Description

Technical Field

[0001] This application belongs to the field of communication technology, specifically relating to a mobility management method, device, terminal, and medium. Background Technology

[0002] Currently, in mobile communication systems, network-side equipment can configure the terminal to switch from the source primary cell to the target primary cell, and configure the measurement window of the target primary and secondary cells to measure the target primary and secondary cells in order to perform the operation of adding primary and secondary cells (and / or changing secondary nodes), thereby ensuring that the communication between the terminal and the network-side equipment is not interrupted due to the movement of the terminal.

[0003] However, since the timing of the source primary cell and the target primary cell may be different, the terminal may not know whether to apply the measurement window configuration based on the timing of the source primary cell or the target primary cell. This may result in the terminal being unable to quickly measure the downlink reference signal of the target primary and secondary cells, or even cause the measurement of the target primary and secondary cells to fail. Consequently, the terminal may be unable to perform the operation of adding primary and secondary cells (and / or changing secondary nodes).

[0004] This results in poor reliability of terminal communication. Summary of the Invention

[0005] This application provides a mobility management method, apparatus, terminal, and medium that can solve the problem of poor reliability in terminal communication.

[0006] In a first aspect, a mobility management method is provided, comprising: a terminal receiving measurement window configuration information; the terminal applying the measurement window configuration information according to the timing of a first cell; wherein the measurement window configuration information is used to indicate that: during the execution of a target operation, the terminal measures the time domain position of the downlink reference signal of a target primary and secondary cell; the first cell includes either a source primary cell or a target primary cell; the target operation includes at least one of the following: adding a primary or secondary cell, or changing a secondary node.

[0007] Secondly, a mobility management device is provided, comprising a receiving module and a processing module. The receiving module is used to receive measurement window configuration information. The processing module is used to apply the measurement window configuration information received by the receiving module according to the timing of a first cell. The measurement window configuration information is used to indicate that, during the execution of a target operation, the mobility management device measures the time-domain position of the downlink reference signal of a target primary and secondary cell; the first cell includes either a source primary cell or a target primary cell; the target operation includes at least one of the following: adding a primary or secondary cell, or changing a secondary node.

[0008] Thirdly, a terminal is provided, the terminal including a processor, a memory, and a program or instructions stored in the memory and executable on the processor, wherein the program or instructions, when executed by the processor, implement the steps of the method described in the first aspect.

[0009] Fourthly, a terminal is provided, including a processor and a communication interface, wherein the communication interface is used to receive measurement window configuration information. The processor is used to apply the measurement window configuration information received by the receiving module according to the timing of a first cell. The measurement window configuration information is used to indicate that, during the execution of a target operation, the terminal measures the time-domain position of the downlink reference signal of the target primary and secondary cells; the first cell includes either the source primary cell or the target primary cell; the target operation includes at least one of the following: adding a primary or secondary cell, or changing the secondary node.

[0010] Fifthly, a readable storage medium is provided, on which a program or instructions are stored, which, when executed by a processor, implement the steps of the method described in the first aspect.

[0011] In a sixth aspect, a chip is provided, the chip including a processor and a communication interface coupled to the processor, the processor being used to run programs or instructions to implement the method as described in the first aspect.

[0012] In a seventh aspect, a computer program / program product is provided, the computer program / program product being stored in a non-transient storage medium, the computer program / program product being executed by at least one processor to perform the steps of the method as described in the first aspect.

[0013] In this embodiment, the terminal can receive measurement window configuration information. This information instructs the terminal to measure the time-domain position of the downlink reference signal of the target primary / secondary cell during the process of adding a primary / secondary cell (and / or changing a secondary node). The terminal then applies the measurement window configuration information based on the timing of the source primary cell or the target primary cell. Since the terminal can directly determine the application of the measurement window configuration information based on the timing of the source primary cell or the target primary cell after receiving it, it can avoid measurement failures of the target primary / secondary cell. This prevents the terminal from being unable to perform the adding primary / secondary cell operation (and / or changing a secondary node operation), thus improving the reliability of terminal communication.

