Prioritization between feedback transmissions and receptions over sidelink

A method for wireless communications at a first wireless device, comprising:

• receiving, from a second wireless device, one or more sidelink control information messages scheduling a first multi-bit feedback and indicating a plurality of priority field values associated with respective feedback bits of the first multi-bit feedback, wherein a first priority of the first multi-bit feedback corresponds to a highest priority of the plurality of priority field values;
• determining that a first set of resources allocated for the first multi-bit feedback at least partially overlaps with a second set of resources allocated for a second feedback having a second priority;
• selecting one of the first multi-bit feedback or the second feedback based at least in part on the first priority of the first multi-bit feedback and the second priority of the second feedback;
• and
• transmitting or receiving, the selected one of the first multi-bit feedback or the second feedback.

An apparatus for wireless communications at a first wireless device, comprising:

• means for receiving, from a second wireless device, one or more sidelink control information messages scheduling a first multi-bit feedback and indicating a plurality of priority field values associated with respective feedback bits of the first multi-bit feedback, wherein a first priority of the first multi-bit feedback corresponds to a highest priority of the plurality of priority field values;
• means for determining that a first set of resources allocated for the first multi-bit feedback at least partially overlaps with a second set of resources allocated for a second feedback having a second priority;
• means for selecting one of the first multi-bit feedback or the second feedback based at least in part on the first priority of the first multi-bit feedback and the second priority of the second feedback;
• and
• means for transmitting or receiving, the selected one of the first multi-bit feedback or the second feedback.

A non-transitory computer-readable medium storing code for wireless communications at a first wireless device, the code comprising instructions executable by a processor to:

• receive, from a second wireless device, one or more sidelink control information messages scheduling a first multi-bit feedback and indicating a plurality of priority field values associated with respective feedback bits of the first multi-bit feedback, wherein a first priority of the first multi-bit feedback corresponds to a highest priority of the plurality of priority field values;
• determine that a first set of resources allocated for the first multi-bit feedback at least partially overlaps with a second set of resources allocated for a second feedback having a second priority;
• select one of the first multi-bit feedback or the second feedback based at least in part on the first priority of the first multi-bit feedback and the second priority of the second feedback;
• and
• transmit or receive, the selected one of the first multi-bit feedback or the second feedback.
