Abstract—Long Term Evolution (LTE) is a step towards the 4th generation (4G) of radio technologies designed to increase the capacity and speed of mobile wireless access. In Release 8, LTE was standardized by 3GPP as the successor of the Universal Mobile Telecommunication System (UMTS).Before full commercial deployment of LTE, downlink SNR to CQI mapping for different multiple antenna techniques can be of enormous significance for the operators. Such vital RF parameters should be tuned before full-fledged commercial launch. In LTE, Adaptive Modulation and Coding (AMC) has to ensure a BLER value smaller than 10%. The SNR-to-CQI mapping is required to achieve this goal. In this paper, Downlink SNR to CQI Mapping for LTE has been performed for Flat Rayleigh channel in fast fading in different transmission modes considering HARQ.

Index Terms—BLER, CQI, LTE, Multi transmission, SNR.
