Abstract: Methods, systems, and devices for wireless communications are described. A first UE may receive a message indicating a configuration or a sidelink discovery burst transmission window. The configuration may include time periods for transmitting multiple sidelink synchronization signals. The first UE may perform a channel access procedure during the sidelink discovery burst transmission window. The first UE may perform the channel access procedure for transmitting one or more of the sidelink synchronization signals according to a pattern indicated by the configuration. The pattern may be based on a quasi co-location relationship between associated pairs of the sidelink synchronization signals. The first UE may transmit the one or more sidelink synchronization signals to a second UE in accordance with the pattern indicated by the configuration.

Abstract: Certain aspects of the present disclosure provide techniques for determining if a first sensing beam is eligible for use in channel sensing by a device under test (DUT) for at least a first transmission beam, generally including evaluating the first sensing beam against eligibility criterion based on measurement of sensing gain for the first sensing beam in multiple directions and declaring the first sensing beam eligible for channel sensing for the first transmission beam when the first sensing beam satisfies the eligibility criterion.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a channel occupancy time (COT) duration indication that indicates a first COT duration associated with a first channel occupancy initiated by the base station. The UE may initiate, during a time duration that is outside of the first COT duration and based at least in part on performing a listen-before-talk procedure, a second channel occupancy having a second COT duration. Numerous other aspects are described.

Abstract: Wireless communications systems and methods related to channel access in a shared radio frequency band in an unlicensed spectrum or a shared spectrum are provided. A wireless communication device determines a channel access procedure based on whether one or more channel access conditions are satisfied for accessing an unlicensed frequency band. The one or more channel access conditions are associated with at least one of sensing across multiple channel occupancy times (COTs), a transmission beam characteristic, a transmit power, a transmission duty cycle, or a beam dwell time. The wireless communication device transmits, based on the channel access procedure, a communication signal in the unlicensed frequency band.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may sense, using a beam sweeping operation during a channel check period, a shared wireless communication channel. The wireless communication device may perform a wireless communication action based at least in part on whether a high priority wireless communication signal is detected during the beam sweeping operation. Numerous other aspects are described.
