Claim 5:
6. A power reception apparatus comprising a controller that controls a power receiver that receives a power transmission beam emitted from a power transmission apparatus, the controller comprising a processor and a memory with instructions thereon, wherein the instructions upon execution by the processor, cause the processor to:
transmit, to the power transmission apparatus, feedback information on a result of reception of a first power transmission beam emitted from the power transmission apparatus in the power receiver and on a power receiving capability in the power receiver, and
after transmission of the feedback information, the power receiver receiving, from the power transmission apparatus, a second power transmission beam having a power level higher than that of the first power transmission beam,
the power receiving capability including a minimum value and a maximum value of an input power range of the power receiver, and
wireless power transmission by the power transmission apparatus using an electromagnetic wave having a frequency equal to or higher than that of a microwave, and wherein
the second power is determined such that a reception power in the power receiver due to the second power transmission beam falls within the input power range.
