[0063] The embodiments of this disclosure will now be further described in conjunction with the accompanying drawings and specific implementation details.

[0064] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with those of this disclosure.

These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of embodiments of this disclosure, first instruction information may also be referred to as second instruction information, and similarly, second instruction information may also be referred to as first instruction information. Depending on the context, the words “if” and “suppose” as used herein may be interpreted as “when”, “when”, or “in response to a determination”.

[0067] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting this disclosure.

[0068] like Figure 1 As shown, the method provided in this embodiment can be applied to a wireless communication system 100, which may include a user equipment 101, a first network device 102, and a second network device 103, and the number of the three devices is not limited. The user equipment 101 is configured to support dual connectivity.

[0069] It should be understood that the wireless communication system 100 described above is applicable to both low-frequency and high-frequency scenarios. Application scenarios for the wireless communication system 100 include, but are not limited to, long-term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, worldwide interoperability for microwave access (WiMAX) communication systems, cloud radio access network (CRAN) systems, future 5th-generation (5G) systems, new radio (NR) communication systems, or future evolved public land mobile network (PLMN) systems.

[0070] The user equipment 101 shown above can be a terminal, access user equipment, user equipment unit, user equipment station, mobile station (MS), remote station, remote user equipment, mobile user equipment (mobile terminal), wireless communication equipment, user equipment agent, etc. This user equipment 101 may have wireless transceiver capabilities, enabling it to communicate (e.g., wirelessly) with one or more network devices in one or more communication systems, and to receive network services provided by the network devices. These network devices include, but are not limited to, the network device 103 shown in the figure.

[0071] User equipment 101 can be a cellular phone, cordless phone, session initiation protocol (SIP) phone, wireless local loop (WLL) station, personal digital assistant (PDA) device, handheld device with wireless communication capabilities, computing device or other processing device connected to a wireless modem, vehicle-mounted device, wearable device, user equipment in a future 5G network or user equipment in a future evolved PLMN network, etc.

[0072] The first network device 102 and the second network device 103 can be of the same type or different types. For example, both the first network device 102 and the second network device 103 can be access network devices (or access sites). Access network devices refer to devices that provide network access functions, such as radio access network (RAN) base stations, etc. Specifically, they may include base stations (BS), or base stations and radio resource management equipment used to control base stations, and may also include relay stations (relay equipment), access points, and base stations in future 5G networks, base stations in future evolved PLMN networks, or NR base stations, etc., and can be wearable devices or vehicle-mounted devices. Network device 102 can also be a communication chip with a communication module.

[0073] For example, the first network device 102 and the second network device 103 include, but are not limited to: next-generation base stations (gnodeB, gNB) in 5G, evolved node B (eNB) in LTE systems, radio network controllers (RNC), node B (NB) in WCDMA systems, radio controllers and base station controllers (BSC) in CRAN systems, base transceiver stations (BTS) in GSM or CDMA systems, home base stations (e.g., home evolved nodeB, or home node B, HNB), baseband units (BBU), transmitting and receiving points (TRP), transmitting points (TP), or mobile switching centers, etc.

[0074] A dual connection can be at least one of the following:

[0075] EN-DC refers to dual connectivity between 4G radio access network and 5G NR;

[0076] NE-DC refers to dual connectivity between 5G NR and 4G radio access network;

[0077] NR-DC stands for New Radio Dual Connectivity, which allows a single UE to connect to both a sub-6GHz node (gNB) and an mmWave node (gNB).

[0078] Dual connectivity provides the ability to utilize two independently operating cell groups (CGs) to provide radio resources. The two cell groups can be independently controlled by two different radio nodes, and both radio nodes are connected to a single core network. Dual connectivity aims to improve user throughput and enhance mobility resilience. Dual connectivity typically includes a master cell group (MCG) and a secondary cell group (SCG). Generally, the cell in which the UE first initiates Random Access Channel (RACH) belongs to the MCG, and the other group is the SCG.

[0079] In one possible implementation, the MCG includes a primary cell (PCell) and at least one secondary cell (SCell). The PCell is managed by the primary node, and each SCell is managed by a corresponding network node.

[0080] The SCG includes Primary Secondary Cells (PSCells) and Secondary Cells (SCells). PSCells are managed by secondary nodes, and each SCell is managed by a corresponding network node.

[0081] The first network device in this disclosure can be the master node in a dual-connection system, and the second network device can be the slave node in a dual-connection system.

