Among them, low-frequency bands include Sub-7GHz bands (such as 2.4GHz, 5GHz, 6GHz, etc., which belong to the range of 1-7.25GHz).

[0052] The technical solutions described in some embodiments of this application can be applied to various communication systems, such as: 6th-Generation (6G) systems, subsequent evolution systems of 6G, NR systems, evolution systems of NR systems, 5th-Generation (5G) systems, Beyond 5th-Generation (B5G) systems, Long Term Evolution (LTE) systems, Advanced Long Term Evolution (LTE-A) systems, LTE-based access to unlicensed spectrum (LTE-U) systems, NR-based access to unlicensed spectrum (NR-U) systems, cellular IoT systems, Wireless Local Area Networks (WLAN) systems, Wireless Fidelity (Wi-Fi) systems, Global System for Mobile Communication (GSM) systems, Code Division Multiple Access (CDMA) systems, and Wideband Code Division Multiple Access (CDMA) systems.

For example, V2X can include Vehicle-to-Vehicle (V2V) communication, Vehicle-to-Infrastructure (V2I) communication, Vehicle-to-Pedestrian (V2P) communication, or Vehicle-to-Network (V2N) communication, etc.

[0054] The wireless communication system provided in this embodiment can be applied to at least one of the following communication scenarios, but is not limited to: uplink transmission scenario, downlink transmission scenario, and sidelink transmission scenario. Uplink transmission scenario refers to a scenario where a terminal device sends signals / data to a network device. Downlink transmission scenario refers to a scenario where a network device sends signals / data to a terminal device. Sidelink transmission scenario refers to a scenario where a terminal device sends signals / data to other terminal devices.

[0055] For wireless communication systems, accurate measurement of cell quality and beam quality is fundamental to the effective execution of Radio Resource Management (RRM) and mobility management. Measurements related to RRM requirements and mobility management ensure the performance of wireless communication systems, particularly enhancing system performance in high carrier frequency scenarios (such as the millimeter-wave high-frequency band FR2).

[0056] UE mobility management in the NR system includes: Radio Resource Control (RRC) idle state (RRC_IDLE) or RRC inactive state (RRC_INACTIVE) mobility management, and RRC connected state (RRC_CONNECTED) mobility management.

[0057] Mobility management in RRC connected state is controlled by the network side, including the handover process. An RRC connection exists between the UE and the access network device, and both the UE and the access network device have access stratum (AS) contexts. Unicast data can be transmitted between the UE and the access network device. The network side knows the UE's location at the cell level.

[0058] Mobility management in the RRC inactive state refers to UE-based cell selection and cell reselection. A connection exists between the core network and access network equipment, but the connection between the access network equipment and the UE is suspended (suspend). The UE's AS context resides on a specific access network equipment. Paging is triggered by the Radio Access Network (RAN), and the RAN-based paging area is managed by the RAN. The network side knows the UE's location at the RAN paging area level.

[0059] Mobility management in RRC idle state refers to UE-based cell selection and cell reselection. Paging is initiated by the core network (CN), and the paging area is configured by the core network. There is no AS context for the UE on the access network device side, and there is no RRC connection between the UE and the access network device.

[0060] To achieve energy savings on the UE side, Rel-17 defined measurement relaxation criteria for the UE, such as Radio Link Monitor (RLM) / Beam Failure Detection (BFD) relaxation.

[0061] If both the low mobility criterion and the good serving cell criterion for RLM / BFD relaxation are configured, the UE is allowed to perform RLM and / or BFD relaxation according to the requirements specified in Ts 38.133

[0014] when both relaxed measurement criterion for low mobility and relaxed measurement criterion for good serving cell quality are met.

[0062] If only the good serving cell quality criterion is configured for RLM / BFD relaxation, the UE is allowed to perform RLM and / or BFD relaxation according to requirements specified in Ts 38.133

[0014] when the relaxed measurement criterion for good serving cell quality is met.

[0063] Configuration of RLM relaxation measurement:

[0064] 1> If the received otherConfig includes rlm-RelaxationReportingConfig:

[0065] 2> If rlm-RelaxationReportingConfig is set to setup:

[0066] 3> It then considers itself to be configured to report the relaxation state of RLM measurements in accordance with 5.7.4;

[0067] 2> Otherwise:

[0068] 3> It assumes that it is not configured to report the relaxation state of RLM measurements and stops the running T346j timer associated with the cell group.

[0069] 1> If configured to provide the relaxation state of RLM measurements of a cell group and RLM measurements of the cell group are not stopped:

[0070] 2> If the UE has not sent a UEAssistanceInformation message with rlm-MeasRelaxationState since it was configured to provide the relaxation state of RLM measurements for the cell group; or

[0071] 2> If the relaxation state of RLM measurements for the cell group is currently different from the relaxation state reported in the last transmission of the UEAssistanceInformation message, and timer T346j associated with the cell group is not running, including rlm-MeasRelaxationState and timer T346j associated with the cell group:

[0072] 3> Start timer T346j and set its timer value to rlm-RelaxtionReportingProhibitTimer;

[0073] 3> Initiate transmission of the UEAssistanceInformation message in accordance with 5.7.4.3 to provide the relaxation state of RLM measurements of the cell group.

[0074] 1> If the transmission of the UEAssistanceInformation message is initiated to indicate whether the RRM relaxation criterion for connected mode is met or not:

[0075] 2> If the RRM measurement relaxation criterion for connected mode is satisfied:

[0076] 3> Set the rrm-MeasRelaxationFulfilment to true;

[0077] 2> Otherwise:

[0078] 3> Set the rrm-MeasRelaxationFulfilment to false.

[0079] During Rel-18, a relaxed measurement of Beam Sweeping Factor (BSF) reduction was defined for the UE. BSF is used to calculate the measurement time scaling factor caused by beam sweeping during L1 or L3 measurements in FR2, typically based on an 8-beam direction assumption, i.e., factor = 8. BSF Reduction allows for a reduction in the factor, such as to 2, 4, or 6, to account for the accelerated beam sweeping capabilities or opportunities offered by supporting more antenna panels (multi-panels) in the UE. The UE must be able to report whether it supports BSF Reduction.

[0080] To improve data rate and throughput, Multi-Rx Chain (Multi-Rx) operation was defined for UEs during Rel-16 and Rel-17. This involves simultaneously receiving different downlink signals from different TRPs or cells in different directions via a Multi-Rx chain; that is, using independent beams in different directions on different antenna panels / chains to simultaneously receive different downlink signals. However, there is currently no feasible solution for how the UE enters and exits Multi-Rx operation mode, or even whether it can re-enter Multi-Rx operation mode after exiting.

[0081] Figure 2 shows a flowchart of a communication method provided in an exemplary embodiment of this application. The method is executed by a UE and includes at least some of the following steps:

[0082] Step 220: The UE activates Multi-Rx operation according to the first configuration or the first condition.

[0083] A UE that has activated Multi-Rx operation can simultaneously receive different downlink signals from different TRPs or different cells in different directions via a Multi-Rx chain. In other words, it can simultaneously receive different downlink signals using independent beams in different directions on different antenna panels / chains. In this embodiment, activating Multi-Rx operation can also be understood as enabling Multi-Rx operation or entering a Multi-Rx operation state.

[0084] Step 240: With Multi-Rx operation active, the UE performs the first measurement.

[0085] In some embodiments, the beam sweeping factor (BSF) corresponding to the first measurement is less than the beam sweeping factor corresponding to the second measurement, and / or the measurement period (or measurement interval) corresponding to the first measurement is greater than the measurement duration corresponding to the second measurement.

[0086] In summary, the method provided in this application supports the UE in activating Multi-Rx operation according to a first configuration or a first condition, providing a feasible solution for enabling Multi-Rx operation. During the activation of Multi-Rx operation, the UE can perform a first measurement with a small BSF and / or a long measurement duration. Therefore, the UE can speed up the measurement process, save the measurement time and energy required, and conserve power.

[0087] Figure 3 illustrates a flowchart of a communication method provided in an exemplary embodiment of this application. The method is executed by a UE and includes at least some of the following steps:

[0088] Step 320: The UE activates the Multi-Rx operation according to the second configuration or the second condition.

[0089] A UE that has deactivated Multi-Rx operation cannot simultaneously receive different downlink signals from different TRPs or different cells in different directions via the Multi-Rx chain. In other words, it cannot simultaneously receive different downlink signals using independent beams in different directions on different antenna panels / chains. In this embodiment, deactivating Multi-Rx operation can also be understood as disabling Multi-Rx operation or exiting the Multi-Rx operation state.

[0090] Step 340: During the deactivation of the Multi-Rx operation, the UE performs a second measurement or does not perform a measurement.

[0091] The beam scanning factor corresponding to the second measurement is greater than or equal to the beam scanning factor corresponding to the first measurement, and / or the measurement duration corresponding to the second measurement is less than or equal to the measurement duration corresponding to the first measurement.

[0092] The UE not performing the measurement can also be understood as the UE stopping the measurement.

[0093] In summary, the method provided in this application supports the UE in deactivating Multi-Rx operation based on a second configuration or a second condition, providing a feasible solution for exiting the Multi-Rx operation state. During the deactivation of Multi-Rx operation, the UE can perform a second measurement with a larger BSF and / or a shorter measurement duration to help achieve more accurate RRM and mobility management, or the UE can stop the measurement to further save power consumption.

[0094] Figure 4 shows a flowchart of a communication method provided in an exemplary embodiment of this application. The method is executed by a UE and includes at least some of the following steps:

[0095] Step 420: During the deactivation of Multi-Rx operation, the UE re-evaluates the Multi-Rx operation criteria.

[0096] A UE that has deactivated Multi-Rx operation cannot simultaneously receive different downlink signals from different TRPs or different cells in different directions via the Multi-Rx chain. In other words, it cannot simultaneously receive different downlink signals using independent beams in different directions on different antenna panels / chains. In this embodiment, deactivating Multi-Rx operation can also be understood as disabling Multi-Rx operation or exiting the Multi-Rx operation state.

[0097] The UE re-evaluates the Multi-Rx operating criteria, that is, the UE re-determines whether the Multi-Rx operating criteria are met.

[0098] In summary, the method provided in this application embodiment supports the UE in deactivating Multi-Rx operation, re-evaluating Multi-Rx operation criteria, and providing a feasible solution for restoring the Multi-Rx operation state.

[0099] Figure 5 shows a flowchart of a communication method provided in an exemplary embodiment of this application. The method is executed by a UE and includes at least some of the following steps:

[0100] Step 520: Based on the evaluation results of the Multi-Rx operation criteria, determine whether to reactivate the Multi-Rx operation.

