According to a communications method according to the present invention, data is transmitted from a base station to two or more terminals via a common channel, and transmission power, with which the data is transmitted from the base station to the two or more terminals, is controlled according to a reception state of at least one of the two or more terminals. Furthermore, the terminal transmits reception capability information at a time of selection combining, and at least one of the two or more base stations receives the reception capability information at the time of selective combining and notifies the reception capability information to a radio network controller (RNC) which controls the two or more base stations. When a connection request is issued to the terminal, the RNC refuses assignment of a dedicated channel to the connection request when determining that the assignment of the dedicated channel to the terminal cannot be done based on the reception capability information at the time of selective combining.
