Abstract: Relay stations play an important role in throughput increase data rate and extending coverage for LTE-advanced. One solution to throughput increase data rate and extend the coverage is to use the fixed relays to transmit data between the eNB and UE through multi hop communication. In this study, we propose new study focusing on the optimal deployments different locations and height of antenna relays by analyzing various scenario consisting up to 10 relays using two cooperative relaying strategies AAF and DAF. The data is send over from eNB to UE using multi-hop communication over WINNER channel model in urban microcells of LTE-advanced networks environment. The optimal deployment is determined by evaluating the number of relays and their locations and height of antenna relay at targeted SER or SNR. Simulation results show that relay effectively boost the link performance in comparison with direct connection and also, AAF outperformed DAF. Moreover, the optimal deployment achieved using 2•4 relays with relays located in the close from eNB, also, 4•6 relays when relays located around the cel edge and 8•10 relays when relays located in the cell edge to extend coverage, also, significant SNR gains by increase height antenna relays.
