Description

Technical Field

[0001] This application belongs to the technical field of communications, and specifically relates to a measurement relaxation method, apparatus, terminal, and network-side device.

Background Art

[0002] In a conventional mobile communication system, in order to save power, a terminal such as a Narrow Band Internet of Things (NB-IoT) terminal can relax the measurement of adjacent cells of the same or different frequencies under the condition that the measurement value of the serving cell satisfies the measurement relaxation determination criterion. When it is determined that the measurement relaxation determination criterion condition is satisfied, generally, it is necessary to determine whether the terminal is in a low mobility state and / or whether it is at the cell center.

[0003] To determine whether a terminal in the idle state is in a low mobility state, it is only necessary to determine the low mobility state and / or the cell center based on the current resident cell. However, in other scenarios that support Carrier Aggregation (CA) or Dual Connectivity (DC), the terminal may be configured to be simultaneously connected to multiple serving cells, and the multiple serving cells are distributed in one or more cell groups, and the terminal may be in a connected state. Therefore, for those skilled in the art, in the connected state scenario, it is urgent to realize a solution for determining whether the terminal performs measurement relaxation.

[0022] In the following, with reference to the drawings, the measurement relaxation method provided in the embodiments of this application will be described in detail by means of several embodiments and their application scenarios.

[0023] Figure 2 is a schematic flowchart (Part 1) of the measurement relaxation method provided in the embodiments of this application. As shown in Figure 2, the measurement relaxation method provided in this embodiment includes the following steps 101 and 102.

[0024] In step 101, based on the measurement results of each cell group among at least one cell group, the low-mobility state judgment criterion, and the cell center judgment criterion, the terminal determines the low-mobility state judgment result and the cell center judgment result in each cell group respectively.

[0025] For example, in a connection state scene, one or more cell groups are set in the terminal, each cell group has at least one serving cell, and for at least one cell group, the terminal determines the low mobility state determination results of each cell group of the terminal based on the measurement results of each cell group and the low mobility state determination criteria. For example, when the measurement result of a cell group meets the low mobility condition of the low mobility state determination criteria, the low mobility state determination result of the terminal in that cell group is in the low mobility state; otherwise, it is not in the low mobility state.

[0026] The terminal determines the cell center determination results of each cell group of the terminal based on the measurement results of each cell group and the cell center determination criteria. For example, when the measurement result of a cell group meets the cell center condition of the cell center determination criteria, the cell center determination result of the terminal in that cell group is at the cell center; otherwise, it is not at the cell center.

[0027] Optionally, the low mobility state determination result of the cell group of the terminal may be determined based on the measurement result of one serving cell in the cell group and the corresponding low mobility state determination criteria, or may be determined based on the measurement results of a plurality of serving cells in the cell group and the respective corresponding low mobility states of the plurality of serving cells. The cell center determination result of the cell group of the terminal may be determined based on the measurement result of one serving cell in the cell group and the corresponding cell center state determination criteria, or may be determined based on the measurement results of a plurality of serving cells in the cell group and the respective corresponding cell center determination results of the plurality of serving cells.

[0028] In step 102, the terminal performs measurement relaxation on the serving cells in each cell group based on the low mobility state determination results and cell center determination results of each cell group.

[0029] Optionally, for any cell group, the terminal determines whether it can perform measurement relaxation on the serving cell within the cell group based on the low mobility state determination result and the cell center determination result of the cell group. If so, the terminal performs measurement relaxation on the serving cell within the cell group. That is, for each cell group, the terminal performs measurement relaxation on the serving cell within the cell group respectively.

[0030] For example, if the low mobility state determination results in both cell group a and cell group b of the terminal are in the low mobility state, and the cell center determination results in both are at the cell center, the terminal performs measurement relaxation on cell group a and cell group b respectively. If the low mobility state determination result in cell group c is not in the low mobility state or the cell center determination result is not at the cell center, the terminal does not perform measurement relaxation on cell group c.

[0031] Optionally, the terminal can further determine for each serving cell within the cell group whether it can perform measurement relaxation based on the low mobility state determination result in the cell group and the cell center determination result of each serving cell within the cell group.

[0032] For example, if the low mobility state determination results in cell group a of the terminal are all in the low mobility state, and the cell center determination results of serving cell 1 and serving cell 2 within cell group a are both at the cell center, the terminal performs measurement relaxation on serving cell 1 and serving cell 2 within cell group a respectively. If the cell center determination result of serving cell 3 within cell group a is not at the cell center, the terminal does not perform measurement relaxation on serving cell 3 within cell group a.

[0033] Optionally, the terminal can further determine for each serving cell within the cell group whether it can perform measurement relaxation based on the low mobility state determination result and the cell center determination result of each serving cell within the cell group.

[0034] For example, when the low mobility state determination results in serving cell 1 and serving cell 2 within cell group a of the terminal are both in the low mobility state, and the cell center determination results are both at the cell center, measurement relaxation is respectively performed on serving cell 1 and serving cell 2 within cell group a. When the low mobility state determination result in serving cell 3 within cell group a is not in the low mobility state, or the cell center determination result is not at the cell center, measurement relaxation is not performed on serving cell 3 within cell group a.

[0035] Measurement relaxation can reduce the power consumption of the terminal, for example, by increasing the measurement interval or not performing measurements for a certain period.

[0036] In the method of this embodiment, the terminal determines the low mobility state determination result and the cell center determination result in each cell group based on the measurement results, low mobility state determination criteria, and cell center determination criteria of each cell group among at least one cell group. Furthermore, based on the low mobility state determination result and the cell center determination result of each cell group, it is respectively determined whether measurement relaxation can be performed on the serving cells within each cell group, and measurement relaxation is respectively performed on the serving cells within each cell group. Thereby, when multiple serving cells are set by the network side device, the terminal can determine whether to perform measurement relaxation according to the actual situation of each cell group or each serving cell, and has relatively high flexibility in terms of the trade-off between communication performance and power saving performance.

[0037] Optionally, measurement relaxation includes at least one of radio link monitoring (RLM) measurement relaxation, beam failure detection (BFD) measurement relaxation, or radio resource management (RRM) measurement relaxation.

[0038] Optionally, the cell group CG for which the low mobility state determination criteria are set includes only the CG under the NR system and does not include the CG of LTE.

[0039] In an embodiment of the present application, the measurement result is a Synchronization Signal and PBCH block (SSB), and a Channel State Information Reference Signal (CSI-RS) for time-frequency domain tracking, and a CSI-RS for measuring the channel state, and a CSI-RS for mobility measurement, and is the measurement result of at least one of the reference signals.

[0040] Optionally, the measurement result is a Reference Signal Received Power (RSRP), and a Reference Signal Received Quality (RSRQ), and a Signal to Interference plus Noise Ratio (SINR), and includes any one or a combination thereof.

[0041] Optionally, when the measurement result is a combination, it includes at least the reference signal received power RSRP.

[0042] Optionally, the RSRP, RSRQ or SINR is the measurement result after smoothing filtering.

[0043] In an embodiment of the present application, how to determine whether to perform measurement relaxation based on the low mobility state determination result and the cell center determination result can be realized as follows.

[0044] One implementation method For any cell group, if the low mobility state determination result in the cell group of the terminal is in the low mobility state and the cell center determination result in the cell group of the terminal is at the cell center, the terminal determines that it will perform measurement relaxation on the serving cell in the cell group, and the cell center determination result is obtained based on the cell center determination result corresponding to at least one serving cell in the cell group.

[0045] Optionally, for any cell group, when two conditions, namely the low mobility condition of the low mobility determination criterion and the cell center condition of the cell center determination criterion, are simultaneously satisfied, it is determined that measurement relaxation will be performed on the serving cell in the cell group, that is, the low mobility state determination result in the cell group of the terminal needs to satisfy being in the low mobility state, and the cell center determination result needs to satisfy being at the cell center.

[0046] Here, the low mobility state determination result in the cell group of the terminal is obtained based on the low mobility state determination result corresponding to at least one serving cell in the cell group, and can be obtained, for example, as follows.

[0047] When the terminal is in the low mobility state in at least one serving cell in the cell group, the terminal determines that the low mobility state determination result in the cell group of the terminal is in the low mobility state, or When the terminal is in the low mobility state in all serving cells in the cell group, the terminal determines that the low mobility state determination result in the cell group of the terminal is in the low mobility state.

