[0038] The following will describe the technical solutions in the embodiments of this application in conjunction with the drawings in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0039] FIG1 is a schematic diagram of an application scenario of an embodiment of the present application.

[0040] As shown in Figure 1, a communication system 100 may include a terminal device 110 and a network device 120. The network device 120 may communicate with the terminal device 110 via an air interface. The terminal device 110 and the network device 120 support multi-service transmission.

[0041] It should be understood that the embodiments of the present application are only illustrative of the communication system 100, but the embodiments of the present application are not limited thereto. That is, the technical solutions of the embodiments of the present application can be applied to various communication systems, such as: Long Term Evolution (LTE) system, LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS), Internet of Things (IoT) system, Narrow Band Internet of Things (NB-IoT) system, enhanced Machine-Type Communications (eMTC) system, 5G communication system (also known as New Radio (NR) communication system), or future communication systems.

[0042] In the communication system 100 shown in Figure 1, the network device 120 may be an access network device that communicates with the terminal device 110. The access network device may provide communication coverage for a specific geographical area and may communicate with the terminal device 110 (eg, UE) located within the coverage area.

[0043] The network device 120 may be an evolved Node B (eNB or eNodeB) in a Long Term Evolution (LTE) system, or a Next Generation Radio Access Network (NG RAN) device, or a base station (gNB) in an NR system, or a wireless controller in a Cloud Radio Access Network (CRAN), or the network device 120 may be a relay station, an access point, an in-vehicle device, a wearable device, a hub, a switch, a bridge, a router, or a network device in a future evolved Public Land Mobile Network (PLMN), etc.

[0044] The terminal device 110 may be any terminal device, including but not limited to a terminal device connected to the network device 120 or other terminal devices by wire or wireless connection.

[0045] For example, the terminal device 110 may refer to an access terminal, user equipment (UE), a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent, or a user apparatus.

[0047] The wireless communication system 100 may further include a core network device 130 that communicates with the network device 120. The core network device 130 may be a 5G core network (5G Core, 5GC) device, such as an Access and Mobility Management Function (AMF), an Authentication Server Function (AUSF), a User Plane Function (UPF), or a Session Management Function (SMF). Optionally, the core network device 130 may also be an Evolved Packet Core (EPC) device of an LTE network, such as a Session Management Function + Core Packet Gateway (SMF+PGW-C) device. It should be understood that SMF+PGW-C can simultaneously implement the functions that can be implemented by SMF and PGW-C. During the network evolution process, the above-mentioned core network device may also be called other names, or a new network entity may be formed by dividing the functions of the core network, which is not limited in the embodiments of the present application.

[0048] The functional units in the communication system 100 may also establish connections and implement communication via next generation (NG) network interfaces.

[0050] Figure 1 exemplarily shows a network device, a core network device and two terminal devices. Optionally, the wireless communication system 100 may include multiple network devices and each network device may include other numbers of terminal devices within its coverage area, which is not limited in this embodiment of the present application.

[0051] It should be noted that Figure 1 is merely an example of a system applicable to this application. Of course, the methods described in the embodiments of this application can also be applied to other systems. Furthermore, the terms "system" and "network" are often used interchangeably herein. The term "and / or" herein simply describes an association relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " generally indicates that the associated objects are in an "or" relationship. It should also be understood that the "indication" mentioned in the embodiments of this application can be a direct indication, an indirect indication, or an indication of an association relationship. For example, "A indicates B" can mean that A directly indicates B, for example, B can obtain information through A; it can also mean that A indirectly indicates B, for example, A indicates C, and B can obtain information through C; or it can mean that A and B have an association relationship. It should also be understood that the "correspondence" mentioned in the embodiments of this application can mean that there is a direct or indirect correspondence between two objects, or that there is an association relationship between the two objects, or a relationship between an indicator and the indicated, a configuration and the configured, and so on. It should also be understood that the “predefined” or “predefined rules” mentioned in the embodiments of the present application can be implemented by pre-saving corresponding codes, tables or other methods that can be used to indicate relevant information in devices (for example, including terminal devices and network devices), and the present application does not limit its specific implementation method. For example, predefined can refer to what is defined in the protocol. It should also be understood that in the embodiments of the present application, the “protocol” may refer to a standard protocol in the field of communications, such as LTE protocols, NR protocols, and related protocols used in future communication systems, and the present application does not limit this.

[0052] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below. The following relevant technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the protection scope of the embodiments of the present application.

[0053] In the process of communication technology evolution, standard version 15 (R15) only supports a single antenna panel or a single receive beam / chain to receive downlink signals / channels. R16 enhances the receiving capability of terminal devices in carrier aggregation scenarios, and terminal devices can support receiving signals / channels on different carriers simultaneously in an independent beam management (IBM) manner. IBM requires terminal devices to have multiple baseband and RF processing functions, and to be able to use different Rx beams on different carriers to use different panels to simultaneously receive multiple downlink signals / channels. In addition, R16 introduces the ability to use multiple Rx beams for reception on the same carrier simultaneously in the evolved Multiple-In Multiple-Out (MIMO) technology. This capability is usually indicated by the parameter "simultaneousReceptionDiffTypeD". The parameter "simultaneousReceptionDiffTypeD" can be understood as the simultaneous reception of two different Quasi Co-Location (QCL) Type D channels / signals. Since different QCL Type Ds represent different receiving spatial information, the terminal device needs to use multiple RX beams to receive both channels / signals.

[0054] However, the current protocol does not clearly define how to use multiple RX beams simultaneously on the same carrier. For simultaneous reception of channels / signals from different directions on a single carrier, scheduling / measurement constraints need to be clearly defined.

[0055] The following describes scheduling / measurement limitations in related technologies.

[0056] 1. Scheduling / measurement restrictions at Layer 1 (L1).

[0057] L1 is the physical layer, and L1 measurement scenarios may include at least one of the following: Radio Link Monitoring (RLM), Candidate Beam Detection (CBD), Beam Failure Detection (BFD), Layer 1 Reference Signal Received Power (L1-RSRP), and Layer 1 Signal to Interference plus Noise Ratio (L1-SINR). The above measurements can be based on the Synchronization Signal / PBCH Block (SSB) or the Channel State Information Reference Signal (CSI-RS) resources.

[0058] For traditional terrestrial networks (TN), the L1 measurement time needs to meet the following requirements: 1) L1 measurement is kept outside the Measurement Gap (MG), 2) the FR1 frequency band supports simultaneous measurement of L1 and Layer 3 (L3), and 3) the FR2 frequency band does not support simultaneous measurement of L1 and L3.

[0059] 1.1. Scheduling availability of L1.

[0060] For the RLM scenario in frequency range 2 (i.e., high frequency FR2 band), the following scheduling restrictions may apply: if the transmission configuration indicator (TCI) state of the currently activated physical downlink control channel (PDCCH) / physical downlink shared channel (PDSCH) is QCL type D and the CSI-RS resources are repeated, no scheduling restrictions are required. Otherwise, the terminal device cannot send or receive data on the time domain unit (e.g., OFDM symbol) where the reference signal for RLM measurement is located.

[0061] For the scenario of performing intra-band carrier aggregation in FR2, the scheduling restriction applies to all serving cells in the same frequency band on time domain units that fully or partially overlap with the restricted time domain units (eg, OFDM symbols).

