1. A method for wireless communication, comprising:
generating a first plurality of vectors each comprising a respective set of information bits having a first quantity, wherein each vector of the first plurality is associated with a respective index indicating an order of the first plurality of vectors with respect to a lifted parity check matrix;
replacing a first set of information bits of a first vector of the first plurality of vectors with a first set of parity bits having the first quantity, wherein the first set of parity bits is based at least in part on the first set of information bits;
encoding the first plurality of vectors according to the lifted parity check matrix and the replacing; and
performing, at a first wireless device, a transmission to a second wireless device based at least in part on the encoding.
