Title:
METHOD AND DEVICE FOR RATE MATCHING AND DE-RATE MATCHING POLAR CODE
Document Type and Number:
WIPO Patent Application WO/2019/206136
Kind Code:
A1
Abstract:
Provided by the embodiments of the present application are a method and device for rate matching and de-rate matching a polar code, the method comprising: acquiring a sequence to be coded of which the length is N according to a coding constraint relationship, and performing polarization coding on the sequence to be coded so as to obtain a coded sequence, the coding constraint relationship being used to indicate at least two constraint positions in the sequence to be coded, and bits located at the at least two constraint positions having the same value; obtaining, according to matching positions in a rate matching pattern and the coded sequence, a rate matching sequence of which the length is M, wherein the rate matching pattern comprises a plurality of consecutive matching positions, and coded bits corresponding to the matching positions in the coded sequence are 0, N and M being integers, and M being less than N; and sending the rate matching sequence to a receiving device. The embodiments of the present application may improve decoding performance.
