Discussions
In current Spec Framework, the two 2MHz preambles are named as
“SU Preamble” and “MU Preamble”.
Issues with the names based on functionalities:
Current “MU preamble” is allowed to transmit both MU and SU packets (as in 11ac).
We propose to rename the two preambles using neutral names (e.g. based on preamble structures itself) instead of based on functionalities.
Propose to rename as “short preamble” and “long preamble”—similar to 11b.
Also need to rename some subfields in the long preamble
