Title:
WIRELESS CHARGING COMMUNICATION METHOD, APPARATUS AND DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2020/237820
Kind Code:
A1
Abstract:
Disclosed are a wireless charging communication method, apparatus and device, and a storage medium, belonging to the technical field of wireless charging. The method comprises: if emergency data needs to be transmitted during a wireless charging process, sending a data packet to a wireless power sending device by means of in-band communication; and if non-emergency data needs to be transmitted during the wireless charging process, sending a data packet to the wireless power sending device by means of out-of-band communication, wherein the transmission delay requirement of the emergency data is higher than the transmission delay requirement of the non-emergency data. In the present application, when the non-emergency data needs to be transmitted, the out-of-band communication means with a relatively good communication quality is used to send the data packet with a relatively low transmission delay requirement, thereby facilitating an increase in the demodulation success rate of the data packet; and when the emergency data needs to be transmitted, the in-band communication means is used to send the data packet with a relatively high transmission delay requirement, thereby ensuring that the wireless power sending device can process, in a timely manner, the data packet in the case that the emergency data needs to be transmitted.
