Description

[0001] The present disclosure is a divisional application, the original application number of which is 202180003421.8, the filing date of which is October 21, 2021, and the original application invention name of which is "Communication method and device based on measurement relaxation mechanism and storage medium". TECHNICAL FIELD

[0002] The present disclosure relates to the technical field of communication, in particular to a communication method and device based on a measurement relaxation mechanism and a storage medium. BACKGROUND

[0003] In related technologies, a low-mobility measurement relaxation mechanism is introduced for a connected terminal. For example, radio resource management (RRM) measurement relaxation, radio link monitoring (RLM) measurement relaxation, and beam failure detection (BFD) measurement relaxation.

[0004] Among them, the RRM measurement of the connected state is mainly the measurement of the neighboring cell, and the signal quality of the reference signal of the current serving cell is taken as the judgment basis when the connected state RRM measurement relaxation decision is made. Among them, the reference signal used for RRM measurement can be a synchronization signal block (SSB) or a channel state information reference signal (CSI-RS). The RLM measurement of the connected state is the measurement of the downlink radio link quality monitoring performed by the connected UE in the active bandwidth part (BWP), and the network configures a reference signal set for the terminal to perform RLM measurement. The reference signal in this reference signal set is called RLM-RS. The BFD measurement of the connected state is the measurement of the downlink beam quality monitoring performed by the connected terminal in the active BWP, and the network configures a reference signal set for the terminal to perform BFD measurement. The reference signal in this reference signal set is called BFD-RS. In the current protocol TS 38.331, the RLM-RS and BFD-RS configured by the network can be SSB and / or CSI-RS.

[0005] RLM / BFD measurement relaxation and RRM measurement relaxation can both be based on low-mobility decision criteria, that is, both are based on the signal quality of a serving cell to determine whether relaxation can be performed. However, in the related art, measurement evaluation needs to be performed based on the reference signal configured for RRM for RRM measurement relaxation, and based on the reference signal configured for RLM / BFD for RLM / BFD measurement relaxation, which has a large signaling overhead.

[0056] The example embodiments will be described in detail herein with reference to the attached drawings. The description of the example embodiments is intended to apply to any example embodiment, unless specifically noted.

The 5G network can also be referred to as a new radio network (New Radio, NR). For convenience of description, the wireless communication network is sometimes referred to as a network in the present disclosure.

[0060] Further, the network device involved in the present disclosure can also be referred to as a wireless access network device.

It should be understood that the specific technology and specific device form adopted by the network device in the embodiments of the present disclosure are not limited.

[0061] Further, the terminal involved in the present disclosure can also be referred to as a terminal device, a user equipment (UE), a mobile station (MS), a mobile terminal (MT), etc., and is a device that provides voice and / or data connectivity for a user, for example, a handheld device having wireless connection function, a vehicle-mounted device, etc. At present, some examples of the terminal are: a mobile phone, a pocket personal computer (PPC), a palm computer, a personal digital assistant (PDA), a notebook computer, a tablet computer, a wearable device, or a vehicle-mounted device, etc. In addition, when it is a vehicle-to-everything (V2X) communication system, the terminal device can also be a vehicle-mounted device. It should be understood that the specific technology and specific device form adopted by the terminal in the embodiments of the present disclosure are not limited.

[0062] In order to save the terminal power consumption in the related art, in Rel-16 version, the RRM measurement relaxation mechanism is introduced for the terminal in an idle state. In the measurement relaxation mechanism, the communication is mainly based on the measurement relaxation decision criterion. In the related art, the measurement relaxation criterion includes a low-mobility decision criterion.

[0063] The low-mobility decision criterion refers to that, within a certain time (T SearchDeltaP ), if the difference between the reference received signal strength (S rxlevRef ) and the signal strength (S rxlev ) of the current serving cell of the terminal is less than a preset threshold value (S SearchDeltaP), it means that the signal change of the terminal is not large, and it is considered that the terminal is currently in a low mobility state. Among them, the parameters S SearchDeltaP , T SearchDeltaP are provided by the network, and the formula is agreed by the protocol.

