SETTING METHOD FOR SYSTEM BANDWIDTH, WIRELESS COMMUNICATION SYSTEM, BASE STATION AND PROGRAM

WIPO Patent Application WO/2013/146320

A1

The invention of the present application addresses the providing of a technique for setting system bandwidth which improves system capacity of a base station or throughput of a mobile station by way of application of MU-MIMO. The invention of the present application is an invention for setting system bandwidth which can be used by a base station for performing wireless communication with a plurality of mobile stations in a wireless communication system which uses a plurality of system bandwidths, the invention being characterized in that, with respect to mobile stations belonging to the same base station, system bandwidth used for communication by each base station is set, communication quality information for the set system bandwidth is acquired, and on the basis of the acquired communication quality information, the system bandwidth that has been set for each mobile station is re-set so as to reduce interference among terminals.
