Description

[Technical Field]

[0001] FIELD OF THE INVENTION Embodiments of the present invention relate to the field of communications technology. [Background technology]

[0002] The terminal device can evaluate the downlink radio link quality of the serving cell based on the reference signal to detect beam failure, which applies to a PCell (primary cell) in an SA (Standalone Network), NR-DC (New Radio Dual Connectivity), or NE-DC (New Radio-Evolved Universal Terrestrial Radio Access Dual Connectivity) operation mode, a PSCell (primary secondary cell) in an NR-DC or EN-DC (Evolved Universal Terrestrial Radio Access-New Radio Dual Connectivity) operation mode, and a SCell (secondary cell) in an SA, NR-DC, NE-DC, or EN-DC operation mode.

[0003] SSB (Synchronization Signal Block)-based beam failure detection is based on the SSB associated with the initial DL BWP (Downlink Bandwidth Portion) and is configurable only 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 based only on the CSI-RS (Synchronization Signal Block / Channel State Information Reference Signal). The terminal is not required to perform beam failure detection for other than the active DL BWP.

[0004] Beam failure is detected by counting the number of beam failure instance indications from lower layers to a MAC (medium access control) entity.

[0005] In multi-TRP (Transmission / Receive Point) operation, the serving cell can schedule a terminal device (e.g., UE) from two TRPs to provide better coverage, reliability, and / or data rates for PDSCH (Physical Downlink Shared Channel), PDCCH (Physical Downlink Control Channel), PUSCH (Physical Uplink Shared Channel), and PUCCH (Physical Uplink Control Channel).

[0006] In beam failure detection in multi-TRP operation, a network device (e.g., a gNB) configures two or more sets of beam failure detection reference signals for a terminal device (e.g., a UE), with each TRP corresponding to one set.

[0007] If the beam failure instance indication associated with a set of beam failure detection reference signals from the physical layer reaches a configured threshold before the configured timer times out, the UE declares beam failure for the corresponding TRP.

[0008] The above description of the background art is merely for the purpose of explaining the configuration of the present invention more clearly and completely, and is provided for the understanding of those skilled in the art. These configurations described in the background art of the present invention should not be construed as being well known to those skilled in the art. Summary of the Invention [Problem to be solved by the invention]

[0009] Rel-17 introduces measurement relaxation for beam fault detection (BFD) to ensure energy saving of terminal equipment, and also introduces multi-TRP beam fault detection.

[0010] According to the findings of the inventors of the present invention, when multiple TRPs are configured for one serving cell, at least the following problems exist.

[0011] 1. The current BFD measurement mitigation status is reported by the serving cell and indicates 1 if BFD measurement mitigation is performed, and 0 if not. In the case of multi-TRP, the current mechanism cannot identify the reported content. Therefore, this leads to different understanding between the network device and the terminal device, which may cause the network device to behave improperly regarding the terminal device's mobility, resulting in service interruption.

[0012] 2. BFD measurement mitigation is performed based on cell-level measurement evaluation. However, if one TRP among multiple TRPs has good quality and the other TRPs have poor quality, the terminal device may perform mitigation on the BFD measurement of the poor-quality TRP, which may result in inappropriate behavior of the network device in response to the terminal device's mobility, resulting in service interruptions.

[0013] In view of at least one of the above problems, embodiments of the present invention provide a method, an apparatus, and a communication system for measurement mitigation that can avoid inappropriate operation of a network device with respect to a terminal device and avoid service interruption. [Means for solving the problem]

[0014] In one aspect of an embodiment of the present invention, there is provided an apparatus for measurement mitigation that is applied to a terminal device, the apparatus including a first application unit that prevents the terminal device from performing beam failure detection (BFD) measurement mitigation for a serving cell for which two or more beam failure detection reference signal (BFD-RS) sets are configured, or that causes the terminal device to perform beam failure detection (BFD) measurement mitigation for a serving cell for which two or more beam failure detection reference signal (BFD-RS) sets are not configured.

[0015] Another aspect of an embodiment of the present invention provides an apparatus for measurement mitigation, which is applied to a terminal device, and includes a second application unit, which causes the terminal device to perform beam failure detection (BFD) measurement mitigation for a serving cell for which two or more beam failure detection reference signal (BFD-RS) sets are configured.

