Abstract
Disclosed are a method and device for cooperatively sending and receiving power wirelessly. Wireless power charging coverage at the level of data signal transmission can be ensured by establishing one or more modes for transmitting, to a specific terminal, a power transmission signal from any of a plurality of nodes which is (are) not engaged in data transmission, and by matching the phase synchronization of the power transmission signal between the one or more nodes and then transmitting, to the specific terminal, a power transmission signal of which the phase synchronization has been matched by means of the one or more modes.
