Method for implementing diversity in mobile telephone and mobile telephone incorporating the same

A mobile communication terminal, comprising:

• a memory unit for storing a reference value of an amount of power remaining in a power supply device for activation of a transmission/reception diversity function;
• a plurality of RF transmission/reception units each including an antenna, a duplexer for separating RF transmission signals and RF reception signals, an RF reception unit for receiving RF signals from a base station, and an RF transmission unit for transmitting RF signals;
• a control unit for deactivating a transmission/reception diversity function when an amount of power remaining in a power supply device is smaller than the reference value stored in the memory unit, and activating the transmission/reception diversity function when the amount of power remaining in the power supply device is equal to or larger than the reference value stored in the memory;
• and
• a transmission/reception diversity control unit for applying power to all of the RF transmission/reception units when the activation of the transmission/reception diversity function is requested by the control unit, and applying power to one of the RF transmission/reception units and cutting off supply of power to at least one remaining RF transmission/reception unit when the deactivation of the transmission/reception diversity function is requested by the control unit.
