1. A method for wireless communications by a transmitting device, comprising:
encoding, by encoder circuitry of the transmitting device, a set of information bits using a low density parity check (LDPC) code to produce a code word, the LDPC code defined by a base graph having a plurality of variable nodes and a plurality of check nodes;
puncturing, by puncturing circuitry of the transmitting device, a plurality of bits at a start of the code word corresponding to at least the first variable node, having a highest degree of connectivity to the plurality of check nodes, of the plurality of variable nodes of the base graph to produce a punctured code word; and
transmitting, by transmitting circuitry of the transmitting device, the punctured code word in accordance with a radio technology across a wireless channel.
