| Abstract: | In this paper, we present a study of the impact of physical layer interference on the MAC layer operations in LTE (Long Term Evolution), in particular, on HARQ (Hybrid ARQ) acknowledgment mechanism.
Our work consists of a campaign of measurements and tests that verify the impact and the utility of HARQ technology on the throughput, the transmission time and the number of packets versus the error rate.
This work would pave the way for further research in this technology in order to improve the interaction between the most important layers, physical and MAC. Many results of the simulation using Opnet Modeler Wireless are presented . The results obtained are very satisfactory and confirm that the mobility factor plays an important role in traffic exchanged between the nodes causing the packet loss due to collisions, obstacles and other factors caused by node mobility. To address this problem, HARQ protocol occurs in the retransmission of lost packets in an efficient manner that does not disrupt the response time or traffic between nodes.
