Title:

INTERFERENCE CANCELLATION METHOD AND BASE STATION APPARATUS THEREFOR

Document Type and Number:

WIPO Patent Application WO/2016/163790

Kind Code:

A1

Abstract:

Various embodiments of the present invention relate to a method and an apparatus for canceling interference signals from a terminal of a neighboring cell in a cellular communication system, and the operational method of a base station for interference cancellation may comprise the steps of: receiving, from a target terminal, an uplink data signal comprising at least one interference signal generated by at least one interfering terminal; primarily decoding the uplink data signal; in accordance with decoding errors, generating at least one dominant interference signal corresponding to an interference signal of at least one interfering terminal; canceling at least one dominant interference signal from the uplink data signal; and secondarily decoding the uplink data signal from which at least one dominant interference signal has been canceled.
