This assumption has limitations on the location of NR UL carriers, supported UE channel bandwidths and so on. During the Rel-18 discussion of how to specify PC2 requirements in band n28, it is a desire from industry to evolve duplexer implementation and RF architecture for band n28.

The solutions were based on N3IWF, which was responsible for handling the interoperability between non-3GPP networks and the 5G core network. However, with the widespread commercial deployment of VoWiFi, ePDG has become the primary way for addressing non-3GPP access. ePDG was not supported for R16\/R17 ATSSS, but was introduced in the Rel-18 ATSSS WI, which will better align with the current network deployments.
