Measuring self-interference for full-duplex communications

An apparatus for wireless communication at a first 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 second device, a reference signal over first resources of a first carrier, wherein the first carrier is configured for full-duplex operations for the first device;
• transmit a first signal over second resources that overlap in time with the first resources for receiving the reference signal;
• receive at least a portion of the first signal;
• determine a modulation and coding scheme (MCS) based at least in part on receiving the reference signal and the at least the portion of the first signal;
• and
• communicate with the second device based at least in part on the determined MCS.

• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• receive, from a second device, a reference signal;
• transmit, to the second device, a first indication of a modulation and coding scheme (MCS) for a carrier and a second indication that the MCS is associated with full-duplex communications at the first device;
• and
• communicate with the second device based at least in part on transmitting the first indication of the MCS and the second indication that the MCS is associated with the full-duplex communications at the first device.
