[STDS-802-11] Changes proposed in TGmf w.r.t. 11mf/D1.0

--- This message came from the IEEE 802.11 Working Group Reflector ---

Please be hereby notified of the following proposed resolutions in TGmf:

 

CID 399
11.40
3174.48 

"An AP shall not include the Operating Mode Notification element in Beacon, Probe Response, Association Response, and Reassociation Response frames when not changing the maximum number of spatial streams the AP is able to receive."

There is no justification for this restriction.  If the AP just wants to change the BSS width, it will then only be able to use (E)CSA frames, which is less robust than also announcing in beacons

Delete the cited text

Proposed resolution:
ACCEPTED

CID 415
10.25.2
2304.34 

"Is not greater than 64 if the sender or receiver of the ADDBA Response frame is a non-HE STA or if
the STAs that establish the block ack agreement are HT STAs or DMG STAs that are not EDMG STAs.(11ax)(11ay)"
-- a DMG STA is probably a non-HE STA, and HT STAs are non-HE STAs

At least delete the "HT STAs", but it's weird to first talk of "if sender or receier is non-HE" then "STAs that establish BA agreement"

Proposed resolution:
REVISED
At 2304.33,

third bullet change to "... are HE STAs but are not both EHT STAs"

second bullet change to "... frame is not an HE STA and is not an EDMG STA"

last bullet change "if the STAs ... are" to "if the sender and receiver of the ADDBA Response frame are"

CID 460
9.2.4.7.3

707.9

"UL MU Data frame" confuses PPDUs and MPDUs

 

At 707.9 change "Trigger based UL MU Data frame transmissions" to "Transmissions of TB PPDUs containing one or more Data frames,"  At 4441.49 change "only UL MU Data frame transmission is suspended" to "only the transmission of TB PPDUs containing one or more Data frames is suspended"

 

Proposed resolution:
ACCEPTED

CID 520

11.43

3188.17

 

"When operating in frequency bands below 6 GHz, the Beacon RSSI has an accuracy of +/- 5 dB (95% confidence interval) within the specified dynamic range of the receiver." -- the required accuracy for 6G+ is missing

Change "When operating in frequency bands below 6 GHz, the" to "The"

Proposed resolution:
ACCEPTED

CID 559

11

1943

In various frames it is stated that "The VHT Capabilities element is present in the 5 GHz band when
dot11VHTOptionImplemented is true", but if a TDLS STA supports channel switch, then it will need the VHT Capabilities element if switching to the 5G band

 

Add this element to TDLS Channel Switch Request/Response

 

REVISED

Add a new row to the end of Table 9-575 (at 1944.1):

Order: "12"

Information: "VHT Capabilities"

Notes: "The VHT Capabilities element is present when switching to the 5 GHz band if dot11VHTOptionImplemented is true."

 

Discussion can take place here, or on the TGm reflector, or by direct email.

 

Thanks,

 

Mark
