RADIO COMMUNICATION DEVICE AND MULTICHANNEL COMMUNICATION SYSTEM

摘要

It is possible to effectively transmit reception quality information required when performing an adaptive modulation process or an adaptive channel allocation and allocate a sufficient resource to be used for actual communication. A mobile station (100) measures reception quality information on a plurality of communication channels, performs a two-dimensional conversion process on the reception quality information on each of the communication channels, reduces or deletes a part of spatial frequency after the two-dimensional conversion process, and generates quality report information by using the data after the reduction or the deletion. A base station (200) adds dummy data to a part corresponding to the spatial frequency reduced or deleted when generating the quality report information, performs an inverse two-dimensional conversion process on the quality report information after the addition, and uses the data after the inverse two-dimensional conversion process as a plurality of reception quality information so as to perform, for example, slot allocation and an adaptive modulation process.
