1. A method of wireless communication performed by a user equipment (UE), comprising:
attempting, for up to a threshold quantity of transmission opportunities of a plurality of transmission opportunities of a channel occupancy time in a transmission opportunity aggregation deployment, a listen-before-talk (LBT) procedure, wherein the LBT procedure is a category-2 LBT procedure performed to reserve resources for a sounding reference signal (SRS) communication; and
selectively transmitting, based at least in part on the LBT procedure being successful within the threshold quantity of transmission opportunities, one or more repetitions of an uplink transmission in one or more remaining transmission opportunities of the plurality of transmission opportunities, or
determining, based at least in part on the LBT procedure not being successful within the threshold quantity of transmission opportunities, that a failure of the uplink transmission has occurred.
