Wireless Communication Apparatus and Transmission Control Method Thereof

The transmission control method of the wireless communication apparatus according to 1, further comprising:

• a modulation class recognizing step for recognizing whether or not the modulation class is the predetermined low modulation class or a lower modulation class when communication is performed at the communication speed lower than the predetermined value;
• and
• a modulation class changing step for changing the modulation class at least to the predetermined low modulation class when the modulation class is over the predetermined low modulation class as a result of recognition,
• wherein the amplification path selection step is executed after execution of the modulation class changing step.

A wireless communication apparatus for wireless communication using an adaptive modulation scheme comprising:

• at least two amplification paths having different power consumption and capable of amplifying a transmission signal;
• a selection unit for selecting one of the at least two amplification paths;
• and
• a control unit for controlling the selection unit to select one of the amplification paths and the transmission signal to be amplified in the selected amplification path in accordance with operational condition of the wireless communication apparatus when communication is performed at a communication speed lower than a predetermined value in a predetermined low modulation class.
