Embodiments of the present disclosure relate to devices, methods, apparatus and computer readable storage media of CRC optimization. The method includes generating a set of decoded sequences of an encoded signal received from a second device; determining an activation state of a cycle redundant check based on an actual distribution property associated with the set of decoded sequences and a reference distribution property associated with the set of decoded sequences; and determining a likelihood of successful decoding at least based on the activation state. In this way, the FAR can be reduced and the expected joint FAR and BLER optimization can be achieved.

Example embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of enhanced decoding for polarization code. The method includes determining a likelihood sequence associated with a signal sequence received from a second device via a communication channel between the second device and the first device; generating a set of candidate sequences of the signal by processing the likelihood sequence with a first operation; determining a reference sequence by processing the likelihood sequence with a second operation different from the first operation; and determining a target sequence of the signal from the set of candidate sequences at least partially based on the reference sequence. In this way, the decoding at receiver side can be enhanced to less rely on CRC during decoding. This could dramatically improve the overall performance of the channel.
