[0051] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below. The following relevant technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the protection scope of the embodiments of the present application.

[0052] The current demand for speed, latency, high-speed mobility, and energy efficiency, coupled with the increasing diversity and complexity of future services, is driving the development and evolution of 5G technology. The main application scenarios for 5G are: enhanced mobile broadband (eMBB), ultra-reliable low-latency communications (URLLC), and massive machine-type communications (mMTC).

[0053] NR can also be deployed independently. In order to reduce air interface signaling and quickly restore wireless connections and data services in the 5G network environment, a new RRC (Radio Resource Control) state is defined, namely the RRC_INACTIVE state (RRC inactive). This state is different from the RRC_IDLE (RRC idle state) and RRC_CONNECTED state (RRC connected state). Specifically, the RRC states include:

[0054] RRC_IDLE: Mobility is based on UE cell reselection. Paging is initiated by the CN (Core Network), and the paging area is configured by the CN. There is no UE AS (Access Stratum) context on the base station side. No RRC connection exists.

[0055] RRC_CONNECTED: An RRC connection exists, and a UE AS context exists between the eNodeB and the UE. The network knows the UE's location at the cell level. Mobility is controlled by the network. Unicast data can be transmitted between the UE and the eNodeB.

[0056] RRC_INACTIVE: Mobility is UE-based cell selection and reselection. There is a connection between CN and NR. The UE AS context exists on a certain base station. Paging is triggered by the RAN (Random Access Network). The RAN-based paging area is managed by the RAN. The network side knows the UE location based on the RAN paging area level.

[0057] RedCap (reduced capability) terminal application scenarios:

[0058] In addition to application scenarios such as eMBB and URLLC, IoT use cases such as industrial wireless sensors, video surveillance, and wearable devices have put forward new requirements for 5G terminals, such as reduced complexity and cost, smaller size, and lower energy consumption. To this end, low-capability devices are introduced into the NR system. Currently, low-capability devices mainly fall into three scenarios:

[0059] (1) Industrial Wireless Sensors. Compared with URLLC, industrial wireless sensors have relatively low latency and reliability requirements. At the same time, the cost and power consumption of the equipment are lower than those of URLLC and eMBB. The main requirements and features of this terminal type include: communication reliability of 99.99%, end-to-end latency of less than 100ms (milliseconds), reference data rate of less than 2Mbps (Megabits Per Second), mainly uplink services, stationary equipment, and battery life of up to several years. For sensors used for safety-related purposes, the latency requirement is even lower, at 5 to 10ms.

[0060] (2) Video surveillance, mainly including video surveillance scenarios such as smart cities and industrial factories. Data collection and processing in smart cities can facilitate more effective monitoring and control of urban resources and provide more effective services to urban residents. Video surveillance is mainly based on uplink services. Other major requirements include: a reference rate of 2 to 4 Mbps for standard resolution video, a latency of less than 500ms, and a communication reliability of 99% to 99.9%. The rate requirement for high-definition video is 7.5 to 25 Mbps.

[0061] (3) Wearables, including smart watches, smart bracelets, electronic health devices, and some medical monitoring devices. These devices have the following common characteristics: small size, and key performance requirements include: downlink and uplink reference rates of 5-50 Mbps and 2-5 Mbps respectively; downlink and uplink peak rates of 150 Mbps and 50 Mbps respectively; and battery life of several days or even 1-2 weeks.

[0062] RRM measurement of R15 non-connected UE:

[0063] A terminal in a non-connected state needs to perform RRM measurements on the serving cell and other neighboring cells based on network configuration to support mobility operations, such as cell reselection.

[0064] The UE in the non-connected state continuously performs measurements on the serving cell.

[0065] In NR Rel-15, for the sake of terminal energy saving, when the UE has a good quality channel in the serving cell, the UE may not start RRM measurements for the same frequency point and the same or lower priority inter-frequency / inter-technology frequency points, and may perform relaxed RRM measurements for high priority inter-frequency / inter-technology frequency points. Specifically:

[0066] For the same frequency point, if the Srxlev (signal received power in cell search) measured by the serving cell is higher than the threshold SIntraSearchP And Squal (signal reception quality in cell search) is higher than the threshold S IntraSearchQ , the UE can turn off the measurement of all co-frequency neighboring cells.

