radio front end circuitry configured to transmit the plurality of SIB messages to a user equipment (UE).
2. The AN of claim 1 , wherein the first communication mode or the second communication mode comprises:
a unicast mode; or
a broadcast mode.
3. The AN of claim 1 , wherein the first configuration or the second configuration comprises:
a sidelink communication using a broadcast operation.
4. The AN of claim 1 , wherein the first configuration or the second configuration comprises:
a sidelink communication using a unicast operation.
5. The AN of claim 1 , wherein the AN comprises a next-generation NodeB (gNB) or a portion thereof.
6. The AN of claim 1 , wherein the delta configuration comprises different congestion-to-priority mapping rules for the common resource to allow for differentiated behavior on the common resource by different UEs.
7. The AN of claim 1 , wherein the common resource comprises a carrier frequency that is applicable to the first communication mode and the second communication mode.
8. A method for vehicle-to-everything (V2X) communication, the method comprising:
