CROSS-LAYER, CROSS-NODE COGNITIVE NETWORK ENHANCED DYNAMIC SPECTRUM ALLOCATION
First Claim
1. A method for dynamically managing Secondary User Node (“
- SUN”
) access to a segment of a wireless spectrum licensed for use by Primary User Nodes (“
PUNs”
), the method comprising;
detecting, by first and second SUNs, physical data transfers by the PUNs at a plurality of first licensed frequencies during a plurality of slot sample times of a first epoch;
generating, by each of the first and second SUNs, a report comprising sensed spectral data indicating(1) during which of the slot sample times each physical data transfer was detected by a respective one of the first and second SUNs, and(2) at which of the first licensed frequencies each physical data transfer occurred;
receiving, by the first SUN, the report broadcasted from the second SUN at a non-licensed frequency during a respective one of a plurality of slot report times following the slot sample times of the first epoch; and
analyzing, by at least the first SUN, 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 the PUNs.

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.

10. A system, comprising:
at least one electronic circuit configured to perform the following operations; detect physical data transfers by a plurality of Primary User Nodes at a plurality of first licensed frequencies during a plurality of slot sample times of a first epoch; generate a first report comprising sensed spectral data indicating (1) during which of the slot sample times each physical data transfer was detected, and (2) at which of the first licensed frequencies each physical data transfer occurred; receive a second report broadcasted from a Secondary User Node (“
SUN”
) at a non-licensed frequency during a respective one of a plurality of slot report times following the slot sample times of the first epoch; andanalyze the sensed spectral data of the first and second reports to determine a time at which a plurality of SUNs should be allowed use of a first licensed frequency without interfering with or only minimally interfering with use thereof by the PUNs. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