[0062] For scenarios where inter-band carrier aggregation is performed in FR2, if the terminal device is capable of independent beam management of the FR2 band pair, there are no scheduling restrictions on the serving cell in the FR2 band in the following cases:

[0063] RLM is performed on FR2 serving a Primary Cell (PCell) or Primary Secondary Cell (PSCell) in different frequency bands, and the terminal device is configured to have the same or different subcarrier spacing (typically characterized using parameter-level numerology) between SSB on one FR2 band and data on another FR2 band.

[0064] In addition, for FR2, if the following conditions are met: the terminal device has been notified of the system information update through a paging message, or the terminal device monitors and notifies the PDCCH of the system information update in the common search space (CSS) of the type 2 PDCCH, and the gap between the PDCCH monitored in the type 0 PDCCH CSS is greater than 2 time slots, at this time, for the SSB used for RLM and the control resource set (CORESET) for the remaining system information (RMSI) scheduling multiplexing mode 3, the terminal device expects to receive the PDCCH and the corresponding PDSCH monitored by the terminal device in the Type0-PDCCH CSS on the time domain unit of the SSB used for RLM measurement, and, for the SSB used for RLM and the CORESET for RMSI scheduling multiplexing mode 2, the terminal device expects to receive the PDCCH and the corresponding PDSCH monitored by the terminal device in the type 0 PDCCH CSS set on the time domain unit of the SSB used for RLM measurement.

[0065] 1.2. Measurement restriction of L1.

[0066] When a signal used for RLM / BFD / CBD / L1-RSRP / L1-SINR measurement conflicts with other signals used for RLM / BFD / CBD / L1-RSRP / L1-SINR measurement in the same time domain unit (e.g., OFDM symbol), measurement restrictions are required in the following situations.

[0067] First, the measurement limitations based on SSB are introduced.

[0068] For frequency band type 1 (i.e., low frequency FR1), when the SSB used for RLM / BFD / CBD / L1-RSRP / L1-SINR measurement collides with the CSI-RS used for RLM / BFD / CBD / L1-RSRP measurement in the same time domain unit (e.g., OFDM symbol), if the SSB and CSI-RS have the same subcarrier spacing (SCS), the terminal device should be able to perform the measurement without any restrictions.

[0069] If the SSB and CSI-RS have different SCSs and the terminal device supports the ability to process different parameter levels (Numerology) simultaneously, usually characterized by the parameter "simultaneousRxDataSSB-DiffNumerology", the terminal device should be able to perform measurements without any restrictions. If the SSB and CSI-RS have different SCSs and the terminal device does not support the simultaneousRxDataSSB-DiffNumerology capability, the terminal device is restricted to measuring one of the SSB and CSI-RS, but not both at the same time.

[0070] For FR2, when the SSB and CSI-RS are in the same time domain unit (e.g., OFDM symbol) on the same component carrier (CC), or the SSB and CSI-RS are configured with different Numerologies, and the SSB and CSI-RS are on different FR2 frequency bands, and the terminal device does not have IBM capability, the terminal device is limited to measuring one of the SSB and CSI-RS and cannot measure both at the same time.

[0071] The following describes the measurement restrictions based on CSI-RS.

[0072] For FR1 and FR2, when the CSI-RS for RLM measurement and the SSB for RLM / BFD / CBD / L1-RSRP measurement are in the same time domain unit (e.g., OFDM symbol), the terminal device does not need to receive the CSI-RS for RLM measurement in the physical resource block (PRB) overlapping with the SSB.

[0073] For FR2, when the CSI-RS for RLM measurement on one CC is in the same time domain unit (e.g., OFDM symbol) as the SSB for RLM / BFD / L1-RSRP measurement on the same CC or different CCs in the same frequency band, or in the same time domain unit (e.g., OFDM symbol) as the SSB for CBD measurement on the same CC or different CCs in the same frequency band when beam failure is detected, the terminal device needs to measure either CSI-RS or SSB, but not both at the same time. CSI-RS-based measurements are expected to have longer measurement periods and no requirements are defined.

[0074] For FR2, in the same CC or different CCs of the same frequency band, when the time domain resource of the first CSI-RS used for L1-RSRP measurement is in the same time domain unit (e.g., OFDM symbol) as the time domain resource of the second CSI-RS used for RLM, BFD, CBD, or L1-RSRP measurement, in the following cases, the terminal device needs to measure one of the first CSI-RS and the second CSI-RS, but not both at the same time. Measurement based on the first CSI-RS or the second CSI-RS is expected to have a longer measurement period:

[0075] The first CSI-RS resource or the second CSI-RS resource is configured as a repeated resource;

[0076] The first CSI-RS and / or the second CSI-RS are configured in a beam detection parameter set, and a beam failure of the first CSI-RS and / or the second CSI-RS is detected;

[0077] The type of QCL information associated with the first CSI-RS and the second CSI-RS is not type D, or the QCL information of the first CSI-RS and the second CSI-RS is unknown information (ie, the terminal device does not know the QCL information).

[0078] In addition to the above scenarios, the terminal device should be able to measure the first CSI-RS and the second CSI-RS without any restrictions.

[0079] In summary, the L1 measurement limits for FR2 can be found in Table 1.

[0080] Table 1

[0081]

[0082] 2. Scheduling / measurement restrictions at Layer 3 (L3).

[0083] L3 measurements are primarily used for mobility management. Based on the reference signal type, they can be categorized as SSB-based and CSI-RS-based. Based on the reference signal frequency / bandwidth configuration, they can be categorized as intra-frequency and inter-frequency measurements. For example, intra-frequency SSB measurements are further categorized as requiring MG measurements based on the terminal device's capabilities and SSB configuration.

[0084] SSB-based L3 measurements are primarily performed based on the SSB measurement timing configuration (SS / PBCH block measurement timing configuration, SMTC) window, and the measurement time takes into account the SMTC period. CSI-RS-based L3 measurements currently do not have a measurement window configured, and the measurement time is calculated directly based on the CSI-RS signal period.

[0085] It should be understood that L1 RLM / BFD / CBD / L1-RSRP / L1-SINR measurements require the terminal device to perform the measurements outside the MG, and the measured signal must be within the activated bandwidth part (BWP). In the current protocol, L1 measurements must be separated from L3 measurements, that is, they must avoid the MG or measurement time window configured for L3 measurements, such as SMTC.

[0086] For L3 measurements that require the use of an MG, the MG is reserved by default for measurement, so there are no scheduling restrictions. However, for L3 measurements that do not use an MG, scheduling restrictions are required.

[0087] The following describes the scheduling restrictions for intra-frequency SSB without using MG. It should be noted that the scheduling restrictions for intra-frequency SSB using Network Controlled Small Gap (NCSG) are the same.

[0088] Specifically, the following scheduling restrictions apply to SS-RSRP or SS-SINR measurements on cells within FR2:

[0089] The terminal device does not expect to send PUCCH / PUSCH / SRS for channel quality indicator (CQI) or receive PDCCH / PDSCH / TRS / CSI-RS on the time domain unit (e.g., OFDM symbol) of the SSB to be measured, and the above transmission or reception is on 1 time domain unit before each SSB time domain unit to be measured and on 1 time domain unit after each SSB time domain unit to be measured within the SMTC window duration.

[0090] The following scheduling restrictions apply to SS-RSRQ measurements on cells within FR2 frequency.

[0091] The terminal device does not expect to transmit PUCCH / PUSCH / SRS within the SMTC window duration or receive PDCCH / PDSCH / TRS / CSI-RS for CQI on the time domain unit of the SSB to be measured, the time domain unit of the RSSI measurement, and 1 time domain unit before each consecutive SSB to be measured and 1 time domain unit after each consecutive SSB to be measured.

