Description

Technical Field

[0001] (Cross - reference to Related Applications) This application claims the priority of a Chinese patent application with the application number 202110904341.1 and the invention title "Method, Apparatus, Terminal, and Network - side Device for Determining a Low - Mobility State", which was filed on August 6, 2021, and all of it is incorporated herein by reference.

[0002] This application belongs to the field of communication technologies, and specifically relates to a method, apparatus, terminal, and network - side device for determining a low - mobility state.

Background Art

[0003] In a conventional mobile communication system, in order to save power consumption, a terminal, such as a Narrow Band Internet of Things (NB - IoT) terminal, does not need to measure adjacent cells of the same frequency or different frequencies under the condition that the measurement value of the serving cell meets the measurement relaxation criterion. When it is determined that the measurement relaxation criterion condition is met, it is generally necessary to determine whether the terminal is in a low - mobility state.

[0004] For a terminal in the idle state, to determine whether it is in a low - mobility state, it is only necessary to determine the low - mobility state based on the current registered cell. However, in other scenarios, such as a scenario supporting Carrier aggregation (CA) or Dual connectivity (DC), the terminal may be configured to be connected to multiple serving cells simultaneously, and at this time the terminal is in a connected state. Therefore, for those skilled in the art, it is necessary to realize a solution for determining whether the terminal is in a low - mobility state when multiple serving cells are configured for the terminal.

[0023] Hereinafter, the method for determining the low-mobility state according to the embodiments of the present application will be described in detail with reference to the drawings and several embodiments and their application scenarios.

[0024] The method for determining the low-mobility state according to the embodiments of the present application is applicable to a scenario where the terminal is in a connected state. When multiple serving cells are configured for the terminal, the terminal determines whether it is in a low-mobility state based on the measurement results of one of the serving cells. On the one hand, the processing overhead for the terminal to determine the low-mobility state is significantly reduced. On the other hand, since the determination results of multiple serving cells are different, the terminal will not cause a conflict in the processing logic.

[0025] FIG. 2 is one of the flowcharts of the method for determining the low-mobility state according to the embodiments of the present application. As shown in FIG. 2, the method for determining the low-mobility state according to this embodiment includes the following steps.

[0026] In step 101, if there are multiple serving cells configured in the terminal, the terminal acquires the measurement result of the first serving cell, and the first serving cell is one of the multiple serving cells.

[0027] Specifically, if there are multiple serving cells configured in the terminal, in order to reduce the processing complexity of the terminal, the terminal may determine whether the terminal is in a low mobility state based on the measurement result of the first serving cell among the multiple serving cells.

[0028] Optionally, the terminal may select one first serving cell based on the configuration of the network-side device. For example, the network-side device may indicate the serving cell or cell group for determining the low mobility state, or the network-side device may not explicitly indicate the serving cell or cell group for determining the low mobility state. For example, the terminal may select the Primary Cell (PCell) or Primary Secondary Cell (PSCell) among the multiple serving cells, or the terminal may select the first serving cell from the multiple serving cells based on a predetermined rule, such as selecting the serving cell with the highest priority from the multiple serving cells.

[0029] In step 102, the terminal determines that the terminal is in a low mobility state based on the measurement result of the first serving cell.

[0030] Specifically, the terminal determines whether the terminal is in a low mobility state or not based on the measurement result of the first serving cell. The low mobility state means that the terminal does not move or moves within a limited range.

[0031] For example, the measurement result of this first serving cell is compared with a certain measurement reference value. If the difference is relatively small, the terminal is in a low mobility state; if the difference is relatively large, the terminal is not in a low mobility state. Here, the initial value of the measurement reference value may be configured by the network-side device or determined by the terminal itself. Optionally, the measurement reference value may be updated based on the measurement result.

[0032] Optionally, in the special case of the low mobility state, it is the stationary state.

[0033] In the method of this embodiment, when multiple serving cells are configured for the terminal, the terminal determines that the terminal is in a low mobility state based on the measurement result of one first serving cell among the multiple serving cells. That is, when multiple serving cells are configured for the terminal, it realizes determining the low mobility state of the terminal, and based only on the measurement result of one serving cell, it determines whether this terminal is in a low mobility state. Therefore, the processing complexity is relatively low and the power consumption of the terminal is low.

