一种多媒体广播多播业务数据传输方法、网络设备和终端设备
摘要：
本发明公开了一种多媒体广播多播业务MBMS数据传输方法，预先确定MBMS数据子帧的打孔信息，该方法包括：A.演进通用陆地无线接入网基站eNB根据所确定的打孔信息对当前MBMS数据子帧打孔，将下行物理层控制信令映射到打孔位置上并将MBMS数据映射到未被打孔位置，发送给用户设备UE；B.UE根据当前MBMS数据子帧对应的打孔信息，从接收到的当前MBMS数据子帧中获取下行物理层控制信令，并根据自身需要获取MBMS数据。本发明还提供了一种发送MBMS数据的网络设备和接收MBMS数据的终端设备。中本发明能够提高通信系统的吞吐速率并增强调度的灵活程度。
摘要（英）：

The invention discloses a data transmission method of the multimedia broadcasting multi-broadcasting service (MBMS), predefining the punching information of a MBMS data subframe. The method includes two steps. Firstly, an evolutionary universal terrestrial radio access network base station (eNB) punches the present MBMS data subframe according to the defined punching information, maps the control signals of the downlink physical layer on the punched position and maps the MBMS data on the unpunched position, and then the MBMS data subframe is sent to the user equipment (UE); secondly, according to the punching information corresponding to the present MBMS data subframe, the user equipment (UE) acquires the control signals of the downlink physical layer from the received present MBMS data subframe, and according to the requirement, acquires the MBMS data. The present invention also provides a network device sending the MBMS data subframe and a terminal device receiving the MBMS data subframe. The present invention can increase the throughput rate of a communication system and enhance the flexibility of dispatching.
