Abstract
Configuration information including location and radio capabilities for first and second network nodes (for example, DeNB and RN respectively) are provided to register them to a spectrum access system (SAS). To establish a DeNB-RN backhaul link on a shared radio spectrum the DeNB sends the SAS a request for radio resources and authorization to transmit. The configuration information and/or the request indicates the DeNB and the RN belong to a backhaul system. The DeNB receives a grant for the radio resources and authorization, and broadcasts the authorization to the RN. The RN scans a broadcast channel while its receiver is active and its transmitter is inactive; detects the authorization to transmit, changes its transmitter from inactive to active, and transmits a reply to the DeNB's broadcast. The RN's reply to the DeNB's broadcast is used to establish the backhaul link.
