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 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.