[0101] If the evaluation results meet the Multi-Rx operation criteria, the UE reactivates Multi-Rx operation. Reactivating Multi-Rx operation means that the UE re-enables Multi-Rx operation, or restores the active state of Multi-Rx operation, or re-enters the Multi-Rx operation state. After reactivating Multi-Rx operation, the UE can simultaneously receive different downlink signals from different TRPs or different cells in different directions via the Multi-Rx chain. In other words, it can simultaneously receive different downlink signals using independent beams in different directions on different antenna panels / chains.

[0102] In some embodiments, when Multi-Rx operation is active, the UE performs a first measurement. The BSF corresponding to the first measurement is less than the beam scan factor corresponding to the second measurement, and / or the measurement duration corresponding to the first measurement is greater than the measurement duration corresponding to the second measurement.

[0103] In summary, the method provided in this application supports the UE in reactivating Multi-Rx operation when the evaluation result meets the Multi-Rx operation criteria, providing a feasible solution for re-entering the Multi-Rx operation state. Regardless of whether the UE previously activated or deactivated Multi-Rx operation, it supports the UE in re-evaluating the Multi-Rx operation criteria to re-enter the Multi-Rx operation state. After reactivating Multi-Rx operation, the UE can perform a first measurement with a lower BSF and / or a longer measurement duration. Therefore, the UE can accelerate the measurement speed, save the measurement time and energy required, and conserve power.

[0104] Figure 6 illustrates a flowchart of a communication method provided in an exemplary embodiment of this application. The method is executed by a UE and includes at least some of the following steps:

[0105] Step 620: The UE activates Multi-Rx operation according to the first configuration or the first condition.

[0106] The first configuration is used to configure the UE to activate Multi-Rx operation (also known as instructing the UE to activate Multi-Rx operation), and / or to configure the UE to perform a first measurement (also known as instructing the UE to perform a first measurement).

[0107] In some embodiments, if the UE receives a first configuration for configuring the UE to activate Multi-Rx operation, then the Multi-Rx operation is activated. Alternatively, if the UE receives a first configuration for configuring the UE to perform a first measurement, then the Multi-Rx operation is activated. Or, if the UE receives a first configuration for configuring both the Multi-Rx operation and the first measurement, then the Multi-Rx operation is activated. After activating the Multi-Rx operation, the UE performs the first measurement.

[0108] In some embodiments, the first configuration is carried in RRC signaling, or the first configuration is carried in pre-configuration signaling.

[0109] The first condition includes one or more of the following: the UE supports Multi-Rx operation capability; the UE supports the radio frequency capability of multiple antennas or multiple antenna panels; the UE supports the measurement capability of multiple antennas or multiple antenna panels; the UE meets the Multi-Rx operation criteria; the UE is configured for group-based beam reporting; the first timer times out; the first timer times out and a first duration has elapsed; the third timer times out; the third timer times out and a first duration has elapsed. It should be emphasized that the first condition can include any one or more of the above. For example, the first condition includes: the UE supports Multi-Rx operation capability and the UE meets the Multi-Rx operation criteria. For example, the first condition includes: the UE supports Multi-Rx operation capability, the UE meets the Multi-Rx operation criteria, and the UE is configured for group-based beam reporting. For example, the first condition includes: the UE supports Multi-Rx operation capability, the UE meets the Multi-Rx operation criteria, and the UE is configured for group-based beam reporting. For example, the first condition includes: the UE supports the radio frequency capability of multiple antennas or multiple antenna panels, the UE supports the measurement capability of multiple antennas or multiple antenna panels, the UE meets the Multi-Rx operation criteria, and the UE is configured for group-based beam reporting. For example, the first condition includes: the UE supports the RF capability of multiple antennas or multiple antenna panels, the UE supports the measurement capability of multiple antennas or multiple antenna panels, and the third timer times out. For example, the first condition includes: the UE supports the RF capability of multiple antennas or multiple antenna panels, the UE supports the measurement capability of multiple antennas or multiple antenna panels, and the third timer times out and a first duration has elapsed. For example, the first condition includes: the UE supports the RF capability of multiple antennas or multiple antenna panels, the UE supports the measurement capability of multiple antennas or multiple antenna panels, and the first timer times out and a first duration has elapsed. For example, the first condition includes: the UE supports Multi-Rx operation capability, and the first timer times out and a first duration has elapsed. For example, the first condition includes: the UE is configured for group-based beam reporting, and the first timer times out and a first duration has elapsed. For example, the first condition includes: the UE is configured for group-based beam reporting, and the third timer times out and a first duration has elapsed.

[0110] The first timer is related to the duration of the Single-Rx operation and / or the duration of the second measurement. For example, the duration of the first timer represents the maximum duration of the Single-Rx operation and / or the maximum duration of the second measurement. During the timing of the first timer, the Single-Rx operation and / or the second measurement are in an active state (i.e., enabled state); after the first timer expires, the Single-Rx operation and / or the second measurement are in a deactivated state (i.e., disabled state). This application does not limit the name of the first timer; for example, the first timer may also be called a Single-Rx timer, a normal measurement timer, or a conventional measurement timer.

[0111] In some embodiments, the first timer is configured by the network device, agreed upon by the communication protocol, or determined autonomously by the UE.

[0112] The Rx operation activated during the third timer's timing period is different from the Rx operation activated before the third timer's start. That is, the Rx operation activated by the UE before the third timer starts is different from the Rx operation activated by the UE after the third timer starts, and / or, the measurement performed by the UE before the third timer starts is different from the measurement performed by the UE after the third timer starts. The duration of the third timer represents the maximum duration of the new Rx operation (i.e., the Rx operation activated during the third timer's start) and / or the maximum duration of the new measurement (i.e., the measurement performed during the third timer's start). For example, before the third timer starts, the UE activates a Multi-Rx operation (and / or performs a first measurement); during the third timer's timing period, the UE activates a Single-Rx operation (and / or performs a second measurement); the duration of the third timer then represents the maximum duration of the Single-Rx operation (i.e., the new Rx operation) and / or the maximum duration of the second measurement (i.e., the new measurement mode). For example, before the third timer starts, the UE activates a Single-Rx operation (and / or performs a second measurement). During the timing of the third timer, the UE activates a Multi-Rx operation (and / or performs a first measurement). The duration of the third timer represents the maximum duration of the Multi-Rx operation (i.e., the new Rx operation) and / or the maximum duration of the first measurement (i.e., the new measurement mode). This application does not limit the name of the third timer; for example, the third timer may also be called a new operation timer, a new measurement timer, or a new tendency timer.

[0113] In some embodiments, the third timer is configured by the network device, agreed upon by the communication protocol, or determined autonomously by the UE.

[0114] In some embodiments, the duration of the first timer and the duration of the third timer may be the same or different.

[0115] In some embodiments, the first duration is represented by time or time units. For example, the first duration is t1 seconds (s), or t1 milliseconds (ms), or t1 microseconds (μs), or t1 time units, where t1 > 0. In this application, the time unit includes one or more of the following: symbols, symbol groups, subframes, frames, time slots, and sub-time slots. For example, the first duration is t1 symbols, or t1 symbol groups, or t1 subframes, or t1 frames, or t1 time slots, or t1 sub-time slots. The first duration is configured by the network device, agreed upon by the communication protocol, or determined autonomously by the UE. This application does not limit the name of the first duration; for example, the first duration may also be called a first offset, or an activation duration, or an activation offset.

[0116] Multi-Rx operating criteria include one or more of the following: the UE is located at the edge of the serving cell, and the serving cell's signal quality is below a first threshold. Signal quality is expressed using Reference Signal Received Power (RSRP), Reference Signal Receiving Quality (RSRQ), or Signal to Interference plus Noise Ratio (SINR). Multi-Rx operating criteria are configured by network equipment, agreed upon by the communication protocol, or determined autonomously by the UE.

[0117] In some embodiments, the first condition is pre-configured, either by the network device, by the communication protocol, or by the UE itself. Pre-configuration can be achieved by pre-storing corresponding codes, tables, or other means of indicating relevant information in the UE, or by pre-configuration signaling.

[0118] In some embodiments, the UE activates Multi-Rx operation when a first condition is met.

[0119] In some embodiments, the UE performs the first measurement while Multi-Rx operation is active. This can also be understood as the UE performing the first measurement during the activation of Multi-Rx operation.

[0120] In some embodiments, the first measurement includes neighbor cell measurements at layer 1 and / or neighbor cell measurements at layer 3. The BSF corresponding to the first measurement is less than the BSF corresponding to the second measurement, and / or the measurement duration corresponding to the first measurement is greater than the measurement duration corresponding to the second measurement. For example, the first measurement may be a relaxed measurement of BSF reduction, or a relaxed measurement of measurement interval increase, or a relaxed measurement of Radio Link Monitor (RLM) / Beam Failure Detection (BFD).

[0121] In some embodiments, the UE also starts a second timer and / or a third timer. For example, the UE activates Multi-Rx operation and starts the second timer, or the UE activates Multi-Rx operation and starts the third timer, or the UE activates Multi-Rx operation and starts both the second and third timers.

[0122] The second timer is related to the duration of the Multi-Rx operation and / or the duration of the first measurement. For example, the duration of the second timer represents the maximum duration of the Multi-Rx operation and / or the maximum duration of the first measurement. During the timing of the second timer, the Multi-Rx operation and / or the first measurement are in an active state (i.e., enabled state); after the second timer expires, the Multi-Rx operation and / or the first measurement are in a deactivated state (i.e., disabled state). This application does not limit the name of the second timer; for example, the second timer may also be called a Multi-Rx timer, a relaxation measurement timer, or a BSF Reduction measurement timer.

[0123] In some embodiments, the second timer is configured by the network device, agreed upon by the communication protocol, or determined autonomously by the UE.

[0124] Step 640: The UE activates the Multi-Rx operation according to the second configuration or the second condition.

[0125] In some embodiments, the second configuration is used to configure the UE to deactivate Multi-Rx operation (also referred to as instructing the UE to deactivate Multi-Rx operation), and / or to configure the UE to perform a second measurement (also referred to as instructing the UE to perform a second measurement).

[0126] In some embodiments, the second configuration is used to configure the UE to activate Single-Rx operation (also referred to as instructing the UE to activate Single-Rx operation), and / or to configure the UE to perform a second measurement (also referred to as instructing the UE to perform a second measurement).

