A power-saving scheduling algorithm for mixed multicast and unicast traffic in MBSFN

In this paper, A power-saving scheduling algorithm (PSA) for mixed multicast and unicast traffic is proposed in multicast and broadcast single frequency network (MBSFN). This algorithm is designed on the purpose of reducing the terminal´s energy consumption and improving system capacity. By MBSFN area scheduling scheme the throughput of multicast users is increased. And the users´ energy consumption is reduced by decreasing the transition times between sleeping and active status in the use of discontinuous reception (DRX) mechanism which is applied for terminal´s battery power saving in LTE. The simulation results show that the proposed strategy gains an improvement both in system throughput and the terminal´s energy efficiency.
