Description

Method, device and communication system for measuring relaxation Technical Field The embodiments of the present application relate to the field of communication technologies. Background Art The terminal device is able to evaluate the downlink radio link quality of a serving cell based on reference signals to detect beam failure. This applies to PCell (primary cell) in SA (standalone networking), NR-DC (new radio-new radio dual connectivity) or NE-DC (new radio-evolved universal terrestrial radio access dual connectivity) operation mode, PSCell (primary secondary cell) in NR-DC or EN-DC (evolved universal terrestrial radio access-new radio dual connectivity) operation mode, and SCell (secondary cell) in SA, NR-DC, NE-DC or EN-DC operation mode. SSB (synchronization signal block) based beam failure detection is based on the SSB associated with the initial DL BWP (downlink bandwidth part) and can only be configured for the initial DL BWPs and DL BWPs including the SSB associated with the initial DL BWP. For other DL BWPs, beam failure detection is performed only based on CSI-RS (synchronization signal block / channel state information reference signal). The terminal is not required to perform beam failure detection outside the activated DL BWP. Beam failure is detected by counting the number of beam failure instances indicated by the lower layers to the MAC (Media Access Control) entity. In addition, in multi-TRP (transmit receive point) operation, a serving cell can schedule terminal devices (e.g., UE) from 2 TRPs to provide better coverage, reliability and / or data rate for PDSCH (physical downlink shared channel), PDCCH (physical downlink control channel), PUSCH (physical uplink shared channel) and PUCCH (physical uplink control channel). For beam failure detection under multi-TRP operation, the network device (e.g., gNB) configures 2 or more groups of beam failure detection reference signals for the terminal device (e.g., UE), one group for each TRP. Before the configured timer expires, when the beam failure embodiment indication associated with a set of beam failure detection reference signals from the physical layer reaches the configured threshold, the UE declares the beam failure of the corresponding TRP. It should be noted that the above introduction to the technical background is only for the convenience of providing a clear and complete description of the technical solutions of the present application and for the convenience of understanding by those skilled in the art. It cannot be considered that the above technical solutions are well known to those skilled in the art simply because they are described in the background technology section of the present application. Summary of the invention In Rel-17, the measurement relaxation of BFD (Beam Failure Detection) is introduced to ensure energy saving of terminal equipment. In addition, beam failure detection for multiple TRPs is also introduced. The inventor of the present application has found that when a serving cell is configured with multiple TRPs, there are at least the following problems: 1. The current BFD measurement relaxation state is based on the service cell report. When the BFD measurement relaxation is executed, the indication is 1, otherwise the indication is 0. In the case of multiple TRPs, the current mechanism cannot determine the reporting content. This may cause different understandings between the network equipment and the terminal equipment, resulting in inappropriate operation of the network equipment on the mobility of the terminal equipment, resulting in service interruption. 2. The relaxation of BFD measurement is performed based on cell-level measurement evaluation. In the case of multiple TRPs, one TRP with good quality and another TRP with poor quality, the terminal may relax the BFD measurement of the TRP with poor quality, causing the network to operate the terminal mobility inappropriately, resulting in service interruption. In order to solve at least one of the above problems, the embodiments of the present application provide a method, an apparatus and a communication system for measurement relaxation, which can avoid inappropriate operation of a network device on a terminal device, thereby avoiding service interruption.