[0127] In some embodiments, if the UE receives a second configuration for configuring the UE to deactivate Multi-Rx operation, then the Multi-Rx operation is deactivated. Alternatively, if the UE receives a second configuration for configuring the UE to perform a second measurement, then the Multi-Rx operation is deactivated. Alternatively, if the UE receives a second configuration for configuring the UE to both deactivate Multi-Rx operation and perform a second measurement, then the Multi-Rx operation is deactivated. Alternatively, if the UE receives a second configuration for configuring the UE to activate Single-Rx operation, then both Multi-Rx operation and Single-Rx operation are deactivated. Alternatively, if the UE receives a second configuration for configuring both Single-Rx operation and perform a second measurement, then both Multi-Rx operation and Single-Rx operation are deactivated. After deactivating Multi-Rx operation, the UE performs the second measurement or stops the measurement.

[0128] The second condition includes one or more of the following: the UE's current preference is Single-Rx operation; the UE is in an overheating state; the UE is in a power-saving state; the UE detects a Radio Link Failure (RLF); the UE completes a valid report / indication related to Multi-Rx operation; the second timer times out; the second timer times out and a second duration has elapsed; the third timer times out; the third timer times out and a second duration has elapsed; the third duration ends; the UE does not meet the Multi-Rx operation criteria. It should be emphasized that the second condition can include any one or more of the above.

[0129] The UE's current preference is Single-Rx operation, which can also be understood as the UE expecting to perform Single-Rx operation or the UE recommending to perform Single-Rx operation.

[0130] The details regarding the second and third timers have been described previously and will not be repeated here.

[0131] In some embodiments, the duration of the second timer and the duration of the third timer may be the same or different.

[0132] In some embodiments, the second duration is represented by time or time units. For example, the second duration is t2 seconds (s), or t2 milliseconds (ms), or t2 microseconds (μs), or t2 time units, where t2 > 0. Exemplarily, the second duration is t2 symbols, or t2 symbol groups, or t2 subframes, or t2 frames, or t2 time slots, or t2 sub-time slots. The second duration is configured by the network device, agreed upon by the communication protocol, or determined autonomously by the UE. This application does not limit the name of the second duration; exemplaryly, the second duration may also be called a second offset, or deactivation duration, or deactivation offset.

[0133] The third duration is related to the total time it takes for the UE to complete one measurement and one report while Multi-Rx operation is active. For example, the third duration represents the total time it takes for the UE to complete one measurement and one report during the active period of Multi-Rx operation. The third duration is expressed in time or time units. For example, the third duration is t3 seconds (s), or t3 milliseconds (ms), or t3 microseconds (μs), or t3 time units, where t3 > 0. For example, the third duration is t3 symbols, or t3 symbol groups, or t3 subframes, or t3 frames, or t3 time slots, or t3 sub-time slots. The third duration is configured by the network device, agreed upon by the communication protocol, or determined autonomously by the UE. This application does not limit the name of the third duration; for example, the third duration can also be called the total measurement duration or the total reporting duration.

[0134] In some embodiments, the second condition is pre-configured, either by the network device, by the communication protocol, or by the UE itself. Pre-configuration can be achieved by pre-storing corresponding codes, tables, or other means of indicating relevant information in the UE, or by pre-configuration signaling.

[0135] In some embodiments, if the second condition is met, the UE deactivates Multi-Rx operation and / or activates Single-Rx.

[0136] In some embodiments, the UE performs the second measurement or does not perform the measurement when the Multi-Rx operation is in a deactivated state and / or the Single-Rx operation is in a activated state. This can also be understood as the UE performing the second measurement or not performing the measurement during the activation of the Single-Rx operation and / or the deactivated state of the Multi-Rx operation.

[0137] In some embodiments, the second measurement includes neighbor cell measurements of layer 1 and / or neighbor cell measurements of layer 3. The BSF corresponding to the first measurement is less than the BSF corresponding to the second measurement, and / or the measurement duration corresponding to the first measurement is greater than the measurement duration corresponding to the second measurement. Exemplarily, the second measurement is a non-relaxation measurement, which may also be referred to as a normal measurement or a conventional measurement.

[0138] In some embodiments, the UE reports UE Assistance Information (UAI). For example, the UE deactivates Multi-Rx operation and reports UAI, or the UE activates Single-Rx operation and reports UAI, or the UE reports UAI according to a second configuration, or the UE reports UAI according to a second condition, or the UE reports UAI according to a first configuration, or the UE reports UAI according to a first condition.

[0139] In some embodiments, the UAI can provide a UE's preference indication for Multi-Rx operations on FR2. If the network device is configured for the UE to report UAI, the UE can report UAI when it detects a preference for Multi-Rx operations on FR2 and that the preference changes. Here, a change in preference can be understood as a change in the expected operation or a change in the recommended operation.

[0140] In some embodiments, the UAI carries one or more of the following information: information indicating deactivation of Multi-Rx operation; information indicating a tendency for Single-Rx operation; information indicating overheating; information indicating power saving; information indicating RLF; information indicating failure to meet Multi-Rx operation criteria.

[0141] In some embodiments, the UE also starts a first timer and / or a third timer. For example, the UE deactivates Multi-Rx operation and starts the first timer, or the UE deactivates Multi-Rx operation and starts the third timer, or the UE deactivates Multi-Rx operation and starts both the first and third timers, or the UE activates Single-Rx operation and starts the first timer, or the UE activates Single-Rx operation and starts the third timer, or the UE activates Single-Rx operation and starts both the first and third timers.

[0142] Step 660: The UE reassesses whether it meets the Multi-Rx operating criteria.

[0143] In some embodiments, the UE autonomously reassesses whether it meets the Multi-Rx operation criteria; or, the UE reassesses whether it meets the Multi-Rx operation criteria based on triggering signaling from the network device; or, the UE reassesses whether it meets the Multi-Rx operation criteria if a third condition is met.

[0144] The triggering signaling includes one or more of the following: configuration signaling for Multi-Rx operation; configuration signaling for the first measurement; configuration signaling for group-based beam reporting; and signaling indicating UAI reporting.

[0145] The third condition includes one or more of the following: the first timer times out; the first timer times out and a fourth duration has elapsed; the second timer times out; the second timer times out and a fourth duration has elapsed; the third timer times out; the third timer times out and a fourth duration has elapsed; and the fifth duration ends. It should be emphasized that the third condition can include any one or more of the above.

[0146] In some embodiments, the fourth duration is represented by time or time units. For example, the fourth duration is t4 seconds (s), or t4 milliseconds (ms), or t4 microseconds (μs), or t4 time units, where t4 > 0. Exemplarily, the fourth duration is t4 symbols, or t4 symbol groups, or t4 subframes, or t4 frames, or t4 time slots, or t4 sub-time slots. Optionally, the fourth duration may also be referred to as the fourth offset. The fourth duration is configured by the network device, agreed upon by the communication protocol, or determined autonomously by the UE. This application does not limit the name of the fourth duration; exemplaryly, the fourth duration may also be referred to as the fourth offset, or reactivation duration, or reactivation offset.

[0147] The fifth duration is related to the total time it takes for the UE to complete one evaluation of the Multi-Rx operating criteria. For example, the fifth duration represents the total time it takes for the UE to complete one measurement and one evaluation of the Multi-Rx operating criteria. The fifth duration is expressed in time or time units. For example, the fifth duration is t5 seconds (s), or t5 milliseconds (ms), or t5 microseconds (μs), or t5 time units, where t5 > 0. For example, the fifth duration is t5 symbols, or t5 symbol groups, or t5 subframes, or t5 frames, or t5 time slots, or t5 sub-time slots. The fifth duration is configured by the network device, agreed upon by the communication protocol, or determined autonomously by the UE. This application does not limit the name of the fifth duration; for example, the fifth duration can also be called the total evaluation duration.

[0148] In some embodiments, the third condition is pre-configured, configured by the network device, agreed upon by the communication protocol, or determined autonomously by the UE. Pre-configuration can be achieved by pre-storing corresponding codes, tables, or other means of indicating relevant information in the UE, or by pre-configuration signaling.

[0149] In some embodiments, Multi-Rx operation is reactivated if the evaluation result meets the Multi-Rx operation criteria. For example, if the UE is located at the edge of the serving cell and / or the signal quality of the UE's serving cell is below a first threshold, the Multi-Rx operation criteria are met, and the UE reactivates Multi-Rx operation.

[0150] In summary, the method provided in this application provides a specific and feasible solution for the activation, deactivation, and reactivation of Multi-Rx operation, supports the UE to flexibly enter or exit the Multi-Rx operation state, realizes flexible switching between the first measurement and the second measurement, and achieves a balance between RRM management and mobility management.

[0151] In some embodiments, step 620 is performed separately to implement the activation method of the Multi-Rx operation. Step 640 is performed separately to implement the deactivation method of the Multi-Rx operation. Step 660 is performed separately to implement the reactivation method of the Multi-Rx operation.

[0152] In some embodiments, steps 620 and 640 are performed in combination to implement the activation and deactivation method for Multi-Rx operations.

[0153] In some embodiments, steps 640 and 660 are performed in combination to implement a deactivation and reactivation method for Multi-Rx operations.

[0154] In some embodiments, steps 620, 640, and 660 are performed in combination to implement a method for activating, deactivating, and reactivating Multi-Rx operations.

[0155] Figure 7 illustrates a flowchart of a communication method provided in an exemplary embodiment of this application. The method is executed by a network device and includes at least some of the following steps:

[0156] Step 720: Send the first configuration or first condition, which is used to activate the Multi-Rx operation.

[0157] In this embodiment of the application, activating the Multi-Rx operation can also be understood as enabling the Multi-Rx operation or entering the Multi-Rx operation state.

[0158] The first configuration is used to configure the UE to activate Multi-Rx operation (also known as instructing the UE to activate Multi-Rx operation), and / or to configure the UE to perform a first measurement (also known as instructing the UE to perform a first measurement).

[0159] The first condition includes one or more of the following: the UE supports Multi-Rx operation capability; the UE supports the RF capability of multiple antennas or multiple antenna panels; the UE supports the measurement capability of multiple antennas or multiple antenna panels; the UE meets the Multi-Rx operation criteria; the UE is configured for group-based beam reporting; the first timer times out; the first timer times out and a first duration has elapsed; the third timer times out; the third timer times out and a first duration has elapsed. It should be emphasized that the first condition may include any one or more of the above.

