10. Introduction
The SFD [1] includes the following format for the Trigger frame
The spec shall define a new control frame format that carries sufficient information to identify the STAs transmitting the UL MU PPDUs and allocating resources for the UL MU PPDUs. The format of the new frame is given in Figure 11. The presence of A1 is TBD. [MAC Motion 19, July 16, 2015, see [70]
This contribution discusses the signaling to be carried by the trigger frame, especially the information that may be included optionally according to the trigger response type
LG Electronics

11. Recap [2]
The contribution [2] provides which parameters are essentially included in the Trigger frame
In Common Info field
UL MU PPDU length
Info bits content of the SIG-A
CP + HE LTF type
Allowed response type / trigger type
In Per-User Info field content
MCS
Coding type
RU allocation information
SS allocation
DCM
User identifier field
Kiseon Ryu et al. (LG)

12. Allowed response type / Trigger type
Trigger frame can trigger the various type of UL MU frames
MU-BAR frame triggers UL MU BA transmissions
Trigger frame in DL CSI feedback procedure triggers UL MU beamforming feedback frames
Trigger frame can be used to poll multiple STAs for buffer status report
MU-RTS frame solicits simultaneous CTSs frame from multiple STAs
Trigger frame for random access allows STAs to access the medium randomly using OFDMA transmission
We discuss the parameters to be optionally included in the Trigger frame according to the trigger type
Kiseon Ryu et al. (LG)

13. Optional type-specific Info
MU-BAR
BAR Control field is included as a type-specific Per-User Info parameter
BAR Information field is included as a type-specific Per-User Info parameter
Trigger frame for random access
Indicator of cascaded sequence of Trigger frames is included as a type-specific parameter
TBD parameter may be included as a type-specific parameter
Etc.

15. Straw poll 1 Do you agree to add to the spec framework document?
The spec shall define optional type-specific Common Info and optional type-specific Per User Info of Trigger frame. The locations of type-specific Common Info and type-specific Per User Info are TBD. Y: N:
