- Abstract
- To meet the 5G requirements for large-capacity transmission in the RAN architecture, 3GPP and O-RAN Alliance discussed new open fronthaul interface specifications. Functional split option 7-2x of O-RAN is widely used by many vendors for their fronthaul. Recently, since the modem of the base station access platform is being developed as software that operates in real time, the fronthaul interface function is also implemented as software. This paper introduces a structure that implements the High-PHY function in software, which was designed in hardware in the O-DU platform, which serves as a 5G base station. In addition, the software implementation of the fronthaul interface on this platform and the performance of the compression method of the fronthaul link were analyzed.
