12. Trigger dependent Per User Info
Month Year
Doc Title
Introduction
The spec [1] includes the following format for the Trigger frame
The frame format for the Trigger frame is as defined in Figure 9-51a (Trigger frame).
The Per User Info field is defined in Figure 9‑1.
The RU Allocation subfield of the Per User Info field indicates the RU used by the HE trigger-based PPDU of the STA identified by User Identifier subfield. The length and coding of RU Allocation subfield are TBD.
This contribution discusses the RU allocation signaling for each STA carried in per user info field of the Trigger frame.

13. RU Allocation info for each STA

Doc Title
RU Allocation info for each STA
Propose to use 8 bits RU allocation signaling to cover all the different BW cases(e.g. 20/40/80/160MHz).
The 8 bits RU allocation signaling consists of 1 bit for RU location and 7 bits RU indices.
The first bit for RU location indicates the allocated RU is located at the primary or non-primary 80MHz.
The subsequent 7 bits indices indicate 69 possible RU allocation cases based on 80MHz tone plan. The mapping of the 7 bits to the RU allocation is defined in the table below. The last entry means RU allocation with the whole 160/80+80MHz.

15. Summary
In the presentation, we propose to use 8 bits to indicate the RU signaling for each STA, in Per User info field in Trigger frame.

16. Straw Poll Do you support to add to SFD 9.3.1.23 Trigger frame Y/N/A
Use 8 bits to signal the RU allocation for each STA in per user info field of Trigger frame.
The first bit indicates the allocated RU is located in the primary or non-primary 80MHz.
The mapping of the subsequent 7 bits indices to the RU allocation is defined in the table below.
