The embodiments described below by referring to the drawings are exemplary and intended for the purpose of explaining the present disclosure and are not to be construed as limiting the present disclosure.

Among the bandwidth configuration methods, apparatuses, user equipment, base stations and storage media provided in the embodiments of the present disclosure, a base station may receive a first capability change request sent by a UE of the user equipment, where the request includes a new bandwidth capability, and the bandwidth capability is smaller than an original bandwidth capability corresponding to the use of BWP by the UE at a current moment. 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 rejection information, that is, the base station will 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 switching information, that is, the base station may configure BWP corresponding to the new bandwidth capability for the UE, 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 effect of saving electricity can be achieved, and the resource waste caused by always using the original bandwidth capability (large bandwidth) is avoided.

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

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

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

It should be noted that the service control method in the embodiment of the present disclosure may be applied to any UE. A UE may be 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 ), which may be an internet of things terminal such as a sensor device, a mobile phone (or "cellular" phone) and a computer with an internet of things terminal, for example, a fixed, portable, pocket, hand-held, computer-built-in or vehicle-mounted device. Such as a Station (STA), subscriber unit (subscriber unit), subscriber Station (subscriber Station), mobile Station (mobile), remote Station (remote Station), access point, remote terminal (remote), access terminal (access terminal), user device (user terminal), or user agent (user agent). Alternatively, the UE may be a device of an unmanned aerial vehicle. Alternatively, the UE may be a vehicle-mounted device, for example, a laptop with a wireless communication function, or a wireless terminal externally connected to the laptop. Alternatively, the UE may be a roadside device, for example, a street lamp, a signal lamp, or other roadside devices with a wireless communication function.

In one 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 a 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 one embodiment of the present disclosure, the first capability change request may be specifically for: the UE requests to change its bandwidth capability to a smaller new 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 fall back to a small new BWP from the BWP used at the current moment, and achieving the effect of saving power. 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 when in a state where power saving is required. The state requiring power saving may be, for example: and when the electric quantity of the UE is smaller than the threshold value.

Step 102, sending first information to the UE.

Wherein, in one embodiment of the present disclosure, the first information may include: first switching information.

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

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