Abstract

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.
