[0001] Cross-reference to related applications

[0002] This patent application claims priority to U.S. Provisional Patent Application No. 63 / 008,596, filed April 10, 2020, entitled “SPAN-BASED CONTROLCHANNEL FOR MULTIPLE TRANSMIT RECEIVE POINTS,” and U.S. Non-Provisional Patent Application No. 17 / 223,653, filed April 6, 2021, entitled “SPAN-BASED CONTROL CHANNEL FOR MULTIPLE TRANSMIT RECEIVE POINTS,” which are hereby incorporated herein by reference. Technical Field

[0003] This disclosure generally relates to technologies and apparatus for wireless communication and span-based control channels for multiple transmit / receive points (TRPs). Background Technology

[0004] Wireless communication systems are widely deployed to provide various types of telecommunications content, such as voice, 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, 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-CDMA) systems, and Long Term Evolution (LTE). LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard released by the 3rd Generation Partnership Project (3GPP).

[0005] A wireless network may include multiple base stations (BSs) capable of supporting communication for multiple user equipments (UEs). UEs can communicate with the BS via downlinks and uplinks. A downlink (or "forward link") refers to the communication link from the BS to the UE, while an uplink (or "backlink") refers to the communication link from the UE to the BS. As will be described in more detail herein, a BS may be referred to as a Node B, gNB, Access Point (AP), Radio Headend, Transmit / Receive Point (TRP), New Radio (NR) BS, 5G Node B, etc.

[0006] The multiple access technologies mentioned above 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. NR (also known as 5G) is a set of enhancements to the LTE mobile standard released by 3GPP. NR is designed to better support mobile broadband internet access by improving spectrum efficiency, reducing costs, improving service, utilizing new spectrum, and using Orthogonal Frequency Division Multiplexing (OFDM) with a Cyclic Prefix (CP) on the downlink (DL) and CP-OFDM and / or SC-FDM (e.g., also known as Discrete Fourier Transform Extended OFDM (DFT-s-OFDM)) on the uplink (UL) to better integrate with other open standards, as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technologies and carrier aggregation. As the demand for mobile broadband access continues to increase, further improvements to LTE, NR, and other radio access technologies remain useful. Summary of the Invention

[0026] Various aspects of this disclosure are described more fully below with reference to the accompanying drawings. However, this disclosure may be embodied in many different forms and should not be construed as limited to any particular structure or function given throughout this disclosure. Rather, these aspects are provided to make this disclosure comprehensive and complete, and to fully convey the scope of protection of this disclosure to those skilled in the art. Based on the teachings herein, those skilled in the art will recognize that the scope of protection of this disclosure is intended to cover any aspect of this disclosure disclosed herein, whether implemented independently of or in conjunction with any other aspect of this disclosure. For example, any number of aspects set forth herein may be used to implement an apparatus or practice.

It should be understood that any aspect of this disclosure disclosed herein may be embodied by one or more elements of the claims.

[0027] Several aspects of a telecommunications system will now be presented with reference to various devices and technologies. These devices and technologies will be described in detail below and illustrated 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 these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the system as a whole.

[0028] It should be noted that while terms commonly associated with 5G or NR Radio Access Technologies (RATs) may be used in this document to describe aspects, aspects of this disclosure may be applied to other RATs, such as 3G RATs, 4G RATs, and / or RATs after 5G (e.g., 6G).

[0029] Figure 1 This is a schematic diagram illustrating an example of a wireless network 100 according to this disclosure. Wireless network 100 may be or may include elements of a 5G (NR) network and / or an LTE network, etc. Wireless network 100 may include multiple base stations 110 (shown as BS110a, BS110b, BS110c, and BS110d) and 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 / Receive Point (TRP), etc. Each BS may provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may 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.

[0030] A BS can provide communication coverage for macrocells, picocells, femtocells, and / or other cell types. A macrocell can cover a relatively large geographic area (e.g., a radius of several kilometers) and allow unrestricted access for UEs with service subscriptions. A picocell can cover a relatively small geographic area and allow unrestricted access for UEs with service subscriptions. A femtocell can cover a relatively small geographic area (e.g., a home) and allow restricted access for UEs associated with the femtocell (e.g., UEs in a Closed Subscriber Group (CSG)). A BS used for macrocells can be called a macro BS. A BS used for picocells can be called a pico BS. A BS used for femtocells can be called a femto BS or a home BS. Figure 1 In the example shown, BS110a can be a macro BS for macro cell 102a, BS110b can be a pico BS for pico cell 102b, and BS110c 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,” “Node B,” “5G NB,” and “cell” are used interchangeably herein.

[0031] In some respects, the cell may not be fixed, and the geographical area of ​​the cell may move depending on the location of the mobile BS. In some respects, the BS may use any suitable transport network to interconnect with each other and / or with one or more other BSs or network nodes (not shown) in the wireless network 100 via various types of backhaul interfaces (e.g., direct physical connections or virtual networks).

[0032] The wireless network 100 may also include relay stations. A relay station is an entity that receives data transmissions from an upstream station (e.g., a BS or UE) and transmits the data to a downstream station (e.g., a UE or BS). A relay station can also be a UE that can relay transmissions for other UEs. Figure 1 In the example shown, relay BS110d can communicate with macro BS110a and UE 120d to facilitate communication between BS110a and UE 120d. A relay BS can also be referred to as a relay station, relay base station, relay, etc.

[0033] Wireless network 100 can be a heterogeneous network, which includes different types of BSs, such as macro BSs, pico BSs, femto BSs, repeater BSs, etc. These different types of BSs can have different transmit power levels, different coverage areas, and different effects on interference in wireless network 100. For example, macro BSs can have high transmit power levels (e.g., 5 to 40 watts), while pico BSs, femto BSs, and repeater BSs can have lower transmit power levels (e.g., 0.1 to 2 watts).

[0034] Network controller 130 can be coupled to a group of base stations (BSs) and can provide coordination and control for these BSs. Network controller 130 can communicate with the BSs via backhaul. The BSs can also communicate with each other directly or indirectly via wireless or wired backhaul.

