In this paper, we propose a new wireless transport network, which is named as Mobile Xhaul Network(MXN), that is enable to bring cost efficiency of fronthaul, midhaul and backhaul and to make easy installation of 5G Radio Access Network(RAN). For this purpose, we design XDU discovery and xhaul link setup mechanism with MXN architecture and operational procedure. Especially, in this paper, we propose various types of beam discovery mechanisms for mmWave based radio access on XDU and evaluate proposed schemes. The Simulation result shows that threshold based scheme and information based scheme have less than about 50% beam discovery latency compared to full search scheme.
