Abstract

Provided is a radio communication apparatus which performs mapping of information data in a radio frame. The radio communication apparatus is provided with a variable spreading rate control section for controlling a spreading rate; a channel coding and spreading section which performs channel coding to the information data, generates a channel coding block, and spreads the channel coding block by using the spreading rate; and a mapping section which performs mapping of the spread channel coding block in the wireless frame composed of a frequency block and a TTI.
