Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for a user equipment (UE) to provide listen before talk (LBT) assistance to a transmitting device. The UE may receive a pre-grant (PG) indicating a plurality of beams. The UE may performing a LBT procedure on each beam of the indicated plurality of beams. The UE may transmit an acknowledgment to the pre-grant (APG) as a waveform that indicates that the LBT procedure for one or more of the indicated plurality of beams was successful. The waveform may be a sounding reference signal (SRS) with a sequence that indicates that the LBT procedure was successful.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment may receive a signal in an automatic gain control resource and may receive a physical sidelink feedback channel message based on a gain for reception of the first physical sidelink feedback channel message, where the gain is based on receiving the signal. In some aspects, the first physical sidelink feedback channel message may be one of a set of physical sidelink feedback channel messages time-division multiplexed over a set of contiguous time resources. Additionally, or alternatively, the user equipment may receive a sidelink message after receiving the physical sidelink feedback channel message using a second gain, where the second gain is based on receiving a second signal in a second automatic gain control resource that occurs before the first automatic gain control resource.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for channel access for wireless communications. One aspect provides a method for wireless communications at a user equipment (UE). The method generally includes obtaining a channel occupancy time (COT) structure information (COT-SI) message and obtaining at least one downlink control information (DCI) indicating multiple beams and listen before talk (LBT) scheme indications associated with the multiple beams. The method generally includes determining an LBT scheme to be used for transmission via each of the multiple beams based on the LBT scheme indications and the COT-SI message, and outputting signaling for transmission on each of the multiple beams based on the LBT scheme.
