Jan, 2016 doc.: IEEE 802.11-16/0036r0 Overview HE-SIGA and each coding group in HE-SIGB has 4-bit CRC. The exact CRC generator hasn t been determined. Option 1: use 4 out of 8-bit CRC as in HT-SIG G(D) = D8+D2+D1+D0 E.g., 4LSB, or 4MSB Option 2: use a 4-bit CRC generator G(D) = D4+g3D3+g2D2+g1D1+D0 E.g. 11ah with g3=0, g2=0, g1=1, G(D) = D4+D1+D0 Submission Yakun Sun, et. al. (Marvell) Slide 10
Jan, 2016 doc.: IEEE 802.11-16/0036r0 Simulation Assumptions Use HE-SIG-A as an example (each coding group in HESIGB has less or similar number of bits as in HESIGA). SIGA has 52-4-6 = 42 info bits for CRC generation. SIGB common block has 8x4 = 32 info bits for CRC generation. SIGB user specific coding block = 21*2 = 42 info bits. Simulated false positive probability of a CRC generator: A false positive happens when a HESIGA is decoded incorrectly but CRC check is passed. CRC is generated by 4 LSB or 4 MSB of 8-bit HT CRC generator output All possible [g1, g2, g3] for a 4-bit CRC generator Submission Slide 11 Yakun Sun, et. al. (Marvell)
Jan, 2016 doc.: IEEE 802.11-16/0036r0 False Positive Rate G = [g1, g2, g3] for 4-bit CRC generator, e.g. G=[1, 0, 0] for 11ah 4-bit CRC Most of 4-bit generator has similar false positive performance (11ah generator has the best performance). 4 LSB/MSB of 8bit HT CRC performs close to 11ah CRC and better than other 4-bit CRC 20MHz, AWGN, HE-SIG-A 20MHz, DNLOS, HE-SIG-A 0 10 0 10 4bit, G=[0 0 0] 4bit, G=[0 0 1] 4bit, G=[0 1 0] 4bit, G=[0 1 1] -1 10 -1 10 4bit, G=[1 0 0] 4bit, G=[0 0 0] 4bit, G=[1 0 1] 4bit, G=[1 1 0] 4bit, G=[0 0 1] Error Rate 4bit, G=[0 1 0] Error Rate 4bit, G=[1 1 1] -2 10 -2 10 4bit, G=[0 1 1] 4LSB of 8bit CRC 4bit, G=[1 0 0] 4MSB of 8bit CRC 4bit, G=[1 0 1] 4bit, G=[1 1 0] PER, HESIGA -3 10 -3 10 4bit, G=[1 1 1] 4LSB of 8bit CRC 4MSB of 8bit CRC PER, HESIGA -4 10 -4 10 -3 -2.5 -2 -1.5 -1 -0.5 0 0.5 1 1.5 2 -3 -2 -1 0 1 2 3 4 5 SNR (dB) SNR (dB) Yakun Sun, et. al.

Jan, 2016 doc.: IEEE 802.11-16/0036r0 Conclusions 4 LSB/MSB of 8-bit CRC performs at minimum loss to the optimal 4bit CRC. 4LSB is slightly better than 4MSB. 8-bit CRC has to be implemented in every device. Apply 4LSB or 4MSB at no cost. Submission Yakun Sun, et. al. (Marvell) Slide 13
Jan, 2016 doc.: IEEE 802.11-16/0036r0 SP Do you support to add the following in the current SFD: The CRC bits of HE-SIG-A and each coding group of HE-SIG-B are generated as 4 LSB of HT CRC generator output? Submission Yakun Sun, et. al. (Marvell) Slide 14
