论文摘要
比例博览会（PF）是一种调度技术，可在最大化吞吐量和确保对用户的公平性之间保持平衡。第三代伙伴关系项目（3GPP）引入了双连通性（DC）技术，以提高异质网络中的移动性鲁棒性和系统能力。在本文中，我们证明了DC在改善系统中比例公平性方面的实用性。我们建议针对DC的低复杂性集中PF调度方案，并表明它的表现优于标准PF调度方案。由于用户在系统中最大化比例公平性的双重关联问题是NP-HARD，因此我们为DC提出了三个启发式用户协会方案。我们证明，DC与拟议的PF方案一起，在单个连接性上为PF实用程序带来了显着的收益，并且几乎在异质网络中几乎接近最佳PF方案。
Proportional Fair (PF) is a scheduling technique to maintain a balance between maximizing throughput and ensuring fairness to users. Dual Connectivity (DC) technique was introduced by the 3rd Generation Partnership Project (3GPP) to improve the mobility robustness and system capacity in heterogeneous networks. In this paper, we demonstrate the utility of DC in improving proportional fairness in the system. We propose a low complexity centralized PF scheduling scheme for DC and show that it outperforms the standard PF scheduling scheme. Since the problem of dual association of users for maximizing proportional fairness in the system is NP-hard, we propose three heuristic user association schemes for DC. We demonstrate that DC, along with the proposed PF scheme, gives remarkable gains on PF utility over single connectivity and performs almost close to the optimal PF scheme in heterogeneous networks.
