1. A method for wireless communications at a user equipment (UE), comprising:
monitoring, during a first sensing window, a first resource pool associated with sidelink control signaling;
selecting one or more sidelink control channel resources from the first resource pool based at least in part on the monitoring during the first sensing window, wherein each subchannel of the first resource pool associated with sidelink control signaling maps to a respective slot of a second resource pool associated with sidelink data signaling;
monitoring, during a second sensing window, at least a portion of the second resource pool associated with sidelink data signaling;
selecting one or more sidelink shared channel resources from the second resource pool based at least in part on the monitoring during the first sensing window the monitoring during the second sensing window, and each subchannel of the first resource pool mapping to the respective slot of the second resource pool;
transmitting, using a first sidelink control channel resource on a first subchannel of the first resource pool, a first sidelink control information message reserving the selected one or more sidelink control channel resources from the first resource pool and reserving the selected one or more sidelink shared channel resources from the second resource pool for a sidelink data message; and
transmitting the sidelink data message on the one or more reserved sidelink shared channel resources during a slot that maps to the first subchannel of the first resource pool.
