Abstract
A method, wireless device, and information processing system dynamically update spectrum sensing groups in a wireless communication system. A set of wireless devices (114) currently allocated to a spectrum sensing group is identified. Each wireless device (114, 116, 118) in the set performs spectrum sensing on one or more wireless communication channels. Spectrum sensing performance data (144) is analyzed for each such wireless device (114) in the set. The spectrum sensing performance data (144) indicates wireless communication performance of a wireless device (114) associated with the spectrum sensing performance data with respect to detecting a transmitted signal on the one or more communication channels. Wireless device membership of the set of wireless devices (114, 116, 118) allocated to the spectrum sensing group is dynamically adjusted based on the analysis.