[0067] For NR inter-frequency points or inter-technology points with low priority or equal priority, if the Srxlev measured by the serving cell is higher than the threshold S nonIntraSearchP And Squal is higher than the threshold S nonIntraSearchQ , the UE can turn off the measurement of all NR inter-frequency points or inter-technology points of low priority or equal priority.

[0068] For high-priority NR inter-frequency points or inter-technology frequency points, if the Srxlev measured by the serving cell is higher than the threshold S nonIntraSearchP And Squal is higher than the threshold S nonIntraSearchQ , then the UE can perform relaxed measurements on high-priority NR inter-frequency points or inter-technology frequency points. At this time, for each high-priority frequency point, the measurement interval is relaxed to Thigher_priority_search = (60*N layers )s (seconds), where N layers The number of high-priority frequencies for network broadcasting.

[0069] Among them, the parameter S IntraSearchP 、S IntraSearchQ 、S nonIntraSearchP and S nonIntraSearchQ It is configured by the network through SIB (System Information Block) 2.

[0070] In NR, the cell measurement requirements include T detect 、T measure and T evaluate , which are the time used for cell detection, cell measurement and cell evaluation respectively. Usually these conditions are related to the DRX (Discontinuous Reception) cycle of the terminal.

[0071] R16NR RRM measurement relaxation for non-connected UEs:

[0072] R16 introduces a neighbor cell measurement relaxation mechanism for non-connected UEs to further meet the terminal power saving needs.

[0073] To support relaxed neighbor cell measurements, the low mobility criterion and the not-at-cell-edge criterion are introduced. Both criterions are based on the UE's measurements on the serving cell. The standard defines the low mobility criterion and the not-at-cell-edge criterion as follows:

[0074] (1) “Low mobility” criterion:

[0075] This criterion can also be called the stationary criterion. For this criterion, the network will configure the evaluation time T of RSRP (Reference Signal Receiving Power) changes. SearchDeltaP and RSRP change threshold S SearchDeltaP When a period of time is T SearchDeltaP The RSRP change of the UE in the serving cell is less than S SearchDeltaP When , the UE is considered to meet the "low mobility" criterion. That is: in a period of time T SearchDeltaP In, satisfy:

[0076] (SrxlevRef–Srxlev) SearchDeltaP (1)

[0077] Wherein, Srxlev is the current Srxlev measurement value of the serving cell, and SrxlevRef is the reference Srxlev value of the serving cell.

[0078] When the UE selects or reselects to a new cell, or if (Srxlev-SrxlevRef)>0, or if the UE does not SearchDeltaP If the formula (1) is satisfied within the time, then:

[0079] The UE sets SrxlevRef to the current Srxlev measurement value of the serving cell;

[0080] After completing cell selection / reselection, the UE needs to wait for at least a period of time T SearchDeltaP Normal RRM measurements are performed within the

[0081] (2) “not-at-cell-edge” principle:

[0082] For this criterion, the network will configure an RSRP threshold S SearchThresholdP In addition, you can also configure an RSRQ (Reference Signal Receiving Quality) threshold S​SearchThresholdQ When the RSRP of the UE on the serving cell is greater than the RSRP threshold, and when the network configures the RSRQ threshold, the RSRQ of the UE on the serving cell is greater than the RSRQ threshold, the UE is considered to meet the "not-at-cell-edge" criterion.

[0083] The network notifies the UE via system broadcast whether the RRM measurement relaxation function can be enabled. When the RRM measurement relaxation function is enabled, the network needs to configure at least one RRM measurement relaxation judgment criterion. Depending on the configuration, the following four situations may exist:

[0084] Case 1: The network is configured with only the low mobility criterion. When the UE meets the low mobility criterion, the UE starts the relaxed RRM measurement for the neighboring cells.

[0085] Case 2: The network is configured with only the not-at-cell-edge criterion. When the UE meets the not-at-cell-edge criterion, the UE performs relaxed RRM measurements on neighboring cells.

[0086] Case 3: The network is configured with both the low mobility criterion and the not-at-cell-edge criterion, and the network does not configure the parameter combineRelaxedMeasCondition. In this case, when the UE meets at least one of the two criteria, the UE starts relaxed RRM measurements for the neighboring cells.

