Data Transmission Device of Mobile Terminal, and Mobile Terminal

A mobile terminal, comprising a data transmission apparatus, wherein the apparatus comprises a radio frequency (RF) front end module, a light fidelity (LiFi) front end module, a transceiver coupled to the RF front end module and the LiFi front end module respectively and a baseband protocol processor coupled to a first transceiver,

• wherein the baseband protocol processor is configured to:
• generate wireless fidelity (WiFi) transmission information based on information to be transmitted, control the transceiver to mix the WiFi transmission information to a first frequency and transmit the WiFi transmission information mixed to the first frequency via the RF front end module;
• or
• generate LiFi transmission information based on information to be transmitted, control the transceiver to mix the LiFi transmission information to a second frequency and transmit the LiFi transmission information mixed to the second frequency via the LiFi front end module.

A data transmission apparatus for a mobile terminal, comprising:

• a radio frequency (RF) front end module;
• a light fidelity (LiFi) front end module;
• one or more first transceivers each of which is coupled to the RF front end module and the LiFi front end module, respectively;
• and
• one or more first baseband protocol processors coupled to the one or more first transceivers respectively, wherein each first baseband protocol processor is configured to generate wireless fidelity (WiFi) transmission information or LiFi transmission information based on information to be transmitted, and to control the coupled first transceiver to mix the WiFi transmission information to a frequency specified by the first baseband protocol processor for a WiFi communication mode and transmit the mixed WiFi transmission information via the RF front end module, and to control the coupled first transceiver to mix the LiFi transmission information to a frequency specified by the first baseband protocol processor for a LiFi communication mode and transmit the mixed LiFi transmission information via the LiFi front end module;
• wherein different first baseband protocol processors specify different frequencies for the WiFi communication mode and specify different frequencies for the LiFi communication mode, the single first baseband protocol processor specifies different frequencies for the WiFi communication mode and the LiFi communication mode.
