  • Patent number: 11962406
    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.

  • Patent number: 11924866
    Abstract: Embodiments of an Extremely High Throughput Station (EHT STA) (STA1) configured for operating in a next-generation (NG) wireless local area network (WLAN) are described herein. In some embodiments, the EHT STA encodes a common signal field (SIG) (Coex-SIG) of an EHT PPDU to include a TXOP duration field. The TXOP duration field is more than seven bits to indicate an actual TXOP duration of a transmission from the EHT STA comprising the EHT PPDU transmitted to a second station (STA2). Decoding the TXOP duration field of the EHT PPDU by a third-party station (STA4) causes the third-party station (STA4) to defer a transmission until after an end of the transmission from the second station (STA2).
