摘要： 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.

摘要： Under a multi-cell radio communication environment where connection between cells or TDMA frame synchronization is not established, a mobile station carries out an adjacent cell search under low power consumption. Adjacent cell information acquired through search by the mobile station is managed centered on a base station and may be provided by the base station as adjacent cell information, when the mobile station carries out the adjacent cell search. The adjacent cell information includes, for example, a TDMA frame offset between cells so that the mobile station receives a broadcast channel of the adjacent cell at appropriate timing based on the adjacent cell information and therefore does not need to perform unnecessary reception operation in the event of a handoff.

摘要： A control information transmitting method for controlling transmission power, wherein a control symbol obtained by assigning control information for controlling transmission power to symbols of phase modulation is transmitted to a communication partner so as to control the transmission power of the communication partner, the control information which represents raising the transmission power of communication partner and the control information which represents lowering the transmission power of the communication partner are assigned to a pair of symbols having the longest Euclidian distance among the symbols of phase modulation. Whereby, even if receiving noise or interference are present during transmission, the control information can be prevented from being misjudged because the distance on the signal constellation is farthest apart from each other, so that the control information can be transmitted exactly.

摘要： When multiplexing channels which conduct communication at various transmission rates, each communication is made capable of conducting communication processing, such as information reception, with a minimum required processing amount needed by itself. A plurality of communication channels are set in a predetermined band, and communication in each of the set channels is performed by using a multi-carrier signal having transmission symbols distributed among a plurality of subcarriers. Transmission symbols of each channel on a frequency axis are arranged at intervals of an Nth power of 2 (where N is an arbitrary positive number) with respect to a reference frequency interval for transmission. From the transmission signal, a signal component of a required channel is received.
