Re: [STDS-802-11-TGAZ] IEEE submission 11-19/1572r4



Hi Rethna,

 

Thanks for the good discussions in today’s TGaz telecon.

A few more questions/comments regarding 11-19/1572r4 are listed below for your review. Thanks.

 

1.      In slide 7, it stated the max SNR degradation for channel estimation due to unintentional beamforming is 1.2494 dB, and could you please show more details how this number is derived? Also, have you evaluated how much ranging performance will be degraded by this 1.2494dB SNR loss? If the ranging performance doesn’t suffer too much, then maybe we don’t need to worry about this unintentional beamforming issue in secured ranging.

2.      In secured NDP frame for ranging, the HE-LTF field is always repeated (at least two HE-LTF fields), and one repetition will provide 3dB additional gain after combining the channel estimation results. Even if there is 1.2494dB degradation for channel estimation of a single HE-LTF field, the 3dB gain of the repeated HE-LTF field will compensate it.

3.      In slide 27, a minus sign is missed before “h11_k“ in the equation “ y1[n+1] / A2k = h11_k + h12_k’ ”

 

 

Best regards,

 

Feng Jiang
