1. An interference control method of a power transmitting unit (PTU), the method comprising:
- determining whether the PTU is in an interference environment in which interference by a neighbor PTU occurs; and
controlling an interval of a report signal from the power receiving unit (PRU) and an interval of a response signal from the power transmitting unit (PTU) or the neighbor PTU responding to the report signal in response to determining the PTU is in the interference environment.

Abstract
An interference control method of a power transmitting unit (PTU) includes determining whether the PTU is in an interference environment in which interference by a neighbor PTU occurs, and controlling a communication parameter of either one or both of the neighbor PTU and a power receiving unit (PRU) in response to a result of the determining being that the PTU is in the interference environment.

18. A power transmitting unit (PTU) comprising:
-
an interference environment determiner configured to determine whether the PTU is in an interference environment in which interference by a neighbor PTU occurs; and a communication parameter controller configured to control an interval of a report signal from the PRU and an interval of a response signal from the PTU or the neighbor PTU responding to the report signal in response to the interference environment determiner determining that the PTU is in the interference environment.

19. An interference control method of a power transmitting unit (PTU), the method comprising:
-
transmitting power by the PTU to a power receiving unit (PRU); determining whether a neighbor PTU is interfering with the PTU or has a potential to interfere with the PTU; and controlling, an interval of a report signal from the PRU and an interval of a response signal from the PTU or the neighbor PTU responding to the report signal in response to determining the neighbor PTU is interfering with the PTU or has a potential to interfere with the PTU. - View Dependent Claims (20, 21)