[0016] Another aspect of an embodiment of the present invention provides an apparatus for measurement mitigation that is applied to a terminal device, the apparatus including a third application unit, wherein the third application unit configures the terminal device to set a value of the beam failure detection (BFD) measurement mitigation state corresponding to the serving cell to a second value when a serving cell for which two or more beam failure detection reference signal (BFD-RS) sets are not configured is performing beam failure detection (BFD) measurement mitigation, or configures the terminal device to set a value of the beam failure detection (BFD) mitigation state corresponding to the serving cell to a first value when two or more beam failure detection reference signal (BFD-RS) sets are configured for the serving cell.

[0017] Another aspect of an embodiment of the present invention provides an apparatus for measurement mitigation, which is applied to a network device, and includes a first component, wherein the first component configures two or more beam failure detection reference signal (BFD-RS) sets for a serving cell and configures the terminal device to perform beam failure detection (BFD) measurement mitigation.

[0027] 1 is a schematic diagram of an example of a communication system according to an embodiment of the present invention. As shown in FIG. 1, the communication system may include a network device 101 and a terminal device 102.

[0028] In an embodiment of the present invention, the term "network device" refers to a device in a communication system that allows a terminal device to access the communication system and provides a service to the terminal device, for example, the network device may include, but is not limited to, an access backhaul integration node (IAB-node), a relay, a base station (BS), an access point (AP), a transmission reception point (TRP), a broadcast transmitter, a mobility management entity (MME), a gateway, a server, a radio network controller (RNC), a base station controller (BSC), etc.

[0029] Here, the base station may include, but is not limited to, a Node B (NodeB or NB), an evolved Node B (eNodeB or eNB), a 5G base station (gNB), etc., as well as a remote radio head (RRH), a remote radio unit (RRU), a relay, or a low-power node (e.g., femto, pico, etc.). Also, the term "base station" may include some or all of these functions, and each base station may provide communication coverage for a particular geographic area. The term "cell" may refer to a base station and / or its coverage area, depending on the context in which the term is used.

[0030] In the embodiments of the present invention, the term "User Equipment" (UE) or "Terminal Equipment" (TE) refers to a device that accesses a communication network and receives network services via, for example, a network device. The terminal device may be fixed or mobile, and may also be referred to as a mobile station (MS), a terminal, a subscriber station (SS), an access terminal (AT), a mobile termination (MT), a station, etc.

[0034] In an embodiment of the present invention, the higher layer signaling may be, for example, Radio Resource Control (RRC) signaling, for example, referred to as an RRC message, including, for example, a Master Information Block (MIB), system information, and dedicated RRC messages, or referred to as an RRC information element (RRC IE). The higher layer signaling may be, for example, F1-C signaling, or referred to as an F1AP protocol. However, the present invention is not limited thereto.

[0035] The terminal can ensure energy conservation by relaxing the BFD measurements.

[0036] Once configured, the terminal determines whether it is in a low mobility state and / or whether the radio link quality of the serving cell is better than a threshold.

[0037] The terminal determines whether it is in a low mobility state as follows.

[0038] [Table 1] The terminal determines whether the radio link quality of the serving cell is better than a threshold as follows.

[0039] [Table 2] The criteria for low mobility and good serving cell quality are provided by dedicated signaling. The terminal is only allowed to perform BFD mitigation if the criteria for low mobility and / or good serving cell quality measurement mitigation are met.

[0040] RLM and BFD mitigation may be activated / deactivated respectively, and BFD may be activated / deactivated per serving cell.

[0041] If configured to do so, when the terminal changes the BFD mitigation state and the minimum requirements of the terminal are met, the terminal triggers reporting of the BFD mitigation state via UE assistance information.

[0042] The following IEs are used to configure the terminal to perform BFD mitigation state reporting:

[0043] [Table 3] TIFF2025525993000005.tif240170TIFF2025525993000006.tif241170TIFF2025525993000007.tif242170TIFF2025525993000008.tif243170

[0044] [Table 4] Based on the above configuration, the terminal determines whether to report the BFD relaxation state in the following process:

[0045] [Table 5] TIFF2025525993000011.tif243170TIFF2025525993000012.tif237170TIFF2025525993000013.tif244170TIFF2025525993000014.tif244170TIFF2025525993000015.tif86170When configured as above and the BFD measurement mitigation state in RRC_CONNECTED is changed, a UE that is capable of mitigating BFD measurements of a cell set in RRC_CONNECTED state initiates the following process to provide an indication of its own BFD measurement mitigation state.

