] It should be noted that while the aspects may be described using terms commonly associated with 5G and next-generation wireless technologies, the aspects of this disclosure may be applied in communication systems based on other generations, such as and including 3G and / or 4G technologies.

[0038] Various aspects of this invention generally relate to techniques and apparatus for selecting physical downlink control channel (PDCCH) candidates according to priority rules when one or more control resource sets (CORESETs) are associated with two quasi-coexistence (QCL) type D attributes. In some examples, a base station may configure user equipment (UE) to have more than one search space (SS) set, such that the number of PDCCH candidates can vary across time slots. In this example, the UE may identify multiple PDCCH candidates during overlapping PDCCH monitoring across multiple CORESETs, where one or more CORESETs may be associated with two QCL type D attributes.

[0039] In some examples, the UE is configured to receive two beams simultaneously from one or more component carriers (CCs). In such examples, the UE generates a priority ranking list of CORESETs from multiple CORESETs based on a set of priority rules. The UE can select the highest priority CORESET from the priority ranking list as the first CORESET. The UE can also select the first QCL type D attribute of the first CORESET as the first surveillance QCL type D attribute, and can select the second QCL type D attribute of the second CORESET from the priority ranking list as the second surveillance QCL type D attribute. The UE can also identify a set of surveillance CORESETs from the priority ranking list, where each surveillance CORESET includes several QCL type D attributes based on the corresponding surveillance COREST, including the same QCL type D attribute as one or both of the first and second surveillance QCL type D attributes. The UE can select a set of PDCCH candidates from multiple PDCCH candidates based on the first and second surveillance QCL type D attributes. In such examples, the PDCCH candidate set may correspond to a first CORESET, a second CORESET, and a monitored CORESET set. The UE can monitor this PDCCH candidate set.

[0040] In other examples, the UE is not configured to receive two beams simultaneously. In such examples, the UE selects a first highest priority CORESET from multiple CORESETs as the first CORESET based on a set of priority rules. The first CORESET may occupy a first symbol set. The UE may determine a QCL type D attribute for each symbol in the first symbol set. Additionally, the UE may remove a first CORESET set from the multiple CORESETs, wherein each CORESET in the first CORESET set occupies a symbol that overlaps with a symbol in the first symbol set, and the overlapping symbol is associated with a different QCL type D attribute. The UE may also identify a first remaining CORESET among the multiple CORESETs in response to the removal of the first CORESET set. The UE may also identify a second CORESET set from these first remaining CORESETs. In such examples, each CORESET in the second CORESET set occupies a symbol that overlaps with a symbol in the first symbol set, and these overlapping symbols may be associated with the same QCL type D attribute. The UE may monitor the PDCCH candidates for the first and second CORESET sets.

[0041] Specific aspects of the subject matter described in this disclosure can be implemented to achieve one or more of the following potential advantages. In some aspects, the UE can use the described techniques to monitor PDCCH candidates based on a priority ranking list of CORESETs associated with one or two QCL Type D attributes. Monitoring PDCCH candidates based on the priority ranking list of CORESETs reduces the number of PDCCH candidates monitored by the UE and also reduces the amount of blind decoding performed by the UE, thereby increasing resources at the UE. Additionally, the described techniques can prepare the UE to use a CORESET with two Transport Configuration Indicator (TCI) states, as proposed for 3GPP Release 17 and later.

[0042] Figure 1 This is a diagram illustrating a network 100 in which various aspects of this disclosure can be practiced. Network 100 can be a 5G or NR network or some other wireless network, such as an LTE network. Wireless network 100 may include several BS 110s (shown as BS110a, BS 110b, BS 110c, and BS 110d) and other network entities. A BS is an entity that communicates with a user equipment (UE) and may also be referred to as a base station, NR BS, B-node, gNB, 5G B-node (NB), access point, transmit / receive point (TRP), etc. Each BS can provide communication coverage for a specific geographic area. In 3GPP, the term "cell" can refer to the coverage area of ​​a BS and / or the BS subsystem serving that coverage area, depending on the context in which the term is used.

