9 Introduction From the SFD [1]: “An UL MU PPDU (MU-MIMO or OFDMA) is sent as an immediate response (IFS TBD) to a Trigger frame (format TBD) sent by the AP. [MAC Motion #3, March 2015]” This presentation discusses the format of the trigger frame S. Merlin (Qualcomm)

10 Trigger Information Format
We propose to define a MAC frame format which carries the trigger info: A new control/extension frame type TBD Legacy header (FC, Duration) allows for NAV setting at any receiver Presence/need for one or two addresses is TBD, and depends on the usage and format of the trigger info The trigger info may include information for one or more recipients and will generally carry certain information that is common for all recipients and certain information that is specific per each recipient FC Duration (A1) A2 2B TBD 6B Common Info field User info 1 … User info n tbd FCS 4B Trigger info fields S. Merlin (Qualcomm)

11 Examples of Trigger Information
The trigger info should include sufficient information to identify the stations transmitting the UL MU PPDUs, and allocating resources for the UL MU PPDUs, and may include other transmission parameters Common info across users Subfields defining the format of the information, if multiple allowed Duration of the immediate UL MU response Indication of the purpose of this trigger Per-user info Identifier of the STA (e.g. AID) Resource allocation description UL MU MIMO: allocated stream(s), UL OFDMA: allocated RU(s) Power control info (TBD) Etc… It is important that the trigger frame source and intended recipient(s) are univocally identified, to avoid responding to an OBSS trigger, or having ambiguity on the responder, which may cause collisions S. Merlin (Qualcomm)

12 Usage As for any other MAC frame, it can be sent in any PHY mode
11a PPDU for legacy compatibility/NAV, HE PPDU for outdoor, etc… Special restrictions may be defined if needed The definition of the trigger as a MAC MPDU enables several possible operation modes, based on existing specs constructs An example of a baseline operation mode is the transmission of a (multi-recipients) trigger frame as a single MPDU in a SU PPDU Another example is the transmission of (single-recipient) trigger frame(s) as single MPDUs in a DL MU PPDU, one per each recipient Another example is that the trigger frame may be included in an A-MPDU S. Merlin (Qualcomm)

13 Straw poll Do you agree to add to the SFD
Month Year Doc Title Straw poll Do you agree to add to the SFD 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 is as in figure Presence of A1 is TBD 60Y/0N/11A S. Merlin (Qualcomm) John Doe, Some Company

14 Motion Move to add to the SFD
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 is as in figure Presence of A1 is TBD 60Y/0N/11A S. Merlin (Qualcomm)
