| 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。同时，仿真结
果也表明，该方案相对于单独的发射分集来说能带来显著的性能增益。 |

| Abstract: |
| 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 defi
ned to enhance the MBMS transmission. In this paper, an efficient schem
e applicable to single-cell point-to-multipoint e-MBM
S transmission is proposed. It can be seemed as the combinations of downlink tra
nsmit diversity,Direction of Arrival(DoA) based beam-forming and hybrid-ARQ(HA
RQ) retransmission. Simulation results show the significant performance improvem
ent compared with pure downlink transmit diversity scheme. |
