Methods for distance-based hybrid automatic repeat request (HARQ) feedback transmission

An apparatus for wireless communication by a first user-equipment (UE), comprising:

• a memory;
• and
• one or more processors coupled to the memory, the one or more processors and the memory being configured to:
• monitor for a data transmission from a second UE;
• receive an indication of a first zone identifier (ID) associated with multiple zones;
• determine a nearest zone to the first UE of the multiple zones, wherein the multiple zones are determined based at least in part on the indication of the first zone ID;
• determine a distance between the first UE and the second UE based on the first zone ID, wherein the determined distance comprises a distance between the first UE and the nearest zone;
• and
• transmit hybrid automatic repeat request (HARQ) feedback for the data transmission based at least on the distance.

A non-transitory computer-readable medium having instructions stored thereon to cause a first user-equipment (UE) to:

• monitor for a data transmission from a second UE;
• receive an indication of a first zone identifier (ID) associated with multiple zones;
• determine a nearest zone to the first UE of the multiple zones, wherein the multiple zones are determined based at least in part on the indication of the first zone ID;
• determine a distance between the first UE and the second UE based on the first zone ID, wherein the determined distance comprises a distance between the first UE and the nearest zone;
• and
• transmit hybrid automatic repeat request (HARQ) feedback for the data transmission based at least on the distance.
