1. A method for wireless communication at a transmitting device, comprising:
identifying a set of information bits to be transmitted to a receiving device via one or more reference signals using a reference signal index modulation scheme, wherein the reference signal index modulation scheme uses one or more activation states of the one or more reference signal transmissions to indicate one or more transmitted bits;
coding the set of information bits to generate an encoded set of bits for transmission using the reference signal index modulation scheme, the encoded set of bits including two or more subsets of encoded bits; and
transmitting the encoded set of bits to the receiving device using the reference signal index modulation scheme.
