BASE STATION FOR GRASPING RECEIVING STATE OF WIRELESS TERMINAL BASED ON DRC SIGNAL TRANSMITTED FROM WIRELESS TERMINAL, AND APPROPRIATELY CONTROLLING DIRECTION OF TRANSMITTING ANTENNA

摘要

PURPOSE: A base station are provided to realize communication of a wireless terminal in an excellent receiving state. CONSTITUTION: An antenna array(1) includes a plurality of antenna elements(11). The antenna array(1) is connected with a base station(2) by connecting each antenna element(11) to a transmitting and receiving wireless circuit part(21). The transmitting and receiving wireless circuit part(21) is formed of transmitting part generating electric waves transmitted to a wireless terminal, and a receiving part amplifying and frequency-converting electric waves received from the antenna array(1) to output the amplified and frequency-converted signal to a wireless modulating and demodulating unit(22). The wireless modulating and demodulating unit(22) relays analog signals processed by the transmitting and receiving wireless circuit part(21) and digital signals processed by a base band signal processor(23). A control unit(50) includes a receiving state acquiring part(51) acquiring a DRC(Data Rate Control bit) signal related to a receiving state of the wireless terminal, and a direction control part(52) converting the direction of the antenna array(1) based on the acquired DRC signal.
