Claim 9:
10. A device for switching a bandwidth part, applied to a terminal, wherein a base station configures at least one bandwidth part (BWP) for the terminal, and the device comprises:
a processor;
a memory configured to store instructions executable by the processor;
wherein the processor is configured to:
receive a power saving signal transmitted by the base station, the power saving signal being a wake up signaling (WUS), and the WUS being configured to instruct to perform a BWP switching; and
perform the BWP switching based on the power saving signal;
wherein the processor is configured to perform BWP switching based on the power saving signal by:
in response to the WUS not comprising first information for representing a first designated BWP, determining a first target BWP for switching based on a first setting rule, wherein the first setting rule is transmitted by the base station to the terminal through system messages or dedicated signaling; switching a currently activated BWP to the first target BWP; and performing at least one of physical downlink control channel (PDCCH) monitoring or physical downlink shared channel (PDSCH) monitoring on the first target BWP; and
in response to the WUS comprising the first information for representing the first designated BWP, the first designated BWP being a target BWP for switching and configured by the base station for the terminal; determining the first designated BWP for switching based on the first information; switching the currently activated BWP to the first designated BWP; and performing at least one of PDCCH monitoring or PDSCH monitoring on the first designated BWP.
