1. 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 a sidelink message in a first sidelink transmission occasion of a set of sidelink transmission resources of a sidelink resource pool shared by a first radio access technology and a second radio access technology, the set of sidelink transmission resources and the sidelink message associated with the first radio access technology;
map, based at least in part on a position of the first sidelink transmission occasion in the sidelink resource pool, the first sidelink transmission occasion to a physical sidelink feedback channel occasion associated with the first radio access technology;
map, starting with an earliest of sidelink transmission occasions mapped to the physical sidelink feedback channel occasion, each subchannel of the sidelink transmission occasions to a respective sidelink feedback resource of the physical sidelink feedback channel occasion; and
transmit, via a resource of the physical sidelink feedback channel occasion mapped to a subchannel carrying sidelink control information associated with the sidelink message, a feedback message corresponding to the sidelink message.
