ALLOCATION OF DIFFERENT HARQ PROCESS IDENTIFIERS TO DIFFERENT INITIAL SEMI-PERSISTENT SCHEDULING IN ORDER TO SOLVE RETRANSMISSIONS AMBIGUITY WHEN DIFFERENT HARQ PROCESSES OVERLAP

摘要

A method for assigning hybrid automatic repeat request (HARQ) process ID is provided. The method includes, when a retransmission associated with a first initial semi -persistent scheduling (SPS) transmission having a first HARQ process ID is expected to occur after a second initial transmission previously configured with SPS resource, explicitly assigning a second HARQ process ID to the second initial transmission wherein the second HARQ process ID is different from the first HARQ process ID.
