METHOD AND APPARATUS FOR PROVIDING UPLINK SIGNAL-TO-NOISE RATIO (SNR) ESTIMATION IN WIRELESS COMMUNICATION SYSTEM

摘要

FIELD: radio engineering, communication.;SUBSTANCE: invention relates to communication systems and can be used to estimate uplink signal-to-noise ratio (SNR) in a wireless communication system. The method of estimating SNR in a wireless communication system includes receiving a control signal over a first channel in a receiver. A transmission rate indicator signal is received over a second channel in the receiver, wherein the power level of the transmission rate indicator signal is greater than that of the control signal. In the processor, the SNR of the transmission rate indicator signal is determined based on a plurality of transmission rate indicator channel symbols that are accumulated in the receiver, and the SNR of the control signal is estimated based at least in part on the product of the SNR of the second channel and the inverse of the ratio of the second channel to the control signal for a specific data transmission rate over a data communication channel.;EFFECT: high reliability of estimating SNR.;35 cl, 9 dwg
