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
