1. A method for wireless power transmission, comprising:
receiving a first foreign object status packet and a second foreign object status packet from a wireless power receiver;
transmitting a first foreign object detection indicator including a positive response signal or a negative response signal in response to the first foreign object status packet;
transmitting a second foreign object detection indicator including the positive response signal or the negative response signal in response to the second foreign object status packet;
proceeding to a first subsequent phase of a charging procedure when the first foreign object detection indicator and the second foreign object detection indicator include the positive response signal; or
proceeding to a second subsequent phase of the charging procedure requesting an end of the charging procedure or proceeding to a third subsequent phase of the charging procedure different than the end of the charging procedure when at least one of the first foreign object detection indicator or the second foreign object detection indicator includes the negative response signal,
wherein the first foreign object status packet includes mode information indicating whether or not information on a reference quality factor or a reference peak frequency is included in the first foreign object status packet, and the second foreign object status packet includes mode information indicating whether or not information on a reference quality factor or a reference peak frequency is included in the second foreign object status packet.
