Provided are a radio transmission apparatus, a radio reception apparatus, and a communication method capable of realizing a radio LAN system in which user throughput is improved by using OFDMA while suppressing overhead. A radio transmission apparatus of the invention selects any one group from a plurality of groups each indicating a combination of a plurality of radio reception apparatuses, notifies at least a plurality of radio reception apparatuses belonging to the selected group of an identification number assigned in advance to the selected group, and allocates transmission data addressed to the radio reception apparatuses belonging to the selected group to each of a plurality of frequency resources on the basis of order of the radio reception apparatuses, which is determined in advance in the selected group.
