1. A method for wireless communications at a full-duplex wireless device, comprising:
identifying a first threshold value and a second threshold value that exceeds the first threshold value for a channel access procedure on a shared channel and a self-interference threshold value for the channel access procedure;
performing a first sensing operation for the channel access procedure to detect a first amount of energy on the shared channel;
performing a self-interference measurement of a transmission from the full-duplex wireless device, the self-interference measurement being performed based at least in part on the first amount of energy on the shared channel occurring between the first threshold value and the second threshold value; and
transmitting a message via the shared channel based at least in part on the self-interference measurement exceeding the self-interference threshold value.
