Macrocell Protection Interference Alignment in Two‐Tier Downlink Heterogeneous Networks
Mobile Information Systems, Volume 2017, Issue 1, 2017., 2017 Conventional interference alignment (IA) has been developed to mitigate interference problems for the coexistence of picocells and macrocells. This paper proposes a macrocell protection interference alignment (MCP‐IA) in two‐tier MIMO downlink heterogeneous networks.

Distributed Association Method Assisted by Cell for Efficiency Enhancement of Wireless Networks
Mobile Information Systems, Volume 2017, Issue 1, 2017., 2017 In this paper, we propose a distributed cell association scheme called cell‐guided association method (CGAM) to improve the efficiency of a wireless network. In CGAM, MSs attempt to associate with their best cells. However, unlike the conventional methods, cells do not passively accept the association requests of MSs. Instead, a cell determines whether

Playing Radio Resource Management Games in Dense Wireless 5G Networks
Mobile Information Systems, Volume 2016, Issue 1, 2016., 2016 This paper considers the problem of an efficient and flexible tool for interference mitigation in ultradense heterogeneous cellular 5G networks. Several game‐theory based approaches are studied, focusing on noncooperative games, where each base station in the end tries to maximize its payoff.

Improving the Spectral Efficiency in Dense Heterogeneous Networks Using D2D-Assisted eICIC
, 2018 Heterogeneous networks (HetNets) that consist of macro base stations (MBSs) and small base stations (SBSs) are a key architectural drive for achieving the high spectral efficiency (SE) in 5G and beyond.

Mathematical Problems in Engineering, Volume 2016, Issue 1, 2016., 2016 In cellular heterogeneous networks (HetNets), offloading users to small cell base stations (SBSs) leads to a degradation in signal to interference plus noise ratio (SINR) and results in high outage probabilities for offloaded users. In this paper, we propose a novel framework to solve the cell association problem with the intention of improving user ...
