Abstract

An apparatus for forming a beam in a base station is provided and includes a plurality of channel cards for processing and outputting signals to be transmitted to each channel; a signal synthesizer / distributor for synthesizing the signals from the channel cards and compensating phases of the signals; a channel controller for controlling beams of the signals from the signal synthesizer / distributor according to a demand of a mobile communication terminal and outputting the controlled beam signals; a middle frequency generating block for receiving the signals from the channel controller and synthesizing the signals in each frequency to generate middle frequency signals; a transmitter for converting the middle frequency signals received from the middle frequency generating block into signals in a transmitting band; an RFB for amplifying the signals from the transmitter into signals in an output band and controlling phases of transmitting and receiving signals; and an antenna connection block for switching the signals to corresponding antennas of the RFB so that beams can be generated.

Description

technical field [0001] The present invention relates to base station equipment in a mobile communication system, and more particularly to base station equipment for increasing the efficiency of a base station to expand system capacity and service quality. Background technique [0002] Generally, base stations of a mobile communication system comprise a radio environment, wherein each base station consists of a unit. In addition, each base station consists of a different radio environment, allowing them to receive radio users, depending on the structure and shape of the base stations. There are many different types of base stations, such as sectored base stations and omni-directional base stations. The sector base station has three sectors divided into 120 areas with respect to the base station at the center of a circle. Each zone includes equipment such as antennas. In addition, sectored base stations are classified into base stations using 3FA and ...
