    Abstract: A network device polar encodes data to obtain a first encoded bit sequence, wherein the first encoded bit sequence comprises: bits in even number locations in the first encoded bit sequence and bits in odd number locations in the first encoded bit sequence; then the device interleaves the first encoded bit sequence to obtain an interleaved bit sequence; finally, the device rate matches the interleaved bit sequence and outputs the bit sequence after rate matched, wherein bits in even number locations of the interleaved bit sequence are from the bits in even number locations of the first encoded bit sequence, bits in odd number locations of the interleaved bit sequence are from the bits in odd number locations of the first encoded bit sequence.

    Abstract: Embodiments of the present invention provide a polar code rate matching method and a polar code rate matching apparatus. The method includes: performing matrix-based BRO interleaving on a non-systematic polar code output by a polar code encoder, to obtain interleaved bits; and determining, based on the interleaved bits, a rate-matched output sequence. According to the embodiments of the present invention, matrix-based BRO interleaving is performed on a non-systematic polar code, to obtain a rate-matched output sequence, so that a sequence structure after interleaving is more random, which can reduce an FER, thereby improving HARQ performance and ensuring reliability of data transmission.

    Abstract: Embodiments of the present invention disclose a data transmission method and a terminal. The method includes: detecting, by a terminal in an idle state, whether a logical channel of a first path includes first to-be-transmitted data, and whether a logical channel of a second path includes second to-be-transmitted data; and if it is detected that the logical channel of the first path does not include the first to-be-transmitted data and a length of the second to-be-transmitted data is less than a preset second path transmission data threshold, selecting the second path to transmit the second to-be-transmitted data, where the second to-be-transmitted data includes discontinuously transmitted application data whose length is less than a preset threshold.

    Abstract: This application provides a communication method, an apparatus, a device, and a storage medium. The method includes: A first device generates a first orthogonal frequency division multiplexing (OFDM) time domain signal, which occupies one subcarrier in frequency domain and is used by a second device to perform backscatter communication. The first device sends the first OFDM time domain signal to the second device. The first OFDM time domain signal occupies one subcarrier in frequency domain, such that power is concentrated on the subcarrier. When the second device performs backscatter communication based on the first OFDM time domain signal, reliability of backscatter data is improved.