[0034] In the embodiment of this application, this measurement result is the measurement result of at least one of the reference signals including the Synchronization Signal and PBCH block (SSB), the Channel State Information Reference Signal (CSI-RS) for tracking the time-frequency domain, the CSI-RS for measuring the channel state, and the CSI-RS for mobility measurement.

[0035] Optionally, the measurement result is the Reference Signal Received Power (RSRP), the Reference Signal Received Quality (RSRQ). including any one or a combination thereof of the Signal to Interference plus Noise Ratio (SINR).

[0036] Optionally, when the measurement result is a combination, it includes at least the Reference Signal Received Power (RSRP).

[0037] Optionally, the RSRP, RSRQ or SINR is the measurement result after smoothing filtering.

[0038] In the embodiments of the present application, the following steps may be further executed after step 102.

[0039] Based on the terminal being in a low mobility state, it is determined to perform measurement relaxation on the first serving cell, and the 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.

[0040] Specifically, when the terminal is in a low mobility state, measurement relaxation may be performed on the first serving cell, and optionally, measurement relaxation may also be performed on other serving cells configured by the terminal. The measurement relaxation can, for example, increase the measurement interval and reduce the power consumption of the terminal.

[0041] In the above embodiment, when the terminal is in a low mobility state, the terminal may relax the measurement on the serving cell, that is, the measurement requirement is reduced, and the power consumption of the terminal is relatively low.

[0042] In the embodiments of the present application, the first serving cell is determined based on the configuration method of the low mobility state determination criterion transmitted by the terminal from the network side device.

[0043] Here, the configuration method of the low mobility state determination criterion includes, for example, a configuration based on a terminal, a configuration based on a cell group, or a configuration based on a serving cell.

[0044] Specifically, the configuration based on a terminal means that the hierarchy of the configuration of the low mobility state determination criterion is at the terminal level, that is, this configuration is effective for all serving cells of all cell groups of the terminal. The configuration based on a cell group means that the hierarchy of the configuration of the low mobility state determination criterion is at the cell group level, that is, this configuration is effective for all serving cells of a specific cell group of the terminal. The configuration based on a serving cell means that the hierarchy of the configuration of the low mobility state determination criterion is at the serving cell level, that is, this configuration is effective for a certain serving cell of the terminal.

[0045] Specifically, the network-side device may configure the low mobility state determination criterion based on a terminal, a serving cell, or a cell group. In different configuration methods, since the selection method of the first serving cell for the terminal to determine the low mobility state may be different, the terminal needs to obtain the current configuration method of the low mobility state determination criterion from the network-side device. The terminal selects one first serving cell from a plurality of serving cells based on this configuration method.

[0046] As shown in FIG. 3, in step 100, the network-side device configures this low mobility state determination criterion for the terminal, determines one first serving cell based on this configuration method of the low mobility state determination criterion, and based on the measurement result of this first serving cell, determines that the terminal is in the low mobility state. Optionally, further execute step 103, and the terminal may report to the network-side device that the terminal is in the low mobility state.

[0047] Here, for the configuration method based on the terminal configuration, for the low mobility state determination criterion of this terminal configuration, it is applicable to any cell group. For a certain terminal, this low mobility state determination criterion may be configured, or this low mobility state determination criterion may not be configured.

[0048] Regarding the configuration method based on the cell group configuration, low mobility state determination criteria are respectively configured for different cell groups, and the parameter values of the relevant parameters of the low mobility state determination criteria for different cell group configurations may be the same or different. For a certain cell group, this low mobility state determination criteria may or may not be configured. If a certain cell group does not configure this low mobility state determination criteria, this cell group is not used to determine that the terminal is in the low mobility state.

[0049] Regarding the configuration method based on the serving cell configuration, low mobility state determination criteria are respectively configured for different serving cells. For a certain serving cell, this low mobility state determination criteria may or may not be configured. If a certain serving cell does not configure this low mobility state determination criteria, this serving cell is not used to determine that the terminal is in the low mobility state, that is, this serving cell is not used as the first serving cell.

[0050] In the above embodiment, the terminal may determine which serving cell among a plurality of serving cells is used as the first serving cell based on the configuration method of the low mobility state determination criteria transmitted from the network side device, and the processing complexity is relatively low.

[0051] In the embodiments of the present application, the first serving cell may be determined by the following multiple methods.

