[0157] In current wireless communication systems, the UE needs to perform multiple tasks in order to monitor link quality and maintain good data transmission:

[0158] Radio Link Detection (RLM):

[0159] Radio Link Monitoring (RLM) is a critical component in wireless communication systems, designed to ensure the reliability and quality of wireless links. Its main function is to continuously monitor the performance of the wireless link between a base station and a mobile station, or between two base stations. RLM determines the health status of the link by evaluating various parameters such as signal strength, signal-to-noise ratio (SNR), and bit error rate (BER).

[0160] L1-RSRP: Layer 1-Reference Signal Received Power (L1-RSRP) is a key metric used in beam management of wireless communication systems, especially 5G networks. It provides a measure of the power level of the reference signal received from the base station, which is crucial for determining the quality of different beams.

[0161] Beam Failure Detection (BFD): Beam Failure Detection (BFD) is a key feature in 5G networks that can quickly identify and recover from interruptions in the wireless link, especially in high-frequency bands. It monitors reference signals and triggers recovery when a beam failure is detected, ensuring seamless communication and maintaining link stability.

[0162] Candidate beam detection plays a crucial role in 5G networks by identifying potential beams that can be used for communication between base stations and user equipment. This process is essential for optimizing beam management, especially in millimeter-wave (mmWave) communication where beams are narrow and highly directional. By detecting candidate beams, the system can efficiently allocate resources and maintain high-quality connections, thereby reducing overhead and improving network performance.

[0163] The NW will configure the UE to perform multiple L1 measurement tasks on multiple cells. Additionally, the UE may need to perform measurements on multiple CCs (Component Carriers). On each CC, there will also be multiple neighboring cells and TRPs (Transmission / Reception Points).

[0164] In traditional 5G systems, the RS (Reference Signal) can be configured for different L1 measurement purposes, such as:

[0165] L1-RSRP measurement;

[0166] RLM;

[0167] Beam Fault Detection (BFD);

[0168] Candidate Beam Detection (CBD);

[0169] L1-SINR (L1-Signal to Interference plus Noise Ratio).

[0170] In some embodiments, L1 measurements can be configured for different cells. These cells include:

[0171] Serving the community;

[0172] MIMO (Multiple Input Multiple Output) cells or TRPs;

[0173] Moving neighboring communities.

[0174] In summary, all L1 measurement tasks that the UE needs to perform on multiple cells can be shown in Figure 1b.

[0175] As shown in Figure 1b, the L1 measurement task will be processed separately, and many of these tasks cannot be processed simultaneously.

[0176] For example, when RS overlaps in the same time slot, a shared factor is defined for the same measurements in the two cells.

[0177] Taking LTM (L1 / L2-triggered Mobility) as an example, PL1_sharing is designed for SSB (Synchronization Signal Block, PSS / SSS PBCH Block) measurements in the serving cell and neighboring cells.

[0178] PL1_sharing is defined as follows: when the number of neighboring cells configured with SSB-based L1-RSRP measurements is 1, if any symbols from the serving cell and neighboring cells overlap or are adjacent (in the time domain), then P L1_sharing =2. Otherwise, P L1_sharing =1.

[0179] When the number of neighboring cells configured with SSB-based L1-RSRP measurements is greater than 1, and the TCI states of intra-frequency neighboring cells or inter-frequency neighboring cells without gaps are not in the active TCI state list, P L1_sharing =3*N Neighbor_Cell , where N Neighbor_Cel l is the number of neighboring cells whose TCI state is not in the list of active TCI states (used for gapless measurements within and between frequencies). Otherwise, P L1_sharing= 3 * NNEighbor_Cell_in_list, where NNEighbor_Coll_in_list is the number of neighboring cells (including intra-frequency neighboring cells and inter-frequency gapless neighboring cells) whose TCI status is in the active TCI status list. No requirements are defined for any other cells whose TCI status is not in the active TCI status list.

[0180] Taking the L1 measurement for MIMO between a serving cell and another cell as an example, a P-factor is designed to account for the overlap between different cells.