The high-level signaling may also be, for example, an F1-C signaling, or an F1AP protocol. However, the present application is not limited thereto. The terminal relaxes the BFD measurement to ensure the terminal energy saving. When configured, the terminal determines whether it is in a low mobility state and / or whether the radio link quality of its serving cell is better than a threshold. The terminal determines whether it is in a low mobility state as follows: The terminal determines whether the quality of the radio link of its serving cell is better than a threshold as follows: The criteria of low mobility and good serving cell quality are provided by dedicated signaling. Only when the criteria of relaxation measurement of low mobility and / or good serving cell quality are met, the terminal is allowed to perform BFD relaxation. RLM and BFD relaxation can be activated / deactivated separately, and BFD can be activated / deactivated on a per-serving cell basis. If configured to execute, if the terminal changes its BFD relaxation state while meeting the terminal minimum requirements, the terminal will trigger the reporting of its BFD relaxation state through UE assistance information. The following IE is used to configure the terminal to report the BFD relaxation status: Based on the above configuration, the terminal determines whether to report the BFD relaxation status. The process is as follows: When configured to do so, and when the relaxed state of BFD measurements in RRC_CONNECTED changes, a UE capable of relaxing BFD measurements for a cell group in RRC_CONNECTED state shall initiate the following procedure to provide an indication of the relaxed state of its BFD measurements: The following timers are used to control reporting: The settings for reporting content are as follows: The specific news is as follows: The transmission of UE assistance information message is as follows: The embodiments of this application are based on the following scenarios: The service cell of the terminal device is configured with more than two beam failure detection reference signal (BFD-RS) groups, for example, two BFD-RS groups; or the terminal device is configured with carrier aggregation, and some of the service cells are configured with beam failure detection, some of these service cells are configured with more than two BFD-RS groups, that is, beam failure detection of the BFD-RS groups is performed, and some cells are not configured with more than two BFD-RS groups, that is, beam failure detection of the service cells is performed. For example, a cell is configured with more than two BFD-RS groups including: a serving cell is configured with failureDetectionSet1-r17 and failureDetectionSet2-r17. For example, a terminal is configured with at least two serving cells for carrier aggregation, where cell 1 (special cell or secondary cell) is configured with beam failure detection and more than two BFD-RS groups; cell 2 (secondary cell) is configured with beam failure detection and no more than two BFD-RS groups are configured. The terminal device may also be configured with cell 3. For example, the terminal device performs beam failure detection on each BFD-RS group of cell 1, and performs beam failure detection on the serving cell of cell 2. Embodiments of the first aspect An embodiment of the first aspect of the present application provides a method for measuring relaxation, which is applied to a terminal device, for example, the terminal device 102 in FIG. 1 . Fig. 2 is a schematic diagram of a method for measuring relaxation according to an embodiment of the first aspect. As shown in Fig. 2, the method for measuring relaxation includes: Operation 201: For a service cell configured with more than two beam failure detection reference signal (BFD-RS) groups, the terminal device does not perform measurement relaxation of beam failure detection (BFD); or, for a service cell not configured with more than two beam failure detection reference signal (BFD-RS) groups, the terminal device performs measurement relaxation of beam failure detection (BFD). For example, in operation 201, BFD relaxation is not performed for a serving cell configured with two BFD-RS groups; or, BFD relaxation is performed only for a serving cell not configured with two BFD-RS groups. Through the embodiments of the first aspect, for the case of multiple TRPs, the network device and the terminal device can have the same understanding of the measurement relaxation of BFD, thereby avoiding inappropriate operation of the network device on the mobility of the terminal device, thereby avoiding service interruption. In the present application, operation 201 may be implemented by at least one of the following schemes 1-1, 1-2, and 1-3. Solution 1-1, In solution 1-1, the terminal device does not perform measurement relaxation of beam failure detection (BFD), including: measurement relaxation of beam failure detection (BFD) is disabled. Disabling may mean not allowing, deactivating, etc. In solution 1-1, the terminal device performs measurement relaxation of beam failure detection (BFD), including: measurement relaxation of beam failure detection (BFD) is enabled. Here, enabled may have the meanings of allowed, activated, enabled, etc. In at