Method for controlling activation of bwp, user equipment and base station

A method for controlling activation of a bandwidth part (BWP), comprising:

• transmitting BWP configuration information to a user equipment;
• wherein the BWP configuration information is used to indicate a default BWP corresponding to each component carrier;
• and
• wherein after transmitting the BWP configuration information to the user equipment, the method further comprises:
• transmitting a component carrier deactivation signaling to the user equipment, wherein the component carrier deactivation signaling is configured to instruct the user equipment to deactivate a third target component carrier, or to deactivate a third target component carrier and all activated BWPs on the third target component carrier.

A user equipment, comprising:

• one or more processors;
• a memory;
• and
• one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the one or more processors, and when executing the one or more programs, the one or more processors are configured to:
• receive BWP configuration information transmitted by a base station;
• wherein the BWP configuration information is used to indicate a default BWP corresponding to each component carrier;
• and
• the one or more processors are further configured to:
• receive a component carrier deactivation signaling transmitted by the base station;
• and
• deactivate, based on the component carrier deactivation signaling, a third target component carrier, or a third target component carrier and all activated BWPs on the third target component carrier.
