BASE STATION APPARATUS AND TRANSMISSION BRANCH SELECTION METHOD

摘要

PURPOSE: A base station apparatus and a transmission branch selection method are provided to carry out accurate transmission branch selection even in an intermittent communication condition with a certain time interval after an uplink burst is received until a downlink burst is transmitted. CONSTITUTION: Level detectors(305-312) detect reception levels of uplink bursts received by their respective subcarriers/branches, then interpolation sections(313-320) estimate reception levels of the next uplink burst from the reception levels of a plurality of uplink bursts detected, select the branch with the maximum estimated value for each subcarrier and sends each subcarrier of the next downlink burst to be transmitted using the selected branch.
