Abstract
Embodiments of this application disclose an NFC-based communication method, an apparatus, and a system. In the NFC-based communication method, an electronic device works in an NFC reader/writer mode and performs an NFC communication process with an NFC tag. When failing to perform the NFC communication process, the electronic device may adjust a currently used radio frequency parameter, and re-perform the NFC communication process with the NFC tag by using an adjusted radio frequency parameter.
Claims21
1-26. (canceled)
A communication method comprising:
- performing, by an electronic device supporting near field communication (NFC) and operating in an NFC reader/writer mode, an NFC communication process between the electronic device and an NFC tag using a first radio frequency parameter;
- and
- performing, by the electronic device in the NFC reader/writer mode, the NFC communication process again using a second radio frequency parameter when a preset condition is met, wherein the second radio frequency parameter is different from the first radio frequency parameter;
- and
- wherein the first radio frequency parameter and the second radio frequency parameter each comprise one or more of following:
- transmit power of sending a radio frequency signal by the electronic device, sensitivity of receiving a radio frequency signal by the electronic device, a modulation mode used during load modulation, a waveform of a carrier, an amplitude of the carrier, a phase of the carrier, or a frequency of the carrier.
An electronic device, wherein the electronic device supports near field communication (NFC), and the electronic device comprises a non-transitory memory, an NFC chip, and one or more processors;
- and the memory is coupled to the one or more processors, the memory is configured to store computer program code, the computer program code comprises computer instructions, and the one or more processors invoke the computer instructions to cause the electronic device to perform:
- performing, when operating in an NFC reader/writer mode, an NFC communication process between the electronic device and an NFC tag using a first radio frequency parameter;
- and
- performing the NFC communication process again in the NFC reader/writer mode using a second radio frequency parameter when a preset condition is met, wherein the second radio frequency parameter is different from the first radio frequency parameter;
- and
- wherein the first radio frequency parameter and the second radio frequency parameter each comprise one or more of following:
- transmit power of sending a radio frequency signal by the NFC chip, sensitivity of receiving a radio frequency signal by the NFC chip, a modulation mode used during load modulation, a waveform of a carrier, an amplitude of the carrier, a phase of the carrier, or a frequency of the carrier.
