Re: [STDS-802-11-TGBE] 11-20/1791 PDT PHY Modulation Accuracy

Good catch Edward.

 

Let me delete that part.

 

Thanks.

Best regards,

Wook Bong Lee

Hello Wook Bong,

 

Thanks for this.

 

For the first paragraph of 36.3.18.4.4, may I know if it is safe to delete the last portion of the sentence related to noncontiguous transmission?

The transmit modulation accuracy test shall be performed by instrumentation capable of converting the transmitted signals into a stream of complex samples at sampling rate greater than or equal to the bandwidth of the signal being transmitted except that for a noncontiguous transmissions each frequency segment may be tested independently.

 

 

Regards,
Edward

Hi all 11be PHY members,

 

MJ and I updated 11-20/1791, PHY modulation accuracy.

Please check revision 2. (Search for revision 2 in the note).

Table 36-45 is updated based on 26-tone indices in 11-20/1845r2 SP1 which makes same as 11ax up to 160 MHz for a single RU.

For MRU, there are several things I would like to mention.

1.       MRU index matching across different bandwidth. For small MRU, supported MRU for 20/40 and 80 are different. In that case, the MRU index is quite complex to be reflected in table 36-45. Also, there is a proposal to make some non-used indices for 80MHz and beyond. Please take a look at 11-20/1845r2 SP2. With the proposed small MRU indices, we can have a consistent way of indicating i_ru26,start.

2.       For large MRU, there are some cases where MRU is not continuous. But the table 36-45 is for continuous case. So, I wrote N/A in those cases while i_ru is matching with MRU index in section 36.3.2.3.3. I also made a note for this below the table.

Best regards,

Wook Bong Lee
