Terminal apparatus, base station apparatus, control method, and computer-readable storage medium for suppressing influence of interference on communication in adjacent frequency band

Abase station apparatus that belongs to a first communication system that uses a first frequency band, comprising:

• one or more processors;
• and
• one or more memories that store a computer-readable instruction for causing, when executed by the one or more processors, the one or more processors to function as:
• a notification unit configured to notify a terminal apparatus of setting information indicating setting of measurement in a second frequency band that is different from the first frequency band and is used for a second communication system,
• a receiving unit configured to receive a result of measurement on a predetermined signal transmitted from another base station apparatus that belongs to the second communication system, the measurement having been performed by the terminal apparatus based on the setting information, and
• a scheduling unit configured to determine, based on the result of the measurement, whether or not to allow the terminal apparatus to transmit a signal using predetermined time resources and predetermined frequency resources included in the first frequency band, and perform scheduling of communication with the terminal apparatus based on the determination.

A control method that is executed by a terminal apparatus, comprising:

• obtaining, from a first base station apparatus that belongs to a first communication system that uses a first frequency band, setting information indicating setting of measurement in a second frequency band that is different from the first frequency band and is used for a second communication system;
• performing measurement of a predetermined signal transmitted from a second base station apparatus that belongs to the second communication system, based on the setting information;
• notifying the first base station apparatus of a result of the measurement;
• and
• communicating with the first base station apparatus in accordance with scheduling performed by the first base station apparatus based on the result of the measurement.

A control method that is executed by a base station apparatus that belongs to a first communication system that uses a first frequency band, comprising:

• notifying a terminal apparatus of setting information indicating setting of measurement in a second frequency band that is different from the first frequency band and is used for a second communication system;
• receiving a result of measurement on a predetermined signal transmitted from another base station apparatus that belongs to the second communication system, the measurement having been performed by the terminal apparatus based on the setting information;
• and
• determining, based on the result of the measurement, whether or not to allow the terminal apparatus to transmit a signal using predetermined time resources and predetermined frequency resources included in the first frequency band, and performing scheduling of communication with the terminal apparatus based on the determination.

A non-transitory computer-readable storage medium that stores a program for causing a computer included in a terminal apparatus to execute a control method, wherein the control method comprises:

• obtaining, from a first base station apparatus that belongs to a first communication system that uses a first frequency band, setting information indicating setting of measurement in a second frequency band that is different from the first frequency band and is used for a second communication system;
• performing measurement of a predetermined signal transmitted from a second base station apparatus that belongs to the second communication system, based on the setting information;
• notifying the first base station apparatus of a result of the measurement;
• and
• communicating with the first base station apparatus in accordance with scheduling performed by the first base station apparatus based on the result of the measurement.
