Abstract: The present disclosure provides a method for measuring an amount of interference from an antenna, the method comprising the operations of: receiving at least on reference symbol; calculating a reference symbol NI, which is the antenna-related noise interference (NI) in the at least one reference symbol, on the basis of the at least one reference symbol; receiving at least one data symbol; calculating a data symbol NI, which is the antenna-related NI in the data symbol, on the basis of the at least one data symbol; calculating an NI ratio of the antenna which is the ratio of the data symbol NI relative to the reference symbol NI; and determining an antenna weight of the antenna on the basis of the NI ratio.

Abstract: An interference cancellation method and apparatus of a base station is provided for use in a wireless communication system, which includes receiving a first signal by a first antenna and a second signal by a second antenna, measuring interference amounts in the first signal and the second signal based on a result of channel measurement performed on the first signal and the second signal, and generating a third signal as a target of decoding by adjusting channel parameters associated with channel conditions of the first antenna and the second antenna based on the measured interference amounts. The channel parameters are generated based on the channel measurement result.
