Aspects of the present disclosure relate to methods and apparatus for assigning channels to networks in a group based on network coverage overlap and network weights. An example method generally includes determining whether channels are available for allocation at each network represented by a node in a network overlap graph, wherein each node in the graph is associated with an assigned channel in a shared spectrum, and for each network in the graph for which channels are available for allocation, identifying channels that are available for allocation to the network, and assigning at least one of the available channels to the network based, at least in part, on a weighting associated with the network.
