Abstract

The present disclosure provides a bandwidth part switching method and apparatus. The bandwidth part switching method is applied to a terminal, and a base station configures at least one bandwidth partBWP for a terminal. The bandwidth part switching method includes: receiving a power saving signal sent by the base station, wherein the power saving signal is a wake-up signal WUS; and performing BWPswitching according to the power saving signal. Therefore, the bandwidth part switching method can perform BWP switching according to the power saving signal, thereby implementing the function of performing BWP switching according to the power saving signal configured by the base station, improving the rate of BWP switching, and reducing the power consumption of the BWP switching.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular, to a method and device for switching bandwidth parts. Background technique [0002] In the new-generation communication system, a carrier bandwidth can be divided into multiple bandwidth parts (Band WidthPart, BWP), and a terminal can be configured with multiple BWPs at the same time, but there can only be at most one active BWP on a serving cell at the same time. Downlink BWP, and an active uplink BWP. Therefore, how to improve the efficiency of the BWP handover becomes particularly important, but there is no optimization scheme for improving the efficiency of the BWP handover in the prior art. Contents of the invention [0003] In order to overcome the problems existing in the related technologies, the embodiments of the present disclosure provide a bandwidth part switching method and device. [0004] According to the first aspect of an embodiment of the...
