Description

Technical Field

[0001] Embodiments of the present invention relate to the field of communication technologies.

Background Art

[0002] A terminal device can evaluate the downlink radio link quality of a serving cell based on a reference signal and detect a beam failure. This 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 an SCell (Secondary Cell) in an SA, NR-DC, NE-DC or EN-DC operation mode.

[0003] Beam failure detection based on an SSB (Synchronization Signal Block) is based on the SSB related to the initial DL BWP (Downlink Bandwidth Part), and can be configured only for the initial DL BWPs and the DL BWPs including the SSB related to the initial DL BWP. For other DL BWPs, beam failure detection is performed based only on CSI-RS (Synchronization Signal Block / Channel State Information Reference Signal). It is not necessary for the terminal to perform beam failure detection outside the active DL BWP.

[0004] A beam failure is detected by calculating the number of beam failure instance indications from the lower layer to the MAC (Media Access Control) entity.

[0005] In multi-TRP (transmit / receive point) operation, a serving cell can schedule terminal devices (e.g., UEs) 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 fault detection with multi-TRP operation, the network device (e.g., gNB) configures two or more beam fault detection reference signals for the terminal device (e.g., UE), with each TRP corresponding to one of these signals.

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

[0008] Furthermore, the above explanation of the background art is merely intended to provide a clearer and more complete explanation of the present invention's structure and to facilitate understanding for those skilled in the art. These structures, as described in the background art section of the present invention, should not be construed as being well-known to those skilled in the art. [Overview of the project] [Problems that the invention aims to solve]

[0009] Rel-17 (Release 17) introduces measurement relaxation for BFD (Beam Fault Detection) to ensure energy savings in terminal equipment. Multi-TRP beam fault detection has also been introduced.

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

[0011] 1. The current BFD measurement relaxation status is reported by the serving cell, showing 1 if BFD measurement relaxation is being performed, and 0 otherwise. In the case of multi-TRP, the current mechanism cannot determine what has been reported. Therefore, this can lead to different understandings between network devices and terminal devices, potentially resulting in improper operation of network devices in relation to terminal device mobility and service interruptions.

[0012] 2. While BFD measurement relaxation is performed based on cell-level measurement evaluation, if one of several TRPs is of good quality while others are of poor quality, the terminal device may perform relaxation for the BFD measurement of the poor-quality TRP, which could lead to improper operation of the network device relative to the terminal device's mobility and potentially cause service interruptions.

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

[0014] In one embodiment of the present invention, there is a device for measurement relaxation applied to a terminal device, comprising a first application unit, the first application unit causing the terminal device not to perform measurement relaxation of beam fault detection (BFD) for serving cells configured with two or more beam fault detection reference signal (BFD-RS) sets, or causing the terminal device to perform measurement relaxation of beam fault detection (BFD) for serving cells not configured with two or more beam fault detection reference signal (BFD-RS) sets.

[0015] In another embodiment of the present invention, there is a device for measurement relaxation applied to a terminal device, comprising a second application unit, the second application unit causing the terminal device to perform measurement relaxation of beam fault detection (BFD) for a serving cell comprising two or more beam fault detection reference signal (BFD-RS) sets.

[0016] In another embodiment of the present invention, there is a device for measurement relaxation applied to a terminal device, comprising a third application unit, the third application unit causing the terminal device to set the value of the beam fault detection (BFD) relaxation state corresponding to a serving cell to a second value when a serving cell for which two or more beam fault detection reference signal (BFD-RS) sets are configured is performing beam fault detection (BFD) measurement relaxation, or causing the terminal device to set the value of the beam fault detection (BFD) relaxation state corresponding to a serving cell to a first value when two or more beam fault detection reference signal (BFD-RS) sets are configured for the serving cell.

[0017] Another embodiment of the present invention provides a device for measurement relaxation applied to a network device, comprising a first component, the first component comprising two or more beam fault detection reference signal (BFD-RS) sets for a serving cell, and the terminal device being configured to perform measurement relaxation of beam fault detection (BFD).

