Institute of Electrical and Electronics Engineers (IEEE)Calabuig Gaspar AbstractThis paper analyzes the challenges and opportunities that the upcoming definition of the future Fifth-Generation (5G) mobile networks brings to the mobile broadband and broadcast industries to form a single converged network. It reviews the state-of-the-art on mobile and broadcast technologies and the current trends for convergence between both industries. This paper describes the requirements and functionalities that the future 5G must address in order to make an efficient and flexible cellularbroadcasting convergence. Both industries would benefit from this convergence by exploiting synergies and enabling an optimum use of spectrum based on coordinated spectrum sharing.

The evolution of LTE towards 5G has started and different research projects and institutions are in the process of verifying new technology components through simulations. Coordination between groups is strongly recommended and, in this sense, a common definition of test cases and simulation models is needed. The scope of this paper is to present a realistic channel model for urban macrocell scenarios. This model is map-based and takes into account the layout of buildings situated in the area under study. A detailed description of the model is given together with a comparison with other widely used channel models. The benchmark includes a measurement campaign in which the proposed model is shown to be much closer to the actual behavior of a cellular system. Particular attention is given to the outdoor component of the model, since it is here where the proposed approach is showing main difference with other previous models.
