Sidelink feedback transmission and feedback resource determination

A method for wireless communication at a device, comprising:

• transmitting a data transmission;
• determining a slot to receive a hybrid automatic repeat request feedback based at least in part on the data transmission;
• determining one or more hybrid automatic repeat request feedback resources in the slot to receive the hybrid automatic repeat request feedback, wherein the one or more hybrid automatic repeat request feedback resources in the slot comprises a set of frequency resources associated with the slot, wherein determining the one or more hybrid automatic repeat request feedback resources in the slot is based at least in part on one or more of a first device identifier associated with the device or a second device identifier associated with a second device;
• and
• receiving the hybrid automatic repeat request feedback using the one or more hybrid automatic repeat request feedback resources in the slot and using one or more cyclic shifts that are each associated with a feedback type of the one or more hybrid automatic repeat request feedback resources, wherein the feedback type comprises an acknowledgment type or a negative acknowledgment type.

An apparatus for wireless communication, comprising:

• one or more memories storing processor-executable code;
• and
• one or more processors coupled with the one or more memories and individually or collectively operable to execute the code to cause the apparatus to:
• receive a data transmission;
• determine a slot to transmit a hybrid automatic repeat request feedback based at least in part on the data transmission;
• determine one or more hybrid automatic repeat request feedback resources in the slot to transmit the hybrid automatic repeat request feedback, wherein the one or more hybrid automatic repeat request feedback resources in the slot comprises a set of frequency resources associated with the slot, wherein determining the one or more hybrid automatic repeat request feedback resources in the slot is based at least in part on one or more of a first device identifier associated with the apparatus or a second device identifier associated with a second apparatus;
• and
• transmit the hybrid automatic repeat request feedback using the one or more hybrid automatic repeat request feedback resources in the slot and using one or more cyclic shifts based at least in part on a feedback type of the one or more hybrid automatic repeat request feedback resources, wherein the feedback type comprises an acknowledgment type or a negative acknowledgment type.
