Abstract
A method is described for scheduling a plurality of data flows to a plurality of shared channels in a wireless communication system transmitting data packets in time intervals of frames and applying adaptive modulation and coding. The method comprises the steps of determining virtual link adaptation parameters for at least a part of all combinations of data flow and shared channel, based on state information from the respective shared channel, and based on Quality of Service requirements for the respective data flow; calculating potential data rates for said combinations of data flow and shared channel, based on said virtual link adaptation parameters; calculating priority values for said combinations of data flow and shared channel, based on said potential data rates; and selecting, based on the calculated priority values, for at least a part of the shared channels, a data flow for which data is to be transmitted on each of these shared channel during the time interval of one frame.
