  • Publication number: 20220029735
    Abstract: An extremely high-throughput (EHT) station (STA) may encode an EHT PPDU for transmission on a plurality of subchannels. The EHT STA may determine a spectral mask to apply to the EHT PPDU prior to transmission of the EHT PPDU. When preamble puncturing is performed, the EHT STA may apply an overall spectral mask to the EHT PPDU prior to transmission. The overall spectral mask may be based on an interim spectral mask and a preamble-puncture spectral mask. The subchannels may be in a 6 GHz band and the EHT STA may determine if preamble puncturing is to be performed for one or more of the subchannels based on a presence of incumbents in the one or more of the subchannels, although the scope of the embodiments is not limited in this respect.
