Future wireless systems will need to offer, for a variety of applications and without limitations to the user location, a high quality access to the Internet similar to what is available today in fixed wired networks. Advanced multi-antenna technologies will most likely be crucial in achieving the target peak spectral efficiency of next generation wireless networks. But, more important than the peak data rate will be the ability of future systems to reliably achieve large data rates in most of the cell coverage area. Furthermore, multi-antenna techniques can only deliver high data rates for signal to noise plus interference ratio (SINR) higher than what is typically available in large areas of the cell. It is therefore necessary to find tools to improve the SINR and multi-hop relaying techniques have been identified as a key approach to achieve this goal. In a relay-based deployment, intermediate relay stations are used to establish a link between the base station and distant mobile users and represent a cost effective solution, versus deploying new base stations, to extend coverage and improve the average spectral efficiency. The goal of the proposed research program is to determine how advanced multi-antenna relaying transmission and cooperation techniques can be beneficial to next generation infrastructure-based cellular networks. More specifically, the research will focus on novel multi-antenna and multi-user MIMO relaying techniques, efficient resource allocation algorithms for multi-antenna relay-based cellular networks, and new interference management techniques based on cooperation between base stations and relays. It is expected that the research project will yield novel results, such as new relaying and cooperation techniques for cellular networks, fundamental limits and tradeoffs analysis for these techniques, practical algorithms to efficiently exploit them, and deployment tools for relay-based networks. The research outcomes should thus be of significant interest to cellular service providers, equipment manufacturers, standardization organizations and the research community. It should therefore contribute to the successful integration of advanced multi-antenna relaying techniques in future high-speed infrastructure-based cellular networks.

未来的无线系统将需要为各种应用程序提供，并且在没有限制的用户位置，对互联网的高质量访问类似于固定有线网络中今天可用的互联网。先进的多Antenna技术很可能对于实现下一代无线网络的目标峰值光谱效率至关重要。但是，比峰值数据速率更重要的是将来系统在大多数单元覆盖区域中可靠地达到较大数据速率的能力。此外，多触角技术只能为噪声和干扰比（SINR）提供高的数据速率（SINR）高于细胞的大面积中通常可用的数据速率（SINR）。因此，有必要找到改善SINR和多跳继电器技术的工具，已被确定为实现此目标的关键方法。在基于继电器的部署中，中间继电器站用于建立基站和遥远的移动用户之间的链接，并代表一个具有成本效益的解决方案，而不是部署新的基站，以扩展覆盖范围并提高平均光谱效率。拟议的研究计划的目的是确定高级多ANTENNA继电器传播和合作技术如何对基于下一代基础架构的蜂窝网络有益。更具体地说，该研究将集中于新型的多用户和多用户MIMO继电器技术，基于多Antenna继电器的蜂窝网络的有效资源分配算法以及基于基站和继电器之间合作的新干扰管理技术。可以预期，研究项目将产生新的结果，例如针对蜂窝网络的新继电器和合作技术，这些技术的基本限制和权衡分析，可有效利用它们的实用算法以及基于中继网络的部署工具。因此，研究结果应该引起蜂窝服务提供商，设备制造商，标准化组织和研究界的重大兴趣。因此，它应该有助于在未来的基于高速基础架构的蜂窝网络中成功整合高级多ANTENNA继电器技术。
