RADIO COMMUNICATION APPARATUS AND SUBCARRIER ASSIGNMENT METHOD

摘要

A radio communication apparatus wherein data to be scheduled are selected according to data type so as to improve the transmission efficiency, reduce power consumption and realize a high- speed signal processing. In the apparatus, a control part (108) schedules a transmission data sequence (1) based on both CQI received from communication terminal apparatuses and the request transmission rate information of each of the communication terminal apparatuses, thereby assigning the transmission data sequence (1) to a subcarrier of a good quality and also assigning a transmission data sequence (2) to a predetermined subcarrier. A channel assigning part (115) assigns the data of the transmission data sequence (1) to a subcarrier designated by the control part (108). A channel assigning part (116) assigns the data of the transmission data sequence (2) to a subcarrier designated by the control part (108).