[0181] If SSB resources from cells with different Physical Cell Identifiers (PCIs) are configured for L1-RSRP measurements, and P2 is valid, and any SSB symbols from the serving cell and cells with different PCIs are overlapping or adjacent (in the time domain), then:

[0182] If P1*T SSB <P2*T SSB_CDP .

[0183] P = P1, if P1 * T SSB >P2*T SSB_CDP .

[0184] P = 2 * P1, if P1 * T SSB =P2*T SSB_CDP .

[0185] Where P1 is the time sharing factor between L1 and L3 measurements in the serving cell, and P2 is the time sharing factor between L1 and L3 measurements in different PCI cells; T SSB To serve the SSB cycle of the community, T SSB_CDP For SSB cycles of cells with different PCI.

[0186] Furthermore, measurement limitations are defined for certain situations, but there are no requirements if certain tasks conflict in the time domain. This will significantly degrade the performance of 5G systems.

[0187] For example, due to limited capacity, when the SSBs of neighboring cells and the serving cell overlap in the same CC or different CCs, the UE cannot perform simultaneous processing of RLM and L1-RSRP. Measurement limitations are defined.

[0188] For FR2, for both UEs without [capability of measurement with RTD>CP] and UEs with [capability of measurement with RTD>CP], when an SSB used for L1-RSRP measurement on one CC completely or partially overlaps with OFDM symbols transmitted from the serving cell (or multiple serving cells) on different CCs in the same CC or the same frequency band for RLM, BFD, or CBD measurement, the UE needs to measure one of the SSBs, not both. The measurement period for [SSB-based RLM / SSB-based L1-RSRP] is expected to be longer, and no requirements are defined.

[0189] For FR2, when an SSB used for L1-RSRP measurement on one CC and an SSB used for BFD or CBD measurement on a different CC from a cell with additional PCI on the same CC or in the same frequency band are in the same OFDM symbol, the UE needs to measure one of the SSBs instead of both. The measurement period for SSB-based L1-RSRP measurements is expected to be longer, and there are no defined requirements.

[0190] Because existing communication systems contain multiple L1 measurement tasks that cannot be performed simultaneously, executing multiple L1 measurements can negatively impact system performance, leading to issues such as longer measurement durations and / or measurement limitations. To address this, this disclosure proposes a communication method that defines a terminal with the ability to simultaneously execute multiple L1 measurement tasks, thereby improving system performance by, for example, shortening measurement durations and relaxing measurement limitations.

[0191] Based on the aforementioned wireless communication system, various embodiments of the communication method proposed in this disclosure will be described in detail below.

[0192] Figure 2 is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2, the communication method is used in a communication system 100, and the method includes:

[0193] S201, The terminal sends the first information to the network device.

[0194] In some embodiments, the first information includes the terminal's capability information.

[0195] In some embodiments, the terminal's capability information is used to indicate that the terminal has the capability associated with performing at least two Layer 1 (L1) measurement tasks. Optionally, the terminal's capability is associated with performing multiple L1 measurement tasks. In embodiments of this disclosure, "multiple" can be understood as two or more.

[0196] It should be noted that, in the embodiments of this disclosure, the L1 measurement task can also be described as an L1 measurement operation, an L1 measurement process, etc., and this disclosure does not limit it in this way.

[0197] In some embodiments, the terminal's capability information may include at least one of the following:

[0198] First capability information is used to indicate that the terminal has the ability to perform at least two L1 measurement tasks based on the same reference signal on a single carrier;

[0199] The second capability information is used to indicate that the terminal has the ability to perform the same L1 measurement task based on at least two reference signals on a single carrier.

[0200] The third capability information is used to indicate that the terminal has the ability to perform different L1 measurement tasks based on at least two reference signals on a single carrier.

[0201] The fourth capability information is used to indicate that the terminal has the ability to perform the same or different L1 measurement tasks based on at least two reference signals on multiple carriers.

