    Abstract: This disclosure provides systems, methods, and apparatuses for wireless communication that can be used to reduce the peak-to-average power ratio (PAPR) of data transmissions by increasing the degree of randomness with which data is scrambled for transmission over a wireless medium. In some implementations, a transmitting device may determine a scrambler seed value that includes at least 11 bits, where at least one of the 7 least significant bits (LSBs) of the scrambler seed value has a non-zero value. The transmitting device may generate a scrambling sequence based on the scrambler seed value and a polynomial, may construct a physical layer convergence protocol (PLCP) protocol data unit (PPDU) that includes a multi-user (MU) request-to-send (RTS) frame and the scrambler seed value, may scramble one or more portions of the PPDU based on the scrambling sequence; and may transmit the PPDU over a wireless medium.

    Abstract: This disclosure provides methods, devices, and systems for a wireless communication device to perform signal phase rotation. In some implementations, the wireless communication device may determine a number of phase rotation parameters to be applied to a number of tones of a transmission signal. In some aspects, each of the phase rotation parameters indicates a phase rotation to be applied to each of the tones according to a carrier index range for each of the tones and a bandwidth mode for the transmission signal. In some implementations, the wireless communication device may apply the phase rotation parameters to respective ones of the tones according to the specified phase rotations and the carrier index ranges, and transmit the transmission signal from the wireless communication device according to the applied phase rotation parameters.

    Abstract: This disclosure provides systems, methods and apparatuses for concurrently transmitting beamformed data from each of a plurality of access points (APs) to a wireless station (STA). In some implementations, the plurality of APs may operate as a distributed antenna array, and carrier signals of the plurality of APs may be synchronized with each other. A beamforming steering matrix may be determined for each of the plurality of APs, and beamformed data may be concurrently transmitted from each of the plurality of APs to the STA based on corresponding ones of the plurality of beamforming steering matrices.