[0046] [Table 6] The following timers are used to control reporting:

[0047] [Table 7] The report content is set as follows:

[0048] [Table 8] The specific message is as follows:

[0049] [Table 9] TIFF2025525993000020.tif240170TIFF2025525993000021.tif241170TIFF2025525993000022.tif241170TIFF20255259930 00023.tif240170TIFF2025525993000024.tif240170TIFF2025525993000025.tif240170TIFF2025525993000026.tif245170

[0050] [Table 10] The transmission of the UE assistance information message is as follows:

[0051] [Table 11] TIFF2025525993000029.tif30170Each embodiment of the present invention is based on the following scenario.

[0052] Two or more beam failure detection reference signal (BFD-RS) sets, for example, two BFD-RS sets, are configured for the serving cell of the terminal device. Alternatively, carrier aggregation is configured for the terminal device. Beam failure detection is configured for some serving cells. Two or more BFD-RS sets are configured for some of these serving cells, i.e., beam failure detection is performed for the BFD-RS sets. Two or more BFD-RS sets are not configured for other cells, i.e., beam failure detection is performed for the serving cell.

[0053] For example, configuring two or more BFD-RS sets for a cell includes configuring failureDetectionSet1-r17 and failureDetectionSet2-r17 for one serving cell.

[0054] For example, at least two serving cells are configured for carrier aggregation for a terminal device, where beam failure detection is configured for cell 1 (special cell or secondary cell) and two or more BFD-RS sets are configured, beam failure detection is configured for cell 2 (secondary cell) and two or more BFD-RS sets are not configured, and cell 3 may be configured for the terminal device.

[0055] For example, the terminal device performs BFD-RS set beam failure detection for each BFD-RS set of cell 1, and performs serving cell beam failure detection for cell 2.

[0056] Example 1 A first embodiment of the present invention provides a method for measurement relaxation, which is applied to a terminal device, for example, the terminal device 102 in FIG.

[0057] 2 is a schematic diagram of an example of a method for measurement relaxation according to Example 1. As shown in FIG. 2, the method for measurement relaxation includes the following steps.

[0058] Step 201: For a serving cell for which two or more beam failure detection reference signal (BFD-RS) sets are configured, the terminal device does not perform beam failure detection (BFD) measurement mitigation, or for a serving cell for which two or more beam failure detection reference signal (BFD-RS) sets are not configured, the terminal device performs beam failure detection (BFD) measurement mitigation.

[0059] For example, in step 201, BFD mitigation is not performed for serving cells in which two BFD-RS sets are configured, or BFD mitigation is performed only for serving cells in which two BFD-RS sets are not configured.

[0060] According to Example 1, in the case of multi-TRP, since the network device and the terminal device have the same understanding of BFD measurement relaxation, it is possible to avoid inappropriate operation of the network device toward the terminal device and to avoid service interruption.

[0061] In the present invention, step 201 may be realized by at least one of the following schemes 1-1, 1-2, and 1-3.

[0062] Scheme 1-1: In Scheme 1-1, the terminal device not performing beam fault detection (BFD) measurement mitigation includes the beam fault detection (BFD) measurement mitigation being disabled, where disabled may mean not permitted, deactivated, etc.

[0063] In Scheme 1-1, the terminal device performing beam fault detection (BFD) measurement mitigation includes enabling the beam fault detection (BFD) measurement mitigation, where enabled may mean permitted, activated, enabled, etc.

[0064] In at least one embodiment of Scheme 1-1, for a serving cell in which two BFD-RS sets are configured, BFD measurement mitigation is disabled, and for a serving cell in which two BFD-RS sets are not configured, BFD measurement mitigation is enabled.

[0065] For example, the existence condition or field description of the first parameter related to the low mobility criterion and / or the second parameter related to the good cell quality criterion may be changed, where the first parameter may be lowMobilityEvaluationConnected and the second parameter may be goodServingCellEvaluationBFD, and the second parameter may be a second parameter for a special cell and / or a secondary cell.

[0066] Here, changing the existence condition or field description of the first parameter (lowMobilityEvaluationConnected) related to the low mobility criterion includes disabling beam failure detection (BFD) measurement mitigation or enabling beam failure detection (BFD) measurement mitigation when the serving cell is a special cell and a first serving cell exists in the cell set in which the serving cell is located, for which two or more beam failure detection reference signal (BFD-RS) sets are not configured.

[0067] Specifically, the corresponding criteria for changing the existence condition of an IE (Information Element) are as follows:

[0068] (1) The criteria for lowMobilityEvaluationConnected are shown in Table 1.

