“…Beyond 5G encourages rebuilding the conventional design concept to breakthrough various emerging technical limitations [1]. For example, considering various use cases of beyond 5G, an uplink interface would be required from a fronthaul to aggregation backhaul [2]. Even if the fronthaul signal bandwidth remains the same in the MHz-class, the backhaul carrier frequency and signal bandwidth will increase for beyond 5G, and effective data aggregation as well as high frequency migration of carrier frequency and signal bandwidth will be important to communicate with many nodes, terminals, and devices simultaneously.…”

We have proposed a new approach for photonic-assisted arbitrary waveform generation in beyond 5G taking advantage of low frequency technology. The generated signals in low frequency technology can be temporally compressed by a chromatic dispersion toward millimeter wave and terahertz band high frequency region. To the best of our knowledge, our recent proposed approach for beyond GHz-class AWG using the MHz-class low-frequency technology with photonic assistance based on chirped pulse compression is first proposed to remodel it to obtain competitive performances in signal frequency, as well as analog resolution, cost, and power consumption. Various use cases in beyond 5G, a large number of signal from massive edge subsystem should be bundled. This requires a signal processing for aggregation of multi-data from vast multi-user information as well as data compression. The data signal is digitally processed for segmentation and tuning so as to accommodate it in the stretched carrier pulse according to the length of signal. Since signals become sparse in beyond-GHz region after signal compression, the produced temporal free space in a frame could be used for accommodation. Such a produced temporal free space can be used for accommodation of overflowing data and users. This requires an additional signal processing for aggregation of multi-data from vast massive user information as well as data compression. In this work, we propose the photonic data aggregation technique for millimeter wave and terahertz band high frequency migration technology for beyond 5G.
