摘要

随着飞蜂窝的引入,蜂窝网络正从传统的集中式架构转向分布式架构,在这种架构下,每个网络小区都应该做出自己的无线电资源管理决策,同时提供小区间的干扰缓解。然而,实现这种分布式蜂窝网络架构并不是一项简单的任务。本文首先引入了一种简单的自组织规则,在此规则下,分布式蜂窝网络能够收敛为一种有效的资源分配模式,然后提出了一种考虑现实资源分配约束的新型资源分配模型,最后通过系统级仿真对所提出的自组织规则和资源分配模型的性能进行了评估。

Minimising cell transmit power: towards self-organized resource allocation in OFDMA femtocells
With the introduction of femtocells, cellular networks are moving from the conventional centralised architecture to a distributed one, where each network cell should make its own radio resource management decisions, while providing inter-cell interference mitigation. However, realising this distributed cellular network architecture is not a trivial task. In this paper, we first introduce a simple self-organisation rule under which a distributed cellular network is able to converge into an efficient resource allocation pattern, then propose a novel resource allocation model taking realistic resource allocation constraints into account, and finally evaluate the performance of the proposed self-organisation rule and resource allocation model using system-level simulations.