[0048] Here, the cell center determination result in the cell group of the terminal is obtained based on the cell center determination result corresponding to at least one serving cell in the cell group, and can be obtained, for example, as follows.

[0049] When the terminal is at the cell center in at least one serving cell within the cell group, the terminal determines whether the cell center determination result in the terminal's cell group is at the cell center, or When the terminal is at the cell center in all serving cells within the cell group, the terminal determines that the cell center determination result in the terminal's cell group is at the cell center.

[0050] For example, when the low mobility state determination result in cell group a of the terminal is in the low mobility state and the cell center determination result is at the cell center, measurement relaxation is performed in cell group a.

[0051] Another implementation method For any cell group, when the low mobility state determination result in the terminal's cell group is in the low mobility state and the cell center determination result in at least one serving cell within the cell group is at the cell center, the terminal determines to perform measurement relaxation in each serving cell among the at least one serving cell.

[0052] Optionally, for any cell group, when the low mobility state determination result in the terminal's cell group is in the low mobility state and the cell center determination result in at least one serving cell within the cell group is at the cell center, the terminal determines to perform measurement relaxation in each serving cell among the at least one serving cell, that is, the terminal performs measurement relaxation only in the serving cell whose cell center determination result is at the cell center.

[0053] For example, when the low mobility state determination results in serving cell 1 and serving cell 2 within cell group a of the terminal are both in the low mobility state and the cell center determination results are both at the cell center, measurement relaxation is respectively performed in serving cell 1 and serving cell 2 within cell group a.

[0054] In the above embodiment, for any cell group, measurement relaxation is executed only when two judgment criteria are simultaneously satisfied. That is, the low-mobility state judgment result in the cell group of the terminal needs to satisfy that it is in the low-mobility state, and the cell center judgment result needs to satisfy that it is at the cell center. Thereby, the communication performance of the terminal can be guaranteed, and measurement relaxation can also be executed for each serving cell in the cell group, with great flexibility.

[0055] In the embodiment of the present application, step 102 further includes several possible implementation manners as follows.

[0056] For the new radio NR master cell group (MCG) in each cell group, when it is determined to execute measurement relaxation for the serving cells in the MCG based on the low-mobility state judgment result and the cell center judgment result of the MCG, the terminal may execute measurement relaxation for the serving cells in all cell groups among all cell groups, or Among each cell group, when it is determined to execute measurement relaxation for the secondary cell group (SCG) based on the low-mobility state judgment result and the cell center judgment result, the terminal executes measurement relaxation for the serving cells in the SCG.

[0057] Optionally, when there is a new radio NR MCG among the multiple cell groups set for the terminal, according to the determination result of executing measurement relaxation in the MCG, it can be determined to execute measurement relaxation in other cell groups. That is, when it is determined to execute measurement relaxation for the serving cells in the MCG based on the low-mobility state judgment result and the cell center judgment result of the MCG, the terminal executes measurement relaxation for the serving cells in all cell groups among all cell groups.

[0058] If there is a secondary cell group (SCG) among each cell group, and it is determined that measurement relaxation is to be executed on the serving cell within the SCG based on the low mobility state determination result and cell center determination result of the SCG, the terminal executes measurement relaxation on the serving cell within the SCG.

[0059] For example, when the low mobility state determination results in both the secondary cell groups SCG1 and SCG2 of the terminal are in the low mobility state, and the cell center determination results are both at the cell center, measurement relaxation is executed on the serving cells within the secondary cell groups SCG1 and SCG2. When the low mobility state determination result in the secondary cell group SCG3 is not in the low mobility state, or the cell center determination result is not at the cell center, measurement relaxation is not executed on the serving cell within SCG3.

[0060] Optionally, when measurement relaxation is not executed on the master cell group (MCG), and the cell center determination results of the SCGs existing in each cell group are at the cell center, and the low mobility state determination results of the SCGs are in the low mobility state, the terminal executes measurement relaxation on the SCG.

[0061] That is, when it is determined that the terminal cannot execute measurement relaxation on the serving cell within the master cell group (MCG), if the cell center determination result and the low mobility state determination result in the secondary cell group (SCG) of the terminal do not simultaneously satisfy the cell center condition and the low mobility condition, measurement relaxation cannot be executed on the serving cell within the SCG. That is, only when the cell center determination result of the SCG is at the cell center and the low mobility state determination result of the SCG is in the low mobility state, can the terminal execute measurement relaxation on the serving cell within the SCG.

[0062] Optionally, for the case of "the terminal performs measurement relaxation on the serving cell in all cell groups among the first situation", for the secondary cell group SCG among all cell groups, it is possible to further determine whether the cell center determination result of the terminal in the SCG is the cell center. If it is the cell center, the terminal performs measurement relaxation on the serving cell in the SCG.

[0063] In the above embodiment, when it is determined that measurement relaxation is performed on the serving cell in the MCG, measurement relaxation can be directly performed on other cell groups without determining whether measurement relaxation can be performed on other cell groups, saving the judgment time and reducing the power consumption of the terminal.

[0064] In the embodiment of the present application, as shown in FIG. 3, the low mobility state determination criterion is set by the network side device, and the setting method of the low mobility state determination criterion includes, for example, being set based on the terminal, being set based on the cell group, or being set based on the serving cell.

[0065] Specifically, being set based on the terminal means that the setting level of the low mobility state determination criterion is the terminal level, that is, the setting is effective for all serving cells in all cell groups of the terminal. Being set based on the cell group means that the setting level of the low mobility state determination criterion is the cell group level, that is, the setting is effective for all serving cells in a specific cell group of the terminal. Being set based on the serving cell means that the setting level of the low mobility state determination criterion is the serving cell level, that is, the setting is effective for a serving cell of the terminal.

[0066] The "the terminal determines the low mobility state determination results in each cell group based on the measurement results of each cell group and the low mobility state determination criterion" in step 101 can be realized in the following several ways.

[0067] One method When the method for setting the low mobility state determination criterion is based on the terminal, the terminal determines the low mobility state determination result in each cell group of the terminal based on the measurement result of the Primary Secondary Cell (PSCell) in the NR secondary cell group SCG that is set by the network side device for the first time, or The terminal determines the low mobility state determination result in each cell group of the terminal based on the measurement result of the Primary Cell (PCell) or the Primary Secondary Cell PSCell of each cell group, or The terminal determines the low mobility state determination result in each cell group of the terminal based on the measurement result of at least one serving cell in each cell group, or When the method for setting the low mobility state determination criterion is based on the cell group, The terminal determines the low mobility state determination result in each cell group of the terminal based on the measurement result of the Primary Cell PCell or the Primary Secondary Cell PSCell of each cell group, or The terminal determines the low mobility state determination result in each cell group of the terminal based on the measurement result of at least one serving cell in each cell group.

[0068] Optionally, the network side device can set the low mobility state determination criterion based on the terminal, the serving cell, or the cell group. Depending on the setting method, the method by which the terminal determines the low mobility state of the cell group may be different. That is, the terminal needs to know based on the measurement results of which cells or which combination of cells in the cell group the terminal determines the low mobility state of the cell group. Therefore, the terminal needs to know the current setting method of the low mobility state determination criterion from the network side device, and the terminal determines the low mobility state of the cell group according to the setting method.

[0069] Here, regarding the setting method based on the terminal, the low-mobility state determination criteria set for the terminal are also applicable to each cell group. That is, the same low-mobility state determination criteria can be used for each cell group. For a certain terminal, the low-mobility state determination criteria may or may not be set.

[0070] Regarding the setting method based on the cell group, the low-mobility state determination criteria are set for different cell groups respectively. The numerical values of the correlation parameters of the low-mobility state determination criteria set for different cell groups may be the same or different. For a certain cell group, the low-mobility state determination criteria may or may not be set. If the low-mobility state determination criteria are not set for a certain cell group, the terminal does not need to determine whether it is in a low-mobility state in that cell group and does not perform measurement relaxation in that cell group.

[0071] Regarding the setting method based on the serving cell, the low-mobility state determination criteria are set for different serving cells respectively. The numerical values of the correlation parameters of the low-mobility state determination criteria set for different serving cells may be the same or different. For a certain serving cell, the low-mobility state determination criteria may or may not be set. If the low-mobility state determination criteria are not set for a certain serving cell, the terminal does not need to determine whether it is in a low-mobility state in that serving cell and does not perform measurement relaxation in that serving cell.

