Efficient radio communication is implemented in a usage pattern desired by users. A cellular phone as mobile radio communication apparatus communicates by air with a base station as fixed radio communication apparatus (Step S1). When the cellular phone detects that the cellular phone is positioned at the fringe of the cell of the base station (Step S3), the cellular phone independently makes adjustment to lower the transmission power according to the judgment of the cellular phone itself in correspondence with the received power from the base station (Step S11). Further, the cellular phone lowers the bit rate of transmission data in correspondence with the adjusted transmission power (Step S12). The present invention is applicable to information processors, such as cellular phones, PDAs, and mobile terminals, provided with a radio communication function.
A radio communication system wherein fixed radio communication apparatus and mobile radio communication apparatus communicates by air with each other, and wherein