[0064] Among them, the low mobility judgment criterion described in TS38.304 protocol is as follows: Relaxed measurement criterion for UE with low mobility If the UE meets (Srxlev Ref – Srxlev)<S SearchDeltaP , it is considered that the UE meets the low mobility criterion, wherein: (The relaxed measurement criterion for UE with low mobility is fulfilled when: -(Srxlev Ref – Srxlev)<S SearchDeltaP , Where: ) -Srxlev is the signal quality of the current service cell (dB) (Srxlev = current Srxlev value of the serving cell (dB). -Srxlev Ref is the reference signal quality of the previous service cell (dB) (Srxlev Ref = reference Srxlev value of the serving cell (dB)), if: After selecting or reselecting a new cell, or (Srxlev - SrxlevRef)>0, or If the relaxed measurement criterion has not been met for TSearchDeltaP , update Srxlev Ref to the signal quality of the UE's current service cell (The UE shall set the value of Srxlev Refto the current Srxlev value of the serving cell); Currently, 3GPP introduces more advanced measurement relaxation criteria in Rel-17 version, and also introduces RRM measurement relaxation to connected state. The RRM measurement of connected state is mainly the measurement of neighbor cell. In the decision of connected state RRM measurement relaxation, currently in the R17 low capability terminal (RedCap) project, it is considered to follow the R16 idle state RRM measurement relaxation low mobility decision criteria, and the signal quality of the reference signal of the current serving cell is used as the judgment basis. Among them, the reference signal used for RRM measurement can be SSB or CSI-RS.

[0065] In related technologies, the measurement relaxation mechanism of connected state also introduces RLM measurement relaxation and BFD measurement relaxation and other communication link quality monitoring measurement relaxations. Among them, RLM measurement relaxation is the measurement of downlink radio link quality monitoring performed by the connected state terminal in the active BWP. The network configures a reference signal set for the terminal to perform RLM measurement. The reference signal in the reference signal set is called RLM-RS. Among them, the number of RLM-RS is configured based on Frame 1 (FR1) or Frame 2 (FR2). FR1 and FR2 are divided based on 6GHz frequency. The frequency band below 6GHz is FR1, and the frequency band above 6GHz is FR2. The maximum number of configured RLM-RS is: 2 in the case of FR1≤3GHz. In the case of FR1>3GHz, it is 4. In the FR2 frequency band, it is 8. BFD measurement relaxation is the measurement of downlink beam quality monitoring performed by the connected state terminal in the active BWP. The network configures a reference signal set for the terminal to perform BFD measurement. The reference signal in the reference signal set is called BFD-RS, and at most 2 are configured.

[0066] In the current protocol TS 38.331, the terminal receives the RLM-RS and BFD-RS configured by the NR network, which can be SSB and / or CSI-RS. The terminal receives the reference signal used for RRM measurement in the NR network, which can be SSB or CSI-RS: In related technologies, the network configures the reference signal resource set for RRM measurement based on SSB or CSI-RS through radio resource control signaling (Radio Resource Control, RRC) messages. The network configures the reference signal resource set for RLM and / or BFD measurement through RRC messages.

[0067] RLM / BFD measurement relaxation and RRM measurement relaxation can both be based on low-mobility decision criteria. In other words, RLM / BFD measurement relaxation and RRM measurement relaxation can both be based on the signal quality of a serving cell to determine whether relaxation can be performed. Therefore, for RLM / BFD measurement relaxation and RRM measurement relaxation, when the measurement relaxation decision is made based on the signal quality of the serving cell, the current solution needs to evaluate two sets of measurement reference signals respectively, and the reference signal configured for RRM is used for measurement evaluation for RRM measurement relaxation, and the reference signal configured for RLM / BFD is used for measurement evaluation for RLM / BFD measurement relaxation, which has a large signaling overhead.

[0068] Therefore, the embodiments of the present disclosure provide a communication method based on a measurement relaxation mechanism, in which a reference signal common to RRM measurement relaxation and communication link quality monitoring measurement relaxation is used for measurement relaxation, and the RRM measurement relaxation and the communication link quality monitoring measurement relaxation are determined based on the common reference signal.

[0069] In the embodiments of the present disclosure, the reference signal common to RRM measurement relaxation and communication link quality monitoring measurement relaxation is referred to as a common measurement reference signal.

[0070] It can be understood that the communication link quality monitoring measurement relaxation involved in the embodiments of the present disclosure can be RLM measurement relaxation and / or BFD measurement relaxation, that is, it can be RLM measurement relaxation, it can be BFD measurement relaxation, or it can be RLM measurement relaxation and BFD measurement relaxation.

[0071] Figure 2 FIG. 1 is a flowchart of a communication method based on a measurement relaxation mechanism according to an exemplary embodiment. Figure 2 As shown in FIG. 1, the communication method based on the measurement relaxation mechanism is used in a terminal, and includes the following steps.