[0082] The measurement interval configured for the UE can have different types, for example:

[0083] The first type is competitive; the corresponding measurement interval is called the concurrent measurement gap.

[0084] The second type is the pre-configured type; the corresponding measurement interval is called the pre-configured measurement gap. The status of the pre-configured measurement gap can be set according to the network side instructions, or it can be set by the UE itself.

[0085] Measurement intervals can be applied to different frequency bands. For example, when the frequency ranges of 5G NR are defined as FR1 and FR2 respectively, they can be divided into per-UE gap and per-FR gap. The per-UE gap refers to the gap shared by FR1 and FR2, while the per-FR gap refers to the gap that can only be used within FR1 or FR2. The frequency range FR1 can be the commonly referred to 5G Sub-6GHz (below 6GHz) band, and the frequency range FR2 can be the 5G millimeter wave band.

[0086] Optionally, for UEs that support Per-FR capability, under EN-DC, the primary node (MN) is configured with the measurement interval of FR1, and the secondary node (SN) is configured with the measurement interval of FR2; for NR-DC and NE-DC, the primary node (MN) is configured with the measurement intervals of FR1 and FR2.

[0087] Optionally, for UEs that support Per-UE capability, the master node (MN) configures all measurement intervals shared by FR1 and FR2.

[0088] In scenarios where the UE uses dual connectivity, when the PSCell performs an active Bandwidth Part (BWP) handover, the PCell is unaware of the PSCell's active BWP handover, preventing the PCell from determining an accurate pre-configured measurement interval for the UE. Therefore, it is necessary for the PSCell to notify the PCell of the new active BWP state after an active BWP handover occurs in a cell within the secondary cell group, enabling the PCell to configure the measurement interval for the UE based on the new active BWP state.

[0089] Optionally, the first network device in this disclosure can be the master node in the dual-connection, used to manage the PCell in the MCG in the dual-connection, and the second network device can be the slave node in the dual-connection, used to manage the PSCell in the SCG in the dual-connection.

[0090] This disclosure provides a method for transmitting information, performed by a second network device. Figure 2 This is a flowchart illustrating a method for transmitting information performed by a second network device according to an exemplary embodiment. Figure 2 As shown, the method includes:

[0091] S201: Send a first indication message to the first network device. The first indication message is used to indicate the status information after activating the BWP handover.

[0092] In some possible implementations, the first instruction information can be sent to the first network device via the Xn interface or the NG interface.

[0093] In some possible implementations, in scenarios where the UE uses dual connectivity, the state information indicated by the first indication information after the BWP activation handover is at least one of the following:

[0094] Status information of PSCell in dual-connectivity secondary cell group after BWP activation and handover.

[0095] Status information of BWP handover activation for SCells in dual-connectivity secondary cell groups.

[0096] Optionally, the status information indicated by the first indication information after the active BWP handover is: the status information of the active BWP of the cell in the secondary cell group that underwent the active BWP handover after the handover. This can be understood as indicating to the first network device the status information of the active BWP of the cell that underwent the active BWP handover in the secondary cell group.

[0097] In some possible implementations, the first indication information includes a cell identifier and the BWP identifier of the active BWP corresponding to the cell identifier. The cell identifier and the BWP identifier can accurately indicate which active BWP in which cell has undergone active BWP handover.

[0098] Optionally, the first network device has configured a pre-configured measurement interval for the dual-connected UE. That is, the second network device only sends the first indication information to the first network device when the first network device has configured a pre-configured measurement interval for the UE. If the first network device has not configured a pre-configured measurement interval for the UE, the second network device does not need to send the first indication information to the first network device.

[0099] Optionally, the second network device needs to confirm whether the first network device has configured a pre-configured measurement interval for the UE. Optionally, this confirmation can be made based on the measurement interval type information sent by the first network device to the second network device. The measurement interval type information is used to indicate the type of each measurement interval configured by the first network device for the UE. The measurement interval may include at least one of the following: contention measurement interval, pre-configured measurement interval, and Network Controlled Small Gap (NCSG).

[0100] Optionally, the first network device is determined to have configured a pre-configured measurement interval for the UE if at least one measurement interval configured for the UE as indicated in the measurement interval type information is a pre-configured measurement interval. In one example, all or part of the measurement intervals configured for the UE as indicated in the measurement interval type information are pre-configured measurement intervals.

[0101] Optionally, the first network device is determined not to have configured a pre-configured measurement interval for the UE if all measurement intervals configured for the UE as indicated in the measurement interval type information are not pre-configured measurement intervals. In one example, all measurement intervals configured for the UE as indicated in the measurement interval type information are non-pre-configured measurement intervals, such as contention measurement intervals, NCSG, or other types of measurement intervals.

