    摘要： Provided is a radio resource allocation method of allocating common radio resources shared among a plurality of radio stations or a plurality of sectors to each of the plurality of radio stations or each of the plurality of sectors. The method includes defining, as a frame set, a given number of radio frames for repeatedly providing the common radio resources along a time axis, defining, as radio resource units, minimum units obtained by dividing the common radio resources provided by the frame set in units of the radio frames and in units of sub-channel groups, and allocating at least one of the radio resource units to each of the plurality of radio stations or the each of the plurality of sectors.

    摘要： In a radio communication system, when switching of a multicast communication and a unicast communication is performed, a radio communication base station determines whether to switch a communication mode based on reception information received from a mobile terminal, newly establishes a logical channel between the mobile terminal and the radio communication base station by the same logical channel as before switching based on the determination result, converts to a transport channel of a communication mode different from before switching in the newly established logical channel, and switches communication with each mobile terminal to a communication mode represented by the converted transport channel. Thus, switching of the communication mode is performed limitedly only in between the radio communication base station and each mobile terminal.
