摘　　要：多媒体广播多播业务(MBMS)是3GPPR6版本中定义的一种典型的广播、多播业务。随着技术的演进,在LTE系统中提出了增强的MBMS,即eMBMS业务。针对eMBMS业务,提出了一种有效的技术解决方案。该方案可看作下行发射分集、基于DoA的波束赋形与HARQ技术的结合。Multimedia broadcast,/multicast service（MBMS） is one typical service defined in 3GPP Release 6. In Long Term Evolution（LTE）, evolved（ e） -MBMS has also been defined to enhance the MBMS transmission. In this paper, an efficient scheme applicable to single-cell point-to-multipoint e-MBMS transmission is proposed. It can be seemed as the combinations of downlink transmit diversity,Direction of Arrival（DoA） based beam-forming and hybrid-ARQ（HARQ） retransmission. Simulation results show the significant performance improvement compared with pure downlink transmit diversity scheme.
