If the value of the field (multiRx-PrefernceFR2-r18) in the UEAssitanceInformation IE is not Single or is Null, the first information may be considered to indicate that the third capability is not desired to be activated. For example, the third capability may be the ability of the UE to perform downlink reception using a single antenna panel.

[0152] In some embodiments, the UE has multiple activated first transmission configuration indication TCI states, including but not limited to at least one of the following: the UE currently has multiple activated first TCI states;

[0153] The UE receives an activation instruction to activate multiple first TCI states;

[0154] The UE determines to activate multiple first TCI states according to its own transmission requirements.

[0155] In some embodiments, the first TCI state indicates a downlink transmit beam of the network device, or the first TCI state indicates an uplink transmit beam of the UE.

[0156] In this case, if the UE has multiple first TCI states activated, it can be considered that the first condition is met.

[0157] In some embodiments, when the UE has activated multiple first TCI states, it is also necessary to see whether the layer 1 measurement report sent by the UE to the network device includes multiple first TCI states or beam information corresponding to multiple first TCI states.

[0158] For example, assuming that the first TCI state is a downlink receive beam of the network device, the Layer 1 measurement report sent by the UE to the network device includes multiple third TCI states or beam identifiers corresponding to multiple third TCI states. The third TCI state may be the first TCI state itself or a TCI state of a beam quasi-co-located with the beam indicated by the first TCI state. The aforementioned beam information may include a beam identifier, a third TCI state indicating the beam, or beam direction information.

[0159] In some embodiments, the first configuration may instruct the UE to send layer 1 measurement reports to the network device based on the group, and the UE will subsequently send layer 1 measurement reports to the network device based on the group. If the UE receives the first configuration, it means that the network device wants the UE to perform multiple downlink receptions simultaneously or activate the first capability.

[0160] In some embodiments, if the UE has sent a group-based layer 1 measurement report to the network device, the layer 1 measurement report includes layer 1 measurement results of two or more beams.

[0161] S2103: The UE sends second information to the network device.

[0162] In some embodiments, second information is sent to the network device based on the result of whether the first capability is activated.

[0163] In some embodiments, the second information indicates whether the UE has activated the first capability.

[0164] In some embodiments, the UE sends an RRC message, MAC CE, or UCI and other information containing the second information to the network device.

[0165] In some embodiments, step S2103 is optional. For example, if the UE has already sent the first message to the network device, the UE does not need to send the second message. In other embodiments, after activating the first capability, the UE can automatically detect the secondary cell and establish a connection with the other cell by exchanging information with the current serving cell, thereby adding a secondary cell for the UE.

[0166] In some embodiments, S2103 is an optional step, for example, the UE does not need to send the second information to the network device.

[0167] If the UE reports the second information to the network device, the network device may subsequently perform transmission scheduling of the multi-antenna panel for the UE according to the second information.

[0168] Exemplarily, if the second information indicates that the UE activates the first capability, the network device may relax transmission scheduling for the UE.

[0169] By way of example, if the UE activates the first capability, the UE may relax restrictions and / or relaxation on layer 1 measurements.

[0170] In summary, in some embodiments, when the UE activates the first capability, it determines whether to remove the restriction of the corresponding operation based on whether the corresponding condition is met. The corresponding operation includes but is not limited to scheduling restriction, layer 1 measurement restriction, etc.

[0171] Exemplarily, when the UE activates the first capability and satisfies at least one of the following conditions, the UE may perform layer 1 measurement without restriction:

[0172] The CSI-RS used for L1-RSRP measurement and other CSI-RS are configured in the CSI-RS resource set for repeated transmission. Other CSI-RS may be used for, but not limited to, radio link monitoring (RLM), beam failure detection (BFD), and candidate beam detection (CBD).

[0173] The two activated TCI states for the two PDSCHs have already reported L1-RSRP to the network device based on group reporting;

[0174] The two TCI states reported based on the group are quasi-co-located with the activated TCI state of the PDSCH.

[0175] Layer 1-Reference Signal Received Power (L1-RSRP).

