    Abstract: Embodiments of this application provide a method for transmitting encoded information. A communication device obtains K bits of information, and generates a to-be-encoded sequence u1N, wherein N is a length of the sequence. The device encodes the sequence u1N in an encoding process, to obtain an output sequence, and transmits the output sequence. In the sequence u1N, each of the N bits corresponds to a subchannel, and each subchannel has a reliability. The K information bits, a quantity J of first-type auxiliary bits, and a quantity J′ of second-type auxiliary bits are placed in K′=K+J+J′ bit positions of the sequence u1N according to reliabilities of the subchannels. Since the positions of the information bits and the auxiliary bits are pre-determined and not affected by subsequent encoding and rate-matching, overheads of real-time reliability calculation are effectively reduced, time is saved, and delay is reduced.

    Abstract: Embodiments of this application provide a channel encoding method for use by a communication device. The communication device obtains a quantity K of information bits, and determines a load size of a channel for transmitting the K information bits. The load size of the channel is N bits, where N≥K, N=2n, and n is a positive integer. The communication device performs a polar encoding process on the K information bits, to obtain a polar code sequence that includes N bits. The N-bit polar code sequence is transmitted using the channel, without rate matching. Because a quantity of coded bits obtained after the polar encoding is equal to a load size of a channel, no rate matching process is required. This reduces encoding overheads of a channel. Complexity and latency of channel encoding are greatly reduced, and performance loss associated with the rate matching operation is avoided.

    Abstract: 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.

    Abstract: Embodiments of the application provide a method for rate matching in a wireless communication network. A device obtains K information bits and a target code length M of a polar code, determines, according to a minimum value of a set of values, a mother code length N1, polar encodes the K information bits to obtain an encoded sequence of N1 bits, obtains a target sequence of M bits from the N1 bit encoded sequence, and outputs the M-bit target sequence. When the mother code length N1 is larger than the target code length M, (N1−M) bits of the encoded sequence are punctured or shortened from the N1 bit encoded sequence.

    Abstract: Embodiments of this application provide a method for encoding data in a wireless communication network. A communication device obtains an information bit sequence of a bit length K and a code length M. When M is greater than or equal to a first threshold and K is greater than or equal to a second threshold, the device divides the information bit sequence into p subsequences that are of an equal length K1. Then the device encodes each of the p subsequence to obtain p encoded subsequences. The device rate-matches each of the p encoded subsequences to obtain p rate matched subsequences, concatenates the p rate matched subsequences to obtain the output sequence of the code length M, then outputs the output sequence.