[0072] For any cell group, in the first situation where the "low mobility state determination criterion setting method is terminal-based", the terminal determines the low mobility state determination result in the cell group of the terminal based on the measurement result of the primary secondary cell (PSCell) in the NR SCG that is set by the network-side device for the first time. That is, it determines whether the low mobility state determination result in the cell group of the terminal is a low mobility state. For example, the measurement result of the primary secondary cell (PSCell) is compared with a certain measurement reference value. If the difference is small, the terminal is in a low mobility state; if the difference is large, the terminal is not in a low mobility state. Here, the "first setting" includes, for example, the RRC reconfiguration message containing the first SCG setting received after the terminal enters the RRC connected state. Here, the initial value of the measurement reference value may be set by the network-side device or determined by the terminal itself. Optionally, the measurement reference value may be further updated based on the measurement result. That is, in this case, the low mobility state determination result in the cell group of the terminal can be indicated by using the low mobility state determination result of the primary secondary cell (PSCell) of the terminal.

[0073] For the second situation in the case of "the setting method of the low mobility state determination criterion is terminal-based", the terminal determines the low mobility state determination result in the cell group of the terminal based on the measurement results of the primary cell (PCell) or the primary secondary cell (PSCell) of the cell group, that is, determines whether the low mobility state determination result in the cell group of the terminal is in the low mobility state. When the primary cell (PCell) exists, the low mobility state determination result in the cell group of the terminal is determined based on the measurement results of the primary cell (PCell). When the primary cell (PCell) does not exist and the primary secondary cell (PSCell) exists, the low mobility state determination result in the cell group of the terminal is determined based on the measurement results of the primary secondary cell (PSCell). For example, the measurement results of the primary cell (PCell) or the primary secondary cell (PSCell) are compared with a certain measurement reference value. If the difference is small, the terminal is in the low mobility state; if the difference is large, the terminal is not in the low mobility state. That is, in this case, the low mobility state determination result in the cell group of the terminal can be indicated by using the low mobility state determination result of the primary cell (PCell) or the primary secondary cell (PSCell) of the terminal.

[0074] For the third situation in the case of "the setting method of the low mobility state determination criterion is terminal-based", the terminal determines the low mobility state determination result in the cell group of the terminal based on the measurement results of each serving cell in the cell group, that is, determines whether the low mobility state determination result in the cell group of the terminal is in the low mobility state. For example, when the low mobility determination results of each serving cell of the terminal can be determined respectively, it is determined whether the low mobility state determination result in the cell group of the terminal is in the low mobility state based on the low mobility determination results of each serving cell of the terminal. For example, if the terminal is in the low mobility state in at least one of the serving cells, it can be determined that the low mobility state determination result in the cell group of the terminal is in the low mobility state, or if the terminal is in the low mobility state in all the serving cells, it can be determined that the low mobility state determination result in the cell group of the terminal is in the low mobility state.

[0075] For the first situation in the case of "the setting method of the low mobility state determination criterion is based on a cell group", based on the measurement results of the primary cell (PCell) or the primary secondary cell (PSCell) of the cell group, the terminal determines the low mobility state determination result in the cell group of the terminal, which is similar to the embodiment set based on the terminal, and the description is omitted here.

[0076] For the second situation in the case of "the setting method of the low mobility state determination criterion is based on a cell group", based on the measurement results of each serving cell in the cell group, the terminal determines the low mobility state determination result in the cell group of the terminal, which is similar to the embodiment set based on the terminal, and the description is omitted here.

[0077] Optionally, "the terminal determines the low mobility state determination result in the cell group of the terminal based on the measurement results of each serving cell in the cell group" can be realized in the following several ways.

[0078] When the terminal is in a low mobility state in at least one serving cell in the cell group, the terminal determines that the low mobility state determination result in the cell group of the terminal is in a low mobility state. When the terminal is in a low mobility state in all serving cells in the cell group, the terminal determines that the low mobility state determination result in the cell group of the terminal is in a low mobility state.

[0079] In the above embodiment, according to the setting method of the low mobility state determination criterion transmitted by the network side device, the terminal can determine based on the measurement results of which serving cells in the cell group to determine the low mobility determination result in the cell group of the terminal, and the processing complexity is low.

[0080] In the embodiments of the present application, the cell center determination criterion may be set by the network side device, may be predefined, or may be implicitly set.

[0081] The network-side device can set cell center judgment criteria based on a terminal, a serving cell, or a cell group. Depending on the setting method, the method by which the terminal determines the cell center judgment result of the cell group may be different. That is, the terminal needs to know based on the measurement results of which cell or cells in the cell group to determine the cell center judgment result of the terminal in the cell group. Therefore, the terminal needs to know whether the cell center judgment criteria are set for each serving cell in the current cell group, and further determine the cell center judgment result of the terminal in the cell group.

[0082] Here, for the setting method based on the terminal, the cell center judgment criteria set for the terminal are also applicable to each cell group. For a certain terminal, the cell center judgment criteria may or may not be set.

[0083] For the setting method based on the cell group, the cell center judgment criteria are set for different cell groups respectively. The numerical values of the correlation parameters of the cell center judgment criteria set for different cell groups may be the same or different. For a certain cell group, the cell center judgment criteria may or may not be set. If the cell center judgment criteria are not set for a certain cell group, the criteria for the terminal to determine whether it is at the cell center in the cell group are predefined by the protocol or customized by the terminal.

[0084] Regarding the setting method based on the serving cell, for different serving cells, the cell center judgment criteria are set respectively. The numerical values of the correlation parameters of the cell center judgment criteria set for different serving cells may be the same or different. For a certain serving cell, the cell center judgment criteria may or may not be set. When the cell center judgment criteria are not set for a certain serving cell, the criteria for the terminal to determine whether it is at the cell center in the serving cell are predefined by the protocol or customized by the terminal.

[0085] When the cell center judgment criteria are not set by the network-side device, for example, when they are predefined, when determining the cell center judgment result in the cell group of the terminal, it can be determined based on the same setting method as the low mobility state judgment criteria. Optionally, when the low mobility state judgment criteria are set by the network-side device, if the setting method of the low mobility state judgment criteria is based on the terminal, the setting method of the cell center judgment criteria is based on the terminal, if the setting method of the low mobility state judgment criteria is based on the cell group, the setting method of the cell center judgment criteria is based on the cell group, if the setting method of the low mobility state judgment criteria is based on the serving cell, the setting method of the cell center judgment criteria is based on the serving cell.

[0086] In the above embodiments, the flexibility of setting the cell center judgment criteria is high. Whether it is at the cell center is related to the implementation performance and algorithm of the terminal. Therefore, the actual setting method of the cell center judgment criteria may be relatively flexible. By determining the setting method of the cell center judgment criteria according to the setting method of the low mobility state judgment criteria, a relatively good effect of reducing the signaling overhead can be achieved.

[0087] In the embodiments of this application, "the terminal determines the cell center determination results for each cell group based on the measurement results of each cell group and the cell center determination criteria" in step 101 can be implemented as follows.

[0088] When the setting method of the cell center determination criteria is based on the terminal, the terminal determines the cell center determination results for each cell group of the terminal based on the measurement results of the primary secondary cell (PSCell) in the NR secondary cell group (SCG) initially set by the network-side device, or the terminal determines the cell center determination results for each cell group of the terminal based on the measurement results of the primary cell (PCell) or the primary secondary cell (PSCell) of each cell group, or the terminal determines the cell center determination results for each cell group of the terminal based on the measurement results of each serving cell in each cell group. When the setting method of the cell center determination criteria is based on the cell group, the terminal determines the cell center determination results for each cell group of the terminal based on the measurement results of the primary cell (PCell) or the primary secondary cell (PSCell) of each cell group, or the terminal determines the cell center determination results for each cell group of the terminal based on the measurement results of each serving cell in each cell group.

[0089] Optionally, for any cell group, in the first situation where the "cell center determination criterion setting method is terminal-based", the terminal determines the cell center determination result in the cell group of the terminal based on the measurement result of the primary secondary cell (PSCell) in the NR SCG that is set by the network-side device for the first time. That is, it determines whether the cell center determination result in the cell group of the terminal is the cell center. For example, compare the measurement result of the primary secondary cell (PSCell) with a certain threshold. If it is greater than or equal to the threshold, the terminal is at the cell center; if it is less than the threshold, the terminal is not at the cell center. Here, the threshold may be set by the network-side device or determined by the terminal itself. That is, in this case, the cell center determination result in the cell group of the terminal can be indicated by using the cell center determination result of the primary secondary cell (PSCell) of the terminal.

