Abstract

En 中文

Small cell is one of the key technologies in modern wireless communications, extending cell coverage and providing capacity increment. However, challenges still exist in realizing and optimizing the small cell networks. In this letter, we propose a distributed iterative threshold control scheme with minimal increase in hardware complexity to improve the energy efficiency of sleep mode control by reducing the number of unbeneficial mode transitions. We also show that the proposed scheme provides improved system adaptability to network traffic time-variation compared with conventional sleep mode control schemes.
