论文摘要
本文分析了毫米波（MMWAVE）中的混合波束形成（HBF）和多用户多输入多输出（MU-MIMO）（MMWAVE）第五代（5G）蜂窝网络，考虑了带有TCP/IP流量和MAC调度的完整协议堆栈的蜂窝网络。 HBF和MU-MIMO的先前工作已经假设了全缓冲传输并研究了链接级的性能。我们报告了HBF技术，NR中的前频道估计试验方案与MU-MIMO调度的约束之间的非平凡相互作用。我们还报告说，关节多用户面积设计是必须的，因为在将MU-MIMO系统实现为单纯的单用户模拟光束时，无法完全利用MU-MIMO系统。通过解决这些问题，可以通过空间划分多访问（SDMA）在MMWave 5G网络中大大增加吞吐量。
This paper analyzes Hybrid Beamforming (HBF) and Multi-User Multiple-Input Multiple-Output (MU-MIMO) in millimeter wave (mmWave) 5th generation (5G) cellular networks considering the full protocol stack with TCP/IP traffic and MAC scheduling. Prior work on HBF and MU-MIMO has assumed full-buffer transmissions and studied link-level performance. We report non-trivial interactions between the HBF technique, the front-loaded channel estimation pilot scheme in NR, and the constraints of MU-MIMO scheduling. We also report that joint multi-user beamforming design is imperative, in the sense that the MU-MIMO system cannot be fully exploited when implemented as a mere collection of single-user analog beams working in parallel. By addressing these issues, throughput can be dramatically increased in mmWave 5G networks by means of Spatial Division Multiple Access (SDMA).