[0102] In this embodiment of the disclosure, after a BWP handover occurs in the cell managed by the second network device, the second network device promptly notifies the first network device of the status information after the BWP handover, so that the first network device can promptly know that a BWP handover has occurred in the cell managed by the second network device and apply the status after the BWP handover to various required processes.

[0103] This disclosure provides a method for transmitting information, performed by a second network device. Figure 3 This is a flowchart illustrating a method for transmitting information performed by a second network device according to an exemplary embodiment. Figure 3 As shown, the method includes S301 to S302, specifically:

[0104] S301, Receive measurement interval type information sent by the first network device, the measurement interval type information being used to indicate the type of measurement interval configured by the first network device for the UE.

[0105] Optionally, the measurement interval may include at least one of the following: competitive measurement interval, pre-configured measurement interval, and NCSG.

[0106] In some possible implementations, at least one set of measurement intervals configured by the first network device for the UE is a pre-configured measurement interval. In one example, all or some of the measurement intervals configured by the first network device for the UE are pre-configured measurement intervals. In another example, if the first network device configures only one set of measurement intervals for the UE, then that set of measurement intervals configured by the first network device for the UE is a pre-configured measurement interval.

[0107] In one example, when the first network device configures Y sets of measurement intervals for the UE, the measurement interval type information indicates the type of all or part of the measurement intervals in the Y sets of measurement intervals, where Y is an integer greater than or equal to 1.

[0108] S302, send a first indication message to the first network device. The first indication message is used to indicate the status information after activating the BWP handover.

[0109] Optionally, the first indication information is sent to the first network device only if it is determined, based on the known type of measurement interval configured by the first network device for the UE, that the first network device has configured a pre-configured measurement interval for the UE. If it is determined, based on the known type of measurement interval configured by the first network device for the UE, that the first network device has not configured a pre-configured measurement interval for the UE, the first indication information is not sent to the first network device. The content in S302 is the same as that in S201; please refer to the content of S201, and it will not be repeated here.

[0110] Any step in this embodiment can be combined with any optional example or optional implementation method corresponding to any embodiment in all the above embodiments.

[0111] In this embodiment of the disclosure, the second network device learns from the first network device the type of measurement interval configured by the first network device for the UE. After a BWP handover occurs in the cell it manages, the second network device promptly notifies the first network device of the status information after the BWP handover. This allows the first network device, which has configured a pre-configured measurement interval for the UE, to promptly learn that a BWP handover has occurred in the cell managed by the second network device. The first network device can then confirm whether the BWP handover will affect the measurements performed by the UE using the pre-configured measurement interval. If it will have an impact, the second network device promptly reconfigures the status of the pre-configured measurement interval for the UE to ensure that the status of the UE's pre-configured measurement interval is correct and reasonable, thus preventing any impact on the UE's measurements.

[0112] This disclosure provides a method for transmitting information, performed by a second network device. Figure 4 This is a flowchart illustrating a method for transmitting information performed by a second network device according to an exemplary embodiment. Figure 4 As shown, the method includes S401 to S403, specifically:

[0113] S401, send the first configuration information to the first network device.

[0114] Optionally, the first configuration information sent to the first network device is the configuration information of BWP.

[0115] In some possible implementations, the configuration information of the BWP is at least one of the following:

[0116] The configuration information of the BWP in the PSCell of the dual connection,

[0117] The configuration information of the BWP of the SCell in the secondary cell group of the dual connectivity.

[0118] In some possible implementations, the configuration information of the BWP includes the cell identifier and the configuration information of the BWP corresponding to the cell identifier.

[0119] In some possible implementations, the first configuration information can be sent to the first network device via the Xn interface or the NG interface.

[0120] S402, receive measurement interval type information sent by the first network device, the measurement interval type information being used to indicate the type of measurement interval configured by the first network device for the UE.

[0121] The content in S402 is the same as that in S301. Please refer to the content in S301. It will not be repeated here.

[0122] S403, send a first indication message to the first network device. The first indication message is used to indicate the status information after activating the BWP handover.

[0123] The content of S403 is the same as that of S201. Please refer to the content of S201, and it will not be repeated here.

[0124] In this embodiment of the disclosure, the execution order of S401 and S402 can be interchanged.

[0125] Any step in this embodiment can be combined with any optional example or optional implementation method corresponding to any embodiment in all the above embodiments.

