摘要

PROBLEM TO BE SOLVED: To support Localized type transmission and Distributed type transmission by one system. SOLUTION: A system band is divided into plural pieces by frequency blocks which are formed by a plurality of continuous frequency subcarriers, while a frequency scheduling unit for selecting a frequency block to be assigned to a downlink channel and a mapping unit for mapping data of the downlink channel into the selected frequency block in the frequency scheduling unit are provided. The frequency scheduling unit sequentially selects the frequency blocks in accordance with a previously determined pattern in which the frequency block is to be disposed by being distributed by a fixed interval into the system band in response to elapse of times.
