摘要： A method for managing radio resources for an uplink and a downlink in a wireless communication system is provided. The method for managing radio resources may be applied to a system based on a heterogeneous cell deployment scenario. The heterogeneous cell deployment scenario implies that a plurality of cells coexist in the wireless communication system, and transmit power, processing capacity, and/or cell coverage are different from one cell to another. In the method for managing radio resources, a mobile station included in the wireless communication system establishes an uplink and a downlink with the same base station. In addition, an asymmetric management scheme is used in which a radio resource management scheme used for the uplink is different from a radio resource management scheme used for the downlink. Accordingly, each mobile station can use a different optimal radio resource management scheme for the uplink and the downlink, each mobile station and link can be effectively controlled, and usage efficiency of radio resources can be improved.
