1. An apparatus for wireless communications at a first user equipment (UE), comprising:
one or more processors;
one or more memories coupled with the one or more processors; and
instructions stored in the one or more memories and executable by the one or more processors to cause the apparatus to:
receive control signaling indicating a set of resource pools available for sidelink communications;
transmit a sidelink control information message indicating a reservation of a resource pool of the set of resource pools, wherein the reservation indicates a priority level associated with low latency data, wherein the priority level preempts one or more lower priority level reservations of the resource pool, wherein the priority level is based at least in part on a remaining delay budget associated with the low latency data being less than a threshold, and wherein the remaining delay budget is based at least in part on a sidelink air interface delay;
receive, from a third UE and prior to transmitting the sidelink control information message, third control signaling indicating a second reservation of the resource pool, wherein the second reservation indicates a second priority level lower than the priority level, and wherein transmitting the sidelink control information message that indicates the reservation of the resource pool is based at least in part on the second priority level being lower than the priority level; and
transmit, to a second UE via the resource pool, a sidelink message comprising the low latency data.
