Abstract
A system and method of increasing data throughput in a wireless communications network between a base station (BS) and one or more mobile stations (MS) includes establishing a service flow (SF) and initially enabling a hybrid automated repeat request (HARQ) protocol; determining, at a particular time, the measure of quality of the communications channel; comparing the determined measure of quality with a predetermined channel quality threshold; and selectively disabling the HARQ protocol based upon a first comparison result while continuing the SF between the BS and MS. In other aspects, after selectively disabling the HARQ protocol, the method further includes determining that the time-varying measure of quality of the communications channel has deteriorated below the predetermined channel quality threshold; and selectively re-enabling the HARQ protocol in the established SF.
