1. A method for wireless communication at a secondary user equipment (UE), comprising:
receiving, at the secondary UE, a first grant to conditionally transmit one or more data messages over a first set of resources, transmission of the one or more data messages conditional on completion, by the secondary UE, of a detection procedure to monitor a second set of resources for one or more over-the-air signals transmitted by a primary UE pursuant to a second grant that is associated with the first grant, wherein the first set of resources at least partially overlaps the second set of resources;
monitoring, as part of the detection procedure, for the one or more over-the-air signals from the primary UE, the one or more over-the-air signals indicative of whether the second set of resources is used by the primary UE;
determining, based at least in part on the monitoring, that one or more conditions for transmission of the one or more data messages have been satisfied via the detection procedure;
transmitting the one or more data messages over the first set of resources based at least in part on the one or more conditions being satisfied;
wherein monitoring for the one or more over-the-air signals from the primary UE comprises:
monitoring, as part of the detection procedure, for an early occupancy indication transmitted by the primary UE prior in time to both the first set of resources and the second set of resources; and
wherein monitoring for the early occupancy indication comprises:
monitoring for a sounding reference signal from the primary UE, wherein the one or more conditions are satisfied via the detection procedure upon failure by the secondary UE to detect the sounding reference signal as the early occupancy indication from the primary UE.
