Energy-efficient Scheduling for the Real-time Multicast and Unicast Traffic in MBSFN

Abstract

In order to minimize the user terminal energy consumption under the circumstance of ensuring the delay performance of real-time multicast and unicast traffic, this paper proposes a novel energy-efficient scheduling algorithm. According to the demand relation between the user and the traffic in the MBSFN area, this paper establishes a system model of the user terminal energy consumption. It analyzes the upper bound value and lower bound value of the user terminal energy consumption, and realizes the integrated scheduling of the traffic set by using the idea of centralized burst transmission, so as to obtain the minimum value of the user terminal energy consumption. The simulation results show that the proposed algorithm greatly reduces the user terminal energy consumption under the circumstance of ensuring the traffic delay performance.
