The application relates to a method, a base station (BS), a user equipment (UE) and a system thereof for channel switching. The method includes: receiving, from the UE, information indicating that the UE has a full-duplex communication capability; transmitting, to the UE, control signaling notifying the UE to activate the full-duplex communication capability; and scheduling full-duplex transmission for the UE after the UE completes initialization of a self-interference cancellation module, wherein, the base station further configures a full-duplex mode timer and notifies the UE of configuration of the full-duplex mode timer. The present disclosure provides a base station, an apparatus and operation methods thereof for performing interference processing in a wireless communication system. The base station is configured to allocate resources for a plurality of apparatuses communicating with the base station based on a level of inter-apparatus interference among the plurality of apparatuses; and to indicate the allocated resources to the plurality of apparatuses. The apparatus is configured to acquire, from a base station, resources allocated for the apparatus by the base station based on a level of inter-apparatus interference among a plurality of apparatuses communicating with the base station; and to communicate based on the allocated resources.