[0072] In step S11, a common measurement reference signal is determined, which is a reference signal common to RRM measurement relaxation and communication link quality monitoring measurement relaxation.

[0073] In step S12, the RRM measurement relaxation and the communication link quality monitoring measurement relaxation are determined based on the common measurement reference signal.

[0074] In the embodiments of the present disclosure, the determined common measurement reference signal can be SSB and / or CSI-RS.

[0075] Based on the common measurement reference signal, the measurement relaxation decision of the RRM measurement relaxation and the communication link quality monitoring measurement relaxation can be understood as that, for a terminal supporting both the RRM measurement relaxation and the RLM / BFD communication link quality monitoring measurement relaxation, the measurement results (for example, Reference Signal Receiving Power, RSRP) based on the same set of reference signals are used for the low mobility relaxation decision criterion.

[0076] In the embodiments of the present disclosure, based on the common measurement reference signal of the RRM measurement relaxation and the communication link quality monitoring measurement relaxation, the measurement relaxation decision of the RRM measurement relaxation and the communication link quality monitoring measurement relaxation can be based on the common reference signal quality, thereby reducing the signaling overhead and achieving a simple and efficient cooperative measurement.

[0077] In the following, the communication method based on the measurement relaxation mechanism based on the common measurement reference signal will be described.

[0078] In one implementation of the embodiments of the present disclosure, the common measurement reference signal is determined based on terminal measurement. In another implementation, the common measurement reference signal is determined based on network indication.

[0079] First, the implementation of determining the common measurement reference signal based on terminal measurement will be described.

[0080] In the embodiments of the present disclosure, the common measurement reference signal is determined based on terminal measurement, which can be determined based on the reference signal type used by the RRM measurement relaxation and the reference signal type used by the communication link quality monitoring measurement relaxation.

[0081] Figure 3 A flowchart of a communication method based on a measurement relaxation mechanism according to an exemplary embodiment is shown, which can be implemented alone or in combination with other embodiments. As shown in Figure 3 The communication method based on the measurement relaxation mechanism is used in a terminal, which includes the following steps.

[0082] In step S21, in response to the same reference signal type used by the RRM measurement relaxation and the communication link quality monitoring measurement relaxation, the reference signals with the same signal index in the same reference signal type are used as the common measurement reference signal.

[0083] In an embodiment of the present disclosure, on one hand, the reference signal type used for RRM measurement relaxation can be configured by the network. The terminal determines the reference signal type used for RRM measurement relaxation when performing RRM measurement. On the other hand, the same reference signal type used for communication link quality monitoring measurement relaxation can be configured by the network. The terminal determines the reference signal type used for communication link quality monitoring measurement relaxation when performing communication link quality monitoring measurement.

[0084] In an embodiment of the present disclosure, the reference signal type used for RRM measurement relaxation can include SSB or CSI-RS, and the same reference signal type used for communication link quality monitoring measurement relaxation can include at least one of SSB and CSI-RS.

[0085] In an embodiment, the same reference signal type used for RRM measurement relaxation and communication link quality monitoring measurement relaxation includes at least one of the following: A: the reference signal used for RRM measurement relaxation is SSB, the reference signal used for communication link quality monitoring measurement relaxation is SSB, and the same reference signal type is SSB.

[0086] B: the reference signal used for RRM measurement relaxation is CSI-RS, the reference signal used for communication link quality monitoring measurement relaxation is CSI-RS, and the same reference signal type is CSI-RS.

[0087] C: the reference signal used for RRM measurement relaxation is SSB or CSI-RS, the reference signal used for communication link quality monitoring measurement relaxation is SSB and CSI-RS, and the same reference signal type is SSB or CSI-RS.

[0088] In an embodiment of the present disclosure, based on the determined same reference signal type, a reference signal with the same signal index in the same reference signal type is further determined as a common measurement reference signal.

[0089] For example, the same reference signal type is SSB, and the SSB with the same SSB index used for RRM measurement relaxation and communication link quality monitoring measurement relaxation is the common measurement reference signal.

[0090] For another example, the same reference signal type is CSI-RS, and the CSI-RS with the same SSB index used for RRM measurement relaxation and communication link quality monitoring measurement relaxation is the common measurement reference signal.

[0091] In the embodiments of the present disclosure, the measurement relaxation decision is made based on the common measurement reference signal when performing RRM measurement relaxation and communication link quality monitoring measurement relaxation such as RLM and / or BFD. That is, the RRM measurement relaxation and the communication link quality monitoring measurement relaxation such as RLM and / or BFD are based on the same measurement reference signal for the measurement relaxation decision, so as to save the signaling overhead.

