Abstract
Femtocell technique has become a radical approach to improve network capacity and coverage. To efficiently reduce interference between femto BS and other BSs, low duty operation mode (LDM) is deemed as a good method to mitigate the interference. In this work, we develop a mechanism that incorporates the power saving mechanism in both femto BS (LDM mode) and MSs (sleep mode). To correspond to the current IEEE 802.16m system architecture, we build a practical system model and analyze the performance of the proposed modification. The simulation shows that with simple sleep-cycle operation, our mechanism can achieve both a high sleep ratio and an acceptable low delay without generating more control overhead than original system requirement. With the above characteristics, our mechanism provides a solid basis to create a green communication system.
