Abstract

Embodiments of an Evolved Node-B (eNB), Local Controller (LC) device, and methods for allocation of shared spectrum for secondary usage are generally described herein. In some cases, primary usage of the shared spectrum may be prioritized over the secondary usage of the shared spectrum. The eNB may receive, from the LC device, a spectrum availability message that indicates an availability of the shared spectrum for the secondary usage. The eNB may transmit, to the LC device, spectrum sensing information that is based at least partly on one or more signal strength measurements for UEs connected to the eNB. The eNB may further transmit, to the LC device, a spectrum engagement message that indicates an intention of the eNB to use at least a portion of the shared spectrum for communication with the UEs.