[0043] A BS can provide communication coverage for macrocells, picocells, femtocells, and / or another type of cell. Macrocells can cover a relatively large geographic area (e.g., a radius of several kilometers) and allow unrestricted access by UEs with a service subscription. Picocells can cover a relatively small geographic area and allow unrestricted access by UEs with a service subscription. Femtocells can cover a relatively small geographic area (e.g., a residential area) and allow restricted access by UEs associated with that femtocell (e.g., UEs in a Closed Subscriber Group (CSG)). A BS used for macrocells may be referred to as a macro BS. A BS used for picocells may be referred to as a pico BS. A BS used for femtocells may be referred to as a femto BS or a home BS. Figure 1 In the example shown, BS 110a can be a macro BS for macro cell 102a, BS 110b can be a pico BS for pico cell 102b, and BS 110c can be a femto BS for femto cell 102c. A BS can support one or more (e.g., three) cells. The terms “eNB,” “base station,” “NR BS,” “gNB,” “TRP,” “AP,” “B node (NB),” “5G NB,” and “cell” are used interchangeably.

[0044] In some respects, the cell may not be stationary, and the geographical area of ​​the cell may move depending on the location of the mobile BS. In some respects, BSs may interconnect with each other and / or interconnect to one or more other BSs or network nodes (not shown) in the wireless network 100 using any suitable transport network through various types of backhaul interfaces (such as direct physical connections, virtual networks, etc.).

[0045] The wireless network 100 may also include relay stations. A relay station is an entity capable of receiving data transmissions from an upstream station (e.g., a BS or a UE) and transmitting those data transmissions to a downstream station (e.g., a UE or a BS). A relay station may also be a UE capable of relaying transmissions for other UEs. Figure 1 In the example shown, relay station 110d can communicate with macro BS 110a and UE 120d to facilitate communication between BS 110a and UE 120d. A relay station may also be referred to as a relay BS, relay base station, relay, etc.

[0046] Wireless network 100 can be a heterogeneous network comprising different types of Base Stations (BSs) (e.g., 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 effects on interference in wireless network 100. For example, macro BSs may have high transmit power levels (e.g., 5 to 40 watts), while pico BSs, femto BSs, and relay BSs may have lower transmit power levels (e.g., 0.1 to 2 watts).

[0047] As an example, BS 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and core network 130 may exchange communication via backhaul link 132 (e.g., S1, etc.). Base station 110 may communicate with each other directly or indirectly (e.g., via core network 130) on other backhaul links (e.g., X2, etc.).

[0048] Core network 130 may be an evolved packet core (EPC), which may include at least one mobility management entity (MME), at least one serving gateway (S-GW), and at least one packet data network (PDN) gateway (P-GW). The MME may be the control node that handles signaling between UE 120 and the EPC. All user IP packets can be transmitted through the S-GW, which itself can connect to the P-GW. The P-GW provides IP address allocation and other functions. The P-GW can connect to the network operator's IP services. The operator's IP services may include the Internet, intranet, IP Multimedia Subsystem (IMS), and packet switching (PS) streaming services.

[0049] Core network 130 provides user authentication, access authorization, tracking, IP connectivity, and other access, routing, or mobility functions. One or more of base stations 110 or access node controllers (ANCs) can interface with core network 130 via backhaul links 132 (e.g., S1, S2, etc.) and can perform radio configuration and scheduling for communication with UE 120. In some configurations, the various functions of each access network entity or base station 110 can be distributed across various network devices (e.g., radio headends and access network controllers) or combined into a single network device (e.g., base station 110).

[0050] UE 120 (e.g., 120a, 120b, 120c) may be distributed throughout the wireless network 100, and each UE may be stationary or mobile. UE may also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, etc. UE may be a cellular phone (e.g., a smartphone), personal digital assistant (PDA), wireless modem, wireless communication device, handheld device, laptop computer, cordless phone, wireless local loop (WLL) station, tablet, camera, gaming device, netbook, smartbook, ultrabook, medical device or equipment, biometric sensor / device, wearable device (smartwatch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet)), entertainment device (e.g., music or video device, or satellite radio), vehicle component or sensor, smart meter / sensor, industrial manufacturing equipment, GPS device, or any other suitable device configured to communicate via wireless or wired media.

[0051] One or more UEs 120 can establish Protocol Data Unit (PDU) sessions for network slicing. In some cases, UE 120 can select network slices based on application or subscription services. By serving different network slices for different applications or subscriptions, UE 120 can improve its resource utilization in the wireless network 100 while also meeting the performance specifications of individual applications of UE 120. In some cases, the network slice used by UE 120 may be provided by an AMF (Application-Specific Component) associated with one or both of base station 110 and core network 130. Figure 1 (Not shown in the image) to provide services. In addition, session management for network slices can be performed by the Access and Mobility Management Function (AMF).

[0052] UE 120 may include QCL module 140. For the sake of brevity, only one UE 120d is shown as including QCL module 140. In one implementation, QCL module 140 may identify multiple PDCCH candidates in overlapping PDCCH monitoring times across multiple CORESETs, wherein one or more CORESETs may be associated with a single QCL type D attribute or two QCL type D attributes.

