Integration of cooperation on WINNER II System Concept

This report presents the layered protocol stack of the WINNER wireless system, and describes the system functions associated with the IP Convergence Layer (IPCL), the Radio Resource Control (RRC). The document provides a consolidated description of the system functions associated to the IPCL and RRC layers of the WINNER system concept. An innovative and hybrid and scalable approach is proposed for the radio resource management architecture It includes a baseline of pure distributed RRM architecture, where many functions reside in the BS (handover, admission control, load control, etc.), and the option of a centralized RRM server, that supports advanced functions that need a central node to coordinate sets of BSs (inter-cell frequency reuse, inter-cell load balancing, etc ). The centralized RRM is proposed to obtain optimal performance in situations of medium-high load in the network and also when advanced functionalities are needed. The combination of WINNER stand-alone location information with the measurecments based on satellite navigation systems (GPS, Galileo) has been analyzed for the location service support. The results have been validated by simulations. The last part of this document includes the simulation results of the algorithms for intramode, intermode and inter-RAN handovers, using a multimode/multi-RAN terminal. As advanced technique, simulation results on the performance of fuzzy logic based inter-system handover are presented.