[0160] In some embodiments, the network device further receives a first measurement result. The first measurement result is acquired by the UE during the activation of Multi-Rx operation by performing a first measurement. The BSF corresponding to the first measurement is less than the BSF corresponding to the second measurement, and / or, the measurement duration corresponding to the first measurement is greater than the measurement duration corresponding to the second measurement.

[0161] The relevant details regarding the first configuration, first conditions, and first measurement can be found in step 620, and will not be repeated here.

[0162] In summary, the method provided in this application embodiment supports network devices sending a first configuration or a first condition to activate Multi-Rx operation, providing a feasible solution for enabling Multi-Rx operation.

[0163] Figure 8 shows a flowchart of a communication method provided in an exemplary embodiment of this application. The method is performed by a network device and includes at least some of the following steps:

[0164] Step 820: Send the second configuration or second condition, which is used to deactivate the Multi-Rx operation.

[0165] In this embodiment of the application, deactivating the Multi-Rx operation can also be understood as: disabling the Multi-Rx operation, or exiting the Multi-Rx operation state.

[0166] In some embodiments, the second configuration is used to configure the UE to deactivate Multi-Rx operation (also referred to as instructing the UE to deactivate Multi-Rx operation), and / or to configure the UE to perform a second measurement (also referred to as instructing the UE to perform a second measurement).

[0167] In some embodiments, the second configuration is used to configure the UE to activate Single-Rx operation (also referred to as instructing the UE to activate Single-Rx operation), and / or to configure the UE to perform a second measurement (also referred to as instructing the UE to perform a second measurement).

[0168] The second condition includes one or more of the following: the UE's current preference is Single-Rx operation; the UE is in an overheating state; the UE is in a power-saving state; the UE detects a Radio Link Failure (RLF); the UE completes a valid report / indication related to Multi-Rx operation; the second timer times out; the second timer times out and a second duration has elapsed; the third timer times out; the third timer times out and a second duration has elapsed; the third duration ends; the UE does not meet the Multi-Rx operation criteria. It should be emphasized that the second condition can include any one or more of the above.

[0169] In some embodiments, the network device further receives a second measurement result. The second measurement result is acquired by the UE during the activation of Single-Rx operation by performing a second measurement. The BSF corresponding to the first measurement is less than the BSF corresponding to the second measurement, and / or the measurement duration corresponding to the first measurement is greater than the measurement duration corresponding to the second measurement.

[0170] In some embodiments, the network device does not receive measurement results. The UE does not perform measurements during the deactivation period of Multi-Rx operation.

[0171] The relevant details regarding the second configuration, second conditions, and second measurement can be found in step 640 and will not be repeated here.

[0172] In summary, the method provided in this application embodiment supports network devices sending a second configuration or a second condition to deactivate Multi-Rx operation, providing a feasible solution for disabling Multi-Rx operation.

[0173] Figure 9 illustrates a flowchart of a communication method provided in an exemplary embodiment of this application. The method is executed by a network device and includes at least some of the following steps:

[0174] Step 920: Send a trigger signaling or third condition, which is used to trigger the UE to re-evaluate the Multi-Rx operation criteria.

[0175] The triggering signaling includes one or more of the following: configuration signaling for Multi-Rx operation; configuration signaling for the first measurement; configuration signaling for group-based beam reporting; and signaling indicating UAI reporting.

[0176] The third condition includes one or more of the following: the first timer times out; the first timer times out and a fourth duration has elapsed; the second timer times out; the second timer times out and a fourth duration has elapsed; the third timer times out; the third timer times out and a fourth duration has elapsed; and the fifth duration ends. It should be emphasized that the third condition can include any one or more of the above.

[0177] Multi-Rx operating criteria include one or more of the following: the UE is located at the edge of the serving cell, and the serving cell's signal quality is below a first threshold. Signal quality is represented by RSRP, RSRQ, or SINR. Multi-Rx operating criteria are configured by network equipment, agreed upon by the communication protocol, or determined autonomously by the UE.

[0178] The evaluation results of the Multi-Rx operation criteria are used by the UE to determine whether to reactivate Multi-Rx operation. If the evaluation results indicate that the Multi-Rx operation criteria are met, the UE reactivates Multi-Rx operation.

[0179] In some embodiments, the network device further receives a first measurement result. The first measurement result is acquired by the UE during the activation of Multi-Rx operation by performing a first measurement. The BSF corresponding to the first measurement is less than the BSF corresponding to the second measurement, and / or, the measurement duration corresponding to the first measurement is greater than the measurement duration corresponding to the second measurement.

[0180] For details regarding the triggering signal and the third condition, please refer to step 640; for details regarding the first measurement, please refer to step 620. These details will not be repeated here.

[0181] In summary, the method provided in this application embodiment supports network devices sending triggering signaling or third conditions to trigger the UE to re-evaluate the Multi-Rx operation criteria, so that the UE can reactivate Multi-Rx operation and provides a feasible solution for re-entering the Multi-Rx operation state.

[0182] In some embodiments, step 720 is performed separately to implement the activation method of the Multi-Rx operation. Step 820 is performed separately to implement the deactivation method of the Multi-Rx operation. Step 920 is performed separately to implement the reactivation method of the Multi-Rx operation.

[0183] In some embodiments, steps 720 and 820 are performed in combination to implement the activation and deactivation method for Multi-Rx operations.

[0184] In some embodiments, steps 820 and 920 are performed in combination to implement a deactivation and reactivation method for Multi-Rx operations.

[0185] In some embodiments, steps 720, 820, and 920 are performed in combination to implement a method for activating, deactivating, and reactivating Multi-Rx operations.

[0186] Furthermore, this application also supports flexible combinations based on the embodiments shown in Figures 2 to 9, as shown in Figures 10 to 18.

[0187] Figure 10 illustrates a flowchart of a communication method provided in an exemplary embodiment of this application. The method is performed by a network device and a UE, and includes at least some of the following steps:

[0188] Step 1001: UE reports capability information.

[0189] The capability information reported by the UE includes: whether the UE supports Multi-Rx operation capability and / or whether the UE supports Multi-Rx preference indication capability. If the UE supports Multi-Rx operation capability, it means that the UE supports the radio frequency capability of multi-antenna panels and / or the measurement capability of multi-antenna panels. For example, the UE supports performing Layer 1 neighbor cell measurement and / or Layer 3 neighbor cell measurement using a Multi-Rx chain. If the UE supports Multi-Rx preference indication capability, it means that the UE supports reporting indication information indicating its preference for Multi-Rx operation.

[0190] In some embodiments, a UE in RRC connected state reports this capability information.

[0191] In some embodiments, the UE reports this capability information when establishing an RRC connection.

[0192] Step 1002: Configure network devices to evaluate UE operating guidelines for Multi-Rx.

[0193] In other words, the network device instructs the UE to assess whether the Multi-Rx operating criteria are met. The Multi-Rx operating criteria include one or more of the following: the UE is located at the edge of the serving cell, and the signal quality of the UE's serving cell is below a first threshold. Signal quality is represented by RSRP, RSRQ, or SINR.

[0194] Step 1003: If the Multi-Rx operation criteria are met, the UE activates Multi-Rx operation.

[0195] If the UE is located at the edge of the serving cell and / or the signal quality of the UE's serving cell is lower than the first threshold, the Multi-Rx operation criteria are met, and the UE activates Multi-Rx operation.

[0196] During the activation of Multi-Rx operation, the UE performs a first measurement. The BSF corresponding to the first measurement is less than the BSF corresponding to the second measurement, and / or, the measurement duration corresponding to the first measurement is greater than the measurement duration corresponding to the second measurement. For example, during the activation of Multi-Rx operation, the UE performs a Layer 1 and / or Layer 3 neighbor cell relaxation measurement for BSF reduction. For example, during the activation of Multi-Rx operation, the UE performs a Layer 1 and / or Layer 3 neighbor cell relaxation measurement for RLM / BFD.

[0197] Step 1004: UE reports the first UAI.

[0198] The first UAI carries one or more of the following information: indication of Single-Rx operation tendency; indication of overheating; indication of power saving; and indication of RLF.

[0199] In some embodiments, step 1004 is performed simultaneously with step 1003, or step 1004 is performed after step 1003.

[0200] Step 1005: The UE starts Timer T4 to deactivate Multi-Rx operation and / or activate Single-Rx operation.

[0201] Timer T4 includes a first timer and / or a third timer.

[0202] The duration of the first timer represents the maximum duration of the Single-Rx operation and / or the maximum duration of the second measurement. This application does not limit the name of the first timer; for example, the first timer may also be referred to as a Single-Rx timer, a normal measurement timer, or a conventional measurement timer.

[0203] The duration of the third timer represents the maximum duration of a Single-Rx operation (i.e., a new Rx operation activated during the duration of the third timer) and / or the maximum duration of a second measurement (i.e., a new measurement performed during the duration of the third timer). This application does not limit the name of the third timer; for example, the third timer may also be referred to as a new operation timer, a new measurement timer, or a new tendency timer.

[0204] In some embodiments, step 1005 is performed simultaneously with step 1004, or step 1005 is performed after step 1004.

[0205] In some embodiments, when Timer T4 is started, regardless of whether the UE meets the Multi-Rx operation criteria, the UE begins to fall back to the Single-Rx operation state, that is, the UE activates Single-Rx operation. During the timing of Timer T4, regardless of whether the UE meets the Multi-Rx operation criteria, the UE remains in the Single-Rx operation state, that is, the UE remains in the active state of Single-Rx operation until Timer T4 ends or times out.

[0206] During Single-Rx operation activation, the UE performs a second measurement or does not perform a measurement. For example, during Single-Rx operation activation, the UE performs normal neighbor cell measurements for Layer 1 and / or Layer 3. For example, during Single-Rx operation activation, the UE does not perform neighbor cell measurements for Layer 1 and / or Layer 3.

[0207] Step 1006: Timer T4 times out, UE re-evaluates Multi-Rx operating criteria.

[0208] In some embodiments, as Timer T4 ends timing, the UE re-evaluates whether the Multi-Rx operation criteria are met.

[0209] In some embodiments, after Timer T4 times out and a fourth duration has elapsed, the UE re-evaluates whether the Multi-Rx operation criteria are met. The fourth duration is represented by time or time units. For example, the fourth duration is t4 seconds (s), or t4 milliseconds (ms), or t4 microseconds (μs), or t4 time units, where t4 > 0. Exemplarily, the fourth duration is t4 symbols, or t4 symbol groups, or t4 subframes, or t4 frames, or t4 time slots, or t4 sub-time slots. The fourth duration is configured by the network device, agreed upon by the communication protocol, or determined autonomously by the UE. This application does not limit the name of the fourth duration; exemplaryly, the fourth duration may also be called the fourth offset, or reactivation duration, or reactivation offset.

