Abstract: A base station and an antenna selection method and apparatus thereof are provided. The antenna selection method includes receiving signals through multiple antennas, measuring channel information from the received signals, determining antennas having received signals whose channel information is higher than or equal to a preset threshold, and combining and processing the signals having received through the determined antennas. As a result, the base station may select an antenna enabling effective uplink communication with a user equipment among multiple antennas.
