The extremely diverse service requirements is an important challenge for the future generations of wireless communication technologies. As promising solutions, orthogonal frequency division multiplexing (OFDM)-based massive multiple-input multiple-output (MIMO) and mixed numerologies transmission are proposed. This letter investigates the transmission of different users, sharing the same bandwidth while they are associated to different numerologies. A transceiver design which aims to manage the mixed numerology spectrum sharing (SS) transmission is first presented. Then, we analyze the inter-numerology interference (INI) and derive its corresponding theoretical expressions. Based on the derived closed-form expressions, a new INI cancellation scheme is introduced, which efficiently mitigates the INI and enhances the performance of massive MIMO-OFDM uplink systems.

Massive MIMO-OFDM UL混合参数干扰的分析与消除

极其多样化的服务需求是下一代无线通信技术面临的重要挑战。作为有前途的解决方案，提出了基于正交频分复用 (OFDM) 的大规模多输入多输出 (MIMO) 和混合参数传输。这封信调查了不同用户的传输，共享相同的带宽，而他们与不同的数字相关联。首先介绍了旨在管理混合命理学频谱共享 (SS) 传输的收发器设计。然后，我们分析了命理间干扰（INI）并推导出其相应的理论表达式。基于导出的闭式表达式，引入了一种新的 INI 取消方案，