[0053] In some examples, QCL module 140 can generate a priority ranking list of CORESETs from multiple CORESETs based on one or more priority rules. QCL module 140 can select a first highest priority CORESET from the priority ranking list as the first CORESET. QCL module 140 can also select a first QCL type D attribute of the first CORESET as the first monitoring QCL type D attribute, and can select a second QCL type D attribute of a second CORESET from the priority ranking list as the second monitoring QCL type D attribute. QCL module 140 can also identify a set of monitoring CORESETs from the priority ranking list, where each monitoring CORESET includes several QCL type D attributes based on the corresponding monitoring COREST, including the same QCL type D attribute as one or both of the first and second monitoring QCL type D attributes. QCL module 140 can select a set of PDCCH candidates from multiple PDCCH candidates based on the first and second monitoring QCL type D attributes. In such examples, the PDCCH candidate set may correspond to a first CORESET, a second CORESET, and a monitored CORESET set. The QCL module 140 can monitor the PDCCH candidate set.

[0054] In other examples, QCL module 140 may select a first highest priority CoreSET from a plurality of CoreSETs as the first CoreSET according to one or more priority rules. The first CoreSET may occupy a first symbol set. QCL module 140 may determine a QCL type D attribute for each symbol in the first symbol set. Additionally, QCL module 140 may remove a first CoreSET set from the plurality of CoreSETs, wherein each CoreSET in the first CoreSET set occupies symbols that overlap with one symbol in the first symbol set, and these overlapping symbols are associated with different QCL type D attributes. QCL module 140 may also identify a first remaining CoreSET among the plurality of CoreSETs in response to the removal of the first CoreSET set. QCL module 140 may also identify a second CoreSET set from these first remaining CoreSETs. In such examples, each CoreSET in the second CoreSET set occupies symbols that overlap with one symbol in the first symbol set, and these overlapping symbols may be associated with the same QCL type D attribute. QCL module 140 can monitor PDCCH candidates for the first CORESET and the second CORESET sets.

[0055] Some UEs can be considered Machine-Type Communication (MTC) UEs, or evolved or enhanced Machine-Type Communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, location tags, etc., which can communicate with a base station, another device (e.g., a remote device), or some other entity. Wireless nodes can provide connectivity to or to a network (e.g., a wide area network such as the Internet) or a cellular network, for example, via wired or wireless communication links. Some UEs can be considered Internet of Things (IoT) devices, and / or can be implemented as NB-IoT (Narrowband Internet of Things) devices. Some UEs can be considered Customer Premises Equipment (CPE). UE 120 can be included inside a housing that houses the components of UE 120, such as processor components, memory components, etc.

[0056] Generally, any number of wireless networks can be deployed in a given geographical area. Each wireless network can support a specific Radio Access Technology (RAT) and can 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 can support a single RAT in a given geographical area to avoid interference between wireless networks using different RATs. In some cases, NR or 5GRAT networks can be deployed.

[0057] In some respects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using base station 110 as an intermediary). For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, etc.), mesh networks, etc. In this scenario, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere as being performed by base station 110. For example, base station 110 may configure UE 120 via downlink control information (DCI), radio resource control (RRC) signaling, media access control-control element (MAC-CE), or via system information (e.g., system information block (SIB)).

[0058] Figure 2 A block diagram of a design 200 for base station 110 and UE 120 is shown. Base station 110 and UE 120 can be Figure 1One of the base stations and one of the UEs. Base station 110 may be equipped with T antennas 234a to 234t, and UE 120 may be equipped with R antennas 252a to 252r, wherein generally T ≥ 1 and R ≥ 1.

[0059] At base station 110, transmit processor 220 can receive data destined for one or more UEs from data source 212, select one or more modulation and coding schemes (MCS) for each UE based at least in part on the Channel Quality Indicator (CQI) received from each UE, process (e.g., encode and modulate) the data for each UE based at least in part on the MCS selected for each UE, and provide data symbols for all UEs. Reducing the MCS decreases throughput but improves transmission reliability. Transmit processor 220 can also process system information (e.g., semi-static resource partitioning information (SRPI) and other information) and control information (e.g., CQI requests, grants, upper-layer signaling, etc.) and provide overhead symbols and control symbols. Transmit processor 220 can also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS)) and synchronization signals (e.g., primary synchronization signal (PSS) and secondary synchronization signal (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 can perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols where applicable, and can... T Each output symbol stream is provided to T Modulators (MODs) 232a-232t. Each modulator 232 can process its own output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator 232 can further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. T downlink signals from modulators 232a to 232t can be transmitted via T antennas 234a to 234t respectively. According to the aspects described in more detail below, position coding can be used to generate synchronization signals to convey additional information.

[0060] At UE 120, antennas 252a to 252r can receive downlink signals from base station 110 and / or other base stations and can provide the received signals to demodulators (DEMODs) 254a to 254r respectively. Each demodulator 254 can condition (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain an input sample. Each demodulator 254 can further process the input sample (e.g., for OFDM, etc.) to obtain received symbols. MIMO detector 256 can obtain the received symbols from all R demodulators 254a to 254r, perform MIMO detection on these received symbols where applicable, and provide detected symbols. Receiver processor 258 can process (e.g., demodulate and decode) these detected symbols, provide the decoded data for UE 120 to data sink 260, and provide the decoded control information and system information to controller / processor 280. The channel processor can determine the Reference Received Power (RSRP), Received Signal Strength Indicator (RSSI), Reference Received Quality (RSRQ), Channel Quality Indicator (CQI), and so on. In some respects, one or more components of the UE 120 may be included in the housing.

[0061] On the uplink, at UE 120, transmit processor 264 can receive and process data from data source 262 and control information from controller / processor 280 (e.g., reports including RSRP, RSSI, RSRQ, CQI, etc.). Transmit processor 264 can also generate reference symbols for one or more reference signals. Symbols from transmit processor 264 can be pre-encoded by TX MIMO processor 266 where applicable, further processed by modulators 254a to 254r (e.g., for Discrete Fourier Transform Extended OFDM (DFT-s-OFDM), CP-OFDM, etc.), and transmitted to base station 110. At base station 110, uplink signals from UE 120 and other UEs can be received by antenna 234, processed by demodulator 254, detected by MIMO detector 236 where applicable, and further processed by receive processor 238 to obtain decoded data and control information transmitted by UE 120. The receiver processor 238 can provide decoded data to the data sink 239 and decoded control information to the controller / processor 240. The base station 110 may include a communication unit 244 and communicate with the core network 130 via the communication unit 244. The core network 130 may include a communication unit 294, a controller / processor 290, and a memory 292.

[0062] The controller / processor 240 of base station 110, the controller / processor 280 of UE 120, and / or Figure 2Any other component may perform one or more techniques associated with selecting PDCCH candidates for monitoring based on priority rules, as described in more detail elsewhere. For example, the controller / processor 240 of base station 110, the controller / processor 280 of UE 120, and / or Figure 2 Any other component of (such as) can execute or direct, for example Figure 8 and 9 The operation of the process and / or other processes as described. Memory 242 and 282 may store data and program code for base station 110 and UE 120, respectively. Scheduler 246 may schedule the UE for data transmission on the downlink and / or uplink.

[0063] The UE may be unaware of the PDCCH aggregation level or the existence of multiple PDCCHs in a subframe or time slot. Therefore, the UE can perform blind decoding of various decoding candidates. UE-specific search spaces (USS) and shared search spaces (CSS) can reduce the number of blind decodings. Each PDCCH search space candidate (such as a CSS candidate or a USS candidate) can be associated with a TCI state. The TCI state indicates QCL information for the demodulation reference signal (DMRS) used for the PDCCH search space candidate, such as QCL type and time-frequency resources. Examples of QCL types may include one or more of Doppler shift (QCL types A and B), Doppler spread (QCL types A, B, and C), average delay (QCL type A), delay spread (QCL types A, B, and C), and spatial reception (RX) parameters (QCL type D). The control resource set (CORESET) can configure parameters for the DMRS of the PDCCH search space candidate, such as frequency and time-domain resources and scrambling sequence identity.

[0064] In some scenarios, a UE can identify multiple PDCCH candidates during overlapping PDCCH monitoring across multiple CORESETs. A conventional UE may not be able to simultaneously receive multiple beams using carrier clustering operations in a given serving cell or on multiple serving cells in the same frequency band, such as two beams with different QCL type D attributes. Therefore, a conventional UE determines the CORESET based on priority rules and monitors PDCCH candidates in the selected CORESET, as well as other CORESETs with the same QCL type D attributes as the selected CORESET. Prioritization rules may first prioritize CSS CORESETs over USS CORESETs. Additionally, priority rules may sort CSSCORESETs and USS CORESETs in ascending order based on the serving cell index and subsequently on the SS set index.

[0065] In 3GPP Release 17 and later, a CORESET can be associated with two TCI states, which may result in the CORESET including two QCL type D attributes. The two TCI states of the CORESET can be applied in Time Division Multiplexing (TDM), Frequency Division Multiplexing (FDM), or Space Division Multiplexing (SDM) modes. In some examples, when the UE is configured to receive two beams simultaneously, the UE can monitor multiple FDM or SDM PDCCH candidates during the monitoring period. In another example, when the UE is configured to receive only one beam during a symbol period, the UE can monitor multiple TDM PDCCH candidates during the monitoring period.

[0066] In one configuration, the UE is configured to receive simultaneous beams from the same component carrier or different component carriers operating in the same frequency band. In this configuration, the PDCCH candidate can be SDM or FDM. Figure 3 This is a diagram illustrating example 300 of multiple PDCCH candidates with overlapping PDCCH monitoring opportunities according to various aspects of this disclosure. Figure 3 In the examples, each of the multiple CORESETs (as shown in CORESET 1-6) can correspond to multiple PDCCH candidates in overlapping PDCCH monitoring moments in two cells (CC0 and CC1 in the same frequency band), and each CORESET has one or two QCL type D attributes. For example, in Figure 3 In the first CORESET (CORESET 1), there is a QCL type D property (x). Furthermore, in Figure 3 In the example, the second CORESET (CORESET 2) includes two QCL type D properties (x, y).

[0067] In one implementation, the UE generates a priority-ordered list of CORESETs from multiple CORESETs based on priority rules. Figure 3 In the example, CORESET prioritizes data according to priority rules. As described, priority rules can be based on SS type, serving cell index, and SS set index. Figure 3 In the example, CSS CORESETs (CORESET 1 and CORESET 2) take precedence over USS CORESETs (CORESET 3-6). After prioritizing based on SS, CORESETs are then prioritized in ascending order based on the serving cell index. Figure 3 As shown, the serving cell index (CC 0) of CORESET 1 is lower than the serving cell index (CC 1) of CORESET 2. Similarly, as... Figure 3 As shown, the serving cell index (CC 0) of CORESET 3-4 is lower than the serving cell index (CC1) of CORESET 5-6. Finally, CORESETs are prioritized in ascending order based on the SS collection index. Figure 3 In the example, the SS set index (1) of CORESET 3 is less than the SS set index (3) of CORESET 4. Similarly, as Figure 3 As shown, the SS set index (2) of CORESET 5 is less than the SS set index (3) of CORESET 6.

[0068] After prioritizing the CORESETs, the UE selects a CORESET from the priority list. The UE can select the first QCL type D attribute of the first CORESET as the first surveillance QCL type D attribute. The UE can then select the second QCL type D attribute from the priority list of the second CORESET as the second surveillance QCL type D attribute. After determining the first and second surveillance QCL type D attributes, the UE identifies the surveillance CORESET set from the priority list of the CORESETs. Each surveillance CORESET in the surveillance CORESET set is associated with several QCL type D attributes based on that surveillance CORESET, along with a QCL type D attribute that is the same as one or both of the first and second surveillance QCL type D attributes. The UE can then monitor the PDCCH candidate set corresponding to the first CORESET, the second CORESET, and the surveillance CORESET set.

[0069] In one implementation, when identifying a surveillance CORESET set, the UE excludes the first and second CORESETs from the CORESET priority ranking list. After excluding the first and second CORESETs, the UE can then identify the first CORESET set from the CORESET priority ranking list. Each CORESET in the first CORESET set is associated with a QCL type D attribute, and this QCL type D attribute is the same as the first surveillance QCL type D attribute or the second surveillance QCL type D attribute. Furthermore, the UE can identify the second CORESET set from the priority ranking list. Each CORESET in the second CORESET set is associated with two QCL type D attributes. In this implementation, the primary QCL type D attribute of each CORESET in the second CORESET set is the same as the first surveillance QCL type D attribute. Similarly, the secondary QCL type D attribute of each CORESET in the second CORESET set is the same as the second surveillance QCL type D attribute. The surveillance CORESET set includes the first and second CORESET sets described above.

[0070] In one configuration, the UE selects the CORESET with the highest priority, such as... Figure 3 CORESET 1. In this configuration, if the selected CORESET has two active TCI states (e.g., the CORESET is associated with two QCL type D attributes), the primary QCL type D attribute is the first monitored QCL type D attribute, and the secondary QCL type D attribute is the second monitored QCL type D attribute. In this configuration, the selected CORESET is both the first and second CORESET. Figure 3 In the example, CORESET 1 is not associated with either of the two QCL type D attributes. Therefore, CORESET 1 can be the first CORESET, and the UE can choose the second CORESET.

