摘要： In various embodiments, a system and method for providing uplink (UL) power control for a wireless mobile station (MS) includes, after transmission of an unanswered bandwidth request by the MS, incrementally boosting an UL transmit power of one or more subsequent bandwidth requests by the MS to a boosted UL power level at which UL bandwidth is allocated to the MS by the BS; selectively reporting the boosted UL power level to the BS immediately after the UL transmit power has been boosted; and selectively controlling the boosted UL power level by the BS responsive to the boosted UL power level reported to the BS. A MS is configured to carry out the UL power control method and a BS is configured to generate MS UL power control commands based, at least in part, upon the UL power level reported to the BS.

摘要： A plurality of ranging processes are performed to monitor a status of a wireless link associated with a device identifier. A ranging request that includes the device identifier and a message skip indicator is received. It is determined that the device identifier is already associated with the wireless link. A duration since a previously completed ranging process is determined. Based on the duration, and the message skip indicator, it is determined whether to respond to the ranging request.

摘要： 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.

摘要： A system and method for adaptive control of an averaging parameter in a communications network may include an averaging parameter adaptive control module (APAC) that is associated with a base station and that includes one or more processors configured to generate a first averaging parameter that is transmitted by the base station to a mobile station communicating with the base station. The mobile station may use the first averaging parameter to generate first channel condition information that indicates a condition of a communication channel. First feedback information including the first channel condition information may be received at the base station. The APAC may generate a second averaging parameter using the first averaging parameter and the first feedback information and may transmit the second averaging parameter from the base station to the mobile station, thereby adaptively controlling the second averaging parameter based on the first feedback information.
