Distance and angle based sidelink HARQ

A method of wireless communication performed by a receiver, comprising:

• receiving, from a transmitter, a sidelink communication and sidelink control information (SCI), associated with the sidelink communication, that indicates one or more distance parameter and angle parameter combinations for hybrid automatic repeat request (HARQ) feedback, wherein the one or more distance parameter and angle parameter combinations include a distance range or distance threshold;
• determining that the receiver satisfies a distance parameter and angle parameter combination of the one or more distance parameter and angle parameter combinations;
• and
• transmitting, based at least in part on determining that the receiver satisfies the distance parameter and angle parameter combination, the HARQ feedback for the sidelink communication to the transmitter on a sidelink, wherein the HARQ feedback is transmitted in a time-domain resource and a frequency-domain resource associated with the distance parameter and angle parameter combination.

A transmitter for wireless communication, comprising:

• a memory;
• and
• one or more processors coupled to the memory, the one or more processors configured to:
• transmit a sidelink communication and sidelink control information (SCI), associated with the sidelink communication, that indicates one or more distance parameter and angle parameter combinations for hybrid automatic repeat request (HARQ) feedback, wherein the one or more distance parameter and angle parameter combinations include a distance range or distance threshold;
• and
• receive the HARQ feedback, for the sidelink communication, on a sidelink and from a receiver that satisfies a distance parameter and angle parameter combination of the one or more distance parameter and angle parameter combinations, wherein the HARQ feedback is received in a time-domain resource and a frequency-domain resource associated with the distance parameter and angle parameter combination.