[0069] Table 1

[0070] [Table 12] TIFF2025525993000031.tif241170TIFF2025525993000032.tif241170TIFF2025525993000033.tif241170TIFF2025525993000034.tif241170TIFF2025525993000035.tif63170Alternatively, replace "failureDetectionSet1-r17 and failureDetectionSet2-r17 are included" above with "2 BFD RS set are configured".

[0071] Alternatively, 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." (2) Regarding goodServingCellEvaluationBFD, the criteria are shown in Table 2.

[0072] Table 2

[0073] [Table 13] TIFF2025525993000037.tif241170TIFF2025525993000038.tif241170TIFF2025525993000039.tif240170TIFF2025525993000040.tif240170TIFF2025525993000041.tif62170Alternatively, replace the above "failureDetectionSet1-r17 and failureDetectionSet2-r17 are included" with "2 BFD RS set are configured".

[0074] Alternatively, 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."

[0075] Alternatively, modify the IE field description and the corresponding standard becomes:

[0076] (1) The standards for lowMobilityEvaluationConnected are shown in Table 3.

[0077] Table 3

[0078] [Table 14] TIFF2025525993000043.tif246170TIFF2025525993000044.tif246170TIFF2025525993000045.tif245170TIFF2025525993000046.tif247170TIFF2025525993000047.tif242170TIFF2025525993000048.tif59170Alternatively, replace the condition with "if NR PSCell without mTRP".

[0079] (2) Regarding goodServingCellEvaluationBFD, the criteria are shown in Table 4.

[0080] Table 4

[0081] [Table 15] TIFF2025525993000050.tif246170TIFF2025525993000051.tif246170TIFF2025525993000052.tif246170TIFF2025525993000053.tif246170TIFF2025525993000054.tif241170TIFF2025525993000055.tif60170Or replace with "this SCell / SpCell without mTRP".

[0082] Scheme 1-1 may also be realized by describing it in the process description of TS38.300 or TS38.331, for example.

[0083] Specifically, this is explained in TS38.300, and the corresponding standards are shown in Table 5.

[0084] Table 5

[0085] [Table 16] TIFF2025525993000057.tif243170TIFF2025525993000058.tif75170Alternatively, you can add the following statement, replacing "RLM and BFD relaxation may be enabled if there is no serving cell with mTRP." with "RLM and BFD relaxation will be disabled if any serving cell with mTRP is configured."

[0086] This is explained in the process description of TS38.331, and the corresponding criteria are shown in Table 6.

[0087] Table 6

[0088] [Table 17] TIFF2025525993000060.tif119170 Or, for each of the above parameters, add "and if failureDetectionSet1-r17 and failureDetectionSet2-r17 are not configured for this SpCell" after "if the SpCellConfig contains the ...".

[0089] Scheme 1-2: In Scheme 1-2, not performing beam failure detection (BFD) measurement mitigation includes not evaluating whether the beam failure detection (BFD) measurement mitigation criteria in the serving cell are met.

[0090] In Scheme 1-2, performing beam failure detection (BFD) measurement mitigation includes evaluating whether beam failure detection (BFD) measurement mitigation criteria at the serving cell are met.

[0091] For example, the mitigation measurement criteria for a serving cell in which two BFD-RS sets are configured are not evaluated to determine whether they are met, or the mitigation measurement criteria for a serving cell in which two BFD-RS sets are not configured are only evaluated to determine whether they are met.

[0092] In Schemes 1-2, whether the measurement relaxation criteria are met may include 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.

[0093] Here, whether the low mobility criterion is met includes evaluating whether the low mobility criterion is met when two or more (e.g., two) beam failure detection reference signal (BFD-RS) sets are not configured in the cell set in which the serving cell is located.

[0094] In at least one embodiment of Scheme 1-2, Scheme 1-2 may be implemented by modifying 5.7.13 of TS 38.331 or TS 38.300.

[0095] Specifically, this is explained in TS38.300, and the corresponding standards are shown in Table 7.

[0096] Table 7

[0097] [Table 18] This may be explained in the process description of TIFF2025525993000062.tif243170TIFF2025525993000063.tif45170TS38.331, and the corresponding criteria are shown in Table 8.

[0098] Table 8

[0099] [Table 19] Alternatively, replace it with "if failureDetectionSet1-r17 and failureDetectionSet2-r17 are not included for the serving cell".

