May 2015 802.11-15/0615r1 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 Acknowledge frame Trigger frame AP AP STA STA1 1 UL MU PPDU Spatial domain Frequency/ STA STA2 2 UL MU PPDU STA STA3 3 UL MU PPDU STA STA4 4 UL MU PPDU In this presentation we defines the rules for UL OFDMA transmission Submission Slide 9 Liwen Chu et al. (Marvell)
May 2015 UL OFDMA Transmission Sequence: UL OFDMA PPDU 802.11-15/0615r1 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 OFDMA MPDU/A-MPDU sent as immediate response to a Trigger Frame indicates a successful transmission of the trigger frame Moreover, An AP shall not allocate UL subchannel in any 20MHz channel that is not occupied by the Trigger frame. In each 20MHz channel occupied by the Trigger frame, there is at least one allocated subchannel for UL transmission. Multi-STABA Multi- STA BA Trigger STA3 A-MPDU to AP 40MHz STA2 A-MPDU to AP STA1 A-MPDU to AP Multi- STA BA Trigger Backoff STA0 A-MPDU to AP UL DL TXOP Primary 20MHz channel.

May 2015 802.11-15/0615r1 Straw Poll 1 Do you agree to add the following to the SFD: UL OFDMA MPDU/A-MPDU is the acknowledge of the trigger frame. When the AP receives UL MPDU/A-MPDU correctly from at least one STA indicated by trigger frame, the frame exchange initiated by the trigger frame is successful An AP shall not allocate UL subchannel in any 20MHz channel that is not occupied by the Trigger frame. In each 20MHz channel occupied by the Trigger frame, there is at least one allocated subchannel Submission Slide 12 Liwen Chu et al. (Marvell)
