3.1 Terms

For the purposes of the present document, the terms given in 3GPP TR 21.905 [1] and the following apply. A term defined in the present document takes precedence over the definition of the same term, if any, in 3GPP TR 21.905 [1].

E-UTRA-PC5: PC5 reference point over E-UTRA. The term E-UTRA-PC5 used in the present document corresponds to the term LTE PC5 defined in 3GPP TS 23.287 [3].

NR-PC5: PC5 reference point over NR. The term NR-PC5 used in the present document corresponds to the term NR PC5 defined in 3GPP TS 23.287 [3].

PC5 QoS flow context: A context which includes a set of V2X service identifiers, a PQFI value and a set of PC5 QoS parameters.

PC5 QoS rule: A rule which includes a PC5 QoS rule identifier, a PQFI value, a precedence value and optionally a set of packet filters. The PC5 QoS rule is associated with a PC5 QoS flow context.

V2X service identifier: an identifier of a V2X service, e.g. PSID, ITS-AID, or AID of the V2X application. The term V2X service identifier used in the present document corresponds to the term V2X service type defined in 3GPP TS 23.287 [3].
