Abstract—The exponential growth of user demands and the limitations of Third Generation of Mobile Communication Sys- tems (3G) have brought researchers to start reflecting on the Fourth Generation (4G). Many prophetic visions have appeared in literature presenting the future generation as the ultimate boundary of the wireless mobile communication without any limit in its potential, but practically not giving any designing rules and thus any definition of it. In this paper we hence propose a new framework — the user centric system — that, through a satellite hierarchical vision, presents the key features of 4G and points out the various level of interdependency among them. This leads to the identification of the designing rules and therefore to a more pragmatic definition of 4G.
