1. A method of operation of a wireless transmitter in a wireless communication network, the method comprising:
encoding a set of information carrying a number K of data bits u to generate a set of cyclic redundancy check (CRC) parity bits p along with the data bits u;
interleaving the set of CRC parity bits p and the data bits u to generate interleaved bits, the interleaving using a predetermined interleaving mapping function that depends on the number K of the data bits u and is operable to distribute some bits of the set of CRC parity bits p in front of some of the data bits u;
encoding the interleaved bits using polar coding to generate a set of encoded bits x; and
transmitting the set of encoded bits x to a wireless receiver.
