ABSTRACT:
A communication system and method adaptively control frequency ranges of a pair of interconnected transceivers in an effort to enhance the data rate in one direction. In this regard, a full duplex communication session is established between a first transceiver and a second transceiver. Signals having frequencies within an overlapping bandwidth are communicated between the first and second transceivers during a data phase. A transmission capacity of one of the transceivers is determined based on the communicated signals, and a comparison between this transmission capacity and a specified transmission capacity for the one transceiver is performed. A portion of the overlapping bandwidth is adaptively selected based on the comparison, and the one transceiver is prevented from transmitting signals having frequencies within the selected portion of the bandwidth during the data phase.
