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： An apparatus and method of configuring a number of retransmissions for an automatic repeat request (ARQ) scheme (e.g., hybrid ARQ) includes configuring one or more first maximum retransmission numbers based on respective one or more first predetermined values and independent of a second maximum retransmission number. The first maximum retransmission numbers may indicate a maximum number of retransmissions related to respective service flows operational with the base station. The second maximum retransmission number may indicate a maximum number of retransmissions related to control messages transmitted in the wireless network, and may be configured based on a second predetermined value. The configuration of the first maximum retransmission numbers may include the maximum retransmissions numbers associated with a specific user in communication with the base station. Further, at least one of the first maximum retransmission numbers of a particular user may be reconfigured to a third predetermined value.

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 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.

摘要： A method for varying pilot sub-carrier density in OFDMA communications is described. The method comprises calculating channel quality from sub-carriers; determining whether the channel quality is outside a threshold range; selecting a different pilot sub-carrier density for a sub-zone based on the value of the channel quality when the channel quality is outside the threshold range; and setting the sub-zone to the different pilot sub-carrier density. A system for using sub-zones with different pilot sub-carrier densities in OFDMA communications is also described.

摘要： In one or more embodiments, a system and method of managing network channel quality in a wireless communications network includes reporting a channel quality measurement from the particular user to a base station (BS) over an available CQICH, and determining a MCS based, at least in part, upon the channel quality measurement. If a threshold network CQICH capacity is reached during a subsequent data frame such that a CQICH is no longer available, MAC level messages are generated between the BS and the particular user to trigger reporting of signal quality information to the BS by the particular user. After the next CQICH cycle commences and if a CQICH is still unavailable, the signal quality information is continued to be provided via MAC level messages. Otherwise, a CQICH is reallocated for a particular user and channel quality measurement reporting is transitioned back to the CQICH.

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.
