Abstract

   The Static Context Header Compression (SCHC) specification describes
   a header compression and fragmentation functionalities for LPWAN (Low
   Power Wide Area Networks) technologies.  SCHC was designed to be
   adapted over any of the LPWAN technologies.

   This document describes the use of SCHC over the NB-IoT wireless
   access, and provides elements for an efficient parameterization.
