摘要:

为了满足未来对无线数据服务的巨大业务量的需求,近年来已经进行了对第五代(5G)移动通信系统的研究。预计5G移动通信系统中的频谱和能量效率应该比第四代(4G)移动通信系统中的频谱和能量效率高十倍。因此,重要的是进一步开发多个天线的空间复用的潜力。在过去的二十年中,多输入多输出(MIMO)天线技术被认为是提高无线通信系统容量的关键技术。当在基站中配备大规模天线阵列(也称为大规模MIMO)或部署大量分布式天线(也称为大规模分布式MIMO)时,可以通过使用空间域多址来进一步提高频谱和能量效率。本文综述了大规模MIMO和大规模分布式MIMO系统,包括频谱效率分析、信道状态信息(CSI)获取、无线传输技术和资源分配。

英文摘要:

To meet the future demand for huge traffic volume of wireless data service, the research on the fifth generation (5G) mobile communication systems has been undertaken in recent years. It is expected that the spectral and energy efficiencies in 5G mobile communication systems should be ten-fold higher than the ones in the fourth generation (4G) mobile communication systems. Therefore, it is important to further exploit the potential of spatial multiplexing of multiple antennas. In the last twenty years, multiple-input multiple-output (MIMO) antenna techniques have been considered as the key techniques to increase the capacity of wireless communication systems. When a large-scale antenna array (which is also called massive MIMO) is equipped in a base-station, or a large number of distributed antennas (which is also called large-scale distributed MIMO) are deployed, the spectral and energy efficiencies can be further improved by using spatial domain multiple access. This paper provides an overview of massive MIMO and large-scale distributed MIMO systems, including spectral efficiency analysis, channel state information (CSI) acquisition, wireless transmission technology, and resource allocation.