least one embodiment of scheme 1-1, for a service cell configured with two BFD-RS groups, BFD measurement relaxation is deactivated (disabled); or, BFD measurement relaxation is enabled (enabled) only for a service cell not configured with two BFD-RS groups. For example, the existence condition or domain description of a first parameter related to a low mobility criterion and / or a second parameter related to a good cell quality criterion may be changed. The first parameter may be lowMobilityEvaluationConnected, and the second parameter may be goodServingCellEvaluationBFD. In addition, the second parameter may be a second parameter for a special cell and / or a secondary cell. Among them, the existence conditions or domain descriptions of the first parameter (lowMobilityEvaluationConnected) related to the low mobility standard are changed, including: the service cell is a special cell, and when there is a first service cell in the cell group where the service cell is located that is not configured with more than two beam failure detection reference signal (BFD-RS) groups, the measurement relaxation of beam failure detection (BFD) is disabled or the measurement relaxation of beam failure detection (BFD) is enabled. Specifically, the existence condition of IE (Information Element) is modified, and the corresponding standard may be: For (1) lowMobilityEvaluationConnected, the criteria are shown in Table 1. Table 1 Or replace "failureDetectionSet1-r17 and failureDetectionSet2-r17 are included" with: "2 BFD RS set are configured"; Or change the Explanation part to "The field is optionally present,Need R if failureDetectionSet1-r17 and failureDetectionSet2-r17 are not configured; otherwise it is absent,Need R.". For (2) goodServingCellEvaluationBFD, the standards are shown in Table 2. Table 2 Or replace "failureDetectionSet1-r17 and failureDetectionSet2-r17 are included" with: "2 BFD RS set are configured"; Or change the Explanation part to "The field is optionally present,Need R if failureDetectionSet1-r17 and failureDetectionSet2-r17 are not configured; otherwise it is absent,Need R." Modify the domain description of IE. The corresponding standard is, for example: For (1) lowMobilityEvaluationConnected, the standard is shown in Table 3. Table 3 Or the condition can be changed to “if NR PSCell without mTRP”. For (2) goodServingCellEvaluationBFD, the standards are shown in Table 4. Table 4 Or change it to “this SCell / SpCell without mTRP”. For another example, it can also be described in the process description of TS38.300 or TS38.331 to implement solution 1-1. Specifically, it is described in TS38.300 and the corresponding standards are shown in Table 5. Table 5 Or add a description like this: “RLM and BFD relaxation may be enabled if there is no serving cell with mTRP.” can be changed to “RLM and BFD relaxation will be disabled if any serving cell with mTRP is configured.” The process description of TS38.331 is described in Table 6. Table 6 Alternatively, for each of the above parameters, add after “if the SpCellConfig contains the…”: “and if failureDetectionSet1-r17 and failureDetectionSet2-r17 are not configured for this SpCell”. Solution 1-2 In scheme 1-2, measurement relaxation of beam failure detection (BFD) is not performed, including: whether the measurement relaxation criteria of beam failure detection (BFD) on the serving cell are met is not evaluated. In scheme 1-2, measurement relaxation of beam failure detection (BFD) is performed, including: evaluating whether a measurement relaxation criterion of beam failure detection (BFD) on the serving cell is met. For example, for a serving cell configured with two BFD-RS groups: whether the relaxed measurement standard is met is not evaluated; or, only whether the relaxed measurement standard is met on a serving cell not configured with two BFD-RS groups is evaluated. In scheme 1-2, whether the relaxation criteria are met is measured, including: whether the low mobility criteria are met, for example, refer to 5.7.13.1 of TS38.331; and / or whether the good cell quality criteria are met, for example, refer to 5.7.13.2 of TS38.331. Among them, whether the low mobility standard is met includes: when there are more than two (for example, 2) beam failure detection reference signal (BFD-RS) groups that are not configured in the cell group where the service cell is located, evaluating whether the low mobility standard is met. In at least one embodiment of scheme 1-2, scheme 1-2 may be implemented by modifying 5.7.13 in TS 38.331 or TS 38.300. Specifically, it is described in TS38.300 and the corresponding standards are shown in Table 7. Table 7 The process description of TS38.331 states that the corresponding standards can be shown in Table 8. Table 8 Alternatively, replace with "if failureDetectionSet1-r17 and failureDetectionSet2-r17 are not included for the serving cell". Scheme 1-3 In scheme 1-3, for a service cell that is not configured with more than two beam failure detection reference signal (BFD-RS) groups, the terminal device is allowed to perform measurement relaxation of beam failure detection (BFD) when the low mobility criteria of beam failure detection (BFD) are met. For example, when the criteria for low mobility are met, the