March 2016 doc. : IEEE 802. 11 -16/0346 r 0 Introduction • Pilot location has been decided for 11 ax SU/OFDMA/MU MIMO transmissions • Motions on pilot mapping were passed: – All 802. 11 ax PPDUs use single stream pilots (as defined in 11 ac) in the data section – Single stream pilot (like 11 ac) in HE-LTF shall be used for SU, DL and UL OFDMA as well as DL MU-MIMO transmissions • This presentation discuss pilot sequences – Mainly for data section; LTF has its own pilot values Submission Slide 11 Bin Tian, Qualcomm

March 2016 doc. : IEEE 802. 11 -16/0346 r 0 11 ax Pilot Sequence • Simply reuse 11 ac/11 ah pilot sequences – Depending on RU size, select the corresponding 11 ac/ah pilot sequence – Sequence is tied to the number of pilots in a RU only – RU with same size always has same pilot sequence regardless its location and PPDU BW • Benefit – Reuse the existing sequences so that hardware can be consistent in processing – RUs with the same size can be built and demoded in the same way Submission Slide 12 Bin Tian, Qualcomm

March 2016 doc. : IEEE 802. 11 -16/0346 r 0 Application of Pilot Sequence • Propose to apply 11 ax pilot tone mapping in the same way as 11 ac SSP – Based on defined pilot sequence for certain RU, pilot values are shifted on pilot tones from symbol to symbol • For example: for 52/106 -tone RU with base pilot sequence of {1, 1, 1, -1}, the 1 st data symbol with symbol index 0 will take the values {1, 1, 1, -1} on its 4 pilots, the second symbol has {1, 1, -1, 1}, the third symbol gets {1, -1, 1, 1}, and so on • See detailed formula in Appendix – Overlaying pilot polarity value: same as 11 ac • Applicable to all options Submission Slide 15 Bin Tian, Qualcomm

March 2016 doc. : IEEE 802. 11 -16/0346 r 0 Summary • We proposed base pilot sequences for 11 ax PPDU • Application of 11 ax pilot sequence is proposed to be the same as in 11 ac Submission Slide 16 Bin Tian, Qualcomm
