A RETRANSMISSION METHOD WITH SOFT COMBINING IN A TELECOMMUNICATIONS SYSTEM

摘要

Automatic repeat request (ARQ) mechanism (such as II/III types are hybrid) carries out soft or hard) it combines (including the grouping pattern that initially will be sent and retransmit, for retransmitting the grouping of mistake. According to the present invention, each repeating transmission, when there are out band signallings (RNC) from transmitter (17) to receiver (UE), that is explicitly indicated, such as, time or physical location, the first transmission grouping carry out, therefore can be grouped retransmitting version with previous version (one or more). Soft merging requires initial grouping identical as the grouping retransmitted. In one embodiment of the invention, in order to overcome this problem, some information need to change initial transmission and retransmit between it is (multiple) grouping by transmission band outside with other out band signalling information (17). Therefore, the packet retransmission can with it is above-mentioned be to maintain constant requirement it is identical be grouped in soft merging meet.
