Abstract: Methods, apparatus, and systems for reducing Peak Average Power Ratio (PAPR) in signal transmissions are described. In one example aspect, a wireless communication method includes determining, for an input sequence, an output sequence. The output sequence corresponds to an output of a convolutional modulation between a set of coefficients and an intermediate sequence. The intermediate sequence is generated by inserting N zero coefficients between coefficients of the input sequence. The number of non-zero coefficients in the set of coefficients is based on N, N being a positive integer. Values of the non-zero coefficients correspond to values between 0 to π/2 to reduce a peak to average power ratio of the output sequence. The method also includes generating a waveform using the output sequence.

Abstract: This disclosure relates to methods and devices for configuring guard subcarriers in transmission subbands to reduce interband interference in a wireless communication network. In one implementation, the method may include determining that a first subcarrier spacing for a first radio frequency transmission band is less than a second subcarrier spacing for a second radio frequency transmission band, and the first radio frequency transmission band is close to the second radio frequency transmission band in frequency spectrum. The method may further include configuring a subcarrier of the first radio frequency transmission band as a guard subcarrier carrying dummy data when the first radio frequency transmission band and the second radio frequency transmission band are simultaneously used to transmit data loads.

Abstract: Methods, apparatus, and systems for reducing Peak Average Power Ratio (PAPR) in signal transmissions are described. In one example aspect, a wireless communication method includes determining, for an input sequence of coefficients, an output sequence and generating a waveform using the output sequence. The output sequence corresponds to an output of a convolutional modulation between a three-coefficient function associated with 2 2 , 1, and 2 2 and an intermediate sequence. The intermediate sequence is generated by inserting zero coefficients between coefficients of the input sequence of coefficients
