Various embodiments are described to enable multiple, independent communication networks to share in an autonomous and dynamic manner unlicensed wireless resources. Generally, this involves determining that a first network node (122) is using at least a portion of a wireless resource to provide network service to at least one remote unit (102). A second network node (123), under the control of a different network operator than the first node and desiring to use the wireless resource, sends the first network node, a request to relinquish use of at least a portion of the wireless resource. The second network node sends this request wirelessly, perhaps using the wireless resource itself. If the first network node grants the request, the second node may then begin using at least a portion of the relinquished resource to provide network service.
