摘要：A kind of transmission of data and ARQ agreements in multicast groups, such asthe system of GSM, GPRS or UMTS mobile communication using being described. (for Tfrom a transmitter to multiple receivers (R1-RM), the data block (PDU) is can be byidentifier (for example, sequence number) for the data block (PDU) of data transmission.The receiver sends whether state instruction (R1-RM) (T) data block (PDU) is correctlyreceived to transmitter. Transmitter T adapts to execute to retransmit has transmissionstate (PDU) of the transmissive window comprising data block according to its markaccording to state instruction. In the method, (T) synchronous with transmitter executesat least one first described receiver (invaded zone resistivity, wherein the selectionsynchronization in a series of identification transmission data block (PDU). The mark ofthe transmission state selection of transmitter T (deletion) stops sending the mark ofstatus indicative datum block (PDU) corresponding to selection from above-mentioned
transmission window and the first receiver (invaded zone resistivity). In addition,
transmitter and computer program realize the description of this method. For example,the transmitter, which can be RNC, obtains efficient and reliable point to multi-pointwireless current source road by 3GPP in RLC and MAC-HSPDA consensusstandardizations.
