Claim Text:
1. A transmission apparatus comprising: an assignment unit configured to determine a frequency block to be assigned to each user, wherein the frequency block is formed by a plurality of subcarriers in a frequency domain and a plurality of OFDM symbols in a time domain, a length of the frequency block in the time domain corresponds to a transmission slot, and a plurality of frequency blocks are placed in the frequency domain over a system frequency band, each of the plurality of frequency blocks including a same number of subcarriers; and a transmission unit configured to transmit data in the frequency block determined by the assignment unit, wherein, when assigning frequency blocks for one user to two or more consecutive transmission slots, the assignment unit makes a determination so that a frequency block including the same number of subcarriers and including a plurality of OFDM symbols, and assigned to a first transmission slot and a frequency block including the same number of subcarriers and including a plurality of OFDM symbols, and assigned to a second transmission slot are continuous in the time domain and are separated by a predetermined gap in the frequency domain, wherein the assignment unit assigns a common control channel to an OFDM symbol at a head part of a part of the plurality of frequency blocks, and wherein the assignment unit assigns a channel for transmitting control information indicating a selected user to an OFDM symbol at a head part in a frequency block which is different from a frequency block to which the common control channel is assigned.
