Introduction
• The following text was included in 11ax 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– The amendment shall define a mechanism for multiplexing DL acknowledgments sent in
response to UL MU Transmissions
• In this presentation we defines the rules for UL OFDMA transmission

Transmission Sequence of SU TXOP
• In SU frame exchange, the frame exchange is eliciting MPDU/A-MPDU and single responding MPDU.– One TXOP responder acknowledges the received MPDU/A-MPDU.
• When the TXOP holder receives the responding frame of the eliciting frame, the frame exchange is successful.‒ When the following frame exchange in the TXOP fails, the AP can do PIFS recovery
without backoff.

UL OFDMA Transmission Sequence: UL OFDMA PPDU• For a UL OFDMA transmission, the frame exchange sequence defined in 11ax SFD [3] is
Trigger frame, UL OFDMA PPDU, DL acknowledge.– Trigger frame indicates to a set of STAs to transmit UL OFDMA PPDUs as an immediate response
to the Trigger frame, the subchannels of the STAs for UL transmission etc.• We propose that the reception of at least one of the UL MPDU sent as immediate response to
a Trigger Frame indicates a successful transmission of the trigger frame.– The AP can decide the following behavior in the TXOP based on the correctly received successful
UL OFDMA MPDU/A-MPDU, e.g. continue the OFDMA transmission, switch to SU frame exchange.
– When the following frame exchange in the TXOP fails, the AP can do PIFS recovery without backoff.

Straw Poll 1Do you agree to add the following to the SFD: • UL OFDMA MPDU/A-MPDU is the acknowledgement of the trigger frame.
– When the AP receives MPDU correctly from at least one STA indicated by trigger frame, the frame exchange initiated by the trigger frame is successful