[0071] In the current configuration, if the selected CORESET has an active TCI state (e.g., the CORESET is associated with a QCL type D attribute), the UE selects a second QCL type D attribute from the priority ranking list. That is, the selected CORESET is the first CORESET, and one QCL type D attribute of the first CORESET is the first surveillance QCL type D attribute. Additionally, after selecting the first CORESET, the UE excludes the first CORESET set from the priority ranking list of CORESETs. Each CORESET in the first CORESET set is associated with a QCL type D attribute, one of which is equal to the first surveillance QCL type D attribute. Furthermore, the UE can exclude the second CORESET set from the priority ranking list of CORESETs. In this example, each CORESET in the second CORESET set can be associated with two QCL type D attributes, and each of the two QCL type D attributes is different from the first surveillance QCL type D attribute. In this configuration, the UE selects the second CORESET from the priority ranking list of CORESETs after excluding the first and second CORESET sets. The second CORESET can be the highest priority CORESET among the remaining CORESETs in the priority sorting list. In one implementation, the UE can determine that the priority sorting list of CORESETs is empty after excluding the first and second CORESET sets. In this implementation, the second CORESET is the highest priority CORESET in the second CORESET set.

[0072] As an example, in Figure 3 In this context, CORESET 1 is selected as the first CORESET because it has the highest priority. Similarly, CORESET 1 is associated with a QCL type D attribute (x), making QCL type D attribute (x) the first monitored QCL type D attribute. Additionally, because CORESET 1 is associated with a QCL type D attribute, the UE selects the second CORESET. Figure 3 In the example, no CORESET includes two QCL type D properties where both of their QCL type D properties are different from those of CORESET 1. Therefore, CORESET 2 is the second CORESET because CORESET has the next highest priority. In this example, the first monitored QCL type D property is (x), while the second monitored QCL type D property is (y). Additionally, in this example, the monitored CORESET set includes CORESET 5.

[0073] In another aspect of this disclosure, if the first CORESET is associated with two QCL type D attributes, only the primary QCL type D attribute is considered. Therefore, in this configuration, one QCL type D attribute or the primary QCL type D attribute of the first CORESET is the first surveillance QCL type D attribute. In this configuration, after selecting the first CORESET, the UE excludes the first CORESET set from the priority ranking list of CORESETs. Each CORESET in the first CORESET set is associated with one QCL type D attribute, where one QCL type D attribute is equal to the first surveillance QCL type D attribute. Furthermore, the UE may exclude the second CORESET set from the priority ranking list of CORESETs. In this example, each CORESET in the second CORESET set may be associated with two QCL type D attributes, and each primary QCL type D attribute of these two QCL type D attributes is the same as the first surveillance QCL type D attribute. In this configuration, the UE selects the second CORESET from the priority ranking list of CORESETs after excluding the first and second CORESET sets.

[0074] Figure 3 Examples of the current aspect are provided. In these examples, the UE selects CORESET 1 as the first CORESET and selects QCL type D attribute (x) as the first surveillance QCL type D attribute. After selecting the first CORESET, the UE excludes CORESET 2 because the primary QCL type D attribute (x) of CORESET 2 is the same as the first surveillance QCL type D attribute. Therefore, the UE selects CORESET 3 as the second CORESET, where the QCL type D attribute (z) is the second surveillance QCL type D attribute. Furthermore, CORESET 4 and 6 can be included in the surveillance CORESET set based on the fact that CORESET 4 and 6 are associated with the same QCL type D attribute as one or both of the first and second surveillance QCL type D attributes.

[0075] In another aspect of this disclosure, the UE can exclude all CORESETs having two QCL type D attributes. That is, the UE can exclude a first set of CORESETs from the priority ranking list of CORESETs. In this example, each CORESET in the first set of CORESETs may be associated with two QCL type D attributes. After excluding the first set of CORESETs, the UE selects a first CORESET. The first CORESET may be the highest priority CORESET remaining in the priority ranking list. In this aspect, one QCL type D attribute of the first CORESET is a first surveillance QCL type D attribute. In this configuration, after selecting the first CORESET, the UE excludes a second set of CORESETs from the priority ranking list of CORESETs. Each CORESET in the second set of CORESETs is associated with a QCL type D attribute, one of which is equal to the first surveillance QCL type D attribute. Finally, in this aspect, the UE selects a second CORESET from the priority ranking list of CORESETs after excluding the first and second sets of CORESETs. The second CORESET may be the highest priority CORESET remaining in the priority ranking list of CORESETs.

