Abstract

Wireless communication systems and methods related to spectrum use negotiations are provided. A first wireless communication device transmits, to a controlling entity of a spectrum, a spectrum use request for a local operator to use the spectrum for a time period. The first wireless communication device receives, from the controlling entity, a spectrum use grant indicating that the local operator is promoted from a first priority to a second priority for accessing the spectrum during the time period. The first wireless communication device communicates with a second wireless communication device in the spectrum during the time period based on the second priority, where at least the first wireless communication device or the second wireless communication device is associated with the local operator.
