Certain aspects of the present disclosure provide techniques for requesting inter-UE coordination messages for sidelink communications. An example method for wireless communications by a first user equipment (UE) generally includes sending a sidelink communication on a first set of one or more subchannels in a first slot of sidelink resource pool, performing channel sensing on a second set of one or more subchannels in the first slot, and selecting one or more resources for a subsequent sidelink communication in at least a second slot of the sidelink resource pool on the channel sensing.

MULTIPLE THRESHOLDS FOR UNLICENSED CHANNEL ACCESS FOR FULL-DUPLEX NODES

Methods, systems, and devices for wireless communications are described. A full-duplex device may perform a channel access procedure using multiple threshold values to determine whether self-interference at the full-duplex device is affecting the channel access procedure. For example, if a first amount of energy detected during a first sensing operation of the channel access procedure is determined to be between a first threshold value and a second threshold value, the full-duplex device may perform a self-interference measurement on the shared channel and may transmit on the shared channel if the self-interference measurement exceeds a self-interference threshold value. Additionally or alternatively, if the self-interference measurement does not exceed the self-interference threshold value, the full-duplex device may refrain from transmitting on the shared channel. In some examples, the self-interference measurement may include a correlation measurement, a signal-to-noise ratio (SNR) measurement, or a combination thereof.
