A wireless base station (2) controls to decrease a transmission power of a first wireless terminal (3) corresponding to signal quality information exceeding lower limitation of a range in which a transmission scheme to be selected remains unchanged and below a first threshold value, which is greater than the lower limitation and smaller than upper limitation of the range, among a plurality of wireless terminals (3) corresponding to signal quality information belonging to the range, while controlling to increase a transmission power of a second wireless terminal (3) corresponding to signal quality information equal to or greater than the first threshold value so that a transmission scheme having a better transmission efficiency is selected, thereby to improve throughput of a communication between the wireless base station (2) and the wireless terminal (3). |
