TRANSMISSION DEVICE AND TRANSMISSION METHOD.

摘要

A transmission device includes: frequency scheduling means for allocating to each user, a frequency block obtained by dividing a system bandwidth into continuous frequency sub carriers or a distributed frequency block obtained by discretely distributing frequency sub carriers within a system bandwidth; and mapping means for allocating transmission data to one of the localized frequency block and the distributed frequency block according to the allocation. The scheduling means allocates the distributed frequency block on the basis of the frequency block so as to allocate divided blocks obtained by dividing the distributed frequency block into a plurality of blocks.
