1.	Which among the following is true about xG users in an unlicensed spectrum band?(a) xG user has equal rights to access the spectrum(b) xG user vacate the spectrum band upon arrival of the primary user(c) xG user vacate the spectrum band upon arrival of another xG user(d) xG users compete for the position of primary userI had been asked this question in class test.My doubt stems from The xG Network Architecture topic in division Next Generation Wireless Network of Cognitive Radio
Answer» The CORRECT option is (a) xG user has equal rights to access the spectrum To explain I would SAY: In the UNLICENSED spectrum band, each user has the same right to access the spectrum bands. The xG users PRESENT in one particular area MAY use the same portion of the spectrum band for communication.
