doc.: IEEE /0044r0 Submission Introduction We have agreed to use 1024 QAM as an optional feature in 11ax This contribution proposes new MCS levels and TX EVM requirement for 1024 QAM In appendix, simulation results considering various channel configurations are presented Slide 9Eunsung Park, LG Electronics January 2016

doc.: IEEE /0044r0 Submission Proposal We suggest to add the following new MCS levels into HE-MCSs as an optional feature MCS 10: 1024 QAM with 3/4 code rate MCS 11: 1024 QAM with 5/6 code rate –We choose two code rates among four code rates (1/2, 2/3, 3/4, 5/6) used in 11ac –Only these two MCS levels enable to transmit larger information bits than those in 11ac –Note that the proposed MCS levels provide average throughput enhancement as well as peak throughput increase [1] We suggest to use TX EVM requirement of -35dB for 1024 QAM –Note that EVM of -35dB given to the proposed MCS levels offers reasonable performance (about 1dB loss) as shown in [1] and appendix Eunsung Park, LG ElectronicsSlide 10 January 2016
