论文摘要
随着用户设备数量不断增加和数据需求的增加，正在使用密集的访问点（AP）。资源分配问题已通过被视为噪声的干扰进行了广泛的研究。众所周知，如果多个终端相协调或非连接的传输协调，则可以显着提高整体频谱效率。本文的重点是研究如何选择APS以进行协调并相应地分配资源。通过灵活的方式优化AP削减，频谱分配，用户关联和电源管理来提出优化问题，以最大程度地提高网络实用程序功能。根据迭代方案追求和分数编程提出了可扩展且有效的算法。数值结果表明，由于128个AP和384 UE网络中的协调传输，网络实用程序的大幅增长。
With the increasing number of user equipment (UE) and data demands, denser access points (APs) are being employed. Resource allocation problems have been extensively researched with interference treated as noise. It is well understood that the overall spectral efficiency can be significantly improved if multiple terminals coordinate their transmissions either coherently or non-coherently.The focus of this paper is to study how to select pairs of APs for coordination and allocate resources accordingly. An optimization problem is formulated to maximize the network utility function by optimizing AP paring, spectrum allocation, user association, and power management in a flexible manner. A scalable and efficient algorithm is proposed based on iterative scheme pursuit and fractional programming. Numerical results demonstrate substantial gains in the network utility due to coordinated transmission in a network of 128 APs and 384 UE.
