Traffic engineering functionalities are described in a heterogeneous network that includes an anchor base station serving a cellular macro cell and booster base stations serving mmWave enabled small cells. The described functionalities are designed to cope with dynamic changes in the heterogeneous environment such as loss of a backhaul link between the anchor base station and the booster base station, loss of a link between a terminal and one of the base stations, and loss of beam forming in a mmWave link between the terminal and the booster base station.
