Dear authors, all,

What I am struggling to understand from the draft is: where exactly are all the other details (e.g., physical level, link level) specified? Is it the reference "ICAO SARPs Annex 10 Vol. III from 2018"? I think less likely since ICAO to my understanding does not specify physical layer aspects? Are there publicly accessible specs? There is a brief section on Physical layer etc. in the draft but it should cite this reference. Without those, I am struggling to understand the whole picture; any help in this regard would be greatly appreciated!

Thanks,
Waqar.

> Abstract:
>    This document provides an overview of the architecture of the L-band
>    Digital Aeronautical Communications System (LDACS), which provides a
>    secure, scalable and spectrum efficient terrestrial data link for
>    civil aviation.  LDACS is a scheduled, reliable multi-application
>    cellular broadband system with support for IPv6.  LDACS SHALL provide
>    a data link for IP network-based aircraft guidance.  High reliability
>    and availability for IP connectivity over LDACS are therefore
>    essential.
