1. An apparatus of a vehicle-capable user equipment (vUE) operable for sensing-based distributed scheduling of event-based mission critical (MC) vehicle-to-everything (V2X) traffic, the apparatus comprising:
one or more processors configured to:
sense, at the vUE, sidelink control information (SCI) for semi-persistent scheduling (SPS) resource selection from one or more SCI messages received in one or more physical sidelink control channels (PSCCHs) from one or more neighboring vUEs;
identify, at the vUE:
a number of MC resources to transmit event-based MC data with a selected number of repetitions within a latency budget, wherein the MC resources include one or more of MC-SCI or MC data with the selected number of repetitions; and
a number of available resources to transmit event-based MC data within the latency budget;
select, at the vUE, revocable resources from one or more scheduled low-priority resources based on the SCI sensed for the SPS resource selection;
encode, at the vUE for transmission to the one or more neighboring vUEs, the MC resources within the available resources and the revocable resources when the number of MC resources is greater than the number of available resources; and
encode, at the vUE for transmission to the one or more neighboring vUEs, resource reservation transmission time interval (TTI) information in the MC-SCI, the resource reservation TTI information representing a plurality of TTIs used by the encoded MC resources; and
a memory interface configured to store the MC resources in a memory.