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

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

[0029] Here, base stations may include, but are not limited to, node B (NodeB or NB), evolutionary node B (eNodeB or eNB), and 5G base stations (gNB), as well as remote radio heads (RRH), remote radio units (RRU), relays, or low-power nodes (e.g., femto, pico). The term “base station” may also include some or all of their functions, and each base station may provide communication coverage to a specific geographic area.

[0035] The device can conserve energy by mitigating BFD measurements.

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

[0037] The device determines whether or not it is in a low-mobility state as follows:

[0038] [Table 1] The terminal determines whether the serving cell's wireless link quality is better than the threshold, as follows:

[0039] [Table 2] Criteria for low mobility and good serving cell quality are provided through dedicated signaling. A terminal is permitted to perform BFD mitigation only if the criteria for measurement relaxation of low mobility and / or good serving cell quality are met.

[0040] RLM and BFD mitigation may be activated or deactivated, respectively, and BFD may be activated or deactivated on a per-serving-cell basis.

[0041] If configured to run, when a terminal changes its BFD mitigation state and the terminal's minimum requirements are met, the terminal triggers a report of its BFD mitigation state via UE auxiliary information.

[0042] Use the following Internet Explorer to configure the terminal to perform BFD mitigation status reporting.

[0043] [Table 3] TIFF0007861909000004.tif240170TIFF0007861909000005.tif241170TIFF0007861909000006.tif242170TIFF0007861909000007.tif243170

[0044] [Table 4] Based on the above configuration, the terminal decides whether or not to report a BFD relaxation state in the following process.

[0045] [Table 5] TIFF0007861909000010.tif243170TIFF0007861909000011.tif237170TIFF0007861909000012.tif244170TIFF0007861909000013.tif244170TIFF0007861909000014.tif86170 If configured as described above, and the relaxation state of the BFD measurement in RRC_CONNECTED is changed, a UE capable of relaxing the BFD measurement of a cell set in the RRC_CONNECTED state will initiate the following process to provide instructions for its own relaxation state of the BFD measurement.

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

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

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

[0049] [Table 9] TIFF0007861909000019.tif240170TIFF0007861909000020.tif241170TIFF0007861909000021.tif241170TIFF00078619090 00022.tif240170TIFF0007861909000023.tif240170TIFF0007861909000024.tif240170TIFF0007861909000025.tif245170

[0050] [Table 10] The transmission of UE auxiliary information messages is as follows:

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

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

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

[0054] For example, a terminal device is configured with at least two serving cells for carrier aggregation. Here, cell 1 (special cell or secondary cell) is configured with beam fault detection and has two or more BFD-RS sets. Cell 2 (secondary cell) is configured with beam fault detection and does not have two or more BFD-RS sets. A cell 3 may also be configured in the terminal device.

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

[0056] <Example 1> Embodiment 1 of the present invention provides a method for measurement relaxation. The method is applied to a terminal device, for example, the terminal device 102 in Figure 1.

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

[0058] Step 201: For serving cells configured with two or more beam fault detection reference signal (BFD-RS) sets, the terminal device does not perform beam fault detection (BFD) measurement relaxation, or for serving cells not configured with two or more beam fault detection reference signal (BFD-RS) sets, the terminal device performs beam fault detection (BFD) measurement relaxation.

[0059] For example, in step 201, BFD relaxation may be not performed for serving cells that have two BFD-RS sets configured, or BFD relaxation may be performed only for serving cells that do not have two BFD-RS sets 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 with respect to the terminal device and to avoid service interruptions.

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

[0062] Scheme 1-1: In Scheme 1-1, the failure of a terminal device to perform beam fault detection (BFD) measurement relaxation includes the disabling of beam fault detection (BFD) measurement relaxation. Here, disabling may mean not being permitted, deactivating, or otherwise.

[0063] In Scheme 1-1, the terminal device performing beam fault detection (BFD) measurement mitigation includes enabling beam fault detection (BFD) measurement mitigation. Here, enabling may mean permitting, activating, or making available.

[0064] In at least one embodiment of Scheme 1-1, BFD measurement relaxation is disabled for serving cells that have two BFD-RS sets configured. For serving cells that do not have two BFD-RS sets configured, BFD measurement relaxation is enabled.

