1.	What are the units of the primary network?(a) Primary node and primary base-station(b) Primary user and primary base-station(c) Primary user and secondary user(d) Primary user and primary nodeI got this question in homework.My question comes from The xG Network Architecture in section Next Generation Wireless Network of Cognitive Radio
Answer» Right choice is (b) Primary user and primary base-station The EXPLANATION is: Primary USERS are licensed users of the spectrum. Primary base-station refers to the FIXED infrastructure network component with a spectrum license. The primary base-station contains LEGACY protocols and xG protocols for supporting communication through xG networks.
