    • Provided is a method for transmitting and receiving multimedia broadcast multicast service (MBMS) data in a packet based cellular system. The method for transmitting multimedia broadcast multicast service (MBMS) to a plurality of mobile stations in a packet based cellular system, includes the steps of: a) transmitting scheduling information of transmission data, b) hybrid automatic repeat request (HARQ) information, and a service group identifier (ID) for MBMS to the mobile stations through a MBMS dedicated control channel; b) transmitting information about a dedicated feedback channel of a mobile station and unique scrambling codes different by cells and mobile stations to the mobile stations; c) transmitting a MBMS data packet to the mobile station; d) transmitting radio resource information of data retransmitted using a downlink control signal to the mobile stations if negative acknowledgment (NACK) is received from at least one of the mobile stations; and e) transmitting the retransmitted data to the mobile stations.
    • 提供了一种在基于分组的蜂窝系统中发送和接收多媒体广播多播服务(MBMS)数据的方法。 在基于分组的蜂窝系统中向多个移动站发送多媒体广播组播服务(MBMS)的方法包括以下步骤:a)发送传输数据的调度信息,b)混合自动重传请求(HARQ)信息,以及 通过MBMS专用控制信道向移动台发送用于MBMS的业务组标识符(ID); b)向移动台发送关于移动台的专用反馈信道的信息和由小区和移动台不同的唯一扰码; c)向所述移动台发送MBMS数据分组; d)如果从所述移动站中的至少一个接收到否定确认(NACK),则向所述移动站发送使用下行链路控制信号重发的数据的无线资源信息; 以及e)将重传的数据发送到移动站。
