Title:
POLAR CODE ENCODING METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/098461
Kind Code:
A1
Abstract:
The present application relates to the field of communication technology, and discloses a Polar code encoding and decoding method and device, for improving sequence searching efficiency. Said method is as follows: acquiring a first sequence, according to encoding parameters, from a Polar code construction sequence list, the Polar code construction sequence list comprising at least one encoding parameter and at least one sequence corresponding to the at least one encoding parameter, the encoding parameters being mapped to sequences on a one-to-one basis, a first sequence being one of the at least one sequence, the first sequence being composed of polarized channel sequence numbers arranged in an ascending order or in a descending order according to the polarized channel reliability corresponding to the polarized channel sequence numbers, the encoding parameters including at least one of the length of a mother code, the number of bits of information to be encoded, and the number of bits after rate matching; and selecting from the first sequence, according to the rate matching scheme and/or the reliability ranking, the sequence numbers of K polarization channels, placing, according to the sequence numbers of the selected K polarization channels, the bits to be encoded, and performing Polar code encoding, to obtain an encoded bit sequence.
