PURPOSE:To improve frequency use efficiency for channel assignment of mobile communication. CONSTITUTION:In a time division multiplexing/multiple access system (TDMA /TDD), a base station which retrieves idle channels compares a level U1 of the interference wave received by the slot of the radio channel, which the base station will use for transmission, and a level U2 of the interference wave received by the slot, which a mobile station as the other party of communication will assign for transmission, with each other and raises a priority level fp of this channel or the frequency including this channel in the case or U1>U2 put reduces it in the case of U1(U2 and successively retrieves idle channels in the order from the channel or the frequency having the highest priority in response to a request of channel assignment.