[0202] In some embodiments, the terminal's capability information can be first capability information, in which case the terminal's capability is related to performing multiple L1 measurement tasks based on a single reference signal on a single carrier. Optionally, the terminal has the capability to perform multiple L1 measurement tasks based on a single reference signal RS on a single carrier.

[0203] In some embodiments, the terminal's capability information can be first capability information, indicating that the terminal has the capability to support different L1 measurement tasks of a cell on a CC. Optionally, the terminal can perform multiple L1 measurement tasks based on the same RS of a cell on a CC. For example, if the terminal's first capability information indicates that the terminal's capability is multi-tasking capability, such as {L1-RSRP, BFD}, then the terminal can simultaneously perform L1-RSRP measurement and BFD measurement based on the same RS.

[0204] In some embodiments, the terminal's capability information can be second capability information, in which case the terminal's capability is related to performing the same L1 measurement task based on at least two reference signals on a single carrier. Optionally, the terminal has the capability to perform the same L1 measurement task based on multiple reference signals on a single carrier.

[0205] In some embodiments, the terminal's capability information can be second capability information, in which case the terminal has the capability to support the same L1 measurement task in different cells on a CC. Optionally, the terminal can perform the same L1 measurement task based on the RS of different cells on a CC (the RS of different cells overlap in the same time unit (e.g., time slot)).

[0206] For example, if the terminal's second capability information indicates that the terminal's capability is a multi-tasking capability, such as: {RS for L1-RSRP of cell 1, RS for L1-RSRP of cell 2}, then the terminal can simultaneously perform L1-RSRP measurements of cell 1 and cell 2 based on the RS.

[0207] In some embodiments, the terminal's capability information can be third capability information, in which case the terminal's capability is related to performing different L1 measurement tasks based on at least two reference signals on a single carrier. Optionally, the terminal has the capability to perform different L1 measurement tasks based on multiple reference signals on a single carrier.

[0208] In some embodiments, the terminal's capability information can be third capability information, thus enabling the terminal to support different L1 measurement tasks for different cells on a single CC. Optionally, the terminal can perform different L1 measurement tasks based on the RS of different cells on a single CC (where the RS of different cells overlap within the same time unit (e.g., time slot)).

[0209] For example, if the terminal's third capability information indicates that the terminal's capability is a multi-tasking capability, such as: {RS for L1-RSRP of cell 1, RS for BFD of cell 2}, then the terminal can simultaneously perform L1-RSRP measurement of cell 1 and BFD measurement of cell 2 based on the RS.

[0210] In some embodiments, the terminal's capability information may be fourth capability information, in which case the terminal's capability is related to performing the same or different L1 measurement tasks based on at least two reference signals on multiple carriers. Optionally, the terminal has the capability to perform the same or different L1 measurement tasks based on multiple reference signals on multiple carriers.

[0211] In some embodiments, the terminal's capability information can be fourth capability information, in which case the terminal has the capability to support the same or different L1 measurement tasks for different cells on multiple CCs. Optionally, the terminal can perform multiple L1 measurement tasks based on the RS of different cells on multiple CCs (the RS of different cells are on different CCs, and the RS of different cells overlap in the same time unit (e.g., time slot)).

[0212] For example, if the terminal's fourth capability information indicates that the terminal's capability is a multi-tasking capability, such as: {RS (e.g., on CC1) for L1-RSRP of cell 1, RS (e.g., on CC2) for BFD of cell 2}, then the terminal can simultaneously perform L1-RSRP measurement of cell 1 and BFD measurement of cell 2 based on the RS.

[0213] For example, if the terminal's fourth capability information indicates that the terminal's capability is a multi-tasking capability, such as: {RS (e.g., on CC1) for L1-RSRP of cell 1, RS (e.g., on CC2) for L1-RSRP of cell 2}, then the terminal can simultaneously perform L1-RSRP measurement of cell 1 and L1-RSRP measurement of cell 2 based on the RS.

[0214] In some embodiments, at least two reference signals overlap within the same time unit, and the at least two reference signals come from different cells.

