Abstract: Techniques for cross channel occupancy time (COT) hybrid automatic repeat request (HARQ) feedback transmission for sidelink communication in unlicensed spectrum may be performed. In an example, a receiving user equipment (UE) may receive, from a transmitting UE, a first transmission in a first channel occupancy time (COT). The receiving UE may also determine a first feedback occasion is after a last slot of the first COT. The receiving UE may also determine one or more feedback configurations. The receiving UE may also transmit, to the transmitting UE, a feedback message indicating decoding of the first transmission in the first feedback occasion or a second feedback occasion based on the one or more feedback configurations.

Abstract: Wireless communications systems and methods related to performing listen-before-talk (LBT) before a transmission after a link switch in a frequency spectrum shared by multiple network operating entities are provided. A first wireless communication device receives, from a second wireless communication device, a first communication signal. The first wireless communication device determines a first measurement period in a first portion of a gap duration between the first communication signal and a second communication signal, the first portion being adjacent to a start time of the second communication signal. The first wireless communication device performs an LBT based at least in part on a first channel measurement in the first measurement period. The first wireless communication device transmits, to the second wireless communication device, the second communication signal based on the LBT.

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: Certain aspects of the present disclosure provide techniques for techniques for providing sidelink feedback. Certain aspects provide a method for wireless communication by a first user equipment (UE). The method generally includes receiving, from a second UE, one or more sidelink data messages and transmitting, to the second UE, via a first sidelink feedback channel resource, a first feedback message comprising one or more feedback bits associated with the one or more sidelink data messages, wherein: the first sidelink feedback channel resource comprises a first partial interlace group of a first interlace group of resource blocks, and the first partial interlace group comprises at least two first resource blocks.

Abstract: Wireless communications systems, apparatuses, and methods are provided. A method of wireless communication performed by a first sidelink user equipment (UE) may include receiving, from a second sidelink UE, a configuration associated with multiplexing a first physical sidelink feedback channel (PSFCH) having a first format with a second PSFCH having a second format, wherein the second format is different from the first format, receiving, from the second sidelink UE, one or more transport blocks (TBs), and transmitting, to the second sidelink UE based on the configuration, an acknowledgement/negative-acknowledgment (ACK/NACK) associated with the one or more TBs via the first PSFCH multiplexed with the second PSFCH.

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.

Abstract: Methods, systems, and devices for wireless communications are described. Some wireless communications systems may support signaling for channel access using multi-beam sensing. In some cases, a user equipment (UE) may transmit a capability message indicating a capability of the UE to support per-beam channel access procedures for communicating in one or more shared radio frequency spectrum. In some cases, the UE may receive, from a network entity, a control message indicating a channel occupancy configuration that is associated with the per-beam channel access procedures. Additionally, the UE may perform a per-beam channel access procedure for each beam of a set of beams and may communicate via one or more beams from the set of beams based on the channel occupancy configuration and the per-beam channel access procedures being successful for at least a subset of beams of the set of beams.

Abstract: Wireless communication systems and methods related to dynamic indications of uplink transmission parameters via configured grant-UCI (CG-UCI) are provided. A user equipment (UE) receives, from a base station (BS), a first configuration indicating a first configured grant (CG) resource and a first transmission parameter associated with the first CG resource. The UE determines a second transmission parameter for transmitting a data block in the first CG resource. The second transmission parameter is different from the first transmission parameter. The UE transmits, to the BS in the first CG resource, a transmission including the data block and configured grant-uplink control information (CG-UCI) indicating the second transmission parameter, where the data block is transmitted based on the second transmission parameter.
