Relaying is one of the features being suggested for the 4 G LTE advanced systems. The goal of LTE relaying is to enhance both coverage and capacity and achieve higher spectral efficiency. Relaying is a potential solution to improve the coverage and capacity in LTE-Networks especially at the cell edges which suffer from inter-cell interference. Moreover, using of relay is very attractive because of its potential low cost and simple deployment. This paper shows that deploying of relays can significantly improve both system capacity and coverage. In term of signal to interference noise ratio (SINR), spectral efficiency and transmission path loss the proposed scheme achieves excellent improvement over the conventional scheme without using relay. The fixed relay half-duplex decode – and – forward (DF) has been used as it is the most promising type.
