Base station apparatus and transmission branch selection method

摘要

Level detectors 305 to 312 detect reception levels of uplink bursts received by their respective subcarriers/branches, then interpolation sections 313 to 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 this selected branch.
