Hello
Abhi,
How about:
An EBCS AP shall signal buffered EBCS Data frames via the EBCS TIM element (see 9.4.2.x (EBCS TIM element)) instead of the TIM element
[delete: in Beacon frames, since this would prevent EBCS from being used with DMG, for example]. [1005]
[do the tables of Beacon, DMG Beacon, (S1G Beacon) contents need to be updated?]
NOTE—The TIM element has only 1 bit for signaling buffered group addressed frames and
so cannot differentiate between different
streams of traffic [again, traffic streams has a specific meaning in 802.11]. If an EBCS AP were to use the TIM element, an associated non-AP STA that does not subscribe to
any EBCS traffic stream
would wake up for the EBCS traffic streams. This
would cause unnecessary power consumption at the STA. Similarly, using
a TIM element
would cause an unassociated non-AP STA that subscribes to an EBCS traffic
stream to wake up for
any non-EBCS group addressed traffic.
[delete: Usage of EBCS TIM element helps avoid such unnecessary power consumption for both category of STAs, since this is over-egging the pudding].
Thanks,
Mark

Hi Morioka-san,
Thank you for revising the document based on the feedback from the group during the previous call.
May I suggest alternative text for the following paragraph and NOTE page 17?
An EBCS AP shall signal buffered EBCS Data frames via the EBCS TIM element (see 9.4.2.x (EBCS TIM element)) instead of the TIM element in Beacon frames. [1005]
NOTE—The TIM element has only 1 bit for signaling buffered group addressed frames and cannot differentiate between different traffic streams. If an EBCS AP
were to use the TIM element, an associated non-AP STA that does not subscribe to EBCS traffic stream will wake up for the EBCS traffic streams. This will cause unnecessary power consumption at the STA. Similarly, using TIM element will cause an unassociated
non-AP STA that subscribes to an EBCS traffic streams to wake up for the non-EBCS group addressed traffic. Usage of EBCS TIM element helps avoid such unnecessary power consumption for both category of STAs.
Reasoning:
- TIM element signals BUs. Same applies for EBCS TIM element
- The subject in the paragraph and the NOTE is the EBCS AP
- General restructuring for clarity
Regards,
Abhi
