s301, transmitting a first optical signal corresponding to the uplink data signal to the LiFi device, wherein the first optical signal is used for indicating the LiFi device to convert the first optical signal into a first electric signal and sending the first electric signal to a base station.

It can be appreciated that, when the terminal performs network communication, a connection needs to be established with the base station so that the terminal can transmit signals to the base station or receive signals from the base station. When the terminal needs to send a signal to the base station, a first optical signal corresponding to the uplink data signal may be transmitted to the LiFi device first. Specifically, the uplink data signal may be a signal to be sent to the base station by the terminal, and may be various control signals sent by the processor or a data signal carrying information, where the terminal may be provided with a LiFi device to implement a LiFi function, that is, the terminal converts the uplink data signal into a first optical signal through the set LiFi device, and then transmits the first optical signal through the LiFi device.

Optionally, the steps S301 and S302 may be performed separately in the terminal, that is, the terminal only executes the step S301, and then only uploads the uplink data signal, or the terminal only executes the step S302, and then only downloads the downlink data signal, and the steps S301 and S302 may be performed simultaneously in the terminal, that is, the terminal may simultaneously upload the uplink data signal and simultaneously download the downlink data signal.
