1. A power transmission device, comprising:
- a communication unit configured to communicate with a power receiving device;
a power transmitting unit configured to transmit an amount of power wirelessly to the power receiving device; and
a controller unit configured to;
send a request, through the communication unit, for information that indicates a power reception capability of the power receiving device that includes at least a transmission type and receive a response that bears power reception capability information corresponding to the request;
generate a randomized parameter for the power receiving device based on the received power reception capability information that includes the transmission type; and
determine the amount of power to be transmitted to the power receiving device based on the received power reception capability information that includes the transmission type, wherein the power is transmitted to the power receiving device based on the randomized parameter.

Abstract
A power transmission device includes a communication unit that transmits a power capability information transmission request, receives power capability information in response to the power capability information transmission request, and transmits randomized parameter information by a communication channel. The power transmission device also includes a processing unit that produces the randomized parameter information, based on the power capability information. Further, the power transmission device includes a power transmission unit that wirelessly transmits power based on the randomized parameter information.