[0215] In some embodiments, the time unit may include, but is not limited to, time slots, symbols, subframes, frames, etc. Optionally, the symbol may be an OFDM (Orthogonal Frequency Division Multiplexing) symbol.

[0216] In the above embodiments, the at least two reference signals involved are reference signals from different cells, and these reference signals overlap in the same time unit, for example, overlapping in the same time slot, or overlapping in the same symbol, but not limited to this.

[0217] S202. The terminal performs the L1 measurement task based on the above capability information.

[0218] In some embodiments, the terminal can execute at least two L1 measurement tasks simultaneously.

[0219] In some embodiments, if the terminal's capability information includes the aforementioned second capability information, then step S202 may include:

[0220] Parallel processing is performed on the same L1 measurement task based on at least two reference signals.

[0221] In some embodiments, if the terminal has the capability to perform the same L1 measurement task based on multiple reference signals on a single carrier, then the same L1 measurement task performed based on multiple reference signals on a single carrier can be processed in parallel. Optionally, the multiple reference signals come from different cells, and the reference signals from different cells overlap within the same time unit (e.g., time slot).

[0222] For example, if the terminal's second capability information indicates that the terminal's capability is {RS for L1-RSRP of cell 1, RS for L1-RSRP of cell 2}, then the terminal can process the L1-RSRP measurement of cell 1 and the L1-RSRP measurement of cell 2 performed based on the RS in parallel.

[0223] In some embodiments, the second capability information indicates at least one of the following:

[0224] The number of Transmission Configuration Indicator (TCI) states measured simultaneously within the same time unit;

[0225] The number of angles of arrival (AOAs) measured simultaneously within the same time unit;

[0226] The number of cells measured simultaneously within the same time unit.

[0227] In some embodiments, the terminal's second capability information may indicate the number of Transmission Configuration Indication (TCI) states that the terminal simultaneously measures within the same time unit. Optionally, the terminal's second capability may be the number of TCI states that the terminal supports for simultaneous measurement within the same time unit. For example, if the terminal's capability is {the number of TCI states measured simultaneously is 2}, then the terminal can simultaneously measure two TCI states from two AOA directions of two cells.

[0228] In some embodiments, the terminal's second capability information may indicate the number of angles of arrival (AOAs) that the terminal simultaneously measures within the same time unit. Optionally, the terminal's second capability may be the number of AOAs that the terminal supports for simultaneous measurement within the same time unit. For example, if the terminal's capability is {the number of AOAs measured simultaneously is 2}, then the terminal can simultaneously measure the two AOA directions of two cells.

[0229] In some embodiments, the terminal's second capability information may indicate the number of cells the terminal can simultaneously measure within the same time unit. Optionally, the terminal's second capability may be the number of cells the terminal supports for simultaneous measurement within the same time unit. For example, if the terminal's capability is {the number of cells measured simultaneously is 2}, then the terminal can measure two cells simultaneously.

[0230] In some embodiments, if the terminal's capability information includes the aforementioned first capability information, then step S202 may include:

[0231] Sequential processing is performed on different L1 measurement tasks based on at least two reference signals, wherein each reference signal is used for the execution of at least two L1 measurement tasks.

[0232] In some embodiments, if the terminal has the capability to perform different L1 measurement tasks based on the same reference signal on a single carrier, it can sequentially process different L1 measurement tasks performed based on multiple reference signals on a single carrier. Optionally, the multiple reference signals come from different cells, and the reference signals from different cells overlap within the same time unit (e.g., time slot).

[0233] In some embodiments, the L1 measurement personnel performing the measurements based on different reference signals may be the same or different. Optionally, multiple L1 measurement tasks in cell 1 and cell 2 may be the same or different.

