摘要：
In this paper, the uplink energy efficiency and uplink outage probability for two-tier cellular access networks (TTCANs) are investigated. To model of the uplink energy efficiency and uplink outage probability in TTCANs, a closed-form expression of signal-to-interference ratio (SIR) is derived by considering the on/off states of femtocell access points (APs). Moreover, a second order kernel function is firstly used to solve the analytical interference model with femtocell APs turning on in TTCANs. Simulation results show that femtocell user’s intensity has great impact on the uplink energy efficiency and uplink outage probability in a TTCAN. These results provide some guidelines for developing new energy saving schemes in practical TTCANs deployment.