[0090] For the second situation where the "cell center determination criterion setting method is terminal-based", the terminal determines the low mobility state determination result in the cell group of the terminal based on the measurement result of the primary cell (PCell) or the primary secondary cell (PSCell) of the cell group. That is, it determines whether the cell center determination result in the cell group of the terminal is the cell center. If the primary cell (PCell) exists, determine the cell center determination result in the cell group of the terminal based on the measurement result of the primary cell (PCell). If the primary cell (PCell) does not exist and the primary secondary cell (PSCell) exists, determine the cell center determination result in the cell group of the terminal based on the measurement result of the primary secondary cell (PSCell). For example, compare the measurement result of the primary cell (PCell) or the primary secondary cell (PSCell) with a certain threshold. If it is greater than or equal to the threshold, the terminal is at the cell center; if it is less than the threshold, the terminal is not at the cell center. That is, in this case, the cell center determination result in the cell group of the terminal can be indicated by using the cell center determination result of the primary cell (PCell) or the primary secondary cell (PSCell) of the terminal.

[0091] For the third situation in the case where "the cell center determination criterion setting method is terminal-based", the terminal determines the cell center determination result in the terminal's cell group based on the measurement results of each serving cell in the cell group, that is, determines whether the cell center determination result of the terminal in the cell group is the cell center. For example, when the cell center determination result of each serving cell of the terminal can be determined respectively, based on the cell center determination result of each serving cell of the terminal, it is determined whether the cell center determination result of the terminal in the cell group is the cell center. For example, if in at least one of the serving cells the terminal is at the cell center, it can be determined that the cell center determination result of the terminal in the cell group is the cell center, or if the terminal is at the cell center in all the serving cells, it can be determined that the cell center determination result of the terminal in the cell group is the cell center.

[0092] For the first situation in the case where "the cell center determination criterion setting method is cell group-based", the terminal determines the cell center determination result in the terminal's cell group based on the measurement results of the primary cell (PCell) or the primary secondary cell (PSCell) of the cell group, which is similar to the embodiment set based on the terminal, and the description is omitted here.

[0093] For the second situation in the case where "the cell center determination criterion setting method is cell group-based", the terminal determines the cell center determination result in the terminal's cell group based on the measurement results of each serving cell in the cell group, which is similar to the embodiment set based on the terminal, and the description is omitted here.

[0094] Optionally, "the terminal determines the cell center determination result in the terminal's cell group based on the measurement results of each serving cell in the cell group" can be realized in the following several ways.

[0095] When the terminal is at the cell center in at least one serving cell within the cell group, the terminal determines that the cell center determination result of the terminal in the cell group is at the cell center. When the terminal is also at the cell center in all serving cells within the cell group, the terminal determines that the cell center determination result of the terminal in the cell group is at the cell center.

[0096] In the above embodiment, according to the setting method of the cell center determination criterion, the terminal can determine based on the measurement results of which serving cells within the cell group to determine the cell center determination result of the terminal in the cell group, and the processing complexity is low.

[0097] In the embodiments of the present application, "the terminal determines the low mobility state determination result of the terminal in the cell group based on the measurement results of the primary cell PCell or the primary secondary cell PSCell of the cell group" can be realized as follows.

[0098] When the cell group includes a cell in the first frequency band and a cell in the second frequency band, for the first frequency band where the primary cell PCell or the primary secondary cell PSCell exists, the terminal determines the low mobility state determination result of the terminal in the first frequency band based on the measurement results of the primary cell PCell or the primary secondary cell PSCell. For the second frequency band where the primary cell PCell or the primary secondary cell PSCell does not exist, the terminal determines the low mobility state determination result of the first frequency band as the low mobility determination result of the terminal in the second frequency band.

[0099] Selectively, assuming that a cell group includes cells of multiple frequency bands, for example, a cell of a first frequency band and a cell of a second frequency band, if there is a primary cell PCell or a primary secondary cell PSCell among the cells of the first frequency band, and there is no primary cell PCell or primary secondary cell PSCell among the cells of the second frequency band, the terminal determines the low mobility state determination result of the terminal in the first frequency band based on the primary cell PCell or the primary secondary cell PSCell. That is, when the primary cell PCell exists, based on the measurement result of the primary cell PCell, the low mobility state determination result of the terminal in the first frequency band is determined. When the primary cell PCell does not exist and the primary secondary cell PSCell exists, based on the measurement result of the primary secondary cell PSCell, the low mobility state determination result of the terminal in the first frequency band is determined. That is, in this case, the low mobility state determination result of the terminal in the primary cell PCell or the primary secondary cell PSCell of the terminal can be used to indicate the low mobility state determination result of the terminal in the first frequency band.

[0100] Furthermore, the terminal determines the low mobility state determination result of the first frequency band as the low mobility determination result of the terminal in the second frequency band. That is, the low mobility determination result of the terminal in the second frequency band can adopt the low mobility state determination result of the first frequency band.

[0101] In the above embodiment, for different frequency bands, the low mobility state determination results of the terminal in different frequency bands can be determined respectively, and the flexibility is high.

[0102] In the embodiments of the present application, "the terminal determines the cell center determination result of the terminal in the cell group based on the measurement result of the primary cell PCell or the primary secondary cell PSCell of the cell group" can be realized as follows.

[0103] When the cell group includes a cell in the first frequency band and a cell in the second frequency band, for the first frequency band in which the primary cell PCell or the primary secondary cell PSCell exists, the terminal determines the cell center determination result of the terminal in the first frequency band based on the measurement result of the primary cell PCell or the primary secondary cell PSCell. For the second frequency band in which the primary cell PCell or the primary secondary cell PSCell does not exist, the terminal determines the cell center determination result of the terminal in the second frequency band based on the measurement result of the secondary cell SCell in the second frequency band.

[0104] Optionally, for the first frequency band, the terminal determines the cell center determination result of the terminal in the first frequency band based on the primary cell PCell or the primary secondary cell PSCell. That is, when the primary cell PCell exists, the cell center determination result of the terminal in the first frequency band is determined based on the measurement result of the primary cell PCell. When the primary cell PCell does not exist and the primary secondary cell PSCell exists, the cell center determination result of the terminal in the first frequency band is determined based on the measurement result of the primary secondary cell PSCell. That is, in this case, the cell center determination result of the terminal in the primary cell PCell or the primary secondary cell PSCell of the terminal can be used to indicate the cell center determination result of the terminal in the first frequency band.

[0105] For the second frequency band, since there is no primary cell PCell or primary secondary cell PSCell among the cells in the second frequency band, the cell center determination result of the terminal in the second frequency band is determined based on the measurement result of the secondary cell SCell in the second frequency band.

[0106] For different frequency bands, the cell center determination results of the terminal in different frequency bands can be determined respectively.

[0107] Optionally, step 102 may be as follows.

[0108] Based on the low mobility state determination result and cell center determination result of the terminal in the first frequency band, the terminal performs measurement relaxation on the serving cell in the first frequency band. Based on the low mobility state determination result and cell center determination result of the terminal in the second frequency band, the terminal performs measurement relaxation on the serving cell in the second frequency band.

[0109] Optionally, for different frequency bands, it can be determined respectively whether the terminal performs measurement relaxation on the serving cells in different frequency bands.

[0110] In the above embodiment, for different frequency bands, the low mobility state determination results and cell center determination results of the terminal in different frequency bands can be determined respectively, and further, measurement relaxation can be performed respectively in different frequency bands, which has high flexibility.

[0111] In the embodiment of the present application, "Based on the measurement results of each cell group and the low mobility state determination criteria, the low mobility state determination results of each cell group are determined respectively" in step 101 can be realized as follows.

[0112] When the setting method of the low mobility state determination criteria is based on the serving cell for any cell group, Based on the measurement results of the first or most recent serving cell for which the low mobility state determination criteria are set, the terminal determines the low mobility state determination results of each of the above cell groups of the terminal, or Based on the measurement results of the primary cell PCell or primary secondary cell PSCell of each cell group, the terminal determines the low mobility state determination results of each cell group of the terminal respectively, or Based on the measurement results of at least one serving cell in each cell group, the terminal determines the low mobility state determination results of each cell group of the terminal respectively.

