    • 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.
    • 提供了用于调整前向链路(FL)信号与干扰和噪声比(SINR)的方法和系统。 在一个示例中,在每个用户的相应数据速率控制(DRC)消息或每个用户相应的先前FL SINR值中的至少一个上,针对多个用户中的每个用户估计FL SINR。 如果基于反向链路确认消息,则用户已经在分组中的所有符号已经被发送之前解码了分组,则增加了用于多个用户中的用户的相应估计的FL SINR。 确定剩余控制通道功率。 如果剩余控制信道功率小于低阈值,则在多个用户中的所有用户的估计的FL SINR增加。 如果剩余的控制信道功率大于高阈值,则对于多个用户中的所有用户的估计的FL SINR增加。

    • 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.
