Control apparatus, method, program, and recording medium

A method comprising:

• obtaining information related to a first schedule for coordinated control between a first radio base station and a second radio base station;
• estimating a communication quality between the first radio base station and a first terminal apparatus, with a first quality correction value based on the information related to the first schedule, upon determining a communication interference between the first radio base station and the first terminal apparatus has been suppressed by a signal from the second radio base station, or with a second quality correction value based on the information related to the first schedule, upon determining the communication interference has not been suppressed by the signal;
• performing control related to a second schedule for radio communication performed with a first terminal apparatus by the first radio base station, based on the communication quality;
• updating by increasing the first quality correction value upon determining there is no second terminal apparatus to which radio resources have been allocated by the second radio base station, or upon determining there is the second terminal apparatus to which radio resources have been allocated by the second radio base station and the information related to the first schedule has been received, in the case where the one or more processors has received notification from the first terminal apparatus about success of reception, of a data that has been transmitted from the first radio base station to the first terminal apparatus;
• updating by increasing the second quality correction value upon determining there is the second terminal apparatus to which radio resources have been allocated by the second radio base station and the information related to the first schedule has not been received, in the case where the one or more processors has received notification from the first terminal apparatus about success of reception, of the data;
• updating by decreasing the first quality correction value upon determining there is no second terminal apparatus to which radio resources have been allocated by the second radio base station, or upon determining there is the second terminal apparatus to which radio resources have been allocated by the second radio base station and the information related to the first schedule has been received, in the case where the one or more processors has received a notification from the first terminal apparatus about reception error from the first terminal apparatus, of the data;
• and
• updating by decreasing the second quality correction value upon determining there is the second terminal apparatus to which radio resources have been allocated by the second radio base station and the information related to the first schedule has not been received, in the case where the one or more processors has received a notification from the first terminal apparatus about reception error from the first terminal apparatus, of the data.

A computer-readable non-transitory recording medium having recorded thereon a program that causes a processor to:

• obtain information related to a first schedule for coordinated control between a first radio base station and a second radio base station;
• estimate a communication quality between the first radio base station and a first terminal apparatus, with a first quality correction value based on the information related to the first schedule, when a communication interference between the first radio base station and the first terminal apparatus has been suppressed by a signal from the second radio base station, or with a second quality correction value based on the information related to the first schedule, when the communication interference has not been suppressed by the signal;
• perform control related to a second schedule for the first radio base station to perform radio communication with a first terminal apparatus, based on the communication quality,
• update by increasing the first quality correction value when there is no second terminal apparatus to which radio resources have been allocated by the second radio base station, or when there is the second terminal apparatus to which radio resources have been allocated by the second radio base station and the information related to the first schedule has been received, in the case where the one or more processors has received notification from the first terminal apparatus about success of reception, of a data that has been transmitted from the first radio base station to the first terminal apparatus;
• update by increasing the second quality correction value when there is the second terminal apparatus to which radio resources have been allocated by the second radio base station and the information related to the first schedule has not been received, in the case where the one or more processors has received notification from the first terminal apparatus about success of reception, of the data;
• update by decreasing the first quality correction value when there is no second terminal apparatus to which radio resources have been allocated by the second radio base station, or when there is the second terminal apparatus to which radio resources have been allocated by the second radio base station and the information related to the first schedule has been received, in the case where the one or more processors has received a notification from the first terminal apparatus about reception error from the first terminal apparatus, of the data;
• and
• update by decreasing the second quality correction value when there is the second terminal apparatus to which radio resources have been allocated by the second radio base station and the information related to the first schedule has not been received, in the case where the one or more processors has received a notification from the first terminal apparatus about reception error from the first terminal apparatus, of the data.
