Abstract
A wireless power transmitter, includes a power conversion unit configured to form a wireless power for power transmission; and a power transmission control unit configured to control the power conversion unit to detect a collision between a first packet generated by a first wireless power receiver and a second packet generated by a second wireless power receiver in a same time slot, and control the power conversion unit to transmit information indicating the collision to the first wireless power receiver and the second wireless power receiver.
Claims13
A wireless power transmitter, comprising:
- a power conversion unit configured to form a wireless power for power transmission;
- and
- a power transmission control unit configured to:
- control the power conversion unit to detect a collision between a first packet generated by a first wireless power receiver and a second packet generated by a second wireless power receiver in a same time slot, and
- control the power conversion unit to transmit information indicating the collision to the first wireless power receiver and the second wireless power receiver.
A wireless power receiver, comprising:
- a power receiving unit configured to receive a wireless power from a wireless power transmitter;
- and
- a power reception control unit configured to:
- control the power receiving unit to generate a first packet for the wireless power transmitter, and
- control the power receiving unit to receive information indicating a collision between the first packet and a second packet from another wireless power receiver is detected in a same time slot from the wireless power transmitter.
A method of avoiding signal collision by a wireless power receiver, the method comprising:
- receiving a wireless power from a wireless power transmitter;
- generating a first packet for the wireless power transmitter, and
- receiving information indicating a collision between the first packet and a second packet from another wireless power receiver is detected in a same time slot from the wireless power transmitter.
