Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of communication, and particularly relates to a communication method and device based on a measurement relaxation mechanism and a storage medium. BACKGROUND

[0002] In the related art, 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.

[0003] 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. 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 link quality monitoring of the active bandwidth part (BWP) of the connected UE, and 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. The BFD measurement of the connected state is the measurement of the downlink beam quality monitoring of the active BWP of the connected terminal, and 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. In the current protocol TS 38.331, the RLM-RS and BFD-RS configured by the network can be SSB and / or CSI-RS.

[0004] Both RLM / BFD measurement relaxation and RRM measurement relaxation can be based on the low-mobility decision criterion, that is, both are based on the signal quality of the 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.

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.

[0079] 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.

[0080] The low-mobility decision criterion refers to that the difference between the reference received signal strength (S SearchDeltaP ) and the signal strength (S rxlevRef ) of the current serving cell of the terminal is less than a preset threshold value (S rxlev ) in a certain time (T SearchDeltaP) is not large, 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.

[0081] Among them, the low mobility decision criterion described in the TS38.304 protocol is as follows:

[0082] Relaxed measurement criterion for UE with low mobility

[0083] If the UE meets (Srxlev Ref –Srxlev)<S SearchDeltaP , it is considered that the UE meets the low mobility criterion, wherein:

[0084] (The relaxed measurement criterion for UE with low mobility isfulfilled when:

[0085] -(Srxlev Ref –Srxlev)<S SearchDeltaP ,Where:)

[0086] -Srxlev is the signal quality of the current service cell (dB) (Srxlev=Srxlev value of the serving cell (dB).

[0087] -Srxlev Ref is the reference signal quality of the previous service cell (dB) (Srxlev Ref =Srxlev value of the serving cell (dB)), if:

[0088] · After selecting or reselecting a new cell, or

[0089] · (Srxlev-SrxlevRef)>0, or

[0090] · If the relaxed measurement criterion has not been met for TSearchDeltaP

[0091] Srxlev = Srxlev - (Srx-Pmax * (Pmax - Pcurrent)) Ref The UE shall set the value of Srxlev to the current Srxlev value of the serving cell. Ref

[0092] 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 for the measurement of neighbor cells. 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 criterion, and the signal quality of the reference signal of the current serving cell is used as the judgment basis. Among them, the reference signal for RRM measurement can be SSB or CSI-RS.

[0093] In the related art, the measurement relaxation mechanism of the connected state also introduces RLM measurement relaxation and BFD measurement relaxation and other communication link quality monitoring measurement relaxations. Among them, the RLM measurement relaxation is the measurement of the downlink wireless link quality monitoring of 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). Among them, 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. The BFD measurement relaxation is the measurement of the downlink beam quality monitoring of 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.

[0094] 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:

[0095] ​In the related art, the network configures a reference signal resource set for RRM measurement based on SSB or CSI-RS through a radio resource control signaling (RRC) message. The network configures a reference signal resource set for RLM and / or BFD measurement through an RRC message.

[0096] Both the RLM / BFD measurement relaxation and the RRM measurement relaxation can be based on a low-mobility decision criterion. In other words, both the RLM / BFD measurement relaxation and the RRM measurement relaxation can be based on the signal quality of a serving cell to determine whether relaxation can be performed. Therefore, for the RLM / BFD measurement relaxation and the 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 measurement evaluation is performed based on the reference signal configured for RRM for the RRM measurement relaxation, and the measurement evaluation is performed based on the reference signal configured for RLM / BFD for the RLM / BFD measurement relaxation, which has a large signaling overhead.

[0097] 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 decision making for both the RRM measurement relaxation and the communication link quality monitoring measurement relaxation based on the common reference signal.

[0098] In the embodiments of the present disclosure, the reference signal common to the RRM measurement relaxation and the communication link quality monitoring measurement relaxation is referred to as a common measurement reference signal.

[0099] 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 both RLM measurement relaxation and BFD measurement relaxation.

[0100] 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.

[0101] 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.

[0102] In step S12, measurement relaxation decision making is performed for both the RRM measurement relaxation and the communication link quality monitoring measurement relaxation based on the common measurement reference signal.

[0103] In the embodiments of the present disclosure, the determined common measurement reference signal can be SSB and / or CSI-RS.

[0104] 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 the terminal which supports the RRM measurement relaxation and the RLM / BFD communication link quality monitoring measurement relaxation at the same time, the measurement results (for example, Reference Signal Receiving Power (RSRP)) of the same group of reference signals are used for the judgment when the low mobility relaxation decision criterion is performed.

[0105] In the embodiments of the present disclosure, based on the common measurement reference signal shared by 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 realize the measurement relaxation decision of the RRM and the communication link quality monitoring measurement relaxation based on the common reference signal quality, and further can reduce the signaling overhead and realize the simple and efficient cooperative measurement.

[0106] The embodiments of the present disclosure will be described below based on the communication method based on the measurement relaxation mechanism based on the common measurement reference signal.

[0107] In one implementation of the embodiments of the present disclosure, the common measurement reference signal is determined based on the terminal measurement. In another implementation, the common measurement reference signal is determined based on the network indication.

[0108] Firstly, the implementation of determining the common measurement reference signal based on the terminal measurement will be described.

[0109] In the embodiments of the present disclosure, the common measurement reference signal determined based on the terminal measurement 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.

[0110] Figure 3 A flowchart of a communication method based on a measurement relaxation mechanism according to an exemplary embodiment is shown. The communication method based on the measurement relaxation mechanism 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.

[0111] 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.

[0112] 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.

[0113] 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.

[0114] 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:

[0115] 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.

[0116] 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.

[0117] 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.

[0118] 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.

[0119] 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.

[0120] 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.

[0121] 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.

[0122] In an 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 an 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.

[0123] In an 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 an 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.

[0124] 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.

[0125] 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.

[0126] 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 with the same index for the reference signal with the same type as the measurement reference signal type of RRM.

[0127] It is understood that the implementation of the above embodiments of this disclosure relies on reference signals with the same reference signal type and the same signal index among the reference signals configured for RRM measurement relaxation and communication link quality monitoring measurement relaxation. In one embodiment, if the reference signals configured for RRM measurement relaxation and communication link quality monitoring measurement relaxation do not have the same reference signal type and / or do not have the same signal index, then RRM measurement relaxation and communication link quality monitoring measurement relaxation each make measurement relaxation decisions according to the corresponding configured reference signal type.

[0128] The following describes the implementation process of determining a common measurement reference signal based on network indication in the embodiments of this disclosure.

[0129] In this embodiment of the disclosure, the network device can send indication information to the terminal to instruct the terminal to perform RRM measurement relaxation and communication link quality monitoring measurement relaxation using a common measurement reference signal. For ease of description, the indication information sent by the network device to instruct the common measurement reference signal will be referred to as the first indication information.

[0130] Figure 4 This is a flowchart illustrating a communication method based on a measurement relaxation mechanism according to an exemplary embodiment. This communication method based on the measurement relaxation mechanism can be implemented alone or in conjunction with other embodiments. Figure 4 As shown, the communication method based on the measurement relaxation mechanism is used in the terminal and includes the following steps.

[0131] In step S31, a first indication message is received from the network device. The first indication message is used to indicate a common measurement reference signal.

[0132] In this embodiment of the present disclosure, the terminal receives first indication information sent by the network device and uses the reference signal indicated by the first indication information as a common measurement reference signal.

[0133] In this embodiment of the present disclosure, the common measurement reference signal indicated by the first indication information may be a set of reference signals. The set of reference signals includes one or more reference signals.

[0134] In one implementation, the common measurement reference signal is determined based on the intersection of the set of reference signals used for configured RRM measurement relaxation and the set of reference signals used for configured communication link quality monitoring measurement relaxation. For example, the network device determines the common measurement reference signal as the intersection of the set of reference signals used for RRM measurement relaxation and the set of reference signals used for configured communication link quality monitoring measurement relaxation. In another implementation, the common measurement reference signal is a custom set of reference signals. For example, the network device autonomously configures a set of reference signals as the common measurement reference signal.

[0135] 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.

[0136] 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.

[0137] 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.

[0138] 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.

[0139] 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.

[0140] First, the RLM measurement relaxation and the RRM measurement relaxation are described.

[0141] Scheme 1: Terminal measurement

[0142] 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 common SSB index as the basis for judging whether the terminal enters RRM and RLM low-mobility relaxation;

[0143] 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 common CSI-RS index as the basis for judging whether the terminal enters RRM and RLM low-mobility relaxation;

[0144] 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 with common index, RLM and RRM use the measurement result of common index for relaxation judgment;

[0145] 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;

[0146] 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).

