Re: [lp-wan] Options to progress SCHC/Sigfox and new Compound ACK concept

Hello everyone,

+1 for Options 2.

The RFC8724 defines the generic SCHC messages, hence a new draft may define the generic Compound ACK and data model, and then, each profile can define the specific requirements (e.g., if mandatory or not, if some ruleIDs are used for compound ACK, how it is different from the receiver abort, examples, etc). Other new functionalities may have the same path, generic specification with its data model, and implementation specifics in each profile.

Cheers,

Sergio
