Claim 12:
13. 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 go-to-sleep signal (GTS), and the GTS being configured to instruct to perform a BWP switching; and
transmit the power saving signal to the terminal, to allow the terminal to perform to BWP switching based on the power saving signal;
wherein the processor is configured to transmit the GTS to the terminal to allow the terminal, in response to the GTS not comprising second information for representing a second designated BWP, to determine a second target BWP for returning based on a second setting rule when the terminal is not configured with a BWP inactivity timer, wherein the second setting rule is transmitted by the base station to the terminal through system messages or dedicated signaling; and to return from a currently activated BWP to the second target BWP; and
wherein the processor is configured to transmit the GTS to the terminal to allow the terminal, in response to the GTS comprising the second information for representing the second designated BWP, to determine the second designated BWP for returning based on the second information; and to return from the currently activated BWP to the second designated BWP; wherein the second designated BWP is a target BWP for returning and configured by the base station for the terminal.
