项目摘要
One option for mobile operators to improve coverage and provide high-data-rate services in a cost-effective way is the emerging femtocell network, where low-power femtocell access points (FAPs), each being able to provide high-data-rate wireless connections to users within a short range, are overlaid on macro/micro cellular networks. Indoor deployments of femtocells can solve the problem of weak macrocell signal inside a building and offload a large amount of traffic from macrocells, leading to a promising solution for ubiquitous indoor/outdoor coverage with a single radio-access technology, such as the orthogonal frequency division multiple access (OFDMA) that has been considered in the downlink by major candidate technologies for next generation wireless networks. OFDMA combined with femtocells is widely expected to deliver massive improvements of coverage and capacity for wireless networks. Inter-cell interference management is among the most urgent challenges that operators must face before femtocells can be widely deployed. As plug-and-play devices, most FAPs will be deployed by end users and could be moved or switched on/off at any time. The number and locations of active FAPs are by no means known to operators. Therefore, inter-cell interference in femtocells cannot be managed using conventional network planning methods. An FAP has to be able to integrate itself into the cellular network with least interference caused. Most existing work on interference avoidance in femtocell deployments is for wideband code division multiple access (WCDMA) networks, while little work has been done for OFDMA-based femtocells, where interference avoidance can be implemented from a perspective of temporal and spectral reuse of OFDMA radio resources across different cells. This project aims to develop solutions for inter-cell interference avoidance through OFDMA downlink resource allocation in a network that has femtocells overlaid on macrocells. We will focus our work on the following two tasks: a) the development of a low-complexity interference-avoidance solution based on partial temporal and spectral reuse of OFDMA radio resources between femtocells, and b) the development of a dynamic time-frequency resource allocation algorithm for the OFDMA downlink to provide inter-cell interference avoidance and achieve a frequency reuse factor of 1 across macro and femto cells of the network. These cutting-edge topics cover some of the key aspects of future wireless networks and may lay the foundation to attain ubiquitous indoor/outdoor coverage.
移动运营商以具有成本效益的方式改善覆盖范围并提供高数据速率服务的一种选择是新兴的Femtocell网络,其中低功耗的fomtocell访问点(FAPS),每个网络都能够在短范围内向用户提供高数据速率的无线连接,在宏观/微型细胞网络上覆盖了较短的范围。 Femtocells的室内部署可以解决建筑物内部较弱的Macrocell信号的问题,并从宏观细胞中卸载大量流量,从而通过单个放射性频率技术(例如Orthoconal频率分区(OFDMA)的固定型固定型,从而使无线电频率的竞争方式在下一代中均可通过一系列候选人进行统治,从而为无处不在的室内/室外提供了有希望的解决方案。 OFDMA与Femtocells相结合,被普遍期望可提供无线网络覆盖范围和容量的大规模改善。核层间干扰管理是操作员在广泛部署femtocells之前必须面临的最紧急挑战之一。作为插件设备,大多数FAP将由最终用户部署,并且可以随时移动或关闭。活动FAP的数量和位置绝不是操作员所知道的。因此,无法使用常规网络计划方法对femtocells中的细胞间干扰进行管理。 FAP必须能够将自己集成到蜂窝网络中,并导致最小的干扰。大多数现有关于避免干扰部门部署中的干扰工作的工作都是用于宽带代码部门多访问(WCDMA)网络,而基于OFDMA的Femtocells的工作很少,可以从跨不同单元的OFDMA无线电资源的时间和光谱重复使用的角度实施干扰避免。该项目旨在通过OFDMA下行链路资源分配在具有较大的型号的网络中通过OFDMA下行链路资源分配来开发解决方案,以覆盖型号。我们将把工作重点放在以下两项任务上:a)基于部分时间和光谱重复使用femtocells之间的ofdma无线电资源的低复杂性干扰避免解决方案,b)开发动态的时间频率资源分配算法,以提供频率和频率为频率的频率和频率的频率为频率和频率的频率1的频率。这些尖端的主题涵盖了未来无线网络的一些关键方面,并可能为获得无处不在的室内/室外覆盖范围奠定基础。
