Classification: CPC H | IPC H

Claim 27:
28. An apparatus for wireless communications, comprising:
encoder circuitry configured to:
obtain a set of information bits;
generate a lifted low density parity check (LDPC) code, the encoder circuitry further being configured to:
determine a lifting size value from a tower of lifting size values, the tower of lifting size values comprising products of a plurality of powers of an integer and a plurality of different lifting size values;
determine a set of cyclic lifting values; and
apply the set of cyclic lifting values to interconnect edges in a number of copies of a base parity check matrix (PCM), the number of copies corresponding to the lifting size value; and

encode the set of information bits based on the lifted LDPC code to produce one or more codewords; and

transmitter circuitry configured to transmit the one or more codewords in accordance with a radio technology across a wireless channel.
