1. A method for controlling activation of a bandwidth part (BWP), comprising:
receiving BWP configuration information transmitted by a base station;
receiving a primary cell handover command transmitted by the base station, wherein the primary cell handover command is configured to indicate a target primary cell for handover and a default BWP on the target primary cell; and
performing a cell handover based on the default BWP on the target primary cell and the target primary cell;
wherein the BWP configuration information comprises BWP configuration information of a primary base station and BWP configuration information of a secondary base station;
when the BWP configuration information of the secondary base station is received, the BWP configuration information of the secondary base station is used to indicate a component carrier where a primary cell of the secondary base station is located, and default BWP information corresponding to each component carrier; and
after receiving the BWP configuration information transmitted by the base station, the method further comprises:
activating a default BWP corresponding to the component carrier where the primary cell of the secondary base station is located.
