1. A method, comprising:
- receiving a pilot signal over a first channel at a receiver;
receiving a rate indicator signal over a second channel at the receiver;
determining a rate indicator signal-to-noise ratio (SNR) of the rate indicator signal based on a plurality of rate indicator channel symbols that are accumulated at the receiver; and
estimating a pilot SNR of the pilot signal based at least in part on the rate indicator SNR of the rate indicator signal.

Abstract
A method and apparatus for providing uplink signal-to-noise ratio (SNR) estimation in a wireless communication system. A first signal is received over a first channel and a second signal is received over a second channel, where the second signal is received at a higher signal power level than said first signal. A signal-to-noise ratio (SNR) of the second signal is measured, and the SNR of the first signal is determined based at least in part upon the measured SNR of the second signal.
