Abstract

Methods and devices for puncturing of a polar code in a wireless network, wherein nested puncturing sets are determined based on a puncturing order which is determined based on a reliability order of information bit channels, so that only one index sequence needs to be stored for both the determination of the information set and the determination of the punctured set and so that puncturing does not require to adjust the information set at error prone indexes corresponding to puncturing indexes. The puncturing order might start with indexes corresponding to high reliability bit channels or to low reliability bit channels.
