Enhanced information sequences for polar codes

A transmit node comprising:

• a polar encoder operable to perform polar encoding of a set of K information bits to thereby generate a set of polar-encoded information bits where:
• the K information bits are mapped to the first K information bit locations specified in an information sequence SN, the information sequence SN being a ranked sequence of N information bit locations among a plurality of input bits for the polar encoding where Nis equivalent to a code length;