[0035] UEs 120 (e.g., 120a, 120b, 120c) may be distributed 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, user 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 computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or apparatus, a biosensor / device, a wireless sensor / device, etc., wearable devices (smartwatches, smart clothing, smart glasses, smart wristbands, smart jewelry (e.g., smart rings, smart bracelets)), entertainment devices (e.g., music or video devices or satellite radio equipment), vehicle components or sensors, smart meters / sensors, industrial manufacturing equipment, GPS devices, or any other suitable device configured to communicate via wireless or wired media.

[0036] Some UEs can be considered Machine-Type Communication (MTC) or Evolved or Enhanced Machine-Type Communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, instruments, monitors, and / or location tags that can communicate with a base station, another device (e.g., a remote device), or some other entity. For example, a wireless node can provide connectivity to 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 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 within a housing that houses the components of UE 120 (e.g., processor components and / or memory components). In some aspects, the processor components and memory components can be coupled together. For example, the processor components (e.g., one or more processors) and memory components (e.g., memory) can be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0037] Generally, any number of wireless networks can be deployed in a given geographical area. Each wireless network can support a specific RAT and can operate on one or more frequencies. A RAT can also be referred to as a radio technology, air interface, etc. A frequency can 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 5G RAT networks can be deployed.

[0038] In some aspects, 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 communication with each other). For example, UEs 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 or vehicle-to-infrastructure (V2I) protocols) and / or mesh networks. In this case, UEs 120 may perform scheduling operations, resource selection operations, and / or other operations performed by base station 110 as described elsewhere herein.

[0039] Devices in the wireless network 100 can communicate using the electromagnetic spectrum, which can be subdivided into various categories, bands, channels, etc., based on frequency or wavelength. For example, devices in the wireless network 100 can communicate using an operating band with a first frequency range (FR1), which can span from 410 MHz to 7.125 GHz, and / or can communicate using an operating band with a second frequency range (FR2), which can span from 24.25 GHz to 52.6 GHz. The 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, although it differs from the ultra-high frequency (EHF) band (30 GHz–300 GHz) designated as "millimeter wave" by the International Telecommunication Union (ITU). Therefore, unless otherwise specified, it should be understood that the terms "sub-6GHz," etc. (if used herein), can broadly refer to frequencies less than 6GHz, frequencies within FR1, and / or intermediate frequency band frequencies (e.g., greater than 7.125GHz). Similarly, unless otherwise specified, it should be understood that the terms "millimeter wave," etc. (if used herein), can broadly refer to frequencies within the EHF band, frequencies within FR2, and / or intermediate frequency band frequencies (e.g., less than 24.25GHz). It is conceivable that the frequencies included in FR1 and FR2 can be modified, and the techniques described herein are applicable to these modified frequency ranges.

[0040] As mentioned above, providing Figure 1 As an example. Other examples may differ from those for... Figure 1 Example of the description.

[0041] Figure 2This is a schematic diagram illustrating an example 200 of a base station 110 communicating with a UE 120 in a wireless network 100 according to the present disclosure. The base station 110 may be equipped with T antennas 234a to 234t, and the UE 120 may be equipped with R antennas 252a to 252r, wherein typically T ≥ 1 and R ≥ 1.

[0042] At base station 110, transmit processor 220 can receive data 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 channel quality indicators (CQI) received from the UE, process (e.g., code and modulate) the data for each UE based at least in part on the selected MCS(s) for the UE, and provide data symbols for all UEs. Transmit processor 220 can also process system information (e.g., semi-static resource allocation information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper-layer signaling), 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) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signal (PSS) or secondary synchronization signal (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 can perform spatial processing (e.g., precoding, if applicable) on data symbols, control symbols, overhead symbols, and / or reference symbols, and can provide T output symbol streams to T modulators (MODs) 232a to 232t. Each modulator 232 can process its corresponding output symbol stream (e.g., for OFDM) 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. The T downlink signals from modulators 232a to 232t can be transmitted via T antennas 234a to 234t, respectively.

[0043] 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 adjust (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) to obtain a received symbol. MIMO detector 256 can obtain the received symbol from all R demodulators 254a to 254r, perform MIMO detection (if applicable) on the received symbol, and provide the detected symbol. Receiver processor 258 can process (e.g., demodulate and decode) the detected symbol, 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 term "controller / processor" can refer to one or more controllers, one or more processors, or a combination thereof. The channel processor can determine the Reference Signal Received Power (RSRP) parameter, the Received Signal Strength Indicator (RSSI) parameter, the Reference Signal Received Quality (RSRQ) parameter, and / or the CQI parameter, as well as other parameters. In some aspects, one or more components of the UE 120 may be included in a housing.

[0044] Network controller 130 may include communication unit 294, controller / processor 290, and memory 292. Network controller 130 may include, for example, one or more devices in a core network. Network controller 130 may communicate with base station 110 via communication unit 294.

[0045] Antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include one or more antenna panels, antenna groups, antenna element sets, and / or antenna arrays, etc., or may be included in one or more antenna panels, antenna groups, antenna element sets, and / or antenna arrays, etc. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include one or more antenna elements. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include sets of coplanar antenna elements and / or sets of non-coplanar antenna elements. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include antenna elements within a single housing and / or antenna elements within multiple housings. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include elements coupled to one or more transmitting and / or receiving components (e.g., antennas 234a to 234t and / or antennas 252a to 252r). Figure 2 One or more antenna elements (one or more components).

[0046] 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, and / or CQI). Transmit processor 264 can also generate reference symbols for one or more reference signals. Symbols from transmit processor 264 can be pre-encoded (if applicable) by TX MIMO processor 266, further processed by modulators 254a to 254r (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to base station 110. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 254) of UE 120 can be included in a modem within UE 120. In some aspects, UE 120 includes a transceiver. The transceiver may include any combination of antenna(s) 252, modulator and / or demodulator 254, MIMO detector 256, receiver processor 258, transmitter processor 264, and / or TX MIMO processor 266. The transceiver may be configured by a processor (e.g., controller / processor 280) and memory 282 to perform aspects of any of the methods described herein (e.g., as referenced). Figure 3-7 (as stated above).

