Claim:
1. A method, comprising: selecting, at a first communication device, an interference covariance calculation technique to be utilized by a second communication device when computing a channel quality indicator (CQI) associated with a communication channel between the first communication device and the second communication device, wherein the interference covariance calculation technique is selected from a set of multiple techniques for calculating interference covariance, and wherein the set of multiple techniques includes i) different techniques corresponding to different sets of one or more transmitters considered as interferers, and ii) an interference covariance calculation technique in which no transmitters in a cluster are considered as interferers; transmitting, with the first communication device, an indication of the selected interference covariance calculation technique to the second communication device; and receiving, at a first communication device, a CQI calculated by the second communication device in accordance with the selected interference covariance calculation technique.