[0092] The following describes the scheduling restrictions for intra-frequency SSB using MG.

[0093] Specifically, the following scheduling restrictions apply to SS-RSRP or SS-SINR measurements on FR2 inter-frequency cells:

[0094] During the SMTC window duration, the terminal device does not expect to transmit PUCCH / PUSCH / SRS for CQI measurement or receive PDCCH / PDSCH / TRS / CSI-RS on the time domain unit of the SSB to be measured, on 1 time domain unit before each time domain unit of consecutive SSBs to be measured, and on 1 time domain unit after each time domain unit of consecutive SSBs to be measured.

[0095] The following scheduling restrictions apply to SS-RSRQ measurements on FR2 inter-frequency cells:

[0096] During the SMTC window duration, the terminal device does not expect to send PUCCH / PUSCH / SRS or receive PDCCH / PDSCH / TRS / CSI-RS for CQI measurement in the time domain unit of the SSB to be measured, the time domain unit of RSSI measurement, and the time domain unit before each consecutive SSB to be measured and the time domain unit after each consecutive SSB to be measured.

[0097] The following describes scheduling restrictions for inter-frequency CSI-RS without using measurement gaps.

[0098] When the CSI-RS resource is completely contained in the BWP activated by the terminal device, the terminal device needs to be able to measure without measurement gaps. It should be noted that the time domain unit of the configured CSI-RS is represented by the firstOFDMSymbolInTimeDomain contained in the CSI RS ResourceConfigMobility of RRM. When the terminal device needs to perform CSI-RS-based RRM measurements and any of the following conditions are met, the scheduling availability is restricted; otherwise, there is no scheduling restriction.

[0099] Scheduling restrictions for performing CSI-RS based measurements in the TDD band: When a terminal device performs intra-frequency measurements of CSI-RS in the TDD band, the terminal device does not expect to transmit PUCCH / PUSCH / SRS on the time domain unit of the configured CSI-RS resources and on the time domain unit before and after each consecutive configured CSI-RS time domain unit. When performing TDD intra-band carrier aggregation, scheduling restrictions due to a given serving cell should also apply to all other serving cells in the same band on time domain units that fully or partially overlap with the above restricted time domain units.

[0100] Scheduling restrictions based on CSI-RS measurements are performed in FR2. When a terminal device performs CSI-RS based intra-frequency measurements for L3 mobility management in FR2, the terminal device does not expect to transmit PUCCH / PUSCH / SRS or receive PDCCH / PDSCH / TRS / CSI-RS for CQI on the time domain elements of the CSI-RS within the configured timeslot, as indicated in the timeslot configuration of the corresponding CSI-RS resource for which mobility is to be measured.

[0101] When performing intra-band carrier aggregation in FR2, scheduling restrictions due to a given serving cell should also apply to all other serving cells in the same frequency band on time domain units that fully or partially overlap with the above restricted time domain units.

[0102] In addition, when inter-band carrier aggregation is performed in FR2, since CSI-RSRP, CSI-RS RQ or CSI-SINR measurements are performed on FR2 intra-frequency cells in different frequency bands, there are no scheduling restrictions on the FR2 serving cell in the frequency band, provided that the terminal device is capable of independent beam management for the FR2 frequency band pair.

[0103] As can be seen, the L1 / L3 measurement and scheduling requirements in the existing protocols are based on receiving signals from a single receive beam (Rx beam). However, with the introduction of multi-beam reception, certain measurement or scheduling-restricted scenarios need to be considered accordingly due to changes in the terminal device's ability to support simultaneous FR2 multi-beam reception. For example, the terminal device's receive beam scanning mechanism during measurement changes, whether the processing capabilities of the RF / antenna panel and baseband are decoupled, and whether multi-beam is merely an enhancement of antenna or RF capabilities, and whether the corresponding baseband capabilities are also enhanced.

[0104] This solution will address the above issues based on the different capabilities or implementations supported by terminal devices, and improve the scheduling or measurement restriction requirements of terminal devices during measurement.

[0105] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The above related technologies can be combined arbitrarily with the technical solutions of the embodiments of the present application as optional solutions, and all of them fall within the scope of protection of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0106] The wireless communication method provided in the embodiment of the present application, as shown in FIG2 , includes:

[0107] Step 210: When the terminal device supports the first capability, determine that there are no measurement restrictions and / or scheduling restrictions in the first scenario. The first capability is at least used to indicate that the terminal device can simultaneously receive multiple channels and / or signals on multiple receiving beams. The first scenario is a scenario in which the time domain resources of the multiple channels and / or signals to be received by the terminal device overlap.

[0108] It should be understood that a terminal device supporting the first capability can simultaneously receive multiple channels and / or signals in different directions through multiple receiving beams, wherein the number of the multiple receiving beams can be two or more, and different receiving beams correspond to different directions.

[0109] Exemplarily, as shown in reference figures 3A and 3B, the terminal device can be configured with 4 receiving beams, and these 4 receiving beams can simultaneously receive up to 4 channels and / or signals (for example, 4 channels, or 4 signals, or 2 channels and 2 signals, etc.). As shown in reference figure 3A, the terminal device can simultaneously receive multiple channels and / or signals from one cell. Specifically, the multiple channels and / or signals can be sent by a base station in the cell through different beams, and the multiple channels and / or signals can also be sent by beams of different transmission / reception points (TRP) in the cell. The embodiments of the present application do not impose any restrictions on this. As shown in reference figure 3B, the terminal device can simultaneously receive multiple channels and / or signals from different cells or different TRPs.

[0110] Optionally, the signal mentioned in the embodiment of the present application may be a reference signal used for measurement, such as SSB, CSI-RS, positioning reference signal (PRS), etc., and the embodiment of the present application is not limited to this.

[0111] Optionally, the channels mentioned in the embodiment of the present application may include PDSCH, PDCCH, and other downlink channels, and the embodiment of the present application does not limit this.

[0112] It should be understood that the measurement and scheduling in the existing protocol are formulated based on the reception of signals by a single receiving beam (Rx beam), and the measurement and scheduling in certain scenarios are subject to more restrictions. For example, in a scenario where the time domain resources of multiple channels and / or signals to be received by the terminal device overlap, under certain conditions, the terminal device can only receive one of the multiple channels and / or signals, and the terminal device needs to traverse all Rx beams to obtain the final measurement results. In an embodiment of the present application, when the terminal device has the ability to simultaneously receive signals / signals with multiple beams, it can be determined that measurement restrictions and / or scheduling restrictions are no longer imposed in certain scenarios. That is, the terminal device can remove the original measurement restrictions and / or scheduling restrictions based on its ability to simultaneously receive multiple beams. In this way, the terminal device can reduce the measurement time and the data transmission time, and improve the efficiency of the measurement and the efficiency of the data transmission.

[0113] Accordingly, on the network side, the network device may also determine that the terminal device has no measurement restrictions and / or scheduling restrictions in the first scenario if the terminal device supports the first capability. In this way, the network device can simultaneously transmit multiple signals and / or channels to the terminal device using transmit beams in different directions. This reduces the time required for signal-based measurements and data transmission by the terminal device, thereby improving measurement efficiency and data transmission efficiency.

