Method and apparatus for providing channel quality feedback in an orthogonal frequency division mulitiplexing communication system

In an OFDM communication system, a mobile station provides a radio access network (RAN) a channel quality metric second order statistic, in one embodiment a signal to noise plus interference power ratio (SINR) second order statistic and in particular an SINR standard deviation and/or variance, along with a mean channel quality metric, that is, a mean SINR. By providing both a mean channel quality metric and a channel quality metric second order statistic, the communication system permits the RAN to create a more accurate fading profile of an associated air interface, and in particular a downlink of the air interface, thereby facilitating an improved scheduling decision over the prior art and assuring that a packet has a higher probability to go through a downlink channel without too many retransmissions.
