Abstract:
1. A communication control method comprising: generating a UL grant having a field for PMI (Precoding Matrix Indicator)/RI (Rank Indicator) information, and another field for a non-transmission/swap flag 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 field for PMI/RI information; transmitting a downlink control channel signal including the UL grant to a mobile station apparatus; and determining the transport block made non-transmission and the presence or absence of a swap of control information between two transport blocks from the non-transmission/swap flag of the UL grant, wherein, when the value of the field for PMI/RI information is a predetermined value or less, the transport block made non-transmission is determined corresponding to the value of the non-transmission/swap flag, and when the value of the field for PMI/RI information is more than the predetermined value, the presence or absence of a swap of control information between two transport blocks is determined corresponding to the value of the non-transmission/swap flag.
