A terminal and a communication method thereof, a base station controller and a control method thereof, and a wireless communication system and a method thereof are provided. The wireless communication system includes a terminal, a controller, and at least one base station. The terminal (200) has an array antenna and searches for neighbor base stations (100). The controller (300) determines an active set for multi-cooperative transmission/reception with respect to the terminal among searched neighbor base stations, and schedules beam transmission of each base station included in the determined active set. The at least one base station performs transmission/reception with the terminal using beam-forming in an ultra high frequency band, and provides resource information regarding uplink/downlink of each base station included in the active set to the terminal based on the scheduling by the controller.
