Semi-persistent scheduling mechanisms for vehicle-to-vehicle communication

An apparatus for wireless communication, comprising:

• a memory;
• and
• at least one processor coupled to the memory and configured to:
• determine a plurality of resource patterns required for vehicle-to-vehicle (V2V) communications prior to obtaining an activation grant for a resource assignment for the V2V communications from a base station;
• send a semi-persistent schedule (SPS) request including assistance information, the assistance information associated with the plurality of resource patterns to the base station, wherein each resource pattern of the plurality of resource patterns is associated with a distinct V2V communication from a user equipment (UE);
• receive, from the base station, a response associated with at least one resource pattern of the plurality of resource patterns, the response comprising an index of approved resource patterns;
• and
• receive, from the base station, the activation grant for the resource assignment for the at least one resource pattern, the activation grant comprising the index of approved resource patterns.

• receive, from the base station, a response associated with at least one resource pattern of the plurality of resource patterns, the response comprising an index of approved resource patterns;
• and
• receive, from the base station, the activation grant for the resource assignment for the at least one resource pattern, the activation grant comprising the index of approved resource patterns.
