As shown in Fig. 1, the method provided in the embodiment of the present disclosure 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. The number of the three devices included is not limited. The user equipment 101 is configured to support dual connectivity.

It should be understood that the above wireless communication system 100 can be applied to both low-frequency scenarios and high-frequency scenarios. The application scenarios of the wireless communication system 100 include, but are not limited to, long-term evolution (LTE) system, LTE frequency division duplex (FDD) system, LTE time division duplex (TDD) system, worldwide interoperability for microwave access (WiMAX) communication system, cloud radio access network (CRAN) system, future fifth-generation (5G) system, new radio (NR) communication system or future evolved public land mobile network (PLMN) system, etc.

The user equipment 101 shown above may be a terminal, an access user equipment, a user equipment unit, a user equipment station, a mobile station (MS), a remote station, a remote user equipment, a mobile user equipment (mobile terminal), a wireless communication device, a user equipment agent, etc. The user equipment 101 may have a wireless transceiver function, and it may communicate with one or more network devices of one or more communication systems (such as wireless communication) and receive network services provided by the network devices, where the network devices include but are not limited to the illustrated network device 103.

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

The first network device 102 and the second network device 103 may be devices of the same type or devices of different types. For example, the first network device 102 and the second network device 103 may both be access network devices (or access network points). Among them, the access network device refers to a device that provides network access functions, such as a radio access network (RAN) base station, etc. Specifically, it may include a base station (BS), or a base station and a wireless resource management device for controlling the base station, etc., and may also include a relay station (relay device), an access point, and a base station in a future 5G network, a base station in a future evolved PLMN network, or an NR base station, etc., which may be a wearable device or a vehicle-mounted device. The network device 102 may also be a communication chip with a communication module.

For example, the first network device 102 and the second network device 103 include, but are not limited to: a next-generation base station (gnodeB, gNB) in 5G, an evolved node B (evolved node B, eNB) in an LTE system, a radio network controller (radio network controller, RNC), a node B (node B, NB) in a WCDMA system, a wireless controller under a CRAN system, a base station controller (basestation controller, BSC), a base transceiver station (base transceiver station, BTS) in a GSM system or a CDMA system, a home base station (for example, home evolved nodeB, or home node B, HNB), a baseband unit (baseband unit, BBU), a transmitting point (transmitting and receiving point, TRP), a transmitting point (transmitting point, TP) or a mobile switching center, etc.

The dual connection may be at least one of the following:

EN-DC refers to the dual connection between 4G wireless access network and 5G NR;

NE-DC refers to the dual connection between 5G NR and 4G wireless access network;

NR-DC, refers to New Radio Dual Connectivity, which allows a single UE to connect to both a sub-6 GHz node (gNB) and a mmWave node (gNB).

Dual connectivity provides the ability to provide wireless resources using two independently operating cell groups (Cell Group, CG). The two cell groups can be independently controlled by two different wireless nodes, and the two wireless nodes are connected to a single core network. Dual connectivity aims to increase user throughput and improve mobility resilience. Under dual connectivity, for example, there is a master cell group (Master Cell group, MCG) and a secondary cell group (Secondary Cell group, SCG). Generally, the group where the UE first initiates random access (Random Access Channel, RACH) is located is the MCG, and the other group is the SCG.

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

SCG includes Primary Secondary Cell (PSCell) and Secondary Cell (SCell). PSCell is managed by the secondary node, and each SCell is managed by the corresponding network node.

The first network device in the present disclosure may be a master node in the dual connection, and the second network device may be a slave node in the dual connection.

The measurement interval configured by the UE can be of different types, for example:

The first type is the competitive type; the corresponding measurement interval is called the concurrent measurement gap;

The second type is a pre-configured type; the corresponding measurement interval is called a pre-configured measurement gap. The state of the pre-configured measurement gap can be set according to the network side instruction or can be set by the UE itself.

The measurement gap can be applicable to different frequency bands. For example, when the frequency ranges of 5G NR are defined as FR1 and FR2, 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, and the per-FR gap refers to the gap that can only be used in FR1 or FR2. The frequency range FR1 can be the commonly referred to 5G Sub-6GHz (below 6GHz) frequency band, and the frequency range FR2 can be the 5G millimeter wave frequency band.

Optionally, for a UE supporting Per-FR capability, under EN-DC, the master node (MN) configures the measurement interval of FR1, and the secondary node (SN) configures the measurement interval of FR2; for NR-DC and NE-DC, the master node (MN) configures the measurement intervals of FR1 and FR2;

Optionally, for a UE supporting the Per-UE capability, the master node (MN) configures all measurement intervals common to FR1 and FR2.

In the scenario where the UE uses dual connectivity, when the PSCell switches the active bandwidth part (Bandwidth Part, BWP), the PCell is unaware of the activeBWP switch of the PSCell, resulting in the PCell being unable to determine an accurate pre-configured measurement interval for the UE. Therefore, it is necessary for the PSCell to notify the PCell of the activeBWP state after the activeBWP switch occurs in the cell in the secondary cell group, so that the PCell configures the measurement interval for the UE according to the new activeBWP state.

Optionally, the first network device in the present disclosure may be a master node in the dual connection, used to manage the PCell in the MCG in the dual connection, and the second network device may be a slave node in the dual connection, used to manage the PSCell in the SCG in the dual connection.

The embodiment of the present disclosure provides a method for transmitting information, which is performed by a second network device. FIG2 is a flowchart of a method for transmitting information performed by a second network device according to an exemplary embodiment. As shown in FIG2, the method includes:

That is, the second network device sends the first indication information to the first network device only when the first network device has configured the preconfigured measurement interval for the UE. If the first network device has not configured the preconfigured measurement interval for the UE, the second network device does not need to send the first indication information to the first network device.

Optionally, the second network device needs to confirm whether the first network device has configured a preconfigured measurement interval for the UE. Optionally, the confirmation can be made according to the measurement interval type information sent by the first network device to the second network device.

In an example, all measurement intervals configured for the UE indicated in the measurement interval type information are non-preconfigured measurement intervals, and the non-preconfigured measurement intervals are, for example, competitive measurement intervals, NCSGs, or other types of measurement intervals.

In the disclosed embodiment, after the BWP activation switch 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 switch is activated, so that the first network device is promptly informed that the BWP activation switch occurs in the cell managed by the second network device, and applies the status after the BWP activation switch to various required processing.

Optionally, the state information after the activation BWP switching indicated by the first indication information is: the state information of the activation BWP of the cell in the secondary cell group in the dual connection where the activation BWP switching occurs after the activation BWP switching occurs. It can be understood that the state information of the activation BWP of the cell after the activation BWP switching occurs can be obtained from the second network device based on which cell in the secondary cell group has the activation BWP switching.

Optionally, the first network device has configured a preconfigured measurement interval for the dual-connected UE.

Optionally, when sending the second indication information to the UE, the second indication information is sent to the UE that supports setting the pre-configured measurement interval according to the network side indication, and the second indication information is not sent to the UE that supports setting the pre-configured measurement interval according to the autonomous setting.

In some possible implementations, before sending the second indication information to the UE in S602, the step may further include: determining whether the UE supports setting the preconfigured measurement interval in accordance with the network side indication.

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

1. Sending second indication information to the UE through Radio Resource Control (RRC) signaling or Medium Access Control (MAC) signaling;

2. Send downlink control information (Downlink Control Information, DCI) to the UE, where the downlink control information includes the second indication information.

In some possible implementations, the second indication information may be determined according to the first indication information.

In one example, it is determined that all measurement objects associated with a set of preconfigured measurement intervals of the UE are located within the activated BWP according to the status information after the activated bandwidth part BWP is switched indicated by the first indication information, and the status of the set of preconfigured measurement intervals indicated by the second indication information is opposite to the status of the current preconfigured measurement interval of the UE, that is: if the status of the current preconfigured measurement interval of the UE is active (active), then the status of the preconfigured measurement interval indicated by the second indication information is deactive (deactive); if the status of the current preconfigured measurement interval of the UE is deactive (deactive), then the status of the preconfigured measurement interval indicated by the second indication information is active (active).

In another example, when it is determined that at least one measurement object associated with a set of configured measurement intervals of the UE is not located within the activated BWP according to the status information after the activated bandwidth part BWP is switched indicated by the first indication information, 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 interval of the UE, that is: if the status of 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 status of 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.

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

In some possible implementations, the step between S601 and S602 further includes: determining, according to the first indication information, a state in which a preconfigured measurement interval needs to be reconfigured for the UE.

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

Optionally, the state of the preconfigured measurement interval may be one of two opposite states, namely, an active state (active) and a deactive state (deactive).

In one example, it is determined based on the first indication information that measurement objects associated with a preconfigured measurement interval of the UE are all located within an activated BWP, and when the state of the measurement interval of the preconfigured type is an activated state (active), it is determined that the state of the preconfigured measurement interval needs to be reconfigured, that is, the activated state (active) of the preconfigured measurement interval is reconfigured to an inactive state (deactive).

In another example, it is determined that measurement objects associated with a preconfigured measurement interval of the UE are all located within an activated BWP, and when the state of the measurement interval of the preconfigured type is an activated state (active), it is determined that there is no need to reconfigure the state of the preconfigured measurement interval, that is, continue to maintain the activated state (active) of the preconfigured measurement interval.

In another example, when it is determined according to the first indication information that at least one measurement object related to the preconfigured measurement interval of the UE is not located in an activated BWP, and the state of the measurement interval of the preconfigured type is in an inactive state (deactive), it is determined that the state of the measurement interval of the preconfigured type needs to be reconfigured, that is, the inactive state (deactive) of the preconfigured measurement interval is reconfigured to an active state (active);

In another example, it is determined according to the first indication information that at least one measurement object related to the preconfigured measurement interval of the UE is not located in the activated BWP, and when the state of the preconfigured measurement interval of the UE is active, it is determined that there is no need to reconfigure the state of the preconfigured measurement interval, that is, continue to maintain the active state of the preconfigured measurement interval.

In the disclosed embodiment, by receiving the first indication information sent by the second network device, it is timely known that the cell managed by the second network device has activated BWP switching, and the state of the pre-configured measurement interval is reconfigured for the UE, so that the state of the pre-configured measurement interval of the UE remains reasonable to prevent affecting the measurement of the UE.

In the disclosed embodiment, the first network device receives the first indication information sent by the first network device, and can obtain the status information of the second network device after the activation of BWP switching occurs in the cell managed by it, and confirm whether the activation of BWP switching will affect the measurement performed by UE using the preconfigured measurement interval according to the status after the activation of BWP switching. If it will cause an impact, the status of the preconfigured measurement interval is reconfigured for the UE in time to make the status of the preconfigured measurement interval of the UE correct and reasonable, so as to prevent affecting the measurement of the UE.
