Apparatus and method for feedback of subcarrier quality estimation in an OFDM/OFDMA system

摘要

A method for subcarrier quality estimation in a wireless network is disclosed. The method comprises analyzing characteristics of at least some of the subcarriers of a first signal, creating feedback data based on the analyzed characteristics, wherein the quantity of the feedback data is less than the quantity of all of a plurality of measured signal-to-interference and noise power ratio (SINR) values of each subcarrier of the first signal, and transmitting the feedback data.
