Abstract

Method, apparatus, and computer program product embodiments are disclosed to provide coexistence values for wireless resource sharing on a fair basis between heterogeneous wireless networks to enable coexistence of secondary networks. An example embodiment of the invention includes a method, comprising the steps of: determining a coexistence value for a wireless network based on parameters associated with the wireless network, including at least one of a number of nodes in the wireless network, a current resource allocation utilization rate of the wireless network, coexistence assistance by the wireless network to assist in operation of other networks, and/or a priority of the wireless network, wherein the coexistence value characterizes eligibility of the wireless network to wireless spectrum resources available to secondary networks; and communicating the determined coexistence value of the wireless network to an associated network controller. The resulting embodiments provide for wireless resource sharing on a fair basis between heterogeneous wireless networks to enable coexistence of secondary networks.
