Abstract
Embodiments of this application provide a method for processing information bits in a wireless communication network. A communication device obtains K information bits and a code length M. The code length M is a length of an output sequence resulting from processing the information bits. The communication device generates an N-bit bit sequence that includes the K information bits and one or more parity check bits, encodes the bit sequence using a polar encoding formula to obtain an N-bit encoded sequence, rate matches the encoded sequence to obtain the output sequence, and outputs the output sequence. When M−K>192, in the bit sequence, one of the parity check bits is placed in a bit position that is determined according to reliabilities of the bit positions in the bit sequence for placing the K information bits and the one or more parity check bits.
