Techniques for managing peak-to-average power ratio

An apparatus for wireless communication at a second device, comprising:

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• receive, from a first device, a signal;
• determine a sequence associated with the signal;
• decode the sequence based at least in part on an index demodulation scheme to identify a first subset of information bits of a set of information bits encoded in the signal, a second subset of information bits of the set of information bits encoded in the signal, and a third subset of bits of the set of information bits encoded in the signal based at least in part on the sequence;
• and
• discard the third subset of information bits based at least in part on the decoding.

A method for wireless communication at a first device, comprising:

• generating a set of information bits to convey to a second device via an index modulation scheme, the set of information bits comprising a first subset of information bits and a second subset of information bits;
• generating a third subset of information bits based at least in part on a linear coding scheme;
• inserting the third subset of information bits within the first subset of information bits or the second subset of information bits;
• encoding the set of information bits based at least in part on the inserting;
• and
• transmitting, to the second device, a signal comprising the encoded set of information bits.