[0234] For example, if the terminal's first capability information indicates that the terminal's capabilities are {RS for L1-RSRP and CBD in cell 1, RS for L1-RSRP and RLM in cell 2}, then the terminal can sequentially process the L1-RSRP and CBD measurements of cell 1, and the L1-RSRP and RLM measurements of cell 2, performed based on the RS. Optionally, the terminal simultaneously measures the L1-RSRP and CBD of cell 1 during time period T1, and simultaneously measures the L1-RSRP and RLM of cell 2 during time period T2. It should be noted that time period T1 can be before or after time period T2, and this embodiment does not limit this.

[0235] In some embodiments, at least two reference signals correspond to N cells. If the synchronization signal blocks (SSBs) for measurement in the N cells overlap, the measurement time for each of the N cells to perform the L1 measurement task is a first duration.

[0236] Optionally, the first duration is determined based on N and the second duration, where the second duration is the available measurement cycle for any cell among the N cells to perform the L1 measurement task, and N is an integer greater than or equal to 2.

[0237] In some embodiments, when sequentially processing different L1 measurement tasks performed based on at least two reference signals, the measurement time for performing an L1 measurement task based on each reference signal can be determined based on the number of at least two measurement signals and the available measurement cycle for performing an L1 measurement task based on any one of the reference signals.

[0238] Optionally, if at least two reference signals correspond to N cells, i.e., N reference signals correspond to N cells, then when the synchronization signal blocks (SSBs) for measurement of the N cells overlap, the measurement time for each of the N cells to perform the L1 measurement task is a first duration, which can be the product of N and a second duration, wherein the second duration can be the available measurement cycle for any cell to perform the L1 measurement task.

[0239] In some embodiments, if the terminal's capability information includes the first capability information and the second capability information mentioned above, then step S202 may include: parallel processing of different L1 measurement tasks performed based on at least two reference signals.

[0240] In some embodiments, if a terminal has the ability to perform different L1 measurement tasks based on the same reference signal on a single carrier, and at the same time has the ability to perform the same L1 measurement task based on multiple reference signals on a single carrier, then the terminal can process different L1 measurement tasks based on at least two reference signals in parallel.

[0241] For example, if the terminal's capability information indicates that the terminal's capability is {RS for L1-RSRP and CBD in cell 1, RS for L1-RSRP and CBD in cell 2}, where the RS for cell 1 and the RS for cell 2 are located on the same CC, and the two RS overlap in the same time unit (e.g., time slot), then: the terminal can process in parallel the L1-RSRP and CBD measurements of cell 1 and the L1-RSRP and CBD measurements of cell 2 performed based on the RS.

[0242] In some embodiments, if the terminal's capability information includes the aforementioned third capability information, then step S202 may include: parallel processing of different L1 measurement tasks performed based on at least two reference signals.

[0243] In some embodiments, if the terminal has the capability to perform different L1 measurement tasks based on multiple reference signals on a single carrier, it can process different L1 measurement tasks based on at least two reference signals in parallel.

[0244] For example, if the terminal's third capability information indicates that the terminal's capability is {RS for L1-RSRP of cell 1, RS for BFD of cell 2}, then the terminal can process the L1-RSRP measurement of cell 1 and the BFD measurement of cell 2 performed based on the RS in parallel.

[0245] In some embodiments, the measurement time for performing L1 measurement tasks on at least two cells corresponding to at least two reference signals is a second duration.

[0246] Optionally, the second duration is the available measurement cycle for performing the L1 measurement task in any of the at least two cells.

[0247] In some embodiments, when processing different L1 measurement tasks performed based on at least two reference signals in parallel, the measurement time for performing an L1 measurement task based on each reference signal can be determined by the available measurement cycle for performing an L1 measurement task based on any one reference signal.

[0248] Optionally, if at least two reference signals correspond to N cells, i.e., N reference signals correspond to N cells, then when the synchronization signal blocks (SSBs) for measurement of the N cells overlap, the measurement time for each of the N cells to perform the L1 measurement task is the second duration, where the second duration can be the available measurement cycle for any cell to perform the L1 measurement task.

[0249] In some embodiments, measurement restrictions are relaxed between at least two cells corresponding to at least two reference signals.

