FIELD: electrical engineering.
SUBSTANCE: versions suggest a method, a device and a communication equipment for wireless charging, as well as a data medium related to the field of wireless charging. Method comprises: transmitting a data packet to a wireless power transmission device using in-band communication if urgent data are to be transmitted during wireless charging; and transmitting the data packet to the wireless power transmission device using the out-of-band communication, if non-urgent data should be transmitted during wireless charging; wherein requirements to delays of transfer of urgent data are higher than requirements to delays of transfer of non-urgent data. In the present invention, when it is necessary to transmit non-urgent data having less stringent transmission delay requirements, for transmitting data packets with low transmission delay requirements, using out-of-band communication, which provides higher quality of communication, which increases probability of successful demodulation of data packets; and data packets with higher requirements to transmission delays are transmitted using in-band communication, when it is necessary to transmit urgent data.
EFFECT: technical result consists in timely processing of a data packet by a wireless power transmission device when transmitting urgent data.
