Answer 1

The correct answer is (a) Expected interference at primary user

To explain I would say: The expected amount of interference on the primary user due to an xG user is the interference of interest in xG architecture. Interference at the primary transmitter can be controlled through the radiated power, the out-of-band emissions, and the location at the transmitters.