[0250] Optionally, the measurement restriction relaxation includes: if the SSBs for different L1 measurement tasks of at least two cells on the same carrier overlap in the same time unit, then the different L1 measurement tasks of at least two cells are measured simultaneously; or, the different L1 measurement tasks of at least two cells are measured using time division multiplexing.

[0251] In some embodiments, if the terminal's capabilities include the capabilities corresponding to the first capability information, the second capability information, or the third capability information, then: if the SSBs for different L1 measurement tasks of at least two cells overlap in the same time unit on the same carrier, then the different L1 measurement tasks of at least two cells are measured simultaneously; or, the different L1 measurement tasks of at least two cells are measured using time division multiplexing.

[0252] In some embodiments, if the terminal's capability information includes the aforementioned fourth capability information, then step S202 may include:

[0253] Based on at least two reference signals overlapping in the same time unit on multiple carriers, the same or different L1 measurement tasks are performed simultaneously.

[0254] In some embodiments, if the terminal has the capability to perform the same or different L1 measurement tasks based on multiple reference signals on multiple carriers, it can simultaneously perform the same or different L1 measurement tasks based on at least two reference signals that overlap in the same time unit on multiple carriers.

[0255] For example, if the terminal's fourth capability information indicates that the terminal's capability is {RS (e.g., on CC1) for L1-RSRP of cell 1, RS (e.g., on CC2) for BFD of cell 2}, then the terminal can simultaneously perform L1-RSRP measurement of cell 1 and BFD measurement of cell 2 based on the RS.

[0256] For example, if the terminal's fourth capability information indicates that the terminal's capability is {RS (e.g., on CC1) for L1-RSRP of cell 1, RS (e.g., on CC2) for L1-RSRP of cell 2}, then the terminal can simultaneously perform L1-RSRP measurement of cell 1 and L1-RSRP measurement of cell 2 based on the RS.

[0257] In some embodiments, measurement restrictions between multiple carriers are relaxed.

[0258] Optionally, the measurement restriction relaxation includes: if SSBs for different L1 measurement tasks of at least two cells on the same carrier overlap in the same time unit, then different L1 measurement tasks on different carriers are measured simultaneously; or, different L1 measurement tasks on different carriers are measured using time division multiplexing.

[0259] In some embodiments, if the terminal's capabilities include the capabilities corresponding to the fourth capability information mentioned above, then: if the SSBs for different L1 measurement tasks of at least two cells on the same carrier overlap in the same time unit, then different L1 measurement tasks on different carriers are measured simultaneously; or, different L1 measurement tasks on different carriers are measured using time division multiplexing.

[0351] In some embodiments, the above methods may include the methods described in the embodiments of the communication system side, terminal side, network equipment side, core network equipment side, etc., which will not be repeated here.

[0352] This disclosure also provides an alternative implementation in which the ability of the UE to perform multiple measurement tasks in L1 measurements is defined.

[0353] In some embodiments, measurements are performed for different cells with different L1 measurement tasks.

[0354] In some embodiments, RS can be configured for different L1 measurement tasks.

[0355] In some embodiments, L1 measurements can be configured for different cells.

[0356] In some embodiments, different L1 measurement tasks in different cells may include, but are not limited to, the following:

[0357] Case 1: {RS is used for L1-RSRP in cell 1, and RS is used for L1-RSRP in cell 2};

[0358] Case 2: {RS is used for L1-RSRP in cell 1, and RS is used for RLM in cell 2};

[0359] Case 3: {RS is used for L1-RSRP in cell 1, and RS is used for BFD in cell 2};

[0360] Case 4: {RS is used for L1-RSRP in cell 1, and RS is used for CBD in cell 2};

[0361] Case 5: {RS is used for L1-RSRP in cell 1, and RS is used for L1-SINR in cell 2}.

[0362] In some embodiments, the terminal has UE capability 1, which means that the UE has the ability to support different L1 measurement tasks for a cell.

