    摘要： A mobile communication system in which, when transmission is performed from a base station to a terminal device, a modulation scheme is designated, from among at least two modulation schemes with different modulation levels, on the basis of reception quality at the terminal to perform transmission from the base station. The system includes a base station transmitting at a first transmission power using a frequency designed for, in a channel allocation scheme of the system, not causing interference with an adjacent base station and using a first modulation scheme, and a second channel transmitting at a second transmission power lower than the first transmission power, and when the base station uses the second channel, a second modulation scheme having a lower modulation level than the first modulation scheme is designated, and communication is performed.

    摘要： A mobile communication terminal (UE) comprises: a transmitting unit (213, 211) which transmits a signal via a radio resource allocated to the mobile communication terminal (UE) for the transmission of a prescribed control signal; and a signal selector unit (214) which, when upstream traffic occurs, selects a reservation request signal as the signal to be transmitted via the allocated radio resource wherein, when the mobile communication terminal (UE) is in a standby state, the reservation request signal is transmitted from the mobile communication terminal (UE) to the base station (BS) by using the radio resource allocated to the mobile communication terminal (UE) for the transmission of the prescribed control information.

    摘要： For transmitting predetermined information to a second communication station via a first communication station, the second communication station receives the predetermined information via one first communication station from among a plurality of the first communication stations. Upon transfer of a function of transferring the predetermined information to the second communication station to another first communication station, the another first communication station receives the predetermined information from the one first communication station, and transfers the same to the second communication station, with attaching distinction information to the predetermined information for distinguishing between the predetermined information transferred to the second communication station via the another first communication station and the predetermined information received from the another first communication station directly.

    摘要： A wireless communication system comprises a mobile station and a base station, which use a plurality of communication channels and a pilot channel corresponding to at least one of the communication channels. The base station has a transmitting unit that employs at least one of the communication channels as a priority channel and transmits channel information of this priority channel and the other channels by use of a communication channel other than the pilot channel. The mobile station has a determining unit that determines a reception level of the pilot channel; an acquiring unit that acquires the channel information transmitted via the communication channel other than the pilot channel; and a deciding unit that decides, as an available communication channel, at least one of the communication channels based on both the channel information acquired by the acquiring unit and the reception level determined by the determining unit.
