Abstract:
Techniques for addressing high interference observed by a receiver in a wireless communication system are disclosed. The receiver may observe different interference power levels across a transmission symbol received at the receiver. The receiver may determine a signal power level of the transmission symbol. In an aspect, the receiver determines a first interference level for a first portion of the transmission symbol and determines a second interference power for a second portion of the transmission symbol. In an aspect, the receiver applies different weights to different portions of the transmission symbol to account for fluctuation of interference power across the transmission symbol. The weights for each portion may be based on a ratio of the signal power level and the respective interference power level. The receiver may scale the first and second portions of the transmission symbol based on the first and second weights.