[0210] Step 1007: The UE determines whether to reactivate Multi-Rx operation based on the evaluation results of the Multi-Rx operation criteria.

[0211] If the evaluation result meets the Multi-Rx operation criteria, the UE reactivates Multi-Rx operation. For example, if the UE is located at the edge of the serving cell and / or the signal quality of the UE's serving cell is below a first threshold, the Multi-Rx operation criteria are met, and the UE reactivates Multi-Rx operation and / or performs the first measurement.

[0212] In some embodiments, if the evaluation result meets the Multi-Rx operation criteria, the UE also updates the UAI report, for example, the UE sends a second UAI. The second UAI carries an indication of the tendency state for Multi-Rx operation, or the second UAI carries indication information for reactivating Multi-Rx operation.

[0213] If the evaluation result indicates that the Multi-Rx operation criteria are not met, the UE reactivates Single-Rx operation. For example, if the UE is not located at the edge of the serving cell and / or the signal quality of the UE's serving cell is higher than a first threshold, the Multi-Rx operation criteria are not met, and the UE reactivates Single-Rx operation and / or performs a second measurement.

[0214] In some embodiments, if the evaluation result indicates that the Multi-Rx operation criteria are not met, the UE may also update the UAI report, for example, by sending a second UAI. The second UAI carries an indication of a preference for Single-Rx operation, or it carries an indication to reactivate Single-Rx operation.

[0215] In summary, the method provided in this application supports the UE entering a Multi-Rx operation state according to the network device configuration. When the UE's tendency changes to Single-Rx operation, or it is in an overheating state, a power-saving state, or an RLF occurs, the UE is forced to exit the Multi-Rx operation state, realizing flexible switching between Multi-Rx and Single-Rx operations. This allows for timely adjustment of the UE's measurement behavior to conform to network-side instructions and the actual communication environment, ensuring overall efficiency within the communication system. Furthermore, it supports the UE reassessing whether the Multi-Rx operation criteria are met when Timer T4 expires, enabling the UE to flexibly and promptly reactivate Multi-Rx operation.

[0216] Figure 11 illustrates a flowchart of a communication method provided in an exemplary embodiment of this application. The method is performed by a network device and a UE, and includes at least some of the following steps:

[0217] Step 1101: The UE reports capability information.

[0218] The capability information reported by the UE includes: whether the UE supports Multi-Rx operation capability and / or whether the UE supports Multi-Rx tendency indication capability.

[0219] If the UE supports Multi-Rx operation capability, it means that the UE supports the radio frequency capability of multiple antenna panels and / or the measurement capability of multiple antenna panels. For example, the UR supports performing layer 1 neighbor cell measurement and / or layer 3 neighbor cell measurement using the Multi-Rx chain.

[0220] If the UE supports the Multi-Rx preference indication capability, it means that the UE supports reporting indication information indicating that it prefers Multi-Rx operation.

[0221] In some embodiments, a UE in RRC connected state reports this capability information.

[0222] In some embodiments, the UE reports this capability information when establishing an RRC connection.

[0223] Step 1102: Configure network devices to evaluate UE operating guidelines for Multi-Rx.

[0224] In other words, the network device instructs the UE to assess whether the Multi-Rx operating criteria are met. The Multi-Rx operating criteria include one or more of the following: the UE is located at the edge of the serving cell, and the signal quality of the UE's serving cell is below a first threshold. Signal quality is represented by RSRP, RSRQ, or SINR.

[0225] Step 1103: If the Multi-Rx operation criteria are met, the UE activates Multi-Rx operation.

[0226] If the UE is located at the edge of the serving cell and / or the signal quality of the UE's serving cell is lower than the first threshold, the Multi-Rx operation criteria are met, and the UE activates Multi-Rx operation.

[0227] During the activation of Multi-Rx operation, the UE performs a first measurement. The BSF corresponding to the first measurement is less than the BSF corresponding to the second measurement, and / or, the measurement duration corresponding to the first measurement is greater than the measurement duration corresponding to the second measurement. For example, during the activation of Multi-Rx operation, the UE performs a Layer 1 and / or Layer 3 neighbor cell relaxation measurement for BSF reduction. For example, during the activation of Multi-Rx operation, the UE performs a Layer 1 and / or Layer 3 neighbor cell relaxation measurement for RLM / BFD.

[0228] Step 1104: If the UE completes a valid report related to a Multi-Rx operation or the third duration ends, the UE deactivates the Multi-Rx operation and / or activates the Single-Rx operation.

[0229] Valid reports related to Multi-Rx operations, such as: valid reports or indications based on Rel-16 / 18 UE capability.

[0230] The third duration represents the total time it takes for the UE to complete one measurement and one report during the activation period of Multi-Rx operation. The third duration is expressed in time or time units. For example, the third duration is t3 seconds (s), or t3 milliseconds (ms), or t3 microseconds (μs), or t3 time units, where t3 > 0. Exemplarily, the third duration is t3 symbols, or t3 symbol groups, or t3 subframes, or t3 frames, or t3 time slots, or t3 sub-time slots. The third duration is configured by the network device, agreed upon by the communication protocol, or determined autonomously by the UE. This application does not limit the name of the third duration; for example, the third duration can also be called the total measurement duration or the total reporting duration.

[0231] During Single-Rx operation activation, the UE performs a second measurement or does not perform a measurement. For example, during Single-Rx operation activation, the UE performs normal neighbor cell measurements for Layer 1 and / or Layer 3. For example, during Single-Rx operation activation, the UE does not perform neighbor cell measurements for Layer 1 and / or Layer 3.

[0232] Step 1105: UE re-evaluates Multi-Rx operating guidelines.

[0233] In some embodiments, the UE autonomously reassesses whether it meets the Multi-Rx operating criteria. For example, when entering an overheating state or a power-saving state, the UE autonomously reassesses whether it meets the Multi-Rx operating criteria. Another example is when an RLF (Recurrent Leakage Fault) occurs, the UE autonomously reassesses whether it meets the Multi-Rx operating criteria.

[0234] In some embodiments, the UE reassesses whether it meets the Multi-Rx operation criteria based on triggering signaling from the network device. For example, the UE reassesses whether it meets the Multi-Rx operation criteria upon receiving configuration signaling for Multi-Rx operation. Alternatively, the UE reassesses whether it meets the Multi-Rx operation criteria upon receiving configuration signaling for a first measurement. Another example is the UE reassessing whether it meets the Multi-Rx operation criteria upon receiving configuration signaling for group-based beam reporting. Yet another example is the UE reassessing whether it meets the Multi-Rx operation criteria upon receiving indication signaling for reporting a UAI.

[0235] In some embodiments, if the third condition is met, the UE re-evaluates whether the Multi-Rx operation criteria are met. For example, if the fifth duration ends, the UE re-evaluates whether the Multi-Rx operation criteria are met. The fifth duration represents the total time for the UE to complete one measurement and one evaluation of the Multi-Rx operation criteria. The fifth duration is expressed in time or time units. For example, the fifth duration is t5 seconds (s), or t5 milliseconds (ms), or t5 microseconds (μs), or t5 time units, where t5 > 0. For example, the fifth duration is t5 symbols, or t5 symbol groups, or t5 subframes, or t5 frames, or t5 time slots, or t5 sub-time slots. The fifth duration is configured by the network device, agreed upon by the communication protocol, or determined autonomously by the UE. This application does not limit the name of the fifth duration; for example, the fifth duration can also be called the total evaluation duration. The relevant content of the third condition is referred to in step 660 and will not be repeated here.

[0236] Step 1106: The UE determines whether to reactivate Multi-Rx operation based on the evaluation results of the Multi-Rx operation criteria.

[0237] If the evaluation result meets the Multi-Rx operation criteria, the UE reactivates Multi-Rx operation. For example, if the UE is located at the edge of the serving cell and / or the signal quality of the UE's serving cell is below a first threshold, the Multi-Rx operation criteria are met, and the UE reactivates Multi-Rx operation and / or performs the first measurement.

[0238] In some embodiments, if the evaluation result meets the Multi-Rx operation criteria, the UE also updates the UAI report, for example, the UE sends a second UAI. The second UAI carries an indication of the tendency state for Multi-Rx operation, or the second UAI carries indication information for reactivating Multi-Rx operation.

[0239] If the evaluation result indicates that the Multi-Rx operation criteria are not met, the UE reactivates Single-Rx operation. For example, if the UE is not located at the edge of the serving cell and / or the signal quality of the UE's serving cell is higher than a first threshold, the Multi-Rx operation criteria are not met, and the UE reactivates Single-Rx operation and / or performs a second measurement.

[0240] In some embodiments, if the evaluation result indicates that the Multi-Rx operation criteria are not met, the UE may also update the UAI report, for example, by sending a second UAI. The second UAI carries an indication of a preference for Single-Rx operation, or it carries an indication to reactivate Single-Rx operation.

[0241] In summary, the method provided in this application supports the UE entering a Multi-Rx operation state according to the network device configuration. Upon the UE completing a valid report related to a Multi-Rx operation or the third time interval ending, the UE automatically exits the Multi-Rx operation state, enabling flexible switching between Multi-Rx and Single-Rx operations. This allows for timely adjustment of the UE's measurement behavior, ensuring overall efficiency within the communication system. Furthermore, it supports the UE reassessing whether the Multi-Rx operation criteria are met, and promptly resuming the Multi-Rx operation state if the criteria are satisfied.

[0242] Figure 12 illustrates a flowchart of a communication method provided in an exemplary embodiment of this application. The method is performed by a network device and a UE, and includes at least some of the following steps:

[0243] Step 1201: UE reports capability information.

[0244] The capability information reported by the UE includes: whether the UE supports Multi-Rx operation capability and / or whether the UE supports Multi-Rx tendency indication capability.

[0245] If the UE supports Multi-Rx operation capability, it means that the UE supports the radio frequency capability of multiple antenna panels and / or the measurement capability of multiple antenna panels. For example, the UR supports performing layer 1 neighbor cell measurement and / or layer 3 neighbor cell measurement using the Multi-Rx chain.

[0246] If the UE supports the Multi-Rx preference indication capability, it means that the UE supports reporting indication information indicating that it prefers Multi-Rx operation.

[0247] In some embodiments, a UE in RRC connected state reports this capability information.

[0248] In some embodiments, the UE reports this capability information when establishing an RRC connection.