[0047] At base station 110, uplink signals from UE 120 and other UEs can be received by antenna 234, processed by demodulator 232, detected by MIMO detector 236 (if applicable), and further processed by receiver processor 238 to obtain decoded data and control information transmitted by UE 120. Receiver processor 238 can provide the decoded data to data sink 239 and the decoded control information to controller / processor 240. Base station 110 may include communication unit 244 and communicate with network controller 130 via communication unit 244. Base station 110 may include scheduler 246 to schedule UE 120 for downlink and / or uplink communication. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 232) of base station 110 may be included in the modem of base station 110. In some aspects, base station 110 includes a transceiver. The transceiver may include (or include) any combination of antenna(s) 234, modulator and / or demodulator 232, MIMO detector 236, receiver processor 238, transmitter processor 220, and / or TX MIMO processor 230. The transceiver may be configured with a processor (e.g., controller / processor 240) and memory 242 to perform aspects of any of the methods described herein (e.g., as referenced). Figure 3-7 (as stated above).

[0048] The controller / processor 240 of base station 110, the controller / controller 280 of UE 120 and / or Figure 2 Any other component may perform one or more techniques associated with span-based control channels for multiple TRPs, as described in more detail elsewhere herein. For example, the controller / processor 240 of base station 110, the controller / controller 280 of UE 120, and / or Figure 2 Any other component can execute or direct, for example Figure 6 Process 600 Figure 7 The operation of process 700 and / or other processes described herein. Memory 242 and 282 may store data and program code for base station 110 and UE 120, respectively. In some aspects, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, when executed by one or more processors of base station 110 and / or UE 120 (e.g., directly, or after compilation, transformation, and / or interpretation), these one or more instructions may cause one or more processors, UE 120, and / or base station 110 to perform or direct, for example... Figure 6 Process 600 Figure 7 The operation of process 700 and / or other processes described herein. In some aspects, executing instructions may include running the instructions, translating the instructions, compiling the instructions, and / or interpreting the instructions, etc.

[0049] In some aspects, UE 120 may include: a unit for receiving configuration information for a plurality of carriers, wherein a first set of the plurality of carriers is a single-TRP carrier, and a second set of the plurality of carriers is a multi-TRP carrier; a unit for determining, for the plurality of carriers, a distribution satisfying the per-span capability of the UE, wherein the distribution is a distribution of at least one of a plurality of non-overlapping control channel elements (CCEs) or a plurality of blind decoding (BDs), wherein the distribution is at least partially based on which of the plurality of carriers are single-TRP carriers or multi-TRP carriers; and a unit for receiving communication on the plurality of carriers according to the distribution; and / or similar units. In some aspects, the unit may include a combination of Figure 2 One or more components of the described UE 120, such as controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, DEMOD 254, MIMO detector 256, receive processor 258; and / or similar components.

[0050] In some aspects, base station 110 may include: a unit for transmitting configuration information for a plurality of carriers to a UE, wherein a first set of the plurality of carriers is a single-TRP carrier, and a second set of the plurality of carriers is a multi-TRP carrier; a unit for determining, for the plurality of carriers, a distribution satisfying the UE's per-span capability, wherein the distribution is a distribution of at least one of a plurality of non-overlapping CCEs or a plurality of blind decodings, wherein the distribution is at least partially based on which of the plurality of carriers are single-TRP carriers or multi-TRP carriers; and a unit for transmitting communication on the plurality of carriers according to the distribution; and / or similar units. In some aspects, the unit may include a combination of Figure 2 One or more components of the described base station 110, such as antenna 234, DEMOD 232, MIMO detector 236, receive processor 238, controller / processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234; and / or similar components.

[0051] Although Figure 2 The blocks are shown as different components, but the functions described above for these blocks can be implemented in a single hardware, software, or combined component or various combinations of components. For example, the functions described for transmit processor 264, receive processor 258, and / or TX MIMO processor 266 can be executed by controller / processor 280 or executed under the control of controller / processor 280.

[0052] As mentioned above, providing Figure 2 As an example. Other examples may differ from those for... Figure 2 Example of the description.

[0053] In some RATs (e.g., 3GPP Release 15 for 5G / NR), different Physical Downlink Control Channel (PDCCH) monitoring capabilities are defined. As an example, Feature Group (FG) 3-1 (which may be mandatory for Release 15 UEs) can instruct the UE to monitor all PDCCH candidates used for scheduling data within the first few symbols of a time slot. As another example, FG 3-5b (which may be optional for Release 15 UEs) can be defined at least partially based on the concept of spans. A time slot can include multiple spans, and a span can include one or more PDCCH candidates. Different span configurations can be supported. Figure 3 Describe the span configuration in more detail.

[0054] In 5G / NR networks, base stations transmit PDCCH (which may include control information, such as downlink control information (DCI)) at least in part based on search space sets. A given search space set includes candidates that can carry PDCCH within that search space set, where each candidate is associated with one or more CCEs. A CCE may consist of multiple resource element groups (REGs). A REG may include a resource block and an OFDM symbol. One or more search space sets may be associated with a control resource set (CORESET). In 5G / NR networks, base stations can flexibly schedule and transmit PDCCH. In other words, PDCCH transmission in 5G / NR networks is not limited to a specific set of frequency resources and / or time resources in a given radio frame (as is the case in, for example, LTE networks). The frequency and time domain resources of the PDCCH are configured based on each CORESET. Therefore, once a UE is configured with a CORESET, the UE has information identifying which resource blocks in the frequency domain are allocated to the search space set associated with that CORESET, and information identifying the number of consecutive symbols occupied by that search space set.

