ABSTRACT:
A method of data communication. The method includes initially receiving one or more channel quality information signals from each wireless unit. The channel quality information may be received in response to the transmission of one or more pilot signals. Once the channel quality information signal(s) from each wireless unit are received, the method then includes selecting one or more transmit powers and one or more transmission rates for each wireless unit. Thereafter, one or more blocks of orthogonal continuous waveforms may be transmitted over a channel to each wireless unit using the selected transmit power and selected transmission rate.