[0113] Optionally, for the first situation in the case where "the setting method of the low mobility state determination criterion is based on the serving cell", the terminal determines the low mobility state determination result in the cell group of the terminal based on the measurement result of the first or the most recent serving cell for which the low mobility state determination criterion is set, that is, determines whether the low mobility state determination result of the terminal in the cell group is in the low mobility state. For example, the measurement result of the serving cell is compared with a certain measurement reference value. If the difference is small, the terminal is in the low mobility state; if the difference is large, the terminal is not in the low mobility state. Here, the initial value of the measurement reference value may be set by the network-side device or determined by the terminal itself.

[0114] Here, the first or the most recent serving cell for which the low mobility state determination criterion is set refers to the first serving cell for which the setting is made or the most recent serving cell for which the setting is made when the network-side device sets the low mobility state determination criterion. For example, the network-side device respectively instructs that the low mobility state determination criterion is set for serving cell 1, serving cell 2, and serving cell 3. For example, when setting the low mobility state determination criterion for only one serving cell at a time, serving cell 1 is the first serving cell for which the low mobility state determination criterion is set, and the most recent serving cell for which the setting is made is, for example, the serving cell corresponding to the setting closest to the current time.

[0115] In this case, the low mobility state determination result in the first or the most recent serving cell for which the low mobility state determination criterion of the terminal is set can be used to indicate the low mobility state determination result in the cell group of the terminal.

[0116] For the second situation in the case of "the setting method of the low mobility state determination criterion is based on the serving cell", the terminal determines the low mobility state determination result in the cell group of the terminal based on the measurement results of the primary cell PCell or the primary secondary cell PSCell of the cell group, that is, determines whether the low mobility state determination result of the cell group of the terminal is in the low mobility state. When the primary cell PCell exists, based on the measurement results of the primary cell PCell, determine the low mobility state determination result in the cell group of the terminal. When the primary cell PCell does not exist and the primary secondary cell PSCell exists, based on the measurement results of the primary secondary cell PSCell, determine the low mobility state determination result in the cell group of the terminal. For example, compare the measurement results of the primary cell PCell or the primary secondary cell PSCell with a certain measurement reference value. If the difference is small, the terminal is in the low mobility state. If the difference is large, the terminal is not in the low mobility state. That is, in this case, the low mobility state determination result in the cell group of the terminal can be indicated by using the low mobility state determination result of the primary cell PCell or the primary secondary cell PSCell of the terminal.

[0117] For the third situation in the case of "the setting method of the low mobility state determination criterion is based on the serving cell", the terminal determines the low mobility state determination result in the cell group of the terminal based on the measurement results of each serving cell in the cell group, that is, determines whether the low mobility state determination result of the cell group of the terminal is in the low mobility state. For example, when the low mobility determination results of each serving cell of the terminal can be determined respectively, based on the low mobility determination results of each serving cell of the terminal, determine whether the low mobility state determination result of the cell group of the terminal is in the low mobility state. For example, if the terminal is in the low mobility state in at least one of the serving cells, it can be determined that the low mobility state determination result of the cell group of the terminal is in the low mobility state, or if the terminal is in the low mobility state in all the serving cells, it can be determined that the low mobility state determination result of the cell group of the terminal is in the low mobility state.

[0118] In the above embodiment, the terminal can determine, according to the setting method of the low mobility state determination criterion sent by the network-side device, based on the measurement results of which serving cells in the cell group, whether to determine the low mobility determination result of the terminal in the cell group, and the processing complexity is low.

[0119] In the embodiment of the present application, "determining the cell center determination result in each cell group based on the measurement result of each cell group and the cell center determination criterion" in step 101 can be realized as follows.

[0120] When the setting method of the cell center determination criterion is based on the serving cell, the terminal determines the cell center determination result in each cell group of the terminal based on the measurement result of the first or the most recent serving cell for which the cell center determination criterion is set, or the terminal determines the cell center determination result in each cell group of the terminal based on the measurement result of the primary cell (PCell) or the primary secondary cell (PSCell) of each cell group, or the terminal determines the cell center determination result in each cell group of the terminal based on the measurement result of each serving cell in each cell group.

[0121] Optionally, when the setting method of the cell center determination criterion is based on the serving cell, for any cell group, determining the cell center determination result in the cell group of the terminal is similar to determining the low mobility state determination result in the cell group of the terminal, and the description is omitted here.

[0122] In the above embodiment, the terminal can determine, according to the setting method of the low mobility state determination criterion sent by the network-side device, based on the measurement results of which serving cells in the cell group, whether to determine the cell center determination result of the terminal in the cell group, and the processing complexity is low.

[0123] Optionally, when the setting method of the cell center determination criterion is based on the serving cell, for the case of "the terminal determines the low mobility state determination result in the cell group of the terminal based on the measurement result of the primary cell PCell or the primary secondary cell PSCell of the cell group", performing measurement relaxation based on the low mobility state determination result in the cell group of the terminal can be realized as follows.

[0124] The terminal determines the cell center determination result in the cell group of the terminal based on the measurement result of the secondary cell SCell for performing beam failure detection BFD measurement. The terminal performs BFD measurement relaxation on the serving cell in the cell group based on the low mobility state determination result in the cell group of the terminal and the cell center determination result in the cell group of the terminal.

[0125] Optionally, for a certain secondary cell SCell of the cell group, regarding whether the terminal needs to perform BFD measurement on the SCell, if necessary, the terminal determines the cell center determination result in the cell group of the terminal based on the measurement result of the SCell, and then determines whether to perform BFD measurement relaxation on the serving cell in the cell group based on the low mobility state determination result and the cell center determination result in the cell group of the terminal. The low mobility state determination result is determined based on the measurement result of the primary cell PCell or the primary secondary cell PSCell of the cell group.

[0126] When the secondary cell SCell belongs to the third frequency band of the cell group, the terminal cannot determine whether to perform BFD measurement relaxation on the serving cell in the cell group based on the measurement result of another SCell in the third frequency band or an SCell in another frequency band of the cell group.

[0127] In the above embodiment, regarding BFD measurement relaxation, based on the measurement results of the SCell for determining the BFD measurement, the cell center determination result in the cell group of the terminal is determined, and based on the low mobility state determination result in the cell group of the terminal, the execution of measurement relaxation can be determined, reducing the measurement overhead and making the cells for which measurement relaxation is executed more targeted.

[0128] In the embodiments of the present application, the measurement relaxation method When the terminal is in the idle state and it is determined that the terminal is in a low mobility state in the cell group, after entering the connected state, the terminal determines that the low mobility state determination result is in the low mobility state, and further includes the step of transmitting the low mobility state determination result to the network side device.

[0129] Optionally, when the terminal is in the idle state, for the frequency points of the primary cell (PCell) or the primary secondary cell (PSCell) or the secondary cell (SCell), related measurements that may be early measurements in, for example, the DC scenario or the SCell scenario, have been performed, and based on the low mobility state determination criteria in the idle state, when the terminal determines that it is in a low mobility state in the idle state, the terminal is in a low mobility state and can be reused in the connected state, that is, it is determined that the terminal is in a low mobility state even in the connected state, and after entering the connected state, the terminal reports to the network side device that it is in a low mobility state.

[0130] In the above embodiment, the result of the low mobility state determined by the terminal in the idle state is applied to the connected state, and the terminal does not need to make a judgment again based on the measurement results, reducing unnecessary processing procedures, further reducing the power consumption of the terminal, and saving processing time.

[0131] In the embodiments of the present application, the measurement relaxation method Within the determination period set by the network-side device, the step of the terminal determining whether the low mobility determination result in the cell group of the terminal is in a low mobility state; When the low mobility determination result in the cell group of the terminal is not in a low mobility state, the step of the terminal stopping the execution of measurement relaxation in the cell group is further included.

[0132] Furthermore, when the low mobility determination result in the cell group of the terminal is in a low mobility state, the measurement relaxation method is as follows: The step of the terminal determining whether the terminal is at the cell center in the cell group; When the terminal is not at the cell center in the cell group, the step of the terminal stopping the execution of measurement relaxation in the cell group is further included.

[0133] Here, the determination period of the low mobility state may be the paging cycle period set by the network, or other values set by the network.