[0055] To receive a PDCCH associated with one or more candidates of a given UE-specific search space set (where the UE-specific search space set is a search space set that can carry control information specific to one or more particular UEs), the UE can attempt to decode the PDCCH from the candidates in the search space set. For example, the UE can determine one or more CCE indices associated with the candidates and can attempt to decode the PDCCH (e.g., using a blind decoding process). In some cases (e.g., 3GPP Release 15 for 5G / NR), the limit on the number of non-overlapping CCEs and BDs is defined on a per-slot basis. Therefore, it is possible to configure a large number of CCEs / BDs within a span (in extreme cases, all CCEs / BDs). This greatly increases the complexity of the UE, especially when trying to comply with processing schedules applicable to applications supporting Ultra-Reliable Low-Latency Communication (URLLC). On the other hand, if the scheduler chooses to distribute CCEs / BDs across several different spans, the number of CCEs / BDs per span may be insufficient. For example, for a subcarrier spacing (SCS) of 30 kHz and a span capability of (X,Y) = (2,2), each span could have 8 CCEs. Therefore, only one candidate with aggregation level = 8 can be supported. Figure 3 Describe the span capability in more detail.

[0056] To address the aforementioned issues, 3GPP Release 16 for 5G / NR introduced PDCCH monitoring capabilities, which are at least partially based on UE span configuration. To improve scheduling flexibility, the number of non-overlapping CCEs and BDs per time slot has been increased compared to 3GPP Release 15 for 5G / NR. Furthermore, to reduce UE complexity, per-span CCE / BD limits (also known as per-span capabilities) can be specified. This PDCCH monitoring capability with per-span defined CCE / BD limits may be referred to herein as span-based monitoring capability or Release 16 monitoring capability, while per-slot-based PDCCH monitoring capability may be referred to as time-slot-based monitoring capability or Release 15 monitoring capability. In some aspects, Release 16 PDCCH can be used for URLLC service types.

[0057] In some cases, a UE may be configured with more carriers than the threshold identified by its PDCCH monitoring capabilities. For example, if a UE is configured with both version 15 and version 16 PDCCHs on different carriers, and if the number of DL carriers exceeds the UE's monitoring capabilities for version 15 and / or version 16 PDCCHs, the number of non-overlapping CCEs to be received or BDs to be performed may exceed the UE's capabilities on one or more carriers. Therefore, it may be advantageous to allocate CCEs and / or BDs among carriers with different PDCCH monitoring capabilities (e.g., slot-based monitoring capabilities versus span-based monitoring capabilities), different SCSs, and different span capabilities. However, there may be ambiguity regarding how to perform this distribution, especially when the UE is configured with both version 15 and version 16 PDCCHs.

[0058] In some aspects, this distribution can be performed separately for the carrier set associated with version 16 PDCCH and the carrier set associated with version 15 PDCCH. In this case, the UE or BS can determine the number of non-overlapping CCEs or BDs on several carriers for each scheduled cell, for carriers configured with version 15 PDCCH and version 16 PDCCH respectively. For carriers configured with version 15 PDCCH, the value... The number of component carriers (CCs) for which the UE can perform slot-based monitoring can be represented, and the distribution of BD (e.g., denoted by M in the following equation) and non-overlapping CCE (e.g., denoted by C in the following equation) can be determined as follows:

[0059] If the UE is configured with Each downlink cell has a bandwidth portion (BWP) with an SCS configuration μ, where... Therefore, the UE does not need to monitor more than [number] times per time slot for each scheduled cell on the active DL BWP of the scheduling cell. PDCCH candidates or more Non-overlapping CCEs.

[0060] If the UE is configured with There are downlink cells, and the DL BWP has an SCS configuration μ, where,

[0061] If the DL BMP of the activated cell is the active DL BMP of the activated cell, and the DL BMP of the deactivated cell is the DL BMP of the activated cell with an index provided by firstActiveDownlinkBWP-Id, then the UE...

[0062] No need to The active DL BWP of one or more scheduling cells in one or more downlink cells.

[0063] More than 100 monitoring sessions per time slot PDCCH candidates or more Non-overlapping CCEs.

[0064] For each scheduled cell, the UE does not need to monitor more than [number missing] times per slot on the active DL BWP with SCS configuration μ in the scheduled cell. PDCCH candidates or more Non-overlapping CCEs.

[0065] A UE can communicate with multiple TRPs. More generally, a UE can receive a CORESET configuration associated with two or more CORESET configurations (e.g., two or more CORESET pool indices, where each CORESET pool index corresponds to a TRP). A TRP is a communication point associated with a gNB. For example, a gNB can control multiple TRPs and can use multiple TRPs for spatial diversity communication with the UE, or it can use a single TRP to communicate with the UE. However, for UEs capable of using a combination of single-TRP and multi-TRP carriers, there may be ambiguity regarding how CCE and / or BD should be distributed for version 16 carriers (e.g., carriers associated with version 16 PDCCH configurations and span-based monitoring). For example, multi-TRP carriers can utilize more UE resources (e.g., processing resources, reception resources, etc.) than single-TRP carriers. Therefore, challenges may arise regarding how to handle single-TRP and multi-TRP carriers when distributing CCE and / or BD, how to perform span-based overbooking and dropping, etc. If the distribution of CCE and / or BD does not take into account version 16 PDCCH and multi-TRP carriers, a suboptimal CCE / BD distribution may be determined and / or may exceed the UE's capabilities, thereby using computing resources and battery power and reducing throughput.

[0066] Some of the techniques and apparatus described herein provide for determining the distribution of CCE and / or BD on multiple carriers, including at least one multi-TRP carrier. For example, some of the techniques and apparatus described herein perform hard splits between carriers with different subcarrier spacings, between carriers configured with version 15 and version 16 PDCCHs, and between carriers configured with search space sets and / or CORESETs aligned with different span configurations. Single-TRP sets and multi-TRP sets of carriers can then be defined, and CCE / BD allocation can be performed against these carrier sets, thereby enabling compliance with UE capability limitations and improving network performance.

