Abstract
A method implemented by a transmitting device includes sensing, by the transmitting device during a sensing slot using a sensing beam, an availability of a channel for performing at least one transmission using at least one transmit beam; determining, by the transmitting device, a sensing threshold in accordance with the sensing beam and the at least one transmit beam; and determining, by the transmitting device, that the channel is idle in accordance with the sensing threshold, and based thereon, transmitting, by the transmitting device, on the channel using the at least one transmit beam.
