Abstract

A method, performed by a wireless power transmitter, for transmitting wireless power in a wireless power transmission system, comprises: receiving, from at least one wireless power transmitter, a configuration packet notifying the availability of out of band (OB) in a configuration phase; transmitting, to the at least one wireless power receiver, a capability packet notifying the availability of the OB in a negotiation phase; and establishing a Bluetooth low energy (BLE) connection with the at least one wireless power receiver on the basis of the configuration packet and the capability packet, wherein the BLE connection is a connection based on a BLE isochronous (ISO) channel, and through the BLE connection, the at least one wireless power transmitter exchanges at least one piece of power control data with the at least one wireless power receiver in at least one sub-event included in an interval of the BLE ISO channel.