[0076] As Figure 3 In this example, the UE can first exclude CORESET 2 and 4 because both CORESET 2 and 4 are associated with two QCL type D attributes. In this example, after excluding CORESET 2 and 4, the UE selects CORESET 1 as the first CORESET and selects QCL type D attribute (x) as the first surveillance QCL type D attribute. After selecting the first CORESET, the UE selects CORESET 3 as the second CORESET and selects QCL type D attribute (z) as the second surveillance QCL type D attribute. Furthermore, CORESET 4 and 6 can be included in the surveillance CORESET set because they are associated with the same QCL type D attribute as one or both of the first and second surveillance QCL type D attributes.

[0077] In another aspect of this disclosure, the UE determines that one or more of a plurality of cores are associated with two QCL type D attributes. In response to this determination, the UE excludes each core associated with one QCL type D attribute from the plurality of cores. After excluding each core, the UE generates a priority ranking list of cores. In this aspect, the core with the highest priority in the priority ranking list is selected as the first core and the second core. The UE monitors the PDCCH in the first and second cores, as well as in any other core (including cores associated with one QCL type D attribute) that have the same one or two QCL type D attributes as the determined core.

[0078] exist Figure 3 In the example, the UE can determine that CORESET 2 and 4 include two QCL type D attributes. Therefore, the UE can exclude CORESETs associated with one QCL type D attribute (e.g., CORESET 1, 3, 5, and 6). The UE can then select CORESET 2 as the first and second CORESETs, where the QCL type D attribute (x) is the first surveillance QCL type D attribute, and the QCL type D attribute (y) is the second surveillance QCL type D attribute. Furthermore, CORESET 1 and 5 can be included in the surveillance CORESET set based on the fact that CORESET 1 and 5 are associated with the same QCL type D attribute as one or both of the first and second surveillance QCL type D attributes.

[0079] As described, in some configurations, the second coreset is the highest priority coreset remaining in the coreset priority sorting list. In another configuration, priority can be determined based on the first coreset. For example, if the first coreset corresponds to the CSS, then the second coreset should correspond to the USS. As another example, if the first coreset is in the first serving cell, then the second coreset should correspond to another serving cell, such as the second serving cell.

[0080] As described above, the UE identifies the surveillance CORESET set based on a first surveillance QCL type D attribute and a second surveillance QCL type D attribute. In one configuration, if a CORESET is associated with two QCL type D attributes, and one of these two QCL type D attributes is different from either the first or second surveillance QCL type D attribute, the UE excludes that CORESET from the surveillance CORESET set. In another configuration, a CORESET in the surveillance CORESET set may be associated with two QCL type D attributes, and one of these two QCL type D attributes may be different from either the first or second surveillance QCL type D attribute. In this configuration, the UE does not monitor PDCCH candidates in QCL type D attributes of the CORESET that are different from either the first or second surveillance QCL type D attribute. Furthermore, in this configuration, the UE may monitor PDCCH candidates in QCL type D attributes of the CORESET that are the same as either the first or second surveillance QCL type D attribute.

[0081] In another aspect of this disclosure, the UE can be configured to process a single beam in the received symbols. In this aspect, each PDCCH candidate can be TDM. Figure 4A This is a diagram illustrating examples of multiple PDCCH candidates during overlapping PDCCH monitoring, according to various aspects of this disclosure. In some examples, such as Figure 4A As shown, each of the multiple CORESETs (such as CORESET 1-6) can correspond to one or two PDCCH candidates during the PDCCH monitoring period, based on whether the CORESET includes one or two QCL type D attributes. For example, in Figure 4A In this context, the first CORESET (CORESET 1) comprises two QCL type D attributes (x and y) that are TDMed on two symbols. In this respect, each QCL type D attribute of the CORESET may occupy one or more symbols, such as one, two, or three symbols. However, the two or more QCL type D attributes of the CORESET do not occupy the same symbol.

[0082] Figure 4B This is a diagram illustrating examples of selecting a PDCCH candidate from multiple PDCCH candidates during overlapping PDCCH monitoring, according to various aspects of this disclosure. In some examples, such as Figure 4BAs shown, at time t1, the UE selects the highest priority CORESET from multiple CORESETs as the first CORESET according to priority rules. In these examples, it is assumed that the CORESETs (CORESET 1-6) are ordered by priority. Therefore, the UE selects CORESET 1 as the first CORESET, where the first CORESET occupies symbol set 400. The UE can determine the QCL type D attribute for each symbol in the first symbol set. In these examples, the first symbol in symbol set 400 is associated with the QCL type D attribute (x), while the second symbol in the first symbol set 400 is associated with the QCL type D attribute (y).

