METHOD OF RELAY COMMUNICATING IN MAGNETIC FIELD AREA

摘要

A relay communication method in a magnetic field area, in accordance with the present invention, is performed by a wireless power coordinator which manages a magnetic field communication network. The relay communication method comprises the steps of: (a) forming a super frame structure by a time division multiple access (TDMA) method; (b) allocating one of time slots, constituting the super frame structure, to one of a wireless power repeater or a plurality of wireless charging nodes, which can be connected to the wireless power coordinator; (c) forming an assigned time slot with a separate super frame for relay when the wireless power repeater is assigned a time slot; and (d) wirelessly transmitting power to a wireless charging node, which is more adjacent to the wireless power repeater than the wireless power coordinator, among the wireless charging nodes through the composed super frame for relay.
