论文摘要
在下一代通信中，切片可以选择和分配网络资源，以适应非常不同的垂直驱动用例和应用程序的要求。这项工作通过提出在物理层切片的新颖概念来解决快速的实时资源切片。为了实现这样一个概念，将正交变换设计为将正交频部多路复用（OFDM）符号分为分级速率和延迟的切片。与原始帧的任何载体或时间分割相比，优势是所提出的技术不需要传输时的通道信息。同样，框架的开销也可以改善，并且解码时间保持简单。
In next generation communications, slicing enables the selection and allocation of network resources to suit the requirements of very different vertical-driven use cases and applications. This work addresses fast real-time resource slicing by proposing the novel concept of slicing at the physical layer. To implement such a concept an orthonormal transform is devised that splits the Orthogonal Frequency Division Multiplex (OFDM) symbol into slices with ranked rate and latency. The advantage over any carrier or time segmentation of the original frame is that the proposed technique does not require channel information at transmission. Also, the frame overhead improves, and the decoding time is kept simple.
