1. An apparatus for wireless communication at a first user equipment (UE), comprising:
at least one processor;
memory coupled with the at least one processor; and
instructions stored in the memory and executable by the at least one processor to cause the apparatus to:
receive, from a network device, control signaling comprising an indication of a set of resources of a sidelink channel available for sidelink communication with a second UE, an indication of a resource allocation mode type for the set of resources, and an indication that the first UE is one of either a transmitter or a receiver for the sidelink communication with the second UE for the set of resources;
receive, from the network device, a sidelink preemption indication indicating that at least a first resource from the set of resources is preempted for an uplink or downlink communication;
communicate, with the second UE, a first reservation signal to reserve the first resource based at least in part on the resource allocation mode type indicated by the control signaling and further based at least in part on the sidelink preemption indication being received less than a threshold amount of time prior to the first resource; and
communicate a sidelink transmission over the sidelink channel with the second UE based at least in part on the sidelink preemption indication and the control signaling, wherein communication of the sidelink transmission is via the first resource and based at least in part on reservation of the first resource.
