Re: [STDS-802-11-TGBE] TGbe Teleconference [08/29/2019]: Reminder

Hi Liuming,


Thank you for the presentation (11-19/0951r0).


I have a couple of questions:

  1. On slide #6, could you please elaborate on how you differentiate between RTA and non-RTA traffic? As you may know traffic class information is usually lost when a packet traverses thru a legacy routers along the way.
  2. On slide #7, the CAP period are set aside to aid RTA transmissions. However, your slide mentions that non-RTA traffic is allowed during these times along with non-CAP periods. Seems like non-RTA traffic will benefit in your scheme. Shouldn’t you disallow non-real-time traffic during CAP periods? Also how do you prevent OBSS STAs from occupying the medium during CAP periods?

Hi Liuming,


Thanks for the 11019/951 presentation! I have the following clarification question:


The proposal focuses on real-time applications with high throughput and “worst case latency” requirements. Based on Slide 7, non-RTA traffic has channel access opportunities in CSMA TXOPs and CAPs. And, RTA traffic use scheduled access in CAPs.  It is a bit unclear to me how the proposed solution is improving the worst case latency performance.

Hi Liuming,

                Thanks for your presentation(0951r0–Discussion on Multi-band/channel Access), It is interesting to use multi-links to help RTA application. However, I have two questions for your design, would you please to clarify?


  1. In the below figure, when this AP setup CAP in band 1, the OBSS will not able to setup RTA application anymore, because the duration of CAP may larger than the latency requirement of RTA. Am I understand correctly?
  2. When there are legacy OBSS in band 1, how AP can setup CAP?
