1. A method of interference control for a power transmission unit, PTU, the method comprising:

  • determining, by the PTU, whether the PTU is in an interference environment in which interference of neighboring PTUs occurs; and

    in response to a result of the determination that the PTU is in the interference environment, controlling, by the PTU, at least one of the following communication parameters;

    a time interval of a report signal of a power receiving unit PRU and a time interval of a response signal from the PTU or the neighboring PTU in response to the report signal,wherein a time interval of the response signal from the PTU is different from a time interval of the response signal from the neighboring PTU,wherein the controlling includes;

    determining an interval of each report signal of the PRU based on the number of the neighboring PTUs receiving report signals from the PRU, and transmitting a control signal including information on the interval of each report signal to the PRU.
