This publication describes systems and techniques for power backoff to address intermodulation distortion and harmonic distortion. A wireless communication device, which engineers often refer to as user equipment (UE), includes power backoff logic and a transmit backoff table. In a dual-connectivity environment with operating conditions known to result in potential distortion, a processor of the UE looks up a power backoff level in the transmit backoff table and directs a transceiver to back off the transmit power to mitigate intermodulation distortion or harmonic distortion. The UE can use similar systems and techniques to address distortion issues in carrier aggregation or multi-connectivity environments.
