Claim of US Patent No. 10,405,194

1. A method for providing spectrum sensing capability in a network having at least one primary user and a plurality of secondary users configured to communicate using a shared spectrum, the method comprising:receiving signals from a plurality of sensors positioned at different locations in the network, the locations of the plurality of sensors defining a path;
determining, based on the received signals, values corresponding to received signal strength from the at least one primary user in one or more frequencies of the shared spectrum,
using the values determined based on the received signals from the plurality of sensors to interpolate at least one additional value corresponding to a received signal strength at a location between sensors along the path; and
determining that the at least one primary user is transmitting in the one or more frequencies of the shared spectrum if any of the values determined based on the received signals from the plurality of sensors or the at least one additional value interpolated along the path exceeds a threshold.
