4.1 General concept p. 10

There are two modes of operation for V2X communication, namely V2X communication over PC5 reference point and V2X communication over Uu reference point. These two operation modes may be used by a UE independently for transmission and reception.

V2X communications over PC5 reference point are supported by LTE and/or NR.

V2X communications over Uu reference point are supported by E-UTRA connected to 5GC and/or NR connected to 5GC:

For E-UTRA connected to 5GC, V2X communication over Uu reference point is only unicast.
For NR connected to 5GC, V2X communication over Uu reference point can be unicast and/or multicast/broadcast as defined in TS 23.247.

An RSU is not an architectural entity, but an implementation option. This is achieved by collocating a V2X application logic/server with some entities of the 3GPP system, as shown in examples in Annex B.