[0020] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0021] 1. Dual Connectivity (DC)

[0022] The terminal can communicate with two network nodes (access network elements), namely DC. One network node is called the master node (MN), and the other is called the secondary node (SN). The MN and SN may belong to the same network type, for example (MN and SN are both fourth-generation (4G) base stations or both are fifth-generation (5G) base stations), or they may belong to different network types, for example (MN is a 4G base station and SN is a 5G base station).

[0023] In a data center (DC), each network node uses carrier aggregation (CA) technology, which configures a series of serving cells, also known as cell groups, controlled by that network node for the terminal. Among them, the MN controls the master cell group (MCG), and the SN controls the secondary cell group (SCG).

[0024] Both MCG and SCG contain a special cell (SpCell) and a series of secondary cells (Scells). In MCG, the SpCell is called the primary cell (PCell), while in SCG, it is called the primary secondary cell (PSCell). For both MCG and SCG, within a cell group, the SpCell uses the primary carrier, while other secondary cells use secondary carriers. Resource scheduling within a cell group is handled by the SpCell.

[0025] DC can include many different methods:

[0026] EN-DC: The terminal is connected to an ng-eNB as the MN and a gNB as the SN;

[0027] NE-DC: The terminal is connected to a gNB that acts as the MN and an ng-eNB that acts as the SN;

[0028] NR-DC: The terminal is connected to a gNB that acts as the MN and a gNB that acts as the SN.

[0029] 2. Add primary and secondary communities

[0030] The MN can send an add request message to the target SN, which requests the target SN to allocate SCG resources for the terminal. In turn, the target SN can send an add request confirmation message to the MN. This message includes the configuration information of the target primary and secondary cells, as well as the corresponding execution conditions. The MN can then send this configuration information to the terminal, enabling the terminal to measure the target primary and secondary cells. If the measurement results meet the execution conditions, the terminal can apply the configuration of the target primary and secondary cells, initiate random access to the target primary and secondary cells, and complete the synchronization of the target primary and secondary cells.

[0031] 3. Change the auxiliary node

[0032] The MN can send an SN change request message to the target SN, which requests the target SN to allocate SCG resources for the terminal. In this way, the target SN can send an SN change request confirmation message to the MN, which includes the configuration information of the target primary and secondary cells. Thus, the MN can initiate an SN release procedure to the source SN and send the configuration information to the UE, so that the terminal can measure the target primary and secondary cells. If the measurement results meet the execution conditions, the terminal can apply the configuration of the target primary and secondary cells, initiate random access to the target primary and secondary cells, and complete the synchronization of the target primary and secondary cells.

[0037] The mobility management method, apparatus, terminal, and medium provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0038] Figure 2 This application provides a flowchart illustrating a mobility management method according to an embodiment of the present application. This method can be applied to applications such as... Figure 1The image shows a terminal in a wireless communication system. For example... Figure 2 As shown, the mobility management method provided in this application embodiment may include the following steps 101 and 102.

[0039] Step 101: The terminal receives the measurement window configuration information.

[0040] Optionally, in this embodiment of the application, the terminal can receive measurement window configuration information from the network-side device.

[0041] Optionally, in this embodiment of the application, when the terminal communicates with at least one network device, the terminal can receive measurement window configuration information from the network-side device.

[0042] The aforementioned network-side device can be one of the at least one network devices.

[0043] It can be understood that when at least one network device is a single network device, the network-side device is that single network device; when at least one network device is multiple network devices, the network-side device is any one of those multiple network devices.

[0044] In this embodiment of the application, the above-mentioned measurement window configuration information is used to indicate the time domain position of the downlink reference signal of the target primary and secondary cells during the terminal's execution of the target operation.

