Abstract
There is provided mechanisms for decoding an encoded sequence into a decoded sequence. A method is performed by an information decoder. The method comprises obtaining the encoded sequence. The encoded sequence has been encoded using a polar code. The method comprises successively decoding the encoded sequence into the decoded sequence. The decoding is performed for a given list size, LS, where LS>1, defining how many candidate decoded sequences in total the thus far decoded sequence is allowed to branch into during the decoding. The encoded sequence is decoded, until its first branching, by at least as many processing units in parallel as a factor, f, of the given list size. The factor is at least half the given list size, f≥LS/2.