[0363] In some embodiments, when the UE is configured to perform multiple L1 measurement tasks, the UE can obtain the results of different L1 measurement tasks based on the same RS.

[0364] In some embodiments, UE capability 1 can be defined as a combination of tasks measured by the UE based on the same resources of a cell on a CC, referred to as multitasking, for example, see Figure 5b.

[0365] In some embodiments, the candidate capabilities of UE capability 1 can be a combination of two or more of the following L1 measurement tasks:

[0366] L1-RSRP measurement;

[0367] RLM;

[0368] Beam Fault Detection (BFD);

[0369] Candidate Beam Detection (CBD);

[0370] L1-SINR.

[0371] Optionally, if the UE reports the multi-tasking capability of {L1-RSRP, BFD}, the UE can perform L1-RSRP measurements and BFD measurements simultaneously based on the same RS.

[0372] In some embodiments, the terminal has UE capability 2, which refers to the UE's ability to support the same L1 measurement task for different cells.

[0373] In some embodiments, the RS can be configured with the same L1 measurement purpose for each cell. Alternatively, it can be assumed that two cells in the same time slot can be configured for the same L1 measurement purpose for two cells and two RSs, for example, as shown in Figure 5c.

[0374] In some embodiments, the RS can be configured in several ways, but is not limited to these:

[0375] Case 1: {RS is used for L1-RSRP in cell 1, and RS is used for L1-RSRP in cell 2};

[0376] Case 2: {RS is used for L1-SINR of cell 1, RS is used for L1-SINR of cell 2};

[0377] Case 3: {RS is used for BFD in cell 1, RS is used for BFD in cell 2};

[0378] Case 4: {RS is used in the CBD of Community 1, and RS is used in the CBD of Community 2}.

[0379] In some embodiments, if the purposes configured for two cells are the same, a scaling factor can be designed for the measurement period. This means the UE needs to measure the two cells sequentially. Therefore, the UE needs to spend a significant amount of time performing the measurements. To reduce measurement time, we introduce UE capability 2, such as multiple AOAs.

[0380] In some embodiments, UE capability 2 can be defined as the ability of the UE to support the simultaneous execution of the same L1 measurement task for multiple overlapping reference signals from different directions within the same time slot of the same layer in FR2.

[0381] In some embodiments, UE capability 2 can be defined as:

[0382] Option 1: The number of Transmission Configuration Indication (TCI) states that can be measured simultaneously in the same time slot;

[0383] Option 2: The number of Angle of Arrival (AOA) measurements that can be taken simultaneously in the same time slot;

[0384] Option 3: The number of cells that can be measured simultaneously in the same time slot.

[0385] In some embodiments, the UE can report different quantities depending on UE capability 2. This capability 2 assumes that the UE is equipped with multiple panels and that the UE can simultaneously receive signals from different directions.

[0386] Optionally, if the UE reports that it supports two TCI states to be measured simultaneously, the UE can measure two TCI states simultaneously from two AOA directions of two cells.

[0387] In some embodiments, the terminal has UE capability 3, which means that the UE has the ability to support different L1 measurement tasks for different cells on a CC.

[0388] In some embodiments, UE capability 3 is defined as the ability of the UE to support simultaneous L1 measurements of multiple overlapping reference signals from different directions in the same time slot of a layer in FR2.

[0389] In some embodiments, the terminal has UE capability 4, which means that the UE has the ability to support different or the same L1 measurement tasks for different cells on different CCs.

[0390] UE capability 4 is defined as the UE's ability to simultaneously measure multiple overlapping reference signals from different directions in the same time slot on different CCs in FR2. This capability is called multi-carrier, as shown in Figure 5d for example.

[0391] In some embodiments, UE capability 4 can be defined as:

[0392] Option 1: M CCs can be measured simultaneously in the same time slot. Where M is an integer greater than or equal to 2.

[0393] Option 11: The same or different L1 measurement tasks can be measured simultaneously in the same time slot of M CCs.

[0394] Option 12: Different L1 measurement tasks can be measured simultaneously in the same time slot of M CCs with different combinations.

