Abstract: Briefly, in accordance with one or more embodiments, a distributed simultaneous transmit and receive system implements relaying without incurring the additional overhead associated with relaying and without requiring additional isolation techniques to isolate the transmit and receive circuits of the relay stations. During a first transmission resource, a base station transmits to a first relay station while a second relay station transmits to one or more mobile stations associated with the second relay station. During a second transmission resource, the base station transmits to the second relay station while the first relay station transmits to one or more mobile stations associated with the first relay station.

Abstract: A data rate is selected for subcarriers of each frequency and spatial channel of a slowly varying frequency selective multicarrier channel to provide uniform bit loading (UBL) for faster link adaptation. Signal to noise ratios (SNRs) for subcarriers of the multicarrier communication channel may be calculated from channel state information and a transmit power level. A throughput may be estimated for the data rates from the SNRs and one of the data rates may be selected based on the estimated throughputs.
