<P>PROBLEM TO BE SOLVED: To provide a radio communication apparatus wherein an overhead by a header is reduced, efficiency is improved, and further which can properly be adapted to an IP packet of a widely distributed size, and to provide a method for mapping. <P>SOLUTION: A radio communication apparatus is provide which performs the 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 the mapping of the spread channel coding block in a wireless frame composed of a frequency block and a TTI. <P>COPYRIGHT: (C)2007,JPO&INPIT |