[0395] Example 1:

[0396] Different L1 measurement tasks between different cells are processed sequentially, as shown in Figure 5e.

[0397] In some embodiments, if the UE supports the multi-tasking capability of {L1-RSRP, BFD}, assuming the UE can sequentially measure the L1-RSRP of two cells, the UE can also sequentially execute the L1-RSRP of one cell and execute the BFD of the other cell.

[0398] In some embodiments, measurement restrictions between two cells are relaxed (or described as loosened):

[0399] If the UE supports multitasking capability, for FR2, when the SSB used for L1-RSRP measurement on one CC is in the same OFDM symbol as the SSB used for BFD measurement from another cell, and the CBD measurement is in the same CC, there is no measurement restriction.

[0400] Measurement time for different tasks:

[0401] If the UE can continuously measure the L1-RSRP of N cells, when the SSBs of two cells overlap, the measurement time of the L1-RSRP of one cell will be N*T. RS Therefore, the UE can also continuously measure the L1-RSRP of cell 1 and the BFD of cell 2. The measurement time is N*T. RS Among them, T RS It is the RS cycle, which can be shared with other L3 measurements. Here, it is just an example to indicate the available measurement cycles for L1 measurements in a cell.

[0402] Example 2:

[0403] Parallel processing of the same L1 measurement tasks across different cells.

[0404] In 5G, L1 measurements will be scaled across different cells or m TRPs. If the UE supports multiple AOA capabilities, the measurement cycle can be shortened. The UE can perform L1-RSRP, BFD, or CBD simultaneously on multiple cells. No scaling factor is required.

[0405] Shorten measurement time.

[0406] Assume the UE needs to perform L1-RSRP on N cells. The measurement period for each cell is TRS. If measurements are performed sequentially, the total measurement time is N*T. RS Where N is the cell number. If the UE can support simultaneous measurements of multiple cells from multiple angles, the measurement latency will be reduced to T. RS Among them, T RS It is the RS cycle, which can be shared with other L3 measurements. This is just an example to indicate the available measurement cycles for L1 measurements in a cell.

[0407] Measurement restrictions between the two communities have been relaxed.

[0408] If the UE supports multiple AOA capabilities, for FR2, when the SSB used for L1-RSRP measurement on one CC and the SSB used for BFD measurement on another cell are located in the same OFDM symbol, and the CBD measurement is located in the same CC, there is no measurement restriction.

[0409] Example 3:

[0410] Parallel processing of different L1 measurement tasks between different cells, for example, as shown in Figure 5f.

[0411] In some embodiments, when the UE supports capability 1 and capability 2, or supports capability 3, the UE can perform simultaneous measurements on different L1 tasks in different cells.

[0412] Traditional 5G measurement limitations between different cells can also be eliminated.

[0413] Assume the UE supports multitasking capabilities of {L1-RSRP, BFD, CBD} and also supports multiple AOAs.

[0414] Measurement restrictions between the two cells have been relaxed:

[0415] If the UE supports multitasking capability and / or multiAOA capability, for FR2, when the SSB used for L1-RSRP measurement on one CC is in the same OFDM symbol as the SSB used for BFD on another cell, and the CBD measurement is in the same CC, there is no measurement restriction.

[0416] Measurement time for different tasks:

[0417] If the UE supports multiple AOAs and / or multi-tasking capabilities, the UE can measure the L1-RSRP of N cells in parallel. When the SSBs of two cells overlap, the measurement time of the L1-RSRP of one cell will be T. RS Optionally, the UE can also measure the L1-RSRP of cell 1 and the BFD of cell 2 in parallel, with a measurement time of T. RS .

[0418] Example 4:

[0419] Measurement limitations for CA have been relaxed:

[0420] If the UE supports multi-carrier capability, for FR2, when the SSB measured by L1-RSRP on one CC is in the same OFDM symbol as the SSB used for BFD measurement from another cell, there are no measurement restrictions for CBD measurements in different CCs.
