Abstract: Certain aspects of the present disclosure provide a user equipment (UE) that may receive an indication of a proximity discovery resource in a physical sidelink feedback channel (PSFCH) symbol from a network entity. The UE may transmit a proximity discovery request including the indication of the proximity discovery resource. The UE may receive a PSFCH sequence associated with the proximity discovery resource from other UEs that may respond to the proximity discovery request. The UE may transmit a bit map sequence indicative of the other UEs to the network entity. The network entity may determine a proximity between the UE and the other UEs based on the bit map sequence. The network entity may schedule the UE and the other UEs based on the proximity.

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: Aspects of the disclosure relate to a user equipment (UE) for establishing a sidelink communication channel with a wireless network and perform time resource allocation of channel-state information reference signals (CSI-RS), as well as collision handling. The UE may receive a physical sidelink shared channel (PSSCH) signal via the sidelink communication, where the PSSCH includes one or more interlaced physical resource blocks. The UE may process time-division multiplexed CSI-RS in one or more resource blocks for triggering the PSSCH signal.

Abstract: In the context of a slot of a sidelink (SL) communication frame of a user equipment (UE), the slot is configured with a resource element allocation comprising an SL synchronization signal block (S-SSB) occupying a plurality of less than all symbols of the slot, and a plurality of less than all subcarriers of a channel of the slot. The UE determines that an occupied channel bandwidth (OCB) constraint for the slot across the channel will not be met with the resource element allocation. The UE then multiplexes, in response to the determining, a reference signal (RS) across the symbols occupied by the S-SSB in a plurality of resource blocks of the channel not occupied by the S-SSB to meet the OCB constraint. The UE then transmits the slot with the S-SSB and the multiplexed RS.
