Abstract

To satisfy the requirement of increasing mobile traffic, heterogeneous networks (HetNets) will be deployed for the fifth generation (5G) mobile communications systems. Since the deployment of base stations (BSs) in HetNets is generally dense and random, stochastic geometry has increasingly been used to analyze the performance of HetNets. Most of the existing work is based on Poisson point processes (PPPs), which lead to some closed-form expressions for local delay and energy efficiency. Considering the geographical distribution of BSs, PPP may not be accurate enough. In contrast, a Poisson cluster process (PCP) proves more realistic for the deployment of BSs. In this paper, by using the discontinuous transmission (DTX) mode, the local delay and energy efficiency based on PCP have been analyzed. It is found that the local delay is larger and the energy efficiency is lower under PCP because of the strong intra-cluster interference. However, the local delay under PCP becomes similar to that under PPP if the radii of clusters are sufficiently large.
