Abstract: A method for managing uplink communication in wireless communication network is provided. The method includes selecting one or more Mobile Stations (MSs) from a plurality of MSs based on a first signal parameter corresponding to each MS of the one or more MSs, one or more second signal parameters corresponding to each MS of the one or more MSs, and one or more threshold parameters. The first signal parameter is associated with a Base Station (BS) serving a MS. Further, the one or more second signal parameters are associated with one or more BSs neighboring to the MS. The one or more threshold parameters are associated with a communication parameter. Thereafter, the method includes modifying uplink Modulation and Coding Scheme (MCS) level of the one or more MSs.

Abstract: A method and apparatus of selecting a number of uplink sounding sub-carriers are disclosed. One method includes estimating an uplink channel of between a base station and a subscriber. A time domain channel response is determined from the estimated uplink channel. A sub-carrier distribution of uplink sounding sub-carriers is selected based on characteristics of the time domain channel response, wherein the distribution defines a spacing of pilot sub-carriers within the uplink sounding symbol. The subscriber transmits uplink sounding symbols having the selected sub-carrier distribution.
