【摘要】：在超密集网络场景中,小区密度持续增加使得干扰关系更加复杂,重叠虚拟小区结构使得资源分配深度耦合,导致虚拟小区选择成为影响系统性能的因素之一。为此,针对虚拟小区边权重设计,采用联合资源分配前置化思想,提出一种综合了干扰公平功率分配、MU-MIMO配对及协作传输诸增益因素的权重方案。针对虚拟小区成簇,基于提出的权重设计准则,通过最大权重成对小区成簇算法实现虚拟小区可重叠成簇。仿真结果表明,提出的虚拟小区生成算法可在低计算复杂度的前提下保证系统性能的改善。
[Abstract]:In the super-dense network scenario, the continuous increase of cell density makes the interference relationship more complex, and the overlapping virtual cell structure makes the resource allocation deeply coupled, leading to the selection of virtual cell as one of the factors affecting the performance of the system. Aiming at the edge weight design of virtual cell, a new weighting scheme which combines the gain factors of interference fair power allocation and cooperative transmission is proposed by using the idea of joint resource allocation prepositioning. For virtual cell clustering, based on the proposed weight design criterion, the maximum weight pair cell clustering algorithm is used to realize virtual cell overlapping clustering. Simulation results show that the proposed virtual cell generation algorithm can guarantee the improvement of system performance with low computational complexity.
