    Abstract: Methods and apparatus are provided for detecting a non-intended object of power reception by a power transmitter. Power transmission for communication is performed, when the load change is sensed that has a value greater than or equal to a predetermined threshold. It is determined whether a subscription request, for subscribing to a network is received within a predetermined time period. The power transmission for communication is stopped when the subscription request is not received within the predetermined time period. Power is transmitted to a power receiver that has transmitted the subscription request, when the subscription request is received within the predetermined time period. It is determined whether a leakage power value exceeds an allowable range, when the power state report is received from the power receiver. The transmission of the power to the power receiver is stopped, when the leakage power value exceeds the allowable range.

    Abstract: A method of transmitting a signal by a wireless power transmitter in a wireless charging system, wireless power transmitter, and a wireless power receiver are provided. The method includes receiving, from a wireless power transmitter, a first beacon power for a first duration time in every first period; receiving, from the wireless power transmitter, a second beacon power for a second duration time in every second period; if the wireless power receiver determines that an extension of the second beacon power is required, generating load changes while receiving the second beacon power for the second duration time; in response to the generated load changes, continually receiving, from the wireless power transmitter, the second beacon power until a predetermined third duration time, wherein the predetermined third duration time is determined before the second beacon power is transmitted by the wireless power transmitter; and transmitting an advertisement signal to the wireless power transmitter while receiving the second beacon power for the predetermined third duration time.
