摘要：
Methods and apparatus for signal and interference energy estimation in a communication system. In an aspect, a method includes setting a threshold value, and comparing a channel estimate to the threshold value to determine an interference estimate (Iest). The method also includes averaging the interference estimate (Iest) to determine average channel interference (Ic), and determining interference energy (I) based on the interference estimate (Iest) and the average channel interference (Ic). In another aspect, an apparatus includes threshold logic configured to set a threshold value and compare a channel estimate to the threshold value to determine an interference estimate (Iest). The apparatus includes averaging logic configured to average the interference estimate (Iest) to determine average channel interference (Ic), and summing logic configured to determine interference energy (I) based on the interference estimate (Iest) and average channel interference (Ic).
