Radio resource efficient cellular broadcast networks

Abstract

Rapid and relentless video traffic growth has brought about network congestion. To alleviate the problem, this paper considers a video content broadcast cellular network via the same frequency channels, enabling to save radio resource compared to the conventional unicast networks. We investigates its efficient resource usage for different user demand by means of stochastic geometric analysis. Consequently, we analytically verify increasing popularity of broadcast contents makes radio resource usage more efficient while decreasing the amount of waste radio resources.
