摘要

大规模多输入多输出（MIMO）技术大大提高了 5G 网络的性能，其潜力有望在即将推出的 6G 标准中得到进一步拓展。发射器的大型天线阵列与每个用户的多个天线相结合，可实现多用户多层 MIMO 数据传输。与传统的三矢量平面阵列配置相比，本文研究了三维场景中圆柱形阵列排列的潜在优势。事实上，圆柱阵列可以更均匀地覆盖小区，不会产生波束宽度，还能缓解扇区边缘问题。为此，我们评估了使用配备单极化和双极化天线元件的圆柱阵列的多用户和多层预编码与组合策略的有效性，这些策略是在最新的符合 3GPP 标准的 5G 3D 信道模型下进行的，并考虑了不完善的信道估计所造成的损害。针对室外视距（LOS）、室外非视距和室内用户，在和速率、频谱效率和中断方面提供了结果并与平面阵列进行了比较。这些研究突出了在现实三维场景中使用圆柱阵列的优势，即使不同扇区的平面阵列作为单个阵列协调运行时也是如此。这使得圆柱阵列成为下一代 6G 网络的理想解决方案。

Multi-Layer Multi-User MIMO With Cylindrical Arrays Under 3GPP 3D Channel Model for B5G/6G Networks

Massive MIMO technology has significantly enhanced the performance of 5G networks, and its potential is poised for further expansion in the upcoming 6G standard. Large antenna arrays at the transmitter, combined with multiple antennas at each user can enable multi-user multi-layer MIMO data transmission. In this paper, we study the potential benefits of a cylindrical array arrangement in a 3D scenario, compared to the conventional trisector planar array configuration. In fact, cylindrical arrays allow for more uniform coverage of the cell, don’t suffer from beam broadening, and can mitigate the sector-edge problem. For this purpose, we assess the effectiveness of multi-user and multi-layer precoding and combining strategies using cylindrical arrays outfitted with both single and dual-polarized antenna elements, under the most recent 3GPP-compliant 3D channel model for 5G, and by taking into account impairments due to an imperfect channel estimation. Results and comparisons with planar arrays in terms of sum-rate, spectral efficiency and outage are provided for outdoor Line-of-Sight (LOS), outdoor Non-LOS, and indoor users. They highlight the benefits of using cylindrical arrays in realistic 3D scenarios, even when the planar arrays of the different sectors are coordinated to operate as a single array. This makes them an interesting solution for next-generation 6G networks.

期刊介绍： IEEE Access® is a multidisciplinary, open access (OA), applications-oriented, all-electronic archival journal that continuously presents the results of original research or development across all of IEEE''s fields of interest. IEEE Access will publish articles that are of high interest to readers, original, technically correct, and clearly presented. Supported by author publication charges (APC), its hallmarks are a rapid peer review and publication process with open access to all readers. Unlike IEEE''s traditional Transactions or Journals, reviews are "binary", in that reviewers will either Accept or Reject an article in the form it is submitted in order to achieve rapid turnaround. Especially encouraged are submissions on: Multidisciplinary topics, or applications-oriented articles and negative results that do not fit within the scope of IEEE''s traditional journals. Practical articles discussing new experiments or measurement techniques, interesting solutions to engineering. Development of new or improved fabrication or manufacturing techniques. Reviews or survey articles of new or evolving fields oriented to assist others in understanding the new area.
