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 set of scrambling initialization bits, and may generate a scrambling sequence based on the set of scrambling initialization bits and an 11th-order polynomial. The transmitting device may provide an indication of the set of scrambling initialization bits in a physical layer convergence protocol (PLCP) protocol data unit (PPDU). The transmitting device may scramble one or more portions of the PPDU based on the scrambling sequence. The transmitting device may transmit the PPDU over a wireless medium. In some instances, the set of scrambling initialization bits consists of 11 bits, and may be included in a Service field of the PPDU.
