Hello Bo,

11ax definition for INACTIVE_SUBCHANNELS in Table 27-1 does not support in 11be.
But, not only for INACTIVE_SUBCHANNELS, we can't use the 11ac definition for CH_BANDWIDTH_IN_NON_HT. CBW320M is not defined in 11ac.

So, in your document 11-20/1403, the following is wrong. For now, we should say it as TBD.

CH_BANDWIDTH_IN_NON_HT	FORMAT is EHT_MU or EHT_TB	Not present	N	N
CH_BANDWIDTH_IN_NON_HT	Otherwise	~~See corresponding entry in Table 21-1 (TXVECTOR and RXVECTOR parameters) or Table 27-1 (TXVECTOR and RXVECTOR parameters).~~ TBD

Thanks,

Yongho

Hello, Yanjun,

Thanks for initiaing the discussion.

For your reference, the current 11ax TXVECTOR parameter INACTIVE_SUBCHANNELS is present and indicates the 20 MHz subchannels that are punctured when "FORMAT is NON_HT and NON_HT_MODULATION is NON_HT_DUP_OFDM".

In 11be, Table 34-1 will contain parameter INACTIVE_SUBCHANNELS as well to extend support for FORMAT=EHT_MU. But for NON_HT case, the use of this parameter may refer to the definition as in 11ax Table 27-1. My question is whether current definition for INACTIVE_SUBCHANNELS in Table 27-1 supports the description in your proposal?

Best Regards,
Bo
