ANTENNA IMPEDANCE MATCHING APPARATUS CAPABLE OF PERFORMING ANTENNA IMPEDANCE MATCH WITH A SIMPLE AND EFFECTIVE METHOD IN A RADIO COMMUNICATIONS SYSTEM AND A METHOD THEREOF

摘要

PURPOSE: An antenna impedance matching apparatus in a radio communications system and a method thereof are provided to effectively use transmission power of an antenna.;CONSTITUTION: A receiver receives power control information. The power control information comprises information for controlling transmission power of a mobile terminal. A matching controller (308) produces matching control information for antenna impedance match based on the power control information. An antenna matching unit (306) performs the antenna impedance match according to the produced matching control information.;COPYRIGHT KIPO 2013;[Reference numerals] (300) Baseband processing unit; (302) RF unit; (304) Power amplifying unit; (306) Antenna matching unit; (308) Matching controller
