Abstract: A method and a system for operating a frame in a mobile communication system are provided to reduce power consumption by scheduling a mobile station in consideration of the state of the mobile station. A frame is composed of an uplink sub frame and a downlink sub frame. Each of the uplink and down link sub frames has a plurality of zones. A base station confirms at least one of the channel state of the mobile station, a communication support state between heterogeneous networks, a load state of the base station, and the cell resource state(302). The base station determines whether the mobile station transmits or receives the signal through a part of zones based on at least one confirmed state(304). If the mobile station transmits or receives the signal through the part of zones, the base station transmits the control information to the mobile station(306). The control information indicates the zone which is used for the signal transmission and reception.
