一种适用于大型蜂窝网络的资源分配与协作传输方案

A Resource Allocation and Coordinated Transmission Scheme for Large Cellular Networks

Jing Li, Dongning Guo

摘要:

随着用户设备(UE)和数据需求数量的增加,正在采用更密集的接入点(AP)。资源分配问题已经被广泛研究,其中干扰被视为噪声。多个终端通过相干或非相干的方式进行传输协调,可以显著提高系统的频谱效率,本文重点研究如何选择AP对进行协调,并根据协调结果进行资源分配。通过灵活地优化AP配对、频谱分配、用户关联和功率管理,将网络效用函数最大化。提出了一种基于迭代方案追踪和分式规划的可扩展高效算法。数值结果表明,由于在128个AP和384个UE的网络中的协调传输,网络效用大幅增加。

英文摘要:

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.