[0134] Optionally, during the execution of measurement relaxation, continuously determine whether the low mobility state is satisfied. If the low mobility state is not satisfied, exit the measurement relaxation state. Also, the terminal determines whether it is necessary to exit the measurement relaxation state because it does not meet the cell center determination criterion based on the current measurement result.

[0135] Optionally, when the terminal determines that it no longer satisfies the low mobility state, it may report to the network-side device whether it is currently in the low mobility state, or report whether it is at the cell center.

[0136] In the embodiments of the present application, the cell center determination criterion may be predefined or implicitly set. For any serving cell in each cell group, the terminal determines that the cell center determination criterion in the serving cell of the terminal becomes effective based on the first indication information of the network-side device.

[0137] For example, a 1-bit indication bit is used to indicate whether the cell center determination criterion is valid or not.

[0138] Optionally, the setting method of the cell center determination criterion may be determined based on the setting method of the first indication information. For example, if the setting method of the first indication information is based on the terminal, the cell center determination criterion also adopts a setting method based on the terminal. If the setting method of the first indication information is based on the serving cell, the cell center determination criterion also adopts a setting method based on the serving cell. If the setting method of the first indication information is based on the cell group, the cell center determination criterion also adopts a setting method based on the cell group.

[0139] In the above embodiment, the terminal can determine whether the cell center determination criterion is valid based on the indication information sent by the network-side device, or can also determine the setting method adopted for the cell center determination criterion based on the setting method of the indication information. Furthermore, it can be determined based on the measurement results of which serving cells in the cell group to determine the cell center determination result of the terminal in the cell group, and the processing complexity is low.

[0140] Exemplarily, for the low mobility state determination criterion set based on the terminal, for example, in the CA / DC scenario of the connected state, the measurement relaxation method includes the following steps 1a, 2a, 3a, and 4a.

[0141] In step 1a, receive the correlation parameters of the low mobility state determination criterion, such as the time duration T SearchDeltaP , threshold S SearchDeltaP set by the network-side device, and the correlation parameters of the cell center determination criterion such as the judgment period, etc.

[0142] Optionally, the correlation parameter of the cell center determination criterion may not be set, or may be set implicitly. For example, based on the indication information on whether the cell center determination criterion is effective, in a certain cell where the terminal performs RLM or BFD or RRM measurement within the CG, the terminal needs to determine whether it is necessary to determine whether the cell center determination criterion is satisfied. If it is necessary to make a determination, the terminal will determine the correlation parameter of the cell center determination criterion by itself.

[0143] In the case of the setting method based on the terminal, the setting of the low mobility state determination criterion may be effective for all CGs. For example, when the UE can search for the NR system information block (System Information Block, SIB), that is, when the NR primary cell (PCell) exists, the low mobility state determination criterion may be directly set in SIB2. The network-side device may set the low mobility state determination criterion in a certain signaling (for example, radio resource control (RRC) connection establishment signaling). When NR cannot search for the NR SIB, that is, when the NR primary cell (PCell) does not exist, the low mobility state determination criterion is given in a certain signaling (for example, radio resource control (RRC) signaling) loaded in the NR secondary cell group (SCG). In this case, the network-side device may set the low mobility state determination criterion only in the signaling of the newly set NR SCG.

[0144] When the setting of the low mobility state determination criterion is effective for all CGs, based on other information, it is determined whether a certain serving cell needs RLM / BFD measurement. In the cells where measurement is required, it is determined whether RLM / BFD measurement relaxation is possible based on the cell center determination criterion. These cells that require RLM / BFD measurement include at least all PCells and PSCs, and also include some SCells that require BFD measurement.

[0145] Optionally, the measurement relaxation may include RRM measurement relaxation. Since RRM measurements are required in all serving cells, if the setting of the low mobility state determination criterion is effective for all CGs, the terminal can further determine, in each serving cell, whether measurement relaxation is possible based on the set or predefined cell center determination criterion.

[0146] Optionally, the network-side device can further indicate, in a certain serving cell, by indication information, for example, by setting a 1-bit indication bit in the indication information, whether it is possible to perform RLM / BFD / RRM measurement relaxation in the serving cell. For example, when the indication bit is set to 1, it indicates that RLM / BFD / RRM measurement relaxation is not performed in the cell.

[0147] Through the setting of the low mobility state determination criterion that is effective for all CGs and the measurement relaxation indication that is only effective for a certain serving cell, the network can more flexibly control the measurement relaxation operation of the terminal in a specific cell of the terminal and guarantee the performance of the terminal.

[0148] In step 2a, based on the low mobility state determination criterion set by the network-side device, the terminal starts to judge the measurement results of the corresponding serving cell in the serving cell, determines the low mobility state judgment result, and determines the cell center judgment result based on the cell center determination criterion. Specifically, refer to the foregoing embodiments.

[0149] Optionally, when the terminal determines that it can perform RLM / BFD / RRM measurement relaxation in the primary cell PCell or the primary secondary cell PSCell within the CG, the secondary cell SCell also performs RLM / BFD / RRM measurement relaxation.

[0150] Optionally, when a certain CG contains different cells in multiple frequency bands, the terminal determines whether the cells in the frequency band need RLM / BFD / RRM measurement relaxation based on the measurement results of the primary cell PCell or the primary secondary cell PSCell in the frequency band where the primary cell PCell or the primary secondary cell PSCell is included. In the frequency band where the primary cell PCell or the primary secondary cell PSCell is not included, the terminal determines whether to perform RLM / BFD / RRM measurement relaxation based on the measurement results of the SCell.

[0151] Optionally, in the frequency band where the PCell or PSCell is not included, the terminal only determines whether the cell center judgment criterion is met, that is, whether it is at the cell center, based on the measurement results of the SCell. Furthermore, based on the low mobility state judgment result corresponding to the PCell or PSCell in the same CG, it is determined whether to perform RLM / BFD / RRM measurement relaxation.

[0152] Optionally, when the judgment result of the MCG is that RLM / BFD / RRM measurement relaxation can be performed, RLM / BFD / RRM measurement relaxation is performed for all CGs. When the judgment result of only one or more SCGs is that RLM / BFD / RRM measurement relaxation can be performed, RLM / BFD / RRM measurement relaxation is performed only for the SCGs determined to be measurement-relaxable.

[0153] When the judgment result of the MCG is that RLM / BFD / RRM measurement relaxation can be performed, RLM / BFD / RRM measurement relaxation is performed as long as the judgment of the SCG meets the cell center judgment criterion. When the judgment result of the MCG is that RLM / BFD / RRM measurement relaxation cannot be performed, the SCG cannot perform RLM / BFD / RRM measurement relaxation unless it simultaneously meets the cell center judgment criterion and the low mobility state judgment criterion.

[0154] In step 3a, after determining the execution of measurement relaxation, the terminal enters the corresponding measurement relaxation state, and according to the determination period setting requirement of the low mobility state, continuously determines whether it meets the low mobility state. If it does not meet, it exits the measurement relaxation state. In addition, the terminal further determines based on the current measurement result whether it is necessary to exit the measurement relaxation state because it does not meet the cell center determination criterion.

[0155] In step 4a, the terminal exits the measurement relaxation state and returns to step 2a to continuously determine.

[0156] Exemplarily, for the low mobility state determination criterion set based on the cell group, for example, in the CA / DC scenario of the connected state, the measurement relaxation method includes the following steps 1b, 2b, 3b, and 4b.

[0157] In step 1b, the time length T SearchDeltaP , threshold S SearchDeltaP , correlation parameters of the low mobility state determination criterion such as the determination period, and correlation parameters of the cell center determination criterion such as the threshold are received.

[0158] Optionally, the correlation parameters of the cell center determination criterion may not be set, or may be set implicitly. For example, the terminal determines whether it is necessary to determine whether it meets the cell center determination criterion in a certain cell that performs RLM or BFD or RRM measurement within the CG based on the indication information on whether the cell center determination criterion is effective. If determination is necessary, the terminal determines the correlation parameters of its cell center determination criterion by itself.

[0159] In the setting method based on the cell group, the low mobility state determination criterion may be set with correlation parameters in the CG setting, so it is only effective for the current CG. Optionally, the set CG can only be the NR CG and cannot be the LTE CG.

[0160] The terminal determines whether it is in a low-mobility state based on the measurement results of the PSCell within the NR SCG, and can further apply the determination result to all serving cells in the SCG. The terminal can also determine the low-mobility state based on the measurement results of each serving cell respectively.

