Hi Eunsung,
Thanks your work. I have some comments for SP1 as follows.
1)
for transmit beam establishment, containing multiple sounding signal or TRN subfiles within one PPDU may raise the issue that how to configure the
transmit beam for preamble part. It would probably reduce the beam detect performance.
2)
For sounding signal or TRN subfield, we had better check whether put “e.g.,
LTF” in the SP Now, as we know that there may exist two different LTF types, and STF can also be used for beam measure. BR Jiqing Ni OPPO 发件人: Eunsung Park <esung.park@xxxxxxx>
Hi Qinghua, Thanks very much for the feedback. Regarding SP2-3 (25/1535r1 Discussion on BFT Types for 11bq), I got
your point. Then, how about changing the text as below?
I will defer SP2 (25/1914r1 PPDU for Sector Level Sweep in 11bq) and let’s
have a further discussion. Best regards, Eunsung From: Li, Qinghua <qinghua.li@xxxxxxxxx>
Hi Eunsung, Thanks for the SPs and related contributions. I have some comments below. I would like to ask for deferrals of two SPs and hope to have more discussions. SP2-3 (25/1535r1 Discussion on BFT Types for 11bq)
[QL] Suggest to defer the SP. The sounding signal for evaluating beams/sectors has not been evaluated and discussed.
The sounding PPDU is just the carrier of the sounding signal(s). It is feasible that one PPDU with multiple sounding signals for multiple beams/sectors is defined for 11bq. It is desired to have more time for discussions.
SP2 (25/1914r1 PPDU for Sector Level Sweep in 11bq)
[QL] Suggest to defer the SP. The best beam/sector that is selected from 320MHz and 640MHz sounding for the same channel may be different. It would be helpful to have some
evaluations showing the sector/beam selection is accurate enough using 320 MHz for 640 MHz.
Thanks, Qinghua

Hi all, I am supposed to run four SPs on Thursday PM1 as follows. They are from my previous contributions regarding beam training (25/1535r1)
and NDP (25/1914r1). Before running them I would like to get some feedback. I would be grateful if you could review them and share your thoughts. Any comments and questions are welcome. Best regards, Eunsung SP2-3 (25/1535r1 Discussion on BFT Types for 11bq)
SP5-1 (25/1535r1 Discussion on BFT Types for 11bq)
SP1 (25/1914r1 PPDU for Sector Level Sweep in 11bq)
SP2 (25/1914r1 PPDU for Sector Level Sweep in 11bq)
