Outage probability of the tagged macro user. Outage probability of the tagged macro user (or any randomly chosen macro user) under perfect and imperfect sensing scenarios for the CR femto-BSs. The system parameters are set as P F = 22 dBm, P P = 42 dBm, α = 4, p RB = 0.8, p tx = 0.7, μ = 0.2, μ p = 1, K = 1, \( {\lambda}_F^{\hbox{'}}=700 \) , \( {\lambda}_M^{\hbox{'}}=12 \) , and λ M = 50.
