Abstract
This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for a retransmission protocol that utilizes compressed feedback. Various implementations relate generally to a compressed feedback technique for hybrid automatic repeat request (HARQ). Upon receiving a compressed feedback value, a sending device may generate a retransmission codeblock. The retransmission codeblock may be derived from multiple codeblocks in a set of codeblocks. A receiving device can use the retransmission codeblock to obtain any failed codeblock in the set of codeblocks based on all other previously decoded codeblocks in the set of codeblocks. Thus, the receiving device does not need to indicate which codeblock in the set failed, but only needs to send a compressed feedback value that indicates which sets of codeblocks have had a single codeblock failure.
