Radio communication system, radio transmission apparatus, and resource allocation method

摘要

Provided is a resource allocation method capable of improving a reception quality when connecting a plurality of sub frames into one frame and performing a communication process for each of the frames. In this method, when a sub frame #1 is transmitted, LRB is selected as a resource allocation format according to CQI fed back from a mobile station and RB having a preferable propagation quality is allocated for transmission data according to the LRB format. When a sub frame #2 is transmitted, the same resource allocation method (LRB) as the head sub frame is used and the transmission data is allocated for the same RB. When a sub frame #3 is transmitted, the resource allocation method is switched from the sub frame #1 and the sub frame #2 and the transmission data is allocated for RB by using the DRB format.
