摘要：<p>Disclosed are a method and device for reducing a peak-to-average power ratio, which relate to the field of communications and reduce the peak-to-average power ratio of an OFDM symbol corresponding to an SIGB field.The specific solution is: acquiring first information related to an SIGB field, the first information comprising channel bandwidth information, or the first information comprising the channel bandwidth information and modulation and coding scheme (MCS) information; and determining a target orthogonal frequency division multiplexing (OFDM) symbol of the SIGB field according to the first information, wherein the peak-to-average power ratio (PAPR) of the target OFDM symbol is less than a threshold value.The present invention is used in the process of reducing a peak-to-average power ratio.</p>