[0045] Optionally, in this embodiment, the measurement window configuration information can be: System Information Block-based Measurement Timing Configuration (SMTC). It can be understood that the downlink reference signal of the target primary and secondary cells can specifically be: SSB.

[0046] Optionally, in the embodiments of this application, the above-mentioned target operation includes at least one of the following: adding primary and secondary cells, and changing the secondary node.

[0047] Optionally, in this embodiment of the application, the above-mentioned measurement window configuration information includes at least one of the following: the period of the measurement window, the offset of the measurement window, and the duration of the measurement window.

[0048] Optionally, in this embodiment of the application, the network type of the target primary and secondary cells includes any one of the following: New Radio (NR), UMTS Universal Mobile Telecommunications System (UTRA), and Evolved UMTS Terrestrial Radio Access System (EUTRA).

[0049] Step 102: The terminal applies the measurement window configuration information according to the timing of the first cell.

[0050] In this embodiment of the application, the first cell mentioned above includes either the source primary cell or the target primary cell.

[0051] Optionally, in this embodiment of the application, the network type of the source primary cell includes any one of the following: NR, UTRA, EUTRA; the network type of the target primary cell includes any one of the following: NR, UTRA, EUTRA.

[0052] Optionally, in the embodiments of this application, the network type of the source primary cell is different from the network type of the target primary cell; or the network type of the source primary cell is the same as the network type of the target primary and secondary cells.

[0053] Further optionally, in the embodiments of this application, the network type of the source primary cell can be NR, the network type of the target primary cell can be EUTRA, and the network type of the target primary and secondary cells can be NR.

[0054] Specifically, in one example, the source primary cell is sourceNRPCell, the target primary cell is targetEUTRAPCell, and the target primary / secondary cell is targetNRPSCell. Thus, adding a primary / secondary cell can be done from NR SA to EN-DC, and changing the secondary node can be done from NR-DC to EN-DC.

[0055] For example, in a non-dual-connection scenario, the terminal can switch the source NR PCell to the target EUTRAPCell and add the target NRPSCell to perform the target operation; or, in a dual-connection scenario, the terminal can switch the source NR PCell in the MCG controlled by the MN to the target EUTRAPCell in the SCG of another RAT and add the target NR PSCell in the SCG to perform the target operation.

[0056] Specifically, in another example, the source primary cell is source EUTRAPCell, the target primary cell is targetNR PCell, and the target primary / secondary cell is target EUTRAPSCell. Thus, adding a primary / secondary cell can be done from LTESA to NE-DC, and changing the secondary node can be done from EN-DC to NE-DC.

[0057] For example, in a non-dual-connectivity scenario, the terminal can switch the source EUTRA PCell to the target NRPCell and add the target EUTRA PSCell to perform the target operation; or, in a dual-connectivity scenario, the terminal can switch the source EUTRA PCell in the MCG controlled by the MN to the target NR PCell of another RAT and add the target EUTRA PSCell in the SCG to perform the target operation.

[0058] Optionally, in the embodiments of this application, the network-side equipment mentioned above includes any one of the following: the network-side equipment to which the source primary cell belongs, the network-side equipment to which the target primary cell belongs, and the network-side equipment to which the target primary and secondary cells belong.

[0059] Optionally, in this embodiment of the application, the terminal can determine the range of system frame number, subframe, time slot, or symbol corresponding to the measurement window configuration information according to the timing of the first cell, so that the terminal can measure the target primary and secondary cells according to the range of system frame number, subframe, time slot, or symbol.

[0060] It is understandable that the terminal can determine the range of system frame number, subframe, time slot, or symbol of the measurement window corresponding to the measurement window configuration information based on the timing of the first cell, so that the terminal can perform measurements on the target primary and secondary cells within the measurement window.

[0061] Optionally, in the embodiments of this application, step 102 can be implemented by step 102a as described below.

[0062] Step 102a: The terminal performs the target operation based on the timing of the first cell and the application measurement window configuration information.

