Abstract:
1. A method comprising: generating local availability information that indicates first spectrum units within a spectrum that are available to a first node; receiving other-node availability information that indicates second spectrum units within the spectrum that are available to a second node with which the first node seeks to communicate; identifying, based on the local availability information and the other-node availability information, available spectrum units from the first spectrum units and the second spectrum units that can be used to communicate between the first node and the second node; and selecting a channel using one or more of the available spectrum units for handling communication between the first node and the second node, wherein the channel is selected based on expected shares of the one or more available spectrum units for at least the first node or the second node, the expected shares being determined by taking maximums of residual airtimes and fair shares of airtimes for the one or more of the available spectrum units, wherein the spectrum is used by privileged entities and the first node is a non-privileged entity having subordinate rights to the spectrum compared to the privileged entities, and wherein at least the selecting is performed by a communication device.
