The bandwidth for around both 30 and 70 GHz is up to 1 GHz. 10 users per cell are distributed uniformly and all users are indoors with 3 km per hour velocity. Full buffer and/or burst traffic model is assumed. • Dense urban The dense urban heterogeneous deployment scenario focuses on macro cells with micro cells and high user densities and traffic loads in city centres and dense urban areas. The key characteristics of this deployment scenario are high traffic loads, An Overview of 5G Requirements 19 outdoor and outdoor-to-indoor coverage.

This is done using an indicative scaling in three steps as “high”, “medium” and “low”. In the enhanced mobile broadband scenario, the user experienced data rate, area traffic capacity, peak data rate, mobility, energy efficiency and spectrum efficiency all have high importance, but mobility and the user experienced data rate would not have equal importance simultaneously in all use cases.
