Dear Joseph,
I drew Venn diagram for DMG, EDMG and non-EDMG again.
DMG STA includes CDMG STA and EDMG STA.
So,
CDMG STA is also DMG STA.
EDMG STA is also DMG STA.
But,
DMG STA is not CDMG STA and EDMG STA.
CDMG STA is not EDMG STA.
EDMG STA is not CDMG STA.
Therefore,
DMG STA can deal with DMG PPDU (or DMG A-PPDU) (Clause 20 PPDU).
CDMG STA can deal with DMG PPDU (or DMG A-PPDU) and CDMG PPDU (Clause 24 PPDU).
EDMG STA can deal with DMG PPDU (or DMG A-PPDU) and EDMG PPDU (or EDMG A-PPDU) (Clause 28 PPDU).
DMG PPDU, CDMG PPDU and EDMG PPDU are unique and mutually exclusive.
Since DMG STA includes two types of STAs, EDMG STA and CDMG STA, the term “non-EDMG” is used to distinguish EDMG STA from other STAs.
I.e., non-EDMG STA includes DMG STA and CDMG STA.
So, non-EDMG does not mean 11ad but 11ad and 11aj.
I agree with these definitions are confusing.
However, based on the above, I would like to know what is inconsistent with what.
Do you still think there is inconsistency in definition of DMG, EDMG and non-EDMG?
Best regards,
Sakamoto

Dear Joseph,
Thank you for your reply.
I understand your point better than before.
The following is described in Clause 4.3.21 of 802.11-2016.
“A DMG STA operates in a DMG BSS and supports transmission and reception of frames that are compliant with PHY specifications as defined in Clause 20.”
Furthermore, the following is described in Clause 4.3.30 of 11ay_D5.0.
“An EDMG STA supports transmission and reception of frames that are compliant with PHY specifications as defined in Clause 20 and Clause 28.”
So, DMG STA deals with DMG PPDUs (Clause 20 PPDUs).
And EDMG STA deals with DMG PPDUs (Clause 20 PPDUs) and EDMG PPDUs (Clause 28 PPDUs).
Do EDMG and DMG style follow HT, VHT and HE style?
Best Regards,
Sakamoto
