Abstract
Systems (100) and methods (700) for dynamically managing Secondary User Node (“SUN”) access to a segment of a wireless spectrum licensed for use by Primary User Nodes (“PUNs”). The methods comprise: detecting physical data transfers by PUNs (110-122) at first licensed frequencies (f1, f2, f3, f4) during slot sample times of a first epoch (t1-t15); generating a report comprising sensed spectral data indicating (a) during which of the slot sample times each physical data transfer was detected by a respective SUN (102-108) and (b) at which of the first licensed frequencies each physical data transfer occurred; receiving a report broadcasted from a remote SUN at a non-licensed frequency during a respective slot report times (t16-t19) of the first epoch; and analyzing the sensed spectral data of the reports to determine a time for using a first licensed frequency without interfering with or only minimally interfering with use thereof by PUNs.
