Abstract
Description
Technical Field
[0001] The present application relates to the field of communication technology, and in particular to a measurement method, a configuration method, a communication device, and a computer-readable storage medium. Background Art
[0002] In the New Radio (NR) system, the terminal measures the synchronization signal (Synchronization Signal) / Physical Broadcast Channel (PBCH) block (collectively referred to as the synchronization signal block (SSB) in this article) sent by the cell to achieve cell measurement. In order to reduce the measurement power consumption of the terminal, the NR system introduces the synchronization signal block measurement timing configuration (SS / PBCH blockMeasurement Timing Configuration, SMTC). SMTC is configured by the base station of the serving cell, and the terminal performs cell measurement according to SMTC.
[0003] At present, continuous switching solutions have also been introduced in the NR system, such as Layer 1 / Layer 2 Triggered Mobility (L1 / L2-Triggered Mobility, LMT), and another example, continuous conditional primary and secondary cells (Primary SCG Cell, PSCell) update (Conditional PSCell Change, CPC). In the LMT scenario, the network configures multiple candidate cells. After the terminal switches to the target cell, the terminal continues to retain other candidate cells for subsequent switching. In the continuous CPC scenario, the network configures multiple candidate PSCells and corresponding PSCell update execution conditions for the terminal. The terminal evaluates the candidate PSCells. If the update execution conditions are met, it accesses the PSCell that meets the conditions. After the terminal accesses the new PSCell, the terminal continues to retain other candidate PSCells for subsequent CPC.

[0046] Compared with the prior art, the technical solution of the embodiment of the present application has the following beneficial effects:
[0047] In the scheme of the embodiment of the present application, after the terminal accesses the target cell, the terminal measures the SSB on the first frequency according to the target SMTC corresponding to the target cell. With such a scheme, the terminal always uses the SMTC corresponding to the accessed target cell to perform cell measurement, which is conducive to accurately determining the timing of performing SSB measurement on the first frequency in the target cell, and avoiding the problem of missing measurements when performing cell measurement on the first frequency in the target cell.
[0048] Alternatively, after accessing the target cell, the terminal measures the SSB on the first frequency according to the absolute SMTC corresponding to the target cell. The absolute SMTC is based on absolute time. By adopting such a solution, the SMTC can be decoupled from the timing reference of the cell. The SSB measurement timing determined by the terminal according to the absolute SMTC is also an absolute time and is not affected by the timing reference of the target cell accessed. Therefore, it is helpful to determine the timing of SSB measurement on the first frequency in the target cell, and avoid the problem of missed measurement when performing cell measurement on the first frequency in the target cell.
[0049] Further, in the solution of the embodiment of the present application, the network device configures multiple SMTCs corresponding to the first frequency to the terminal, and the multiple SMTCs are respectively used to measure the SSB on the first frequency after accessing different target cells. With such a solution, the network device configures multiple SMTCs corresponding to the frequency at one time, so that the terminal can select the appropriate SMTC for cell measurement according to the target cell accessed during the continuous switching process, which is conducive to simplifying the complexity of the terminal determining the target SMTC.
[0050] Further, in the solution of the embodiment of the present application, the network device indicates to the terminal the offset between the timing reference of the target cell and the timing reference based on which the SMTC corresponding to the first frequency is based, and the terminal determines the target SMTC according to the timing offset. Adopting such a solution is conducive to reducing signaling overhead while enabling the terminal to determine the target SMTC. BRIEF DESCRIPTION OF THE DRAWINGS

[0065] The network device in the embodiment of the present application may also be referred to as an access network device, for example, a base station (BS for short) (also referred to as a base station device), which is a device deployed in a radio access network (RAN) to provide wireless communication functions. For example, the equipment that provides base station functions in the second-generation (2G) network includes a base transceiver station (BTS), the equipment that provides base station functions in the third-generation (3G) network includes a node B, and the equipment that provides base station functions in the fourth-generation (4G) network includes an evolved node B (eNB).

The network devices in the embodiments of the present application also include devices that provide base station functions in future new communication systems, etc.
[0066] As described in the background art, the current SMTC mechanism is not well suited for continuous handover scenarios, and a more optimized SMTC mechanism is urgently needed to meet the cell measurement requirements in continuous handover scenarios.
[0067] Reference Figure 1 , Figure 1 It is a timing diagram of multiple cells. Figure 1 The timing of cell 1, cell 2 and cell 3 is shown.
[0068] Assume that the current serving cell is cell 1, and the base station configures multiple candidate cells for the terminal, including cell 2 and cell 3, where the frequency corresponding to cell 2 is F1, that is, cell 2 is located on frequency F1 and has a certain bandwidth. In addition, the base station also configures the SMTC corresponding to F1. When cell 1 is used as the serving cell, the terminal determines the timing of measuring the SSB of cell 2 as the position of time slot 5 and time slot 6 according to the SMTC corresponding to F1.
[0069] After the terminal switches to access cell 3, the terminal should measure the SSB on cell 2 at the positions of time slots 2 and 3 on cell 3. However, in the prior art, in a cell switching scenario, SMTC is based on the timing reference of the source cell. If the original SMTC is still used, the measurement timing of SSB on cell 2 will be incorrectly determined to be time slots 5 and 6. Measuring cell 2 at time slots 5 and 6 of cell 3 will result in missed measurements.
[0070] In view of this, an embodiment of the present application provides a measurement method. In the solution of the embodiment of the present application, after accessing the target cell, the terminal measures the SSB on the first frequency according to the target SMTC or absolute SMTC corresponding to the target cell. Adopting such a solution is conducive to accurately determining the timing of SSB measurement on the first frequency in the target cell, and avoiding the problem of missing measurements when performing cell measurement on the first frequency in the target cell.
[0071] It should be noted that the solution provided in the embodiment of the present application can be applied to a single connection scenario, that is, a single base station provides services for the terminal; or, the method provided in the embodiment of the present application can also be applied to a multi-radio dual connection (MultiRadio Dual Connectivity, referred to as MR-DC) scenario. Specifically, the primary base station and the secondary base station provide services to the terminal at the same time. The embodiment of the present application does not limit the type of dual connection, and the dual connection can be LTE dual connection, LTE and NR dual connection, NR dual connection, etc. For the dual connection of LTE and NR, it can include EN-DC (E-UTRAN NR Dual Connectivity, that is, the LTE base station is used as the primary base station of the UE, and the NR base station is used as the secondary base station of the UE), NE-DC (NR E-UTRAN Dual Connectivity, that is, the NR base station is used as the primary base station of the UE, and the LTE base station is used as the secondary base station of the UE), NR-DC (NRNR Dual Connectivity, that is, the primary base station and the secondary base station of the UE are both NR base stations), NGEN-DC (that is, the LTE base station connected to the 5G core network is used as the primary base station of the UE, and the NR base station is used as the secondary base station of the UE), etc.
[0072] It should be noted that the solution provided in the embodiment of the present application can also be applied to scenarios in which more base stations provide services to terminals in the future, and this embodiment does not limit this.
[0073] In order to make the above-mentioned purposes, features and beneficial effects of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings.
[0074] Reference Figure 2 , Figure 2 It is a flow chart of a measurement method in an embodiment of the present application. Figure 2 The illustrated measurement method can be applied to a terminal. Figure 2 The illustrated measuring method may include step S21 .
[0075] Step S21: After accessing the target cell, measure the SSB on the first frequency based on the target SMTC corresponding to the target cell.
[0076] Specifically, in the scenario of continuous switching, after the terminal accesses the target cell, the target SMTC is used to measure the SSB on the first frequency. The target SMTC refers to the SMTC corresponding to the target cell, and the target SMTC is based on the timing reference of the target cell. The first frequency can be any frequency to be measured.
[0077] It should be noted that the correspondence between the cell and the SMTC in the embodiment of the present application may refer to the timing reference of the SMTC based on the cell. It can be understood by those skilled in the art that the SMTC may include an offset parameter and a period parameter. In the solution of the embodiment of the present application, the offset parameter in the SMTC corresponding to the cell may be determined based on the timing reference of the cell.
[0078] Specifically, the target SMTC may include parameters such as an offset parameter and a periodicity, and the offset parameter in the target SMTC may be set according to the timing reference of the target cell. The terminal can determine the SSB measurement timing on the first frequency based on the offset parameter and the periodicity parameter in the target SMTC, wherein the determined SSB measurement timing is based on the timing reference of the target cell. In other words, the SSB measurement timing determined according to the target SMTC is the time domain position on the target cell. For example, time slot n is determined based on the offset parameter and the periodicity parameter, and time slot n is time slot n on the target cell.