[0067] The techniques and apparatus described herein provide span-based overbooking and drop rules for multi-TRP carriers, thereby implementing overbooking and drop, which improves resource utilization on multi-TRP carriers. Some of the techniques and apparatus described herein provide separate span configurations for each TRP of a multi-TRP carrier, which increases network configuration flexibility and allows services such as URLLC and enhanced mobile broadband (eMBB) to be used on the same carrier. Furthermore, some of the techniques and apparatus described herein provide a process for distributing CCE and / or BD based at least in part on whether the span configurations of multi-TRP carriers are aligned with each other. This improves compliance with UE capability limitations, thereby enhancing network performance.

[0068] It should be noted that the techniques performed for the first and second TRPs of multi-TRP communication described above and elsewhere in this document can be performed for any set of CORESETs that are at least partially distinguishable from each other based on distinguishing parameters. For example, the techniques and apparatus described herein can be performed for carriers associated with CORESETs with two or more different CORESET pool indices, carriers associated with CORESETs with two or more different timing capability indications, carriers associated with two or more configured CORESETs at least partially based on the indicated or configured parameters of the CORESETs, and so on.

[0069] Figure 3 This is a schematic diagram illustrating example 300 of the span in a time slot for monitoring the physical downlink control channel according to this disclosure. Figure 3 A set of time slots associated with each span configuration (as shown by reference numeral 310) is illustrated. The span configuration can identify the minimum gap X and the maximum span duration Y between the starting symbols of two spans.

[0070] The spans corresponding to the span configurations (2,2), (4,3), and (7,3) are indicated by reference numerals 320, 330, and 340, respectively. The spans indicated by reference numeral 320 are represented using alternating diagonal shading lines because these spans are adjacent to each other and would otherwise be difficult to distinguish. The spans indicated by reference numerals 330 and 340 are separated by symbols not included in the span, which are indicated by white rectangles.

[0071] The minimum gaps X for span configurations (2,2), (4,3), and (7,3) are denoted by reference numerals 350, 360, and 370, respectively. It should be noted that X defines the minimum gap; therefore, the starting symbols of a pair of spans associated with span configuration (2,2) may be separated by two or more symbols. Furthermore, the maximum span duration Y defines the maximum span time; therefore, span 330 can have one or two symbol spans while still remaining within the definition of span configuration (4,3).

[0072] Span configurations can be associated with per-span capabilities for the number of Business Targets (BDs) and / or the number of Non-overlapping Component Targets (CCEs) within a span. The per-span capability for the number of BDs can identify the maximum number of BDs that can be configured within spans 320 / 330 / 340, and the per-span capability for the number of Non-overlapping CCEs can identify the maximum number of Non-overlapping CCEs that can be configured within spans 320 / 330 / 340. These per-span capabilities can also be referred to as BD limits and CCE limits, respectively.

[0073] The UE can report its ability to support one or more span configurations. For example, the UE can report that it supports one or more of the span configurations (2,2), (4,3), and (7,3). The UE can determine which span configuration will be used for communication, at least in part, based on the search space configuration. For example, the search space configuration can indicate search space candidates, and the UE can identify the span configurations aligned with the search space candidates. When the search space configuration is aligned with two or more span configurations, the UE can use the maximum CCE limit and / or BD limit associated with the two or more span configurations. The BD limit can identify the number of PDCCH candidates that the UE needs to monitor.

[0074] The UE can use a maximum CCE / BD limit and a maximum total CCE / BD limit to perform the distribution of BD and CCE, as described elsewhere in this document. The maximum CCE / BD limit can identify the maximum number of blind decoding or non-overlapping CCEs per span and per carrier, and the maximum total CCE / BD limit can identify the maximum number of blind decoding or non-overlapping CCEs across several spans on one or more active downlink bandwidth portions of the scheduling cell, assuming span alignment on the scheduling cell. Combined Figure 4 A more detailed description of "alignment" is provided. In some respects, the maximum total CCE limit may be referred to as C_tot or... And the maximum total BD limit can be referred to as M_tot or CCE limits and BD limits can differ for various parameters (e.g., different span configurations, digital schemes, number of TRPs (e.g., single-TRP versus multi-TRP carriers), etc.). The notation used to describe CCE or BD limits can indicate one or more parameters associated with CCE. For example, the maximum total CCE limit for a given subcarrier spacing (SCS, denoted by μ) and a given span configuration can be expressed as... express.

[0075] As mentioned above, providing Figure 3 As an example. Other examples may differ from those for... Figure 3 The situation described.

[0076] Figure 4 This is a schematic diagram illustrating example 400 of span alignment and misalignment based at least in part on whether the search space is configured in the span, according to the present disclosure. Figure 4 The diagram illustrates the span across multiple component carriers (CCs). It should be noted that in this document, "CC" is generally used interchangeably with "cell" and "carrier." A CC is one of several frequency blocks allocated to a user as part of a carrier aggregation (CA) configuration. CA increases data rates by configuring multiple CCs. CCs can be intra-band (e.g., all CCs are included in the same frequency band) or inter-band (e.g., CCs are included in two or more different frequency bands), and can be non-contiguous or contiguous. Figure 4 The span shown uses a (2,2) span configuration in a time slot with a 30kHz SCS. Therefore, in Figure 4 In the diagram, a time slot comprises 14 symbols (not shown), and the span begins every two symbols. Diagonal padding indicates that a search space (SS) is configured across the spans of the CCs. The spans configured with the SS can be referred to as "configured spans". As shown, for CC1 and CC2, all spans are configured, while for CC3, CC4, and CC5, corresponding subsets of spans are configured.