[0065] For example, the existence conditions or field descriptions for the first parameter relating to low mobility criteria and / or the second parameter relating to good cell quality criteria may be changed. Here, the first parameter may be lowMobilityEvaluationConnected, and the second parameter may be goodServingCellEvaluationBFD. The second parameter may also be a second parameter relating to special cells and / or secondary cells.

[0066] Here, changing the existence condition or field description of the first parameter (lowMobilityEvaluationConnected) for low mobility criteria includes disabling or enabling beam fault detection (BFD) measurement relaxation if the serving cell is a special cell and there is a first serving cell in the cell set to which the serving cell is located that does not have two or more beam fault detection reference signal (BFD-RS) sets configured.

[0067] Specifically, the corresponding criteria for changing the existence conditions of IE (information elements) are as follows:

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

[0069] Table 1

[0070] [Table 12] TIFF0007861909000030.tif241170TIFF0007861909000031.tif241170TIFF0007861909000032.tif241170TIFF0007861909000033.tif241170TIFF0007861909000034.tif63170 Alternatively, replace "failureDetectionSet1-r17 and failureDetectionSet2-r17 are included" with "2 BFD RS sets are configured".

[0071] Alternatively, change the Explanation section to "The field is optionally present. Need R if failureDetectionSet1-r17 and failureDetectionSet2-r17 are not configured; otherwise, it is absent. Need R." (2) The criteria for goodServingCellEvaluationBFD are shown in Table 2.

[0072] Table 2

[0073] [Table 13] TIFF0007861909000036.tif241170TIFF0007861909000037.tif241170TIFF0007861909000038.tif240170TIFF0007861909000039.tif240170TIFF0007861909000040.tif62170 Alternatively, replace "failureDetectionSet1-r17 and failureDetectionSet2-r17 are included" with "2 BFD RS sets are configured".

[0074] Alternatively, change the Explanation section 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, you can change the field description in IE, and the corresponding standard will be as follows:

[0076] (1) The standard for lowMobilityEvaluationConnected is shown in Table 3.

[0077] Table 3

[0078] [Table 14] TIFF0007861909000042.tif246170TIFF0007861909000043.tif246170TIFF0007861909000044.tif245170TIFF0007861909000045.tif247170TIFF0007861909000046.tif242170TIFF0007861909000047.tif59170 Alternatively, replace the condition with "if NR PSCell without mTRP".

[0079] (2) The criteria for goodServingCellEvaluationBFD are shown in Table 4.

[0080] Table 4

[0081] [Table 15] TIFF0007861909000049.tif246170TIFF0007861909000050.tif246170TIFF0007861909000051.tif246170TIFF0007861909000052.tif246170TIFF0007861909000053.tif241170TIFF0007861909000054.tif60170 Alternatively, replace it with "this SCell / SpCell without mTRP".

[0082] Alternatively, Scheme 1-1 may be implemented, for example, by describing it in a process description such as TS38.300 or TS38.331.

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

[0084] Table 5

[0085] [Table 16] TIFF0007861909000056.tif243170TIFF0007861909000057.tif75170 Alternatively, you can add the following description and replace "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] The process is described in TS38.331, and the corresponding criteria are shown in Table 6.

[0087] Table 6

[0088] [Table 17] Alternatively, 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 fault detection (BFD) measurement relaxation includes not evaluating whether the beam fault detection (BFD) measurement relaxation criteria at the serving cell are met.

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

[0091] For example, for a serving cell that consists of two BFD-RS sets, the criteria for the relaxation metric are not evaluated, or only the criteria for the relaxation metric are evaluated for a serving cell that does not consist of two BFD-RS sets.

[0092] In Scheme 1-2, whether the measurement relaxation criterion is met includes whether the low mobility criterion is met, for example, by referring to 5.7.13.1 of TS38.331, and / or whether the good cell quality criterion is met, for example, by referring to 5.7.13.2 of TS38.331.