[0079] Further, the terminal measures the cell on the first frequency at the SSB measurement opportunity determined based on the target SMTC. Exemplarily, the terminal may measure the candidate cell and / or neighboring cell on the first frequency at the SSB measurement opportunity determined based on the target SMTC.
[0080] Afterwards, if the terminal performs handover and accesses a new target cell, the terminal may measure the SSB on the first frequency based on the SMTC corresponding to the new target cell, wherein the SMTC corresponding to the new target cell is based on the timing reference of the new target cell.
[0081] It should be noted that in the scheme of the embodiment of the present application, the target SMTC may be for a specific frequency. If the terminal needs to measure a cell (for example, a neighboring cell or a candidate cell) on a certain frequency (such as the first frequency), the target SMTC is the SMTC used to measure the SSB on the frequency after the terminal accesses the target cell. If the terminal needs to measure cells on multiple frequencies, there are multiple target SMTCs, and the multiple target SMTCs are respectively for multiple frequencies that need to be measured. The multiple target SMTCs can be used to measure the SSBs on multiple frequencies after the terminal accesses the target cell, and the configurations of the multiple target SMTCs may be the same or different.
[0082] Exemplarily, after accessing the target cell, the terminal can measure the SSB on the first frequency based on the first target SMTC, and measure the SSB on the second frequency based on the second target SMTC. The first frequency and the second frequency are different, and the first target SMTC and the second target SMTC are both SMTCs corresponding to the target cell, but are applied to measurements of cells at different frequencies. The embodiment of the present application only describes the target SMTC, absolute SMTC, etc. using the first frequency as an example, but the method provided in the embodiment of the present application can be applied to measurements on multiple frequencies.
[0083] In one embodiment of the present application, the cell may refer to a primary cell (PCell). Specifically, after accessing the target PCell, the terminal may measure the SSB on the first frequency based on the SMTC corresponding to the target PCell.
[0084] In another embodiment of the present application, the cell may refer to a PSCell. Specifically, after accessing the target PSCell, the terminal may measure the SSB on the first frequency based on the SMTC corresponding to the target PSCell. For example, the terminal may measure the SSB on the first frequency (for example, the SSB of the candidate PSCell) based on the SMTC corresponding to the target PSCell.
[0085] From the above, the solution provided by the embodiment of the present application can be applied to the scenario of continuous switching. Whenever the terminal performs switching to access the target cell, for the SSB on the first frequency, the terminal always measures the SMTC corresponding to the accessed target cell. Adopting such a solution is conducive to accurately determining the timing of SSB measurement on the first frequency in the target cell, avoiding measurement failures, and thus ensuring the smooth implementation of continuous switching.
[0086] The specific method for determining the target SMTC can be referred to the specific description below and will not be repeated here.
[0087] Reference Figure 3 , Figure 3 It is a signaling interaction diagram of the first configuration method in an embodiment of the present application. Figure 3 The illustrated method may include step S31 .
[0088] Step S31: the network device sends SMTC information corresponding to the first frequency to the terminal, where the SMTC information is at least used to determine a target SMTC corresponding to a target cell.
[0089] In one embodiment of the present application, the SMTC information may include: first indication information, the first indication information may be used to indicate a timing offset, and the timing offset may refer to an offset between timing references of different cells. Specifically, the timing offset may refer to an offset between a timing reference of a target cell and a timing reference on which the SMTC corresponding to the first frequency is based.
[0090] Specifically, before step S31, the network device may configure the SMTC corresponding to the first frequency to the terminal, and the SMTC corresponding to the first frequency may be recorded as the reference SMTC. More specifically, the network device configures the reference SMTC with the service cell accessed by the terminal as the reference cell. In other words, the reference cell is the service cell accessed by the terminal when the network device configures the reference SMTC. That is, the reference SMTC is based on the timing reference of the reference cell.
