<p>In a wireless communication system in which a base station apparatus 3 and a mobile station apparatus 1 communicate with each other, the base station apparatus 3 sets the number of spatial multiplexing sequences (rank) of data, which is the number being used by the mobile station apparatus when the mobile station apparatus transmits a PUSCH, further sets orthogonal resources used by the mobile station apparatus 1 respectively for the same number of reference signals as the set number of spatial multiplexing sequences which are transmitted together with the PUSCH, and transmits downlink control information including information indicative of the set number of spatial multiplexing sequences and information indicative of the orthogonal resources used for the reference signals, and the mobile station apparatus 1 receives the downlink control information, selects orthogonal resources to respectively apply to the same number of reference signals as the number of spatial multiplexing sequences indicated by the information indicative of the number of spatial multiplexing sequences from the information indicative of the orthogonal resources, applies the selected orthogonal resources to generate the reference signals, and transmits the generated reference signals to the base station apparatus 3.</p> |
