TRANSMISSION DEVICE, RECEIVING DEVICE, TRANSMISSION METHOD AND RECEIVING METHOD

摘要

A base station (100) transmits a DL grant for a terminal (200) by mapping it to an R-PDCCH region, thus transmitting a series of data groups to the terminal (200) by the SPS method. A transmission control unit (102) sets in the R-PDCC H region a control resource region which maps a data resource and the DL grant i n a resource block group common in frames to be transmitted by the SPS method. A resource region which was defined as a control resource region in a first fram e to be transmitted among a plurality of frames to be transmitted is defined as a d ata resource in a second or subsequent frame to be transmitted.
