Abstract: To solve a problem that although the increase of the number of frequency blocks by allocating discontinuous subcarriers (RBs) as in OFDM enables an increase in multi-diversity effect and an improvement in throughput, the number of RB allocation patterns increases with the increase of the number of frequency blocks, resulting in an increase in the amount of information relating to the allocated RBs, the resource block allocation unit is determined when resource blocks discontinuous on the frequency axis are allocated to a terminal, and the number of bits of scheduling information indicating the allocated resource blocks by using Tree Based is set to the number of bits corresponding to the determined allocation unit.

Abstract: A base station includes a transmitter configured to transmit a downlink control information to a user equipment, the downlink control information being generated based on one of (1) a first uplink allocation information indicating a first frequency block corresponding to a first plurality of subcarriers which are contiguous in frequency and (2) a second uplink allocation information indicating a second frequency block corresponding to a second plurality of subcarriers which are contiguous in frequency and a third frequency block corresponding to a third plurality of subcarriers which are contiguous in frequency, the second frequency block and the third frequency block being separated in frequency.
