Energy efficiency of uplink users is critical for evaluating the energy consumption of heterogeneous cellular networks (HCNs) with heavy loading. The energy efficiency of user equipments (UEs) in HCNs depends heavily on power control scheme as well as maximum power constraint. This paper investigate the energy efficiency of uplink UEs in HCNs taking into account the flexible power control policy along...
In this paper, the average uplink transmission rate and outage probability of UEs are analyzed in heterogeneous small cell networks. The impact of the power control coefficient on both system performances is evaluated taking into account the intercell interference in a stochastic geometry network. Furthermore, we propose an energy-efficient uplink power control scheme, which adjusts the power control...
In this paper, the uplink outage probability and energy efficiency of user terminals are investigated for heterogeneous networks (HetNets). In order to characterize the performance of users in small cells, the probability distribution function (PDF) of the distance between a user terminal and the access point (AP) in the typical small cell is derived in closed-form expressions. On this basis, the...
It is of great importance for service providers to evaluate the impact of inter-cell co-channel interference on the outage probability in cellular networks. In this paper, the probability density function (PDF) of interference factors limited by power control scheme is derived. Moreover, a series-form outage probability affected by the interference from Poisson-Voronoi tessellation (PVT) cellular...
It is of great importance for service providers to evaluate the impact of inter-cell co-channel interference on the achievable data rate in cellular networks. In this paper, the cumulative distribution function (CDF) of the inter-cell interference factor is derived. On this basis, closed-form expression of the maximum achievable rate subject to the interference from finite planar cells is analyzed...
