Hi Dandan,
Please note that 80MHz PR is [1 -1 -1 -1] and 160MHz PR is [1 -1 -1 -1 1 -1 -1 -1] which is constructed by duplicating 80MHz one. So, I think non-contiguous and contiguous cases are unified. From this point of view we came up with unified phase rotation sequences in larger bandwidth. Also, unified one may be beneficial to implementation.
Best regards,
Eunsung

Subject: [STDS-802-11-TGBE] [PHY] Phase Rotation, 11-20/0699r1
Hello Eunsung，
Many thanks for your contribution about document ID 11-20/0699r1.
I think it is better to run the SPs after a comprehensive discussion.
In 11ax, the phase rotation values for pre-HE modulated fields for various CH_BANDWIDTH can be seen from the Table 27-27:
For my understanding, contiguous 160MHz uses 160MHz phase rotation values, while for noncontiguous 160MHz (80+80) each defined 80MHz phase rotation values is applied to each 80MHz.lease correct me if my understanding is not correct.
So for 240/160+80/320/160+160 transmission, it is better to follow the 11ax rule. More specifically, for non-contiguous mode: reusing 160MHz PR values for each 160MHz for 160+160 transmission, and reusing 160MHz and 80MHz PR values for each 160MHz and 80MHz for 160+80MHz transmission. For contiguous 240MHz and 320MHz transmission, the newly defined PR values are needed.
Looking forward to hearing from you.
BR,
Dandan

Hello all,
This is a call for submissions for the upcoming teleconference calls meeting.
Please let me know if you have any items to be added to the agenda by sending me an e-mail with a request using the format below:
- DCN-Presentation Title (Author, Affiliation), Topic
Also please ensure that the presentation is uploaded at least one week prior to the conference call as I will include the links to the presentations in the Submission's list. If the contribution is not uploaded by that time then it may not be included in the list.
PS - There is no need to send an additional request for contributions that are already present in the conf call queue as they will be imported by default to the Back-Logged Submission's List.
Best Regards,
Alfred
