Methods and apparatus for performing self-interference cancellation in a wireless communication system

Abstract

The disclosure relates to a 5th generation (5G) or 6th generation (6G) communication system in wireless communication. A method for a base station supporting flexible duplex communication by dynamically allocating uplink and downlink resources for the same frequency band in a wireless communication system includes transmitting a pilot signal for estimating non-linearity of an SI channel through which a signal transmitted by the base station is received by the base station; estimating non-linearity of the SI channel based on the pilot signal received through the SI channel; correcting and transmitting a DMRS, which is used for demodulating a signal received by a terminal from the base station, based on the estimated non-linearity of the SI channel; estimating the SI channel based on the corrected DMRS received through the SI channel; and performing communication with a plurality of terminals by cancelling SI based on the estimated SI channel.