[0087] Case 4: The network is configured with both the low mobility criterion and the not-at-cell-edge criterion, and the network is configured with the parameter combineRelaxedMeasCondition. At this time, when the UE meets both criteria, the UE starts relaxed RRM measurements for neighboring cells.

[0088] For non-connected UEs, there are two RRM measurement relaxation methods:

[0089] Method 1: When the UE only meets the low mobility criterion or the not-at-cell-edge criterion, for intra-frequency measurement, NR inter-frequency measurement, and inter-technology inter-frequency measurement, the measurement interval is relaxed to three times the normal measurement interval.

[0090] Method 2: When the UE meets both the low mobility criterion and the not-at-cell-edge criterion, the measurement interval can be relaxed to 1 hour for intra-frequency measurement, NR inter-frequency measurement, and inter-technology inter-frequency measurement.

[0091] In addition, for high priority frequencies, the parameter highPriorityMeasRelax is introduced. This parameter is used to indicate whether the network allows the UE to relax the measurement interval at the high priority frequency to a value exceeding Thigher_priority_search (except when the UE meets both the low mobility criterion and the not-at-cell-edge criterion). In other words, the parameter highPriorityMeasRelax is only used to control the situation where the network is only configured with the low mobility criterion and the UE meets the low mobility criterion, and the UE's measurement results in the serving cell meet the conditions that Srxlev is greater than SnonIntraSearchP and Squal is greater than S nonIntraSearchQ In this case, if the network configures the parameter highPriorityMeasRelax, the UE's measurement interval for high-priority frequencies can be relaxed to K2*Thigher_priority_search, where K2 is 60; if the network does not configure the parameter highPriorityMeasRelax, the UE's measurement interval for high-priority frequencies is Thigher_priority_search.

[0092] In addition to the aforementioned low mobility and not-at-cell-edge criteria, RRM measurement relaxations can be added for RedCap terminals, including measurement relaxations for the low mobility and not-at-cell-edge criteria. Regarding RedCap terminals, NR currently supports UE power classes of 23dBm and 26dBm; related technologies have also proposed introducing lower UE power classes to further save terminal power consumption.

[0093] In the SL scenario, the UE needs to perform RRM measurements to select an appropriate serving relay terminal (Relay UE) or network node, etc. In this scenario, it is necessary to consider how to save terminal power consumption.

[0094] FIG2 is a schematic flow chart of a measurement method 200 according to an embodiment of the present application. The method may optionally be applied to the system shown in FIG1 , but is not limited thereto. The method includes at least part of the following contents.

[0095] S210, when the measurement information of the service link meets the first criterion, the first terminal performs relevant processing for the measurement of the adjacent link; wherein the service link is the link between the first terminal and the service device; the adjacent link is the link between the first terminal and the adjacent device; the service device and / or the adjacent device is a relay terminal.

[0096] Illustratively, the service device in the embodiment of the present application may include a network device of a service cell where the first terminal is located or a service relay terminal of the first terminal.

[0097] The serving relay terminal may be a relay terminal between the first terminal and the second terminal, that is, the serving relay terminal may be used for terminal-to-terminal relay (UE-to-UE relay). Alternatively, the serving relay terminal may be a relay terminal between the first terminal and a network device of a serving cell where the first terminal is located, that is, the serving relay terminal may be used for terminal-to-network relay (UE-to-NW relay).

[0098] Exemplarily, the adjacent device in the embodiment of the present application may include a network device of a neighboring cell of the serving cell where the first terminal is located, or a relay terminal corresponding to the first terminal. The relay terminal corresponding to the first terminal may be another terminal that can be used to relay for the first terminal. For example, the relay terminal may be another relay terminal other than the serving relay terminal between the first terminal and the network device of the serving cell, or another relay terminal other than the serving relay terminal between the first terminal and the second terminal, or a relay terminal between the first terminal and the network device of the neighboring cell.

[0099] In this embodiment of the present application, at least one of the serving device and the adjacent device is a relay terminal. That is, the above method can be applied to sidelink relay scenarios. It is understood that the first terminal can be a remote terminal (Remote UE) in scenarios such as terminal-to-terminal relay or terminal-to-network relay.

