Cooperative wireless power signal transmission method and device
First Claim
1. A wireless power transmission method in which power is wirelessly transmitted to terminals in a wireless communication system, the wireless power transmission method comprising:
- determining one or more nodes to transmit power transmission signals to a specific terminal, from among a plurality of nodes;
matching phase synchronization of the power transmission signals between the one or more nodes with each other; and
allowing the one or more nodes to transmit the power transmission signals of which the phase synchronization has been matched to the specific terminal,wherein the one or more nodes transmit the power transmission signals of which the phase synchronization has been matched for a period when the specific terminal is in an idle mode.

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.
