In this letter, the authors formulate the energy‐efficient user association and cell sleeping optimisation problem which applies to the multi‐tier ultradense network scenarios as a complex 0–1 integer programming and propose an alternating iterative method to solve the problem via two low‐complexity sub‐problems. The simulation results show that the proposed strategy can steadily reduce overall energy consumption compared with the existing strategies.
