Hi Sanket, 

(#5183

,#10689

)

An EMCCA leading BSSID of an EMCCA set shall be the only AP in its EMCCA set that operates as a Co-TDMA coordinating AP, a polled AP, or a Co-TDMA coordinated AP. 

... 

In a Co-TDMA TXOP, after the polling phase, a Co-TDMA coordinating AP shall set the NAV to expire no later than the start of the transmission of the next scheduled MU-RTS TXS Trigger frame within the same TXOP.

After the polling phase, an AP in the same EMCCA set as the Co-TDMA coordinating AP, not only the Co-TDMA coordinating AP itself, may exchange frames. The sentence should be generalized so that it is not limited to the Co-TDMA coordinating AP.

Similar updates are needed for a Co-TDMA coordinated AP. So, an AP in the same EMCCA set as the Co-TDMA coordinated AP may exchange frames during the allocated phase. 

[Sanket] I understood the ambiguity. I will revise the text in the next revision to clarify that only an EMCCA leading BSSID of an EMCCA set can perform inter-AP frame exchanges, while a non-leading AP can exchange intra-BSS frames.  

(#8356)

The 

bandwidth of the 

PPDU carrying a 

Co-TDMA TB ICF or a Co-TDMA NTB ICF may

 

be larger

 

than

 the overlapping portion

(s)

 of 

the MAPC bandwidths

 of th

e

 Co-TDMA coordinating AP and 

the 

AP(s) polled using the ICF

.

For a Co-TDMA NTB ICF, the ICR’s bandwidth is the same as the bandwidth of the Co-TDMA NTB ICF. If the bandwidth of a Co-TDMA NTB ICF is greater than the bandwidth overlapping with the polled AP, the polled AP would be required to send an ICR using a bandwidth that is not supported by the MAPC bandwidth of the polled AP? Could you clarify which scenario you are considering? 

[Sanket] No, the polled AP is not required to send an ICR using a bandwidth that is not supported by its MAPC bandwidth. The UL BW Extension field, together with the UL BW field in the Common Info field of the BSRP NTB Trigger frame, indicates an ICR bandwidth that does not exceed the overlapping portion of the MAPC bandwidths of the Co-TDMA coordinating AP and the polled AP.

Thanks, 

Yongho

Hi Alfred,

I have uploaded the CR document 11-26/1098r0 to the server. The document resolves 40 CIDs, including the Joint CIDs assigned to me.

Co‑TDMA TTT: Please review the document and let me know your feedback, if any.

Best,

Sanket Kalamkar
