`
`A radio Communication method for exchanging information
`between a base station and a terminal station. The method
`includes: communicating the information between the base
`station and the terminal station b multi carrier si nals b
`.
`.
`y .
`g
`. y
`OFDM modulation scheme Including plural subcarriers
`a
`Communicating Control Signals in addi_
`tion to the information between the base station and the ter
`minal station, and wherein part of the control signals
`addressed to the terminal station from the base station is
`transmitted by one or more speci?c subcarriers in the band
`width for the multi-carrier signals.
