The Effect of HARQ Procedure on the Performance of LTE System

Firas S. Alsharbaty, Safwan H. Fasola

Open full text 4 citations

Abstract

In this paper, the parameters of the LTE system in DL are investigated. These parameters include the effect of the Hybrid Adaptive Repeat and Request henceforth (HARQ) on the Signal to Noise Ratio (SNR), Block Error Rate (BLER), and throughput. The paper deals with three cases of Channel Quality Indicator (CQI): 3,7 and 15.The results showed that the HARQ procedure can improve the BLER and the throughput when the retransmission between the evolved base station (eNodeB) and a User Equipment (UE) increased
