Abstract: This application relates to the field of communications technologies, in particularly related to WIFI technologies, and provides a method and apparatus for reducing peak to average power ratio (PAPR) for transmitting a physical layer protocol data units (PPDUs) are disclosed. The method can be used for both an access point (AP) and a stations (STA). The method comprises: operating on a first disregard bits sequence to obtain a second disregard bits sequence, wherein the first disregard bits sequence is with all bits set to '1', and transmitting the PPDU, wherein the PPDU comprises the second disregard bits sequence.
