Abstract

A repeat control method in enhanced uplink asynchronous hybrid automatic repeat request (HARQ) includes the following steps: (1) the network side adding a repeat timer parameter in the HARQ attribute of each dedicated media access control (MAC-d) entity flow, the user terminal setting the repeat timer value in the enhanced media access control (MAC-e) entity protocol data unit (PDU) according to the repeat timer parameter; (2) the user terminal performing the repeat control utilizing the repeat timer value in cooperation with the maximum repeat number. The wireless bearer QoS requirement and the cooperation working between the sender and the receiver are implemented.
