Description

Method and device for determining configuration information of bandwidth portion BWP

Technical field

The present application relates to the field of communications technologies, and in particular, to a method and an apparatus for determining configuration information of a bandwidth part (BWP).

Background technique

With the continuous development of communication technology, the fifth generation mobile communication system (5G) introduced a bandwidth part (BWP) technology. On one carrier, the base station can configure multiple BWPs for the terminal device to enable support for multiple services. When the base station adds a secondary cell to the terminal device, or the terminal device performs the base station handover, the terminal device receives the synchronous reconfiguration command sent by the base station, and the synchronous reconfiguration command includes the newly configured BWP. Related configuration information, each BWP related configuration information includes a set of BWP common information and a set of BWP specific information. In addition, the base station also adds or modifies the common information or dedicated information of the currently configured BWP through the normal reconfiguration command.

For example, when the terminal device performs the base station handover, the source base station switches the terminal device to the target base station, and the source base station sends a handover request for carrying the configuration information of the current BWP of the terminal device to the target base station; the target base station is to the source The base station returns a handover command that carries configuration information of the BWP required for the terminal device to access the target base station; the terminal device acquires configuration information of the required BWP from the source base station to access the target base station.

As is well known, in LTE, existing information has a default (delta) configuration in the reconfiguration process, so that some information may not be changed, and the configured information may include only changed information to reduce Signaling overhead. However, after the BWP is introduced in the 5G, the base station configures multiple BWPs for the terminal device, and there are multiple BWP configuration information. Therefore, when the BWP configuration information is reconfigured, the existing delta configuration method may cause uncertainty. The configuration information of the specific BWP required, so the delta configuration of the BWP configuration information has not been implemented yet.

1 shows an architecture of a possible communication system to which a method for determining configuration information of a BWP provided by an embodiment of the present application is applicable. The architecture of the communication system includes a base station and a terminal device, where:

The base station is configured to provide a wireless access service for the terminal device. Specifically, the base station may configure multiple BWPs for the terminal device, so that the terminal device supports multiple services. The base station includes, but is not limited to, an evolved Node B (eNB), a radio network controller (RNC), a Node B (NB), and a base station controller. , BSC), base transceiver station (BTS), home base station (for example, home evolved NodeB, or home Node B, HNB), baseband unit (BBU), access point (AP) ), wireless fidelity access point (WiFi AP), worldwide interoperability for microwave access (WiMAX) BS, and the like.

The terminal device is configured to access the base station to perform services. Specifically, the terminal device accesses the base station by using the multiple BWPs configured by the base station, and performs corresponding services.

When the base station needs to add a secondary cell or a BWP configuration of the serving cell to the terminal device, the terminal device needs to configure a BWP in the secondary cell or the serving cell; and the base station is the terminal device. A secondary cell is added, and the base station sends a synchronization reconfiguration message to the terminal device to configure the BWP. When the base station adds or modifies a BWP configuration of an existing serving cell to the terminal device, the base station sends a reconfiguration message to the terminal device. Specifically, in the prior art, the synchronous reconfiguration message or the reconfiguration message usually includes all configuration information of the BWP to be configured, and the terminal device can access the base station according to the configuration information; In an embodiment, the synchronization reconfiguration message or the reconfiguration message may include only partial configuration information of the BWP to be configured, and may be configured by default. The terminal device may be configured according to the part of the BWP to be configured. The configuration information and the BWP configuration information of the originally configured terminal device determine the default configuration information, thereby determining the configuration information of the BWP to be configured.

For example, when the terminal device needs to be handed over from the first base station to the second base station, the first base station sends a handover request to the second base station, where the handover request carries the BWP currently configured by the current terminal device. The configuration information is that the second base station sends a handover response to the first base station, where the handover response includes a handover command, and the first base station sends a handover command to the terminal device by using a synchronous reconfiguration message to configure The BWP under the second base station. For example, when the first base station needs to add the second base station to the secondary base station, the first base station sends a request for adding a secondary base station to the second base station, where the added secondary base station requests Carrying the configuration information of the BWP currently configured by the current terminal device, the second base station sending a response message to the first base station to add the secondary base station, where the response message includes the BWP of the terminal device under the second base station The configuration information is that the first base station sends the configuration information to the terminal device by using a synchronous reconfiguration message to configure a BWP under the second base station.

If the determined BWP configuration information includes the RACH configuration information, the terminal device uses the RACH configuration information. The access configuration is configured to access the second base station.

It should be noted that the communication system shown in FIG. 2 is merely an example, and is not limited to including the device shown in FIG. 2. The communication system may also include other devices, which are not enumerated here.