[0091] Therefore, the timing offset may also refer to the offset between the timing reference of the target cell and the reference cell. In step S31, the network device may configure or indicate the timing offset to the terminal. Furthermore, the terminal may adjust the reference SMTC according to the timing offset to obtain the target SMTC. Alternatively, after accessing the target cell, the terminal may first determine a reference measurement timing on the first frequency based on the reference SMTC, and then adjust the reference measurement timing based on the timing offset to obtain the adjusted measurement timing, and measure the SSB on the first frequency at the adjusted measurement timing.
[0092] In a specific implementation, step S31 may be performed during the handover process. That is, in a continuous handover scenario, during each handover process, after determining the target cell for this handover, the network device may indicate the timing offset to the terminal. Alternatively, step S31 may be performed after accessing the target cell. That is, after each access to the target cell, the network device may indicate the timing offset to the terminal. For example, the timing offset may be indicated to the terminal via Radio Resource Control (RRC) signaling.
[0093] In other embodiments, the above timing offset may be determined by the terminal. Specifically, the terminal may record the timing reference of the reference cell, and after accessing the target cell, the terminal may record the timing reference of the target cell. Further, the terminal may determine the timing offset based on the timing reference of the target cell and the timing reference of the reference cell.
[0094] In one possible implementation, the above-mentioned timing offset may refer to the offset between the timing reference of the target cell and the timing reference of the source cell. In other words, the source cell may be the above-mentioned reference cell. That is to say, the SMTC corresponding to the first frequency is configured during the period when the source cell is a service cell. Furthermore, after receiving the first indication information, the terminal may adjust the SMTC corresponding to the first frequency based on the timing offset to obtain the target SMTC. Alternatively, after accessing the target cell, the terminal may determine the timing offset based on the timing reference of the target cell and the timing reference of the source cell, and then determine the target SMTC based on the timing offset and the SMTC corresponding to the first frequency.
[0095] In another embodiment of the present application, the SMTC information may include multiple SMTCs corresponding to the first frequency, and the multiple SMTCs corresponding to the first frequency are respectively used to measure the SSB on the first frequency after accessing different target cells. Among them, the information used to configure the multiple SMTCs corresponding to the first frequency can also be referred to as "first configuration information".
[0096] After step S31, the terminal may determine a target SMTC from a plurality of SMTCs corresponding to the first frequency based on the accessed target cell, and measure the SSB on the first frequency based on the target SMTC. Exemplarily, the target SMTC in step S21 may be selected from a plurality of SMTCs corresponding to the first frequency.
[0097] That is, for the first frequency, the network device may configure SMTCs corresponding to multiple cells, where the multiple cells are cells that may be accessed in the future. If the target cell is one of the multiple cells, the terminal may use the SMTC corresponding to the cell as the target SMTC.
[0098] For example, for SSB measurement on frequency F1, the network device configures SMTCs corresponding to multiple cells (Cell1, Cell2, Cell3, Cell4): F1, [SMTC1, Cell1], [SMTC2, Cell2], [SMTC3, Cell3], [SMTC4, Cell4]. Based on the above configuration, if the terminal accesses one of the multiple cells, the terminal can use the SMTC corresponding to the cell to measure the SSB on F1. For example, when the terminal accesses the target cell Cell3, the SMTC3 corresponding to the Cell3 is used as the SMTC for measuring the SSB on F1.
[0099] In another embodiment of the present application, the SMTC information may include: a first SMTC corresponding to the first cell and an offset between the timing reference of one or more second cells and the timing reference of the first cell, wherein the first cell and the second cell are cells that the terminal may access, the second cell and the first cell are different cells, and the first SMTC is used to measure the SSB on the first frequency after accessing the first cell. Specifically, the first SMTC is based on the timing reference of the first cell. Exemplarily, the first cell may be the above-mentioned reference cell, and the first SMTC may be the above-mentioned reference SMTC.
[0100] Specifically, for the first frequency, the network device can configure the SMTC corresponding to a cell (such as the first cell) and the offset between the timing reference of the other cell (that is, the second cell) and the timing reference of the first cell. During the continuous switching process, if the target cell is a second cell, the terminal can adjust the first SMTC based on the offset between the timing reference of the second cell and the timing reference of the first cell to obtain the target SMTC. If the target cell is the first cell, the first SMTC can be directly applied.