[0052] One method When the configuration method of the low mobility state determination criteria is based on the terminal configuration, When there is a New Radio (NR) Primary Cell (PCell), the first serving cell is the NR PCell. When there is no NR PCell, the first serving cell is the first Primary Secondary Cell (PSCell) configured by the network side.

[0053] Specifically, for the configuration method based on the terminal configuration, when there is a primary cell PCell of NR in multiple serving cells of the terminal, this PCell is used as the first serving cell, and based on the measurement result of this PCell, the low-mobility state of this terminal is determined, that is, it is determined whether the terminal is in the low-mobility state.

[0054] When there is no primary cell PCell of NR in multiple serving cells of the terminal, for example, the multiple serving cells are 4G serving cells, the first primary secondary cell PSCell configured by the network-side device in the multiple serving cells is used as the first serving cell, and based on the measurement result of this PSCell, the low-mobility state of this terminal is determined, that is, it is determined whether the terminal is in the low-mobility state.

[0055] Here, NR is a common name for the 5G air interface.

[0056] Another method When the configuration method of the low-mobility state determination criterion is based on the cell group configuration, the first serving cell is the primary cell PCell or the primary secondary cell PSCell in the target cell group.

[0057] Specifically, for the configuration method based on the cell group configuration, the first serving cell for determining whether the terminal is in the low-mobility state may be the primary cell PCell or the primary secondary cell PSCell in the target cell group, and based on the measurement result of this primary cell PCell or primary secondary cell PSCell, the low-mobility state of this terminal is determined, that is, it is determined whether the terminal is in the low-mobility state.

[0058] Here, the target cell group is one target cell group in the cell group where multiple serving cells are located. How to specifically select the target cell group will be described in detail in subsequent embodiments.

[0059] Another method When the configuration method of the low mobility state determination criterion is based on the serving cell configuration, The first serving cell is the only serving cell determined by the network-side device configuration to be in the low mobility state based on the cell measurement result, or, When the network-side device configures the low mobility state determination criterion for multiple serving cells, the following cases are included.

[0060] The first case: The first serving cell is the first or the most recent serving cell configured by the network-side device and determined to be in the low mobility state based on the cell measurement result, or, The second case: The first serving cell is the second serving cell among the target cell groups configured by the network-side device to determine the low mobility state, where the second serving cell is the only serving cell in the target cell group for which the low mobility state determination criterion is configured, or, The third case: The first serving cell is determined based on the priority corresponding to each serving cell configured by the network-side device.

[0061] Specifically, for the configuration method based on the serving cell configuration, the first serving cell may be the serving cell that determines whether the terminal is in the low mobility state based on the only cell measurement result configured by the network-side device, or, When the network-side device configures the low mobility state determination criterion in multiple serving cells, the terminal needs to determine, based on other configuration information of the network-side device, which serving cell to use to determine whether the terminal is in the low mobility state, that is, which serving cell to determine as the first serving cell.

[0062] Regarding the first case, the first serving cell may be the serving cell determined by the terminal to be in a low mobility state based on the cell measurement result of the first or the nearest one configured by the network side device. For example, the network side device may instruct that the low mobility state determination criteria are configured for serving cell 1, serving cell 2, and serving cell 3 respectively. For example, if the low mobility state determination criteria are configured for only one serving cell at a time, serving cell 1 is the serving cell for which the first low mobility state determination criteria are configured, and the nearest one is the serving cell for which the network side device has configured the low mobility state determination criteria most recently, for example, the serving cell corresponding to the most recent configuration in the current time interval.

[0063] Regarding the second case, the first serving cell is the second serving cell among the target cell group configured by the network side device for determining to be in a low mobility state. Here, this second serving cell is the serving cell for which the only low mobility state determination criteria in this target cell group are configured.

[0064] Regarding the third case, the first serving cell may be further determined based on the priority corresponding to each serving cell. For example, the serving cell with the highest priority among the serving cells for which the low mobility state determination criteria are configured is determined as this first serving cell, and the terminal determines whether the terminal is in a low mobility state based on the low mobility state determination criteria configured for this serving cell with the highest priority.

[0065] Optionally, for the third case, the serving cell for determining the low mobility state may be an SCell.

[0066] Optionally, the target cell group may be determined by the following multiple methods.