[0100] Schemes 1-3: In schemes 1 to 3, for a serving cell for which two or more beam failure detection reference signal (BFD-RS) sets are not configured, if the low mobility criterion for beam failure detection (BFD) is met, the terminal device is allowed to perform beam failure detection (BFD) measurement mitigation.

[0101] For example, if a low mobility criterion is met, the terminal device is allowed to perform BFD mitigation in a serving cell in which two BFD-RS sets are not configured.

[0102] In a specific example, TS 38.300 may be amended, for example, as shown in Table 9.

[0103] Table 9

[0104] [Table 20] TIFF2025525993000066.tif243170TIFF2025525993000067.tif53170<Example 2> A second embodiment of the present invention provides a method for measurement relaxation, which is applied to a terminal device, for example, the terminal device 102 in FIG.

[0105] 3 is a schematic diagram of an example of a method for measurement relaxation according to Example 2. As shown in FIG. 3, the method for measurement relaxation includes the following steps.

[0106] Step 301: For a serving cell for which two or more beam failure detection reference signal (BFD-RS) sets are configured, the terminal device performs measurement mitigation of beam failure detection (BFD).

[0107] In the present invention, based on step 301, the terminal device may perform at least one of the following steps 302 or 303.

[0108] Step 302: For a serving cell for which two or more beam fault detection reference signal (BFD-RS) sets are configured, the terminal device does not send beam fault detection (BFD) measurement mitigation status information to the network device, or for a serving cell for which two or more beam fault detection reference signal (BFD-RS) sets are not configured, the terminal device sends beam fault detection (BFD) measurement mitigation status information to the network device.

[0109] For example, the BFD measurement mitigation status may not be reported for serving cells in which two BFD-RS sets are configured, or the BFD measurement mitigation status may be reported only for serving cells in which two BFD-RS sets are not configured.

[0110] By performing step 302, overhead on the terminal device can be saved.

[0111] In step 302, not sending beam fault detection (BFD) measurement mitigation status information to the network device is not triggering reporting of measurement mitigation status information via the terminal device assistance information process; Not including the measurement relaxation state information in the terminal device assistance information process triggered, or The method includes at least one of setting a value of a bit corresponding to the serving cell in the terminal device auxiliary information to a first value in the triggered terminal device auxiliary information process, where the first value is, for example, 0.

[0112] Step 303: For a serving cell for which two or more beam failure detection reference signal (BFD-RS) sets are configured, the terminal device sends beam failure detection (BFD) measurement mitigation status information to the network device.

[0113] For example, report the BFD measurement mitigation state for a serving cell with two BFD-RS sets configured.

[0114] By performing step 303, the network device can grasp the BFD measurement mitigation status of the terminal device.

[0115] In at least one embodiment, step 302 may be implemented by at least one of the following embodiments A and B.

[0116] Embodiment A: In at least one embodiment of embodiment A, the terminal device not transmitting beam fault detection (BFD) measurement mitigation status information to the network device includes the terminal device not being configured to transmit beam fault detection (BFD) measurement mitigation status information to the network device.

[0117] For example, for a serving cell in which two BFD-RS sets are configured, the terminal device is configured by the network device not to send a BFD measurement mitigation state to the network device.

[0118] Alternatively, in at least one embodiment, for a serving cell for which two or more beam failure detection reference signal (BFD-RS) sets are not configured, the terminal device transmitting beam failure detection (BFD) measurement mitigation state information to a network device includes the terminal device being configured to transmit beam failure detection (BFD) measurement mitigation state information to the network device.

[0119] For example, the terminal device is configured by the network device to send the BFD measurement mitigation state to the network device only for serving cells for which two BFD-RS sets are not configured.

[0120] In at least one embodiment, to implement embodiment A, TS 38.300 may be modified, or the existence condition or field description of a third parameter related to the relaxation reporting configuration for beam failure detection (the third parameter is, for example, bfd-RelaxationReportingConfig) may be modified. Here, when the beam failure detection reference signal (BFD-RS) set is reconfigured, the terminal device stops an active timer associated with the serving cell. The timer may be, for example, T346j or T346k.

[0121] Specifically, when amending TS 38.300, the corresponding criteria may be shown in Table 10.

[0122] Table 10

[0123] [Table 21] TIFF2025525993000069.tif243170TIFF2025525993000070.tif81170Alternatively, amend the above content to read, "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

[13] ."

[0124] In the amendment of TS38.331, the existence condition of bfd-RelaxationReportingConfig may be amended, and the corresponding criteria may be shown in Table 11.

