Abstract (en)
[origin: WO2007109169A2] A network of stations uses bandwidth assigned to primary users on a secondary user basis. The stations having a status of needing to send information indicate a need for transmission access by transmitting, simultaneously with transmissions indicating a need for transmission access from other stations of the network, an indication of status to a master station. Each station indicating need for transmission access transmits that indication of status on a respectively different frequency. The master station then grants access to the transmission bandwidth to the requesting stations.