[0067] The target cell group is determined based on a target signaling message transmitted from a network-side device, or The target cell group is a cell group configured by a network-side device and having the first or the most recent or the only low-mobility state determination criterion configured therein, or The target cell group is determined based on the priority corresponding to each cell group configured by a network-side device.

[0068] Specifically, the target signaling message is, for example, an RRC establishment Setup or an RRC reconfiguration Reconfig signaling message transmitted from a network-side device. This target signaling message may indicate a cell group for determining a low-mobility state.

[0069] Here, the cell group having the most recent low-mobility state determination criterion configured therein refers to the cell group in which the network-side device configured the low-mobility state determination criterion most recently.

[0070] The target cell group may further be determined based on the priority corresponding to each cell group. For example, a cell group having the highest priority in a cell group in which a low-mobility state determination criterion is configured is determined as this target cell group.

[0071] The terminal determines whether the terminal is in a low-mobility state based on relevant parameters of the low-mobility state determination criterion configured in this target cell group. The relevant parameters include, for example, a time duration, a target threshold, a priority parameter of the cell group, or a priority parameter of a serving cell.

[0072] In the above embodiment, the terminal may select one first serving cell based on different configuration methods of the low-mobility state determination criterion, and thereby determine whether the terminal is in a low-mobility state based on the measurement result of this first serving cell, and the processing complexity is relatively low.

[0073] In an embodiment of the present application, the method for determining this low mobility state is that when it is determined that the terminal is in the low mobility state when the terminal is in the idle state, after entering the connected state, it further includes reporting to the network-side device that the terminal is in the low mobility state.

[0074] Specifically, when the terminal has performed correlation measurement on the frequency points of the primary cell (PCell), or the primary secondary cell (PSCell), or the secondary cell (SCell) based on the idle state, for example, in the DC scenario or the SCell scenario, this measurement may be an early measurement, and based on the low mobility state determination criterion in the idle state, if the terminal has already determined that it is in the low mobility state in the idle state, the fact that this terminal is in the low mobility state may be reused in the connected state, that is, it is determined that this terminal is also in the low mobility state in the connected state, and after entering the connected state, report to the network-side device that the terminal is in the low mobility state.

[0075] In the above embodiment, the result that the terminal is already in the determined low mobility state in the idle state is diverted to the connected state, and the terminal does not need to judge based on the measurement result, reducing unnecessary processing processes, further reducing the power consumption of the terminal, and saving processing time.

[0076] In an embodiment of the present application, step 102 may be realized in the following manner.

[0077] If the measurement result of at least one reference signal of the first serving cell meets the low mobility state determination criterion, it is determined that the terminal is in the low mobility state, or If the measurement results of all reference signals of the first serving cell all meet the low mobility state determination criterion, it is determined that the terminal is in the low mobility state, or When multiple reference signals of the first serving cell are synchronization signal blocks SSBs with different indexes or channel state information reference signals CSI-RS of different ports of the same type, the terminal determines that it is in a low-mobility state based on the average value or the maximum value of the measurement results of the multiple reference signals.

[0078] Optionally, this method for determining the low-mobility state is When the measurement results of all the reference signals of the first serving cell do not satisfy the low-mobility state determination criterion, the terminal determines that it is not in a low-mobility state, and When the measurement result of at least one reference signal of the first serving cell does not satisfy the low-mobility state determination criterion, it further includes that the terminal determines that it is not in a low-mobility state.

[0079] Specifically, when there are multiple reference signals for determining the low-mobility state, if the measurement result of any one of the reference signals satisfies the low-mobility state determination criterion, the terminal is in a low-mobility state. For example, the terminal has already been in a low-mobility state for a certain period of time, or the terminal was not in a low-mobility state before and enters a low-mobility state at this time. If the measurement results of all the reference signals cannot satisfy the low-mobility state determination criterion, the terminal determines that it is not in a low-mobility state. For example, the terminal has not been in a low-mobility state for a certain period of time, or the terminal was in a low-mobility state before and ends the low-mobility state at this time. When there are multiple reference signals for determining the low-mobility state, if the measurement results of all the reference signals satisfy the low-mobility state determination criterion, the terminal determines that it is in a low-mobility state. For example, the terminal has already been in a low-mobility state for a certain period of time, or the terminal determines that it was not in a low-mobility state before and enters a low-mobility state at this time. If the measurement result of any one of the reference signals cannot satisfy the low-mobility state determination criterion, the terminal determines that it is not in a low-mobility state. For example, the terminal has not been in a low-mobility state for a certain period of time, or the terminal was in a low-mobility state before and ends the low-mobility state at this time.

