Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a physical sidelink shared channel (PSCCH) transmission that uses unlicensed spectrum. The UE may select a resource block (RB) configuration for one or more resource blocks (RBs) that are associated with a physical sidelink feedback channel (PSFCH) transmission, the RB configuration being based at least in part on the unlicensed spectrum. The UE may transmit an acknowledgement (ACK)/negative acknowledgement (NACK) response to the PSCCH transmission based at least in part on using the PSFCH and the RB configuration for the one or more RBs. Numerous other aspects are described.

Abstract: This disclosure provides systems, methods and apparatuses for indicating sidelink processes for sidelink feedback. A second user equipment (UE) may request hybrid automatic repeat request (HARQ) responses from a first UE for a particular set of sidelink processes over a physical sidelink feedback channel. To indicate multiple sidelink processes, the second UE may indicate, in sidelink control information, a window of sidelink processes. The window may be a sliding window that starts with a starting sidelink process and extends through other sidelink processes. The second UE may transmit data for the sidelink processes in the sliding window and receive feedback for the indicated sidelink processes. In some aspects, the first UE may select, in coordination with the second UE, the sidelink processes for which feedback is to be provided.

Abstract: Wireless communications systems, apparatuses, and methods are provided. A method of wireless communication performed by a first sidelink user equipment (UE) may include transmitting a sidelink synchronization signal block (S-SSB) in a first S-SSB slot of an S-SSB burst, and communicating a sidelink communication in at least one remaining S-SSB slot of the S-SSB burst.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a sidelink slot format, wherein the sidelink slot format indicates a configuration of sidelink feedback resources. The UE may measure a signal, associated with a channel access procedure, after a first symbol of a first sidelink slot and prior to a mini-slot of the first sidelink slot, and wherein the sidelink slot format indicates that the first sidelink slot is associated with the sidelink feedback resources. The UE may transmit, using a transmission starting location of the mini-slot or of a symbol of a second sidelink slot, a sidelink communication based at least in part on the measurement of the signal, wherein a format of the sidelink feedback resources is based at least in part on the transmission starting location. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may obtain a nominal resource block value associated with one or more allocated subchannels for a sidelink communication. The UE may identify a number of physical sidelink shared channel (PSSCH) resource elements to be used for a transport block size calculation based at least in part on the nominal resource block value. The UE may transmit the sidelink communication, and reserve one or more resources for one or more respective retransmissions of the sidelink communication, based at least in part on the number of PSSCH resource elements. Numerous other aspects are described.

Abstract: Systems, devices, and methods for mapping wideband sidelink (SL) resources to SL feedback resources are provided. For example, a method of wireless communication performed by a user equipment (UE) comprises: receiving, based on at least a first interlace of resource blocks (RBs) and based on two or more RB-sets of a shared frequency band, a SL communication; and transmitting, using at least a second interlace of RBs and using resources from at least one RB-set of the two or more RB-sets of the shared frequency band, a SL feedback communication for the SL communication. In some aspects, the transmitting the SL feedback communication is based on a mapping of the two or more RB-sets to the at least one RB-set.
