Introduction
Discussions about 5th Generation Mobile Networks have reached significant intensity in industry, academia and among mobile operators.
There is no common understanding what ‘5G’ means.
All agree that there is no agreement what 5G will be.
A major source of current thinking might be the NGMN 5G White Paper by NGMN Alliance (February 2015)

7. NGMN Alliance thoughts on 5G interface options
July 2015
NGMN Alliance thoughts on 5G interface options
Option 1 has minimal impact to exisiting RATs but limitations to introduce full 5G performance services
Option 2 allows for full evolution of network services for 5G but requires new interfacing with EPC and Fixed/Wi-Fi
Option 3 would be the most comprehensive approach by integrating LTE, 5G and Fixed/Wi-Fi but has manifold implications.
NGMN mandates further research into Option 3 before drawing conclusions.
BTW: Currently it looks like, that initially 5G will be introduced with Option 1 and evolves in a later release into Option 2.

IEEE in 5G discussions
IEEE is present but not a focus topic
5G is mainly about a new 3GPP radio interface and its integration with LTE
Integration models for IEEE mainly based on current 3GPP approaches
S2a/TWAG
LWA
No signs of more revolutionary discussions of integration of IEEE in mobile networks
Option 3 like approaches did generally not find much support in industry

Conclusion
There are enormous efforts behind ‘5G’.
Definition of ‘5G’ is still vague and not settled yet.
It is expected that there will be standardization of a new 3GPP radio interface for ultra dense deployments with commercialization starting around 2020.
IEEE integration into ‘5G’ seems to adopt current 3GPP models for LTE.
