Non-transitory computer readable storage medium, processing device, and base station device for determining parameter when base station device is installed

A processing device for determining a condition for installing each of a plurality of base station devices included in a first radio communication system, the first radio communication system using a same frequency band as and being different from a second radio communication system, the processing device comprising:

• an acquirer structured to acquire, when a signal is transmitted from each of the plurality of base station devices while changing an azimuth angle, interference power of the signal received by a target station included in the second radio communication system for each combination of a base station device and the azimuth angle;
• a definition unit structured to define an azimuth angle range in which the interference power equal to or greater than a threshold is included as a restricted area;
• and
• a determiner structured to determine a direction of a center of a beam of each of the plurality of base station devices so as to prevent the center of the beam of each of the plurality of base station devices from falling within the restricted area,
• wherein
• the direction of the center of the beam of each of the plurality of base station devices is identical to each other by transmitting the beam of each of the plurality of base stations in a same direction.

A base station device comprising:

• a processing device for determining a condition for installing each of a plurality of base station devices included in a first radio communication system, the first radio communication system using a same frequency band as and being different from a second radio communication system, wherein the processing device comprises:
• an acquirer structured to acquire, when a signal is transmitted from each of the plurality of base station devices while changing an azimuth angle, interference power of the signal received by a target station included in the second radio communication system for each combination of a base station device and the azimuth angle;
• a definition unit structured to define an azimuth angle range in which the interference power equal to or greater than a threshold is included as a restricted area;
• and
• a determiner structured to determine a direction of a center of a beam of each of the plurality of base station devices so as to prevent the center of the beam of each of the plurality of base station devices from falling within the restricted area;
• and
• an output unit structured to output information on the direction of the center of the beam determined by the determiner,
• a receiver structured to receive information from the processing device;
• and
• a setter structured to set a direction of a center of a beam on the basis of the information received by the receiver,
• wherein
• the direction of the center of the beam of each of the plurality of base station devices is identical to each other by transmitting the beam of each of the plurality of base stations in a same direction.
