METHOD FOR RETRANSMISSION IN MOBILE COMMUNICATON SYSTEM

摘要

A method of retransmission in a mobile communication system is provided to enhance transmission efficiency by interlocking ARQ(Automatic Retransmission Request) with HARQ(Hybrid Automatic Retransmission Request) in the mobile communication system. A method of retransmission in a mobile communication system includes the steps of: shifting to a second layer waiting status if first layer receiving failure information according to the predetermined frequency of retransmissions is received when a fragment block of second level transmission data is sent to a receiving side; shifting to a first layer receiving status if first layer receiving success information is received in the sending status; and shifting to a transmission completion status if second layer receiving success information is received in the sending status.
