Abstract: Methods and devices utilizing sidelink transmission between user equipment (UEs) for HARQ retransmission are provided. The sidelink HARQ retransmissions include data from the initial transmission or an outer coded version thereof. HARQ feedback from the targeted receiver of the initial transmission may identify code block groups and/or individual code blocks the target receiver did not successfully decode. A UE that has not successfully decoded an entire transport block, may still cooperate in HARQ retransmission for the targeted receiver of the transport block by retransmitting at least a subset of the code block groups that it was able to successfully decode for the transport block.
