Abstract: Embodiments of this application provide a method and an apparatus for constructing a coding sequence. The method includes: storing a reliability sequence corresponding to a basic sequence, where a length of the reliability sequence corresponding to the basic sequence is less than or equal to a length of a reliability sequence corresponding to a mother code sequence; storing a reliability reference sequence, where the reliability reference sequence includes at least one element remaining after the reliability sequence corresponding to the basic sequence is excluded from the reliability sequence corresponding to the mother code sequence; and constructing a coding sequence by using the reliability sequence corresponding to the basic sequence and an element in the reliability reference sequence. During implementation of this application, during storage, only the reliability sequence corresponding to the basic sequence and the reliability reference sequence are stored. Because a sum of the length of the reliability sequence corresponding to the basic sequence and a length of the reliability reference sequence is far less than the length of the original reliability sequence, storage overheads can be reduced.

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.

Abstract: This application provides a method for communicating a modulation and coding scheme (MCS). A terminal device obtains a modulation order, a code rate, or a spectral efficiency, determines an index of a reference MCS from a mapping table based on the obtained modulation order, code rate, or spectral efficiency, and reports the index of the reference MCS to a network device. The mapping table includes one or more mapping relationships between an MCS index and a modulation order, a code rate, or a spectral efficiency. The terminal device may process uplink or downlink data based on the determined MCS, thereby improving data transmission reliability.

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.
