β-PSR: A Partial Spectrum Reuse scheme for two-tier heterogeneous cellular networks

Abstract

In this paper, we consider a Partial Spectrum Reuse (PSR) scheme, namely “β-PSR”, to improve spectrum efficiency of two-tier heterogeneous cellular networks, in which each micro Base Station (BS) occupies a uniform portion β of the whole system spectrum randomly and independently. We analyze the optimal PSR factor β to minimize service outage probability… (More)