[0147] Scheme 2: Network indication

[0148] 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:

[0149] Among them, the common-RS can be the intersection of RLM-RS and RRM-RS, or a set of reference signals configured by the network autonomously;

[0150] 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;

[0151] 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 5As shown, 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 by the bit bitmap "11111000" as {0, 1, 2}. The network device configures the reference signal for RLM measurement as {0, 1, 2}.

[0152] In one scheme, the terminal performs measurement based on the common index, that is, {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 scheme, when the network issues the low-mobility criterion parameter, it also issues the reference signal set {0, 1, 2} for measurement, indicating the reference signal for the terminal to perform relevant measurement.

[0153] Secondly, the BFD measurement relaxation and the RRM measurement relaxation are described.

[0154] Scheme 1: Terminal measurement

[0155] 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.

[0156] 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.

[0157] 3. If BFD is based on both SSB and CSI-RS as the reference signal, in this case, according to the measurement reference signal type of RRM, for the same type of reference signal with common index, BFD and RRM use the measurement result of the common index for relaxation determination.

[0158] 4. If RRM and BFD are based on completely different reference signal types, they are judged according to the corresponding reference signal type whether to relax or not.

[0159] For this scheme, 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).

[0160] Scheme 2: Network indication

[0161] The network indicates the reference signal used by the terminal to judge the low mobility criterion, denoted as common-RS, which is used for both RRM and BFD measurement relaxation judgment:

[0162] The common-RS can be the intersection of BFD-RS and RRM-RS, or a set of reference signals autonomously configured by the network.

[0163] The common-RS indication can be delivered to the terminal through dedicated RRC signaling, or configured to the terminal along with the parameters of the low mobility relaxation criterion.

[0164] The above method for communicating based on measurement relaxation provided by the embodiments of the present disclosure can simultaneously judge the low mobility criterion of RRM and RLM, or the low mobility criterion of RRM and BFD, based on the same set of reference signal quality, to achieve more efficient and concise cooperative measurement.

[0165] Based on the same concept, the embodiments of the present disclosure also provide a method for communicating based on measurement relaxation applied to a network device.

[0166] Figure 6 is a flowchart of a communication method based on measurement relaxation according to an exemplary embodiment. The communication method based on measurement relaxation can be implemented alone or in combination with other embodiments. As shown in Figure 6 The communication method based on measurement relaxation is used in a network device, including the following steps.

[0167] In step S41, a common measurement reference signal is determined, which is a reference signal common to RRM measurement relaxation and communication link quality monitoring measurement relaxation.

[0168] In step S42, first indication information is sent, which is used to indicate the common measurement reference signal.

[0169] The common measurement reference signal indicated by the first indication information in the embodiments of the present disclosure can be a reference signal set. The reference signal set includes one or more reference signals.

[0170] In one embodiment, the common measurement reference signal is determined based on an intersection between a set of reference signals used for relaxed RRM measurement configured by the network device and a set of reference signals used for relaxed communication link quality monitoring measurement configured by the network device. For example, the network device determines the intersection between the set of reference signals used for relaxed RRM measurement and the set of reference signals used for relaxed communication link quality monitoring measurement as the common measurement reference signal. In another embodiment, the common measurement reference signal is a set of self-defined reference signals. For example, the network device autonomously configures a set of reference signals as the common measurement reference signal.

[0171] In one aspect of the embodiments of the present disclosure, the first indication information can be carried in a dedicated RRC, and the network device sends the first indication information based on the dedicated RRC signaling. In another aspect, the first indication information can also be configured to the terminal together with the low-mobility relaxation criterion configuration parameter, and the network device sends the first indication information based on the low-mobility relaxation criterion configuration parameter.

[0172] Further, in the embodiments of the present disclosure, the network device sends the second indication information, and uses the common measurement reference signal to make a measurement relaxation decision on the RRM measurement relaxation and the communication link quality monitoring measurement relaxation. 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 make a low-mobility measurement relaxation decision on the RRM and BFD.

This can realize a measurement relaxation decision on the RRM and the communication link quality monitoring measurement relaxation based on the quality of the common reference signal, and further reduce signaling overhead and realize simple and efficient cooperative measurement.
