Abstract: An apparatus and a method for performing handover between heterogeneous communication methods. A wireless power transmission apparatus and reception apparatus can indicate whether to support out-band communication thereof on the basis of an out-band flag. The wireless power transmission apparatus can request the wireless power reception apparatus to start a handover by using a bit pattern requesting the handover. The handover procedure to out-band may be performed in a negotiation phase or may be performed in a separate handover phase. Information for establishing an out-band communication connection can be transmitted from the wireless power reception apparatus to the wireless power transmission apparatus through in-band communication. Also, even after the handover to the out-band is completed, it is possible to periodically or intermittently perform the in-band communication in a power transmission phase to detect a swap of the wireless power reception apparatus.

Abstract: A wireless power transmission apparatus includes a shielding plate, a transmission coil on the shielding plate, and a shielding member disposed on the shielding plate and configured to surround the transmission coil. The shielding plate may shield a magnetic field formed to a lower side of the transmission coil. The shield member can offset the magnetic field formed on the side of the transmission coil. Thus, the embodiment can minimize EMI or EMF caused by the magnetic field formed on the lower side and the side of the transmission coil.