[0101] In another embodiment of the present application, the SMTC information may include: the offset between the timing references of each two third cells in the plurality of third cells and the first SMTC corresponding to the first cell. The third cells are all cells that the terminal may access, and the first cell is one of the plurality of third cells.
[0102] Further, after determining the target cell, the terminal may determine the target SMTC based on the offset between the timing references of the third cell and the first SMTC corresponding to the first cell.
[0103] Among them, the information used to configure the first SMTC corresponding to the first cell and the offset between the timing reference of one or more second cells and the timing reference of the first cell, or the information used to configure the SMTC corresponding to the first cell and the offset between the timing references of each two third cells in multiple third cells can be called second configuration information.
[0104] It should be noted that, the embodiment of the present application describes: adjusting SMTC according to the offset between timing references may refer to adjusting SMTC according to the offset between timing references to obtain an adjusted SMTC. Alternatively, adjusting SMTC according to the offset between timing references may also refer to adjusting the SSB measurement timing determined by SMTC according to the offset between timing references to obtain an adjusted SSB measurement timing.
[0105] about Figure 3 For more information, see Figure 2 The relevant description will not be repeated here.
[0106] Reference Figure 4 , Figure 4 It is a flow chart of another measurement method in the embodiment of the present application. Figure 4 The method shown can be applied to a terminal. Figure 4 The illustrated method may include step S41.
[0107] Step S41: after accessing the target cell, measuring the SSB on the first frequency based on the absolute SMTC corresponding to the first frequency, wherein the absolute SMTC is based on absolute time.
[0108] The absolute time may refer to Greenwich Mean Time or Coordinated Universal Time.
[0109] Before step S41, the network device may send SMTC information corresponding to the first frequency to the terminal, wherein the SMTC information may be used to configure an absolute SMTC corresponding to the first frequency.
[0110] Specifically, the absolute SMTC corresponding to the first frequency may include an offset parameter and a period parameter, and the offset parameter and the period parameter may be used to determine the timing of SSB measurement on the first frequency. Among them, the offset parameter may be set by the network device according to a certain absolute time. Exemplarily, the offset parameter may be set at the start time of Greenwich Mean Time or Coordinated Universal Time. In other words, the absolute SMTC is based on the start time of Greenwich Mean Time or Coordinated Universal Time, but is not limited thereto.
[0111] In step S41, the terminal can determine the SSB measurement timing on the first frequency according to the absolute SMTC. Since the absolute SMTC is based on the absolute time, the determined SSB measurement timing is also the absolute time. Further, the terminal can determine the time domain position of the SSB measurement timing determined based on the absolute SMTC on the target cell according to the absolute time message of the target cell.
[0112] Exemplarily, the absolute time message can be carried in a system information block (SIB), for example, SIB9. Specifically, the terminal can determine the reception time of SIB9 according to the absolute time message carried in SIB9 broadcast by the target cell, and the reception time is the absolute time. Furthermore, combining the reception time of SIB9 and the absolute SMTC can determine the timing of the terminal to perform SSB measurement on the first frequency when accessing the target cell.
[0113] From the above, in the scheme of the embodiment of the present application, the network device can configure the SMTC based on absolute time. With such a scheme, the offset parameter in the SMTC can be decoupled from the timing reference of the cell. Since the reference time (or time reference) on which the offset parameter is based is always fixed, the SSB measurement timing determined based on the absolute SMTC is also an absolute time. In the continuous switching scenario, no matter which cell the terminal switches to, the terminal can always accurately determine the SSB measurement timing on the first frequency, which is not affected by the timing reference of the target cell accessed. Therefore, it is helpful to determine the timing of the terminal to perform SSB measurement on the first frequency when accessing the target cell, and avoid the problem of missing measurements when performing cell measurements on the first frequency in the target cell.
[0114] about Figure 4 For more details, please refer to the above description and will not be repeated here.
[0115] Reference Figure 5 , Figure 5 This is a signaling interaction diagram of the second configuration method in an embodiment of the present application. Figure 5 The illustrated method may include step S51 . Figure 5 The method shown can be applied to continuous CPC.
[0116] Step S51: The network device sends configuration information to the terminal. The configuration information may include an update execution condition corresponding to the first candidate PSCell. The measurement object corresponding to the update execution condition includes a second SMTC. The second SMTC is based on a timing reference of the primary cell PCell.
