本文评估了使用大规模MIMO波束形成作为提高无线网络能量性能的工具的技术潜力。通过系统级仿真，评估了几何结构、用户比特率、所需站点间距离、区域功率、不连续传输比和传输过程中的相对功率消耗，并将结果与传统的三分区部署进行了比较。仿真结果表明，大规模MIMO波束形成可以显著降低网络区域的功耗，特别是在网络规划过程中考虑到这一收益的情况下，与没有大规模MIMO天线系统的参考三分区部署相比，可以实现站点间距离更大的部署。例如，我们注意到，如果我们将网络设计为10 Mbps的小区边缘用户吞吐量目标，则通过大规模MIMO波束形成实现的5dB额外链路预算可以用于降低50%的网络区域功率消耗。
This paper evaluates the technology potential of using massive MIMO beamforming as a tool to enhance energy performance of radio networks. The geometry, user bit rate, required inter site distance, area power, discontinuous transmission ratio, and relative power consumption during transmission is evaluated by means of system level simulations and the results are compared with a traditional three-sectorized deployment. The simulation results indicate that massive MIMO beamforming can reduce network area power consumption significantly; especially if the gains are taken into account in the network planning process by enabling a deployment with larger inter site distance compared to the reference three-sectorized deployment without massive MIMO antenna systems. As an example we note that 5 dB additional link budget achieved by the massive MIMO beamforming can be used to reduce network area power consumption with 50% if we design the network for a 10 Mbps cell edge user throughput target.
