AI 中文摘要
本文提出了一种用于协作蜂窝和无小区大规模 MIMO 系统的叠加传输策略。通过将用户分为近程和远程，基站为每个近程用户发送一个额外的数据符号，叠加在分布式接入点的信号上。近程用户接收器采用连续干扰消除来解码两个符号。该策略在保持小区边缘公平性的同时实现了最高的峰值频谱效率，在系统容量方面优于所有现有网络配置。
英文摘要
This paper proposes a superimposed transmission strategy for cooperative cellular and cell-free massive MIMO systems. By classifying users into near and far, the base station transmits an additional data symbol for each near user, superimposed on the signals from distributed access points. Successive interference cancellation is employed at near-user receivers to decode both symbols. The proposed strategy achieves the highest peak spectral efficiency while maintaining fairness at the cell edge, thereby outperforming all the existing network configurations in system capacity.
