Hybrid automatic repeat request associations for downlink semi-persistent scheduling

A method of wireless communication using semi-persistent scheduling, comprising:

• receiving at a user equipment a first initial transmission associated with a first Hybrid Automatic Repeat Request (HARQ) process;
• receiving at the user equipment a second initial transmission associated with a second HARQ process;
• and
• receiving at the user equipment at least one retransmission associated with the first HARQ process,
• wherein when the second initial transmission occurs before the at least one retransmission, the second HARQ process is assigned an HARQ process ID that is different from an HARQ process ID assigned to the first HARQ process, and
• wherein when the second initial transmission occurs after the at least one retransmission, the second HARQ process is assigned an HARQ process ID that is the same as an HARQ process ID assigned to the first HARQ process.
