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.

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.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, via a sidelink communication, an indication that another UE has reserved a first channel occupancy time (COT) resource of a plurality of COT resources. The UE may reserve a second COT resource of the plurality of COT resources via one or more slots associated with the first COT resource and using frequency division multiplexing (FDM) channel access, or transmit a communication, via the one or more slots associated with the first COT resource, using a different interlace than an interlace that is associated with the first COT resource. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless communication device may receive a configuration indicating SL synchronization communication resources occupying a first portion of a shared frequency band. The wireless communication device may transmit one or more SL synchronization communications occupying a second portion of the shared frequency band, where the second portion of the shared frequency band is larger than the first portion and includes the first portion.

Abstract: A method of wireless communication performed by a first wireless communication device may maintain a channel occupancy time (COT) in a shared frequency band during at least one physical sidelink feedback channel (PSFCH) instance. In some aspects, the method includes transmitting, in a first portion of a COT based on a listen-before talk (LBT), a first sidelink (SL) communication comprising SL communication information (SCI), the SCI indicating a second wireless communication device to transmit a signal in at least one gap symbol preceding a PSFCH resource. The method further includes receiving, from the second wireless communication device, the signal during the at least one gap symbol. The method further includes transmitting, in a second portion of the COT based on the LBT, a second SL communication, wherein the second portion of the COT is subsequent to the PSFCH resource.
