Current broadband wireless networks are characterized by large cell sizes. Yet, even in advanced networks, users on the cell edge will face relatively low Signal-toInterference-plus-Noise-Ratio (SINR). An attractive solution for this problem is provided by multi-hop technologies. In this paper, we consider the performance of full duplex Amplify-andForward(More)
For multi-hop transmission two basic relaying modes are available: in-band and out-band. The in-band mode is the main solution considered in most state-of-the-art studies and it is the focus of the 3GPP LTE-Advanced specification. This is because the solution requires only one frequency carrier for relay node operation. However, with evolution of cellular(More)
Relays are a cost efficient way to extend or distribute high data rate coverage more evenly in next generation cellular networks. This article introduces a radio resource management solution based on dynamic and flexible resource assignment and cooperative relaying as key technologies to enhance the downlink performance of relay based OFDMA cellular(More)
Decode-and-forward relaying is a promising enhancement to existing radio access networks and is already standardized in 3rd generation partnership project (3GPP) as a part of long term evolution (LTE)-Advanced Release 10. Two inband operation modes of relay nodes are supported, namely type 1 and type 1b. Relay nodes promise to offer considerable gain for(More)
