Abstract  Abstract

PROBLEM TO BE SOLVED: To reduce communication overheads and to eliminate packaging complexity in a hybrid ARQ (Automatic Retransmission Request) method for packet data transmission.

SOLUTION: Previously transmitted packets are combined with retransmitted packets. Each packet is segmented into a plurality of protocol data units PDUs and sequence numbers for identification are respectively imparted to the respective PDUs. The sequence number is transmitted in a control channel which is independent of the data channel for transmitting the PDUs.
