Hi Mark and Youhan,

 

I think the description helps readers better understand the complicated equation.

Thanks.  I don't understand why you're proposing to add "(in the range of –8 to 7 dB)", since this is already covered by Equation (9-2):

 

 

Thanks,

 

Mark

CAUTION: This email originated from outside of the organization.

Thanks for this, Youhan.  Re CID 176 in 21/0822, please note that the comment is suggesting the following change:

 

Each Delta SNR subfield is a 2s complement signed integer that contains the ΔSNRk,i in dB, computed using Equation (9-2) and quantized to 4 bits in the range –8 dB to 7 dB with 1 dB granularity. The structure of the MU Exclusive Beamforming Report field is shown in Table 9-78 (MU Exclusive Beamforming Report information).

 

i.e. also deletes "and quantized to 4 bits in the range –8 dB to 7 dB with 1 dB granularity" (since this is duplication of the equation).

 

Thanks,

 

Mark

Hi, Mike

I have uploaded the following documents resolving comments related to Delta SNR and PHY.  Please add them to the queue (fine with future teleconferences if there is no time this week).

 

11-21/822 – CC35 Delta SNR Comments

11-21/823 – CC35 PHY Comments

 

Thanks.

Youhan