[0100] In an exemplary scenario, the serving device is a serving relay terminal between the first terminal and the second terminal, and the neighboring device is another relay terminal between the first terminal and the second terminal.

[0101] In another exemplary scenario, the serving device is a serving relay terminal between the first terminal and a network device of a serving cell where the first terminal is located, and the neighboring device is a network device of a cell adjacent to the serving cell where the first terminal is located.

[0102] In another exemplary scenario, the serving device is the network device of the serving cell where the first terminal is located, and the neighboring device is the relay terminal corresponding to the first terminal. Optionally, the relay terminal can be a relay terminal between the first terminal and the network device of the serving cell where the first terminal is located, or a relay terminal between the first terminal and the network device of a cell adjacent to the serving cell where the first terminal is located.

[0103] It should be noted that in the embodiments of the present application, the serving device and the adjacent device may be different devices or the same device. For example, the serving device and the adjacent device may be the same device, which establishes two logically different links with the first terminal, one of which is a serving link for the first terminal.

[0104] According to the above method, in the sidelink relay scenario, when the measurement information of the service link meets the first criterion, predetermined processing is performed on the measurement of the adjacent link, so that the measurement of the adjacent link can be adjusted in a timely manner, which is conducive to saving terminal power consumption.

[0105] For example, the measurement information in the embodiments of the present application may include channel quality measurement results. In some implementations, it may include RSRP and / or RSRQ.

[0106] For example, the first criterion may include any criterion for determining whether the measurement information of the service link meets the requirements. In practical applications, the first criterion may include parameters related to the measurement information, so as to use the parameters to determine whether the channel quality of the service link meets the requirements.

[0107] Exemplarily, the parameters of the first criterion may include a threshold value. Optionally, the threshold value may include an RSRP threshold value and / or an RSRQ threshold value. For example, when the RSRP of the serving link is greater than the RSRP threshold value, the measurement information of the serving link is determined to meet the first criterion. For another example, when the RSRP of the serving link is greater than the RSRP threshold value and the RSRQ of the serving link is greater than the RSRQ threshold value, the measurement information of the serving link is determined to meet the first criterion.

[0108] Optionally, the first criterion may include at least one of a non-cell edge criterion, a stationary criterion, and a low mobility criterion. Specific configuration methods may refer to the aforementioned related technologies and will not be described in detail here.

[0109] Exemplarily, in the embodiment of the present application, the measurement-related processing performed on the adjacent link may include a preset processing method related to adjusting the measurement configuration.

[0110] Optionally, performing relevant processing on the measurement of the adjacent link may include: shutting down the measurement of the adjacent link.

[0111] Optionally, performing related processing on the measurement of the adjacent link may include relaxing the measurement of the adjacent link. Exemplarily, relaxing the measurement of the adjacent link may include increasing the measurement interval for the adjacent link, or using a preset measurement interval for relaxing the measurement. For example, the measurement interval may be adjusted to M times the normal measurement interval, where M is greater than 1. For another example, the measurement interval may be adjusted to 1 hour, 2 hours, or the like.

[0112] Optionally, performing related processing on the measurement of the adjacent link may include sending first reporting information, where the first reporting information is used to determine whether to adjust the measurement of the adjacent link. Specifically, the first reporting information may be sent to a serving device to report to the serving device that the measurement information of the serving link meets a first criterion. In practical applications, the serving device may be a network device of a serving cell where the first terminal is located.

[0113] Accordingly, in an embodiment of the present application, the measurement method may include: the service device receives first reporting information from the first terminal, and determines whether to adjust the measurement of the adjacent link by the first terminal based on the first reporting information.

[0114] Optionally, when the measurement information of the serving link does not meet the first criterion, the first terminal may not perform the above-mentioned measurement-related processing. For example, the first terminal may continue to measure the adjacent link based on the normal measurement interval.

[0115] In the embodiments of the present application, multiple methods for determining the first criterion may be provided.

[0116] Optionally, the first criterion may be pre-configured, configured by the network device, or configured by the service device.