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

[0094] In at least one embodiment of Scheme 1-2, Scheme 1-2 may be implemented by modifying TS 38.331, 5.7.13 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] The process may be explained in the process description of TIFF0007861909000061.tif243170TIFF0007861909000062.tif45170TS38.331, and the corresponding criteria may be 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] Scheme 1-3: In schemes 1-3, for serving cells that do not have two or more beam fault detection reference signal (BFD-RS) sets configured, terminal equipment is permitted to perform beam fault detection (BFD) measurement relaxation if the lower mobility criterion for beam fault detection (BFD) is met.

[0101] For example, if lower mobility criteria are met, terminal equipment may be permitted to perform BFD mitigation in a serving cell where two BFD-RS sets are not configured.

[0102] For example, TS 38.300 may be modified as shown in Table 9.

[0103] Table 9

[0104] [Table 20] TIFF0007861909000065.tif243170TIFF0007861909000066.tif53170<Example 2> Embodiment 2 of the present invention provides a method for measurement relaxation. This method is applied to a terminal device, for example, the terminal device 102 in Figure 1.

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

[0106] Step 301: For serving cells configured with two or more beam fault detection reference signal (BFD-RS) sets, the terminal equipment performs beam fault detection (BFD) measurement relaxation.

[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 serving cells configured with two or more beam fault detection reference signal (BFD-RS) sets, the terminal device does not transmit beam fault detection (BFD) measurement relaxation status information to the network device, or for serving cells not configured with two or more beam fault detection reference signal (BFD-RS) sets, the terminal device transmits beam fault detection (BFD) measurement relaxation status information to the network device.

[0109] For example, the BFD measurement relaxation status might not be reported for serving cells that consist of two BFD-RS sets, or the BFD measurement relaxation status might only be reported for serving cells that do not consist of two BFD-RS sets.

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

[0111] In step 302, the measurement relaxation status information for beam fault detection (BFD) is not transmitted to the network device. Do not trigger the reporting of measurement relaxation state information via the terminal device auxiliary information process. In the triggered terminal device auxiliary information process, the measurement relaxation state information is not included in the terminal device auxiliary information, or The triggered terminal device auxiliary information process includes at least one of setting the value of a bit corresponding to a serving cell in the terminal device auxiliary information to a first value, which is, for example, 0.

[0112] Step 303: For serving cells configured with two or more beam fault detection reference signal (BFD-RS) sets, the terminal device transmits beam fault detection (BFD) measurement relaxation status information to the network device.

[0113] For example, report the BFD measurement relaxation state for a serving cell that consists of two BFD-RS sets.

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

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

[0116] Embodiment A: In at least one embodiment of Embodiment A, the failure of a terminal device to transmit beam fault detection (BFD) measurement relaxation status information to a network device includes the fact that the terminal device is not configured to transmit beam fault detection (BFD) measurement relaxation status information to a network device.

[0117] For example, in a serving cell configured with two BFD-RS sets, the network device is configured so that the terminal device does not transmit the BFD measurement relaxation state to the network device.

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

[0119] For example, the network device is configured so that only for serving cells that do not have two BFD-RS sets configured, the terminal device transmits the BFD measurement relaxation state to the network device.

[0120] In at least one embodiment, TS 38.300 may be modified to implement Embodiment A, or the presence condition or field description of a third parameter relating to the beam fault detection relaxation reporting configuration (the third parameter being, for example, bfd-RelaxationReportingConfig) may be changed. Here, if the beam fault detection reference signal (BFD-RS) set is reconfigured, the terminal device stops the operating timer associated with the serving cell, which is, for example, T346j or T346k.

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

[0122] Table 10

[0123] [Table 21] Alternatively, modify the above content to: "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] The TS38.331 amendment may modify the existence condition for bfd-RelaxationReportingConfig, with the corresponding criteria shown in Table 11.

[0125] Table 11

[0126] [Table 22] TIFF0007861909000071.tif241170TIFF0007861909000072.tif241170TIFF0007861909000073.tif241170TIFF0007861909000074.tif228170 Alternatively, replace "failureDetectionSet1-r17 and failureDetectionSet2-r17 are included" with "2 BFD-RS sets are configured".

[0127] Alternatively, change the Explanation section to "The field is optionally present. Need R if failureDetectionSet1-r17 and failureDetectionSet2-r17 are not configured; otherwise, it is absent. Need R."