[0077] When two or more CCs have the same SCS and span configuration (e.g., (X,Y)), and the two or more CCs share one or more sets of overlapping configured spans, and each set of overlapping configured spans of the two or more CCs begins with the corresponding same symbol, the two or more CCs are referred to as “aligned”. Reference numeral 410 shows a set of overlapping spans from CC1 to CC5 starting with the same symbol. However, in Example 400, under one definition of “aligned”, CC1 to CC5 are not all aligned with each other because not all configured spans of CC1 to CC5 overlap. For example, while all spans are configured on CC1 and CC2, not all spans are configured on CC3, CC4, and CC5. However, since CC1 and CC2 have the same SCS and span configuration, and since all overlapping configured span pairs of CC1 and CC2 begin with the corresponding same symbol (e.g., symbols 0, 2, 4, 6, 8, 10, and 12, not explicitly shown), CC1 and CC2 are aligned with each other. If each span on each carrier in Example 400 is filled with diagonal padding, then all five CCs will be aligned with each other. Furthermore, CC3 and CC4 are aligned with each other, but not with CC1, CC2, or CC5.

[0078] The maximum total BD and CCE limits for the UE can be observed between spans in each overlapping span group. For example, for the configured span group shown in figure 410, BD and CCE must be limited to both: the maximum CCE / BD limit on a given carrier, and the maximum total CCE / BD limit on CC1 to CC5 in the aggregation.

[0079] As mentioned above, providing Figure 4 As an example. Other examples may differ from those for... Figure 4 The situation described.

[0080] Figure 5 This is a schematic diagram illustrating Example 500 of determining the distribution of CCE and / or BD for a multi-TRP carrier in accordance with this disclosure. As shown, Example 500 includes UE 120 and BS110.

[0081] As shown by reference numeral 510 in the accompanying drawings, UE 120 may signal capability information (e.g., UE capability information) to BS 110. In some aspects, the capability information may include information related to version 16 PDCCH monitoring, such as indicating whether UE 120 can be configured with one or more carriers for version 16 PDCCH monitoring, and / or similar information. In some aspects, the capability information may identify UE 120's CCE limitations and / or BD limitations. In some aspects, the capability information may identify factors associated with multi-TRP communication, such as γ as described elsewhere herein.

[0082] As shown by reference numeral 520 in the attached figure, UE 120 can be configured with multiple carriers. For example, BS 110 can provide UE 120 with configuration information for multiple carriers. In some aspects, the configuration information can indicate whether each of the multiple carriers is associated with a version 15 (e.g., slot-based) PDCCH monitoring configuration or a version 16 (e.g., span-based PDCCH monitoring configuration with CCE / BD limits defined for each span) PDCCH monitoring configuration. In some aspects, the configuration information can indicate distinguishing parameters for CORESET on the multiple carriers (e.g., CORESET pool index, timing capability indicator, and / or other similar parameters). For example, the configuration information can map multiple carriers to spans, at least in part, based on span configurations associated with the multiple carriers. The configuration information can be provided via Radio Resource Control (RRC) signaling, Media Access Control (MAC) signaling, DCI, combinations thereof, etc.

[0083] As shown by reference numeral 530 in the accompanying drawings, BS110 and / or UE 120 may allocate CCE and BD according to various rules described below, at least in part, based on whether a carrier among multiple carriers is a single-TRP carrier or a multi-TRP carrier. In some aspects, UE 120 may determine the distribution of CCE and / or BD and may receive communication on multiple carriers according to said distribution. In some aspects, UE 120 may receive communication on multiple carriers without determining said distribution. For example, BS110 may ensure that the communication and the configuration of the multiple carriers conform to the determined distribution. The determination of said distribution may be performed before or after configuring the multiple carriers.

[0084] The following description describes determining the maximum CCE / BD limit for one or more single-TRP carriers and one or more multi-TRP carriers without considering whether the carrier is a version 16 carrier (e.g., a carrier configured for version 16 PDCCH). After describing the determination of the maximum CCE / BD limit for one or more single-TRP carriers and one or more multi-TRP carriers without considering whether the carrier is a version 16 carrier, a description of determining the maximum CCE / BD limit considering whether the carrier is a version 16 carrier is provided. This represents the number of single-TRP cells associated with a given SCS, and This indicates the number of multi-TRP cells associated with a given SCS. In other words, in the following description, subscript 0 indicates the number, capability, or limitation associated with a single-TRP cell, and subscript 1 indicates the number, performance, or limitation associated with a multi-TRP cell. CORESETPoolIndex is a distinguishing parameter that indicates whether a CORESET is associated with a first group (e.g., the first TRP) or a second group (e.g., the second TRP). In some respects, CORESETPoolIndex can distinguish between more than two CORESET groups. A single-TRP cell can be associated with several CORESETs, all of which are associated with the same CORESETPoolIndex value, while a multi-TRP cell can be associated with several CORESETs associated with two or more different CORESETPoolIndex values.

[0094] - For several CORESETs with the same CORESETPoolIndex value, monitor more than [number missing] per time slot.

[0095] PDCCH candidates or more Non-overlapping CCEs.

[0096] If, for the UE-specific search space (USS) used for scheduling on the primary cell, the UE is not provided with a CORESETPoolIndex for the first CORESET, or is provided with a value of 0 for the first CORESET and a value of 1 for the second CORESET, and if or The procedure can then be used only to identify one or more search spaces to be discarded, applying only to the USS set associated with the first CORESET. The UE does not expect to monitor PDCCH in a USS set that has not been assigned a PDCCH candidate for monitoring.

[0097] The distribution of CCEs and BDs can involve hard splitting and soft splitting. "Hard splitting" refers to dividing multiple carriers into two or more carrier groups, at least in part based on one or more characteristics of the carriers. For example, if a carrier set is hard split based on an SCS, all carriers associated with a first SCS can be placed in a first group, all carriers associated with a second SCS can be placed in a second group, and so on. A carrier group formed by hard splitting multiple carriers can be associated with a set of BDs or CCEs to be distributed among the carriers in that group. "Soft splitting" can be performed within a carrier group formed by hard splitting multiple carriers. For example, the set of CCEs or BDs in a carrier group can be softly split among the carriers in that group, at least in part based on one or more rules as described below.

