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: Techniques are described to enable a user equipment (UE) to save power consumption and/or can enable the UE to acquire the channel state in time without reducing the UE's data transmission efficiency. An example technique includes determining, by the communication device, an operating mode based on a first signaling, and operating the communication device in the operating mode, where the operating mode includes any one of a normal mode, a first power saving mode, a second power saving mode, a third power saving mode, or a fourth power saving mode.

Abstract: Methods, systems, and devices for signaling to reduce power consumption of wireless devices are described. An example method for wireless communication includes transmitting, by a network node to a wireless device in communication with the network node, a control information that is based on the wireless device being in a power-normal state or not being configured to operate in a power-saving state. Another example method for wireless communication includes receiving, by a wireless device from a network node, a control information that is based on the wireless device being in a power-normal state or not being configured to operate in a power-saving state.

Abstract: Provided are a data encoding method and device, a storage medium, and a processor. The method includes: obtaining data to be sent; performing quasi-cyclic low-density parity check (LDPC) encoding on the data to be sent to obtain an LDPC codeword sequence, and interleaving the LDPC codeword sequence to obtain an interleaved LDPC codeword sequence; performing cyclic bit selection on the interleaved LDPC codeword sequence from a starting position to obtain a rate-matched codeword sequence, where the starting position is determined according to a predetermined parameter; and sending the rate-matched codeword sequence. The solution above resolves the problem in the related art of unstable transmission after performing quasi-cyclic LDPC encoding on data to be transmitted, and achieves stable transmission after the quasi-cyclic LDPC encoding.
