Claim 3:
4. The apparatus of claim 1, wherein when two or more adjacent subchannels within a central portion of the EHT PPDU are punctured, the two or more adjacent subchannels comprising a lowest punctured subchannel and a highest punctured subchannel,
the processing circuitry is configured to:
apply a lower subchannel edge mask at a lower edge at the lowest punctured subchannel and apply a higher subchannel edge mask at a higher edge of the highest punctured subchannel;
determine mask values for the overall spectral mask,
wherein for each frequency where the lower subchannel edge mask and the higher subchannel edge mask have a value greater than −25 dBr and less that −20 dBr, the processing circuitry is to set the mask value for the overall spectral mask to a larger value of the lower subchannel edge mask and the higher subchannel edge mask, and
wherein for each frequency where a non-preamble-puncture spectral mask has a value and the preamble-puncture spectral mask does not have a value in an occupied subchannel, the processing circuitry is to set the mask value for the overall spectral mask to the value of the non-preamble-puncture spectral mask, and
wherein for other frequencies where the non-preamble-puncture spectral mask and the preamble-puncture spectral mask both have values greater or equal to −25 dBr, the processing circuitry is to set the mask value for the overall spectral mask to a lower value of the non-preamble-puncture spectral mask and the preamble-puncture spectral mask.