[0249] Step 1202: Configure the network device to allow the UE to report or update its preference status.

[0250] In other words, the network device instructs the UE to report or update the tendency status.

[0251] In some embodiments, the network device configures the UE to report tendency information based on Multi-Rx operations (Multi-Rx based L1 / L3 measurement reduction / relaxation / BSF reduction). For example, the network device configures the UE to report the tendency state corresponding to FR2, or configures the UE to report the tendency state corresponding to a frequency band, or configures the UE to report the tendency state corresponding to a cell.

[0252] In some embodiments, the network device configures the UE to update the tendency information of Multi-Rx operations based on Layer 1 and / or Layer 3 measurement reduction / relaxation / BSF reduction. For example, the network device configures the UE to update the tendency state corresponding to FR2, or configures the UE to update the tendency state corresponding to a frequency band, or configures the UE to update the tendency state corresponding to a cell.

[0253] Step 1203: UE sets or updates the preference status in UAI.

[0254] In some embodiments, the UE sets the tendency state in the UAI to either the tendency state for Multi-Rx operation or the tendency state for Single-Rx operation based on the measurement results.

[0255] In some embodiments, the UE updates the tendency state in the UAI to the tendency state of Multi-Rx operation or the tendency state of Single-Rx operation based on the measurement results.

[0256] In some embodiments, the UE determines whether it prefers to operate in Multi-Rx mode based on the measurement results of FR2. Alternatively, the UE determines whether it prefers to operate in Multi-Rx mode based on the measurement results of the band. Alternatively, the UE determines whether it prefers to operate in Multi-Rx mode based on the measurement results of the cell.

[0257] When the orientation state is set or updated to indicate Multi-Rx operation, the UE activates Multi-Rx operation and / or performs the first measurement.

[0258] If the set or updated preference state indicates Single-Rx operation, the UE activates Single-Rx operation and / or performs a second measurement.

[0259] Step 1204: UE starts Timer T1.

[0260] In some embodiments, if the UE has not previously reported UAI, Timer T1 is started.

[0261] In some embodiments, if the UE has not previously reported a UAI carrying a bias state, then Timer T1 is started.

[0262] In some embodiments, if the new tendency state of the UE is different from the previously reported tendency state, then Timer T1 is started.

[0263] Timer T1 includes a third timer. The duration of the third timer represents the maximum duration of the new trend state. If the new trend state indicates a Multi-Rx operation, the duration of the third timer represents the maximum duration of the Multi-Rx operation and / or the maximum duration of the first measurement. If the new trend state indicates a Single-Rx operation, the duration of the third timer represents the maximum duration of the Single-Rx operation and / or the maximum duration of the second measurement. This application does not limit the name of the third timer; by example, the third timer may also be referred to as a new operation timer, a new measurement timer, or a new trend timer.

[0264] In some embodiments, Timer T1 is started periodically.

[0265] In some embodiments, the priority of switching the operation state based on the UAI is higher than the priority of switching the operation state based on the evaluation results of the Multi-Rx operation criteria.

[0266] Step 1205: UE reports UAI.

[0267] In some embodiments, the UE starts Timer T1 and reports the UAI obtained in step 1203.

[0268] In some embodiments, the UE periodically reports the UAI.

[0269] In some embodiments, step 1205 and step 1204 are executed simultaneously, or step 1205 is executed after step 1204, or step 1204 is executed after step 1205.

[0270] In summary, the method provided in this application supports the UE in flexibly switching between Multi-Rx and Single-Rx operations by combining the reporting of UAI carrying a preference state, thereby adjusting the measurement behavior on the UE side in a timely manner and ensuring the overall efficiency within the communication system. If the preference state carried by the UAI reported by the UE indicates Single-Rx operation, the UE can automatically exit the Multi-Rx operation state. If the preference state carried by the UAI reported by the UE indicates Multi-Rx operation, the UE can automatically enter the Multi-Rx operation state.

[0271] Figure 13 illustrates a flowchart of a communication method provided in an exemplary embodiment of this application. The method is performed by a network device and a UE, and includes at least some of the following steps:

[0272] Step 1301: UE reports capability information.

[0273] The capability information reported by the UE includes: whether the UE supports Multi-Rx operation capability and / or whether the UE supports Multi-Rx tendency indication capability.

[0274] If the UE supports Multi-Rx operation capability, it means that the UE supports the radio frequency capability of multiple antenna panels and / or the measurement capability of multiple antenna panels. For example, the UR supports performing layer 1 neighbor cell measurement and / or layer 3 neighbor cell measurement using the Multi-Rx chain.

[0275] If the UE supports the Multi-Rx preference indication capability, it means that the UE supports reporting indication information indicating that it prefers Multi-Rx operation.

[0276] In some embodiments, a UE in RRC connected state reports this capability information.

[0277] In some embodiments, the UE reports this capability information when establishing an RRC connection.

[0278] Step 1302: Configure Multi-Rx operating guidelines for network devices.

[0279] Multi-Rx operating criteria include one or more of the following: the UE is located at the edge of the serving cell, and the signal quality of the UE's serving cell is below a first threshold. Signal quality is represented by RSRP, RSRQ, or SINR.

[0280] In some embodiments, the Multi-Rx operating criteria are configured according to FR2, or according to frequency band, or according to cell group, or according to cell.

[0281] The Multi-Rx operating guidelines can also be understood as guidelines for reducing / relaxing / BSF reduction in layer 1 and / or layer 3 measurements.

[0282] Step 1303: The UE activates Multi-Rx operation or Single-Rx operation based on the evaluation results of the Multi-Rx operation criteria.

[0283] In some embodiments, if the evaluation result indicates that the UE meets the Multi-Rx operation criteria, the UE activates Multi-Rx operation and / or performs the first measurement.

[0284] In some embodiments, if the evaluation result indicates that the UE does not meet the Multi-Rx operation criteria, the UE deactivates Multi-Rx operation and / or performs a second measurement. Alternatively, if the evaluation result indicates that the UE does not meet the Multi-Rx operation criteria, the UE deactivates Multi-Rx operation and / or stops measurement.

[0285] Step 1304: UE reports UAI.

[0286] In some embodiments, when the UE activates Multi-Rx operation, it also reports a UAI, which carries indication information for activating Multi-Rx operation.

[0287] In some embodiments, when the UE deactivates the Multi-Rx operation, it also reports a UAI, which carries indication information for deactivating the Multi-Rx operation.

[0288] In some embodiments, if the evaluation result of the UE's current Multi-Rx operation criteria differs from the status indication information carried in the previously reported UAI, the UE updates the reported UAI, which carries the indication information of the new operation status. For example, if the UE's previously reported UAI carried indication information for activating Multi-Rx operation, and the current evaluation result indicates that the UE does not meet the Multi-Rx operation criteria, then the UE updates the reported UAI, carrying indication information for deactivating Multi-Rx operation. Conversely, if the UE's previously reported UAI carried indication information for deactivating Multi-Rx operation, and the current evaluation result indicates that the UE meets the Multi-Rx operation criteria, then the UE updates the reported UAI, carrying indication information for activating Multi-Rx operation.

[0289] In summary, the method provided in this application supports the UE in flexibly switching between Multi-Rx and Single-Rx operations by combining the evaluation of Multi-Rx operation criteria, thereby adjusting the measurement behavior on the UE side in a timely manner and ensuring the overall efficiency within the communication system. The UE determines the information carried by the UAI based on the evaluation results of the Multi-Rx operation criteria.

[0290] Figure 14 illustrates a flowchart of a communication method provided in an exemplary embodiment of this application. The method is performed by a network device and a UE, and includes at least some of the following steps:

[0291] Step 1401: UE reports capability information.

[0292] The capability information reported by the UE includes: whether the UE supports Multi-Rx operation capability and / or whether the UE supports Multi-Rx tendency indication capability.

[0293] If the UE supports Multi-Rx operation capability, it means that the UE supports the radio frequency capability of multiple antenna panels and / or the measurement capability of multiple antenna panels. For example, the UR supports performing layer 1 neighbor cell measurement and / or layer 3 neighbor cell measurement using the Multi-Rx chain.

[0294] If the UE supports the Multi-Rx preference indication capability, it means that the UE supports reporting indication information indicating that it prefers Multi-Rx operation.

[0295] In some embodiments, a UE in RRC connected state reports this capability information.

[0296] In some embodiments, the UE reports this capability information when establishing an RRC connection.

[0297] Step 1402: Configure the network device to report whether the UE meets the Multi-Rx operation criteria.

[0298] This can also be understood as the network device instructing the UE to report whether the Multi-Rx operating criteria are met.

[0299] Multi-Rx operation criteria are configured by network devices or agreed upon by communication protocols. For example, Multi-Rx operation criteria may include one or more of the following: the UE is located at the edge of the serving cell, and the signal quality of the UE's serving cell is below a first threshold, where signal quality is represented by RSRP, RSRQ, or SINR. Another example is that the network device configuration or protocol may stipulate that the UE performs Multi-Rx operation based on a relaxation measurement of BSF reduction at Layer 1 and / or Layer 3.

[0300] In some embodiments, the Multi-Rx operating criteria are configured according to FR2, or according to frequency band, or according to cell group, or according to cell.

[0301] Step 1403: UE evaluates Multi-Rx operating criteria.

[0302] Upon receiving a signaling instruction to report whether the Multi-Rx operation criteria are met, the UE begins to assess whether the Multi-Rx operation criteria are met.

[0303] Step 1404: Report the UAI carrying information on criterion fulfillment.

[0304] In some embodiments, the UE determines whether it has previously reported a UAI carrying criterion fulfillment information, or whether the current criterion fulfillment information is the same as the previously reported criterion fulfillment information. The criterion fulfillment information indicates whether the UE meets the Multi-Rx operation criteria. For example, when the bit value of the criterion fulfillment information is a first value, it indicates that the UE meets the Multi-Rx operation criteria; when the bit value of the criterion fulfillment information is a second value, it indicates that the UE does not meet the Multi-Rx operation criteria. Taking a criterion fulfillment information using 1 bit as an example, the first value is 1 and the second value is 0; or, the first value is 0 and the second value is 1.

[0305] If the UE has not previously reported to the UAI carrying criterion satisfaction information, the UE will report to the UAI carrying criterion satisfaction information. This criterion satisfaction information indicates whether the UE meets or does not meet the Multi-Rx operation criteria.

[0306] If the UE meets the Multi-Rx operation criteria, the UE activates Multi-Rx operation and / or performs the first measurement.