[0125] Table 11

[0126] [Table 22] TIFF2025525993000072.tif241170TIFF2025525993000073.tif241170TIFF2025525993000074.tif241170TIFF2025525993000075.tif228170Alternatively, replace "failureDetectionSet1-r17 and failureDetectionSet2-r17 are included" above with "2 BFD-RS set are configured".

[0127] Alternatively, 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."

[0128] The field descriptions of bfd-RelaxationReportingConfig may be changed and the corresponding criteria shown in Table 12.

[0129] Table 12

[0130] [Table 23] TIFF2025525993000077.tif241170TIFF2025525993000078.tif241170TIFF2025525993000079.tif241170TIFF2025525993000080.tif241170TIFF2025525993000081.tif47170Alternatively, replace the above statement with "The network only includes this field if failureDetectionSet1-r17 and failureDetectionSet2-r17 are not included."

[0131] In at least one other embodiment, the terminal device not transmitting beam fault detection (BFD) measurement mitigation status information to the network device includes the terminal device assuming that the terminal device is not configured to transmit beam fault detection (BFD) measurement mitigation status information to the network device.

[0132] For example, for a serving cell in which two BFD-RS sets are configured, the terminal device considers that the terminal device itself is not configured by the network device to send BFD measurement mitigation status to the network device.

[0133] Alternatively, in at least one other embodiment, the terminal device transmitting beam fault detection (BFD) measurement mitigation status information to the network device includes the terminal device assuming that the terminal device is configured to transmit beam fault detection (BFD) measurement mitigation status information to the network device.

[0134] For example, for a serving cell in which two BFD-RS sets are not configured, the terminal device considers that the terminal device itself is configured by the network device to send a BFD measurement mitigation state to the network device.

[0135] In at least one other example, to implement embodiment A, 5.3.5.9 of TS 38.331 may be modified, for example, as shown in Table 13.

[0136] Table 13

[0137] [Table 24] TIFF2025525993000083.tif238170TIFF2025525993000084.tif243170TIFF2025525993000085.tif244170TIFF2025525993000086.tif240170TIFF2025525993000087.tif89170Embodiment B: In at least one embodiment of embodiment B, a terminal device is configured to transmit beam failure detection (BFD) measurement mitigation state information to a network device, and when two or more beam failure detection reference signal (BFD-RS) sets are not configured for a serving cell, the terminal device transmits the measurement mitigation state information to the network device when the beam failure detection (BFD) measurement mitigation state in the terminal device's serving cell is changed and the terminal device's minimum requirements are met.

[0138] In embodiment B, the terminal device transmits measurement relaxation state information via terminal device assistance information.

[0139] For example, if a terminal device is configured to send beam fault detection (BFD) measurement mitigation state information to a network device and is not configured with two BFD-RS sets for the serving cell, when the terminal device changes its BFD mitigation state and the minimum requirements for the terminal device are met, the terminal device triggers reporting of its BFD mitigation state via terminal device auxiliary information.

[0140] In embodiment B, a change in the mitigated state of a terminal device means, for example, that the terminal device is changed from a non-mitigated state to a mitigated state, or that the terminal device is changed from a mitigated state to a non-mitigated state.

[0141] The minimum requirements of the terminal device may for example mean the minimum requirements for the measurement of the terminal device.

[0142] In at least one example, to implement embodiment B, the process description (5.7.4) of TS 38.331 may be modified, for example, with corresponding criteria as shown in Table 14.

[0143] Table 14

[0144] [Table 25] TIFF2025525993000089.tif148170 In embodiment B, the initiation of the terminal device assistance information process may be modified such that when the beam failure detection (BFD) measurement mitigation state is changed in the radio link control connected (RRC_CONNECTED) state, when the terminal device is capable of performing beam failure detection (BFD) measurement mitigation in the radio link control connected (RRC_CONNECTED) state, the terminal device initiates the terminal device assistance information process and transmits measurement mitigation state information to the network device to indicate the measurement mitigation state of serving cells for which two or more (e.g., two) beam failure detection reference signal (BFD-RS) sets are not configured.

[0145] Step 303 will be described below.

[0146] In step 303, for a serving cell for which two or more beam failure detection reference signal (BFD-RS) sets are configured, the terminal device transmits beam failure detection (BFD) measurement mitigation status information to the network device.