[0098] In some aspects, UE 120 can distribute non-overlapping CCEs and / or BDs at least in part based on SCS, span configuration, multi-TRP or single-TRP configuration, and whether the carriers are associated with version 16 PDCCH. As an example, UE 120 can hard split multiple carriers based on SCS, whether multiple carriers are associated with version 16 PDCCH, and the alignment of the search space set with the span configuration of the multiple carriers to form carrier groups with the same SCS, version 16 PDCCH configuration (or without version 16 PDCCH configuration), and span configuration alignment. UE 120 can then perform soft splitting to distribute CCEs and BDs between a first set of carriers as single-TRP carriers and a second set of carriers as multi-TRP carriers.

[0099] In some respects, UE 120 can distribute non-overlapping CCEs and / or BDs based at least in part on the rules described above for multi-TRP CCE / BD distribution, while considering whether multiple carriers are associated with version 16 PDCCH configuration. For example, UE 120 can use the rules described above, and can use... to replace And use to replace Therefore, UE 120 can at least partially base its decision on whether the cell is associated with version 16 PDCCH (as indicated by r16 in the variable subscript) and the set of the first carrier (by...). The set of the second carrier (indicator) and the second carrier (by) (Instructions) to perform a hard split. Additionally, if all cells are configured with version 16 PDCCH, UE 120 can use... replace Furthermore, if UE 120 is configured with both version 15 PDCCH carriers and version 16 PDCCH carriers, then use replace In some aspects, UE 120 can perform the distribution across one or more SCSs associated with version 16PDCCH. For example, UE 120 can perform the distribution for SCSs configured with version 16PDCCH. As a more specific example, UE 120 can perform the distribution for SCSs at 15 kHz and 30 kHz (e.g., SCS configurations 0 and 1). Therefore, the summation including SCS configurations 0 to 3 can be replaced with the summation including SCS configurations 0 and 1. Furthermore, per-slot constraints (e.g., the maximum number and / or maximum total number of non-overlapping CCEs / BDs per slot) can be replaced with per-span constraints. Therefore, the equation and The output defines the limits for CCE and BD for the span across different carriers in both aligned and unaligned cases.

[0100] In some aspects, UE 120 or BS110 may perform PDCCH over-schedule and / or drop for multi-TRP carriers. "Over-schedule" refers to the practice of scheduling more PDCCHs than can be transmitted in a given resource set (e.g., a given span). In some aspects, UE 120 may perform span-based over-schedule and drop. In some aspects, span-based over-schedule and / or drop may be permitted only on the primary carrier, in a fixed single subset of spans or a subset of spans where there is a search space set associated with a CORESET with index 0. In some aspects, this limitation may be defined as: a fixed subset of spans with a common search space (CSS) (excluding type 3 CSS) associated with a CORESET having an unconfigured or zero CORESETPoolIndex. In some aspects, this limitation may be defined as: a fixed subset of spans with a CSS associated with an unconfigured or zero CORESETPoolIndex. In some respects, this limitation can be defined as a fixed subset of spans of CSSs that are associated with a CORESET having an unconfigured or zero CORESETPoolIndex, and include only a subset of type 3 CSSs configured to monitor (e.g., group common, format 2-X) DCI formats. Therefore, UE 120 and / or BS 110 can perform span-based over-booking and discarding, which improves resource utilization and conserves computational resources.

[0101] In some aspects, two or more TRPs can be associated with different span configurations. For example, two or more TRPs may serve different service types with different needs, so using different span configurations may be advantageous for such TRPs. In this case, on a given serving cell, the search space / CORESET configuration of the first TRP can be at least partially based on a (2,2) span configuration, and the search space / CORESET configuration of the second TRP can be at least partially based on a (7,3) span configuration. For example, the search space and / or CORESET of the first TRP can be aligned with a (2,2) span, and the search space and / or CORESET of the second TRP can be aligned with a (7,3) span. In some aspects, multiple active BWPs on a given CC can be allowed. For example, two or more BWPs can be associated with different search space configurations corresponding to different span configurations. It should be noted that support for different span configurations is not limited to multi-TRP implementations and can be used for any set of CORESETs associated with a distinguishing parameter, as described below.

[0102] For a carrier associated with a version 16 PDCCH configuration (e.g., a carrier configured with PDCCHMornitoringCapabilityConfig=R16 PDCCH monitoring capability), there are at least three options for configuring the carrier's search space and CORESET:

[0103] Type 1: Configure two different distinguishing parameters for the carrier (e.g., pool index and / or similar parameters), and form a single span set by the search space of CORESET with the same pool index.

[0104] Type 2: Configure two different distinguishing parameters for the carrier (e.g., pool index and / or similar parameters), and form a single span set by the search space of CORESET with different pool indices.

[0105] Type 3: Configure a single distinguishing parameter for the carrier (e.g., pool index and / or similar parameters), and form a single span set by the search space of CORESET.

[0106] Type 1 can correspond to multiple-TRP carriers, where there are two different span configurations for each TRP. Type 2 can correspond to multiple-TRP carriers, where there is a single span configuration for two or more TRPs. Type 3 can correspond to a single-TRP carrier. UE 120 and / or BS110 can count carriers multiple times, at least in part, based on whether the carrier is a Type 1 carrier, a Type 2 carrier, or a Type 3 carrier, and can perform CCE / BD distribution at least in part based on the carrier counts. For example, a Type 1 carrier can be counted twice as a single-TRP carrier: once as having a given SCS and a first span configuration (e.g., (X,Y)). A portion of, and again counted as having a given SCS and a second span configuration (e.g., (X',Y')). Part of it. Type 2 carriers can be counted as multi-TRP carriers. Part of it. Type 3 carriers are counted as single-TRP carriers. Part of it.

[0107] In some respects, CORESET pool indexes (e.g., CORESETPoolIndex) can be used to distinguish between assortments. Figure 5 The CORESET is described. However, in some aspects, any form of distinguishing parameter can be used. For example, distinguishing parameters can be provided using RRC signaling associated with the CORESET or the carrier. More specifically, if a carrier is configured with both minimum processing capabilities 1 and 2, and the timing capability indication is based on the index of the CORESET in which the DCI is detected, then the carrier can be considered a type 1 or type 2 carrier. A carrier with a single processing timeline can be considered a type 3 carrier.