[0114] Optionally, the first capability may include at least one of the following:

[0115] The ability to simultaneously receive multiple reference signals of different types on multiple receive beams;

[0116] The ability to simultaneously receive multiple reference signals for different purposes on multiple receive beams;

[0117] The ability to simultaneously receive multiple reference signals in different configurations on multiple receive beams;

[0118] The ability to simultaneously receive at least one reference signal and at least one channel on multiple receive beams;

[0119] The ability to process multiple channels and / or signals separately through multiple baseband processing units;

[0120] The ability to receive multiple channels and / or signals separately via multiple radio frequency links.

[0121] Optionally, the multiple different types of reference signals include at least two of SSB, CSI-RS, and PRS. Exemplarily, if the terminal device is configured with two antenna panels, corresponding to two receiving beams in different directions, the first capability may include the ability to simultaneously receive SSB and CSI-RS on the two receiving beams, or the ability to simultaneously receive SSB and PRS on the two receiving beams, or the ability to simultaneously receive CSI-RS and PRS on the two receiving beams. In addition, if the terminal device is configured with three antenna panels, corresponding to three receiving beams in different directions, the first capability may include the ability to simultaneously receive SSB, CSI-RS, and PRS on the three receiving beams. The first capability may also include the ability to simultaneously receive one SSB and two different CSI-RS on the three receiving beams. The first capability may also include the ability to simultaneously receive other reference signal combinations, which are enumerated here one by one.

[0122] Optionally, the multiple reference signals for different purposes include at least two of the following: SSB for RLM, SSB for CBD, SSB for BFD, SSB for L1-RSRP measurement, SSB for L1-SINR measurement, SSB for layer 3 measurement, CSI-RS for RLM, CSI-RS for CBD, CSI-RS for BFD, CSI-RS for L1-RSRP measurement, CSI-RS for L1-SINR measurement, CSI-RS for CQI, CSI-RS for layer 3 measurement, PRS for RSRP measurement, PRS for reference signal time difference (RSTD) measurement; and PRS for Rx-Tx time difference (RTT) measurement of the time difference received and transmitted by the terminal device.

[0123] It should be understood that the first capability may include the ability to simultaneously receive multiple reference signals of the same type but for different purposes on multiple receive beams. For example, if the terminal device is configured with two antenna panels, each corresponding to receive beams in two different directions, the first capability may include the ability to simultaneously receive CSI-RS for RLM and CSI-RS for CBD on the two receive beams, or other combinations of the same type but for different purposes, which are not enumerated here.

[0124] In addition, the first capability may also include the ability to simultaneously receive multiple reference signals of different types and uses on multiple receive beams. For example, if the terminal device is configured with two antenna panels, each corresponding to receive beams in two different directions, the first capability may include the ability to simultaneously receive SSB for RLM and CSI-RS for CBD on the two receive beams, or other combinations of different types and uses, which are not enumerated here.

[0125] It should be noted that, when the terminal device does not clearly indicate the purpose of the reference signal, the reference signal can be used for any purpose.

[0126] Optionally, the configuration of the reference signal includes at least one of the following: sub-carrier spacing (SCS), resource block (RB), bandwidth, and resource type.

[0127] It should be understood that the first capability may include the ability to simultaneously receive multiple reference signals of the same type but with different configurations on multiple receiving beams. For example, the first capability may include receiving multiple CSI-RS / CSI-RS / PRS with different subcarrier spacings on multiple receiving beams, or the first capability may include simultaneously receiving SSB / CSI-RS / PRS with different numbers of RBs on multiple receiving beams, or the first capability may include simultaneously receiving multiple SSB / CSI-RS / PRS with different SCSs and different numbers of RBs on multiple receiving beams. The embodiments of the present application are not limited to this.

[0128] The first capability may also include the ability to simultaneously receive multiple reference signals of different types and configurations on multiple receive beams. For example, the first capability may include receiving CSI-RS and SSB with different SCSs on multiple receive beams. The first capability may also include the ability to simultaneously receive multiple reference signals of the same type but with different uses and configurations on multiple receive beams. This embodiment of the present application is not limited to this.

[0129] It should be noted that the ability to simultaneously receive at least one reference signal and at least one channel on multiple receiving beams may specifically include simultaneously receiving at least one reference signal and at least one signal with the same configuration (for example, the same SCS, PB, bandwidth, etc.) on multiple receiving beams, or simultaneously receiving at least one reference signal and at least one signal with different configurations (for example, different SCS, PB, bandwidth, etc.) on multiple receiving beams.

[0130] Optionally, the first capability may also include enhanced terminal device baseband processing capabilities and / or enhanced radio frequency (RF) capabilities. The enhanced terminal device baseband processing capabilities specifically refer to the terminal device having multiple independent baseband processing units, and the terminal device can process multiple received channels and / or signals separately (or simultaneously) through multiple baseband processing units. The enhanced RF capability may refer to the terminal device having multiple independent radio frequency links, and the terminal device can receive multiple channels and / or signals separately through multiple radio frequency links.

[0131] For example, FIG4 shows a schematic diagram of the structure of a processing chip, which may include an RF modem controller (RF Modem), a beamforming RF chip, a baseband processing chip, and a battery management chip. It should be understood that for enhanced terminal device baseband processing capabilities, the baseband processing chip may include multiple independent processing units (cores) that can independently process different channels and / or signals. For enhanced RF capabilities, the chip may include two RF links (IF1 and IF2), and the terminal device can receive multiple channels and / or signals through multiple RF links.

[0132] Optionally, the enhanced terminal device baseband processing capability can be indicated by the parameter "independentBaseChain". The common device baseband processing capability can be indicated by the parameter "commonBaseChain".

[0133] It should be understood that when the terminal device supports enhanced terminal device baseband processing capabilities, measurement restrictions and / or scheduling restrictions may not be imposed.

[0134] Optionally, the embodiment of the present application may expand and enhance the parameter “simultaneousReceptionDiffTypeD” in the existing protocol, and indicate different capabilities through the enhanced parameter “simultaneousReceptionDiffTypeD”.

[0135] It should be understood that the parameter "simultaneousReceptionDiffTypeD" is used to indicate that the terminal device can simultaneously receive channels and / or signals associated with two different QCL type-D types of QCL information. Since different QCL type D means different reception space information, that is, the terminal device can use multiple Rx beams to receive these two channels and / or signals at the same time. It should be noted that the parameter "simultaneousReceptionDiffTypeD" in the existing protocol represents the ability of two TRPs with the same parameter configuration to transmit simultaneously, where the reference configuration may include SCS, SSB+SSB, CSI-RS+CSI-RS / data, SSB+CSI-RS, within activated BWP, etc.

[0136] Exemplarily, the terminal device can use the enhanced parameter "simultaneousReceptionDiffTypeD_mixRS" to indicate that the terminal device supports the ability to simultaneously receive multiple reference signals of different types on multiple receive beams. If the SCSs of multiple reference signals of different types are different, where the SCS can be indicated by the parameter set "Numerology", the terminal device can also use the parameter "simultaneousReceptionDiffTypeD_mixRS" and the parameter "simultaneousRxDataSSB-DiffNumerology" to jointly indicate that the terminal device has the ability to simultaneously receive multiple different types of reference signals with different SCSs on receive beams in different directions.

[0137] For example, the terminal device may use the enhanced parameter "simultaneousReceptionDiffTypeD_CSIandCSI" to indicate that the terminal device supports simultaneous reception of two or more CSI-RS resources on multiple receive beams. When the SCSs of multiple CSI-RS resources are different, the terminal device may combine the parameter "simultaneousReceptionDiffTypeD_CSIandCSI" and another parameter "simultaneousRxDataSSB-DiffNumerology" to jointly indicate that the terminal device has the ability to simultaneously receive multiple CSI-RSs with different SCSs on receive beams in different directions.

