Abstract
The design of fronthaul link has become a challenging task in the 5th Generation Mobile Network (5G). In this paper, in order to reduce 5G fronthaul delay and jitter, a multi-thread scheduling receiving method based on interrupt and polling mode is introduced. Considering diverse application scenarios in 5G, we present a new scalable and flexible 5G fronthaul architecture to manage high data traffic flows efficiently. In the end, a hardware system is built to verify the method and fronthaul architecture. Experiments show that delay and reliability can meet the requirements of 5G fronthaul design. Besides, the designed architecture can be used in other distributed high-speed transmission systems to increase their flexibility and efficiency.
