What changed in its specifications
The latest release-to-release comparison of specifications that define PFI. Each summary describes the whole specification, not only this term.
Rel-18 adds NR PC5 carrier aggregation and NR eTx Profiles for V2X services, along with per-flow radio frequency information passed from the V2X layer to the AS layer. It also adds MBS support for V2X, including message reception via MBS and MBS session announcement.
Full comparison in TS 23.287 →Rel-19 adds multi-hop NR sidelink relaying through Intermediate UE-to-Network Relay entities, with discovery, QoS and link handling clauses. It also adds path switching between direct and indirect paths via Layer-2 UE-to-Network Relay, and ProSe support for SNPNs and CAG use in PNI-NPNs.