[0117] Optionally, the first criterion may be determined based on received first indication information. Specifically, before step S210, the measurement method may further include: the first terminal receiving first indication information; wherein the first indication information is used to determine the first criterion. The first indication information may come from a serving device of the first terminal, such as a network device of a serving cell of the first terminal or a serving relay terminal of the first terminal.

[0118] Accordingly, the present application also provides a measurement method. FIG3 shows a schematic flow chart of a measurement method 300 according to another embodiment of the present application. As shown in FIG3 , the method may include:

[0119] S310, the serving device sends first indication information to the first terminal; wherein the first indication information is used by the first terminal to determine a first criterion, so as to perform relevant processing on the measurement of the adjacent link when the measurement information of the serving link meets the first criterion.

[0120] The service link is a link between the first terminal and the service device; the adjacent link is a link between the first terminal and the adjacent device; the service device and / or the adjacent device is a relay terminal.

[0121] Optionally, the first indication information is carried by at least one of the following: Uu interface (interface between the UE and the network device) signaling, sidelink signaling, sidelink RRC signaling, and a sidelink discovery message. The sidelink signaling is, for example, PC5-S signaling. The sidelink RRC signaling is, for example, PC5-RRC signaling. The sidelink discovery message is, for example, a ProSe Direct Discovery (Proximity Service Direct Discovery) message.

[0122] In some examples, the first indication information may be used to indicate the first criterion. That is, the first criterion may be determined by the service device and indicated by the service device by sending the first indication information.

[0123] Exemplarily, the first indication information may include parameters in the first criterion, for example, the first indication information includes the RSRP threshold value and / or the RSRP threshold value.

[0124] Optionally, the first criterion is preconfigured or configured by the network device. For example, when the serving device is a serving relay terminal, the serving device may determine the first criterion based on preconfigured information or network configuration information. When the serving device is a network device of a serving cell where the first terminal is located, the serving device may determine the first criterion based on preconfigured information.

[0125] Optionally, the first criterion is determined based on a transmit power level of the serving device. Exemplarily, before the serving device sends the first indication information to the first terminal, the measurement method may further include: the serving device determining the first criterion based on the transmit power level of the serving device.

[0126] Optionally, the serving device determines the first criterion based on the transmission power level of the serving device, which may include: the serving device determines the first criterion based on the transmission power level of the serving device and at least one criterion.

[0127] Exemplarily, the service device may predetermine a correspondence between at least one transmit power level and at least one criterion, and then determine the first criterion based on the correspondence and the transmit power level of the service device.

[0128] Optionally, the serving device determines the first criterion based on the transmit power level of the serving device and at least one criterion, including: the serving device selects the first criterion from the at least one criterion based on the transmit power level of the serving device.

[0129] Specifically, the service device may select a first criterion corresponding to the transmission power level of the service device from the at least one criterion based on the correspondence between the at least one transmission power and the at least one criterion.

[0130] Optionally, the service device determines the first criterion based on the transmission power level of the service device and at least one criterion, including: the service device processes a second criterion of the at least one criterion based on the transmission power level of the service device to obtain the first criterion.

[0131] Specifically, if the at least one criterion contains only a single criterion, that is, the at least one criterion includes only the second criterion, the service device may process the second criterion based on the transmit power level of the service device to obtain the first criterion. If the at least one criterion contains multiple criterions, the service device may select the second criterion from the multiple criteria based on the transmit power level of the service device, and then process the second criterion based on the transmit power level of the service device to obtain the first criterion.

[0132] For example, at least one criterion includes a second criterion corresponding to 20dBm. If the transmission power level of the service device is 23dBm, the difference or ratio between 20dBm and 23dBm is calculated with the threshold value in the second criterion to obtain the target threshold value, and the first criterion is determined based on the target threshold value.

[0133] Optionally, the at least one criterion is preconfigured or configured by the network device. For example, if the serving device is a serving relay terminal between the first terminal and the network device of the serving cell, the serving relay terminal may determine the at least one criterion based on preconfigured information or the configuration of the network device of the serving cell. For another example, if the serving device is the network device of the serving cell, the network device may determine the at least one criterion based on preconfigured information.

[0134] Optionally, the parameters in the at least one criterion include a threshold value, the threshold value is related to measurement information, and the threshold value is pre-configured or configured by the network device. The measurement information may include RSRP and / or RSRQ.

