Downlink Coverage Probability in Multi - Tier Rician Fading HetNets
Heterogeneous cellular networks (HetNets), consisting of macrocells overlaid with small cells, have become an integral part of existing cellular wireless networks to satisfy an ever increasing demand for mobile broadband applications and services. In this paper, the coverage probability in a downlink HetNet, comprising of multi-tier MIMO Base Stations (BSs) serving multiple users, assuming Rici...
متن کاملCoverage and Rate Analysis for Location-Aware Cross-Tier Cooperation in Two-Tier HetNets
Heterogeneous networks (HetNets) are regarded as a promising approach to handle the deluge of mobile data traffic. With the co-channel deployment of small cells, the coverage and capacity of the network will be improved. However, the conventional maximum-received-power (MRP) user association scheme and cross-tier interference issue significantly diminish the performance gain provided by small c...
متن کاملAnalytical Study on Multi-Tier 5G Heterogeneous Small Cell Networks: Coverage Performance and Energy Efficiency
In this paper, we investigate the coverage performance and energy efficiency of multi-tier heterogeneous cellular networks (HetNets) which are composed of macrocells and different types of small cells, i.e., picocells and femtocells. By virtue of stochastic geometry tools, we model the multi-tier HetNets based on a Poisson point process (PPP) and analyze the Signal to Interference Ratio (SIR) v...
متن کاملFeedback Design for Multi-Antenna K-tier Heterogeneous Downlink Cellular Networks
We characterize the ergodic spectral efficiency of a non-cooperative and a cooperative type of Ktier heterogeneous networks with limited feedback. In the non-cooperative case, a multi-antenna base station (BS) serves a single-antenna user using maximum-ratio transmission based on limited feedback. In the cooperative case, a BS coordination set is formed by using dynamic clustering across the ti...
متن کاملEnergy-Efficiency Study for Two-tier Heterogeneous Networks (HetNet) Under Coverage Performance Constraints
Recently, heterogeneous networks (HetNet) have been widely studied as an effective approach to provide high network capacity and coverage, which jointly utilizes the technologies of cognitive radio and cooperative communications. However, the dense and random deployment of small-cells (e.g., micro, pico and femtocells) raises important questions about the energy consumption for HetNets. In this...
