Energy Saving via Efficient Allocation of Paging Frames

Abstract

We propose an alternative design for paging in 5G networks, and investigate its potential for increasing the energy efficiency of base stations. The proposed design allocates the paging frames in certain radio frames, aiming at providing longer sleep opportunities to the base stations. This allows more hardware components to be deactivated and reduces the number of transitions between active and sleep mode, leading to lower energy consumption. The resulting energy saving is evaluated and compared with that of the reference paging scheme. Numerical results demonstrate that noteworthy energy savings are achieved for certain parameter configurations.
