U-Sig No
The U-SIG content shall be identical in each non-punctured 20 MHz subchannels
within each 80 MHz subblock, while it can be different in each 80 MHz subblocks
when BW is greater than 80MHz.
You can choose ‘U-SIG No’ to see decoded information for each 80 MHz subblock.

EHT SIG No
For OFDMA transmission or non-OFDMA transmission to multiple users, EHT-SIG
field when BW is greater than 80 MHz contains two EHT-SIG content channels per
80 MHz and the EHT-SIG content channels per 80 MHz are allowed to carry
different information.
You can choose EHT-SIG No to see EHT-SIG filed decoded information for each 80
MHz subblock.
