Prediction-Based Handover Schemes for Relay-Enhanced LTE-A Systems

Relay Nodes (RN) have been suggested to be placed near the edge of a cellular network in order to improve link qualities of cell edge User Equipments (UEs). Compared to conventional homogeneous networks, system performance for the relay-enhanced network can be significantly degraded if handovers between the RNs and evolved Node Base-station (eNB) are not correctly and immediately determined by the eNB. Therefore, the UEs may suffer from worse channel conditions which can result in increased energy consumption of entire network.