[0128] You may modify the field description of bfd-RelaxationReportingConfig and show the corresponding criteria in Table 12.

[0129] Table 12

[0130] [Table 23] TIFF0007861909000076.tif241170TIFF0007861909000077.tif241170TIFF0007861909000078.tif241170TIFF0007861909000079.tif241170TIFF0007861909000080.tif47170 Alternatively, replace the above description with "The network only includes this field if failureDetectionSet1-r17 and failureDetectionSet2-r17 are not included."

[0131] In at least one other embodiment, the failure of a terminal device to transmit beam fault detection (BFD) measurement relaxation state information to a network device includes assuming that the terminal device is not configured to transmit beam fault detection (BFD) measurement relaxation state information to a network device.

[0132] For example, in a serving cell configured with two BFD-RS sets, the terminal device is considered not to be configured by the network device to transmit the BFD measurement relaxation state to the network device itself.

[0133] Alternatively, in at least one other embodiment, the transmission of beam fault detection (BFD) measurement relaxation status information by a terminal device to a network device includes the assumption that the terminal device is configured to transmit beam fault detection (BFD) measurement relaxation status information to a network device.

[0134] For example, for a serving cell in which two BFD-RS sets are not configured, the terminal device is assumed to be configured by the network device to transmit the BFD measurement relaxation state to the network device itself.

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

[0136] Table 13

[0137] [Table 24] TIFF0007861909000082.tif238170TIFF0007861909000083.tif243170TIFF0007861909000084.tif244170TIFF0007861909000085.tif240170TIFF0007861909000086.tif89170 Embodiment B: In at least one embodiment of Embodiment B, the terminal device is configured to transmit beam fault detection (BFD) measurement relaxation state information to the network device, and if two or more beam fault detection reference signal (BFD-RS) sets are not configured for a serving cell, the terminal device transmits the measurement relaxation state information to the network device when the beam fault detection (BFD) measurement relaxation state in the serving cell of the terminal device changes and the minimum requirements of the terminal device are met.

[0138] In Embodiment B, the terminal device transmits measurement relaxation status information via terminal device auxiliary information.

[0139] For example, if a terminal device is configured to transmit beam fault detection (BFD) measurement relaxation status information to a network device, and does not consist of two BFD-RS sets for a serving cell, then when the terminal device changes its BFD relaxation status and the minimum requirements for the terminal device are met, the terminal device triggers a report of its BFD relaxation status via terminal device auxiliary information.

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

[0141] The minimum requirements for a terminal device refer, for example, to the minimum requirements for measuring a terminal device.

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

[0143] Table 14

[0144] [Table 25] In Embodiment B of TIFF0007861909000088.tif148170, the initiation of the terminal device auxiliary information process may be modified to include: when the beam fault detection (BFD) measurement relaxation state is changed in the radio link control connection (RRC_CONNECTED) state, and the terminal device is able to perform beam fault detection (BFD) measurement relaxation in the radio link control connection (RRC_CONNECTED) state, the terminal device initiates the terminal device auxiliary information process and transmits measurement relaxation state information to the network device to indicate the measurement relaxation state of a serving cell in which two or more (e.g., two) beam fault detection reference signal (BFD-RS) sets are not configured.

[0145] The following describes step 303.

[0146] In step 303, for serving cells configured with two or more beam fault detection reference signal (BFD-RS) sets, the terminal device transmits beam fault detection (BFD) measurement relaxation status information to the network device.

[0147] In step 303, the terminal device may transmit together the measurement relaxation status information of serving cells configured with two or more beam fault detection reference signal (BFD-RS) sets and the measurement relaxation status information of serving cells not configured with two or more beam fault detection reference signal (BFD-RS) sets to the network device. For example, the measurement relaxation status information of serving cells configured with two or more beam fault detection reference signal (BFD-RS) sets and the measurement relaxation status information of serving cells not configured with two or more beam fault detection reference signal (BFD-RS) sets may be transmitted to the network device in the same bitstream.

