Enhanced radio resource management introducing smart direct link concepts
Matthias Siebert · 2003
This paper investigates an enhanced radio resource management scheme in centralised controlled radio cells. It thereby introduces a new scheduling approach for resource grants with a special focus on the appliance of direct terminal-to-terminal operation as offered by various upcoming wireless broadband communication systems. In order to obtain a more efficient use of available resources, solutions have to be found, how resources in self-organising radio systems can be used in parallel by applying direct link communication between mobile terminals. The decision about multiple assignments of the same resources is performed by a central instance considering the interference situation within the cell. The combination of the direct link communication and the sophisticated scheduling under the control of a central instance is referred to as 'Smart Direct Link (SDiL) appliance. Performance simulations for this novel concept indicate large gains when applied to specific scenarios.