[0092] In one embodiment, in response to that the RRM measurement relaxation uses SSB and the communication link quality monitoring measurement relaxation uses SSB, the same reference signal used by the RRM measurement relaxation and the communication link quality monitoring measurement relaxation is the SSB with the same SSB index. The terminal makes the measurement relaxation decision for the RRM measurement relaxation and the communication link quality monitoring measurement relaxation based on the SSB with the same SSB index. In one example, if the RRM and the communication link quality monitoring are both based on the SSB as the measurement reference signal, the terminal determines the SSB index commonly used for the communication link quality monitoring measurement and the RRM measurement, and uses the measurement result of the common SSB index as the basis for determining whether the terminal enters the RRM low-mobility relaxation and the communication link quality monitoring low-mobility relaxation.

[0093] In one embodiment, in response to that the RRM measurement relaxation uses CSI-RS and the communication link quality monitoring measurement relaxation uses CSI-RS, the same reference signal used by the RRM measurement relaxation and the communication link quality monitoring measurement relaxation is the CSI-RS with the same CSI-RS index. The terminal makes the measurement relaxation decision for the RRM measurement relaxation and the communication link quality monitoring measurement relaxation based on the CSI-RS with the same CSI-RS index. In one example, if the RRM and the communication link quality monitoring are both based on the CSI-RS as the measurement reference signal, the terminal determines the CSI-RS commonly used for the communication link quality monitoring and the RRM measurement, and uses the measurement result of the common CSI-RS index as the basis for determining whether the terminal enters the RRM low-mobility relaxation and the communication link quality monitoring low-mobility relaxation.

[0094] In one embodiment, in response to RRM measurement relaxation using SSB, and communication link quality monitoring measurement relaxation using SSB and CSI-RS, the same reference signal used by RRM measurement relaxation and communication link quality monitoring measurement relaxation is SSB with the same SSB index. The terminal makes measurement relaxation decision for RRM measurement relaxation based on SSB with the same SSB index, and for communication link quality monitoring measurement relaxation based on CSI-RS and SSB with the same SSB index. In other words, if the network configures the terminal to make RRM measurement relaxation based on SSB, the terminal makes RRM measurement relaxation decision based on SSB with the same SSB index as the SSB used for communication link quality monitoring measurement relaxation. If the terminal makes communication link quality monitoring measurement relaxation, and the network configures the terminal to make measurement based on SSB and CSI-RS, the terminal needs to make communication link quality monitoring measurement relaxation decision based on CSI-RS in addition to SSB with the same SSB index as the SSB used for RRM measurement relaxation.

[0095] Or in another embodiment, in response to RRM measurement relaxation using CSI-RS, and communication link quality monitoring measurement relaxation using SSB and CSI-RS, the same reference signal used by RRM measurement relaxation and communication link quality monitoring measurement relaxation is CSI-RS with the same CSI-RS index. The terminal makes measurement relaxation decision for RRM measurement relaxation based on CSI-RS with the same CSI-RS index, and for communication link quality monitoring measurement relaxation based on SSB and CSI-RS with the same CSI-RS index. In other words, if the network configures the terminal to make RRM measurement relaxation based on CSI-RS, the terminal makes RRM measurement relaxation decision based on CSI-RS with the same CSI-RS index as the CSI-RS used for communication link quality monitoring measurement relaxation. If the network configures the terminal to make communication link quality monitoring measurement relaxation based on SSB and CSI-RS, the terminal needs to make communication link quality monitoring measurement relaxation decision based on SSB in addition to CSI-RS with the same CSI-RS index as the CSI-RS used for RRM measurement relaxation.

[0096] In one example, for the case of using both SSB and CSI-RS as reference signal for communication link quality monitoring, the low-mobility relaxation decision for communication link quality monitoring and RRM is made using the measurement results of the reference signal with the same type and common index as the measurement reference signal type of RRM.

[0097] It can be understood that the above-mentioned embodiments of the present disclosure are implemented in dependence on the reference signals having the same reference signal type and the same signal index between the reference signals configured by the RRM measurement relaxation and the communication link quality monitoring measurement relaxation. In an implementation, if the reference signals configured by the RRM measurement relaxation and the communication link quality monitoring measurement relaxation do not have the same reference signal type and / or do not have the same signal index, the RRM measurement relaxation and the communication link quality monitoring measurement relaxation each make a measurement relaxation decision according to the corresponding configured reference signal type.