[0148] Alternatively, in step 303, the terminal device may separately transmit to the network device the measurement relaxation status information for serving cells configured with two or more beam fault detection reference signal (BFD-RS) sets and the measurement relaxation status information for serving cells not configured with two or more beam fault detection reference signal (BFD-RS) sets. For example, the measurement relaxation status information for serving cells configured with two or more beam fault detection reference signal (BFD-RS) sets and the measurement relaxation status information for serving cells not configured with two or more beam fault detection reference signal (BFD-RS) sets may be transmitted to the network device in different bitstreams (e.g., two bitstreams).

[0149] In at least one embodiment of step 303, when measurement relaxation state information for a serving cell configured with two or more beam fault detection reference signal (BFD-RS) sets and measurement relaxation state information for a serving cell not configured with two or more beam fault detection reference signal (BFD-RS) sets are transmitted together to a network device, the measurement relaxation state includes the measurement relaxation state of one beam fault 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 first BFD-RS set that appears 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 transmit / receive point (TRP) performing non-terminal device specific or terminal device specific transmission.

[0151] In at least one other embodiment of step 303, if the terminal device transmits to the network device together or separately measurement relaxation state information for serving cells configured with two or more beam fault detection reference signal (BFD-RS) sets and measurement relaxation state information for serving cells not configured with two or more beam fault detection reference signal (BFD-RS) sets, the measurement relaxation state includes whether the measurement relaxation states of the two or more beam fault 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, which is, for example, 0. Alternatively, if the measurement relaxation states of two or more beam fault detection reference signal (BFD-RS) sets match, a second value is indicated, which is, for example, 1.

[0153] In at least one other embodiment of step 303, if the terminal device transmits to the network device together or separately measurement relaxation state information for serving cells configured with two or more beam fault detection reference signal (BFD-RS) sets and measurement relaxation state information for serving cells not configured with two or more beam fault detection reference signal (BFD-RS) sets, the measurement relaxation state includes the measurement relaxation state for two or more beam fault detection reference signal (BFD-RS) sets.

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

[0155] In at least one embodiment of step 303, when a terminal device transmits measurement relaxation status information for serving cells configured with two or more beam fault detection reference signal (BFD-RS) sets, and measurement relaxation status information for serving cells not configured with two or more beam fault detection reference signal (BFD-RS) sets, together or separately, the measurement relaxation status information has the same number of first information bits as the number of beam fault detection reference signal (BFD-RS) sets, each first information bit indicating whether the corresponding beam fault detection reference signal (BFD) set performs measurement relaxation of beam fault detection (BFD).

[0156] Figure 4 is a schematic diagram of another example of the measurement relaxation method according to Example 2, which is applied to a terminal device.

[0157] As shown in Figure 4, the method for mitigating the measurement includes the following steps.

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

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

[0160] In other cases, this includes the configuration of two or more beam fault detection reference signal (BFD-RS) sets for the serving cell.

[0161] <Example 3> Embodiment 3 of the present invention provides a method for measurement relaxation. This method is applied to a network terminal device, for example, the network device 101 in Figure 1.

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

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

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

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

[0166] Step 503: For serving cells configured with two or more beam fault detection reference signal (BFD-RS) sets, configure the terminal device not to transmit beam fault detection (BFD) measurement relaxation status information to the network device, or for serving cells not configured with two or more beam fault detection reference signal (BFD-RS) sets, configure the terminal device to transmit beam fault detection (BFD) measurement relaxation status information to the network device.

[0167] Step 503 may be achieved by changing the existence condition or field description of the third parameter (bfd-RelaxationReportingConfig) relating to the beam fault detection relaxation reporting configuration.

[0168] Step 504: For a serving cell configured with two or more beam fault detection reference signal (BFD-RS) sets, configure the terminal device to transmit beam fault detection (BFD) measurement relaxation status information to the network device.

[0169] In step 504, the network device receives together or separately measurement relaxation status information for serving cells configured with two or more beam fault detection reference signal (BFD-RS) sets, and measurement relaxation status information for serving cells not configured with two or more beam fault detection reference signal (BFD-RS) sets.

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

[0171] Here, one beam fault detection reference signal (BFD-RS) set is comprised of network equipment, 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 transmit / receive point (TRP) performing non-terminal specific or terminal 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 coincide.