[0080] When there are multiple reference signals for determining the low-mobility state, and these reference signals are SSBs with different indexes or CSI-RSs of different ports of the same type, the terminal determines whether the terminal is in the low-mobility state based on the average value or the maximum value of the measurement results of the multiple reference signals. For example, calculate the average value of the measurement results of the multiple reference signals, compare this average value with the measurement reference value. If the difference is relatively small, it is determined that the terminal is in the low-mobility state; otherwise, it is not in the low-mobility state.

[0081] In the above embodiment, when there are multiple reference signals, it realizes how the terminal determines that it is in the low-mobility state, and the realization process is simple.

[0082] In the embodiments of the present application, the low-mobility state determination criterion is the difference between the measurement reference value and the correction value of the measurement result, which is below the target threshold. The measurement reference value is obtained based on the cell measurement result when the terminal is in the connected state or the measurement reference value when the terminal is in the idle state.

[0083] Optionally, the terminal determines whether the terminal is in the low-mobility state based on the measurement reference value Low_Mob_REF and the measurement result. When the difference between the measurement result Low_Mob_Meas of the terminal and Low_Mob_REF is below the target threshold, the terminal is in the low-mobility state.

[0084] (Low_Mob_REF - Low_Mob_Meas) < S SearchDeltaP Judge whether it is satisfied, where S SearchDeltaP may be the target threshold of the network configuration. If it is satisfied, the terminal is in the low-mobility state; if it is not satisfied, the terminal is not in the low-mobility state. Here, Low_Mob_REF is the measurement reference value.

[0085] Optionally, the terminal may determine whether it is necessary to update Low_Mob_REF based on the measurement results in the connected state, and when one or more of the following three conditions are met, set Low_Mob_REF = Low_Mob_Meas.

[0086] a. The UE has just entered the current first serving cell by cell selection or cell reselection, that is, this measurement is the first measurement of the terminal in the current first serving cell. b. Low_Mob_Meas < Low_Mob_REF c. The terminal has not been able to meet the low mobility state determination criteria for a certain period of time (T SearchDeltaP ), and the timer duration T SearchDeltaP may be configured by the network.

[0087] Optionally, if the low mobility criteria are also configured in the idle state and can be applied to the connected state, the measurement reference value in the idle state can also be applied to the connected state, that is, determine Low_Mob_REF based on the measurement reference value Srxlev_Ref in the idle state.

[0088] Optionally, the initial Low_Mob_REF may be configured by the network-side device, or may be determined based on the cell measurement results when the terminal is in the connected state, or the measurement reference value when the terminal is in the idle state.

[0089] Exemplarily, for the low mobility state determination criteria based on the terminal configuration, for example, in the CA / DC scenario in the connected state, this low mobility state determination method includes the following steps.

[0090] Step 1a: Receive the relevant parameters of the low mobility state determination criteria configured by the network-side device.

[0091] The relevant parameters are, for example, the duration T SearchDeltaP , the target threshold S SearchDeltaPIt includes. The configuration of this low-mobility state determination criterion may be enabled for all CGs. For example, in a situation where the terminal can search for NR system information block (SIB), that is, when there is an NR primary cell (PCell), this low-mobility state determination criterion may be directly configured in SIB2. In a situation where the terminal cannot search for NR SIB, that is, when there is no NR primary cell (PCell), this low-mobility state determination criterion is given in a certain signaling (such as radio resource control (RRC) signaling) loaded by the NR secondary cell group (SCG). At this time, the network-side device may configure this low-mobility state determination criterion only in the signaling that initially constitutes the NR SCG, and the terminal determines whether the terminal is in a low-mobility state based on the PSCell in the NR SCG. When the network-side device configures early measurement for the frequency point corresponding to the NR SCG, it may also configure the corresponding low-mobility criterion.

[0092] Step 2a: The terminal determines whether the terminal is in a low-mobility state based on the measurement result in the connected state and the measurement reference value Low_Mob_REF.

[0093] Step 3a: If the terminal is in a low-mobility state, the terminal enters the RLM / BFD / RRM measurement relaxation state.

