Introduction November 2015
Previously in [1], fields in HE-SIG-A were defined separately for the SU preamble format and MU preamble format Fields added to the Specification Framework Document (PHY Motions 43/44/45/46/48/54 in [2]) In this contribution, we provide a more organized table structures for those preamble formats and the trigger based UL preamble format which include New fields Bitwidth for some of those fields The intention is to replace the current definition in the spec framework with the new tables providing a clean and accurate reference for all currently defined fields in SIGA The definition of the preamble formats is further clarified in [3] Ron Porat, Broadcom
11
SIG-A Table for the SU Preamble Format
November 2015 SIG-A Table for the SU Preamble Format Brief explanation Format indication: distinguish between SU and trigger based UL [1] BSS Color: Base station identifier [2] Spatial reuse: Exact bits TBD e.g. indicaation of CCA Level, Interference Level accepted, TX Power TXOP Duration: [1] CP + LTF Size: [3] DCM: Dual carrier modulation indication [2] Packet extension: “a”-factor field of 2 bits and 1 disambiguation bit [2] Beam change: Indicate precoder change/no change between L-LTF and HE-LTF [4] Field #Bits DL/UL 1 Format Indication BSS Color 6 Spatial Reuse TBD TXOP duration Bandwidth 2 MCS 4 CP+LTF size 3 Coding Nsts STBC TxBF DCM Packet Extension Beam change CRC Tail Ron Porat, Broadcom
12
SIG-A Table for the MU Preamble Format
November 2015 SIG-A Table for the MU Preamble Format Brief explanation Refer to previous slide for explanation on bits similar to the SU format SIGB Modulation: [5] #SIGB symbols: <= 16 (4 bits) support about 16 users using MCS0 per BCC Compression mode: Differentiates full bandwidth MU-MIMO from OFDMA MU PPDU [6]. More compression modes TBD #LTFs: Up to 8 LTFs possible → 3 bits LDPC extra symbol: [2] BW field may accommodate more than in SU case to take advantage of OFDMA Field #Bits DL/UL 1 BSS Color 6 Spatial Reuse TBD TXOP duration Bandwidth >=2 SIGB MCS 3 SIGB DCM SIGB # of symbols 4 SIGB Compression Mode >=1 # of HE-LTF CP+LTF size LDPC extra symbol Packet Extension CRC Tail Ron Porat, Broadcom
13
SIG-A Table for the Trigger based UL Preamble Format
November 2015 SIG-A Table for the Trigger based UL Preamble Format Field #Bits Format 1 BSS Color 6 TXOP TBD Spatial reuse Bandwidth CRC 4 Tail Brief explanation Format indication: distinguish between SU and UL MU PPDUs [1] BSS Color: Base station identifier [2] Spatial reuse: Exact bits TBD but examples given in Appendix → CCA Level, Interference Level, TX Power TXOP Duration: [1] Ron Porat, Broadcom

November 2015 Strawpoll 1 Do you agree to add to the TG Specification Frame work document: the HE-SIG-A field definitions for SU preamble format in [2] (PHY Motions 43, 46, 48, 54) shall be replaced with the table in slide 11? Yes No Abs Ron Porat, Broadcom
16
November 2015 Strawpoll 2 Do you agree to add to the TG Specification Frame work document: the HE-SIG-A field definition for the MU preamble format [2] (PHY Motions 44, 46, 54) shall be replaced with the table in slide 12? Yes No Abs Ron Porat, Broadcom
17
November 2015 Strawpoll 3 Do you agree to add to the TG Specification Frame work document: the HE-SIG-A field definition for trigger based UL preamble format in [2] (PHY Motion 45) shall be replaced with the table in slide 13? Yes No Abs Ron Porat, Broadcom
