1. An apparatus of a user equipment (UE), the apparatus comprising:processing circuitry, the processing circuitry configured to:
encode a registration request for registering within a device hierarchy system;
decode configuration information from a base station (BS) within the device hierarchy system, the configuration information including spectrum assignment information of spectrum that is available to the BS, the configuration information received in response to the registration request and the available spectrum being assigned to the BS prior to encoding the registration request;
determine an allowed level of interference with at least a second device within the device hierarchy system; and
decode spectrum reassignment information, the spectrum reassignment information re-assigning the available spectrum based on the allowed level of interference; and
memory configured to store the spectrum assignment information and the spectrum reassignment information.
