In some aspects, a transmitting node may perform a directional listen-before-talk (LBT) using a sensing beam. The transmitting node may start a channel occupancy time (COT) after the directional LBT based at least in part on one of a COT claiming signal or a time stamp. The transmitting node may perform, to a receiving node, one or more transmissions during the COT using one or more transmit beams that are included in the sensing beam. Numerous other aspects are described. ## Claims ### Claim 1 A transmitting node for wireless communication, comprising: one or more memories comprising processor-executable instructions; and one or more processors, configured to execute the processor-executable instructions and cause the transmitting node to: perform a directional listen-before-talk (LBT) using a sensing beam; transmit a channel occupancy time (COT) claiming signal, after the directional LBT, wherein the transmission of the COT claiming signal starts a COT and indicates that a channel, associated with the COT, is shareable; and perform, to a receiving node, one or more transmissions during the COT using one or more transmit beams that are included in the sensing beam. ### Claim 2 (depends on 1) The transmitting node of claim 1, wherein the one or more processors, to start the COT, are further configured to cause the transmitting node to transmit the COT claiming signal. ### Claim 3 (depends on 1) The transmitting node of claim 1, wherein the one or more processors are further configured to cause the transmitting node to transmit the COT claiming signal using the sensing beam. ### Claim 4 (depends on 1) The transmitting node of claim 1, wherein the one or more processors are further configured to cause the transmitting node to transmit the COT claiming signal using a transmit beam selected from the one or more transmit beams that are included in the sensing beam. ### Claim 5 (depends on 1) The transmitting node of claim 1, wherein a transmit beam included in the one or more transmit beams is eligible based at least in part on the transmit beam being included in the sensing beam. ### Claim 6 (depends on 1) The transmitting node of claim 1, wherein a transmit beam included in the one or more transmit beams is eligible based at least in part on the transmit beam being associated with an energy detection threshold that is greater than or equal to an energy detection threshold associated with the sensing beam. ### Claim 7 (depends on 1) The transmitting node of claim 1, wherein the directional LBT is adequate for transmitting on the one or more transmit beams based at least in part on the sensing beam including the one or more transmit beams. ### Claim 8 (depends on 1) The transmitting node of claim 1, wherein the directional LBT is adequate for transmitting on the one or more transmit beams based at least in part on an energy detection threshold associated with the sensing beam being less than or equal to a minimum energy detection threshold associated with the one or more transmit beams. ### Claim 9 A method of wireless communication performed by a transmitting node, comprising: performing a directional listen-before-talk (LBT) using a sensing beam;
