    摘要： A base station is capable of performing 4-beamforming using Radio Units (RU), each having two paths in a wireless communication system. The base station includes a Digital Unit (DU), a first RU, and a second RU. The DU performs a mutual conversion function between an information bit line and a digital signal, calculates beamforming coefficients for 4-beamforming, and performs the 4-beamforming using the beamforming coefficients. The first RU has two Radio Frequency (RF) paths, extracts a clock signal from a digital signal from the DU, and provides the clock signal to the second RU. The second RU has two RF paths and operates according to the clock signal provided from the first RU.
