1. A method for wireless communications by a user equipment (UE) comprising a processor in electrical communication with a memory, the processor configured to obtain data from the memory in preparation for wireless communications, the method comprising:
receiving control information indicating a modulation order, a coding rate, and a resource allocation (RA) for transmission of a codeword;
selecting a base graph (BG) from which to derive a low density parity check (LDPC) code for use in decoding the codeword, wherein the selecting is based on the coding rate and the RA;
receiving the codeword via resources of the RA; and
decoding the codeword using the LDPC code derived from the selected BG.
