<p>In a CDMA communication system where each radio slot has a plurality of short slots, a radio control apparatus allows a plurality of mobile stations using a single channelization code for communication with a radio base station apparatus to share the same radio slot by allocating different short slots to the plurality of mobile stations in its cell. The radio control apparatus includes a short slot storage unit for storing the usage status of a short slot which has been allocated already; a short slot selection unit for selecting a single unoccupied short slot for a new radio link between a new mobile station and the radio base station apparatus, in accordance with the usage status; and a transmission timing determination unit for randomly determining the radio transmission timing of a radio frame used for communication in the new radio link, in accordance with the selected short slot, such that the timing does not overlap with the radio transmission timing used by an existing link.</p> |
