Abstract
A base station includes a channel quality detecting unit that detects channel quality between the base station and a mobile station, a buffered data amount monitoring unit, and a modulation and coding set determination unit. The modulation and coding set determination unit determines a modulation and coding set, as a downlink modulation scheme for packet communications, such that a prescribed communication condition corresponding to the channel quality is satisfied, and that padding added to the data buffered in a transmission buffer for subsequent transmission to the mobile station becomes the minimum.