terminal device is allowed to perform BFD relaxation on a serving cell that is not configured with 2 BFD-RS sets. In a specific example, TS 38.300 may be modified, for example, as shown in Table 9. Table 9 Embodiments of the second aspect An embodiment of the second aspect of the present application provides a method for measuring relaxation, which is applied to a terminal device, for example, the terminal device 102 in FIG. 1 . Fig. 3 is a schematic diagram of a method for measuring relaxation according to an embodiment of the second aspect. As shown in Fig. 3, the method for measuring relaxation includes: Operation 301: For a serving cell configured with more than two beam failure detection reference signal (BFD-RS) groups, the terminal device performs beam failure detection (BFD) measurement relaxation. In the present application, based on operation 301, the terminal device may perform at least one of the following operations 302 or 303. Operation 302: For a service cell configured with more than two beam failure detection reference signal (BFD-RS) groups, the terminal device does not send measurement relaxation status information of beam failure detection (BFD) to the network device; or, for a service cell not configured with more than two beam failure detection reference signal (BFD-RS) groups, the terminal device sends measurement relaxation status information of beam failure detection (BFD) to the network device. For example, for a serving cell configured with two BFD-RS groups, the BFD measurement relaxation state is not reported; or only for a serving cell not configured with two BFD-RS groups, the BFD measurement relaxation state is reported. When operation 302 is performed, the overhead of the terminal device can be saved. In operation 302, the terminal device does not send measurement relaxation state information of beam failure detection (BFD) to the network device, including at least one of the following operations: Not triggering reporting of the measurement relaxation state information through the terminal device auxiliary information process; In the triggered terminal device auxiliary information process, the terminal device auxiliary information does not include the measurement relaxation state information; In the triggered terminal device auxiliary information process, the value of the bit corresponding to the serving cell in the terminal device auxiliary information is set to a first value, and the first value is 0, for example. Operation 303: For a serving cell configured with more than two beam failure detection reference signal (BFD-RS) groups, the terminal device sends measurement relaxation state information of beam failure detection (BFD) to the network device. For example, for a serving cell configured with two BFD-RS groups, the BFD measurement relaxation state is reported. When operation 303 is performed, the network device can be aware of the BFD measurement relaxation situation of the terminal device. In at least one embodiment, operation 302 may be implemented by at least one of the following implementation A and implementation B. Implementation A In at least one embodiment of implementation A, the terminal device does not send measurement relaxation status information of beam failure detection (BFD) to the network device, including: the terminal device is not configured to send measurement relaxation status information of beam failure detection (BFD) to the network device. For example, for a service cell configured with two BFD-RS groups, the terminal device is configured by the network device not to send the BFD measurement relaxation status to the network device. Alternatively, in at least one embodiment, for a service cell that is not configured with more than two beam failure detection reference signal (BFD-RS) groups, the terminal device sends measurement relaxation status information of beam failure detection (BFD) to the network device, including: the terminal device is configured to send measurement relaxation status information of beam failure detection (BFD) to the network device. For example, only for a service cell that is not configured with two BFD-RS groups, the terminal device is configured by the network device to send the BFD measurement relaxation status to the network device. In at least one embodiment, TS 38.300 may be modified, or the existence condition or domain description of the third parameter related to the beam failure detection relaxation reporting configuration (the third parameter is, for example, bfd-RelaxationReportingConfig) may be modified to implement implementation A. Wherein, when the beam failure detection reference signal (BFD-RS) group is reconfigured, the terminal device stops a running timer associated with the serving cell, the timer being, for example, T346j or T346k. Specifically, for modifying TS 38.300, the corresponding standards may be as shown in Table 10. Table 10 Or, modify the above content: "If configured to do so for the serving cell without mTRP, the UE shall trigger reporting of its RLM and / or BFD relaxation status through UE assistance information if the UE changes its respective RLM and / or BFD relaxation status while meeting the UE minimum requirements specified in TS 38.133

