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 a hybrid scheme of DL link adaptation in a network having mobile stations (MSs) in communication with a base station (BS). The system may include a mode decision module associated with the base station. The mode decision module may include one or more processors configured to select a first mode configuration for use during transmission of a first communication from the base station. The BS may receive first feedback information associated with the first communication, where the first feedback information includes a first mode recommendation and first channel information. Based on the first feedback information, the BS may generate a BS-derived mode configuration based on the first channel information and compare the first mode recommendation and the BS-derived mode configuration. Based on the comparison, the BS may determine a second mode configuration to use to configure a second communication.

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.
