Abstract
Abstract A communications system is provided. A first communications device requests one or more dedicated service periods, via a request, to transmit a high rate real-time streaming data. A second communications device receives the request and schedules the dedicated service periods and one or more contention based periods. A third communications device receives the high rate real-time streaming data and requests the first communications device to re-transmit a portion of the high rate real-time streaming data. The request includes information about the high rate real-time streaming data and information pertinent to a probability of re-transmission. The contention based periods are scheduled to provide the first communications device having higher priority over communications devices of the communications system. The first communications device transmits the high rate real-time streaming data using the dedicated service periods, and re-transmits the portion of the high rate real-time streaming data using the contention based periods.
