A REPEAT CONTROL METHOD IN ENHANCED UPLINK ASYNCHRONOUS HYBRID AUTOMATIC REPEAT REQUEST

摘要

A repeat control method in the enhanced uplink asynchronous hybrid automatic repeat request (HARQ) includes the following steps: (1) the network side adding a parameter of retransmission timer in the HARQ Profile of each dedicated media access control (MAC-d) entity flow in the user equipment, and the user equipment configures the value of the retransmission timer of the enhanced media access control entity (MAC-e) protocol data unit (PDU) according to the parameter of the retransmission timer; (2) the user equipment uses the value of the retransmission timer and the maximum number of retransmissions to control the retransmission. The radio bearer QoS delay requirement and the cooperation work between the sender and the receiver are implemented.
