Polar coding for beam sweeping broadcast channel

A method in a wireless receiver, the method comprising:

• receiving a first signal block on a first beam, the first signal block comprising a first set of bits encoded with a channel code and representing a non-time-varying component and a second set of bits encoded with the channel code and representing a first time-varying component, wherein cyclic redundancy check (CRC) bits is determined for the concatenated first and second set of bits, the determined CRC bits is concatenated to the concatenated first and second set of bits, wherein the second set of bits is utilized twice, such that the second set of bits (i) is utilized within the CRC bits and (ii) is carried as a part of information bits within the concatenated CRC bits and the first and second set of bits;
• and
• decoding the first set of coded bits by decoding the first signal block.
