一种新颖的针对单小区点对多点e-MBMS业务传输技术
An Efficient Scheme for Single-cell Point-to-multipoint e-MBMS Transmission*
摘要
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 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-form-ing and hybrid-ARQ(HARQ)retransmission. Simulation results show the significant performance improvement compared with pure downlink transmit diversity scheme.关键词
