摘要

A control information channel signal formation unit has a channel encoding section and a spreading section. The channel encoding section multiplexes a plurality of types of control information for a single communication terminal for use in uplink packet transmission, using different symbol patterns between a plurality of types of control information. The spreading section spreads symbols obtained by the channel encoding section using one spreading code.