[0083] After determining the QCL type D attribute, in one configuration, the UE removes a first CORESET set from multiple CORESETs. Each CORESET in the first CORESET set occupies one or more symbols associated with a QCL type D attribute that differs from the QCL type D attribute of overlapping symbols in the same symbol set 400. For example, in Figure 4B At time t2, CORESET 2, 4 and 5 can be removed because each of CORESET 2, 4 and 5 occupies a symbol that includes a QCL-Type-D attribute that is different from the overlapping symbols in symbol set 400.

[0084] After excluding the first CORESET set, the UE identifies the second CORESET set from the remaining CORESETs. Each CORESET in the second CORESET set occupies one symbol, which includes the same QCL type D attribute as the overlapping symbols in symbol set 400. PDCCH candidates in the second CORESET set can be monitored. For example, in Figure 4B At time t3, the UE identifies CORESET 3 and 6 as symbols with the same QCL type D attribute as the overlapping symbols in symbol set 400. Therefore, PDCCH candidates for CORESET 3 and 6 can be monitored. That is, in this configuration, the UE monitors the PDCCH candidates for the first CORESET (e.g., CORESET 1) and the second CORESET set (e.g., CORESET 3 and 6).

[0085] In one configuration, the UE identifies a third CORESET set from the second CORESET set that completely overlaps with symbol set 400. For example, in Figure 4B In this example, the symbol associated with CORESET 6 completely overlaps with the second symbol in symbol set 400. As another example, in... Figure 4BIn this configuration, the symbols associated with CORESET 2 do not completely overlap with symbol set 400. That is, the symbols of CORESET 2 include non-overlapping portions. In this configuration, the third CORESET set can be removed based on further considerations. Furthermore, PDCCH candidates in the third CORESET set can be monitored. In this configuration, after removing the third CORESET set, the UE repeats the process from time t1 to t3 until a CORESET is selected for monitoring or excluded.

[0086] In another configuration, the UE identifier has a first CORESET with two QCL type D attributes, such as Figure 4B The UE can determine the QCL type D attribute for each symbol occupied by the first CORESET. After identifying the first CORESET, the UE identifies one or more second CORESETs whose QCL type D attributes are consistent with those of the first CORESET on a symbol-by-symbol basis. That is, the second CORESET does not have symbols with QCL type D attributes that are different from those of the overlapping symbols of the first CORESET. In this configuration, the UE monitors the PDCCH candidates of the first and second CORESETs.

[0087] In one configuration, the per-symbol QCL type D determination can be performed for a UE configured to simultaneously receive two beams. In this configuration, for each symbol in a plurality of CORESETs, the UE determines two distinct QCL type D attributes. That is, the UE can determine a first surveillance QCL type D attribute and a second QCL type D attribute for each symbol. The process for determining the first surveillance QCL type D attribute and the second QCL type D attribute can be based on the above reference. Figure 3 One or more aspects are described. In this configuration, the UE monitors a first CORESET associated with a first monitoring QCL type D attribute, a second CORESET associated with a second monitoring QCL type D attribute, and PDCCH candidates for the monitoring CORESET set. In one configuration, if a CORESET has one or more symbols that include a QCL type D attribute different from the overlapping symbols of the first and second monitoring QCL type D attributes of the first and second CORESETs, then the CORESET is excluded from the monitoring CORESET set. Additionally, if a CORESET occupies one or more symbols, and each symbol has a QCL type D attribute that is the same as the first or second monitoring QCL type D attribute of the overlapping symbols of the first and second CORESETs, then the CORESET is added to the monitoring CORESET set.

[0088] In another aspect of this disclosure, the PDCCH candidates of CORESET associated with two QCL type D attributes can be partially monitored. Figure 5 This is a diagram illustrating an example of partial PDCCH candidate monitoring according to various aspects of this disclosure. Figure 5 In the examples, the second CORESET (CORESET 2) can be associated with two QCL type D attributes (z and y) that are TDMed on the two symbols. The first CORESET (CORESET 1) can be selected for monitoring, such that the first monitoring QCL type D attribute is (x) and the second monitoring QCL type D attribute is (y). In these examples, only one symbol of CORESET 2 has the same QCL type D attribute as the overlapping symbol. That is, as Figure 5 As shown, the second symbols 500 of CORESET 1 and 2 have the same QCL type D attribute (y), while the first symbols 502 of CORESET 1 and 2 have different QCL type D attributes (x and z). In this example, the UE can monitor the PDCCH candidates on the second symbol 500 of CORESET 2 while excluding the PDCH candidates on the first symbol 502 of CORESET 2.
