MBMS DATA TRANSMISSION AND RECEIVING IN PACKET BASED ON CELLULAR SYSTEM |
摘要 |
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.
