Abstract: A method for transmitting a control error packet to a wireless power transmitter includes transmitting the control error packet including a control error value to the wireless power transmitter within a first time interval or a second time interval larger than the first time interval, based on a type of a power profile and a version of wireless power transfer standard with which the wireless power receiver and the wireless power transmitter comply. When the version of the wireless power transfer standard is a first version, the wireless power receiver transmits the control error packet within the first time interval. When the version of the wireless power transfer standard is a second version higher than the first version and the type of the power profile is an extended power profile, the wireless power receiver transmits the control error packet within the second time interval.
