Joint rate and SINR coverage analysis for decoupled uplink–downlink biased cell associations in HetNets. IEEE Transactions on Vehicular Technology, 64(1), 147–158. Centralized and distributed solutions for fast muting adaptation in LTE-advanced HetNets. Seven ways that hetnets are a cellular paradigm shift. The derived results are validated by Monte Carlo simulations. The user-clustering is also shown to benefit the coverage and throughput performance relative to the case of HPPP distributed users. The results show that DUDe outperforms the coupled access scheme in terms of coverage and throughput. We derive analytical expressions of the coverage probability and average throughput for DUDe access as well as the conventional coupled access. This work investigates DUDe access for an HCN with user-clustering modeled by the Matern cluster process. However, the HPPP cannot accurately model the uplink interference when the users are clustered in urban hotspots such as shopping malls and sports stadiums. Many authors have evaluated HCN performance while assuming that the network users are distributed according to a homogeneous Poisson point process (HPPP). However, recent investigations have shown that downlink–uplink decoupling (DUDe) can provide network performance gains relative to the conventional coupled access. The performance of heterogeneous cellular networks (HCNs) is typically analyzed with the assumption that the users connect with the same base station in uplink and downlink. ![]()
