Apparatus and method for adaptive channel quality feedback in a multicarrier wireless network

Abstract

A subscriber station for use in a wireless network capable of communicating according to a multicarrier protocol determines a total average signal level across N subbands within a channel where each subband comprises a plurality of subcarriers. The subscriber station also determines a first average signal level within a first subband. The subscriber station then transmits a channel quality indicator (CQI) feedback message to the wireless network. The CQI feedback message comprises a first data indicating the total average signal level across the N subbands and a second data indicating the first average signal level within the one subband. The first data may indicate the total average signal level as an absolute value and the second data may indicate the first average signal level relative to the total average signal level using one of two or more unequal quantization levels.
