摘要: Techniques for utilizing a capacity-based effective signal-to-noise ratio (SNR) to improve wireless communication are described herein. In an embodiment, mobile terminal can determine the SNR from forward link channel using pilot/data symbols. The convey base station. order minimize transmission overhead, quantize prior transmitting it another station reverse link. utilize facilitate scheduling transmissions terminal, power control commands and determining supporting data rate example. Suitable SNRs include constrained, unconstrained, average, and/or approximated SNRs. addition, various filters, such as averaging filter, be utilized further process SNR.
