The general requirements for a 4G system will mainly be derived from the types of service a user will require in the future. An information transport platform must provide high-speed, large volume, good quality, global coverage and flexibility to roam. To ensure this effective global coverage, we propose to derive the benefits of mobile ad-hoc networks research and couple it with the reconfiguration technology. Towards this end we propose a flat type IP architecture that enables a rapid deployment of micro- and pico-type of base stations and incorporates the open radio access network (RAN) within the all-IP paradigm. Within that architecture, wireless nodes or access points have to be interconnected using a long-haul backbone network. The proposed architecture exploits the idea of coupled physical layer adaptation and scheduling leading to intelligent algorithm design for such future wireless networks. The integrated link adaptation (ILA) strategies proposed span both the AMC sub-layer and physical layer. This paper outlines some of the components of the aforementioned flat architecture, rationale and the methodology behind the coupling of the ad-hoc networks and the underlying resource management issues for network adaptation in bursty packet communications.