[0176] Exemplarily, when the UE activates the first capability and satisfies at least one of the following conditions, the UE may perform measurement relaxation without restriction:

[0177] The CSI-RS used for L1-RSRP measurement and other CSI-RS are configured in the CSI-RS resource set for repeated transmission. Other CSI-RS may be used for, but not limited to, radio link monitoring (RLM), beam failure detection (BFD), and candidate beam detection (CBD).

[0178] The two activated TCI states for the two PDSCHs have already reported L1-RSRP to the network device based on group reporting;

[0179] The two TCI states reported based on the group are quasi-co-located with the activated TCI state of the PDSCH.

[0180] In some embodiments, performing measurement relaxation may include increasing a measurement period, a detection period, or an evaluation period of layer 1 and / or layer 3 of the cell.

[0181] In some embodiments, performing measurement relaxation may include: suspending layer 1 and / or layer 3 measurement of a corresponding cell for a period of time. Exemplarily, the corresponding cell may include but is not limited to a secondary cell.

[0182] For FR2-1, the CSI-RS used for L1-RSRP measurement and other CSI-RS are configured in the CSI-RS resource set for repeated transmission. Other CSI-RS may include, but are not limited to, those used for Radio Link Monitoring (RLM), Beam Failure Detection (BFD), Condition Beam Detection (CBD), and Layer 1 measurement of the primary cell. The UE supports the first capability and should be able to perform Layer 1 measurement without restriction:

[0183] The CSI-RS used for L1-RSRP measurement and other CSI-RS are configured in the CSI-RS resource set for repeated transmission. Other CSI-RS may be used for, but not limited to, radio link monitoring (RLM), beam failure detection (BFD), and candidate beam detection (CBD).

[0184] The two activated TCI states for the two PDSCHs have already reported L1-RSRP to the network device based on group reporting;

[0185] The two TCI states reported based on the group are quasi-co-located with the activated TCI state of the PDSCH;

[0186] The UE has activated the first capability.

[0187] As shown in FIG2B , an embodiment of the present disclosure provides an information processing method, which is performed by the communication system shown in FIG1A . The method includes:

[0188] S2201: The UE determines whether the UE supports the first capability.

[0189] In some embodiments, the UE supports the first capability including at least one of the following:

[0197] Downlink data of the physical downlink shared channel PDSCH;

[0199] In some embodiments, the UE has multiple antenna panels and the UE has a second capability, and then it is determined whether the UE has the first capability. In this case, the second capability may serve as a prerequisite capability for determining whether the UE has the first capability.

[0200] In some embodiments, if the UE does not have the second capability, it can be directly determined that the UE does not have the first capability.

[0201] In some other embodiments, the UE has multiple antenna panels but does not have the second capability, and it can be determined that the UE does not have the first capability.

[0202] In some embodiments, the UE has multiple antenna panels and the UE has the second capability, and it may be determined that the UE has the first capability.

[0203] In some embodiments, the UE has multiple antenna panels and the UE has a second capability, and whether the UE has the first capability is determined based on whether the second capability is activated.

[0204] In some embodiments, the UE has multiple antenna panels and the second capability of the UE is activated, and it is determined that the UE has the first capability.

[0205] In some embodiments, the UE has multiple antenna panels and the second capability of the UE is not activated, and it is determined that the UE does not have the first capability.

[0207] The UE supports group-based layer 1 measurement reporting; a group includes one or more beams;

[0208] The UE supports downlink reception scheduling of multiple nodes;

[0210] In some embodiments, the UE's support for group-based Layer 1 measurement reporting can be understood as the UE's support for reporting Layer 1 measurement results for a beam group at one time. A beam group may include one or more beams. In some embodiments, a beam group may include at least two beams.

[0211] S2202: The UE supports the first capability, and the UE determines whether to perform beam fast scanning.

[0212] In some embodiments, when the UE performs fast beam scanning, the UE can simultaneously receive the same reference signal in different directions, thereby shortening the scanning of multiple beams in different beam directions within a cell.

