US Patent 10135571 Polar code processing method and system, and wireless communications apparatus

A polar code processing method and system, and a wireless communications apparatus are provided, where the method includes: acquiring at least two periodic puncturing patterns and combining the at least two periodic puncturing patterns in a predetermined manner to obtain at least two hybrid puncturing patterns; selecting, from the at least two hybrid puncturing patterns, one with a lowest frame error rate as an optimal puncturing pattern; and performing rate matching on polar polar-coded bits according to the optimal puncturing pattern, and using the rate-matched bits as to-be-transmitted bits. A frame error rate may be reduced and HARQ performance of a polar code may be enhanced.
