USER DEVICE AND USER ALLOCATION INFORMATION ESTIMATION METHOD

摘要

Provided is a user device which is used in a wireless communication system including a plurality of base stations, and which has a function of carrying out interference reduction on the basis of user allocation in an interference cell, said user device comprising: an interference pattern generating means for generating a plurality of interference patterns which are combinations of whether interference signals are present in a prescribed number of interference cells with respect to the user device; a reception quality computation means for computing reception quality after interference reduction in the interference patterns in each of the plurality of interference patterns which are generated by the interference pattern generating means; and a user allocation information estimation means for treating the presence or absence of an interference signal in each interference cell corresponding to the interference pattern which is the basis of the best reception quality among the reception qualities which are computed by the reception quality reception means as the presence or absence of the user allocation.
