Abstract

Embodiments of this application provides a communication method in a wireless communication network. A communication device obtains an information bit sequence and obtain a first sequence, wherein the first sequence comprises sequence numbers of N channels ordered in ascending order of channel reliability, wherein N is 1024 and wherein a channel whose sequence number is 0, a channel whose sequence number is 1, and a channel whose sequence number is 2 are ordered in ascending order of channel reliability; then polar encode the information bits based on the first sequence to obtain an encoded bit sequence and output the encoded bit sequence.
