Abstract
To notify the control information necessary for uplink MIMO transmission while reducing overhead, generated is a UL grant having the PMI/RI field and non-transmission/swap flag field of 1 bit indicative of a transport block made non-transmission and the presence or absence of a swap of control information between two transport blocks corresponding to a value of the PMI/RI field, a downlink control channel signal including the UL grant is transmitted to a mobile station apparatus, and the transport block made non-transmission and the presence or absence of a swap of control information between two transport blocks is determined from the non-transmission/swap flag of the UL grant.