[0138] Exemplarily, the terminal device can indicate through "simultaneousReceptionDiffTypeD_CSIforBMandCQI" that the terminal device supports the ability to simultaneously receive multiple CSI-RSs for different purposes on multiple receive beams. The "BM" in the above parameters refers to beam management, which can include two uses: CBD and FBD. In addition, when the SCSs of multiple CSI-RSs for different purposes are different, the terminal device can also combine the parameter "simultaneousReceptionDiffTypeD_CSIforBMandCQI" and another parameter "simultaneousRxDataSSB-DiffNumerology" to jointly indicate that the terminal device has the ability to simultaneously receive CSI-RSs for BM and CSI-RSs for CQI with different SCSs on multiple receive beams.

[0139] For example, the terminal device can indicate through the parameter "simultaneousReceptionDiffTypeD_mixRSandData" that the terminal device supports the ability to simultaneously receive reference signals and conventional downlink channels on multiple receive beams. In addition, further distinctions can be made based on the differences between reference signals and downlink data, such as the parameter "simultaneousReceptionDiffTypeD_mixSSBandPDCCH", and the parameter "simultaneousReceptionDiffTypeD_mixSSBandPDSCH". Similarly, the terminal device can also combine the parameter "simultaneousRxDataSSB-DiffNumerology" to indicate that the terminal device supports the ability to simultaneously receive different reference signals and downlink channels of SCS through different receive beams.

[0140] It should be understood that in addition to the above-mentioned combination of two different parameters to indicate that the terminal device supports the simultaneous reception of channels and / or channels of different SCSs through multiple receive beams, new parameters can also be defined for direct indication. For example, the terminal device can indicate the ability of the terminal device to support the simultaneous reception of different SCS reference signals and downlink channels through different receive beams through only one parameter "simultaneousRxSSBdata-DiffSCS&diffTypeD". The embodiment of the present application does not limit the above-mentioned indication method.

[0141] Optionally, as shown in FIG5 , the wireless communication method provided in the embodiment of the present application may further include:

[0142] Step 220: The terminal device sends device capability information to the network device, where the device capability information is used to indicate a first capability.

[0143] It is understandable that the terminal device may report the capabilities it supports to the network device, so that the network device determines whether to release the measurement and / or scheduling restrictions on the terminal device in the first scenario through the first capability.

[0144] It should be noted that step 220 can be performed before step 210, or after step 210, or simultaneously, and the embodiment of the present application does not limit this.

[0145] Optionally, the device capability information may be reported to the network device via Radio Resource Control (RRC) signaling or Medium Access Control (MAC) signaling. The embodiment of the present application does not impose any restrictions on the reporting method.

[0146] Optionally, the object targeted by the first capability in the embodiment of the present application may include at least one of the following:

[0147] Terminal equipment, frequency band, and frequency band combination.

[0148] It should be understood that the first capability may be the capability of the terminal device, that is, if the terminal device indicates the first capability through the device capability information, it indicates that the terminal device can support the first capability in all frequency bands, thereby reducing the signaling overhead of reporting the terminal capability.

[0149] The first capability can also be specific to a frequency band combination, that is, a per-band pair capability. Different frequency band combinations can independently report corresponding first capabilities. For example, the first capability can be the ability to simultaneously receive multiple channels and / or channels using multiple receive beams on a specific carrier pair (band pair). It should be understood that independently reporting different frequency band combinations increases the implementation freedom of the terminal device to a certain extent.

[0150] The first capability can also be frequency band specific, that is, a per-band capability. Different frequency bands can independently report their corresponding first capabilities. For example, the first capability can be the ability to simultaneously receive multiple channels and / or channels using multiple receive beams on a specific carrier. It should be understood that independently reporting different frequency bands allows for greater flexibility in terminal device implementation.

[0151] Optionally, with reference to FIG6 , the wireless communication method provided in the embodiment of the present application may further include the following steps:

[0152] Step 230: The terminal device sends first indication information to the network device. The first indication information is used to indicate at least one of the following:

[0153] a maximum number of the plurality of receive beams;

[0154] The multiple receiving beams can be used for measurement simultaneously;

[0155] The multiple receiving beams can be used for measurement and channel reception simultaneously;

[0156] the number of receive beams in the plurality of receive beams that can be used for measurement;

[0157] the number of receive beams in the plurality of receive beams that can be used for layer one measurement;

[0158] the number of receive beams in the plurality of receive beams that can be used for layer 3 measurement;

[0159] The number of receive beams among the plurality of receive beams that can be used for channel reception.

[0160] It should be understood that the terminal device can report to the network device the maximum number of Rx beams that it can use for simultaneous reception. Different receive beams can be implemented by different antennas, different antennas have different spatial coverage, and different antennas have different angles of arrival (AOA). As shown in Figures 7A-7C, spatial coverage 701 and spatial coverage 702 are implemented based on different antennas and correspond to different AOAs. The relationship between spatial coverage 701 and spatial coverage 702 may include: different sizes and no overlap as shown in Figure 7A, the same size and no overlap as shown in Figure 7B, and the same size and overlap as shown in Figure 7C.

[0161] Optionally, the terminal device may indicate this through the parameter “MaxnumSimReceptionDiffTypeD”, exemplarily, Nsim_Rx_beam={1, 2, 3, 4}.

[0162] It should be noted that the number of beams corresponding to the multiple channels and / or signals to be received is less than or equal to the maximum number of multiple receive beams in step 210. In other words, the number of actual transmit beams of the network device is less than the maximum number of Rx beams that the terminal device can simultaneously receive. In this way, different antennas of the terminal device can correspond to different network device transmit beams, ensuring that the terminal device can simultaneously receive multiple channels and / or signals.

[0163] Optionally, the terminal device may further indicate to the network device, through the second indication information, the functions that the Rx beam that the terminal device can use to simultaneously receive wants / can achieve.

[0164] For example, a terminal device may use the signaling parameter "SimL1AndL3MeasDiffTypeD" to report that it desires / can use multiple Rx beams for simultaneous L1 and L3 measurements. A terminal device may use the signaling parameter "SimMeasAndDataDiffTypeD" to report that it desires / can use multiple Rx beams for simultaneous measurement and downlink channel / signal reception.

[0165] Optionally, the terminal device may further report the number of Rx beams implementing each function through the second indication information.

[0166] For example, the terminal device can report the number of Rx beams that it wants / can use for L3 measurement through the signaling parameter "numSimL3MeasDiffTypeD", the number of Rx beams that it wants / can use for L1 measurement through the parameter "numSimL1MeasDiffTypeD", and the number of Rx beams that it wants / can use for channel reception through the parameter "numSimDataDiffTypeD".

[0167] Optionally, the above-mentioned first indication information can be reported to the network device via RRC signaling or MAC signaling. The embodiment of the present application does not limit the reporting method.

[0168] It should be noted that the first indication information and the device capability information can be transmitted in the same signaling or in different signaling, and this embodiment of the present application does not impose any limitation on this.

[0169] Optionally, as shown in FIG6 , the wireless communication method provided in the embodiment of the present application may further include the following contents:

[0170] Step 240: The network device sends second indication information to the terminal device, where the second indication information is used to indicate the function of each of the multiple receiving beams.

