Hybrid RRM Architecture for Future Wireless Networks

Abstract

The concept of ubiquitous and scalable system is applied in the IST WINNER II [1] project to deliver optimum performance for different deployment scenarios from local area to wide area wireless networks. The integration of cellular and local area networks in a unique radio system will provide a great advantage to final users and operators, compared with the nowadays situation with many disconnected systems and users equipped with different subscriptions, radio interfaces and terminals. To this issue, the IST project WINNER II has defined three system modes suited to local, metropolitan and wide area respectively. The aim of this paper is twofold: first, it presents an architectural solution for scalable and hybrid radio resource management to efficiently integrate the different WINNER modes; second, it proposes a hybrid handover mechanism to exploit the availability of the different modes in the WINNER system.

“…We also stress that centralized algorithms will continue to occupy an important position since they provide the benchmark performance for assessing the effectiveness of distributed algorithms. In addition, hybrid centralized and distributed schemes may have a place in future network deployment as proposed in [19]. We now briefly discuss some of the basic tools employed for designing RRM solutions.…”