[0094] Exemplarily, for the low-mobility state determination criterion based on the cell group configuration, for example, in the connected state CA / DC scenario, the determination method of this low-mobility state includes the following steps.

[0095] Step 1b: Receive the related parameters of the low-mobility state determination criterion configured by the network-side device.

[0096] The related parameters are, for example, the time duration T SearchDeltaP , the target threshold S SearchDeltaPIt includes. This low mobility state determination criterion is independently configured for each cell group CG. When related parameters are configured for multiple CGs, that is, when low mobility state determination criteria are configured for multiple CGs, the terminal determines the CG for which the terminal is determined to be in the low mobility state based on other configurations of the network-side device. For example, the network-side device may explicitly indicate the CG for which the terminal is determined to be in the low mobility state in the RRC establishment Setup message or the RRC reconfiguration Reconfig message. Also, for example, the terminal may use the CG in which the first or the most recent or the only low mobility state determination criterion configured by the network-side device is configured to determine that the terminal is in the low mobility state. Also, for example, this main parameter includes the priority configuration of the cell group. For example, the terminal determines the parameter for determining the low mobility state based on the low mobility state determination criterion configured for the CG with the highest priority, and further determines whether the terminal is in the low mobility state. At this time, the first serving cell for determining that the terminal is in the low mobility state may be the Pcell or PSCell in this CG.

[0097] Step 2b: The terminal determines whether the terminal is in the low mobility state based on the measurement result in the connected state and the measurement reference value Low_Mob_REF.

[0098] Step 3b: If the terminal is in the low mobility state, the terminal enters the RLM / BFD / RRM measurement relaxation state.

[0099] Exemplarily, for the low mobility state determination criterion based on the serving cell configuration, for example, in the connected state CA / DC scenario, this method for determining the low mobility state includes the following steps.

[0100] Step 1c: Receive the related parameters of the low mobility state determination criterion configured by the network-side device.

[0101] The related parameters are, for example, the time duration T SearchDeltaP and the target threshold S SearchDeltaPIt includes. The low mobility state determination criteria are independently configured in each serving cell. Optionally, the network side device configures the low mobility state determination criteria only for one of the serving cells. Optionally, the network side device configures the low mobility state determination criteria for all of the multiple serving cells, and the terminal needs to determine the serving cell for which the terminal determines that it is in the low mobility state based on other configuration information of the network side device. For example, the terminal can determine whether it is in the low mobility state in the first or the most recent serving cell that can determine whether it is in the low mobility state based on the measurement result configured by the network side device, that is, determine whether it is in the low mobility state based on the first or the most recent measurement result configured by the network side device, and use the first or the most recent serving cell that can determine whether it is in the low mobility state based on the measurement result configured by the network side device as the first serving cell. Also for example, the terminal determines a target cell group for determining that it is in the low mobility state based on the network side device configuration, selects the serving cell in which the low mobility determination criteria are configured within this target cell group to determine whether the terminal is in the low mobility state, and there is only one serving cell in this target cell group in which the low mobility state determination criteria are configured. Here, the method for determining the target cell group can refer to the above embodiments. Also for example, this main parameter further includes a cell priority configuration. For example, the terminal determines relevant parameters based on the low mobility state determination criteria configured in the serving cell with the highest priority, and further determines whether the terminal is in the low mobility state. At this time, the serving cell with the highest priority may be an SCell.

[0102] Step 2c: The terminal determines whether the terminal is in the low mobility state based on the measurement result in the connected state and the measurement reference value Low_Mob_REF.

[0103] Step 3c: If the terminal is in the low mobility state, the terminal enters the RLM / BFD / RRM measurement relaxation state.

[0104] FIG. 4 is a second flowchart of a method for determining a low mobility state according to an embodiment of the present application. As shown in FIG. 4, the method for determining a low mobility state according to this embodiment includes the following steps.

[0105] In step 201, the network-side device configures a low mobility state determination criterion for the terminal.

[0106] In step 202, the network-side device receives first indication information from the terminal. The first indication information is used to indicate that the terminal is in a low mobility state. The low mobility state is determined based on the measurement result of the first serving cell of the terminal and the low mobility state determination criterion. The first serving cell is one of a plurality of serving cells configured for the terminal.

