q
5G is an immense field of development
m
m
q
Every SDO and innumerable projects and fora work on it
Need to avoid the overlap risk
Need to select and prioritise what can be done effectively
Keep coherence under control
n providing Technical Packages(TPs) by SG13
n TPs: more than the simple sum of different documents
n Currently focus on Slicing and FMC TP
Cooperation is essential
m
m
m
m
Between different Questions in the same WP
With other Study Groups of ITU-T and external entities
Go beyond the usual & formal LS exchange (little real cooperation)
Need to adapt timing and work schedule with other groups
