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 process for receiving a Physical Layer Protocol Data Unit (PPDU) may include receiving a first portion of the PPDU. The first portion including a Legacy Signal (L-SIG) field and a second signal field that is received after the reception of the L-SIG field. The process further includes decoding, using first information in the L-SIG field, the second signal field, and determining, using second information included in the second signal field, that the PPDU includes midambles. In response to determining that the PPDU includes midambles, the process determines, using a midamble periodicity M, a number of midambles NMA in the PPDU, determines, using the number of midambles, a number of data symbols in a data field of the PPDU, and processes, using the number of midambles and the number of data symbols, the data field of the PPDU. The process may be performed by a wireless device.

Abstract: A method is described for aligning high efficiency (HE), extremely high throughput (EHT), and EHT+sub-physical layer protocol data units (sub-PPDUs) included in an aggregated PPDU (APPDU) trigger frame. The method includes aligning a preamble portion of the sub-PPDUs by applying a multi-user PPDU (MU-PPDU) format to each of the sub-PPDUs and aligning a data portion of the sub-PPDUs by including a padding subfield in each of the sub-PPDUs to produce a common length.

Abstract: A method for channel sounding for high efficiency (HE) and extreme high throughput (EHT) stations (STAs) includes receiving, by a station (STA), an aggregate physical layer protocol data unit (A-PPDU) from an access point (AP), the A-PPDU including an HE sounding null data packet (NDP) and an EHT sounding NDP, receiving, by the STA, a beamforming report poll frame (BFRP) from the AP, and receiving, by the STA, one or more compressed beamforming (BF)/channel quality indicator (CQI) frames. The HE sounding NDP or the EHT sounding NDP overlaps 242-tone resource units (RUs) corresponding to bits with a value of 1 in the bitmap of the TXVECTOR parameter INACTIVE_SUBCHANNELS or overlaps a punctured center 26-tone RU of an HE sounding NDP, the HE sounding NDP or the EHT sounding NDP being punctured.

Abstract: A method for encoding a bitstream is described. The method includes receiving, by an error correction unit, the bitstream; performing, by the error correction unit, encoding on the bitstream to generate an encoded bit stream that includes the bitstream and parity bits; processing, by a constellation unit, the encoded bitstream to generate constellation points in one or more encoded streams; determining, by a low-density parity-check (LDPC) tone mapper, a distance between subcarriers in an Orthogonal Frequency Division Multiplexing (OFDM) symbol of the frame; and performing, by the LDPC tone mapper, LDPC tone mapping based on the one or more encoded streams and on the determined distance to generate a permuted stream of complex numbers, wherein the distance between subcarriers is determined to be either (1) 18 for a first resource unit size used in the frame and (2) 20 for a second resource unit size used in the frame.

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.

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.
