A method and system for scheduling and protecting quiet periods (QP) in a quiet zone (105) for incumbent signal (121) detection in a wireless communications system. The communication system includes a plurality of wireless networks (103, 104), each of the plurality of wireless networks contains at least a master device (101, 401) and a client device (111, 411). In each of the plurality of wireless networks, the master device (101, 401) transmits a beacon (402) that contains a QP schedule (500) and a reservation of a time slot (405) for the client device (411). The client device (111, 411) transmits a request-to-quiet (RTQ) message (412) during the time slot, wherein the RTQ message (412) includes the client device's QP schedule information. The master and client devices within the quiet zone (105) keep quiet during scheduled quiet periods according to the QP schedule information contained in the received beacons and RTQ messages.
A method for scheduling and protecting quiet periods (QP) in a quiet zone (105) in order to detect an incumbent signal (121) in a wireless communications system that includes a plurality of wireless networks (103, 104), each of the plurality of wireless networks containing at least a master device (101, 401) and a client device (111, 411), the method comprising:
A system for detecting an incumbent signal (121) of a wireless communications medium, the system including a plurality of wireless networks (103, 104), the system comprising:
A computer readable storage medium having stored thereon computer executable code, when executed, causing a processor in a master device (101, 401) and a client device (111, 411) to perform a process of scheduling and protecting quiet periods (QP) in a quiet zone (105) in order to detect an incumbent signal (121) in a wireless communications system, the process comprising:
