Re: [STDS-802-11-TGBP] Sub-1 GHz AMP Downlink PPDU PDT

Hi Panpan,

 

                I believe the motion you are referring to is,

 

  • PM-59:
  • 11bp shall adopt the following channelization scheme for EU:
    • Bands: 865-868MHz
    • BW: 200kHz
    • Channel center frequency: 865.1+N*0.2, N=0,…,14;
  • Note: support of 400kHz bandwidth in 915-921MHz is TBD.

[Motion #136, [1] and [123]]

 

                I added Bo to see what he thinks.  If this is sufficient to drop the 11ah preamble, I can do that.  If not maybe you can make an explicit motion to modify your earlier motion and delete the 11ah preamble.  For now, I will work on modifying the PDT accordingly.

 

Regards,
Steve

Hi Steve,

 

The existing PDT shows the existence of “IEEE 802.11ah preamble” is TBD.

The main reason we left it TBD when we run the SP several moths ago was that the US channelization in sub-1GHz was TBD and those two are related.

Now since we have passed the motion regarding US channelization in sub-1GHz, which defines contiguous channels (no overlapping no spacing with BW 250kHz), it really doesn’t support the existence of 11ah preamble.

 

Can we delete the “IEEE 802.11ah preamble” in PDT?

 

 

Best,

Panpan
