Hi Dibakar,

 

I have same view with Yunbo. There are too many issues to be discussed for MU cases. Let keep them to R2 discussion.

It is good to keep TF with unified design now from STA implementation point of view.

Hi Dibakar,

 

Thanks for the offline discussion about the signaling of time allocation, you already know my opinions. Here I just want to repeat it here to the group for others to consider.

 

I prefer Option 2 (in common info), the reasons are below:

 

1)      Signaling in common info aligned with current TF design, UL Length in basic TF servers a very similar function as time allocation here;

2)      Signaling in common info can support well for allocation for single STA (what Trigger SU mechanism currently supports), and can also support allocation to multiple STAs (will be discussed in R2), as long as multiple STA are allocated for same time duration (e.g. Co-SR, Co-OFDMA);

3)      What opt 2 can not support is the scenario that allocate time to multiple STAs and each STA has different time duration. I think it is not a simple extension for current Trigger SU. It may affect a lot for signaling and procedure, not only the time allocation. I think we need discuss the use case and procedure first before we go into the frame format design;

4)      In R2, if the group agree to allocate time for multiple STAs, and each STA allows to has different time duration. There are still a lot of reserved field to carry the signaling or add a new MU-RTS TXS TF mode, in that case we can have a brand new frame format design for it. So there is no concern that opt2 will close the door for future extension.

 

 

Regards,

Yunbo

Hi all,

 

I uploaded document 268r4 related to the channel access for triggered SU.

 

Regarding the signaling of the time allocation, I received two opposite offline feedback.

Option 1: signal the information in User Info. This will allow an easy extension in R2 in case we want to extend this signaling for other purposes such as Multi-user TXOP Sharing or C-TDMA.

Option 2: signal the information in Common Info, in particular the UL Length field. This keeps it aligned with baseline design of the TF wrt usage of UL Length field. However, it makes it more convoluted to extend the signaling for any multi-user cases in future because 1. It changes the signaling location for same functionality (i.e., allocated time) based on whether its for SU or MU and 2. The number of available reserved bits in User Info is much smaller than one in Common Info which could result in different granularity of time allocation in the SU and MU variants.

 

Personally, I think Option 1 is more forward-looking and will simplify the design for any multi-user TXOP sharing procedure while not adding  any complexity for the SU cases in r1.  However, the current document assumes Option 2.

 

Please let me know if you have a preference on Option 1 or Option 2 and if you have any suggestions on how to resolve this issue.

 

 

Regards,

Dibakar

Hi all,

 

I uploaded a new revision of 268r2  (Triggered SU channel access) to mentor. Please review.

 

I tentatively added as co-author the members who contributed to the spec text. Please let me know offline if you don’t want your name to be included and I can remove it in the next revision.

 

Regards,

Dibakar
