Submission

Interpretation Request #1

• Introduction:• Service Providers use Multi-SSID many ways:

– extra SSID for particular use-case, device-class, WEP...– very important for non-enterprise (hotspots, homes...)

• But…There are interop issues– Beacon timing

• Some devices cannot cope with a variable or very-short beacon interval– no problems if 50mSec apart, BUT t=SIF gives problems with some devices !

• Needs defining for multi-SSIDs– All clients need to cope with such timing– Spacing beacons by just SIFS/DIFS

• Question:• If an AP device is generating multiple BSSID signals what is the

proper spacing between those SSIDs?


July 2008


Slide 25

doc.: IEEE 802.11-08/0928r1

Submission

Interpretation Request Response #1• The IEEE 802.11-2007 only defines one MAC/PHY pair as a

STA. When a product virtualizes multiple STAs within the same physical device, the interaction of the virtual STAs are currently outside the scope of the standard, however the use of multiple BSSID/SSID functionality is currently being defined.

• The commenter (and others interested) are invited to come and participate with the 802.11 WG.

• Moved to approve the Interpretation Request Response #1: – May 2008: Moved: Stephen McCann, 2nd David Hunter -

• Passed: 5-0-0– July 2008: Affirmed – David Hunter – 2nd Jeremy deVries --

• Passed 3-0-1


July 2008


Slide 26

doc.: IEEE 802.11-08/0928r1

Submission


• Section 7.3.1.17 of [1] says that the Max SP Length subfield of the QoS Info field is reserved when all four U-APSD flags are set to 0. Section 7.1.1 of [1] says that reserved fields and subfields are set to 0 upon transmission and are ignored upon reception.

• If a non-AP STA sets all four U-APSD flags to 0 in the QoS Info field in the QoS Capability IE in the Association Request, and then uses an ADDTS Request to set up a delivered-enabled TS (and also sets up a trigger-enabled TS -- perhaps the same TS), how many buffered MSDUs and MMPDUs may the AP deliver to this non-AP STA during an SP triggered by this non-AP STA?


July 2008


Slide 27

doc.: IEEE 802.11-08/0928r1

Submission

Interpretation Response #2

• The standard does not specify, when the bits are set to 0, a maximum limit to how many MSDU or MMPDUs are buffered by an AP. Therefore the maximum number would be AP implementation dependent value and would be dependent on the amount of traffic buffered at the AP (See table 7-25 bit 5-6). When Bit 5 and 6 are not set to 0, then a limit is prescribed.

• Moved to accept response #2: – David Hunter; 2nd Roger Durand … – 3-0-2 passes


July 2008


Slide 28

doc.: IEEE 802.11-08/0928r1

Submission

Interpretation Request #3• An interpretation is requested on the following:• Section 7.3.2.20 of [1] says that the Minimum PHY Rate field of

the TSPEC IE is “the desired minimum PHY rate to use for this TS, in bits per second, that is required for transport of the MSDUs belonging to the TS in this TSPEC.”

• What are the exact semantics of this field?• Does this need to correspond to an operational rate of the AP

which the non-AP STA can transmit at, for a TS with an uplink component (vice-versa for a TS with a downlink component)? [*]

• If not, must it be a rate supported by the PHY being used (though perhaps not a rate supported by the non-AP STA and/or AP)?

• If not, must it be less than or equal to the highest rate supported by the PHY being used? Or the highest rate supported by the non-AP STA and AP?

• And if the answer to question marked with [*] is no, then how is K.2.2 to be used?


July 2008


Slide 29

doc.: IEEE 802.11-08/0928r1

Submission

Interpretation Request #3-- Example

• An example may help. Say we're using 802.11a, the AP supports 6, 12, 24 and 48 Mbps, and the STA supports 6, 9, 12 and 24 Mbps (here "supports" means both tx and rx). Which of the following values would be valid values in the Minimum PHY Rate field for an uplink TSPEC, and for those values, what value would be used for to compute the MPDUExchangeTime in section K.2.2 of [1]?

