(English Abstract)
Due to the exponential growth of mobile data and the densification of base stations, it is necessary to newly install various types of transport networks such as fronthaul, mid-haul, and backhaul, to enhance mobile communication networks. However, as the existing wired line based solution was not profitable for mobile communication operators in proportion to data volume growth, there is a need of a new concept and technology that can support flexible deployment of radio access network and enhance the cost efficiency of mobile communication carriers. In this paper, we design a network architecture and a transmission scheme for xHaul link as a unified wireless transport solution for MXN(Mobile xHaul Network) that can improve the installation flexibility and the network mobility with mobile multi-hop relay technology. Then we evaluate the performance of xhaul link in various deployment scenarios through system level simulator. As the results of performance evaluation, we verify that xHaul can provide up to 20Gbps capacity and that MXN can meet the performance requirements of 5G mobile service.