[0063] The mobility management method provided in this application allows a terminal to receive measurement window configuration information. This information instructs the terminal to measure the time-domain position of the downlink reference signal of the target primary / secondary cell during the process of adding a primary / secondary cell (and / or changing a secondary node). The measurement window configuration information is then applied based on the timing of the source primary cell or the target primary cell. Since the terminal can directly determine the appropriate measurement window configuration information based on the timing of the source primary cell or the target primary cell after receiving it, it can avoid measurement failures of the target primary / secondary cell. This prevents the terminal from being unable to perform the adding primary / secondary cell operation (and / or changing a secondary node operation), thereby improving the reliability of terminal communication.

[0064] Optionally, in the embodiments of this application, the above step 101 can be specifically implemented through the following step 101a.

[0065] Step 101a: The terminal receives measurement window configuration information from the source primary cell via target signaling.

[0066] In this embodiment of the application, the target signaling includes at least one of the following: a first inter-RAT command and a container in the first inter-RAT command; the container includes: the identifier of the target primary cell and first radio parameter information; the first radio parameter information is: radio parameter information related to the radio access technology corresponding to the target primary cell.

[0067] In this embodiment of the application, the measurement window configuration information of the target primary and secondary cells is generated by the source primary cell (based on the timing of the source primary cell or the target primary cell) and sent to the terminal.

[0068] Further optionally, in the embodiments of this application, it can be agreed through an agreement that when performing a target operation, the network-side device can provide measurement window configuration information through the source primary cell; or, the network-side device can provide indication information (such as the target indication information in the embodiments below).

[0069] Further optionally, in the embodiments of this application, the signaling structure of the first inter-RAT command can specifically be: MobilityFromNRCommand-IEs->SSB-MTC.

[0070] Alternatively, in this embodiment of the application, the identifier of the target primary cell can specifically be: the ID of the target primary cell.

[0071] It should be noted that the "wireless access technology corresponding to the target primary cell" mentioned above can be understood as: the wireless access technology of the network type of the target primary cell.

[0072] In this embodiment, the measurement window configuration information of the target primary and secondary cells is generated by the target primary and secondary cells (based on the timing of the source primary cell or the target primary cell) and transparently transmitted to the source primary cell through a container; or it is transparently transmitted to the target primary cell through a container, which in turn transmits it to the source primary cell through a container, and finally sent to the terminal by the source primary cell; or the measurement window configuration information of the target primary and secondary cells is generated by the target primary cell (based on the timing of the target primary cell or the source primary cell), transparently transmitted to the source primary cell through a container, and finally sent to the terminal by the source primary cell.

[0073] Further optionally, in the embodiments of this application, it can be agreed through an agreement that when performing a target operation, the network-side device can provide measurement window configuration information through the source primary cell; or, the network-side device can provide indication information (such as the target indication information in the embodiments below).

[0074] Further optionally, in this embodiment of the application, the first inter-RAT command includes: a complete RRC message.

[0075] Further optionally, in this embodiment, the signaling structure of the first inter-RAT command can specifically be:

[0076] MobilityFromNRCommand-IEs->targetRAT-MessageContaine->RRCConnectionReconfiguration-v1530-IEs->SSB-MTC.

[0077] The following examples will illustrate how the terminal determines the first cell.

[0078] Example 1:

[0079] Optionally, in one possible implementation of this application embodiment, when the terminal receives measurement window configuration information from the source primary cell via a first inter-RAT command, the first cell is the source primary cell.

[0080] It is understandable that, through protocol agreement, if the terminal receives measurement window configuration information from the source primary cell via the first inter-RAT command during the execution of the target operation, the terminal will always apply the measurement window configuration information according to the timing of the source primary cell, that is, the network-side device will always send the application measurement window configuration information according to the timing of the target primary cell.

[0081] Optionally, in another possible implementation of this application embodiment, when the terminal receives measurement window configuration information from the source primary cell via the first inter-RAT command, the first cell is the target primary cell.