[0117] The first candidate PSCell may be any candidate PSCell configured by the secondary base station in the continuous CPC scenario. It should be noted that the secondary base station in the embodiment of the present application may refer to a candidate secondary base station in the CPC scenario.
[0118] It can be understood by those skilled in the art that the update execution condition can be configured by a measurement identifier (MeasurementIdentity, MeasId), and a measurement identifier is associated with a measurement object identifier (MeasObjectID) and a reporting configuration identifier (ReportConfigId). Specifically, the configuration information may include the measurement identifier of the update execution condition, and the measurement object identifier and reporting configuration identifier associated with the measurement identifier.
[0119] Therefore, the measurement object corresponding to the update execution condition in the embodiment of the present application may refer to the measurement object identified by the measurement object identifier associated with the measurement identifier of the update execution condition.
[0120] In the solution of the embodiment of the present application, the measurement object corresponding to the update execution condition may include a second SMTC, and the second SMTC is based on the timing reference of the PCell.
[0121] In a specific implementation, the timing reference of the second SMTC based on PCell can be indicated by an explicit information element. Exemplarily, the measurement object corresponding to the update execution condition may include an indication information element, which can be used to indicate that the second SMTC in the measurement object is based on the timing reference of PCell. Alternatively, the timing reference of the second SMTC based on PCell can be implicitly determined. Exemplarily, for the continuous CPC scenario, the protocol defaults that the SMTC configured in the update execution condition of the candidate PSCell is based on PCell as the timing reference.
[0122] With such a solution, in a continuous CPC scenario, when the network device (herein, the candidate secondary base station) configures the SMTC for the measurement object to which the candidate PSCell belongs based on the timing reference of the PCell when configuring the update execution conditions of the candidate PSCell. The terminal can determine the SSB measurement timing on the candidate PSCell based on the second SMTC in the measurement object corresponding to the update execution conditions of the candidate PSCell. Since the second SMTC is based on the timing reference of the PCell, no matter which PSCell the terminal accesses, as long as the PCell to which the terminal accesses remains unchanged, the terminal can accurately determine the SSB measurement timing on the candidate PSCell based on the timing reference of the PCell and the second SMTC.
[0123] In the specific implementation, Figure 5 The network device in the network can be a primary base station or a secondary base station. Figure 5 For more information, please refer to Figure 6 and Figure 7 For the related description, please refer to the above related description, which will not be repeated here.
[0124] Reference Figure 6 , Figure 6 This is a signaling interaction diagram of the third configuration method in an embodiment of the present application. Figure 6 The illustrated solution may include steps S61 to S63. Optionally, Figure 6 The illustrated solution may further include step S60. Figure 6 The method shown can be used for continuous CPC scenarios.
[0125] Step S61: The primary base station sends second SMTC or time offset information to the secondary base station.
[0126] Before step S61, step S60 may be performed first. In step S60, the secondary base station sends second indication information and / or the identifier of the first candidate PSCell to the primary base station. The second indication information may be used to indicate the frequency where the first candidate PSCell is located.
[0127] After receiving the second indication information and / or the identifier of the first candidate PSCell, the primary base station may return the second SMTC or time offset information to the secondary base station.
[0128] The second SMTC can be applied to the frequency where the first candidate PSCell is located, and the second SMTC is based on the timing reference of the PCell. The time offset information can be used to indicate the offset between the timing reference of the PCell and the timing reference of the current PSCell, and the time offset information can be used to determine the second SMTC. The current PSCell may refer to the PSCell to which the terminal is connected when step S61 is executed. The current PSCell and the first candidate PSCell may belong to the same secondary base station, or may belong to different secondary base stations.
[0129] In a possible implementation, in step S61, the primary base station sends the second SMTC to the secondary base station. Further, the secondary base station can configure an update execution condition for the first candidate PSCell, and configure a measurement identifier corresponding to the update execution condition, a measurement object identifier associated with the measurement identifier, and a reporting configuration identifier to generate configuration information. The measurement object identified by the measurement object identifier includes the second SMTC.
