Mitigating Performance Degradation in LTE Advance using Relaying Node

Long Term Evolution-Advanced (LTE-Advanced) is the 3rdGeneration Partnership Project (3GPP) candidate technology which is expected to enhance cell edge capacity, system throughput as well as reduce the user and control plane latencies. Generally in the wireless networks, the cell edge users are experiencing a low signal-to-noise-interference ratio (SINR), causes the low user throughput which leads to overall bad system performance. Similarly, it also causes the small cell coverage and capacity at the cell edge. Moreover,the 3GPP LTE-Advanced is required to provide peak data rates in order to support the high data services and applications. In order to solve this problem, the relaying technique has been proposed. Relays are expected to improve the system capacity and coverage as the low SINR users will hand over to the relay node and utilize the system resources efficiently. To meet these requirements, different LTE-Advanced technologies have been studied in which includes relay
