COMMUNICATION SYSTEM, COMMUNICATION METHOD, BASE STATION APPARATUS, AND TERMINAL APPARATUS

摘要

The objective of the invention is to improve the frequency use efficiency, while suppressing the interference between cells. Provided is a communication system (1) in which a plurality of communication areas, in each of which a base station apparatus communicates with at least one terminal apparatus, are existent and are adjacent to or overlap with each other. In the communication system (1), a macrocell base station apparatus (100) in one of the plurality of communication areas allocates terminal apparatuses of the plurality of communication areas to the same frequency band, and calculates transmission and reception weights for the terminals, which are allocated to the same frequency band, to perform cooperative controls of each other.