[0126] In this embodiment, the second network device sends BWP configuration information to the first network device, enabling the first network device to learn the BWP configuration information and use it in its required processing. The second network device also learns from the first network device the type of measurement interval configured for the UE. After a BWP handover occurs in the cell it manages, the second network device promptly notifies the first network device of the BWP handover status information. This allows the first network device, which has configured a pre-configured measurement interval for the UE, to promptly learn that a BWP handover has occurred in the cell managed by the second network device. It then confirms whether the BWP handover will affect measurements performed by the UE using the pre-configured measurement interval. If it will affect measurements, the second network device promptly reconfigures the pre-configured measurement interval status for the UE, ensuring the pre-configured measurement interval status is correct and reasonable, thus preventing any impact on the UE's measurements.

[0127] This disclosure provides a method for transmitting information, performed by a first network device. Figure 5 This is a flowchart illustrating a method for transmitting information performed by a first network device according to an exemplary embodiment. Figure 5 As shown, the method includes S501, specifically:

[0128] S501, Receive first indication information sent by the second network device, the first indication information being used to indicate the status information after the active bandwidth portion BWP is switched.

[0129] In some possible implementations, the first indication information sent by the second network device can be received through the Xn interface or the NG interface.

[0130] In some possible implementations, in scenarios where the UE uses dual connectivity, the state information indicated by the first indication information after the BWP activation handover is at least one of the following:

[0131] Status information of the activated BWP in the secondary cell group of dual connectivity after handover in dual connectivity.

[0132] Status information of BWP handover activation for SCells in dual-connectivity secondary cell groups.

[0133] Optionally, the status information indicated by the first indication information after the active BWP handover is: the status information of the active BWP of the cell in the secondary cell group that underwent active BWP handover after the handover. This can be understood as follows: which cell in the secondary cell group underwent active BWP handover can be identified from the second network device, indicating which cell's active BWP status information occurred after the handover.

[0134] In some possible implementations, the first indication information includes a cell identifier and the BWP identifier of the active BWP corresponding to the cell identifier. The cell identifier and the BWP identifier can accurately indicate which active BWP in which cell has undergone active BWP handover.

[0135] Optionally, the first network device has configured a pre-configured measurement interval for the dual-connected UE. That is, the first network device can only receive the first indication information sent by the second network device when the first network device has configured a pre-configured measurement interval for the UE. If the first network device has not configured a pre-configured measurement interval for the UE, it will not receive the first indication information sent by the second network device.

[0136] Optionally, the second network device needs to confirm whether the first network device has configured a pre-configured measurement interval for the UE. For example, it can confirm this based on the measurement interval type information sent by the first network device to the second network device. The measurement interval type information is used to indicate the type of each measurement interval configured by the first network device for the UE. The measurement interval may include at least one of the following: a contention measurement interval, a pre-configured measurement interval, or an NCSG.

[0137] Optionally, the second network device determines that the first network device has configured a pre-configured measurement interval for the UE if at least one measurement interval configured for the UE as indicated in the measurement interval type information is a pre-configured measurement interval. In one example, all or part of the measurement intervals configured for the UE as indicated in the measurement interval type information are pre-configured measurement intervals.

[0138] Optionally, the second network device determines that the first network device has not configured a pre-configured measurement interval for the UE if the following condition is met: all measurement intervals configured for the UE as indicated in the measurement interval type information are not pre-configured measurement intervals. In one example, all measurement intervals configured for the UE as indicated in the measurement interval type information are non-pre-configured measurement intervals, such as contention measurement intervals, NCSG, or other types of measurement intervals.

[0139] Optionally, the second network device sends the first indication information only when it determines, based on the type of measurement interval configured by the first network device for the UE, that the first network device has configured a pre-configured measurement interval for the UE. If, based on the type of measurement interval configured by the first network device for the UE, it determines that the first network device has not configured a pre-configured measurement interval for the UE, the second network device does not send the first indication information to the first network device.

[0140] Any step in this embodiment can be combined with any optional example or optional implementation method corresponding to any embodiment in all the above embodiments.

[0141] In this embodiment of the disclosure, the first network device receives a first indication message sent by the second network device, and can learn the status information of the second network device after the activation of BWP handover in the cell it manages, and thus use the status information for various processes required by it.

[0142] This disclosure provides a method for transmitting information, performed by a first network device. Figure 6 This is a flowchart illustrating a method for transmitting information performed by a first network device according to an exemplary embodiment. Figure 6 As shown, the method includes S601 to S602, specifically:

[0143] S601, receive first indication information sent by the second network device, the first indication information being used to indicate the status information after the active bandwidth portion BWP is switched.

