Abstract
The present disclosure relates to a pre-5th-generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-generation (4G) communication system such as long term evolution (LTE). A method of operating a base station for interference cancellation in a wireless communication system is provided. The method may include receiving, from a target terminal, an uplink data signal including at least one interference signal generated by at least one interference terminal; performing a primary decoding for the uplink data signal; in accordance with decoding errors, generating a cancelling signal corresponding to an interference signal of the at least one interference terminal; performing a cancellation by applying the cancelling signal to the uplink data signal; and performing a secondary decoding for the uplink data signal to which the cancelling signal has been applied.
