We analyze the power-saving operation in Third-Generation Partnership Project (3GPP) Long-Term Evolution Advanced (LTE Advanced) wireless networks. Typically, it is an exhausting and complicated job to numerically analyze the performance of power-saving operations since it is necessary to carefully consider every possible probability, make probability-generating functions, and differentiate these functions. Instead, we develop a totally new approach toward simple but accurate derivations. For this purpose, we divide the time period for the steady-state power-saving operation into several independent parts. Then, we analyze the power-saving operation in each part and thereafter combine the results into an aggregate result. The new approach enables us to avoid sophisticated steps while we reach an accurate analytical model. The equations are validated through comparison with simulation results.
