Title: WIRELESS COMMUNICATION SYSTEM, BASE STATION APPARATUS AND MOBILE STATION APPARATUS
Abstract:
When two or more types of information of required qualities, which are different in allocated communication resources, are to be transmitted, communications can be performed which efficiently and simply satisfy the required qualities. A base station apparatus (200), which uses a MIMO (Multiple Input Multiple Output) system to transmit/receive, to/from mobile station apparatuses, a plurality of types of signals having different required qualities, comprises: an uplink spatial multiplexing information control unit (222) that selects, in accordance with the required qualities of signals, respective different numbers of spatial multiplexing sequences; an uplink modulation scheme/coding rate control unit (223) that selects, in accordance with the required qualities of the signals, at least either respective different modulation schemes or coding rates; and a transmission unit (210) that transmits, to the mobile station apparatuses, information indicating the selected numbers of spatial multiplexing sequences as well as information indicating the selected modulation schemes or coding rates.
