Abstract- Cross-layer design is becoming a popular design
methodology for the IP-based next-generation wireless systems,
and cross-layer signalling is a key enabler of such a methodology.
Several methods are emerging to achieve this signalling in
layered protocol stacks. Through these methods, the refined
wireless systems are expected to gain significant performance
improvement and/or obtain extended functionality that is very
hard if not impossible to obtain from a single layer signalling.
This paper begins with a survey of representative cross-layer
signalling methods. Based on the analysis, the paper proposes an
efficient, flexible and comprehensive scheme defined here as
Cross-LAyer Signalling Shortcuts (CLASS), and then a set of
