Abstract:
1. A method for assigning hybrid automatic repeat request (HARQ) process ID, comprising: determining whether 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 if it is determined that the retransmission of the first initial SPS transmission having the first HARQ process ID is expected to occur after the second initial transmission, wherein the second HARQ process ID is different from the first HARQ process ID, and wherein the second HARQ process ID is explicitly assigned via physical downlink control channel (PDCCH) signaling, and assigning the first HARQ process ID to the second initial transmission if it is determined that the retransmission of the first initial SPS transmission having the first HARQ process ID is not expected to occur after the second initial transmission.
