1. A method implemented by a wireless transmit/receive unit (WTRU), the method comprising:
polar encoding a plurality of information bits and one or more cyclic redundancy check (CRC) bits, wherein the polar encoding is performed according to a code construction of the plurality of information bits and the one or more CRC bits, and wherein the one or more CRC bits are determined using a plurality of output bits of one or more component polar codes of the polar encoding; and
sending a transmission including information indicating the polar encoded information bits and the polar encoded one or more CRC bits.
