circuitry, which, in operation, allocates resource blocks, each of which is comprised of consecutive subcarriers in a frequency domain, to a terminal in one of a plurality of resource allocations including:
a resource allocation allocating Distributed Virtual Resource Blocks (DVRBs), a pair of DVRBs assigned by a single resource block number being mapped to Physical Resource Blocks (PRBs) with a gap in a frequency domain, the gap being an integer multiple of a Resource Block Group (RBG) size defined as a number of one or more consecutive PRBs comprising one RBG, the gap and the RBG size being associated with a system bandwidth; anda resource allocation allocating one or more RBGs; and a transmitter, which, in operation, transmits data using the allocated resource blocks to the terminal. |
