Abstract
A data communication apparatus, which can eliminate delay in transmission of information that responds to receive information from a base station and which can expand the radius of a communication zone of the base station at a mobile station. A base station 100 that comprises the present apparatus allocates a slot 124 for other mobile station between both a downlink slot 122 and an uplink slot 123 for the same mobile station in the same frame at the time of carrying out scheduling that allocates both the downlink slot 122 and the uplink slot 123 to each mobile station in accordance with downkink/uplink traffic loads.