[0107] Optionally, the network-side device may configure a low mobility state determination criterion based on the terminal, the serving cell, or the cell group. The terminal needs to be based on the low mobility state determination criterion when determining the low mobility state. The terminal selects one first serving cell from a plurality of serving cells, and based on the measurement result of this first serving cell and the low mobility state determination criterion, determines whether this terminal is in a low mobility state. For example, it is determined whether the measurement result of this first serving cell meets this low mobility state determination criterion. If it is met, it is determined that this terminal is in a low mobility state. If it is not met, it is determined that this terminal is not in a low mobility state.

[0108] In the method of this embodiment, when a plurality of serving cells are configured for the terminal, the terminal determines that the terminal is in a low mobility state based on the measurement result of one first serving cell among the plurality of serving cells and reports it to the network-side device. That is, when a plurality of serving cells are configured for the terminal, the low mobility state of the terminal is determined, and based only on the measurement result of one serving cell, it is determined whether this terminal is in a low mobility state. Therefore, the processing complexity is relatively low, and the power consumption of the terminal is low.

[0109] Optionally, when the configuration method of the low mobility state determination criterion is based on the terminal configuration, when there is a New Radio (NR) Primary Cell (PCell), the first serving cell is the NR PCell, when the NR PCell does not exist, the first serving cell is the first Primary Secondary Cell (PSCell) configured by the network side.

[0110] Optionally, when the configuration method of the low mobility state determination criterion is based on the cell group configuration, the first serving cell is the Primary Cell (PCell) or the Primary Secondary Cell (PSCell) in the target cell group.

[0111] Optionally, when the configuration method of the low mobility state determination criterion is based on the serving cell configuration, the first serving cell is the only serving cell determined by the network side device configuration to be in the low mobility state based on the cell measurement results, or the first serving cell is the first or the most recent serving cell configured by the network side device and determined to be in the low mobility state based on the cell measurement results, or the first serving cell is the second serving cell in the target cell group configured by the network side device for determining the low mobility state, where the second serving cell is a serving cell configured to be determined to be in the low mobility state based on the only cell measurement result in the target cell group, or the first serving cell is determined based on the priority corresponding to each serving cell configured by the network side device.

[0112] Optionally, the target cell group is determined based on a target signaling message sent from the network side device, or The target cell group is a cell group configured by a network-side device and having the first or the nearest or the only low-mobility state determination criterion configured, or, The target cell group is determined based on the priority corresponding to each cell group configured by a network-side device.

[0113] Optionally, this method further includes the following steps: The network-side device receives second indication information from the terminal. The second indication information is sent when the terminal enters a connected state and is used to indicate that the terminal is in a low-mobility state. The low-mobility state indicated by this second indication information is determined by the terminal in an idle state.

[0114] Optionally, when the measurement result of at least one reference signal of the first serving cell meets the low-mobility state determination criterion, the terminal is in a low-mobility state. When the measurement results of all reference signals of the first serving cell all meet the low-mobility state determination criterion, the terminal is in a low-mobility state. When the measurement results of all reference signals of the first serving cell do not meet the low-mobility state determination criterion, the terminal is not in a low-mobility state. When the measurement result of at least one reference signal of the first serving cell does not meet the low-mobility state determination criterion, the terminal is not in a low-mobility state. When a plurality of reference signals of the first serving cell are synchronization signal blocks SSBs with different indexes or channel state information reference signals CSI-RS of different ports of the same type, the low-mobility state of the terminal is determined based on the average value or the maximum value of the measurement results of the plurality of reference signals.

[0115] Optionally, the low-mobility state determination criterion is the difference between the measurement reference value and the measurement result, and is less than or equal to a first threshold value. The measurement reference value is obtained based on the cell measurement result or is the measurement reference value when the terminal is in the idle state.

[0116] The specific implementation process and technical effects in the above embodiment are similar to those of the terminal-side example. Specifically, reference can be made to the detailed description in the terminal-side example, and no further explanation will be given here.

For example, it may be at least one magnetic disk memory device, a flash memory device, or other non-volatile solid-state memory devices.

[0147] The processor 1010 may include one or more processing units. Optionally, the processor 1010 may integrate an application processor and a modem processor. Here, the application processor mainly processes an operating system, a user interface, and application programs or instructions, etc., and the modem processor mainly processes wireless communications, for example, a baseband processor. As can be understood, the above modem processor may not be integrated into the processor 1010.

