March 2025 doc.: IEEE 802.11-25/0392r0 Transmit and Receive Specifications for New MCS in 11bn Date: 2025-03-06 Authors: Name Alice Chen Lin Yang Daeseok Nam Bin Tian Affiliations Address Phone email alicel@qti.qualcomm.com Qualcomm Technologies Inc. Submission Slide 1 Alice Chen, et al., Qualcomm Technologies Inc.
March 2025 doc.: IEEE 802.11-25/0392r0 Introduction Transmit and receive specifications for new MCS in 11bn are TBD 11-25/354 [1] proposed Tx EVM requirements for 4 new non-ELR MCSs 11-25/98r0 [2] proposed Rx sensitivity and ACR/NACR requirements for 2 ELR- MCSs In this presentation, we discuss the following Thoughts on IEEE spec defined testing Tx EVM requirements for new non-ELR MCSs in UHR MU PPDUs Rx minimum sensitivity and ACR/NACR requirements for new ELR MCSs Submission Slide 2 Alice Chen, et al., Qualcomm Technologies Inc.
March 2025 doc.: IEEE 802.11-25/0392r0 Thoughts on Testing Similar to 11n, the testing for the non-ELR MCSs is for equal modulation (EQM) only When LDPC is used, should disable 2xLDPC Consistent to pre-UHR results for existing MCS Submission Slide 3 Alice Chen, et al., Qualcomm Technologies Inc.
March 2025 doc.: IEEE 802.11-25/0392r0 Tx EVM Proposal for Non-ELR MCSs in UHR MU PPDUs Our results are the same as [1] Relative constellation error in an UHR MU PPDU (dB) -5 -10 -12 -13 -16 -18 -19 -20 -22 -25 -27 -29 -30 -32 Coding rate Modulation BPSK QPSK QPSK QPSK 16-QAM 16-QAM 16-QAM 16-QAM 64-QAM 64-QAM 64-QAM 256-QAM 256-QAM 256-QAM 1/2 1/2 2/3 3/4 1/2 2/3 3/4 5/6 2/3 3/4 5/6 2/3 3/4 5/6 Submission Slide 4 Alice Chen, et al., Qualcomm Technologies Inc.
March 2025 doc.: IEEE 802.11-25/0392r0 Proposal for ELR MCSs Rx minimum sensitivity Same as MCS0 due to capped by CCA performance. Same as [2] Coding rate Minimum sensitivity (20 MHz PPDU) (dBm) MCS Modulation Duplication ELR- MCS0 ELR- MCS1 52-tone RU with four times duplication 52-tone RU with four times duplication BPSK 1/2 -82 QPSK 1/2 -82 ACR/NACR Same as MCS0. Same as [2] Adjacent channel rejection (dB) Nonadjacent channel rejection (dB) 20 MHz channel Coding rate MCS Modulation Duplication 20 MHz channel ELR- MCS0 ELR- MCS1 52-tone RU with four times duplication 52-tone RU with four times duplication BPSK 1/2 16 32 QPSK 1/2 16 32 Submission Slide 5 Alice Chen, et al., Qualcomm Technologies Inc.
March 2025 doc.: IEEE 802.11-25/0392r0 Summary IEEE 802.11bn spec defined testing should be consistent to legacy standards EQM only Not use 2xLDPC The non-ELR MCSs follow similar Tx EVM trend as existing MCSs ELR MCSs use same receive specification as MCS0 Submission Slide 6 Alice Chen, et al., Qualcomm Technologies Inc.
March 2025 doc.: IEEE 802.11-25/0392r0 Reference 1. 11-25/354r0, Transmit Constellation Error for Additional MCSs, Genadiy Tsodik, et. al (Huawei) 11-25/98r0, UHR Receiver Minimum Input Sensitivity for ELR MCSs, Juan Fang, et. al (Intel) 2. Submission Slide 7 Alice Chen, et al., Qualcomm Technologies Inc.
March 2025 doc.: IEEE 802.11-25/0392r0 SP1 Do you agree to include the following to the 11bn SFD? The testing in the transmit and receive specification in IEEE 802.11bn spec should only use EQM (i.e., not use UEQM) The testing in the transmit and receive specification in IEEE 802.11bn spec should not use 2xLDPC, if LDPC is used Submission Slide 8 Alice Chen, et al., Qualcomm Technologies Inc.
March 2025 doc.: IEEE 802.11-25/0392r0 SP2 Do you agree to include the following to the 11bn SFD? ELR MCSs use same Rx minimum sensitivity and ACR/NACR specifications as MCS0 Supporting doc: 11-25/392r0, 11-25/98r0 Submission Slide 9 Alice Chen, et al., Qualcomm Technologies Inc.
March 2025 doc.: IEEE 802.11-25/0392r0 APPENDIX Submission Slide 10 Alice Chen, et al., Qualcomm Technologies Inc.
