[SLS-CC] [EXTERNAL] Fw: [SLS] Reconfirmation Review for 230.2-G-1 Next Generation Uplink Next Generation: Proposed Historical designation

Thu Mar 14 16:59:35 UTC 2019

Jon,

inclusion of the material you mention has never been considered for the 
GB, which will include instead performance related material for the codes 
actually
selected for the standard. 
I don't see much value in keeping the NGU book "alive", in my opinion it 
served its purpose. I believe others (Greg included) share this view, but 
if we cannot
achieve a consensus, we'll simply reply to Gian Paolo that the book will 
stay at least for the next 5 years, until the next cycle
Massimo

P.S. The address you are using is not registered in the C&S mailing list 
and this is creating some bouncing issues. I would recommend either to 
register
       it, or to switch to the one that is already there.

Maybe we should discuss this further at the meeting in May?  From what I 
see now, I would prefer not to make 230.2-G-1 silver until we see that 
the rationale and analysis material from Sections 2 and 3, and possibly 
4 and 5, has found a home in the new Green Book.  I don't see the 
material as obsolete, especially things like the figures of merit.
