Control channel system in mobile communication

Abstract

Abstract PURPOSE:To use a control channel frequency in common to plural base stations by allowing each subordinary base station to use an idle control channel time slot as its own station control channel in the control channel frequency of a representative base station. CONSTITUTION:Representative base stations 1-4 send synchronous signal time slots 14-1, 14-2 and their own station control channel time slots 15-1, 15-2. Subordinary base stations 5-13 use control channel frequencies among all control channel frequencies at a base station transmission band where the reception levels of the synchronous signal time slots 14-1, 14-2 are a specified value or above as their own station control channel transmission frequencies and use time slots with a reception level below the specified value among control channel times slots (15-1)-(22-1), (15-2)-(17-2) of the control channel frequency as their own station control channel time slots. Thus, plural base stations decide the use of the control channels of the same frequency rationally.