• 24 000 000 (supported by both STAs)• 9 000 000 (not supported by AP)• 48 000 000 (not supported by non-AP STA)• 18 000 000 (valid .a rate, but not supported by either STA)• 36 000 000 (valid .a rate, but not supported by either STA and higher than non-AP STA's

highest rate)• 27 000 000 (valid .a rate, but only in "half-clocked" operation)• 54 000 000 (highest rate on .a; not supported by either STA)• 1 111 111 111 (not a valid rate for any PHY; higher than highest rate on any PHY)• 111 111 111 (not a valid rate for any PHY; higher than highest rate on .a)• 11 111 111 (not a valid rate for any PHY, but in .a rate range)• 1 111 111 (not a valid rate for any PHY; lower than lowest rate on .a)• 111 111 (not a valid rate for any PHY; lower than lowest rate on any PHY)• 11 000 000 (not a valid .a rate, but valid .b rate and in .a rate range)• 1 000 000 (not a valid .a rate and not in .a rate range, but valid .b rate)

Slide 30

doc.: IEEE 802.11-08/0928r1

Submission

Response for Interpretation Request #3

• In clause 7.3.2.30, the Minimum PHY Rate field definition: – The Minimum PHY Rate field is 4 octets long and contains an

unsigned integer that specifies the desired minimum PHY rate to use for this TS, in bits per second, that is required for transport of the MSDUs belonging to the TS in this TSPEC21.• Footnote 21: This rate information is intended to ensure that the

TSPEC parameter values resulting from an admission control negotiation are sufficient to provide the required throughput for the TS. In a typical implementation, a TS is admitted only if the defined traffic volume can be accommodated at the specified rate within an amount of WM occupancy time that the admissions control entity is willing to allocate to this TS.

Slide 31

Submission

Response for Interpretation Request #3 (cont)

• The standard does not require the use any of the Operational Rates for the value of the Minimum PHY Rate.

• K2.2 is part of an Informative Annex, and is provided to assist implementers, but it does not specify required functionality.

• Move to accept the response: – Move: Roger Durand; 2nd Jeremy deVries– 3-0-1 passes

Participants, Patents, and Duty to Inform

All participants in this meeting have certain obligations under the IEEE-SA Patent Policy. Participants:

– “Shall inform the IEEE (or cause the IEEE to be informed)” of the identity of each “holder of any potential Essential Patent Claims of which they are personally aware” if the claims are owned or controlled by the participant or the entity the participant is from, employed by, or otherwise represents

• “Personal awareness” means that the participant “is personally aware that the holder may have a potential Essential Patent Claim,” even if the participant is not personally aware of the specific patents or patent claims

– “Should inform the IEEE (or cause the IEEE to be informed)” of the identity of “any other holders of such potential Essential Patent Claims” (that is, third parties that are not affiliated with the participant, with the participant’s employer, or with anyone else that the participant is from or otherwise represents)

– The above does not apply if the patent claim is already the subject of an Accepted Letter of Assurance that applies to the proposed standard(s) under consideration by this group

Quoted text excerpted from IEEE-SA Standards Board Bylaws subclause 6.2• Early identification of holders of potential Essential Patent Claims is strongly encouraged• No duty to perform a patent search

• Introduction:• Service Providers use Multi-SSID many ways:

– extra SSID for particular use-case, device-class, WEP...– very important for non-enterprise (hotspots, homes...)

• But…There are interop issues– Beacon timing

• Some devices cannot cope with a variable or very-short beacon interval– no problems if 50mSec apart, BUT t=SIF gives problems with some devices !

• Needs defining for multi-SSIDs– All clients need to cope with such timing– Spacing beacons by just SIFS/DIFS

• Question:• If an AP device is generating multiple BSSID signals what is the

proper spacing between those SSIDs?

Interpretation #1 history

• In May, we proposed a resolution.• Afterward, it was found that the request had not come

by normal channels. • I have talked to the SASB secretary, and now the

request is ok.• I propose that we use the response from the May

Interim

Submission

Interpretation Request Response #1• The IEEE 802.11-2007 only defines one MAC/PHY

pair as a STA. When a product virtualizes multiple STAs within the same physical device, the interaction of the virtual STAs are currently outside the scope of the standard, however the use of multiple BSSID/SSID functionality is currently being defined.

• The commenter (and others interested) are invited to come and participate with the 802.11 WG.

• Moved to approve the Interpretation Request Response #1: – Moved: Stephen McCann, 2nd David Hunter - Passed: 5-0-0– From May 2008 Meeting –

• Affirmed – David Hunter – 2nd Jeremy deVries -- Passed 3-0-1

Submission


• Section 7.3.1.17 of [1] says that the Max SP Length subfield of the QoS Info field is reserved when all four U-APSD flags are set to 0. Section 7.1.1 of [1] says that reserved fields and subfields are set to 0 upon transmission and are ignored upon reception.

