Patent ID: 8050338

Claim:
A method of transmitting digital data symbols from a transceiver to at least two remote transceivers in a wireless communications system, said transmission employing Orthogonal Frequency Division Multiplexing, wherein a number of available sub-carriers are shared between said remote transceivers, comprising the steps of: providing information about magnitudes of Doppler effect experienced by said remote transceivers; allocating sub-carriers to each remote transceiver in dependence of said information about magnitudes of Doppler effect; and controlling a power level transmitted to each of said remote transceivers in dependence of said information about magnitudes of Doppler effect, wherein the controlling further comprises estimating from said information about magnitudes of Doppler effect a level of inter-carrier interference experienced by each remote transceiver, estimating from said estimated levels of inter-carrier interference a signal-to-noise ratio for each remote transceiver, and updating said power level transmitted to each remote transceiver in dependence of said estimated signal-to-noise ratios.