[0307] If the UE does not meet the Multi-Rx operation criteria, the UE deactivates Multi-Rx operation and / or performs a second measurement. Alternatively, if the UE does not meet the Multi-Rx operation criteria, the UE deactivates Multi-Rx operation and / or stops measurement.

[0308] If the UE's current criterion fulfillment information (i.e., the new criterion fulfillment information) is different from the previously reported criterion fulfillment information (i.e., the old criterion fulfillment information), the UE reports a UAI carrying the current criterion fulfillment information and enters the operation state corresponding to the current criterion fulfillment information.

[0309] For example, if the previously reported criterion fulfillment information indicates that the Multi-Rx operation criteria are met, while the current criterion fulfillment information indicates that the Multi-Rx operation criteria are not met, then the UE will deactivate the Multi-Rx operation and activate the Single-Rx operation. During the activation of the Single-Rx operation, a second measurement will be performed or the measurement will be stopped. The second measurement may include, for example, neighboring cell measurements in Layer 1 and / or Layer 3.

[0310] For example, if the previously reported criterion fulfillment information indicates that the Multi-Rx operation criteria were not met, and the current criterion fulfillment information indicates that the Multi-Rx operation criteria are met, then the UE deactivates Single-Rx operation and activates Multi-Rx operation. During the activation of Multi-Rx operation, a first measurement is performed. The first measurement may include, for example, neighbor cell relaxation measurements in Layer 1 and / or Layer 3, where the measurement duration of the first measurement is greater than the measurement duration of the second measurement and / or the BSF of the first measurement is less than the BSF of the second measurement.

[0311] Step 1405: UE starts Timer T2.

[0312] Timer T2 includes a third timer. The duration of the third timer represents the maximum duration during which an exit from the old state and entry into the new state are permitted. If the old state is a Single-Rx operation state and the new state is a Multi-Rx operation state, then the duration of the third timer represents the maximum duration during which an exit from the Single-Rx operation state and entry into the Multi-Rx operation state are permitted. If the old state is a Multi-Rx operation state and the new state is a Single-Rx operation state, then the duration of the third timer represents the maximum duration during which an exit from the Multi-Rx operation state and entry into the Single-Rx operation state are permitted. This application does not limit the name of the third timer; for example, the third timer may also be called a new operation timer, a new measurement timer, or a new tendency timer.

[0313] In some embodiments, step 1405 and step 1404 are executed simultaneously, or step 1405 is executed after step 1404, or step 1404 is executed after step 1405.

[0314] In summary, the method provided in this application supports UE evaluation of Multi-Rx operation criteria and reports UAI carrying criterion satisfaction information according to the instructions of the network device, thereby realizing flexible switching between Multi-Rx operation and Single-Rx operation, and thus adjusting the measurement behavior on the UE side in a timely manner to ensure the overall efficiency within the communication system.

[0315] Figure 15 illustrates a flowchart of a communication method provided in an exemplary embodiment of this application. The method is performed by a network device and a UE, and includes at least some of the following steps:

[0316] Step 1501: UE reports capability information.

[0317] The capability information reported by the UE includes: whether the UE supports Multi-Rx operation capability and / or whether the UE supports Multi-Rx tendency indication capability.

[0318] If the UE supports Multi-Rx operation capability, it means that the UE supports the radio frequency capability of multiple antenna panels and / or the measurement capability of multiple antenna panels. For example, the UR supports performing layer 1 neighbor cell measurement and / or layer 3 neighbor cell measurement using the Multi-Rx chain.

[0319] If the UE supports the Multi-Rx preference indication capability, it means that the UE supports reporting indication information indicating that it prefers Multi-Rx operation.

[0320] In some embodiments, a UE in RRC connected state reports this capability information.

[0321] In some embodiments, the UE reports this capability information when establishing an RRC connection.

[0322] Step 1502: Configure Multi-Rx operating guidelines for network devices.

[0323] Multi-Rx operation criteria include one or more of the following: whether to activate Multi-Rx operation, the signal quality threshold for activating Multi-Rx operation, and the signal quality threshold for deactivating Multi-Rx operation. Signal quality is represented by RSRP, RSRQ, or SINR.

[0324] In some embodiments, the Multi-Rx operating criteria are configured according to FR2, or according to frequency band, or according to cell group, or according to cell.

[0325] The Multi-Rx operating guidelines can also be understood as guidelines for reducing / relaxing / BSF reduction in layer 1 and / or layer 3 measurements.

[0326] Step 1503: The UE starts Timer T3 or Timer T4 based on the evaluation results of the Multi-Rx operation criteria.

[0327] In some embodiments, if the evaluation result indicates that the UE meets the Multi-Rx operation criteria, the UE activates Multi-Rx operation and / or performs the first measurement, and starts Timer T3. If Timer T4 is running before Timer T3 is started, Timer T4 is stopped when Timer T3 is started. After Timer T3 times out, the UE again determines whether the Multi-Rx operation criteria are met and repeats step 1403.

[0328] In some embodiments, if the evaluation result indicates that the UE does not meet the Multi-Rx operation criteria, the UE activates Single-Rx operation and / or performs a second measurement, and starts Timer T4. If Timer T3 is running before Timer T4 is started, Timer T3 is stopped when Timer T4 is started. After Timer T4 times out, the UE again determines whether the Multi-Rx operation criteria are met, without restarting Timer T4, and repeats step 1403.

[0329] In some embodiments, if the evaluation result indicates that the UE does not meet the Multi-Rx operation criteria, the UE activates Single-Rx operation and / or stops measurement, and starts Timer T4. If Timer T3 is running before Timer T4 is started, Timer T3 is stopped when Timer T4 is started. After Timer T4 times out, the UE again determines whether the Multi-Rx operation criteria are met, without restarting Timer T4, and repeats step 1403.

[0330] Timer T3 includes a second timer. The duration of the second timer represents the maximum duration of the Multi-Rx operation and / or the maximum duration of the first measurement. Timer T3 is defined by the communication protocol or configured by the network device; for example, the network device may configure Timer T3 when configuring the Multi-Rx operation guidelines. This application does not limit the name of the second timer; for example, the second timer may also be called a Multi-Rx timer, a relaxation measurement timer, or a BSF Reduction measurement timer.

[0331] Timer T4 includes a first timer. The duration of the first timer represents the maximum duration of Single-Rx operation and / or the maximum duration of the second measurement. Timer T4 is defined by the communication protocol or configured by the network device; for example, the network device may configure Timer T4 when configuring Multi-Rx operation guidelines. This application does not limit the name of the first timer; for example, the first timer may also be called a Single-Rx timer, a normal measurement timer, or a conventional measurement timer.

[0332] In summary, the method provided in this application supports the UE in evaluating Multi-Rx operation criteria and starting a timer, and also supports re-evaluating Multi-Rx operation criteria when the timer expires. By starting and ending the timer, the method enables flexible switching between Multi-Rx operation and Single-Rx operation, thereby adjusting the measurement behavior on the UE side in a timely manner and ensuring the overall efficiency within the communication system.

[0333] Furthermore, regardless of whether the UE is in RRC connected state, RRC inactive state, or RRC idle state, the UE can maintain a timer and promptly re-enter the Multi-Rx operation state or re-enter the Single-Rx operation state based on the evaluation results of the Multi-Rx operation criteria after the timer expires. Therefore, the embodiment shown in Figure 15 is applicable to UEs in RRC connected state, RRC inactive state, or RRC idle state.

[0334] Figure 16 illustrates a flowchart of a communication method provided in an exemplary embodiment of this application. The method is performed by a network device and a UE, and includes at least some of the following steps:

[0335] Step 1601: UE reports capability information.

[0336] The capability information reported by the UE includes: whether the UE supports Multi-Rx operation capability and / or whether the UE supports Multi-Rx tendency indication capability.

[0337] If the UE supports Multi-Rx operation capability, it means that the UE supports the radio frequency capability of multiple antenna panels and / or the measurement capability of multiple antenna panels. For example, the UR supports performing layer 1 neighbor cell measurement and / or layer 3 neighbor cell measurement using the Multi-Rx chain.

[0338] If the UE supports the Multi-Rx preference indication capability, it means that the UE supports reporting indication information indicating that it prefers Multi-Rx operation.

[0339] In some embodiments, a UE in RRC connected state reports this capability information.

[0340] In some embodiments, the UE reports this capability information when establishing an RRC connection.

[0341] Step 1602: Configure Multi-Rx operating guidelines for network devices.

[0342] Multi-Rx operation criteria include one or more of the following: whether to activate Multi-Rx operation, the signal quality threshold for activating Multi-Rx operation, and the signal quality threshold for deactivating Multi-Rx operation. Signal quality is represented by RSRP, RSRQ, or SINR.

[0343] In some embodiments, the Multi-Rx operating criteria are configured according to FR2, or according to frequency band, or according to cell group, or according to cell.

[0344] The Multi-Rx operating guidelines can also be understood as guidelines for reducing / relaxing / BSF reduction in layer 1 and / or layer 3 measurements.

[0345] Step 1603: If the evaluation result meets the Multi-Rx operation criteria, the UE activates Multi-Rx operation.

[0346] If the evaluation result indicates that the UE meets the Multi-Rx operation criteria, the UE activates Multi-Rx operation and / or performs the first measurement, and starts Timer T3. Timer T3 includes a second timer. The duration of the second timer represents the maximum duration of the Multi-Rx operation and / or the maximum duration of the first measurement. Timer T3 is defined by the communication protocol or configured by the network device; for example, the network device may configure Timer T3 when configuring the Multi-Rx operation criteria.

[0347] For example, the first measurement includes adjacent region relaxation measurements of layer 1 and / or layer 3 for BSF reduction. For example, the first measurement includes adjacent region relaxation measurements of layer 1 and / or layer 3 for RLM / BFD.

[0348] Step 1604: Deactivate Multi-Rx operation.

[0349] In some embodiments, the UE deactivates the Multi-Rx operation when Timer T3 ends. Alternatively, the UE deactivates the Multi-Rx operation after Timer T3 times out and a second duration has elapsed. The second duration is represented by time or time units. For example, the second duration is t2 seconds (s), or t2 milliseconds (ms), or t2 microseconds (μs), or t2 time units, where t2 > 0. For example, the second duration is t2 symbols, or t2 symbol groups, or t2 subframes, or t2 frames, or t2 time slots, or t2 sub-time slots. The second duration is configured by the network device, agreed upon by the communication protocol, or determined autonomously by the UE.