[0013] .” Modify the existence condition of bfd-RelaxationReportingConfig in TS38.331, and the corresponding standard can be shown in Table 11. Table 11 Or replace "failureDetectionSet1-r17 and failureDetectionSet2-r17 are included" with: "2 BFD-RS set are configured"; Or change the Explanation part to "The field is optionally present,Need R if failureDetectionSet1-r17 and failureDetectionSet2-r17 are not configured; otherwise it is absent,Need R.". Modify the domain description of bfd-RelaxationReportingConfig, and the corresponding standard can be shown in Table 12. Table 12 Or change the above description to "The network only includes this field if failureDetectionSet1-r17 and failureDetectionSet2-r17 are not included.". In at least another embodiment, the terminal device does not send measurement relaxation status information of beam failure detection (BFD) to the network device, including: the terminal device believes that the terminal device itself is not configured to send measurement relaxation status information of beam failure detection (BFD) to the network device. For example, for a service cell configured with two BFD-RS groups, the terminal device believes that the terminal device itself is not configured by the network device to send the BFD measurement relaxation status to the network device. Alternatively, in at least another embodiment, the terminal device sends measurement relaxation status information of beam failure detection (BFD) to the network device, including: the terminal device believes that the terminal device itself is configured to send measurement relaxation status information of beam failure detection (BFD) to the network device. For example, for a service cell that is not configured with two BFD-RS groups, the terminal device believes that the terminal device itself is configured by the network device to send the BFD measurement relaxation state to the network device. In this at least another embodiment, implementation A may be implemented by modifying 5.3.5.9 of TS 38.331, for example, as shown in Table 13. Table 13 Implementation method B. In at least one embodiment of implementation B, if the terminal device is configured to send measurement relaxation status information of beam failure detection (BFD) to the network device, and if the service cell is not configured with more than two beam failure detection reference signal (BFD-RS) groups, when the measurement relaxation status of the beam failure detection (BFD) of the terminal device on the service cell is changed and the minimum requirements of the terminal device are met, the terminal device sends measurement relaxation status information to the network device. In implementation mode B, the terminal device sends the measurement relaxation state information via terminal device auxiliary information. For example, if the terminal device is configured to send measurement relaxation state information of beam failure detection (BFD) to the network device, and if the serving cell is not configured with 2 BFD-RS groups, if the terminal device changes its BFD relaxation state while meeting the minimum requirements of the terminal device, the terminal device will trigger its BFD relaxation state through reporting of terminal device auxiliary information. In implementation B, the relaxation state of the terminal device is changed, for example, the terminal device changes from a non-relaxed state to a relaxed state, or the terminal device changes from a relaxed state to a non-relaxed state. The minimum requirements of the terminal device, for example, refer to the minimum requirements for terminal device measurement. In at least one embodiment, implementation mode B may be implemented by modifying the process description (5.7.4) of TS 38.331, for example, the corresponding standard is shown in Table 14. Table 14 In implementation B, the initiation of the terminal device auxiliary information process can be modified as follows: when the measurement relaxation state of the beam failure detection (BFD) in the radio link control connection (RRC_CONNECTED) state changes, if the terminal device is able to perform the measurement relaxation of the beam failure detection (BFD) in the radio link control connection (for example, RRC_CONNECTED) state, then the terminal device initiates the terminal device auxiliary information process, thereby sending measurement relaxation state information to the network device to indicate the measurement relaxation state of the service cell that is not configured with more than two (for example, two) beam failure detection reference signals (BFD-RS) groups. Next, operation 303 will be described. In operation 303, for a serving cell configured with more than two beam failure detection reference signal (BFD-RS) groups, the terminal device sends measurement relaxation state information of beam failure detection (BFD) to a network device. In operation 303, the terminal device may send the measurement relaxation state information for the service cell configured with more than two beam failure detection reference signal (BFD-RS) groups and the measurement relaxation state information for the service cell not configured with more than two beam failure detection reference signal (BFD-RS) groups to the network device.
