Evolved node-B, shared spectrum controller and method for communication in shared spectrum
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.

receive, from the public shared spectrum repository, a spectrum unavailability message that indicates an unavailability of the shared spectrum for the secondary usage; and
send, to the mobile network shared spectrum controller, an indicator of the unavailability of the shared spectrum,
wherein the shared spectrum is reserved for primary usage by one or more incumbent devices, and

send, to a public shared spectrum repository excluded from the mobile network domain, a secondary usage verification message that indicates the secondary usage of the shared spectrum and obfuscates an identity of the base station; and
receive, from the public shared spectrum repository, an indicator of whether the secondary usage is in compliance with a shared spectrum policy.
10. The non-transitory computer-readable memory medium according to claim 9 , wherein:
the mobile network shared spectrum repository is configured to operate with the public shared spectrum repository as part of a Licensed Shared Access (LSA) repository, and

11. The non-transitory computer-readable memory medium according to claim 10 , wherein the identity of the base station is obfuscated in the secondary usage verification message to enable a confidentiality of mobile network configuration information within the mobile network domain.
12. The non-transitory computer-readable memory medium according to claim 9 , wherein the software instructions are further configured to cause the mobile network shared spectrum repository to:
receive, from the shared spectrum controller, mobile network configuration information for the mobile network that is based at least partly on operation of the base station in the mobile network,
send, to the public shared spectrum repository, a public portion of the mobile network configuration information, and
restrict sending of a confidential portion of the mobile network configuration information to the public shared spectrum repository.
13. The non-transitory computer-readable memory medium according to claim 12 , wherein the restriction of the sending of the confidential portion of the mobile network configuration information is to enable an obfuscation of the confidential portion from the public shared spectrum repository.
14. The non-transitory computer-readable memory medium according to claim 9 , wherein the software instructions are configured to cause the mobile network shared spectrum repository to:
receive, from the public shared spectrum repository, a spectrum unavailability message that indicates an unavailability of the shared spectrum for the secondary usage; and
send, to the mobile network shared spectrum controller, an indicator of the unavailability of the shared spectrum,
wherein the shared spectrum is reserved for primary usage by one or more incumbent devices, and
wherein the unavailability of the shared spectrum is based on a reclaiming, by the one or more incumbent devices, of the shared spectrum for the primary usage.
15. The non-transitory computer-readable memory medium according to claim 9 , wherein:
the mobile network includes a Third Generation Partnership Project (3GPP) network, and
the mobile network shared spectrum repository operates as part of a Network Management Layer Service (NMLS) of the 3GPP network.
