Title: USER DEVICE AND INTERFERENCE REDUCTION PROCESSING METHOD
Abstract:
A user device used in a radio communication system is provided with: an interference reduction processing unit which acquires a desired signal from a received signal that is received by the user device by reducing an interference signal that becomes interference for the desired signal; and an interference reduction processing implementation determination unit which measures the reception quality of the interference signal, and on the basis of the reception quality, determines whether the interference signal is subjected to interference reduction processing or not. The interference reduction processing implementation determination unit determines whether the interference signal is subjected to the interference reduction processing or not by comparing a first index value of the interference signal, which is estimated from the reception quality, and a second index value used for the transmission of the interference signal.
