## Abstract

Embodiments of an Evolved Node-B (eNB), shared spectrum controller and methods for communication in shared spectrum are generally described herein. A mobile network shared spectrum controller may operate as part of a domain of a mobile network. A public shared spectrum controller may operate externally to the mobile network domain. The mobile network shared spectrum controller and the public shared spectrum controller may operate cooperatively to perform operations of a shared spectrum controller, such as management of secondary usage of shared spectrum by a group of eNBs. The mobile network shared spectrum controller may obfuscate at least a portion of network configuration information from the public shared spectrum controller to enable maintenance of confidential information within the mobile network domain.