• If a non-AP STA sets all four U-APSD flags to 0 in the QoS Info field in the QoS Capability IE in the Association Request, and then uses an ADDTS Request to set up a delivered-enabled TS (and also sets up a trigger-enabled TS -- perhaps the same TS), how many buffered MSDUs and MMPDUs may the AP deliver to this non-AP STA during an SP triggered by this non-AP STA?

Submission

Interpretation Response #2

• The standard does not specify, when the bits are set to 0, a maximum limit to how many MSDU or MMPDUs are buffered by an AP. Therefore the maximum number would be AP implementation dependent value and would be dependent on the amount of traffic buffered at the AP (See table 7-25 bit 5-6). When Bit 5 and 6 are not set to 0, then a limit is prescribed.

• Moved to accept response #2: – David Hunter; 2nd Roger Durand … – 3-0-2 passes

Slide 52

Submission

Interpretation Request #3• An interpretation is requested on the following:• Section 7.3.2.20 of [1] says that the Minimum PHY Rate field of

the TSPEC IE is “the desired minimum PHY rate to use for this TS, in bits per second, that is required for transport of the MSDUs belonging to the TS in this TSPEC.”

• What are the exact semantics of this field?• Does this need to correspond to an operational rate of the AP

which the non-AP STA can transmit at, for a TS with an uplink component (vice-versa for a TS with a downlink component)? [*]

• If not, must it be a rate supported by the PHY being used (though perhaps not a rate supported by the non-AP STA and/or AP)?

• If not, must it be less than or equal to the highest rate supported by the PHY being used? Or the highest rate supported by the non-AP STA and AP?

• And if the answer to question marked with [*] is no, then how is K.2.2 to be used?

Interpretation Request #3-- Example

• An example may help. Say we're using 802.11a, the AP supports 6, 12, 24 and 48 Mbps, and the STA supports 6, 9, 12 and 24 Mbps (here "supports" means both tx and rx). Which of the following values would be valid values in the Minimum PHY Rate field for an uplink TSPEC, and for those values, what value would be used for to compute the MPDUExchangeTime in section K.2.2 of [1]?

• 24 000 000 (supported by both STAs)• 9 000 000 (not supported by AP)• 48 000 000 (not supported by non-AP STA)• 18 000 000 (valid .a rate, but not supported by either STA)• 36 000 000 (valid .a rate, but not supported by either STA and higher than non-AP STA's

highest rate)• 27 000 000 (valid .a rate, but only in "half-clocked" operation)• 54 000 000 (highest rate on .a; not supported by either STA)• 1 111 111 111 (not a valid rate for any PHY; higher than highest rate on any PHY)• 111 111 111 (not a valid rate for any PHY; higher than highest rate on .a)• 11 111 111 (not a valid rate for any PHY, but in .a rate range)• 1 111 111 (not a valid rate for any PHY; lower than lowest rate on .a)• 111 111 (not a valid rate for any PHY; lower than lowest rate on any PHY)• 11 000 000 (not a valid .a rate, but valid .b rate and in .a rate range)• 1 000 000 (not a valid .a rate and not in .a rate range, but valid .b rate)

Submission

Response for Interpretation Request #3

• In clause 7.3.2.30, the Minimum PHY Rate field definition: – The Minimum PHY Rate field is 4 octets long and contains an

unsigned integer that specifies the desired minimum PHY rate to use for this TS, in bits per second, that is required for transport of the MSDUs belonging to the TS in this TSPEC21.• Footnote 21: This rate information is intended to ensure that the

TSPEC parameter values resulting from an admission control negotiation are sufficient to provide the required throughput for the TS. In a typical implementation, a TS is admitted only if the defined traffic volume can be accommodated at the specified rate within an amount of WM occupancy time that the admissions control entity is willing to allocate to this TS.

Submission

Response for Interpretation Request #3 (cont)

• The standard does not require the use any of the Operational Rates for the value of the Minimum PHY Rate.

• K2.2 is part of an Informative Annex, and is provided to assist implementers, but it does not specify required functionality.

• Move to accept the response: – Move: Roger Durand; 2nd Jeremy deVries– 3-0-1 passes
