Hybrid automatic repeat request management method for improving transmission quality
First Claim
1. A method of managing at least one Hybrid Automatic Repeat reQuest (HARQ) process in a wireless communications system, comprising;
- determining a priority of the HARQ process according to a transmission success rate of the HARQ process;
determining a priority of a data unit to be transmitted; and
utilizing a transmitter to transmit the data unit according to the priority of the data unit and the priority of the HARQ process.

Abstract
The present invention to provide methods and related controllers that manage HARQ processes in a wireless communications system. The present invention provides a method and related controller to map data units (e.g. PDU) of importance that is to be transmitted to a HARQ process having a higher transmission success rate to prevent the data units from being transmitted via a HARQ process having more transmission failures. In addition, the present invention also provides a method and a related controller to force a HARQ process to retransmit a data unit that has been correctly received by a receiving end to reduce the latency of retransmission caused by a possible transmission failure occurring between a MAC layer and a RLC layer at the receiving end.
