Patent ID: 8489036

Claim:
A mobile device for receiving power from a battery and transmitting and receiving a radio frequency signal through first and second transmitting units in a radio communication system, comprising: control means for controlling transmission/receipt of the radio frequency signal and controlling transmission/receipt diversity; receipt adjusting means for controlling receipt of the radio frequency signal and controlling receipt diversity under control of the control means; first radio frequency signal receiving means for converting the radio frequency signal received through the first transmitting unit into a baseband signal to be transmitted to the control means under receipt control of the receipt adjusting means; second radio frequency signal receiving means for converting the radio frequency signal received through the second transmitting unit into a baseband signal to be transmitted to the control means under receipt diversity control of the receipt adjusting means; transmission diversity adjusting means for controlling transmission diversity under control of the control means; and radio frequency signal transmitting means for converting the baseband signal transmitted from the control means into a radio frequency signal to be transmitted to the first transmitting unit and transmitting the radio frequency signal to the second transmitting unit under transmission diversity control of the transmission diversity adjusting means, wherein the receipt adjusting means comprises: a first receipt adjustor for receiving power supplied from the battery and supplying driving power source to the first radio frequency signal receiving means under control of the control means; and a second receipt adjustor for receiving power supplied from the battery and supplying driving power source to the second radio frequency signal receiving means under control of the control means.
