Abstract: Various aspects of the present disclosure generally relate to wireless communication. Some aspects more specifically relate to sidelink communications and physical sidelink feedback channel (PSFCH) transmissions. A channel occupancy time (COT) initiating user equipment (UE) may obtain PSFCH information that indicates a plurality of PSFCH transmission occasions. The COT initiating UE may transmit a sidelink communication to a responding UE. In some aspects, the COT initiating UE may receive, from the responding UE, hybrid automatic repeat request (HARQ) feedback in each PSFCH transmission occasion of the plurality of PSFCH transmission occasions. In some other aspects, the COT initiating UE may receive, from the responding UE, HARQ feedback in at least the first PSFCH transmission occasion of the plurality of PSFCH transmission occasions.

Abstract: A method for wireless communication at a first user equipment (UE) includes performing, in a shared radio frequency band, a listen-before-talk (LBT) procedure for a channel occupancy time (COT). The method also includes selecting a first or second starting symbol for an initial slot based on a timing associated with the LBT procedure indicating a clearance, the initial slot having a first or second total number of symbols in accordance with selecting the first starting symbol or the second starting symbol. The method further includes selecting either a first or second demodulation reference signal (DM-RS) pattern from a group of DM-RS patterns in accordance with the initial slot having the first total number of symbols or the initial slot having the second total number of symbols. The method also includes transmitting, during the COT, sidelink information to a second UE via a sequence of slots that include the initial slot.
