1. An apparatus for wireless communication at a receiver, comprising:
one or more memories storing processor-executable code; and
one or more processors coupled with the one or more memories, at least one processor of the one or more processors configured to cause the receiver to:
receive, from two or more transmitters, two or more sidelink control informations (SCIs) that schedule channel occupancy time (COT) resources for the two or more transmitters;
transmit, to a transmitter of the two or more transmitters, an acknowledgement (ACK) in accordance with the two or more SCIs not being associated with a same COT resource, the ACK being transmitted via a time division multiplexed or a frequency division multiplexed mini-slot, the ACK being transmitted before a listen-before-talk (LBT) and physical sidelink shared channel (PSSCH) transmission corresponding to an originally scheduled COT resource; and
receive, from the transmitter, the PSSCH transmission, the PSSCH transmission adjustable at the transmitter according to the ACK.