[0082] It is understandable that, through protocol agreement, if the terminal receives the measurement window configuration information from the source primary cell via the first inter-RAT command during the execution of the target operation, the terminal will always apply the measurement window configuration information according to the timing of the target primary cell. That is, the network-side device will always send the application measurement window configuration information according to the timing of the target primary cell.

[0083] Optionally, in another possible implementation of this application embodiment, when the terminal receives measurement window configuration information from the source primary cell through the Container, the first cell is the target primary cell.

[0084] It is understandable that, through protocol agreement, if the terminal receives the measurement window configuration information from the source primary cell through the Container in the first inter-RAT command during the execution of the target operation, the terminal will always apply the measurement window configuration information according to the timing of the target primary cell. That is, the network-side device will always send the application measurement window configuration information according to the timing of the target primary cell.

[0085] Optionally, in another possible implementation of this application embodiment, when the terminal receives measurement window configuration information from the source primary cell through the Container, the first cell is the source primary cell.

[0086] It is understandable that, through protocol agreement, if the terminal receives the measurement window configuration information from the source primary cell through the Container in the first inter-RAT command during the execution of the target operation, the terminal will always apply the measurement window configuration information according to the timing of the source primary cell, that is, the network-side device will always send the application measurement window configuration information according to the timing of the source primary cell.

[0087] Thus, it can be seen that since the terminal can directly determine the first cell based on the target signaling, and apply the measurement window configuration information according to the timing of the first cell, without the terminal needing to determine which cell's timing to apply the measurement window configuration information, this facilitates parallel processing by the terminal, thereby shortening the terminal's processing latency and thus reducing the latency of the terminal's measurement.

[0088] Example 2:

[0089] Optionally, in the embodiments of this application, combined with Figure 2 ,like Figure 3 As shown, prior to step 101 above, the mobility management method provided in this application embodiment may further include steps 201 and 202 as described below.

[0090] Step 201: The terminal receives the target indication information.

[0091] Alternatively, in this embodiment of the application, the terminal can receive a first signaling from the aforementioned network-side device, the first signaling including target indication information.

[0092] Specifically, the first signaling can be any of the following: broadcast message, Radio Resource Control (RRC) dedicated signaling, Non-Access Stratum (NAS) signaling, Medium Access Control (MAC) Control Element (CE) signaling, physical layer signaling, etc.

[0093] The broadcast message can be any of the following: System Information Block (SIB) 1, SIB 2, SIB 3, or SIB 4.

[0094] RRC-specific signaling can be any of the following: RRC reconfiguration message, RRC connection establishment message, RRC release message, RRC connection reconstruction message, RRC connection recovery message, or MobilityFromNRCommand.

[0095] In this embodiment of the application, the target indication information is used to instruct the terminal on how to apply the measurement window configuration information.

[0096] Optionally, in the embodiments of this application, step 201 above can be specifically implemented by step 201a below.

[0097] Step 201a: The terminal receives target indication information from the source primary cell through target signaling.

[0098] It is understandable that the terminal can receive target indication information from the network side equipment of the source cell through target signaling.

[0099] In this embodiment of the application, the target signaling includes at least one of the following: a first inter-RAT command and a Container in the first inter-RAT command; the container includes: the identifier of the target primary cell and first radio parameter information; the first radio parameter information is: radio parameter information related to the radio access technology corresponding to the target primary cell.

[0100] Step 202: The terminal determines the first cell based on the target indication information.

[0101] Optionally, in one possible implementation of the embodiments of this application, the target indication information includes at least one of the following: a first indication, a second indication, a third indication, and a fourth indication.

[0102] If the target indication information includes a first indication and / or a second indication, the first cell is the source primary cell.

[0103] The first instruction is used to instruct the terminal to apply measurement window configuration information according to the timing of the source primary cell; the second instruction is used to indicate that the network-side device sends measurement window configuration information to the terminal according to the timing of the source primary cell.

