    Abstract: Methods, systems, and devices for wireless communication are described. In some systems, a user equipment (UE) may receive a first sidelink message associated with a sidelink feedback transmission occasion and a second sidelink message also associated with the sidelink feedback transmission occasion. The UE may provide a type of feedback information via the sidelink feedback transmission occasion based on the first sidelink message and the second sidelink message both being associated with the sidelink feedback transmission occasion. The provided type of feedback information may be based on a quantity of one or more additional sidelink feedback transmission occasions subsequent to the sidelink feedback transmission occasion that are also available for transmission of either first feedback associated with the first sidelink message or second feedback associated with the second sidelink message.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may initiate a wideband channel occupancy time (COT) associated with a plurality of resource block (RB) sets. The UE may transmit a plurality of sidelink synchronization signal block (S-SSB) repetitions in at least a portion of the plurality of RB sets being occupied by the wideband COT, wherein a quantity of S-SSB repetitions, of the plurality of S-SSB repetitions, or a transmit power of at least one S-SSB repetition, of the plurality of S-SSB repetitions, is based at least in part on a power control parameter. Numerous other aspects are described.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a receiver may receive, from two or more transmitters, two or more sidelink control informations (SCIs) that schedule channel occupancy time (COT) resources for the two or more transmitters. The receiver may transmit, to a transmitter of the two or more transmitters, an acknowledgement or negative acknowledgement (A/N) feedback via a mini-slot carrying a physical sidelink feedback channel (PSFCH) or sidelink feedback information (SLFI) with SCI. The A/N feedback may be transmitted before a listen-before-talk (LBT) and physical sidelink shared channel (PSSCH) transmission. The receiver may receive, from the transmitter using a COT resource, the PSSCH transmission based at least in part on the A/N feedback. The LBT and the PSSCH transmission may be adjustable at the transmitter based at least in part on the A/N feedback. Numerous other aspects are described.

    Abstract: Aspects of the disclosure relate to a user equipment (UE) for establishing a sidelink communication channel and receive mapped channel state information-reference signals (CSI-RS) over a plurality of PSSCH resource blocks. The mapped CSI-RS may be interlaced with resource elements in at least a portion of the plurality of PSSCH resource blocks. The CSI-RS received over the plurality of PSSCH blocks is then processed to determine a channel quality of the sidelink channel from the portion of the plurality of PSSCH resource blocks including the mapped CSI-RS.
