新无线接入技术NR-MIMO赋形研究

Research on beamforming of new wireless access technology NR-MIMO

5G-NR作为新的无线接入技术,以满足广泛的需求,包括增强的移动带宽、大规模机器式通信、超可靠和低时延通信等。新的无线接入技术能支持高达100 GHz的宽频率范围。但对于6 GHz以上的高频通信,存在着明显的路径损耗和穿透损耗。解决这一问题的方案是部署大型天线阵列以获得高波束赋形增益。因此,研究包括模拟/数字/混合波束形成在内的各种波束赋形的增强型大规模MIMO在内的新型无线电接口的多天线方案是十分必要的。

5G-NR is a new access technology to meet a wide range of needs,including enhanced mobile bandwidth,massive machine-type-communications,ultra-reliable and low-latency communications.The new wireless access technology can support up to 100GHz wide frequency range.However,for high frequency communication above 6GHz,there are obvious path loss and penetration loss.One solution to this problem is to deploy large antenna arrays to achieve high beamforming gain.So it is essential to study multi-antenna scheme for new radio interface including enhanced Massive MIMO with different types of beamforming including analog/digital/hybrid beamforming.
