Sensing-based distributed scheduling of event-based mission critical (mc) vehicle-to-everything (v2x) traffic

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:
• decode, at the vUE, mission critical (MC) sidelink control information (SCI) (MC-SCI) in one or more SCI messages from a physical sidelink control channel (PSCCH);
• identify, at the vUE, a revoke indicator in the MC-SCI;
• revoke, at the vUE, one or more revocable resources from one or more scheduled low-priority resources when the revoke indicator indicates revocation;
• and
• decode, at the vUE, MC resources including MC data with a selected number of repetitions in the one or more revocable resources when the revoke indicator indicates the revocation;
• and
• a memory interface configured to store MC-SCI in a memory.

At least one non-transitory machine readable storage medium having instructions embodied thereon for sensing-based distributed scheduling of event-based mission critical (MC) vehicle-to-everything (V2X) traffic, the instructions when executed by one or more processors at a vehicle-capable user equipment (vUE) perform the following:

• sensing, 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;
• identifying, 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;
• selecting, at the vUE, revocable resources from one or more scheduled low-priority resources based on the SCI sensed for the SPS resource selection;
• and
• encoding, 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.