[0104] It is understood that when the target indication information includes the first indication and / or the second indication, the terminal can apply the above measurement window configuration information based on the timing of the source primary cell.

[0105] Further optionally, in this embodiment of the application, the network-side device can represent the first indication with 1 bit. If the bit is 1, it means that the target indication information includes the first indication, that is, the network-side device instructs the terminal to apply the measurement window configuration information based on the timing of the source primary cell. If the bit is 0, it means that the target indication information does not include the first indication (for example, it includes the third indication), that is, the network-side device instructs the terminal to apply the measurement window configuration information based on the timing of the target primary cell.

[0106] The network-side device can also use one bit to represent the first indication. If the bit is true, it means that the target indication information includes the first indication, that is, the network-side device instructs the terminal to apply the measurement window configuration information based on the timing of the source primary cell. If the bit is false, it means that the target indication information does not include the first indication (for example, it includes the third indication), that is, the network-side device instructs the terminal to apply the measurement window configuration information based on the timing of the target primary cell.

[0107] The network-side device can also represent the first indication with one bit. If the bit exists, it means that the target indication information includes the first indication, that is, the network-side device instructs the terminal to apply the measurement window configuration information based on the timing of the source primary cell. If the bit does not exist, it means that the target indication information does not include the first indication (for example, it includes the third indication), that is, the network-side device instructs the terminal to apply the measurement window configuration information based on the timing of the target primary cell.

[0108] The network-side device can also represent the first indication with one bit. If the bit exists and is true, it means that the target indication information includes the first indication, that is, the network-side device instructs the terminal to apply the measurement window configuration information based on the timing of the source primary cell. If the bit does not exist, it means that the target indication information does not include the first indication (for example, it includes the third indication), that is, the network-side device instructs the terminal to apply the measurement window configuration information based on the timing of the target primary cell.

[0109] It should be noted that the description of the second instruction can be referred to the specific description of the first instruction, and will not be repeated here in the embodiments of this application.

[0110] If the target indication information includes a third indication and / or a fourth indication, the first cell is the target primary cell.

[0111] The third instruction is used to instruct the terminal to apply measurement window configuration information according to the timing of the target primary cell; the fourth instruction is used to indicate that the network-side device sends measurement window configuration information to the terminal according to the timing of the target primary cell.

[0112] It is understood that when the target indication information includes a third indication and / or a fourth indication, the terminal can apply the above measurement window configuration information based on the timing of the target primary cell.

[0113] It should be noted that the description of the third instruction can be referred to the specific description of the first instruction, and the description of the fourth instruction can be referred to the specific description of the first instruction. The embodiments of this application will not be repeated here.

[0114] Optionally, in another possible implementation of the embodiments of this application, the target indication information includes any one of the following: a fifth indication, a sixth indication.

[0115] If the target indication information includes the fifth indication and the first condition is met, the first cell is the source primary cell.

[0116] If the target indication information includes the fifth indication and the first condition is not met, the first cell is the target primary cell.

[0117] If the target indication information includes the sixth indication and the second condition is met, the first cell is the target primary cell.

[0118] If the target indication information includes the sixth indication and the second condition is not met, the first cell is the source cell.

[0119] In this embodiment of the application, the first condition includes at least one of the following: the source primary cell and the target primary cell are synchronized, and the primary cell group does not need to be synchronized and reconfigured; the second condition includes at least one of the following: the source primary cell and the target primary cell are not synchronized, and the primary cell group needs to be synchronized and reconfigured; the fifth instruction is used to indicate that: when the first condition is met, the terminal applies measurement window configuration information according to the timing of the source primary cell; the sixth instruction is used to indicate that: when the second condition is met, the terminal applies measurement window configuration information according to the timing of the target primary cell.

