Detected Changes Across Releases
from 3GPP Change RequestsSpecific changes extracted from the „Change history“ tables of 3GPP specifications (1 CRs across 1 releases). Complements the general historical overview above with the evidence-based evolution of this function.
In Release 16, the specification introduced a clarified mapping relationship where, for a PC5 unicast link, a single PC5 QoS Flow identified by a PFI can be associated with more than one V2X service type. This refinement was detailed within the procedures for deriving PC5 QoS parameters and managing the PC5 QoS Context, ensuring that user plane traffic with the same PFI receives consistent forwarding treatment per destination. The update also integrated this logic into the Link Modification Request procedure for adding or removing PC5 QoS Flows on an established unicast link.
