<P>PROBLEM TO BE SOLVED: To provide a transmission apparatus and radio resource allocation method that can allocate radio resources according to types of physical channels. <P>SOLUTION: In the transmission apparatus, combinations are formed by a plurality of sub-carriers in a frequency-axis direction and a plurality of OFDM (Orthogonal Frequency Division Multiplexing) symbols in a time-axis direction; frequency blocks are formed by arranging a plurality of the combinations in a transmission slot period; and a plurality of the frequency blocks are arranged in a system frequency band; wherein a first allocation part for allocating common control channels to a top part of the OFDM symbols in a part of the frequency blocks out of the plurality of the frequency blocks, and a second allocation part for allocating common channels to the other part, different from the OFDM symbols to which the common control channels are allocated, out of the plurality of the frequency blocks arranged in the transmission slot period, are provided. <P>COPYRIGHT: (C)2009,JPO&INPIT |
