March 2016 doc.: IEEE 802.11-15/1354r2 Introduction Revision 1 of this document summarized and organized SIG fields in tables for SU, MU and trigger based UL. In this revision, revision 2, we add several more fields, namely: Doppler STBC for MU Spatial reuse fields for trigger based UL Submission Slide 10 Ron Porat, Broadcom
March 2016 doc.: IEEE 802.11-15/1354r2 SIG-A Table for the SU Preamble Format Brief explanation Field #Bits Format indication: distinguish between SU and trigger based UL [1] DL/UL 1 Format Indication 1 BSS Color 6 BSS Color: Base station identifier [2] Spatial Reuse TBD Spatial reuse: Exact bits TBD e.g. indicaation of CCA Level, Interference Level accepted, TX Power TXOP duration TBD Bandwidth 2 MCS 4 TXOP Duration: [1] CP+LTF size 3 Coding CP + LTF Size: [3] 2 Nsts 3 DCM: Dual carrier modulation indication [2] STBC 1 TxBF 1 Packet extension: a -factor field of 2 bits and 1 disambiguation bit [2] DCM 1 Packet Extension 3 Beam change: Indicate precoder change/no change between L-LTF and HE-LTF [4] Beam change 1 CRC 4 Tail 6 Submission Slide 11 Ron Porat, Broadcom
March 2016 doc.: IEEE 802.11-15/1354r2 SIG-A Table for the MU Preamble Format Brief explanation Field #Bits DL/UL 1 Refer to previous slide for explanation on bits similar to the SU format BSS Color 6 Spatial Reuse TBD SIGB Modulation: [5] TXOP duration TBD Bandwidth >=2 #SIGB symbols: <= 16 (4 bits) support about 16 users using MCS0 per BCC SIGB MCS 3 SIGB DCM 1 Compression mode: Differentiates full bandwidth MU-MIMO from OFDMA MU PPDU [6]. More compression modes TBD SIGB # of symbols 4 SIGB Compression Mode >=1 #LTFs: Up to 8 LTFs possible 3 bits # of HE-LTF 3 LDPC extra symbol: [2] CP+LTF size 3 LDPC extra symbol 1 BW field may accommodate more than in SU case to take advantage of OFDMA Packet Extension 3 CRC 4 Tail 6 Submission Slide 12 Ron Porat, Broadcom
March 2016 doc.: IEEE 802.11-15/1354r2 SIG-A Table for the Trigger based UL Preamble Format Field #Bits Brief explanation Format 1 Format indication: distinguish between SU and UL MU PPDUs [1] BSS Color 6 TXOP TBD BSS Color: Base station identifier [2] Spatial reuse TBD Spatial reuse: Exact bits TBD but examples given in Appendix CCA Level, Interference Level, TX Power Bandwidth TBD CRC 4 TXOP Duration: [1] Tail 6 Submission Slide 13 Ron Porat, Broadcom
March 2016 doc.: IEEE 802.11-15/1354r2 Doppler Bit Similar to 11ah, 11ax is also targeting outdoor. We propose to add one bit to indicate a PPDU with enhanced immunity to Doppler. The exact design is TBD but could use e.g. the travelling pilots concept as defined in 11ah with appropriate modifications for 11ax. For SU the natural signaling place is SIGA whereas for MU signaling could take place in SIGA or SIGB Also, in order to support the same feature in trigger based UL MU we propose to add a Doppler bit to the trigger frame Submission Slide 14 Ron Porat, Broadcom
March 2016 doc.: IEEE 802.11-15/1354r2 STBC Bit STBC bit currently included in the SIGA for SU but not in SIGA or SIGB for MU. As previously motioned before, in a MU PPDU all RUs are either STBC or not STBC, hence it makes sense to add this bit in SIGA of the MU PPDU as well Submission Slide 15 Ron Porat, Broadcom
March 2016 doc.: IEEE 802.11-15/1354r2 Spatial Reuse in Trigger Based UL Spatial Reuse field has been included in SIGA for all preamble formats. Exact bits TBD e.g. indication of CCA Level, Interference Level accepted. Recall that in trigger based UL all information in SIGA is copied from the trigger frame, is identical for all STA, and is fully controlled by the AP who is also the recipient of the UL MU packet. Hence, it makes sense to allow the AP increased flexibility, namely allow it to provide different SR values for different subbands. The underlying logic is that one subband may carry highly efficient PPDU, e.g. 4 spatial streams in UL MU-MIMO, in which case the AP may want to limit the OBSS SR opportunity, whereas another subband may carry less efficient PPDU, e.g. UL OFDMA with MCS0, in which case by enabling increased OBSS SR opportunity the AP enables better spatial reuse and overall increases area throughput The number and size of the subbands is TBD, e.g. 20MHz subbands Note that currently over 30bits are available for use in SIGA of an UL Trig based PPDU Submission Slide 16 Ron Porat, Broadcom
March 2016 doc.: IEEE 802.11-15/1354r2 Strawpoll 1 Do you agree to add a Doppler bit in SIGA for HE SU and HE SU extended range, in TBD location for HE MU and in the trigger frame Yes No Abs Submission Slide 17 Ron Porat, Broadcom
March 2016 doc.: IEEE 802.11-15/1354r2 Strawpoll 2 Do you agree to add to the spec framework : 1bit is added for STBC indication in SIGA of the MU PPDU? This bit indicates STBC for all users in the payload and doesn t apply to SIGB STBC is not applied in MU-MIMO RUs Yes No Abs Submission Slide 18 Ron Porat, Broadcom
March 2016 doc.: IEEE 802.11-15/1354r2 Strawpoll 3 Do you agree to add to the TG Specification Frame work document: in trigger based UL PPDUs, multiple SR fields (>=2) are signaled, where each SR field corresponds to a different subband of the PPDU Yes No Abs Submission Slide 19 Ron Porat, Broadcom
