Multiple sidelink feedback channel occasion procedures

An apparatus for wireless communications at a first user equipment (UE), comprising:

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• receive sidelink data in a sidelink channel;
• perform a listen-before-talk procedure to identify availability of a first set of feedback transmission time intervals in a sidelink feedback channel;
• refrain from transmitting a first negative acknowledgment message during the first set of feedback transmission time intervals based at least in part on the listen-before-talk procedure;
• and
• monitor the first set of feedback transmission time intervals for a second negative acknowledgment message transmitted by at least a second UE.

• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• receive a first sidelink data in a sidelink channel;
• and
• transmit feedback information for the first sidelink data in a first set of feedback transmission time intervals in a sidelink feedback channel based at least in part on a prioritization of the feedback information for the received first sidelink data.
