摘要： This application provides a polar coding method, a polar decoding method, and an apparatus. A transmit end obtains K to-be-coded bits and an index set including K polar channels, where a value set of K1 indexes in the set of the K indexes or a value set of K2 indexes in the set of the K indexes is determined based on a value set of K2 of the K to-be-coded bits, and the value set of the K1 indexes and the value set of the K2 indexes are complementary sets of each other; and performs polar coding on K1 to-be-coded bits. In comparison with a conventional polar coding method and a conventional polar decoding method, the polar coding method and the polar decoding method provided in this application can achieve an effect of reducing a bit rate. A simulation result indicates that the method has better performance.

摘要： Embodiments of the application provide a method for transmitting data in a wireless communication network. A device of the network receives a bit sequence of K information bits. The device polar codes the bit sequence to obtain a first encoded sequence, wherein a length of the first encoded sequence is N, and N is greater than or equal to K. The device block interleaves the first encoded sequence to obtain an interleaved bit sequence. The device determines a transmission code rate R. When the transmission code rate R is less than the code rate threshold, the device outputs a second bit sequence. The length of the second bit sequence is M, M is smaller than N. The second bit sequence is punctured from the interleaved bit sequence by removing (N−M) bits from beginning of the interleaved bit sequence.

摘要： An interleaving method and apparatus are provided, to reduce complexity of implementation processes of polar code interleaving and rate matching. The method includes: obtaining encoded bits after polar code encoding, and sorting the encoded bits based on a priority order of performing a rate matching operation, to obtain a first bit sequence. The first bit sequence includes j subsequences, and j is a positive integer. The method further includes writing the first bit sequence into an interleaver of i rows and j columns. Bits in a column in the interleaver include one of the j subsequences; and reading out bits from the interleaver column by column, until M bits are read. At least two adjacent columns have opposite readout directions, and M is a target code length.

摘要： Embodiments of the present invention provide a coding method, where the coding method includes: obtaining, based on a puncturing/shortening proportion P′ and a prestored sequence S′, a constructed sequence S that has a length equal to a target code length M, where S′ includes N′ channel indexes sorted by channel reliability or channel capacity, and sorting of channel indexes in S is the same as or different from sorting of channel indexes in S′; and mapping a to-be-sent bit sequence to a channel corresponding to S. According to this method, an appropriate constructed sequence S may be generated based on different puncturing/shortening proportions to perform coding, thereby decreasing a bit error rate.
