Capability-based modulation of communications between wireless communication devices

An apparatus for wireless communication at a second user equipment (UE), comprising:

• a memory;
• and
• a processor coupled to the memory and configured to cause the apparatus to:
• transmit, to a first UE, a capability message indicating that the second UE is capable of processing one or more types of modulated waveforms;
• monitor for a set of orthogonal frequency division multiplexing symbols that is encoded with a first set of data for an uplink transmission from the first UE to a network entity that is modulated with a second set of data for the second UE according to a type of the one or more types of modulated waveforms capable of being processed by the second UE;
• and
• decode the second set of data modulated with the one or more types of modulated waveforms by processing the set of orthogonal frequency division multiplexing symbols based at least in part on monitoring for the set of orthogonal frequency division multiplexing symbols.

An apparatus for wireless communication at a network entity, comprising:

• a memory;
• and
• a processor coupled to the memory and configured to cause the apparatus to:
• transmit, to each of a first user equipment (UE) and a second UE, an indication of a set of occasions for communicating one or more types of modulated waveforms;
• monitor for a set of orthogonal frequency division multiplexing symbols that is encoded with a first set of data for an uplink transmission from the first UE and that is modulated with a second set of data for the second UE according to a type of one or more types of modulated waveforms capable of being processed by the second UE based at least in part on the indication;
• and
• decode the encoded first set of data by processing the modulated set of encoded orthogonal frequency division multiplexing symbols based at least in part on the monitoring.

A method for wireless communication at a first user equipment (UE), comprising:

• receiving, from a second UE, a capability message indicating that the second UE is capable of processing one or more types of modulated waveforms;
• encoding a set of orthogonal frequency division multiplexing symbols with a first set of data for an uplink transmission to a network entity via a communication link between the first UE and the network entity;
• modulating, based at least in part on the capability message and on the encoding, the set of encoded orthogonal frequency division multiplexing symbols with a second set of data for the second UE according to a type of the one or more types of modulated waveforms capable of being processed by the second UE;
• and
• transmitting the modulated set of encoded orthogonal frequency division multiplexing symbols via the communication link.