[0135] In the various optional manners described above, the correspondence between at least one transmit power and at least one criterion may be determined in an explicit or implicit manner.

[0136] As an example of an explicit manner, the measurement method in the embodiment of the present application may further include: the service device receives third indication information, wherein the third indication information is used to indicate the correspondence between at least one transmission power level and at least one criterion.

[0137] The serving device may be a serving relay terminal, and the third indication information may be sent by a network device of a serving cell.

[0138] As an example of an implicit method, the measurement method in the embodiment of the present application may further include: the service device determines the correspondence between at least one transmission power level and at least one criterion based on a threshold value in at least one criterion.

[0139] Optionally, the service device determines the correspondence between at least one transmission power level and at least one criterion based on the threshold value in at least one criterion, including: the service device determines the correspondence between at least one transmission power level and at least one criterion based on the size order of the threshold values ​​in at least one criterion and the size order of at least one transmission power level.

[0140] For example, there is a one-to-one correspondence between at least one transmit power level and at least one criterion. The at least one criterion is sorted from largest to smallest according to the corresponding RSRP / RSRQ threshold value, and the at least one transmit power level is sorted from largest to smallest. Then, the nth transmit power level corresponds to the nth criterion, where n is an integer greater than or equal to 1, and n is less than or equal to the number of criteria.

[0141] According to the above multiple examples, the service device can directly indicate the first criterion in the first indication information, so that the first terminal can determine the first criterion based on the first indication information, and then after measuring the channel quality of the service link, determine whether to perform relevant processing on the adjacent link based on whether the measurement information meets the first criterion.

[0142] In other examples, the first indication information may be used to indicate other information used to determine the first criterion, so that the first terminal determines the first criterion based on the information. For example, the first indication information may be used to indicate the transmit power level of the serving device, so that the first terminal determines the first criterion based on the transmit power level of the serving device.

[0143] Optionally, after receiving the first indication information, the measurement method of the embodiment of the present application may further include: the first terminal determining a first criterion based on a transmit power level of the serving device and at least one criterion.

[0144] Exemplarily, the first terminal may predetermine a correspondence between at least one transmit power level and at least one criterion, and then determine the first criterion based on the correspondence and the transmit power level of the serving device.

[0145] Optionally, the first terminal determines the first criterion based on the transmit power level of the serving device and at least one criterion, including: the first terminal selects the first criterion from the at least one criterion based on the transmit power level of the serving device.

[0146] Specifically, the first terminal may select a first criterion corresponding to the transmit power level of the serving device from the at least one criterion based on the correspondence between the at least one transmit power and the at least one criterion.

[0147] Optionally, the first terminal determines the first criterion based on the transmit power level of the serving device and at least one criterion, including: the first terminal processes a second criterion of the at least one criterion based on the transmit power level of the serving device to obtain the first criterion.

[0148] Specifically, if the number of criteria in at least one criterion is single, that is, the at least one criterion includes only the second criterion, the first terminal may process the second criterion based on the transmit power level to obtain the first criterion. If the number of criteria in at least one criterion is multiple, the first terminal may select the second criterion from the multiple criteria based on the transmit power level of the serving device, and then process the second criterion based on the transmit power level of the serving device to obtain the first criterion.

[0149] Optionally, the at least one criterion is preconfigured, configured by a network device, or configured by a serving device. For example, if the serving device is a serving relay terminal of the first terminal, the first terminal may determine the at least one criterion based on preconfigured information, the configuration of a network device in the serving cell, or the configuration of the serving relay terminal. For another example, if the serving device is a network device in the serving cell of the first terminal, the first terminal may determine the at least one criterion based on preconfigured information or the configuration of the network device.

[0150] Optionally, the parameters in at least one criterion include a threshold value, the threshold value is related to measurement information, and the threshold value is pre-configured, or configured by the network device, or configured by the service device. The measurement information may include RSRP and / or RSRQ.

[0151] In the various optional manners described above, the correspondence between at least one transmit power and at least one criterion may be determined in an explicit or implicit manner.

[0152] As an example of an explicit method, the measurement method may further include: the first terminal receiving second indication information, wherein the second indication information is used to indicate a correspondence between at least one transmit power level and at least one criterion. The second indication information may be sent by a service device or a network device.

