Summary: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.
