Abstract: A method by a first wireless device in a wireless network to support simultaneous transmit-receive with a second wireless device in the wireless network using a first wireless link and a second wireless link. The method includes transmitting multi-link operation information to the second wireless device, wherein the multi-link operation information indicates a frequency separation that is to be maintained between the first wireless link and the second wireless link and transmitting a first frame to the second wireless device using the first wireless link while simultaneously receiving a second frame from the second wireless device using the second wireless link, wherein the frequency separation is maintained between the first wireless link and the second wireless link when transmitting the first frame and receiving the second frame simultaneously.

Abstract: A method is performed by a wireless device. The method comprises receiving a predetermined number N of Orthogonal Frequency Division Multiplexing (OFDM) symbols of a PHY Protocol Data Unit (PPDU), determining, using the Nth received OFDM symbol, whether the PPDU is a PPDU according to a first wireless network standard or a PPDU according to a second wireless network standard, and decoding the PPDU according to the determined wireless network standard. The predetermined number N corresponds to either a location of a Legacy Signal (L-SIG) field in the PPDU or the location of a symbol of a second field of the second wireless network standard in the PPDU, the second field being different from the L-SIG field. The first and second wireless network standards may each be a Vehicle to Everything standard or an Intelligent Transportation System standard, and may be different from each other.

Abstract: A method is described for communicating in a network. The method includes setting a type bit in a frame to indicate whether the frame is scheduling an uplink transmission for only a first set of stations in the wireless network or the first set of stations and a second set of stations in the wireless network and transmitting the frame to (1) all stations in the first set of stations when the type bit indicates that the trigger frame is scheduling the uplink transmission for the first set of stations and (2) all stations in the second set of stations when the type bit indicates that the trigger frame is scheduling the uplink transmission for the first set of stations and the second set of stations.

Abstract: A method by a wireless device functioning as a beamformer station in a wireless network to perform a sounding procedure. The method includes generating a NDPA frame, wherein the NDPA frame includes a sounding dialog token field, wherein bit B0 of the sounding dialog token field is set to binary ‘1’ and bit B1 of the sounding dialog token field is set to binary ‘1’ to indicate that the NDPA frame is an extremely high throughput (EHT) NDPA frame and wirelessly transmitting the NDPA frame to one or more beamformee stations. The NDPA frame may include an indication of whether a beamformee station should acknowledge the NDP announcement frame or not. The NDPA frame may be transmitted in a first frequency band, while a beamformed data frame is transmitted in a second frequency band that is a higher frequency band than the first frequency band.

Abstract: A method for encoding a bitstream for a frame in a wireless transmission is described. The method includes receiving, by an error correction unit of the wireless device, the bitstream; performing, by the error correction unit, forward error correction on the bitstream to generate an error corrected bitstream; determining, by a dual sub-carrier modulation (DCM) mapper of the first wireless device, a number of data subcarriers for modulating the error corrected bitstream to subcarriers in each half of an orthogonal frequency-division multiplexing (OFDM) symbol, wherein the number of data subcarriers is determined to be (1) 26 for a first bandwidth of the frame, (2) 54 for a second bandwidth and performing, by the DCM mapper, DCM on the error corrected bitstream based on the determined number of data subcarriers to generate a stream of complex numbers corresponding to the number of data subcarriers.

Abstract: A method for calibrating a radio frequency (RF) transmitter to compensate for a frequency-dependent in-phase quadrature (FDIQ) mismatch is disclosed. The method may include determining in-phase quadrature (IQ) amplitude and phase mismatches of the RF transmitter for a lower side band (LSB) and an upper side band (USB), determining a FDIQ mismatch based on linear fitting the IQ amplitude and phase mismatches for the LSB and the USB, modifying the FDIQ mismatch based on flipping a FDIQ phase mismatch in the LSB and flipping a FDIQ phase mismatch in the USB to generate a modified FDIQ mismatch, determining Fourier coefficients based on applying an inverse fast Fourier transform to the modified FDIQ mismatch, and determining FIR coefficients for a finite impulse response (FIR) filter of the RF transmitter based on windowing the Fourier coefficients.