[0171] It should be understood that the network device can specify the role of each receive beam based on actual needs. That is, the network device can use the second indication information to indicate to the terminal device which of the multiple receive beams configured is used for receiving the reference signal and which is used for receiving the channel. For example, the terminal device can specify corresponding roles for different beams based on the direction and angle of the receive beam.

[0172] Optionally, the network device may also determine the role of each receiving beam based on the device capability information and / or the first indication information reported by the terminal device. Exemplarily, the network device may set the role of each receiving beam based on the type and number of multiple channels and / or signals to be sent, and based on the number of receiving beams that can be used for layer 1 measurement indicated in the first indication information. Exemplarily, the network device may also determine whether the carriers of the multiple channels and / or signals to be sent are the same carrier or other scenarios, and determine the role of each receiving beam based on the scenario and the device capability information and / or the first indication information reported by the terminal device, thereby actively avoiding measurement-limited and / or scheduling-limited problems and improving measurement and / or transmission efficiency.

[0173] In one embodiment of the present application, the terminal device and / or the network device may directly determine, based on the specific content of the first capability, that the terminal device has no measurement restrictions and / or scheduling restrictions in the first scenario.

[0174] Optionally, when the first capability includes at least one of the following, the terminal device and / or the network device determines that the terminal device has no measurement restriction in the first scenario:

[0175] The ability to simultaneously receive multiple reference signals of different types on multiple receive beams;

[0176] The ability to simultaneously receive multiple reference signals for different purposes on multiple receive beams;

[0177] The ability to simultaneously receive multiple reference signals in different configurations on multiple receive beams;

[0178] The ability to process multiple signals separately through multiple baseband processing units;

[0179] The ability to receive multiple channels and / or signals separately via multiple radio frequency links.

[0180] Exemplarily, when the time domain resources of the SSB and CSI-RS to be transmitted overlap (partially or fully), and the frequency domain resources of the SSB and CSI-RS to be transmitted belong to the same frequency band, if the first capability includes the ability to simultaneously receive multiple different types of reference signals on multiple receiving beams, this capability can be indicated by the parameter "simultaneousReceptionDiffTypeD_mixRS", then the terminal device can determine that no measurement restrictions are imposed, and the terminal device can measure the SSB and CSI-RS simultaneously.

[0181] When the time domain resources of the SSB and CSI-RS to be transmitted overlap (partially or completely), and the SSB and CSI-RS to be transmitted have different SCSs, if the first capability includes the ability to simultaneously receive multiple reference signals with different SCSs and different types on multiple receiving beams, the terminal device can determine not to impose measurement restrictions and measure the SSB and CSI-RS at the same time. The ability to simultaneously receive multiple reference signals with different SCSs and different types on multiple receiving beams can be indicated by the parameter "simultaneousReceptionDiffTypeD_mixRS" and the parameter "simultaneousRx-DiffNumerology&DifftypeD", or by an enhanced signaling parameter "simultaneousRxmixRS-DiffSCS&diffTypeD", and this embodiment of the present application does not impose any restrictions on this.

[0182] Optionally, when the first capability information includes at least one of the following items, the terminal device may determine that there is no scheduling restriction in the first scenario:

[0183] The ability to simultaneously receive multiple reference signals of different types on multiple receive beams;

[0184] The ability to simultaneously receive at least one reference signal and at least one channel on multiple receive beams.

[0185] Exemplarily, the time domain resources of the SSB and PDSCH to be transmitted overlap (partially or completely), and the frequency domain resources of the SSB and PDSCH to be transmitted belong to the same frequency band, or different frequency bands (the terminal device does not support IBM capabilities on different frequency bands). At this time, if the first capability includes the ability to simultaneously receive multiple different types of reference signals with different SCSs on multiple receiving beams, the terminal device determines that there are no scheduling restrictions. If the first capability does not include the ability to simultaneously receive multiple different types of reference signals with different SCSs on multiple receiving beams, it is determined that PDSCH cannot be received or sent on the conflicting time domain unit and the K time domain units before and after. The above-mentioned capability can be indicated by the enhanced parameter "simultaneousRxSSBdata-DiffSCS&diffTypeD", or by the parameter "simultaneousReceptionDiffTypeD_mixSSBandPDSCH" and the parameter "ltaneousRxDataSSB-DiffNumerology", which are not limited here.

[0186] Optionally, the terminal device's determination of whether to remove scheduling restrictions may also be related to the maximum number of Rx beams configured for the terminal device. For example, at the location of the reference signal conflicting time domain unit, the terminal device needs to receive N PDCCH / PDSCHs associated with different QCL type Ds. If N is less than the maximum number of Rx beams configured for the terminal device, there are excess Rx beams for measurement, and scheduling restrictions are not required. If N is greater than or equal to the maximum number of Rx beams configured for the terminal device, scheduling restrictions are required.

[0187] In another embodiment of the present application, the capabilities in the related art may not be expanded or enhanced. The terminal device and / or network device may reuse capability parameters in the related art. For example, if the first capability is "simultaneousReceptionDiffTypeD," when the time domain resources of multiple reference signals overlap, the terminal device may not impose measurement restrictions after meeting specific capability requirements. Correspondingly, if the specific terminal device capability requirements are not met, the terminal device needs to impose measurement restrictions.

[0188] Optionally, in some embodiments, the first scenario is specifically a scenario in which time domain resources of multiple signals to be received overlap. In step 210, if the terminal device supports the first capability, the terminal device determines that there are no measurement restrictions and / or scheduling restrictions in the first scenario, which can be achieved by:

[0189] In a case where the terminal device supports the first capability, if the terminal device satisfies a first condition, the terminal device determines that there is no measurement restriction in the first scenario; wherein the first condition includes at least one of the following:

[0190] The plurality of signals to be received are associated with a plurality of QCL information of QCL type D;

[0191] The multiple signals to be received are respectively associated with multiple different receiving beams;

[0192] The multiple signals to be received are processed by multiple different baseband processing units.

[0193] It should be understood that in the embodiment of the present application, the terminal device can use multiple Rx beams to simultaneously measure the reference signal to avoid measurement limitations caused by measurements between multiple reference signals.

[0194] The multiple signals to be received are associated with multiple different QCL information of QCL type D. This means that the multiple signals to be received are spatially independent and uncorrelated. Therefore, the terminal device can use independent receive beams in different directions on repeated time domain resources to receive signals and perform measurements. In other words, terminal devices that meet this condition are not subject to measurement restrictions.

[0195] When multiple signals to be received are respectively associated with multiple different receiving beams, the terminal device can use independent receiving beams in different directions to receive signals and perform measurements on repeated time domain resources. In other words, terminal devices that meet this condition are not subject to measurement restrictions.

[0196] Furthermore, multiple signals to be received are processed by multiple different baseband processing units. This means that the terminal device has enhanced baseband processing capabilities and can independently process different signals simultaneously. Therefore, the terminal device can use independent receive beams in different directions on overlapping time domain resources to receive signals and perform measurement processing. In other words, terminal devices that meet this condition are not subject to measurement restrictions.

[0197] It should be understood that if any one of the above first conditions is met, or any two of them are met, or all three of them are met, it can be determined that there is no measurement limitation.

[0198] Optionally, the frequency domain resources of the multiple signals to be received belong to the same carrier or different carriers of the same frequency band;

[0199] Alternatively, the frequency domain resources of the multiple signals to be received are located in different frequency bands, and the terminal device does not support independent beam management capabilities.

[0200] Optionally, the frequency domain resources of the multiple signals to be received may belong to a high frequency, such as an FR2 frequency domain interval.