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

[0174] In at least one other embodiment of step 504, the measurement relaxation state includes the measurement relaxation state of 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 performing beam fault detection (BFD) measurement relaxation, the second value (1) is shown; otherwise, the first value (0) is shown. Alternatively, if two or more beam fault detection reference signal (BFD-RS) sets are not performing beam fault detection (BFD) measurement relaxation, the first value (0) is shown; otherwise, the second value (1) is shown.

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

[0177] <Example 4> Embodiment 4 of the present invention provides a device for measurement relaxation applied to a terminal device. The device corresponds to the method for measurement relaxation of Embodiment 1.

[0178] Figure 6 is a schematic diagram of an example of a device for measurement relaxation according to Embodiment 4. As shown in Figure 6, the device for measurement relaxation 600 includes a first application section 601.

[0179] The first application unit 601 prevents the terminal device from performing beam fault detection (BFD) measurement relaxation for serving cells configured with two or more beam fault detection reference signal (BFD-RS) sets, or enables the terminal device to perform beam fault detection (BFD) measurement relaxation for serving cells not configured with two or more beam fault detection reference signal (BFD-RS) sets.

[0183] In at least one embodiment, modifying the presence condition or field description of the first parameter (lowMobilityEvaluationConnected) relating to low mobility criteria includes disabling or enabling beam fault detection (BFD) measurement relaxation if the serving cell is a special cell and there is a first serving cell in the cell set to which the serving cell is located that does not have two or more beam fault detection reference signal (BFD-RS) sets configured.

[0184] In at least one embodiment, not performing beam fault detection (BFD) measurement relaxation includes not evaluating whether the beam fault detection (BFD) measurement relaxation criteria at the serving cell are met.

[0185] In at least one embodiment, performing beam fault detection (BFD) measurement relaxation includes evaluating whether the beam fault detection (BFD) measurement relaxation criteria at the serving cell are met.

[0186] In at least one embodiment, whether a measurement relaxation criterion is met includes whether a low mobility criterion is met and / or whether a good cell quality criterion is met.

[0187] In at least one embodiment, determining whether a low mobility criterion is met includes evaluating whether the low mobility criterion is met if the cell set in which the serving cell is located does not have two or more beam fault detection reference signal (BFD-RS) sets configured.

[0188] In at least one embodiment, for a serving cell in which two or more beam fault detection reference signal (BFD-RS) sets are not configured, the terminal equipment is permitted to perform beam fault detection (BFD) measurement relaxation if a lower mobility criterion for beam fault detection (BFD) is met.

[0190] Figure 7 is a schematic diagram of an example of a device for measurement relaxation according to Embodiment 5. As shown in Figure 7, the device for measurement relaxation 700 includes a second application section 701.

[0191] The second application unit 701 causes the terminal device to perform beam fault detection (BFD) measurement relaxation for serving cells configured with two or more beam fault detection reference signal (BFD-RS) sets.

[0192] In at least one embodiment, for a serving cell configured with two or more beam fault detection reference signal (BFD-RS) sets, the second application prevents the terminal device from transmitting beam fault detection (BFD) measurement relaxation status information to the network device.

[0200] In at least one embodiment, if a terminal device is configured to transmit beam fault detection (BFD) measurement relaxation state information to a network device, and no more than two beam fault detection reference signal (BFD-RS) sets are configured for a serving cell, the second application causes the terminal device to transmit measurement relaxation state information to a network device when the beam fault detection (BFD) measurement relaxation state in the serving cell of the terminal device changes and the minimum requirements of the terminal device are met.

[0201] In at least one embodiment, the second application unit causes the terminal device to transmit measurement relaxation state information via terminal device auxiliary information.

[0203] In at least one embodiment, when the beam fault detection (BFD) measurement relaxation state is changed in the radio link control connection (RRC_CONNECTED) state, and when the terminal device is capable of performing beam fault detection (BFD) measurement relaxation in the radio link control connection (RRC_CONNECTED) state, the second application unit causes the terminal device to initiate a terminal device auxiliary information process and transmit measurement relaxation state information to the network device to indicate the measurement relaxation state of a serving cell in which two or more beam fault detection reference signal (BFD-RS) sets are not configured.
