If you are using timed commands and if you can verify that the tx-to-rx synchronization is consistent every time, perhaps you could measure the leakage signal (with attenuators connected to the RF ports) and then simply subtract this signal from your over-the-air measurements. This method of leakage cancellation can change over time as the device heats up so you may need to periodically perform this calibration. Rob