[0161] In the CG where the low-mobility state determination criterion is set, the terminal further determines, based on other information, whether a certain serving cell requires RLM / BFD measurement. For the cells that require measurement, it is determined whether RLM / BFD measurement relaxation is possible based on the cell center determination criterion. These cells that require RLM / BFD measurement include at least all PCells and PSCs, and also include some SSCs that require BFD measurement.

[0162] Optionally, the network-side device can further indicate, in a certain serving cell, by indication information, for example, by setting a 1-bit indication bit in the indication information, whether RLM / BFD / RRM measurement relaxation can be performed in the serving cell. For example, when the indication bit is set to 1, it indicates that RLM / BFD / RRM measurement relaxation is not performed in the cell.

[0163] Through the setting of the low-mobility state determination criterion that is valid for all CGs and the measurement relaxation indication that is only valid for a certain serving cell, the network can more flexibly control the measurement relaxation operation of the terminal in a certain specific cell and guarantee the performance of the terminal.

[0164] In step 2b, the terminal starts to determine the measurement results of the corresponding serving cell based on the low-mobility state determination criterion set by the network-side device in the corresponding serving cell, determines the low-mobility state determination result, and determines the cell center determination result based on the cell center determination criterion. Specifically, refer to the foregoing embodiments.

[0165] Optionally, if the terminal determines that it can perform RLM / BFD / RRM measurement relaxation on the primary cell PCell or the primary-secondary cell PSCell within the CG, the secondary cell SCell also performs RLM / BFD / RRM measurement relaxation.

[0166] Optionally, if a CG contains different cells in multiple frequency bands, the terminal, in the frequency band containing the primary cell PCell or the primary-secondary cell PSCell, determines whether the cells in that frequency band require RLM / BFD / RRM measurement relaxation based on the measurement results of the primary cell PCell or the primary-secondary cell PSCell. In the frequency band without the primary cell PCell or the primary-secondary cell PSCell, the terminal determines whether to perform RLM / BFD / RRM measurement relaxation based on the measurement results of the SCell.

[0167] Optionally, in the frequency band without the PCell or PSCell, the terminal only determines whether it meets the cell center judgment criterion, that is, whether it is at the cell center, based on the measurement results of the SCell. Furthermore, based on the low mobility state judgment result corresponding to the PCell or PSCell within the same CG, it determines whether to perform RLM / BFD / RRM measurement relaxation.

[0168] Optionally, if the determination result of the MCG is that RLM / BFD / RRM measurement relaxation can be performed, RLM / BFD / RRM measurement relaxation is performed for all CGs. If the determination result is that RLM / BFD / RRM measurement relaxation can be performed for only one or more SCGs, RLM / BFD / RRM measurement relaxation is performed only for the SCGs determined to be capable of measurement relaxation.

[0169] When the determination result of the MCG indicates that RLM / BFD / RRM measurement relaxation can be performed, as long as the determination of the SCG meets the cell center determination criteria, RLM / BFD / RRM measurement relaxation is performed. When the determination result of the MCG indicates that RLM / BFD / RRM measurement relaxation cannot be performed, the SCG cannot perform RLM / BFD / RRM measurement relaxation unless it simultaneously meets the cell center determination criteria and the low mobility state determination criteria.

[0170] In step 3b, after determining to execute measurement relaxation, the terminal enters the corresponding measurement relaxation state, and continuously determines whether the low mobility state is met according to the determination period setting requirement of the low mobility state. If not met, it exits the measurement relaxation state. Additionally, the terminal further determines based on the current measurement results whether it is necessary to exit the measurement relaxation state because the cell center determination criteria are not met.

[0171] In step 4b, the terminal exits the measurement relaxation state and returns to step 2b for continuous determination.

[0172] Exemplarily, for the low mobility state determination criteria set based on the serving cell, for example, in the CA / DC scenario in the connected state, the measurement relaxation method includes the following steps 1c, 2c, 3c, and 4c.

[0173] In step 1c, the time duration T SearchDeltaP , threshold S SearchDeltaP , correlation parameters of the low mobility state determination criteria such as the determination period, and correlation parameters of the cell center determination criteria such as the threshold are received.

[0174] Optionally, the correlation parameters of the cell center determination criteria may not be set, or may be set implicitly. For example, the terminal determines whether it is necessary to determine whether the cell center determination criteria are met in a certain cell where RLM or BFD or RRM measurement within the CG is performed based on the indication information on whether the cell center determination criteria are valid. If determination is necessary, the terminal determines the correlation parameters of the cell center determination criteria by itself.

[0175] In the setting method based on the cell group, since the low-mobility state determination criterion may be set with correlation parameters in the setting of each serving cell, it is only effective for the current serving cell. Optionally, the set serving cell can only be an NR serving cell and cannot be an LTE serving cell.

[0176] Optionally, in each CG, the terminal determines whether measurement relaxation is possible according to the first or most recent serving cell in which the low-mobility state determination criterion is set. Optionally, the network-side device may be limited to setting the low-mobility state determination criterion only for cells that require RLM and / or BFD, that is, the terminal determines whether measurement relaxation is possible in the PCell, PSCell, and SCell that require BFD measurement within the CG.

[0177] In the serving cell where the low-mobility state determination criterion is set, the UE further determines whether a certain serving cell requires RLM / BFD measurement based on other information, and in the cells that require measurement, it determines whether RLM / BFD measurement relaxation is possible based on the cell center determination criterion. These cells that require RLM / BFD measurement include at least all PCells and PSCs, and also include some SCells that require BFD measurement.

[0178] When the terminal determines whether measurement relaxation is possible in the SCell that requires BFD measurement within the CG, for example, if it is set that measurement relaxation is only possible for one SCell in a certain frequency band, the terminal selects to perform measurement on this SCell and can relax the BFD measurement when the conditions are met. When the terminal performs BFD measurement on other SCells in this frequency band or SCells in other frequency bands, the terminal may consider that it cannot perform BFD measurement relaxation on other SCells in this frequency band or SCells in other frequency bands.

[0179] In step 2c, the terminal starts to determine whether to measure the serving cell based on the low mobility state determination criteria set by the network-side device in the corresponding serving cell, determines the low mobility state determination result, and determines the cell center determination result based on the cell center determination criteria. Specifically, refer to the foregoing embodiments.

[0180] When the network-side device is set such that the terminal needs to report the determination result to the network-side device, the terminal needs to report at least one of the low mobility state determination result, the cell center determination result, or whether to perform measurement relaxation to the network-side device in the corresponding CG.

[0181] Optionally, when the terminal determines that it can perform RLM / BFD / RRM measurement relaxation on the primary cell (PCell) or the primary secondary cell (PSCell) within the CG, the secondary cell (SCell) also performs RLM / BFD / RRM measurement relaxation.

[0182] Optionally, when a CG contains different cells in multiple frequency bands, the terminal determines whether the cells in the frequency band require RLM / BFD / RRM measurement relaxation based on the measurement results of the primary cell (PCell) or the primary secondary cell (PSCell) in the frequency band containing the primary cell (PCell) or the primary secondary cell (PSCell), and in the frequency band not containing the primary cell (PCell) or the primary secondary cell (PSCell), the terminal determines whether to perform RLM / BFD / RRM measurement relaxation based on the measurement results of the SCell.

[0183] Optionally, in the frequency band not containing the PCell or the PSCell, the terminal only determines whether it meets the cell center determination criteria, that is, whether it is at the cell center, based on the measurement results of the SCell, and further determines whether to perform RLM / BFD / RRM measurement relaxation based on the low mobility state determination result corresponding to the PCell or the PSCell in the same CG.

[0184] Optionally, when the determination result of the MCG indicates that RLM / BFD / RRM measurement relaxation can be performed, RLM / BFD / RRM measurement relaxation is performed for all CGs. When the determination result of only one or more SCGs indicates that RLM / BFD / RRM measurement relaxation can be performed, RLM / BFD / RRM measurement relaxation is performed only for the SCGs for which measurement relaxation is determined to be possible.

[0185] When the determination result of the MCG indicates that RLM / BFD / RRM measurement relaxation can be performed, RLM / BFD / RRM measurement relaxation is performed as long as the determination of the SCG meets the cell center determination criteria. When the determination result of the MCG indicates that RLM / BFD / RRM measurement relaxation cannot be performed, the SCG cannot perform RLM / BFD / RRM measurement relaxation unless it simultaneously meets the cell center determination criteria and the low mobility state determination criteria.