[0144] The content of S601 is the same as that of S501. Please refer to the content of S501, and it will not be repeated here.

[0145] S602, send a second indication information to the UE, the second indication information being used to indicate the status of the pre-configured measurement interval.

[0146] Optionally, the UE can set the state of the pre-configured measurement interval in at least one of the following ways:

[0147] The first setup method involves following the instructions from the network side.

[0148] The second setting method is for the UE to configure it independently.

[0149] If the UE supports the first setting method, the UE sets the state of the pre-configured measurement interval according to the instructions from the network side; if the UE supports the second setting method, the UE can set the state of the pre-configured measurement interval on its own without receiving instructions from the network side.

[0150] Optionally, when sending the second indication information to the UE, the second indication information is sent to UEs that support setting the pre-configured measurement interval according to the network side indication, and not to UEs that support setting the pre-configured measurement interval by setting it themselves.

[0151] In some possible implementations, S602 may further include, before sending the second indication information to the UE, determining that the UE supports setting a pre-configured measurement interval in accordance with the network side indication.

[0152] In some possible implementations, the second indication information sent to the UE is at least one of the following:

[0153] First, send a second indication message to the UE via Radio Resource Control (RRC) signaling or Medium Access Control (MAC) signaling;

[0154] Second, send downlink control information (DCI) to the UE, the downlink control information including the second indication information.

[0155] In some possible implementations, the second instruction information may be determined based on the first instruction information.

[0156] In one example, based on the status information after the active bandwidth portion (BWP) switch indicated by the first indication information, it is determined that all measurement objects associated with a certain set of pre-configured measurement intervals of the UE are located within the active BWP. The status of the set of pre-configured measurement intervals indicated by the second indication information is opposite to the status of the current pre-configured measurement intervals of the UE. That is, if the current pre-configured measurement intervals of the UE are active, then the pre-configured measurement intervals indicated by the second indication information are inactive; if the current pre-configured measurement intervals of the UE are inactive, then the pre-configured measurement intervals indicated by the second indication information are active.

[0157] In another example, when it is determined, based on the status information after the active bandwidth portion (BWP) switch indicated by the first indication information, that at least one measurement object associated with a certain set of configuration measurement intervals of the UE is not located within the active BWP, the status of the set of pre-configured measurement intervals indicated by the second indication information is the same as the status of the current pre-configured measurement intervals of the UE. That is, if the current pre-configured measurement interval of the UE is active, then the status of the pre-configured measurement interval indicated by the second indication information is active; if the current pre-configured measurement interval of the UE is deactive, then the status of the pre-configured measurement interval indicated by the second indication information is deactive.

[0158] Optionally, the measurement object is the relevant information of the frequency point to be measured. Optionally, the relevant information of the frequency point to be measured is the configuration information of the reference signal of the frequency point to be measured. The reference signal is at least one of the following: synchronization signal / physical broadcast channel block (SS / PBCH Block, SSB) and channel state information-reference signal (CSI-RS).

[0159] In some possible implementations, between S601 and S602, the following may be included: determining, based on the first indication information, a state that requires reconfiguration of the pre-configured measurement interval for the UE.

[0160] In one example, when the UE has been configured with at least one set of pre-configured measurement intervals, the status of each set of pre-configured measurement intervals is determined according to the first indication information to determine whether it needs to be reconfigured.

[0161] Optionally, the state of the pre-configured measurement interval can be one of two opposite states, namely active and deactive.

[0162] In one example, based on the first indication information, it is determined that all measurement objects associated with a pre-configured measurement interval of the UE are located within an active BWP, and when the state of the pre-configured measurement interval is active, it is determined that the state of the pre-configured measurement interval needs to be reconfigured, that is, the active state of the pre-configured measurement interval is reconfigured to the deactive state.

[0163] In another example, if it is determined that all measurement objects associated with a pre-configured measurement interval of the UE are located within an active BWP, and the state of the pre-configured measurement interval is active, it is determined that the state of the pre-configured measurement interval does not need to be reconfigured, i.e., the active state of the pre-configured measurement interval is maintained.

[0164] In another example, if it is determined, based on the first indication information, that at least one measurement object related to the pre-configured measurement interval of the UE is not located in an active BWP, and the state of the pre-configured type measurement interval is inactive, it is determined that the state of the pre-configured type measurement interval needs to be reconfigured, that is, the inactive state of the pre-configured measurement interval is reconfigured to the active state.

