Spectral masks for subchannel puncturing in EHT networks

A non-transitory computer-readable storage medium that stores instructions for execution by processing circuitry of an extremely high-throughput (EHT) station (STA) to configure the EHT STA to:

• encode an EHT physical layer protocol data unit may be a physical layer conformance procedure (PLCP) protocol data unit (PPDU) for transmission on a plurality of subchannels, the EHT PPDU comprising a preamble portion and a subsequent portion;
• and
• determine a spectral mask to apply to the EHT PPDU prior to transmission of the EHT PPDU,
• wherein when preamble puncturing is performed, the processing circuitry is configured to:
• apply an overall spectral mask to the EHT PPDU prior to transmission by applying an interim spectral mask and further applying a preamble-puncture spectral mask to the EHT PPDU;
• and
• configure the EHT PPDU for transmission on each of the subchannels of the plurality except for one or more punctured subchannels of the plurality,
• wherein when the preamble puncturing is not performed, the processing circuitry is configured to:
• configure the EHT PPDU for transmission on each of the subchannels of the plurality by only applying the interim spectral mask to the EHT PPDU,
• wherein the preamble-puncture spectral mask is determined based on whether the one or more punctured subchannels comprise edge subchannels or comprise middle subchannels of the EHT PPDU.

An apparatus of an extremely high-throughput (EHT) station (STA), the EHT station comprising:

• processing circuitry;
• and memory, wherein the processing circuitry is configured to:
• encode an EHT physical layer protocol data unit may be a physical layer conformance procedure (PLCP) protocol data unit (PPDU) for transmission on a plurality of subchannels in a 6 GHz band, the EHT PPDU comprising a preamble portion and a subsequent portion;
• and
• determine a spectral mask to apply to the EHT PPDU prior to transmission of the EHT PPDU;
• 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;
• and
• wherein when preamble puncturing is performed, the processing circuitry is configured to:
• apply an overall spectral mask to the EHT PPDU prior to transmission by applying an interim spectral mask and further applying a preamble-puncture spectral mask to the EHT PPDU;
• and
• configure the EHT PPDU for transmission on each of the subchannels of the plurality except for one or more punctured subchannels of the plurality,
• wherein when the preamble puncturing is not performed, the processing circuitry is configured to:
• configure the EHT PPDU for transmission on each of the subchannels of the plurality by only applying the interim spectral mask to the EHT PPDU,
• wherein the preamble-puncture spectral mask is determined based on whether the one or more punctured subchannels comprise edge subchannels or comprise middle subchannels of the EHT PPDU.
