Abstract
An interference cancelling station ICS includes a transmission weight factor calculating unit calculating a transmission weight factor w2 and an interference cancelling data signal transmitting unit generating an interference cancelling data signal by multiplying, by the transmission weight factor w2, a data signal transmitted by a base station BSb of the wireless communication system B and transmitting the interference cancelling data signal in synchronization with timing with which the base station BSb of a wireless communication system B transmits the data signal, and a mobile station MSa of a wireless communication system A receives a data signal transmitted by a base station BSa of the wireless communication system A, the data signal having cancelled interference from the base station BSb of the wireless communication system B.