[0201] It should be understood that when the frequency domain resources of the multiple signals to be received belong to the same carrier or different carriers of the same frequency band, or when the frequency domain resources of the multiple signals to be received are located in different FR2 frequency bands and the terminal device does not support IBM capability, if the multiple signals to be received are associated with multiple different QCL information of QCL type D indicating a spatial relationship, and / or, the multiple signals to be received are respectively associated with multiple different receiving beams, and / or, the multiple signals to be received are processed by multiple different baseband processing units, then it can be determined that the terminal device determines that there is no measurement restriction in the first scenario.

[0202] Optionally, in addition to determining whether to release the measurement restriction in addition to judging the above conditions, the terminal device needs to further determine the SCS of the multiple signals to be received. If the terminal device satisfies the first condition, the terminal device determines that there is no measurement restriction in the first scenario, which can also be achieved by:

[0203] If the terminal device satisfies the first condition and the terminal device satisfies the second condition, the terminal device determines that there is no measurement restriction in the first scenario; wherein the second condition may include: the subcarrier spacing of the multiple signals to be received is the same; or, the subcarrier spacing of the multiple signals to be received is different, and the terminal device supports the ability to simultaneously process signals with different subcarrier spacings.

[0204] It is understood that when the SCSs of multiple channels to be received are the same, the terminal device can simultaneously process multiple signals with the same SCS, and in this case, no measurement restrictions are imposed on the terminal device. When the SCSs of multiple channels to be received are different, the terminal device determines that there are no measurement restrictions only if the terminal device supports the ability to simultaneously process signals with different subcarrier spacings. Otherwise, the terminal device's measurement is restricted.

[0205] Optionally, if the terminal device does not meet any one of the first condition and the second condition, the terminal device performs measurement based on any one of the multiple signals to be received.

[0206] It should be understood that, in addition to supporting the first capability "simultaneousReceptionDiffTypeD", if the terminal device does not meet specific capability requirements, the measurement restriction cannot be lifted. In other words, once multiple signals collide in the time domain, only one measurement can be performed on the multiple signals.

[0207] In a feasible example, the multiple signals to be received may include an SSB and a CSI-RS, where the time domain resources of the SSB used for RLM / BFD / CBD / L1-RSRP / L1-SINR measurement and the CSI-RS used for RLM / BFD / CBD / L1-RSRP / L1-SINR measurement are in the same time domain unit. In this example, two schemes can be used to determine whether to lift the measurement restriction.

[0208] Solution 1: The frequency domain resources of SSB and CSI-RS belong to the same carrier or different carriers in the same frequency band in the FR2 frequency domain interval.

[0209] In this solution, if the terminal device supports simultaneous reception of SSB and CSI-RS through multiple receive beams (i.e., multi Rx with different QCL type D RSs, that is, the terminal device supports the first capability "simultaneousReceptionDiffTypeD"), and SSB is associated with TCI state 1 and CSI-RS is associated with TCI state 2, where TCI state 1 and TCI state 2 are different, then there is no measurement restriction on SSB for RLM / BFD / CBD / L1-RSRP / L1-SINR measurement and CSI-RS for RLM / BFD / CBD / L1-RSRP / L1-SINR measurement. Otherwise, the terminal device needs to measure one of SSB and CSI-RS, but not both.

[0210] The TCI state 1 may also be baseband processing unit 1, and the TCI state 2 may also be baseband processing unit 2, where baseband processing unit 1 and baseband processing unit 2 are different and independent of each other. The state 1 may also be Rx beam 1, and the TCI state 2 may also be Rx beam 2, where Rx beam 1 and Rx beam 2 are receive beams in different directions.

[0211] In addition, the terminal device can further determine the SCS of SSB and CSI-RS. Specifically, if the terminal device supports simultaneous reception of SSB and CSI-RS through multiple receive beams, and SSB is associated with TCI state 1 / baseband processing unit 1, and CSI-RS is associated with TCI state 2 / baseband processing unit 2, on this basis, if the SCS of SSB and CSI-RS are the same, then the terminal device determines that there is no measurement restriction when measuring SSB and CSI-RS. If the SCS of SSB and CSI-RS are different, when the terminal device supports the ability to process different SCSs, that is, supports the ability indicated by the parameter "simultaneousRxDataSSB-DiffNumerology", the terminal device can determine that there is no measurement restriction when measuring SSB and CSI-RS. Accordingly, when the terminal device does not support the ability indicated by the parameter "simultaneousRxDataSSB-DiffNumerology", the terminal device needs to measure one of SSB and CSI-RS, but not both.

[0212] It should be noted that if SSB and CSI-RS are respectively associated with two independent baseband processing units, that is, the terminal device can process two signals at the same time. In the process of determining whether to lift the measurement restriction, the SCS of SSB and CSI-RS can be further judged. After determining that SSB and CSI-RS are respectively associated with two independent baseband processing units, the measurement restriction of SSB and CSI-RS is directly lifted.

[0213] Solution 2: The frequency domain resources of SSB and CSI-RS belong to different frequency bands in the FR2 frequency domain interval, and the terminal device does not indicate IBM on these two frequency band pairs.

[0214] Similar to Solution 1, in this solution, if the terminal device supports simultaneous reception of SSBs and CSI-RSs through multiple receive beams, and the SSBs are associated with TCI state 1 and the CSI-RSs are associated with TCI state 2, where TCI state 1 and TCI state 2 are different, then there are no measurement restrictions for the SSBs used for RLM / BFD / CBD / L1-RSRP / L1-SINR measurements and the CSI-RS used for RLM / BFD / CBD / L1-RSRP / L1-SINR measurements. Otherwise, the terminal device needs to measure one of the SSBs and CSI-RSs, but not both.

[0215] The TCI state 1 may also be baseband processing unit 1, and the TCI state 2 may also be baseband processing unit 2, where baseband processing unit 1 and baseband processing unit 2 are different and independent of each other. The state 1 may also be Rx beam 1, and the TCI state 2 may also be Rx beam 2, where Rx beam 1 and Rx beam 2 are receive beams in different directions.

[0216] In addition, the terminal device can further determine the SCS of the SSB and CSI-RS. The determination method is similar to that of Solution 1 and will not be repeated here for the sake of brevity.

[0217] In another feasible example, the multiple signals to be received may include a first CSI-RS and a second CSI-RS. The time domain resources of the first CSI-RS used for RLM / BFD / CBD / L1-RSRP / L1-SINR measurement and the second CSI-RS used for RLM / BFD / CBD / L1-RSRP / L1-SINR measurement are in the same time domain unit. At this time, if the terminal device supports simultaneous reception of the first CSI-RS and the second CSI-RS through multiple receive beams, and the first CSI-RS is associated with TCI state 1 and the second CSI-RS is associated with TCI state 2 (TCI state 1 and TCI state 2 are different), then in the following scenarios, there are no measurement restrictions on the first CSI-RS and the second CSI-RS:

[0218] The first CSI-RS resource or the second CSI-RS resource is configured as a repeated resource;

[0219] A first CSI-RS and / or a second CSI-RS is configured in a beam detection parameter set (e.g., q1), and a first CSI-RS and / or second CSI-RS beam failure is detected;

[0220] The type of the QCL information associated with the first CSI-RS and the second CSI-RS is not QCL type D, or the QCL information of the first CSI-RS and the second CSI-RS is unknown information.