[0153] As an example of an implicit manner, the measurement method may further include: the first terminal determining a correspondence between at least one transmit power level and at least one criterion based on a threshold value in at least one criterion.

[0154] Optionally, the first terminal determines the correspondence between at least one transmission power level and at least one criterion based on the threshold value in at least one criterion, including: the first terminal determines the correspondence between at least one transmission power level and at least one criterion based on the size order of the threshold values ​​in at least one criterion and the size order of at least one transmission power level.

[0155] According to the above multiple examples, the service device can indicate the transmission power level of the service device in the first indication information to indirectly indicate the first criterion, so that the first terminal can determine the first criterion, and then after measuring the channel quality of the service link, determine whether to perform relevant processing on the adjacent link based on whether the measurement information meets the first criterion.

[0156] Several application examples are provided below to illustrate the above solutions.

[0157] Application Example 1

[0158] This application example uses the first terminal as a remote terminal (Remote UE), the serving device as a serving relay terminal (Relay UE) between the first terminal and the second terminal, and the adjacent device as another relay terminal between the first terminal and the second terminal as an example to illustrate the aforementioned solution. The specific implementation process includes:

[0159] 1. The remote terminal or serving relay terminal receives network-configured or pre-configured RRM measurement relaxation related information for the remote terminal, including:

[0160] a) At least one criterion. The at least one criterion includes at least one of a non-cell edge criterion, a stationary criterion, and a low mobility criterion. Each criterion in the at least one criterion includes an RSRP threshold value and, optionally, an RSRQ threshold.

[0161] b) A correspondence between at least one criterion and at least one UE transmit power level, where the correspondence is determined by explicit notification or implicitly.

[0162] The explicit notification method may be used in the case where one criterion corresponds to at least one UE transmit power level.

[0163] The implicit determination method is applicable to the case where there is a one-to-one correspondence between criteria and UE transmit power levels. Specifically, the correspondence between N criteria and N UE transmit power levels can be determined by sorting the N criteria in descending order according to the corresponding RSRP / RSRQ thresholds, and sorting the N UE transmit power levels in descending order according to power, so that the nth criterion corresponds to the nth UE transmit power level; where N is an integer greater than or equal to 1, and n is an integer greater than or equal to 1 and less than or equal to N.

[0164] 2. Optionally, the relay terminal determines a first criterion corresponding to the service range of the relay terminal based on at least one criterion and the above-mentioned correspondence, and in combination with its own transmit power level. The relay terminal sends first indication information to the remote UE to indicate the first criterion. For example, the first indication information can be carried by PC5-S signaling, PC5-RRC signaling, ProSe Direct Discovery, etc.

[0165] Alternatively, optionally, the remote terminal determines a first criterion corresponding to the service range of the relay terminal based on at least one criterion and a correspondence between the at least one criterion and at least one UE transmit power level, and in combination with the transmit power level of the relay terminal. The transmit power level is indicated by the relay terminal sending first indication information to the remote UE. For example, the first indication information may be carried by PC5-S signaling, PC5-RRC signaling, ProSe Direct Discovery, or the like.

[0166] 3. As shown in Figure 4, the following steps are included:

[0167] S401: The Remote UE determines relevant configurations, including the above RRM measurement relaxation configuration.

[0168] S402: Based on the channel quality measurement result of the serving relay terminal (taking Relay 1 as an example), it is determined that the first criterion is met.

[0169] S403: The Remote UE performs processing related to measurement relaxation, including:

[0170] Disable RRM measurements for adjacent relay terminals (for example, Relay 2); or

[0171] Relaxed RRM measurement is initiated for adjacent relay terminals, such as increasing the measurement interval to M times (M>1) of normal measurement, or using a fixed measurement interval such as 1 hour.

[0172] Application Example 2

[0173] This application example uses the first terminal as a remote terminal (Remote UE), the serving device as a relay terminal (Relay UE) serving the first terminal, and the adjacent device as a device in an adjacent cell as an example to illustrate the above-mentioned solution. The specific implementation process includes:

[0174] 1. The remote terminal or relay terminal receives network-configured or pre-configured RRM measurement relaxation information for the remote terminal, including:

[0175] a) At least one criterion. The at least one criterion includes at least one of a non-cell edge criterion, a stationary criterion, and a low mobility criterion. Each criterion in the at least one criterion includes an RSRP threshold value and, optionally, an RSRQ threshold.

