Abstract: A mobile mux is a radio communication network (RCN) in which base stations (BS's) networked in a tree topology connect a core network (CN) to user equipments (UEs) by installing a backhaul link at a root BS and having non-root BS's wirelessly communicable with the root BS such that all UEs access the CN without a first burden of installing multiple independent backhaul links for all BS's. The frequency resource allocated to the RCN for communicating with the UEs is reused in inter-BS communication, avoiding a second burden of acquiring an additional frequency resource. Avoiding the two burdens enables faster roll-out of communication services. Furthermore, uplink and downlink data traffics between the CN and the UEs are aggregated and received, respectively, at the root BS, allowing a capacity provided by the single backhaul link to be less than a sum of capacities estimated for the independent links.
