Radio communication apparatus and subcarrier assignment method

摘要

Wireless communication apparatus capable of increasing transmission efficiency by selecting data for scheduling according to data type, and capable of achieving low power consumption and high-speed signal processing is disclosed. With this apparatus, a control section ( 108 ) allocates transmission data sequence 1 to subcarriers of superior quality by carrying out scheduling for the transmission data sequence 1 based on CQI sent from communication terminal apparatus and required transmission rate information for each communication terminal apparatus, and allocates transmission data sequence 2 to preassigned subcarriers. Channel allocation section ( 115 ) allocates data for transmission data sequence 1 to subcarriers designated by control section ( 108 ). Channel allocation section ( 116 ) allocates data for transmission data sequence 2 to subcarriers designated by control section ( 108 ).