[0098] The implementation process of determining the common measurement reference signal based on the network indication is described below according to an embodiment of the present disclosure.

[0099] In an embodiment of the present disclosure, the network device can send indication information to the terminal to indicate the terminal to perform the common measurement reference signal shared by the RRM measurement relaxation and the communication link quality monitoring measurement relaxation. For the convenience of description, the indication information sent by the network device to indicate the common measurement reference signal is referred to as first indication information.

[0100] Figure 4 FIG. 1 is a flowchart of a communication method based on a measurement relaxation mechanism according to an exemplary embodiment. The communication method based on the measurement relaxation mechanism can be implemented alone or in combination with other embodiments. As shown in FIG. 1, the communication method based on the measurement relaxation mechanism is used in a terminal and includes the following steps. Figure 4

[0101] In step S31, the first indication information sent by the network device is received, and the first indication information is used to indicate the common measurement reference signal.

[0102] In an embodiment of the present disclosure, the terminal receives the first indication information sent by the network device, and regards the reference signal indicated by the first indication information as the common measurement reference signal.

[0103] In an embodiment of the present disclosure, the common measurement reference signal indicated by the first indication information can be a reference signal set. The reference signal set includes one or more reference signals.

[0104] In an implementation, the common measurement reference signal is determined based on the intersection between the reference signal set used by the configured RRM measurement relaxation and the reference signal set used by the configured communication link quality monitoring measurement relaxation. For example, the network device determines the intersection between the reference signal set used by the RRM measurement relaxation and the reference signal set used by the communication link quality monitoring measurement relaxation as the common measurement reference signal. In another implementation, the common measurement reference signal is a self-defined reference signal set. For example, the network device autonomously configures a group of reference signals as the common measurement reference signal. ​

[0105] In an aspect of the embodiments of the present disclosure, the first indication information can be carried in a dedicated RRC, and the terminal receives the first indication information sent by the network device based on the dedicated RRC signaling. On the other hand, the first indication information can also be configured to the terminal together with the low-mobility relaxation criterion configuration parameter, and the terminal receives the first indication information sent by the network device based on the low-mobility relaxation criterion configuration parameter.

[0106] In the implementation of the present disclosure provided above, the determination of the relaxation of the RRM measurement and the relaxation of the communication link quality monitoring measurement based on the common measurement reference signal can be determined by the indication information sent by the network. The indication information is referred to as second indication information below, and the second indication information is used to indicate the determination of the relaxation of the RRM measurement and the relaxation of the communication link quality monitoring measurement using the common measurement reference signal. The second indication information can be understood as a flag indication configured by the network device to indicate whether the terminal is allowed to use the common reference signal to determine the low-mobility relaxation of the RRM and the BFD.

[0107] In an implementation, the terminal receives the second indication information, and then determines the relaxation of the RRM measurement and the relaxation of the communication link quality monitoring measurement using the common measurement reference signal. In another implementation, the terminal does not receive the second indication information, and then determines the relaxation of the RRM measurement using the RRM-RS and determines the relaxation of the communication link quality monitoring measurement using the corresponding reference signal of the relaxation of the communication link quality monitoring measurement.

[0108] It can be understood that the relaxation of the communication link quality monitoring measurement involved in the above embodiments of the present disclosure includes the RLM measurement relaxation and / or the BFD measurement relaxation. In other words, in the embodiments of the present disclosure, the RLM measurement relaxation and the RRM measurement relaxation can use the common measurement reference signal for the determination of the relaxation, or the BFD measurement relaxation and the RRM measurement relaxation can use the common measurement reference signal for the determination of the relaxation, or the RLM measurement relaxation, the BFD measurement relaxation and the RRM measurement relaxation can use the common measurement reference signal for the determination of the relaxation.

[0109] The following exemplary descriptions are given respectively with the relaxation of the communication link quality monitoring measurement including the RLM measurement relaxation and the relaxation of the communication link quality monitoring measurement including the BFD measurement relaxation.

[0110] First, the RLM measurement relaxation and the RRM measurement relaxation are described.

