I would like to ask this question from Next Generation Wireless Network topic in chapter Next Generation Wireless Network of Cognitive Radio

Answer 1

Correct option is (d) Choose multiple access techniques

Easiest explanation: MAC layer in cognitive radio should manage the level of accessibility provided for resources of the radio. MAC layer should be aware of channel occupancy and surrounding spectrum environment to quickly handle changes in the environment and to mitigate loss produced due to mobility. MAC layer should have the capability to change design configuration.
