Method and apparatus for received transmission symbol processing

摘要

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.

主权项

1. A method for wireless communication, comprising:
receiving a transmission symbol at a receiver; determining a signal power level of the transmission symbol; determining a first interference power level for a first portion of the transmission symbol received during a first time period; determining a second interference power level for a second portion of the transmission symbol received during a second time period that is non-overlapping with the first time period; determining a first weight, for the first portion of the transmission symbol, based on a ratio of the signal power level and the first interference power level; determining a second weight, for the second portion of the transmission symbol, based on a ratio of the signal power level and the second interference power level, the second weight being different than the first weight; and scaling the first and second portions of the transmission symbol based on the first and second weights, respectively, wherein the determining the first interference power level includes:
measuring a first received power of the first portion of the transmission symbol;measuring a second received power of the second portion of the transmission symbol; anddetermining the first interference power level based on the measured first received power of the first portion and the measured second received power of the second portion of the transmission symbol.
