Method and System for Dynamic Adaptation and Communicating Differences in Frequency - Time Dependent Systems

Abstract

Aspects of a method and system for dynamic adaptation and communicating differences in frequency-time dependent systems may include generating a time difference weighting factor and a frequency difference weighting factor, based on at least channel estimates. A time-frequency difference may be computed by forming a weighted sum comprising a time difference and a frequency difference, where forming the weighted sum uses at least the time difference weighting factor and the frequency weighting factor. A channel quality indicator (CQI) feedback message may be generated, comprising the time-frequency difference. The time difference weighting factor and/or the frequency difference weighting factor may be generated adaptively at a base station or a mobile terminal. The time difference and/or the frequency difference may be generated from estimated Signal-to-Noise-Ratios (SNRs) associated with the channel estimates. The SNRs may be based on at least the output of an MMSE receiver.