[0165] In another example, if it is determined, based on the first indication information, that at least one measurement object related to the pre-configured measurement interval of the UE is not located within the active BWP, and the state of the pre-configured measurement interval of the UE is active, it is determined that there is no need to reconfigure the state of the pre-configured measurement interval, that is, to continue to maintain the active state of the pre-configured measurement interval.

[0166] Any step in this embodiment can be combined with any optional example or optional implementation method corresponding to any embodiment in all the above embodiments.

[0167] In this embodiment of the disclosure, by receiving the first indication information sent by the second network device, the active BWP handover of the cell managed by the second network device is promptly known, and the state of the pre-configured measurement interval of the UE is reconfigured, so that the state of the pre-configured measurement interval of the UE remains reasonable and prevents it from affecting the measurement of the UE.

[0168] In this embodiment of the disclosure, the first network device receives the first indication information sent by the first network device, and can know the status information of the second network device after the activation of BWP handover in the cell it manages. Based on the status after the activation of BWP handover, it can confirm whether the activation of BWP handover will affect the measurement performed by the UE using the pre-configured measurement interval. If it will have an impact, it can promptly reconfigure the status of the pre-configured measurement interval for the UE to make the status of the UE's pre-configured measurement interval correct and reasonable, and prevent it from affecting the UE's measurement.

[0169] This disclosure provides a method for transmitting information, performed by a first network device. Figure 7 This is a flowchart illustrating a method for transmitting information performed by a first network device according to an exemplary embodiment. Figure 7 As shown, the method includes S701 to S703, specifically:

[0170] S701 sends measurement interval type information to the second network device.

[0171] This measurement interval type information is used to indicate the type of measurement interval configured by the first network device for the UE.

[0172] Optionally, the measurement interval may include at least one of the following: competitive measurement interval, pre-configured measurement interval, and NCSG.

[0173] In some possible implementations, at least one set of measurement intervals configured by the first network device for the UE is a pre-configured measurement interval. For example, all or part of the measurement intervals in the at least one set of measurement intervals configured by the first network device for the UE are pre-configured measurement intervals. In one example, the first network device configures a set of measurement intervals for the UE, and this set of measurement intervals configured by the first network device for the UE is a pre-configured measurement interval.

[0174] In one example, when the first network device configures Y sets of measurement intervals for the UE, the measurement interval type information indicates the type of all or part of the measurement intervals in the Y sets of measurement intervals, where Y is an integer greater than or equal to 1.

[0175] S702, receive first indication information sent by the second network device, the first indication information being used to indicate the status information after the active bandwidth portion BWP is switched.

[0176] The content of S702 is the same as that of S501. Please refer to the content of S501 for further details.

[0177] S703, send a second indication information to the UE, the second indication information being used to indicate the status of the pre-configured measurement interval.

[0178] S703 is the same as S602; please refer to the content of S602, which will not be repeated here.

[0179] Any step in this embodiment can be combined with any optional example or optional implementation method corresponding to any embodiment in all the above embodiments.

[0180] In this embodiment, the first network device notifies the second network device of the type of measurement interval configured by the first network device for the UE. This allows the second network device to select the first network device that has already configured a pre-configured measurement interval for the UE based on the known type of measurement interval configured by the first network device for the UE. After a BWP handover occurs in the cell managed by the second network device, the second network device promptly notifies the selected first network device of the status information following the BWP handover. This ensures that the first network device, which has configured the pre-configured measurement interval for the UE, is promptly aware of the BWP handover occurring in the cell managed by the second network device. The second network device can then confirm whether the BWP handover will affect the measurements performed by the UE using the pre-configured measurement interval. If it will affect the measurements, the first network device promptly reconfigures the status of the pre-configured measurement interval for the UE, ensuring that the status of the UE's pre-configured measurement interval is correct and reasonable, thus preventing any impact on the UE's measurements.

After a BWP handover occurs in the cell managed by the second network device, the second network device promptly notifies the selected first network device of the BWP handover status information. This ensures that the first network device that has pre-configured a measurement interval for the UE is promptly aware of the BWP handover occurring in the cell managed by the second network device, confirms whether the BWP handover will affect the measurements performed by the UE using the pre-configured measurement interval, and if it will affect the measurements, promptly reconfigures the state of the pre-configured measurement interval for the UE to ensure that the state of the UE's pre-configured measurement interval is correct and reasonable, preventing any impact on the UE's measurements.
