Priority-based channel coding for control information

A method performed by a wireless transmit/receive unit, WTRU, the method comprising:

• generating first control information and second control information, wherein the first control information and the second control information are associated with a plurality of control information types, where each control information type is associated with a respective priority;
• grouping bits from the first control information and the second control information into at least two groups of bits, wherein a first group of bits comprises bits of a first priority from the first and second control information, and a second group of bits comprises bits of a second priority from the first and second control information;
• applying cyclic redundancy check (CRC) bits to one or more of the first group of bits or the second group of bits;
• and
• transmitting the first group of bits, the second group of bits, and the CRC bits to bit channels of a polar encoder, based on respective priorities of the first and second groups of bits and respective priorities of the bit channels.
