Patent ID: 10187168

Abstract:
Provided is a method for performing network assisted interference cancellation and suppression (NAICS) in user equipment (UE) in which a carrier aggregation (CA) is set. The method can comprise the steps of: receiving a UE capability request message; and transmitting UE capability information by responding to the UE capability request message. The UE capability information can include information related to an NAICS operation in a situation in which a CA is set. The method can comprise a step of receiving interference cancellation support information from a base station. The interference cancellation support information can include information on neighboring cells identified by respectively operating in one or more carriers which are selected by the base station on the basis of the transmitted UE capability information. The method can comprise a step of cancelling the interference received from the neighboring cells, on the basis of the information on the neighboring cells within the interference cancellation support information.
