Electronic device and method for scheduling

A first base station performing scheduling over a wireless communication network including the first base station and a second base station, the first base station comprising:

• a receiver for receiving first channel status information (CSI) measured by at least one user equipment (UE) positioned in coverage of the first base station and second CSI measured by at least one UE positioned in coverage of the second base station;
• and
• at least one processor configured to:
• determine a first transmission rate for any one of the at least one UE positioned in the coverage of the first base station and a second transmission rate for any one of the at least one UE positioned in the coverage of the second base station, when data coding for interference cancellation is not used, based on the first CSI and the second CSI,
• determine a third transmission rate for a first UE among the at least one UE positioned in the coverage of the first base station and a fourth transmission rate for a second UE among the at least one UE positioned in the coverage of the second base station, when the data coding for interference cancellation is used, based on the first CSI and the second CSI, and
• perform scheduling to allow the first UE to use the data coding for the interference cancellation based on the first transmission rate through the fourth transmission rate,
• wherein, when the sum of the first transmission rate and the second transmission rate is smaller than the sum of the third transmission rate and the fourth transmission rate, the at least one processor is further configured to perform the scheduling so that the first UE uses the data coding for the interference cancellation.

A core unit controlling a first base station and a second base station, the core unit comprising:

• a receiver for receiving first channel status information (CSI) measured by at least one user equipment (UE) positioned in coverage of the first base station and second CSI measured by at least one UE positioned in coverage of the second base station;
• and
• at least one processor configured to:
• determine a first transmission rate for any one of the at least one UE positioned in the coverage of the first base station and a second transmission rate for any one of the at least one UE positioned in the coverage of the second base station, when data coding for interference cancellation is not used, based on the first CSI and the second CSI,
• determine a third transmission rate for a first UE among the at least one UE positioned in the coverage of the first base station and a fourth transmission rate for a second UE among the at least one UE positioned in the coverage of the second base station, when the data coding for interference cancellation is used, based on the first CSI and the second CSI, and
• control the first base station and the second base station to allow the first UE and the second UE to use the data coding for the interference cancellation based on the first transmission rate through the fourth transmission rate,
• wherein, when the sum of the first transmission rate and the second transmission rate is smaller than the sum of the third transmission rate and the fourth transmission rate, the at least one processor is further configured to perform the control so that the first UE and the second UE use the data coding for the interference cancellation.