[0130] In another possible implementation, in step S61, the primary base station sends time offset information to the secondary base station, so that the secondary base station can learn the timing reference of the PCell. After step S61, the secondary base station can first configure the second SMTC according to the timing reference of the PCell. Further, the secondary base station can configure the update execution condition for the first candidate PSCell, and configure the measurement identifier corresponding to the update execution condition, the measurement object identifier associated with the measurement identifier, and the reporting configuration identifier to generate configuration information.
[0131] In other embodiments of the present application, the primary base station may also actively send the second indication information and / or the time offset information to the secondary base station, which is not limited in this embodiment.
[0132] Step S62: The secondary base station sends configuration information to the primary base station.
[0133] Specifically, after the secondary base station generates the configuration information, the secondary base station may send the complete configuration information (ie, the update execution condition of the candidate PSCell) to the primary base station. Optionally, the configuration information may also include an identifier of the first candidate PSCell.
[0134] Step S63: The primary base station sends configuration information to the terminal.
[0135] In other embodiments of the present application, after step S61, the secondary base station may also directly send configuration information to the terminal. Specifically, if the first candidate PSCell is a candidate PSCell of the intra-SN configured by the secondary base station for the terminal, the secondary base station may directly send configuration information to the terminal.
[0136] Reference Figure 7 , Figure 7 This is a schematic diagram of signaling interaction of the fourth configuration method in the embodiment of the present application. Figure 7 The illustrated solution may include steps S71 to S72. Figure 7 The illustrated solution may further include step S70.
[0137] Step S70: The secondary base station sends second indication information and / or an identifier of the first candidate PSCell to the primary base station.
[0138] The second indication information may be used to indicate the frequency at which the first candidate PSCell is located.
[0139] Step S71: The secondary base station sends a reporting condition configuration corresponding to the first candidate PSCell to the primary base station.
[0140] Among them, the reporting condition configuration can be used to configure the event corresponding to the update execution condition, and the event can also be called a reporting condition. Specifically, the event may include at least one of the following: A3 event, A5 event, etc. Among them, the A3 event is that the signal quality of the candidate PSCell is higher than the serving PSCell by a preset offset; the A5 event is that the signal quality of the serving PSCell is lower than threshold 1, and the signal quality of the candidate PSCell is higher than threshold 2. The reporting condition configuration can be used to configure the event that triggers CPC, and the event can be an event defined in an existing protocol or an event defined in a future protocol, and this embodiment does not limit this.
[0141] Optional, Figure 7 The illustrated solution may further include step S70. Exemplarily, step S70 may be performed together with step S71. In other embodiments, step S70 may be performed before step S71, or may be performed after step S71.
[0142] After receiving the reporting condition configuration corresponding to the first candidate PSCell, the master base station may generate the update execution condition or the measurement identifier corresponding to the update execution condition according to the reporting condition configuration. In addition, the master base station may also configure the second SMTC in the measurement object corresponding to the update execution condition.
[0143] Furthermore, the master base station may generate configuration information according to the measurement identifier, the measurement object identifier associated with the measurement identifier, and the reporting configuration identifier.
[0144] Step S72: The primary base station sends configuration information to the terminal.
[0145] Different from Figure 6 The scheme shown, Figure 7 In the illustrated solution, the master base station generates complete configuration information of the update execution condition of the first candidate PSCell.
[0146] In other embodiments of the present application, in a continuous CPC scenario, the main base station or the secondary base station may configure an SMTC reference configuration (or referred to as a "reference SMTC configuration") on a certain frequency to the terminal, wherein the SMTC reference configuration may be based on the timing reference of the current PSCell, and the "current PSCell" here may refer to the PSCell to which the terminal is connected when the base station configures the SMTC reference configuration. In this case, the terminal may always record the downlink timing information of the cell, so that the terminal can adjust the SMTC reference configuration according to the offset between the timing reference of the latest target PSCell and the downlink timing information of the cell during the continuous CPC process, obtain the target SMTC, and thereby determine the SSB measurement timing on the target PSCell.
[0147] From the above, the solution provided by the embodiment of the present application can address the problem that the SMTC configured in the existing solution cannot be applied to different service cells due to the lack of synchronization between different cells in the continuous switching scenario. Based on the solution provided by the embodiment of the present application, the SMTC can be reasonably adjusted, so that the SSB measurement timing can be accurately determined when accessing different target cells, thereby ensuring the order of continuous switching.