[0213] Exemplarily, since the UE supports the first capability, that is, the UE supports beam scanning in N directions greater than or equal to 2 at the same time, the scanning time can be shortened to 1 / N relative to beam scanning on a single antenna panel.

[0214] In some embodiments, the UE supports a first capability and meets a second condition, and it is determined that the UE performs beam fast scanning.

[0215] In some embodiments, the UE supports a first capability and the UE does not meet a second condition, and determines that the UE does not perform beam fast scanning.

[0222] In some embodiments, the second condition may further include the first condition. For example, when the first condition is met, it may be considered that the second condition is also met.

[0223] In some embodiments, the UE supports fast beam scanning, which means that the UE can support two or more beam detections (or scanning) at a time point.

[0224] In some embodiments, the UE's beam measurement accuracy in a single beam direction meeting the accuracy requirement is a prerequisite for the UE to perform beam scanning. If the UE's beam measurement accuracy in a unicast beam direction does not meet the accuracy requirement, the UE should configure antenna panel parameters to ensure sufficient beam quality in at least a single beam direction to ensure single-beam communication quality.

[0228] In some embodiments, the first TCI state indicates a downlink transmit beam of the network device, or the first TCI state indicates an uplink transmit beam of the UE.

[0229] In this case, if the UE has multiple first TCI states activated, it can be considered that the first condition is met.

[0230] In some embodiments, when the UE has activated multiple first TCI states, it is also necessary to see whether the layer 1 measurement report sent by the UE to the network device includes multiple first TCI states or beam information corresponding to multiple first TCI states.

[0231] For example, assuming that the first TCI state is a downlink receive beam of the network device, the Layer 1 measurement report sent by the UE to the network device includes multiple third TCI states or beam identifiers corresponding to multiple third TCI states. The third TCI state may be the first TCI state itself or a TCI state of a beam quasi-co-located with the beam indicated by the first TCI state. The aforementioned beam information may include a beam identifier, a third TCI state indicating the beam, or beam direction information.

[0232] In some embodiments, the first configuration may instruct the UE to send layer 1 measurement reports to the network device based on the group, and the UE will subsequently send layer 1 measurement reports to the network device based on the group. If the UE receives the first configuration, it means that the network device wants the UE to perform multiple downlink receptions simultaneously or activate the first capability.

[0233] In some embodiments, if the UE has sent a group-based layer 1 measurement report to the network device, the layer 1 measurement report includes layer 1 measurement results of two or more beams.

[0234] S2203: The UE sends third information to the network device.

[0235] In some embodiments, third information is sent to the network device based on the result of whether the first capability is activated.

[0236] In some embodiments, the third information indicates whether the UE has activated the first capability.

[0237] In some embodiments, the UE sends an RRC message, MAC CE, or UCI and other information containing the third information to the network device.

[0238] In some embodiments, step S2103 is optional. For example, if the UE has already sent the first information to the network device, the UE does not need to send the third information to the network device. In other embodiments, the UE does not need to send the third information to the network device. If the UE sends the third information to the network device, the network configuration can be sent down to enable the UE to simultaneously scan multiple secondary cells or multiple beams of a secondary cell using a fast scanning capability.

[0288] S3203: Send the third information.

[0289] It is worth noting that for the optional implementation of S3203 , reference may be made to any optional implementation of S2203 in FIG. 2B .

[0290] As shown in FIG3C , an embodiment of the present disclosure provides an information processing method, which is executed by a network device. The method may include:

[0291] S3301: Receive first information.

[0292] In some embodiments, the network device receives first information sent by the UE, wherein the first information indicates that the third capability is not desired to be activated, or the first information indicates that the first capability is desired to be activated.

[0293] In some embodiments, the UE activates a third capability, and the UE performs downlink reception using a single antenna panel.

[0294] The first capability includes at least one of the following:

[0295] The UE supports measurement of reference signals and reception of downlink data;

[0296] The UE supports simultaneous measurement of different reference signals.

