초록 ▼

A method for controlling inter-cell interference (ICI) in a mobile communication system by transmitting uplink control information from a base station in a home cell to a terminal of a neighboring cell based on ICI amount information measured at the base station. The ICI control method includes receiving an uplink signal at a base station and extracting inter-cell interference amount information from the uplink signal, generating uplink control information based on the extracted inter-cell interference amount information, and transmitting the uplink control information to a terminal in a neighboring cell. The terminal schedules an uplink resource including selecting frequency bands for an uplink signal by referring to the uplink control information.

1. A method for scheduling an uplink resource in a mobile communication terminal located in a first cell, comprising: receiving a first uplink control information from a first base station in the first cell;receiving a second uplink control information from a second base station in a second cell neighboring the first cell; andcontrolling a transmission signal power for each frequency band of an uplink signal by referring to the first and the second uplink control information of the first and the second base station. 2. A method for scheduling an uplink resource in a mobile communication terminal located in a first cell, comprising: receiving a first uplink control information from a first base station in the first cell;receiving a second uplink control information form a second base station in a second cell neighboring the first cell; andcontrolling a transmission signal power for each frequency band of an uplink signal by referring only to the first uplink control information of the first base station. 3. A method for scheduling an uplink resource in a mobile communication terminal located in a first cell, comprising: receiving a first uplink control information from a first base station in the first cell;receiving a second uplink control information from a second base station in a second cell neighboring the first cell; andcontrolling a transmission signal power for each frequency band of an uplink signal by referring only to the second uplink control information of the second base station. 4. A method for scheduling an uplink resource in a mobile communication terminal located in a first cell, comprising: receiving a second uplink control information from only a second base station in a second cell neighboring the first cell;controlling a transmission signal power for each frequency band of an uplink signal by referring only to the second uplink control information of the second base station; andtransmitting an uplink signal to only a first base station of the first cell.
