Claim 28:
29. A method for wireless communication at a first device, comprising:
selecting a first index modulation scheme or a second index modulation scheme for encoding a set of reference signal resources to include a second subset of information bits based on values associated with a first subset of information bits wherein the first index modulation scheme and the second index modulation scheme are different types of multi-mode reference signal index modulation schemes, and wherein the set of reference signal resources convey a set of information bits to a second device via one or more reference signals, and wherein the set of information bits comprises the first subset of information bits and the second subset of information bits;
encoding the set of information bits by applying, to a set of reference signals to be transmitted using the set of reference signal resources, the first index modulation scheme for a first value of the first subset of information bits and the second index modulation scheme for a second value of the first subset of information bits, wherein a respective bit value associated with the second subset of information bits is encoded based on a respective bit value associated with the first subset of information bits; and
transmitting, to the second device, the encoded set of information bits.
