1. A method operable in a radio access network (RAN) having a first base station, at least one second base station, wherein the first base station and the at least one second base station provide overlapping coverage, wherein the first base station communicates with a backhaul network entity of a core network over a first backhaul link, and wherein the at least one second base station communicates with the backhaul network entity over a second backhaul link that is different from the first backhaul link, the method comprising:
determining a first backhaul capacity of the first backhaul link;
determining a second backhaul capacity of the second backhaul link;
establishing, using at least one processing unit, an allocation of carriers of a set of carriers between the first base station and the at least one second based station based at least on a comparison between the determined first backhaul capacity and the determined second backhaul capacity;
causing the first base station to operate on one or more particular carriers of the set of carriers in accordance with the established allocation of the carriers of the set of carriers; and
causing the at least one second base station to operate on one or more other carriers of the set of carriers in accordance with the established allocation of the carriers of the set of carriers.