[0297] In some embodiments, the first capability, the third capability, and descriptions related to the first capability can all refer to the embodiments corresponding to Figure 2A and / or Figure 2B.

[0298] In some embodiments, the network device may further perform receiving the second information and / or the third information.

[0299] In some embodiments, the second information indicates whether the UE has activated the first capability.

[0300] In some embodiments, the UE sends an RRC message, MAC CE, or UCI and other information containing the second information to the network device.

[0301] Receiving the second information is an optional step. For example, if the network device has received the first information, the second information may not be received.

[0302] If the network device receives the second information, the network device may subsequently perform transmission scheduling of the multi-antenna panel for the UE according to the second information.

[0303] Exemplarily, if the second information indicates that the UE activates the first capability, the network device may relax transmission scheduling for the UE.

[0304] By way of example, if the UE activates the first capability, the UE may relax restrictions and / or relaxation on layer 1 measurements.

[0305] In summary, in some embodiments, when the UE activates the first capability, it determines whether to remove the restriction of the corresponding operation based on whether the corresponding condition is met. The corresponding operation includes but is not limited to scheduling restriction, layer 1 measurement restriction, etc.

[0306] Exemplarily, when the UE activates the first capability and satisfies at least one of the following conditions, the UE may perform layer 1 measurement without restriction:

[0307] The CSI-RS used for L1-RSRP measurement and other CSI-RS are configured in the CSI-RS resource set for repeated transmission. Other CSI-RS may be used for, but not limited to, radio link monitoring (RLM), beam failure detection (BFD), and candidate beam detection (CBD).

[0308] The two activated TCI states for the two PDSCHs have already reported L1-RSRP to the network device based on group reporting;

[0309] The two TCI states reported based on the group are quasi-co-located with the activated TCI state of the PDSCH.

[0310] Layer 1-Reference Signal Received Power (L1-RSRP).

[0311] Exemplarily, when the UE activates the first capability and satisfies at least one of the following conditions, the UE may perform measurement relaxation without restriction:

[0312] The CSI-RS used for L1-RSRP measurement and other CSI-RS are configured in the CSI-RS resource set for repeated transmission. Other CSI-RS may be used for, but not limited to, radio link monitoring (RLM), beam failure detection (BFD), and candidate beam detection (CBD).

[0313] The two activated TCI states for the two PDSCHs have already reported L1-RSRP to the network device based on group reporting;

[0314] The two TCI states reported based on the group are quasi-co-located with the activated TCI state of the PDSCH.

[0315] In some embodiments, performing measurement relaxation may include increasing a measurement period, a detection period, or an evaluation period of layer 1 and / or layer 3 of the cell.

[0316] In some embodiments, performing measurement relaxation may include: suspending layer 1 and / or layer 3 measurement of a corresponding cell for a period of time. Exemplarily, the corresponding cell may include but is not limited to a secondary cell.

[0317] For FR2-1, the CSI-RS used for L1-RSRP measurement and other CSI-RS are configured in the CSI-RS resource set for repeated transmission. Other CSI-RS may include, but are not limited to, those used for Radio Link Monitoring (RLM), Beam Failure Detection (BFD), Condition Beam Detection (CBD), and Layer 1 measurement of the primary cell. The UE supports the first capability and should be able to perform Layer 1 measurement without restriction:

[0318] The CSI-RS used for L1-RSRP measurement and other CSI-RS are configured in the CSI-RS resource set for repeated transmission. Other CSI-RS may be used for, but not limited to, radio link monitoring (RLM), beam failure detection (BFD), and candidate beam detection (CBD).

[0319] The two activated TCI states for the two PDSCHs have already reported L1-RSRP to the network device based on group reporting;

[0320] The two TCI states reported based on the group are quasi-co-located with the activated TCI state of the PDSCH;

[0321] The UE has activated the first capability.

[0322] In some embodiments, the third information indicates whether the UE has activated the first capability.

[0323] In some embodiments, an RRC message, MAC CE, or UCI, etc., carrying the third information, sent by the UE is received. Similarly, receiving the third information is an optional step.

