TRANSMISSION APPARATUS AND COMMUNICATION METHOD

摘要

In an OFDM down-stream wireless access, a transmitting device (10) for mu ltiplexing control channels for a plurality of receiving devices with same t ransmitting timing OFDM symbols is comprised of a pattern generating unit (1 01) for generating frequency mapping patterns inherent in a transmitting dev ice and a frequency allocating unit (103) for allocating control channels fo r a plurality of the receiving devices to subcarriers in accordance with the frequency mapping patterns inherent in the transmitting device.
