Following the rapid increase in penetration rate of broadband services the Third Generation Partnership Project 3GPP is currently standardizing the Evolved-Multimedia Broadcast Multicast Service E-MBMS framework of Long Term Evolution LTE the successor of Universal Mobile Telecommunications System UMTS . MBMS constitutes a point-to-multipoint downlink bearer service that was designed to significantly decrease the required radio and wired link resources. However several obstacles regarding the high-power requirements should be overcome for the realization of MBMS. Techniques such as Macrodiversity Combining and Rate Splitting could be utilized to reduce the power requirement of delivering multicast traffic to MBMS users. In this paper we analytically present several power saving techniques and analyze their performance in terms of power consumption. We provide simulation results that reveal the amount of power that is saved and reinforce the need for the usage of such techniques. Copyright 2009 Antonios Alexiou et al.
