Mbms data transmission and receiving in packet based on mobile communication system

A method for transmitting and receiving broadcast and multicast service data in a packet based mobile communication system is provided to enhance error correction efficiency by applying an HARQ(Hybrid Automatic Repeat Request) scheme while transmitting MBMS data to plural terminals. MBMS data is transmitted to plural terminals in multiple cells. A service group ID for the MBMS(Multimedia Broadcast and Multicast Service) and shared feedback control information for respective cells are transmitted to the terminals through a control channel(301). The shared feedback control information for respective cells is commonly used for the terminals in the same cell. The MBMS data packet is transmitted to the terminal(302). When a response is received through the shared feedback channel from one of the terminals, wireless resource information of the data to be retransmitted through a downlink control channel is transmitted to the terminals(304). The retransmission data is transmitted to the terminals(305).