[0147] In step 303, the terminal device may transmit measurement mitigation status information of a serving cell for which two or more beam failure detection reference signal (BFD-RS) sets are configured and measurement mitigation status information of a serving cell for which two or more beam failure detection reference signal (BFD-RS) sets are not configured together to the network device. For example, the terminal device may transmit the measurement mitigation status information of a serving cell for which two or more beam failure detection reference signal (BFD-RS) sets are configured and measurement mitigation status information of a serving cell for which two or more beam failure detection reference signal (BFD-RS) sets are not configured to the network device in the same bit stream.

[0148] Alternatively, in step 303, the terminal device may separately transmit the measurement mitigation status information of the serving cell for which two or more beam failure detection reference signal (BFD-RS) sets are configured and the measurement mitigation status information of the serving cell for which two or more beam failure detection reference signal (BFD-RS) sets are not configured to the network device. For example, the terminal device may place the measurement mitigation status information of the serving cell for which two or more beam failure detection reference signal (BFD-RS) sets are configured and the measurement mitigation status information of the serving cell for which two or more beam failure detection reference signal (BFD-RS) sets are not configured to the network device in different bit streams (e.g., two bit streams).

[0149] In at least one embodiment of step 303, when measurement mitigation state information of a serving cell for which two or more beam failure detection reference signal (BFD-RS) sets are configured and measurement mitigation state information of a serving cell for which two or more beam failure detection reference signal (BFD-RS) sets are not configured are transmitted together to a network device, the measurement mitigation state includes the measurement mitigation state of one beam failure detection reference signal (BFD-RS) set.

[0150] Here, one beam fault detection reference signal (BFD-RS) set is configured by a network device, or one beam fault detection reference signal (BFD-RS) set means the first beam fault detection reference signal (BFD-RS) set, for example, the BFD-RS set that appears first when a network device configures a BFD-RS set, or one beam fault detection reference signal (BFD-RS) set is a beam fault detection reference signal (BFD-RS) set corresponding to a transmission / reception point (TRP) performing non-terminal device-specific or terminal device-specific transmission.

[0151] In at least one other embodiment of step 303, when the terminal device transmits measurement mitigation status information of a serving cell for which two or more beam failure detection reference signal (BFD-RS) sets are configured and measurement mitigation status information of a serving cell for which two or more beam failure detection reference signal (BFD-RS) sets are not configured to the network device, together or separately, the measurement mitigation status includes whether the measurement mitigation status of the two or more beam failure detection reference signal (BFD-RS) sets match.

[0152] Here, if the measurement relaxation states of two or more beam fault detection reference signal (BFD-RS) sets do not match, a first value is indicated, the first value being, for example, 0; or if the measurement relaxation states of two or more beam fault detection reference signal (BFD-RS) sets match, a second value is indicated, the second value being, for example, 1.

[0153] In at least one other embodiment of step 303, when a terminal device transmits measurement mitigation state information of a serving cell for which two or more beam failure detection reference signal (BFD-RS) sets are configured and measurement mitigation state information of a serving cell for which two or more beam failure detection reference signal (BFD-RS) sets are not configured to the network device, together or separately, the measurement mitigation state includes the measurement mitigation state of two or more beam failure detection reference signal (BFD-RS) sets.

[0154] Here, if two or more beam fault detection reference signal (BFD-RS) sets are all performing beam fault detection (BFD) measurement mitigation, the second value indicates a second value, for example, 1; otherwise, the first value indicates a first value, for example, 0; or, if two or more beam fault detection reference signal (BFD-RS) sets are not performing beam fault detection (BFD) measurement mitigation, the first value indicates a first value, for example, 0; otherwise, the second value indicates a second value, for example, 1.

[0155] In at least one embodiment of step 303, when a terminal device transmits measurement mitigation status information of a serving cell for which two or more beam failure detection reference signal (BFD-RS) sets are configured and measurement mitigation status information of a serving cell for which two or more beam failure detection reference signal (BFD-RS) sets are not configured to a network device, either together or separately, the measurement mitigation status information has the same number of first information bits as the number of two or more beam failure detection reference signal (BFD-RS) sets, and each first information bit indicates whether the corresponding beam failure detection reference signal (BFD-RS) set performs beam failure detection (BFD) measurement mitigation.

[0156] FIG. 4 is a schematic diagram of another example of a method for measurement relaxation according to the second embodiment, where the method for measurement relaxation is applied to a terminal device.

[0157] As shown in FIG. 4, the method for measuring relaxation includes the following steps.

