Wireless communications systems and methods related to hybrid repeat request (HARQ) with rate splitting are provided. A first wireless communication device communicates, with a second wireless communication device, a first communication signal including a plurality of information bits. The first wireless communication device determines a number of bits in the plurality of information bits to be repeated in a second communication signal based on channel capacity information. The first wireless communication device communicates, with the second wireless communication device, the second communication signal including the plurality of information bits and a repetition of a subset of the plurality of information bits, where the subset of the plurality of information bits includes the determined number of bits.
