Disclosed in an embodiment of the present invention are a mobile communication terminal and signal transmission method of the mobile communication terminal. The mobile communication terminal comprises a signal output module, a main antenna module, a diversity antenna module, an acquisition module, a control module and a radio-frequency switching module; the acquisition module is used to acquire the transmission power P1 of a transmission signal when the signal output module generates the transmission signal and transmits the signal via the main antenna module, and to acquire the transmission capacity of the main antenna module and the diversity antenna module when the transmission power P1 is greater than a first preset value; the control module is used to output a corresponding control signal to the radio-frequency switching module according to the transmission capacity of the main antenna module and the diversity antenna module; and, according to the control signal, the radio-frequency switching module is used to control the output module to connect to the main antenna module or the diversity antenna module. |