[0186] In step 3c, after determining to execute measurement relaxation, the terminal enters the corresponding measurement relaxation state and continuously determines whether it meets the low mobility state according to the determination period setting request for the low mobility state. If it does not meet the criteria, it exits the measurement relaxation state. Additionally, the terminal further determines based on the current measurement results whether it is necessary to exit the measurement relaxation state because it does not meet the cell center determination criteria.

[0187] In step 4c, the terminal exits the measurement relaxation state and returns to step 2c for continuous determination.

[0188] Figure 4 is a schematic flowchart (part 2) of the measurement relaxation method provided in the embodiment of the present application. As shown in Figures 3 and 4, the measurement relaxation method provided in this embodiment includes the following steps 201 and 202.

[0189] In step 201, the network-side device sets the low mobility state determination criteria for the terminal.

[0190] In step 202, the network-side device receives the first indication information from the terminal. The first indication information is for indicating whether the terminal performs measurement relaxation in the serving cell within each cell group among at least one cell group. Whether the terminal performs measurement relaxation is determined based on the low mobility state determination result and the cell center determination result in each cell group of the terminal. The low mobility state determination result and the cell center determination result of each cell group are determined by the terminal based on the measurement result, the low mobility state determination criterion, and the cell center determination criterion of each cell group respectively.

[0191] Optionally, the network-side device can set the low mobility state determination criterion based on the terminal, the serving cell, or the cell group. The terminal determines the low mobility state based on the set low mobility state determination criterion and the measurement result, determines whether it is at the cell center based on the measurement result of the cell group and the cell center determination criterion, and further determines whether to perform measurement relaxation in the serving cell within the cell group.

[0192] Here, there is no limiting relationship between step 201 and step 202.

[0193] Step 201 is similar to step 100 in FIG. 3. Optionally, it may further include step 103 in which the terminal reports to the network-side device whether the terminal performs measurement relaxation in the serving cell within each cell group.

[0194] The method of the network-side device and the method of the terminal side are similar in realization principle and technical effect, and the description is omitted here.

[0195] In the method of this embodiment, the terminal determines the low mobility state determination result and the cell center determination result in each cell group based on the measurement results of each cell group among at least one cell group, the low mobility state determination criterion, and the cell center determination criterion. Further, based on the low mobility state determination result and the cell center determination result of each cell group, it is determined whether measurement relaxation can be performed on the serving cell in each cell group, and then measurement relaxation is performed on the serving cell in each cell group respectively. Thereby, when multiple serving cells are set by the network-side device, the terminal can determine whether to perform measurement relaxation according to the actual situation of each cell group or each serving cell, and has relatively high flexibility in terms of the trade-off between communication performance and power saving performance.

[0196] Optionally, when the setting method of the low mobility state determination criterion is based on the terminal, the low mobility state determination result of the terminal in each cell group is whether the terminal determines based on the measurement result of the primary secondary cell (PSCell) in the NR secondary cell group (SCG) first set by the network-side device, or the low mobility state determination result of the terminal in each cell group is whether the terminal determines based on the measurement result of the primary cell (PCell) or the primary secondary cell (PSCell) of each cell group, or the low mobility state determination result of the terminal in each cell group is whether the terminal determines based on the measurement result of at least one serving cell in each cell group, and when the setting method of the low mobility state determination criterion is based on the cell group, the low mobility state determination result of the terminal in each cell group is whether the terminal determines based on the measurement result of the primary cell (PCell) or the primary secondary cell (PSCell) of each cell group, or The low mobility state determination results in each of the cell groups of the terminal are respectively determined by the terminal based on the measurement results of at least one serving cell in each of the cell groups.

[0197] Optionally, when the setting method of the cell center determination criterion is based on the terminal, the cell center determination results in each of the cell groups of the terminal are whether the terminal is determined based on the measurement results of the primary secondary cell (PSCell) in the NR secondary cell group (SCG) initially set by the network side device, or The cell center determination results in each of the cell groups of the terminal are respectively whether the terminal is determined based on the measurement results of the primary cell (PCell) or the primary secondary cell (PSCell) of each of the cell groups, or The cell center determination results in each of the cell groups of the terminal are respectively determined by the terminal based on the measurement results of at least one serving cell in each of the cell groups, When the setting method of the cell center determination criterion is based on the cell group, The cell center determination results in each of the cell groups of the terminal are respectively whether the terminal is determined based on the measurement results of the primary cell (PCell) or the primary secondary cell (PSCell) of each of the cell groups, or The cell center determination results in each of the cell groups of the terminal are respectively determined by the terminal based on the measurement results of at least one serving cell in each of the cell groups.

[0198] Optionally, when the cell group includes a cell in a first frequency band and a cell in a second frequency band, for the first frequency band where the primary cell (PCell) or the primary secondary cell (PSCell) exists, the low mobility state determination result of the terminal in the first frequency band is determined by the terminal based on the measurement results of the primary cell (PCell) or the primary secondary cell (PSCell), and For a second frequency band in which there is no primary cell PCell or primary secondary cell PSCell, the low mobility determination result of the terminal in the second frequency band is the low mobility state determination result of the terminal in the first frequency band.

[0199] Optionally, when the cell group includes a cell in the first frequency band and a cell in the second frequency band, for the first frequency band in which there is a primary cell PCell or a primary secondary cell PSCell, the cell center determination result of the terminal in the first frequency band is determined by the terminal based on the measurement result of the primary cell PCell or the primary secondary cell PSCell. For a second frequency band in which there is no primary cell PCell or primary secondary cell PSCell, the cell center determination result of the terminal in the second frequency band is determined by the terminal based on the measurement result of the secondary cell SCell in the second frequency band.

[0200] Optionally, when the setting method of the low mobility state determination criterion is based on the serving cell, the low mobility state determination result of the terminal in each cell group is determined by the terminal based on the measurement result of the first or most recent serving cell for which the low mobility determination criterion is set, or the low mobility state determination result of the terminal in each cell group is respectively determined by the terminal based on the measurement result of the primary cell PCell or the primary secondary cell PSCell of each cell group, or the low mobility state determination result of the terminal in each cell group is respectively determined by the terminal based on the measurement result of at least one serving cell in each cell group.

[0201] Optionally, when the setting method of the cell center determination criterion is based on the serving cell, The cell center determination result in each of the cell groups of the terminal is determined by the terminal based on the measurement result of the first or the most recent serving cell for which the cell center determination criterion is set, or The cell center determination result in each of the cell groups of the terminal is respectively determined by the terminal based on the measurement result of the primary cell (PCell) or the primary secondary cell (PSCell) of each of the cell groups, or The cell center determination result in each of the cell groups of the terminal is respectively determined by the terminal based on the measurement result of each serving cell within each of the cell groups.

[0202] Optionally, the terminal's execution of BFD measurement relaxation on the serving cell within the cell group is determined based on the low mobility state determination result of the terminal in the cell group and the cell center determination result of the terminal in the cell group. Here, the cell center determination result of the terminal in the cell group is determined based on the measurement result of the secondary cell (Scell) for the terminal to determine to perform beam failure detection (BFD) measurement.

[0203] Optionally, the method includes a step of the network-side device transmitting second indication information to the terminal, where the second indication information is for instructing that the cell center determination criterion for the serving cell within the cell group of the terminal becomes effective.

[0204] Optionally, the setting method of the cell center determination criterion is determined based on the setting method of the second indication information.

[0205] The specific realization process and technical effects in the above embodiments are similar to those in the method embodiments on the terminal side. Specifically, reference can be made to the detailed description in the embodiments on the terminal side, and the description is omitted here.

[0206] It should be noted that the entity executing the measurement relaxation method provided in the embodiments of the present application may be a measurement relaxation device or a processing module in the measurement relaxation device for executing the measurement relaxation method. In the embodiments of the present application, taking the measurement relaxation device executing the measurement relaxation method as an example, the measurement relaxation device provided in the embodiments of the present application will be described.

Further, the processing module determines whether it is possible to execute measurement relaxation in the serving cell within each of the cell groups respectively based on the low mobility state determination result and the cell center determination result of each of the cell groups, and then executes measurement relaxation in the serving cell within each of the cell groups respectively.
