Abstract :
We investigate an analytically tractable model of energy efficiency for dynamic Time Division Duplex (TDD) cellular networks. Based on a stochastic geometry, we first derive the expressions for the coverage probability of a homogeneous network which consists of a single class of base stations (BSs). Simulation results confirm the accuracy of our expressions. Then we use these conclusions for modeling the average energy efficiency of a typical user equipment (UE) or a BS in the dynamic TDD cellular network. In addition, we discuss the impact of fractional power control on the average energy efficiency. Our findings show that the increase of the fractional power control factor allows a decrease of the average rate and the average energy efficiency of the whole network.