[0108] In some aspects, UE 120 and / or BS110 can distinguish between Type 1 and Type 2 carriers. For example, when two TRPs use the same span configuration, UE 120 can distinguish between the two TRPs at least in part based on a distinguishing parameter. In the first case, if the search space / CORESET configuration of the two TRPs makes all spans formed individually by each search space set perfectly aligned (e.g., if the two TRPs are perfectly aligned with each other), then the carriers associated with these two TRPs can be considered multi-TRP carriers (e.g., Type 2). If the spans are not perfectly aligned, the carriers can be considered single-TRP carriers (e.g., Type 1). In some aspects, parameters (e.g., RRC parameters and / or similar parameters) can be used to distinguish between Type 1 and Type 2 carriers. The counting of carriers based at least in part on the state of a carrier as a Type 1, 2, or 3 carrier can be referred to as the virtual carrier concept.

[0109] As an example, consider 3 versions of 16-carrier:

[0110] ●CC0:SCS=30KHz, (2,2) for TRP 1, (7,3) for TRP 2

[0111] ●CC1:SCS=30KHz and (2,2), only has CORESETPoolIndex 0.

[0112] ●CC2:SCS = 30kHz and (2,2), as a type 1 carrier (with two CORESET pool indices).

[0113] UE 120 and / or BS110 can determine the M_tot and C_tot of the (2,2) carrier:

[0114] ●CC0 can be counted as a single-TRP carrier, once for (2,2) and once for (7,3).

[0115] ●CC1 can be counted as a single-TRP carrier.

[0116] ●CC2 can be counted as a multi-TRP carrier.

[0117] Therefore, for a set of carriers configured with version 16PDCCH, SCS = 30KHz and (2,2) mode, N_DL,0 = 2 and N_DL,1 = 1.

[0118] In some aspects, UE 120 may perform the distribution of BD and / or CCE based at least in part on a factor (e.g., γ) used to scale single-TRP capabilities for multi-TRP carriers. For example, UE 120 or BS110 may multiply the per-span capability for a single-TRP carrier by this factor to determine the per-span capability for a multi-TRP carrier. This factor may be based at least in part on the UE's capabilities. For example, UE 120 may report the factor to BS110, or BS110 may determine the factor at least in part on the UE 120's capabilities (e.g., multi-TRP capabilities and / or similar capabilities).

[0119] In some aspects, the factor and / or per-span capability can be allocated among the two or more carriers, at least in part, based on the configuration of two or more carriers. For example, for each (X,Y) mode (e.g., span configuration), UE120 can determine the per-slot CCE / BD limit as (per-span limit * maximum number of spans per slot). For example, the maximum number of spans per slot is 7 for (2,2), 3 for (4,3), 2 for (7,3), and 4 for (3,2). Now, for a given factor reported by UE 120, BS110 or UE 120 can amplify the per-slot CCE / BD limit for each (X,Y) with a factor of (Z * factor), and then split the result among the spans of (X,Y). For example, consider one CC with (2,2) and (7,3) and Z = 0.5. The total CCE per slot is limited to 112 for both cases, and for this example, the factor is 1.5. The sum per slot for (2,2) is 112 * 1.5 / 2 = 84, resulting in a limit of 84 / 7 per span. The sum per slot for (7,3) is 84, resulting in a limit of 84 / 2 per span. In some respects, setting Z = 0.5 might be appropriate if the slot-level limits are equal for different (X,Y) modes on a given carrier.

[0120] In a more general case, two different scaling factors can be assumed to scale the time slot limit proportionally. For example, consider a single CC with span configurations of (7,3) and (2,2). For this example, the CCE limit per span for (7,3) is 56, and the CCE limit per span for (2,2) is 8. The factor (e.g., γ) reported by UE 120 in this example is 1.5. In this case, the limit per time slot for (7,3) is 112. The proportional limit per time slot for (7,3) equals 1.5 * 112 * 112 / (112 + 56) = 112. Thus, the limit per span is 56. Similarly, the time slot limit for (2,2) is 56. The proportional limit per time slot for (2,2) is 1.5 * 56 * 56 / (112 + 56) = 28. Thus, the limit per span is 8. Note that this method proportionally allocates the factor between different (X,Y) modes (e.g., 1.5 in this case).

[0121] As shown by reference numeral 540 in the attached figure, UE 120 can receive communication on multiple carriers according to the distribution described. For example, UE 120 can receive single-TRP and / or multi-TRP communication on multiple carriers. Single-TRP and / or multi-TRP communication can satisfy the per-span limit of UE 120. Therefore, the allocation efficiency of CCE and / or BD is improved, thereby improving the utilization of multi-TRP and single-TRP carrier resources.

[0122] As mentioned above, providing Figure 5 As an example. Other examples may differ from those for... Figure 5 Example provided.

[0123] It should be noted that any reference to a single-TRP carrier may more generally refer to a carrier associated with a CORESET having a single distinguishing parameter, while any reference to a multi-TRP carrier may more generally refer to a carrier associated with a CORESET having two or more different distinguishing parameters.

[0124] Figure 6 This is a schematic diagram illustrating an exemplary process 600 performed, for example, by a UE according to this disclosure. Exemplary process 600 is an example of an operation performed by a UE (e.g., UE 120, etc.) associated with a span-based control channel for multi-TRP.

[0125] like Figure 6 As shown, in some aspects, process 600 may include: receiving configuration information for a plurality of carriers, wherein a first set of the plurality of carriers is a single-TRP carrier, and a second set of the plurality of carriers is a multi-TRP carrier (block 610). For example, as described above, the UE (e.g., using antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller / processor 280, etc.) may receive configuration information for a plurality of carriers.

For example, as described above, the UE (e.g., using antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller / processor 280, etc.) may determine a distribution satisfying the per-span capability of the UE for the plurality of carriers. In some aspects, the distribution is a distribution of at least one of a plurality of non-overlapping CCEs or a plurality of blind decodings.
