Abstract: Example polar coding methods and apparatus are described. One example method includes determining a sequence used to code to-be-coded bits. Polar coding is performed on the to-be-coded bits by using the sequence to obtain coded bits. The sequence is used to represent a reliability order of N polarized channels, N is a mother code length of a polar code, and N is a positive integer power of 2.

Abstract: The application provides manner for communicating channel state information (CSI) in a communication network. A preset length is used for equalizing lengths of CSI to be reported. The preset length is determined based on a quantity of CSI-reference signal (RS) ports. A communication device determines whether a total length of one or more indication information items to be included in the CSI is less than the preset length. If the total length of the one or more indication information items to be included in the CSI is less than the preset length, the communication device adds one or more padding bits, to obtain a CSI bit sequence including the one or more indication information items and the one or more padding bits. A total length of the CSI bit sequence is consistent with the preset length. The communication device then outputs the CSI bit sequence.
