摘要： Methods and systems for adjusting a forward link (FL) signal to interference and noise ratio (SINR) are provided. In an example, a FL SINR is estimated for each user in a plurality of users, on at least one of each user's respective data rate control (DRC) message or each user's respective prior FL SINR value. The respective estimated FL SINR for a user in the plurality of users is increased, if, based on a reverse link acknowledge message, the user has decoded a packet before all symbols in the packet have been transmitted. Remaining control channel power is determined. The estimated FL SINR for all users in the plurality of users is increased if remaining control channel power is less than a low threshold. The estimated FL SINR for all users in the plurality of users is increased if the remaining control channel power is greater than a high threshold.

摘要： A system and method for Interference Cancellation (IC). One aspect relates to iterative interference cancellation with iterative finger delay adaptation. The interference cancellation method comprises receiving multi-paths of a signal; and performing iterative interference cancellation to remove multi-path interference, wherein the performing iterative IC comprises estimating a Signal-to-Interference-plus-Noise Ratio (SINR) at each of a plurality of pre-determined rake receiver finger delays, and performing successive Channel Estimation (CE) and IC on rake receiver fingers according to their estimated SINRs, and wherein the CE of a next finger does not start until interference of a previous finger is removed from a sample buffer. The method may further comprise improving estimated rake receiver finger delay, and each iteration decreases the amount of interference observed by each finger.

摘要： Systems and methods are described herein for managing beacon signaling in a wireless communication system. A method described herein includes identifying a neighboring macrocell and a time division multiplexing (TDM) channel offset of the neighboring macrocell, the channel offset corresponding to at least one of a signaling channel or an overhead channel; selecting a local channel offset that differs from the channel offset of the neighboring macrocell; and generating a transmission schedule such that first transmissions are omitted for at least a portion of transmission intervals of the neighboring macrocell; wherein the transmission intervals of the neighboring macrocell are identified according to the channel offset of the neighboring macrocell and wherein the first transmissions include at least one of pilot transmissions, medium access control (MAC) transmissions or traffic transmissions.
