Abstract
Embodiments of the present disclosure provide a rate matching method and an apparatus. The method includes performing, by a sending apparatus, encoding using a polar code to obtain a first encoded sequence whose length is N. A sequence number of a polarization channel may range from 0 to N−1. The method includes determining, by the sending apparatus, Pto-be-punctured bit positions. The method includes performing puncturing at the Pbit positions in the first encoded sequence to obtain rate-matched encoded bits. The Pto-be-punctured bit positions are bit positions corresponding to polarization channels 0 to P−1, Pto 3N/8−1, and/or N/2 to 5N/8−1, Pis a threshold of a quantity of to-be-punctured bit positions, and P≤N/4. The method includes sending the rate-matched encoded bits.
