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: Certain aspects of the present disclosure provide techniques for implicitly determining a receive beam for a UE to use for received signal strength indicator (RSSI) measurement. For example, the UE may perform RSSI measurement with a receive beam implicitly determined at the UE and report the RSSI to a network entity.