[0324] In the case of multiple transmit / receive points (mTRP), if the UE has multiple beams, it can simultaneously receive two signals from two TRPs. These two signals can be a combination of data and data, a combination of reference signals and data, or a combination of reference signals and reference signals. For the combination of data and data, the UE first needs to perform L1-RSRP measurements on both TRPs and select the optimal beam pair. The network (NW) then configures two TCI states corresponding to the two TCI states.

[0325] For L1-RSRP measurement in mTRP with multi-RXRX reception, it may include but is not limited to at least one of the following: measurement period, scheduling restriction, and measurement restriction.

[0326] These limitations will be related to UE capabilities and behavior for multiple RX reception.

[0327] The current measurement period for L1-RSRP measurement is defined in Table 1 below:

[0328] Table 1

[0329] If a higher layer parameter (timeRestrictionForChannelMeasurement) is configured, then M=1, otherwise M=3.

[0330] If the UE supports fast beam scanning and has activated multiple reception (RX) operations, N is equal to the reduced number of beams (reducedRxBeamNum), otherwise N=8.

[0331] For FR2-1, when the CSI-RS used for L1-RSRP measurement on the PCell is in the same OFDM symbol as the CSI-RS used for RLM, BFD, CBD or L1-RSRP measurement on the PCell, a UE supporting multi-RX operation shall be able to measure the CSI-RS for L1-RSRP measurement without restriction if the following conditions are met:

[0332] The CSI-RS of L1-RSRP and other CSI-RS are not in any CSI-RS resource set configured with duplication, and the activated TCI state resources of 2 PDSCHs have been reported as a resource group in the Rel-17 group RSRP report, and the two CSI-RSs and two PDSCHs overlap on the same OFDM symbol, the CSI-RS of L1-RSRP has the same QCL source as the activated TCI state of one [PDSCH], and the other CSI-RS has the same QCL source as the activated TCI state of the other [PDSCH], and if the CSI-RS(s) and PDSCH(s) conditionally overlap on the same OFDM symbol(s).

[0333] A new capability of the UE is defined. The newly defined capability may be at least one of the following:

[0334] This capability includes at least one of the following:

[0335] Capability 1.1: The UE supports simultaneous reception of RS and data.

[0336] Capability 1.2: The UE receives two reference signals simultaneously.

[0337] When a UE is equipped with multiple panels, a new capability is defined for the UE: it can support simultaneous reception of PDCCH and / or PDSCH and RS measurements for L1 measurements. The beams used by the PDCCH and / or PDSCH are quasi-co-located with the beams used for L1 reference signals. This quasi-co-location is based on Type D quasi-co-location. This supports simultaneous measurement of L1 values ​​from two RSs with different QCL Types (d) that overlap in time.

[0338] The prerequisites for the UE to have new capabilities include but are not limited to at least one of the following:

[0339] Option A: Quasi-co-location based on different types of D can simultaneously receive multiple downlinks;

[0340] Option B: Group-based L1-RSRP reporting capability;

[0341] Option C: Multi-TRP capability based on multiple DCI. Multiple DCI is a multi-TRP scenario. Multi-TRP capability is the ability of the UE to communicate with multiple TRPs.

[0342] Option D: Space division multiplexing (SDM) capability based on a single DCI.

[0343] The prerequisites can be a combination or a subset of the above options.

[0344] Fast beam scanning capabilities are related to multi-panel reception. For example, if a UE supports multi-panel reception, it can measure an RS from two directions simultaneously. This reduces the total time to cover the entire spatial domain.

[0345] Candidate values ​​for the beam scanning factor: {2, 4, 6} for FR2-1. For example, the candidate values ​​for the beam scanning factor may indicate the number of beams the UE needs to scan. For another example, the candidate values ​​for the beam scanning factor may indicate the number of beams the UE scans at once when performing a beam start scan.

[0346] Table 2

[0347] The types in Table 2 may relate to the granularity (level) of the characteristic. For example, the characteristic may be UE-level, UE-band-level, UE-band-combination-level, or some other undefined granularity.
