Efficient Resource Allocation and Relaying Paradigms for IMT-Advanced Systems

Recently, new network topologies including relays and meshed networks have emerged as a key technology receiving a lot of attention due the increasing need for additional resources such as spectrum and required high data-rates. In this paper, we identify and describe the novel network topologies that will be able to accommodate the foreseen high data rates and resolve the spectrum scarcity paradigm. By efficiently integrating mesh networks and flexible resource sharing, the overall network efficiency of networks can be increased. In addition, direct Terminal-to-Terminal communication with and without the use of relays is highlighted where terminals communicate without the use of base stations as it is done in conventional systems.In this way, efficient radio resource allocation is done. The results show significant gains in terms of users satisfaction and power consumption compared to conventional networks. Finally, open issues and potential challenges are addressed.