[0350] In some embodiments, the UE deactivates Multi-Rx operation before the timer T3 expires. For example, if the UE's preferred state changes to Single-Rx operation, or the UE enters an overheating state, or the UE enters a power-saving state, or the UE experiences an RLF (Restricted Level Default), or the UE no longer meets the Multi-Rx operation criteria before the timer T3 expires, the UE deactivates Multi-Rx operation early. Alternatively, if the UE reports a UAI (User Information Acknowledging Indicator) indicating a preferred Single-Rx operation, or a UAI indicating overheating, or a UAI indicating power saving, or a UAI indicating an RLF, or a UAI indicating failure to meet the Multi-Rx operation criteria before the timer T3 expires, the UE deactivates Multi-Rx operation early.

[0351] In some embodiments, during the deactivation of Multi-Rx operation, the UE does not perform measurements, or the UE performs a second measurement. Exemplarily, the second measurement includes normal neighbor cell measurements of Layer 1 and / or Layer 3, which may also be referred to as conventional neighbor cell measurements of Layer 1 and / or Layer 3.

[0352] The BSF corresponding to the first measurement is less than the BSF corresponding to the second measurement, and / or the measurement duration corresponding to the first measurement is greater than the measurement duration corresponding to the second measurement.

[0353] In some embodiments, the UE stops evaluating the Multi-Rx operation criteria during the deactivation period of Multi-Rx operation and / or the activation period of Single-Rx operation.

[0354] Step 1605: UE re-evaluates Multi-Rx operating guidelines.

[0355] In some embodiments, the UE autonomously reassesses whether it meets the Multi-Rx operating criteria. For example, when entering an overheating state or a power-saving state, the UE autonomously reassesses whether it meets the Multi-Rx operating criteria. Another example is when an RLF (Recurrent Leakage Fault) occurs, the UE autonomously reassesses whether it meets the Multi-Rx operating criteria.

[0356] In some embodiments, the UE reassesses whether it meets the Multi-Rx operation criteria based on triggering signaling from the network device. For example, the UE reassesses whether it meets the Multi-Rx operation criteria upon receiving configuration signaling for Multi-Rx operation. Alternatively, the UE reassesses whether it meets the Multi-Rx operation criteria upon receiving configuration signaling for a first measurement. Another example is the UE reassessing whether it meets the Multi-Rx operation criteria upon receiving configuration signaling for group-based beam reporting. Yet another example is the UE reassessing whether it meets the Multi-Rx operation criteria upon receiving indication signaling for reporting a UAI.

[0357] In some embodiments, if a third condition is met, the UE re-evaluates whether the Multi-Rx operation criteria are met. The third condition includes one or more of the following: a first timer times out, the duration of which represents the maximum duration of a Single-Rx operation and / or the maximum duration of a second measurement; the first timer times out and a fourth duration has elapsed; a second timer times out, the duration of which represents the maximum duration of a Multi-Rx operation and / or the maximum duration of a first measurement; the second timer times out and a fourth duration has elapsed; a third timer times out, the duration of which represents the maximum duration of a new Rx operation (i.e., an Rx operation activated during the start of the third timer) and / or the maximum duration of a new measurement (i.e., a measurement performed during the start of the third timer); the third timer times out and a fourth duration has elapsed; and a fifth duration ends, the fifth duration representing the total time for the UE to complete one measurement and one evaluation of the Multi-Rx operation criteria.

[0358] The relevant content of the third condition is described in step 660, and will not be repeated here.

[0359] In some embodiments, the UE reactivates Multi-Rx operation if the reassessment result meets the Multi-Rx operation criteria. For example, if the UE is located at the edge of the serving cell and / or the signal quality of the UE's serving cell is below a first threshold, the Multi-Rx operation criteria are met, and the UE reactivates Multi-Rx operation and / or performs the first measurement.

[0360] In some embodiments, if the reassessment result indicates that the Multi-Rx operation criteria are met, the UE also updates the UAI report, for example, by sending a second UAI. The second UAI carries an indication of the preference state for Multi-Rx operation, or it carries indication information for reactivating Multi-Rx operation.

[0361] In some embodiments, if the reassessment result indicates that the Multi-Rx operation criteria are not met, the UE reactivates Single-Rx operation. For example, if the UE is not located at the edge of the serving cell and / or the signal quality of the UE's serving cell is higher than a first threshold, the Multi-Rx operation criteria are not met, and the UE reactivates Single-Rx operation and / or performs a second measurement.

[0362] In some embodiments, if the reassessment result indicates that the Multi-Rx operation criteria are not met, the UE also updates the UAI report, for example, the UE sends a second UAI. The second UAI carries an indication of a preference for Single-Rx operation, or the second UAI carries indication information for reactivating Single-Rx operation.

[0363] In summary, the method provided in this application allows the UE to stop evaluating Multi-Rx operation criteria after exiting the Multi-Rx operation state. The UE can then autonomously determine or be triggered by the network device to restart the evaluation of the Multi-Rx operation criteria, and the Multi-Rx operation state can be restored promptly if the criteria are met. This application provides a concrete and feasible solution for exiting and re-entering the Multi-Rx operation state, enabling flexible switching between Multi-Rx and Single-Rx operations, thereby adjusting the UE's measurement behavior in a timely manner and ensuring the overall efficiency of the communication system.

[0364] Figure 17 illustrates a flowchart of a communication method provided in an exemplary embodiment of this application. The method is performed by a network device and a UE, and includes at least some of the following steps:

[0365] Step 1701: UE reports capability information.

[0366] The capability information reported by the UE includes: whether the UE supports Multi-Rx operation capability and / or whether the UE supports Multi-Rx tendency indication capability.

[0367] If the UE supports Multi-Rx operation capability, it means that the UE supports the radio frequency capability of multiple antenna panels and / or the measurement capability of multiple antenna panels. For example, the UR supports performing layer 1 neighbor cell measurement and / or layer 3 neighbor cell measurement using the Multi-Rx chain.

[0368] If the UE supports the Multi-Rx preference indication capability, it means that the UE supports reporting indication information indicating that it prefers Multi-Rx operation.

[0369] In some embodiments, a UE in RRC connected state reports this capability information.

[0370] In some embodiments, the UE reports this capability information when establishing an RRC connection.

[0371] Step 1702: The UE sends a request message, which is used to request a change in the operation state.

[0372] For example, if the UE is currently in Multi-Rx operation mode, and the UE sends a request to switch to Single-Rx operation mode.

[0373] For example, if the UE is currently in Single-Rx operation mode, the UE sends a request to switch to Multi-Rx operation mode.

[0374] Step 1703: The network device sends a response message, which carries configuration information for time duration 1.

[0375] In some embodiments, the response information carries configuration information for time duration 1. Time duration 1 is sufficient for the UE to complete at least one full measurement period.

[0376] Step 1704: During time duration 1, the UE is in a new operation state.

[0377] During time duration 1, the UE maintains the new operating state requested by the request information; that is, the UE maintains the new preferred state until time duration 1 ends.

[0378] If the new operation state is Multi-Rx operation, the UE performs the first measurement during time duration 1.

[0379] If the new operation status is Single-Rx operation, the UE will perform a second measurement or not perform a measurement during time duration 1.

[0380] Step 1705: After time duration 1 ends, the UE returns to the old operation state.

[0381] After time duration 1 ends, the UE returns to the old operating state before the handover request, that is, the UE returns to the old preferred state, and the UE re-evaluates the Multi-Rx operating criteria.

[0382] In summary, the method provided in this application supports the UE to actively send request information for switching operation status, and realizes flexible switching between Multi-Rx operation and Single-Rx operation based on the response information from the network side, so that the UE's measurement behavior conforms to the actual communication environment and network side instructions.

[0383] Figure 18 illustrates a flowchart of a communication method provided in an exemplary embodiment of this application. The method is performed by a network device and a UE, and includes at least some of the following steps:

[0384] Step 1801: UE reports capability information.

[0385] The capability information reported by the UE includes: whether the UE supports Multi-Rx operation capability and / or whether the UE supports Multi-Rx tendency indication capability.

[0386] If the UE supports Multi-Rx operation capability, it means that the UE supports the radio frequency capability of multiple antenna panels and / or the measurement capability of multiple antenna panels. For example, the UR supports performing layer 1 neighbor cell measurement and / or layer 3 neighbor cell measurement using the Multi-Rx chain.

[0387] If the UE supports the Multi-Rx preference indication capability, it means that the UE supports reporting indication information indicating that it prefers Multi-Rx operation.

[0388] In some embodiments, a UE in RRC connected state reports this capability information.

[0389] In some embodiments, the UE reports this capability information when establishing an RRC connection.

[0390] Step 1802: The UE sends a request message, which is used to request a change in the operation status.

[0391] For example, if the UE is currently in Multi-Rx operation mode, and the UE sends a request to switch to Single-Rx operation mode.

[0392] For example, if the UE is currently in Single-Rx operation mode, the UE sends a request to switch to Multi-Rx operation mode.

[0393] Step 1803: The network device sends a response message.

[0394] In some embodiments, the response information carries indication information indicating whether or not to agree to the request.

[0395] Step 1804: The UE receives the response information and starts Timer T2.

[0396] Timer T2 includes a third timer. The duration of the third timer represents the maximum allowed duration for exiting the old state and entering the new state. If the old state is a Single-Rx operation state and the new state is a Multi-Rx operation state, then the duration of the third timer represents the maximum allowed duration for exiting the Single-Rx operation state and entering the Multi-Rx operation state. If the old state is a Multi-Rx operation state and the new state is a Single-Rx operation state, then the duration of the third timer represents the maximum allowed duration for exiting the Multi-Rx operation state and entering the Single-Rx operation state.

[0397] During the timer T2 period, the UE maintains the new operating state requested by the request information, that is, the UE maintains the new preferred state until the timer T2 ends.

[0398] If the new operation state is Multi-Rx operation, the UE performs the first measurement during the timing of Timer T2. If the new operation state is Single-Rx operation, the UE performs the second measurement or does not perform a measurement during the timing of Timer T2.

[0399] Step 1805: After Timer T2 ends, the UE returns to the old operation state.

[0400] After Timer T2 ends, the UE returns to the old operating state before the handover request, that is, the UE returns to the old preferred state, and the UE re-evaluates the Multi-Rx operating criteria.

[0401] In summary, the method provided in this application embodiment supports the UE to actively send request information for switching operation status and start a timer based on the response information from the network side, thereby realizing flexible switching between Multi-Rx operation and Single-Rx operation, so that the UE's measurement behavior conforms to the actual communication environment and network side instructions.
