| 1. A method, comprising:
measuring, by a user equipment, an energy detection value of a received signal on at least one unlicensed channel in an out-of-band
frequency band of a primary system;
sending, by the user equipment, a first measurement report in response to the measured energy detection value of the received
signal on the at least one unlicensed channel being less than a first predetermined threshold to enable use of the at least
one unlicensed channel;
measuring, by the user equipment, a feature detection value of the received signal on the at least one unlicensed channel
in the out-of-band frequency band of the primary system; and
sending, by the user equipment, a second measurement report to enable use of the at least one unlicensed channel, in response
to the measured feature detection value of the received signal on the at least one unlicensed channel being less than a second
predetermined threshold.
