论文摘要
本文研究了工业互联网（IoT）毫米波通信的双层非正交叠加的传输。从本质上讲，覆盖仪是一个普遍存在的多播信号，该信号设计用于将所有设备提供覆盖范围的所有设备，即通用消息，即关键控制数据包。卧式是一个复合信号，由私人单播消息组成。由于安全性的影响，所有设备都可以解码多播信息至关重要。为了确保这一要求，我们共同优化了混合预言器，模拟组合者，功率分配和公平性。具体而言，我们在两个覆盖信号和执行补充的每设备约束以保证多播公平性之间结合了电源分裂约束。根据频谱效率，多播公平性和位错误率评估性能，从而证实了我们提出的方案的可行性。
This paper investigates dual-layer non-orthogonally superimposed transmissions for industrial internet of things (IoT) millimeter-wave communications. Essentially, the overlayer is a ubiquitous multicast signal devised to serve all the devices in coverage with a common message, i.e., critical control packet. The underlayer is a composite signal that consists of private unicast messages. Due to safety implications, it is critical that all devices can decode the multicast information. To ensure this requirement, we jointly optimize the hybrid precoder, analog combiners, power allocation, and fairness. Specifically, we incorporate a power splitting constraint between the two overlaid signals and enforce supplementary per-device constraints to guarantee multicast fairness. Performance is evaluated in terms of the spectral efficiency, multicast fairness, and bit error rate, thus corroborating the feasibility of our proposed scheme.
