Abstract
A hybrid ARQ method for packet data transmission in a mobile communication system wherein previously transmitted packets are combined with retransmitted packets. The packets are segmented into a plurality of protocol data units (PDUs), and each PDU is assigned a sequence number for identification purposes. The sequence number is transmitted on a control channel which is separate from the data channel for transmitting the PDUs.
