摘要： Disclosed in some examples are devices (e.g., APs, STAs, and the like), methods, and machine readable mediums which provide for proper channel estimation and frame reception in Uplink MU-MIMO systems by changing the way transmission parameters from the VHT-SIG-A are communicated to the recipients in the preamble. The transmission parameters contained in the VHT-SIG-A field may be communicated to the STAs in advance of the MU-MIMO transmissions. In other examples the transmission parameters contained in the VHT-SIG-A field may be moved to locations in the preamble that come after the VHT-STF and VHT-LTF so that the transmission parameters may be decoded.

摘要： 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.

摘要： Embodiments of an OFDM transmitter and method of reducing the effects of interference on subcarriers in an OFDM system by symbol loading are disclosed herein. A linear transformation is performed on a group of two or more input data symbols that are mapped to different signal dimensions to generate a corresponding two or more output data symbols. Each of the output data symbols has an increased number of constellation points. Each output data symbol is configured for transmission within one of the different signal dimensions. The linear transformation is configured so that each of the two or more output data symbols carry the information of each of the input data symbols of the group. This coding together of input data symbols that are mapped to different signal dimensions may provide improved reliability against fading and severe interference. The different signal dimensions may comprise a frequency, a time and/or a space dimension.