[0148] Here, when a plurality of serving cells are configured in the terminal, the processor 1010 is used to obtain the measurement result of the first serving cell, and the first serving cell is one of the plurality of serving cells. Based on the measurement result, the terminal determines that the terminal is in a low mobility state.

[0149] In this embodiment, when a plurality of serving cells are configured in the terminal, the processor of the terminal determines that the terminal is in a low mobility state based on the measurement result of a first serving cell among the plurality of serving cells, that is, when a plurality of serving cells are configured in the terminal, the low mobility state of the terminal is determined, and only based on the measurement result of one serving cell, it is determined whether this terminal is in a low mobility state. Therefore, the processing complexity is relatively low and the power consumption of the terminal is low.

[0150] Optionally, the first serving cell is determined based on the configuration method of the low mobility state determination criterion transmitted by the terminal from the network side device.

[0151] In the above embodiment, the terminal may determine which serving cell among the plurality of serving cells is used as the first serving cell based on the configuration method of the low mobility state determination criterion transmitted by the network side device, and the processing complexity is relatively low.

[0152] Optionally, when the configuration method of the low mobility state determination criterion is based on the terminal configuration, when there is a New Radio (NR) Primary Cell (PCell), the first serving cell is the NR PCell, when the NR PCell does not exist, the first serving cell is the first Primary Secondary Cell (PSCell) configured by the network side device, or when the configuration method of the low mobility state determination criterion is based on the cell group configuration, the first serving cell is the Primary Cell (PCell) or the Primary Secondary Cell (PSCell) in the target cell group, or when the configuration method of the low mobility state determination criterion is based on the serving cell configuration, the first serving cell is the only serving cell determined by the network side device configuration to be in a low mobility state based on the cell measurement result, or The first serving cell is the serving cell determined to be in a low mobility state based on the cell measurement result of the first or the most recent one, which is configured by network-side equipment, or The first serving cell is the second serving cell among the target cell groups determined to be in a low mobility state, which is configured by network-side equipment. Here, the second serving cell is the serving cell in which the only low mobility state determination criterion in the target cell group is configured, or The first serving cell is determined based on the priority corresponding to each serving cell configured by network-side equipment.

[0153] Optionally, the target cell group is determined based on the target signaling message sent from network-side equipment, or The target cell group is the cell group configured by network-side equipment, in which the first or the most recent one or the only low mobility state determination criterion is configured, or The target cell group is determined based on the priority corresponding to each cell group configured by network-side equipment.

[0154] In the above embodiment, the terminal may select one first serving cell based on different configuration methods of the low mobility state determination criterion, and thereby determine whether the terminal is in a low mobility state based on the measurement result of this first serving cell, and the processing complexity is relatively low.

[0155] Optionally, the processor 1010 is further When it is determined that the terminal is in a low mobility state when the terminal is in an idle state, it is used to report to the network-side equipment that the terminal is in a low mobility state after entering the connected state.

[0156] In the above embodiment, the result that the terminal is already in the low mobility state determined in the idle state is diverted to the connected state, and the terminal does not need to judge based on the measurement result, reducing unnecessary processing processes, further reducing the power consumption of the terminal, and saving the processing time.

[0157] Optionally, the processor 1010 specifically When the measurement result of at least one reference signal of the first serving cell satisfies the low mobility state determination criterion, determining that the terminal is in the low mobility state; When the measurement results of all reference signals of the first serving cell all satisfy the low mobility state determination criterion, determining that the terminal is in the low mobility state; When a plurality of reference signals of the first serving cell are synchronization signal blocks SSBs with different indexes or channel state information reference signals CSI-RS of different ports of the same type, it is used to determine that the terminal is in the low mobility state based on the average value or the maximum value of the measurement results of the plurality of reference signals.

[0158] Optionally, the processor 1010 further When the measurement results of all reference signals of the first serving cell do not all satisfy the low mobility state determination criterion, determining that the terminal is not in the low mobility state; When the measurement result of at least one reference signal of the first serving cell does not satisfy the low mobility state determination criterion, it is used to determine that the terminal is not in the low mobility state.

[0159] In the above embodiment, when there are a plurality of reference signals, how to determine that the terminal is in the low mobility state is realized, and the realization process is simple.