[0111] Scheme 1: Terminal measurement ① If both RRM and RLM are based on SSB as measurement reference signal, the terminal judges the SSB index which is common for RLM and RRM measurement, and uses the measurement result of the common SSB index as the basis for judging whether the terminal enters the RRM and RLM low-mobility relaxation; ② If both RRM and RLM are based on CSI-RS as measurement reference signal, the terminal judges the CSI-RS which is common for RLM and RRM measurement, and uses the measurement result of the common CSI-RS index as the basis for judging whether the terminal enters the RRM and RLM low-mobility relaxation; ③ If RLM is based on both SSB and CSI-RS as reference signal, at this time, according to the measurement reference signal type of RRM, for the same type of reference signal, the RLM and RRM use the measurement result of the common index for relaxation judgment; ④ If RRM and RLM are based on completely different reference signal types, then each according to the corresponding reference signal type to judge whether to relax; For this scheme, the network can indicate whether the terminal is allowed to use the common reference signal for RRM and RLM low-mobility measurement relaxation judgment through the switch (Flag).

[0112] Scheme 2: Network indication The network indicates the reference signal used by the terminal for low-mobility criterion judgment, denoted as common-RS, which is used for RRM and RLM measurement relaxation judgment: Wherein, the common-RS can be the intersection of RLM-RS and RRM-RS, or a set of reference signals configured by the network autonomously; Further, the common-RS indication can be issued to the terminal through dedicated RRC signaling, or along with the configuration of low-mobility relaxation criteria parameters to the terminal; For the implementation process of the above-mentioned RRM and RLM low-mobility measurement relaxation judgment based on the same index measurement reference signal, please refer to Figure 5 . Figure 5 The SSB index and signal quality diagram for RRM and RLM low-mobility measurement relaxation judgment based on SSB. Please refer to Figure 5 The SSB index includes {0, 1, 2, 3, 4, 5, 6, 7}, a total of eight SSB indexes. The network device configures the SSB index used for RRM measurement as {0, 1, 2} through the bit bitmap "11111000". The network device configures the reference signal for RLM measurement as {0, 1, 2}.

[0113] In one solution, the terminal performs measurement based on the common index, i.e., {0, 1, 2}, and the relevant measurement result is used as the basis for determining whether RRM and RLM are in low-mobility relaxation. In another solution, the network simultaneously issues the reference signal set {0, 1, 2} for measurement when issuing the low-mobility criterion parameters, indicating the reference signal for the terminal to perform relevant measurement.

[0114] Secondly, BFD measurement relaxation and RRM measurement relaxation are described.

[0115] Solution 1: Terminal measurement 1. If both RRM and BFD are based on SSB as the measurement reference signal, the terminal determines the SSB index commonly used for BFD and RRM measurement, and uses the measurement result of the common SSB index as the basis for determining whether the terminal enters RRM and BFD low-mobility relaxation.

[0116] 2. If both RRM and BFD are based on CSI-RS as the measurement reference signal, the terminal determines the CSI-RS commonly used for BFD and RRM measurement, and uses the measurement result of the common CSI-RS index as the basis for determining whether the terminal enters RRM and BFD low-mobility relaxation.

[0117] 3. If BFD is based on both SSB and CSI-RS as the reference signal, according to the measurement reference signal type of RRM, for the same type of reference signal with a common index, BFD and RRM use the measurement result of the common index for relaxation determination.

[0118] 4. If RRM and BFD are based on completely different reference signal types, they are determined according to the corresponding reference signal type whether to relax.

[0119] For this solution, the network can indicate whether the terminal is allowed to use the common reference signal for RRM and BFD low-mobility measurement relaxation determination through a switch (Flag).

[0120] Solution 2: Network indication The network indicates the reference signal used by the terminal to determine the low-mobility criterion, denoted as common-RS, which is used for RRM and BFD measurement relaxation determination: The common-RS can be the intersection of BFD-RS and RRM-RS, or a set of reference signals configured by the network.

[0121] The common-RS indication can be issued to the terminal through dedicated RRC signaling, or along with the low-mobility relaxation criterion parameters configured to the terminal.

[0122] The method for communicating based on the measurement relaxation mechanism provided in the embodiments of the present disclosure can simultaneously determine the low mobility criteria of RRM and RLM or the low mobility criteria of RRM and BFD based on the same set of reference signal quality, and thus the coordinated measurement is more efficient and concise.

[0123] Based on the same concept, the embodiments of the present disclosure further provide a method for communicating based on a measurement relaxation mechanism applied to a network device.

[0126] In step S42, first indication information is sent. The first indication information is used to indicate the common measurement reference signal.

[0127] The common measurement reference signal indicated by the first indication information in the embodiments of the present disclosure can be a set of reference signals. The set of reference signals includes one or more reference signals.

[0128] In an implementation, the common measurement reference signal is determined based on the intersection between the set of reference signals used by the configured RRM measurement relaxation and the set of reference signals used by the configured communication link quality monitoring measurement relaxation.
