Abstract:
1. A wireless system comprising: a transmitter for wirelessly transmitting data units according to physical transmission parameters including transmission bit rate, wherein the physical transmission parameters have values associated with different error rates in transmitting the data units using the physical transmission parameters; a transmitter controller receiving data units for transmission and evaluating a time varying usefulness of the data units in conveying information of a communication flow of multiple data units, the transmitter controller providing each data unit to the transmitter for transmission together with associated physical transmission parameters for the data unit based on the usefulness of the data unit, wherein data units having higher usefulness are associated with physical transmission parameters having lower error rates, and data units having lower usefulness are associated with physical transmission parameters having higher error rates; whereby the physical transmission parameters of the data units changes within a communication flow; wherein the physical transmission parameter provided to the transmitter is based on a functional combination of a base rate selected for a group of data units and a physical transmission parameter independent to a data trait within the communication flow and wherein the transmitter further receives client reception reports providing an indication of errors in received data units and wherein the base rate for each data unit is adjusted based on the client reception reports.
