Abstract  Abstract

A subscriber station for use in a wireless network capable of communicating according to a multicarrier protocol. The subscriber station determines a total average signal level across N subbands where each of 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 field indicating the total average signal level and a second data field indicating the first average signal level. The first data field may indicate the total average signal level as an absolute value and the second data field may indicate the first average signal level relative to the total average signal level.
