Title:
DATA TRANSMISSION METHOD AND RELATED DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/171790
Kind Code:
A1
Abstract:
Provided in embodiments of the present application are a polar coding method and a coding device. The method comprises: acquiring information block to be transmitted and a target code length M of a polar code; determining the code length N of a parent code employed for polar coding, insofar as the target code length M is greater than N, if a coding parameter of the information block satisfies a preset criterion, dividing a bit sequence of the information to be coded into p subsections, independently polar coding the p subsections respectively to produce p coding bit sequences of which the length is the length of the parent code for the respective subsections, performing rate matching with respect respectively to p coding results to produce p coding bit sequences of which the length is the target code length of the subsections; and merging the rate matched p coding bit sequences to produce a coding bit sequence of which the length is M, where p is an integer greater than or equal to 2. The coding method reduces the number of times that a repeating rate matching solution is used, thus mitigating performance loss brought forth by repetition.
