Claim 11:
12. A device for switching a bandwidth part, applied to a base station, wherein the base station configures at least one bandwidth part (BWP) for a terminal, and the apparatus comprises:
a processor;
a memory configured to store instructions executable by the processor;
wherein the processor is configured to:
configure a power saving signal for the terminal when determining that it is required to instruct the terminal to perform BWP switching, the power saving signal being a wake up signaling (WUS), and the WUS being configured to instruct to perform a BWP switching; and
transmit the power saving signal to the terminal, to allow the terminal to perform the BWP switching based on the power saving signal;
wherein the processor is configured to transmit the WUS signaling to the terminal, to allow the terminal, in response to the WUS not comprising first information for representing a first designated BWP, to determine 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; to switch a currently activated BWP to the first target BWP; and to perform at least one of physical downlink control channel (PDCCH) monitoring or physical downlink shared channel (PDSCH) monitoring on the first target BWP; and
wherein the processor is configured to transmit the WUS signaling to the terminal, to allow the terminal, in response to the WUS comprising the first information for representing the first designated BWP, to determine the first designated BWP for switching based on the first information; switch the currently activated BWP to the first designated BWP; and to perform at least one of PDCCH monitoring or PDSCH monitoring on the first designated BWP; wherein the first designated BWP being a target BWP for switching and configured by the base station for the terminal.
