Abstract:
1. A method, with a wireless communication controller, for dynamically updating spectrum sensing groups in a wireless communication system, the method comprising: identifying a set of wireless devices currently allocated to a spectrum sensing group, wherein each wireless device in the set performs spectrum sensing on one or more wireless communication channels; analyzing, with each such wireless device in the set, spectrum sensing performance data that indicates wireless communication performance of a wireless device associated with the spectrum sensing performance data with respect to detecting a transmitted signal on the one or more communication channels, wherein the analyzing further comprises observing a time series of the spectrum sensing performance data for each wireless device in the set for a given time interval and constructing an estimate of a probability of detection over time for each wireless device in the set based on observing the time series associated therewith; and dynamically adjusting wireless device membership of the set of wireless devices allocated to the spectrum sensing group based on the analyzing.
