The embodiments described below with reference to the drawings are exemplary and intended to be illustrative of the present disclosure, and should not be construed as limiting the present disclosure.

Among the bandwidth configuration method, apparatus, user equipment, base station and storage medium provided in the embodiments of the present disclosure, the base station receives a first capability change request sent by the UE of the user equipment, where the request includes a new bandwidth capability, and the new bandwidth capability is smaller than an original bandwidth capability corresponding to the UE using BWP at the current time. Thereafter, the base station transmits first information to the UE, the first information including a new BWP configured for the UE. When the UE receives the first reject information, that is, the base station does not configure a new BWP for the UE, the UE continues to use the BWP used at the current time. And when the UE receives the first handover information, that is, the base station may configure a new BWP corresponding to the new bandwidth capability for the UE, and the UE switches from the BWP used at the current time to the newly configured BWP. In the embodiment of the disclosure, the new bandwidth capability is smaller than the original bandwidth capability, and when the UE uses the new bandwidth capability (small bandwidth), the UE can save power, thereby avoiding resource waste caused by using the original bandwidth capability (large bandwidth) all the time.

A signal receiving method, an apparatus, a user equipment, a base station, and a storage medium provided by the present disclosure are described in detail below with reference to the accompanying drawings.

Fig. 1 is a flowchart illustrating a bandwidth configuration method according to an embodiment of the present disclosure, where the method is executed by a base station, and as shown in fig. 1, the bandwidth configuration method may include the following steps:

step 101, receiving a first capability change request sent by a UE (User Equipment).

It should be noted that the service control method according to the embodiment of the present disclosure may be applied to any UE. A UE may refer to a device that provides voice and/or data connectivity to a user. The UE may communicate with one or more core networks via a RAN (Radio Access Network), and may be an internet of things terminal such as a sensor device, a mobile phone (or referred to as a "cellular" phone), and a computer having the internet of things terminal, for example, a fixed, portable, pocket, handheld, computer-included, or vehicle-mounted device. For example, a Station (STA), a subscriber unit (subscriber unit), a subscriber Station (subscriber Station), a mobile Station (mobile), a remote Station (remote Station), an access point, a remote terminal (remote), an access terminal (access terminal), a user equipment (user terminal), or a user agent (user agent). Alternatively, the UE may be a device of an unmanned aerial vehicle. Or, the UE may also be a vehicle-mounted device, for example, a vehicle computer with a wireless communication function, or a wireless terminal externally connected to the vehicle computer. Alternatively, the UE may be a roadside device, for example, a street lamp, a signal lamp or other roadside device with a wireless communication function.

In an embodiment of the present disclosure, the first capability change request may include a new Bandwidth capability, where the new Bandwidth capability is smaller than a Bandwidth capability (hereinafter referred to as an original Bandwidth capability) corresponding to a BWP (Bandwidth Part) configured by the base station to the UE at the current time.

And, in one embodiment of the present disclosure, the gap between the new bandwidth capability and the original bandwidth capability should be significant. Illustratively, in one embodiment of the present disclosure, the new bandwidth capability may be between [0, original bandwidth capability x 60% ]. For example, the original bandwidth capability is 100M and the new bandwidth capability is 20M.

Further, in an embodiment of the disclosure, the first capability change request may be specifically for: the UE requests to change its bandwidth capability to a new smaller bandwidth capability, so that the UE can subsequently switch the BWP to a new BWP corresponding to the new bandwidth capability based on the new bandwidth capability, thereby enabling the UE to back-off from the currently used BWP to a new small BWP, and achieving the power saving effect. Based on this, in one embodiment of the present disclosure, it may be that the UE transmits the first capability change request to the base station while in a state requiring power saving. The power saving state may be, for example: and when the power of the UE is less than the threshold value.

Step 102, sending the first information to the UE.

Among others, in one embodiment of the present disclosure, the first information may include: first handover information.

And, in one embodiment of the present disclosure, the first information may include: first rejection information.

A specific method for determining the target BWP based on the first information by the base station will be described in the following embodiments.

It can be seen that, in the embodiment of the present disclosure, the base station may configure a new BWP for the UE based on the new bandwidth capability that is smaller than the original bandwidth capability and is sent by the UE, that is, the base station may configure a small BWP for the UE. Therefore, when the UE needs to save power, the base station can reconfigure the small BWP for the UE to reduce the power consumption speed of the UE, so that the power saving effect is good, and the performance of the UE is ensured.
