Methods and apparatuses for transmitting charging power wirelessly are provided. One implementation includes an apparatus for transmitting charging power wirelessly to a vehicle. The apparatus comprises a transmit circuit configured to transfer wireless charging power to the vehicle via a wireless field. The apparatus comprises a controller configured to detect transmission of a wireless vehicle signal having a transmission period and indicative of operation of a vehicle communication system. The controller is configured to cause the transmit circuit to reduce a level of charging power within a first portion of the transmission period. A second, remaining portion of the transmission period is of sufficient duration for allowing identification of the wireless vehicle signal by a receiver of the wireless vehicle signal. The wireless vehicle signal comprises a plurality of pulses. At least one pulse is transmitted within the first portion. The remaining pulses are transmitted within the second, remaining portion.