[0158] Step 401: If a serving cell for which two or more beam failure detection reference signal (BFD-RS) sets are not configured is performing beam failure detection (BFD) measurement mitigation, the terminal device sets the value of the beam failure detection (BFD) measurement mitigation state corresponding to the serving cell to a second value, or if two or more beam failure detection reference signal (BFD-RS) sets are configured for the serving cell, the terminal device sets the value of the beam failure detection (BFD) mitigation state corresponding to the serving cell to a first value.

[0159] In at least one embodiment of step 401, if a serving cell for which two or more beam failure detection reference signal (BFD-RS) sets are not configured is performing beam failure detection (BFD) measurement mitigation, the terminal device sets the value of the beam failure detection (BFD) measurement mitigation state corresponding to the serving cell to a second value, e.g., 1; otherwise, the terminal device sets the value of the beam failure detection (BFD) measurement mitigation state corresponding to the serving cell to a first value, e.g., 0.

[0160] Here, other cases include two or more beam failure detection reference signal (BFD-RS) sets being configured for the serving cell.

[0161] Example 3 A third embodiment of the present invention provides a method for measurement relaxation, which is applied to a network terminal device, such as the network device 101 in FIG.

[0162] 5 is a schematic diagram of an example of a method for measurement relaxation according to Example 3. As shown in FIG. 5, the method for measurement relaxation includes the following steps.

[0163] Step 501: Configure two or more beam failure detection reference signal (BFD-RS) sets for a serving cell.

[0164] Step 502: Configure the terminal device to perform beam fault detection (BFD) measurement mitigation.

[0165] As shown in FIG. 5, the method further includes step 503 or step 504.

[0166] Step 503: For a serving cell in which two or more beam failure detection reference signal (BFD-RS) sets are configured, configure the terminal device not to send beam failure detection (BFD) measurement mitigation status information to the network device, or for a serving cell in which two or more beam failure detection reference signal (BFD-RS) sets are not configured, configure the terminal device to send beam failure detection (BFD) measurement mitigation status information to the network device.

[0167] Here, step 503 may be realized by changing the existence condition or field description of the third parameter (bfd-RelaxationReportingConfig) relating to relaxation reporting configuration for beam obstruction detection.

[0168] Step 504: For a serving cell for which two or more beam failure detection reference signal (BFD-RS) sets are configured, configure the terminal device to send beam failure detection (BFD) measurement mitigation status information to the network device.

[0169] In step 504, the network device receives measurement mitigation status information of a serving cell for which two or more beam failure detection reference signal (BFD-RS) sets are configured, and measurement mitigation status information of a serving cell for which two or more beam failure detection reference signal (BFD-RS) sets are not configured, together or separately.

[0170] In at least one embodiment of step 504, the measurement relaxation state includes a measurement relaxation state for one beam fault detection reference signal (BFD-RS) set.

[0171] Here, one beam fault detection reference signal (BFD-RS) set is configured by a network device, or one beam fault detection reference signal (BFD-RS) set means the first beam fault detection reference signal (BFD-RS) set, or one beam fault detection reference signal (BFD-RS) set is a beam fault detection reference signal (BFD-RS) set corresponding to a transmission / reception point (TRP) performing non-terminal device-specific or terminal device-specific transmission.

[0172] In at least one other embodiment of step 504, the measurement relaxation state includes whether the measurement relaxation states of two or more beam fault detection reference signal (BFD-RS) sets match.

[0173] Here, if the measurement mitigation states of two or more beam fault detection reference signal (BFD-RS) sets do not match, a first value (0) is indicated, or if the measurement mitigation states of two or more beam fault detection reference signal (BFD-RS) sets match, a second value (1) is indicated.

[0174] In at least one other embodiment of step 504, the measurement relaxation states include measurement relaxation states for two or more beam fault detection reference signal (BFD-RS) sets.

[0175] Here, if two or more beam fault detection reference signal (BFD-RS) sets are both performing beam fault detection (BFD) measurement mitigation, it indicates the second value (1), and if not, it indicates the first value (0), or if two or more beam fault detection reference signal (BFD-RS) sets are not performing beam fault detection (BFD) measurement mitigation, it indicates the first value (0), and if not, it indicates the second value (1).

[0176] In at least one other embodiment of step 504, the measurement mitigation status information has a number of first information bits equal to the number of two or more beam fault detection reference signal (BFD-RS) sets, and each first information bit indicates whether the corresponding beam fault detection reference signal (BFD-RS) set performs beam fault detection (BFD) measurement mitigation.