[0120] Thus, it can be seen that since the terminal can apply the measurement window configuration information based on the target indication information received, which instructs the terminal to apply the measurement window configuration information, and based on the judgment of the first condition and / or the second condition, it avoids the situation where the terminal cannot measure the downlink reference signal of the target primary and secondary cells due to not knowing whether the measurement window configuration is applied according to the timing of the source primary cell or the target primary cell, thereby ensuring that the reliability of terminal communication is relatively poor.

[0121] Example 3:

[0122] Optionally, in one possible implementation of this application embodiment, the first cell is the source master cell when the first condition is met.

[0123] In this embodiment of the application, the first condition mentioned above includes at least one of the following: the source primary cell and the target primary cell are synchronized, and the primary cell group does not need to be synchronized and reconfigured.

[0124] Alternatively, in the embodiments of this application, the first condition mentioned above may be agreed upon in an agreement.

[0125] It is understandable that the protocol can stipulate that if the source primary cell and the target primary cell are synchronized or the primary cell group does not need to be synchronized and reconfigured, the terminal applies the above measurement window configuration information based on the timing of the source primary cell, so that the terminal can determine whether the first condition is met, and thus determine whether to apply the above measurement window configuration information based on the timing of the source primary cell.

[0126] Thus, it can be seen that when the terminal determines that the first condition is met, it applies the measurement window configuration information based on the source primary cell, avoiding the situation where the terminal does not know whether to apply the measurement window configuration information based on the source primary cell or the target primary cell, enabling the terminal to quickly measure the downlink reference signal of the target primary and secondary cells.

[0127] Optionally, in another possible implementation of this application embodiment, the first cell is the target primary cell when the second condition is met.

[0128] In this embodiment of the application, the second condition mentioned above includes at least one of the following: the source primary cell and the target primary cell are not synchronized, and the primary cell group needs to be synchronized and reconfigured.

[0129] Alternatively, in the embodiments of this application, the second condition mentioned above may be agreed upon in an agreement.

[0130] It is understandable that the protocol can stipulate that if the source primary cell and the target primary cell are out of sync or the primary cell group needs to be synchronized and reconfigured, the terminal can apply the above measurement window configuration information based on the timing of the target primary cell, so that the terminal can determine whether the second condition is met, and thus determine whether to apply the above measurement window configuration information based on the timing of the target primary cell.

[0131] Thus, it can be seen that, since the terminal applies the measurement window configuration information based on the target primary cell when the second condition is met, it avoids the situation where the terminal does not know whether to apply the measurement window configuration information based on the source primary cell or the target primary cell, enabling the terminal to quickly measure the downlink reference signal of the target primary and secondary cells.

[0157] The radio frequency unit 101 is used to receive measurement window configuration information.

[0159] The aforementioned measurement window configuration information is used to indicate that during the execution of the target operation, the terminal measures the time domain position of the downlink reference signal of the target primary and secondary cells; the aforementioned first cell includes either the source primary cell or the target primary cell; the aforementioned target operation includes at least one of the following: adding primary and secondary cells, or changing the secondary node.

[0160] The terminal provided in this application embodiment can directly determine, after receiving the measurement window configuration information, to apply the measurement window configuration information to measure the target primary and secondary cells according to the timing of the source primary cell or the target primary cell. Therefore, it can avoid the situation where the measurement of the target primary and secondary cells fails, thereby avoiding the terminal being unable to perform the operation of adding primary and secondary cells (and / or changing secondary nodes). In this way, the reliability of terminal communication can be improved.

[0161] Optionally, in this embodiment of the application, the radio frequency unit 101 is specifically used to receive measurement window configuration information from the source primary cell through target signaling.

[0165] Thus, it can be seen that since the terminal can apply the measurement window configuration information according to the target indication information received, without the terminal needing to determine which cell's timing to apply the measurement window configuration information, this facilitates parallel processing by the terminal, thereby reducing terminal processing latency and thus reducing the latency of the terminal's measurement.
