30. A method for wireless communication at a first device, comprising:
receiving, from a second device, a reference signal that includes a sequence; and
decoding, from the reference signal, a first subset of information bits of a set of information bits encoded in the reference signal and a second subset of information bits of the set of information bits encoded in the reference signal based on the sequence and on values associated with the first subset of information bits, the first subset of information bits encoded in the reference signal based on the sequence corresponding to a first group of sequences or a second group of sequences and the second subset of information bits encoded in the reference signal based on a mapping between the sequence and one or more values of the second subset of information bits, wherein a respective bit value associated with the second subset of information bits is decoded based on a respective bit value associated with the first subset of information bits.
