1. A method for wireless communications, the method comprising:
obtaining a set of information bits;
generating a lifted low density parity check (LDPC) code via a lifting size value from a plurality of families of lifting size values, the plurality of families of lifting size values including a first family of lifting size values and a second family of lifting size values, wherein the first family of lifting size values comprises products of a first integer and each of a plurality of powers of two and the second family of lifting size values comprises products of a second integer and each of the plurality of powers of two, and wherein the first integer is different than the second integer;
applying a 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;
encoding the set of information bits based on the lifted LDPC code to produce one or more codewords; and
transmitting signaling associated with the one or more codewords in accordance with a radio technology across a wireless channel.