[0176] b) A correspondence between at least one criterion and at least one UE transmit power level, where the correspondence is determined by explicit notification or implicitly.

[0177] The explicit notification method may be used in the case where one criterion corresponds to at least one UE transmit power level.

[0178] The implicit determination method is applicable to the case where there is a one-to-one correspondence between criteria and UE transmit power levels. Specifically, the correspondence between N criteria and N UE transmit power levels can be determined by sorting the N criteria in descending order according to the corresponding RSRP / RSRQ thresholds, and sorting the N UE transmit power levels in descending order of power, then the nth set of criteria corresponds to the nth UE transmit power level; where N is an integer greater than or equal to 1, and n is an integer greater than or equal to 1 and less than or equal to N.

[0179] 2. Optionally, the relay terminal determines a first criterion corresponding to the service range of the relay terminal based on at least one criterion and the above-mentioned correspondence, and in combination with its own transmit power level. The relay terminal sends first indication information to the remote UE to indicate the first criterion. For example, the first indication information can be carried by PC5-S signaling, PC5-RRC signaling, ProSe Direct Discovery, etc.

[0180] Alternatively, optionally, the remote terminal determines a first criterion corresponding to the service range of the relay terminal based on at least one criterion and a correspondence between the at least one criterion and at least one UE transmit power level, and in combination with the transmit power level of the relay terminal. The transmit power level is indicated by the relay terminal sending first indication information to the remote UE. For example, the first indication information may be carried by PC5-S signaling, PC5-RRC signaling, ProSe Direct Discovery, or the like.

[0181] 3. As shown in Figure 5, the following steps are included:

[0182] S501: The remote terminal determines relevant configurations, including the above RRM measurement relaxation configuration.

[0183] S502: Determine that a first criterion is met based on a channel quality measurement result of a serving relay terminal (eg, relay 1).

[0184] S503: The remote terminal performs processing related to measurement relaxation, including:

[0185] Disable RRM measurements for neighboring cells (e.g., for the base station gNB of the neighboring cell); or

[0186] Relaxed RRM measurements are initiated for neighboring cells, such as increasing the measurement interval to M times (M>1) of normal measurements, or using a fixed measurement interval such as 1 hour.

[0187] Application Example 3

[0188] This application example uses the first terminal as a remote terminal, the serving device as a network device (or network node) in the serving cell where the first terminal is located, and the adjacent device as an adjacent relay UE (for example, a relay UE in the serving cell or a relay UE in an adjacent cell) as an example to illustrate the aforementioned solution. The specific implementation process includes:

[0189] 1. The remote terminal or relay terminal receives network-configured or pre-configured RRM measurement relaxation information for the remote terminal, including:

[0190] At least one criterion. The at least one criterion includes at least one of a non-cell edge criterion, a stationary criterion, and a low mobility criterion. Each criterion in the at least one criterion includes an RSRP threshold value and, optionally, an RSRQ threshold.

[0191] 2. As shown in Figure 6, the following steps are included:

[0192] S601: The remote terminal determines relevant configurations, including the above RRM measurement relaxation configuration.

[0193] S602: The remote terminal determines that a first criterion is satisfied based on a channel quality measurement result of a serving cell.

[0194] S603: The remote terminal performs processing related to measurement relaxation, including:

[0195] Disable RRM measurements for adjacent relay terminals (e.g., Relay2); or

[0196] Initiate relaxed RRM measurements for adjacent relay terminals, such as increasing the measurement interval to M times the normal measurement (M>1), or using a fixed measurement interval such as 1 hour; or,

[0197] The reporting information is sent to a network node so that the network node determines whether to adjust the measurement of the adjacent relay terminal.

[0198] As can be seen, the embodiments of the present application provide a method for relaxing terminal RRM measurements in a sidelink relay scenario. Using this method, low-mobility / stationary UEs or UEs in the center of the service coverage area can perform relaxed RRM measurements, which can meet the needs of terminal mobility management while taking into account the needs of terminal power saving.
