Claim 2:
3. The apparatus of claim 1, wherein when the one or more punctured subchannels comprise an edge subchannel,
the processing circuitry is configured to:
determine a mask value for the overall spectral mask,
wherein for each frequency where a non-preamble-puncture spectral mask has a value of zero decibels relative to a reference level (dBr) and the preamble-puncture spectral mask does not have a value in an occupied one of the subchannels, the processing circuitry is to set the mask value for the overall spectral mask to zero dBr, 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 −40 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; and
apply the overall spectral mask at an edge of an occupied one of the subchannels, the edge of the occupied subchannel being adjacent to one of the punctured subchannels.
