10 doc.: IEEE 802.11-16/0036r0 Submission 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) = D 8 +D 2 +D 1 +D 0 –E.g., 4LSB, or 4MSB Option 2: use a 4-bit CRC generator –G(D) = D 4 +g 3 D 3 +g 2 D 2 +g 1 D 1 +D 0 –E.g. 11ah with g 3 =0, g 2 =0, g 1 =1, G(D) = D 4 +D 1 +D 0 Slide 10Yakun Sun, et. al. (Marvell) Jan, 2016

11 doc.: IEEE 802.11-16/0036r0 Submission 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 Jan, 2016 Yakun Sun, et. al. (Marvell)Slide 11

12 doc.: IEEE 802.11-16/0036r0 Submission False Positive Rate Slide 12Yakun Sun, et. al. (Marvell) G = [g 1, g 2, g 3 ] 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 Jan, 2016

13 doc.: IEEE 802.11-16/0036r0 Submission 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. Slide 13Yakun Sun, et. al. (Marvell) Jan, 2016

14 doc.: IEEE 802.11-16/0036r0 Submission 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? Slide 14Yakun Sun, et. al. (Marvell) Jan, 2016