[0221] The TCI state 1 may also be baseband processing unit 1, and the TCI state 2 may also be baseband processing unit 2, where baseband processing unit 1 and baseband processing unit 2 are different and independent of each other. The state 1 may also be Rx beam 1, and the TCI state 2 may also be Rx beam 2, where Rx beam 1 and Rx beam 2 are receive beams in different directions.

[0222] The following describes the scheduling restriction scenario in detail.

[0223] Optionally, in some other embodiments, the first scenario is a scenario in which time domain resources of at least one channel to be received overlap with those of at least one signal. Accordingly, in step 210, the terminal device determines that there is no measurement restriction and / or scheduling restriction in the first scenario, including:

[0224] In a case where the terminal device supports the first capability, if the terminal device satisfies a third condition, the terminal device determines that there is no scheduling restriction in the first scenario; the third condition includes at least one of the following:

[0225] The at least one channel to be received and the at least one signal are respectively associated with a plurality of QCL information whose QCL type is type D, and the number of the at least one channel to be received is less than the plurality of receive beams;

[0226] The terminal device supports the capability of simultaneously processing at least one signal and at least one channel with different subcarrier spacings.

[0227] It should be understood that in the embodiment of the present application, the terminal device can use multiple Rx beams to simultaneously measure the reference signal and receive conventional downlink channels (such as PDCCH and PDSCH), avoiding scheduling restrictions on data reception caused by measurement.

[0228] Specifically, the terminal device can perform measurements and receive downlink channels / signals based on the receiving capabilities of multiple Rx beams, and determine whether to impose scheduling restrictions on downlink channels / signals on specific time domain units that will be affected by the measurements.

[0229] Optionally, whether to impose scheduling restrictions on downlink channels / signals can be determined by the number of PDCCH / PDSCH / CSI-RS / TRS resources (e.g., resources) that conflict with reference signals, and the relationship between their QCL type D. Assume that, at the time-domain unit location where the reference signal conflicts, the terminal device needs to receive N PDCCH / PDSCHs associated with different QCL type Ds. If N is less than the number of Rx beams in the terminal device, there are excess Rx beams for measurement, and scheduling restrictions are not required. If N is greater than or equal to the number of Rx beams in the terminal device, scheduling restrictions are required.

[0230] Optionally, whether downlink channels / signals are subject to scheduling restrictions depends not only on the terminal device's ability to simultaneously receive downlink channels / signals via multiple RX beams, but also on its ability to process downlink channels / signals from different SCSs. For example, this is related to the capability indicated by the parameter "simultaneousRxDataSSB-DiffNumerology." If the terminal device supports simultaneous reception of at least one channel and at least one signal, and supports reception of at least one channel and at least one signal from different SCSs, no scheduling restrictions are imposed on downlink data reception. Otherwise, scheduling restrictions are imposed.

[0231] Optionally, frequency domain resources of at least one channel and at least one signal are located in the same frequency band, and subcarrier spacings of each channel and each signal are different;

[0232] or,

[0233] The frequency domain resources of at least one channel and the frequency domain resources of at least one signal are located in different frequency bands, and the terminal device does not support independent beam management capabilities.

[0234] Optionally, the above frequency band may belong to a high frequency band, such as an FR2 frequency band.

[0235] It should be understood that when the frequency domain resources of at least one channel to be received and at least one signal belong to the same frequency band, or when the frequency domain resources of at least one channel to be received and at least one signal belong to different FR2 frequency bands, and the terminal device does not support IBM capability, if the at least one channel to be received and the at least one signal are respectively associated with multiple QCL information of type D, and the number of at least one channel to be received is less than the multiple receiving beams; and / or the terminal device supports the ability to simultaneously process at least one signal and at least one channel with different subcarrier spacings, then the terminal device can perform scheduling restrictions.

[0236] Optionally, when the terminal device supports the first capability, if the terminal device does not meet the third condition, the terminal device determines not to receive or send in the first time domain unit, and at least one time domain unit before and / or after the first time domain unit; the first time domain unit is a time domain unit in which the time domain resources of the at least one signal to be transmitted and at least one channel overlap.

[0237] Among them, the time domain unit can be a counting unit of the time domain, and the time domain unit can be a time domain symbol (such as an OFDM symbol) or a time domain symbol combination, etc., and the embodiments of the present application do not limit this.

[0238] It is understood that the terminal device is not restricted in scheduling when the third condition is met. Otherwise, scheduling is restricted, and the terminal device may not receive or transmit on the channel in the conflicting time domain unit and the K time domain units before and after it. K is an integer greater than or equal to 1.

[0239] It should be noted that the specific time domain units affected by the measurement can be determined based on actual conditions. For example, in the same-frequency measurement process, if RSRP or SINR is measured, scheduling restrictions need to be placed on the time domain symbol where the SSB is located, and the time domain symbols before and after them. If RSRQ is measured, scheduling restrictions need to be placed on the time domain symbol where the SSB and RSSI measurements are located, and the time domain symbols before and after them.

[0240] For example, when the terminal device supports the capability of simultaneously using Nsim_Rx_beam=2 Rx beams to receive channels and signals, multiple Rx beams in different directions can be used to simultaneously perform measurements and receive conventional downlink channels / reference signals (PDCCH / PDSCH / TRS / CSI-RS, etc.).

[0241] For scheduling restrictions of L1 measurements, no downlink reception scheduling restriction is required regardless of whether the reference signal resource is the same as the currently activated PDCCH / PDSCH TCI state; or the terminal device is restricted from receiving PDCCH / PDSCH associated with two different QCL type Ds, but can still receive PDCCH / PDSCH associated with the same QCL type D or other QCL types.

[0242] Scheduling restrictions for L3 measurements outside the MG or within the NCSG in L3 may include: for a frequency band of FR2, when the reference signal and channel to be received by the terminal device have different SCSs, if the terminal device supports the capabilities indicated by the parameters "simultaneousRx-DiffNumerology" and "simultaneousReceptionDiffTypeD", the terminal device determines that there is no measurement restriction; otherwise, if the terminal device does not support the capabilities indicated by the parameters "simultaneousRx-DiffNumerology" and "simultaneousReceptionDiffTypeD", it is determined that the channel cannot be received or transmitted on the conflicting time domain unit and the K time domain units before and after.

[0243] In addition, for a frequency band combination of FR2, if the terminal device does not support IBM capabilities on these frequency bands, but supports the capability indicated by the parameter "imultaneousReceptionDiffTypeD", and the SSB and CSI-RS / data have the same SCS, then the terminal device can determine that no scheduling restrictions are imposed. In addition, when the SSB and CSI-RS / data have different SCSs, if the terminal device supports the capability indicated by the parameter "simultaneousRx-DiffNumerology", the terminal device can also determine that no scheduling restrictions are imposed. Otherwise, if the terminal device supports IBM capabilities on these frequency bands, the terminal device also does not impose scheduling restrictions.

[0244] In summary, when measuring at high frequencies such as the FR2 band, it is necessary to traverse all Rx beam directions to obtain the final measurement results. When a terminal device has the ability to use multiple Rx beams simultaneously, this solution can reduce measurement and transmission time and improve efficiency by leveraging this capability to remove measurement and / or scheduling restrictions.

[0245] In addition, the embodiments of the present application also provide a terminal device that needs to meet measurement restrictions and scheduling restrictions on downlink channels / signals during measurement when supporting multiple Rx beams for measurement and / or channel reception; at the same time, it clarifies the terminal device's capability reporting and network configuration methods, and formulates corresponding behaviors for different terminal devices to meet the terminal production and certification requirements of different terminal device capabilities.
