Abstract
Methods, systems, and devices for wireless communication are described. A user equipment (UE) may mitigate self-interference and intermodulation products caused by communicating over two carriers in order to improve measurements of a third carrier. The UE may determine a measurement configuration to determine the quality of the third carrier. The measurement configuration may include identifying time periods with no scheduled uplink transmissions, time periods with a transmit power below a power threshold, time periods with frequency locations with an expected lower intermodulation interference, or time periods with a scheduled reference signal transmission (e.g., a synchronization signal (SS) block). The UE may also reduce a transmit power for a time period or drop a scheduled uplink transmission in order to perform more accurate measurements on the third carrier. In some cases, a base station may schedule a measurement gap for the UE to perform the measurements.
