AI Technical Summary
Technical Problem
Current Layer 1 measurements in cellular mobile communication systems are limited to periodic, aperiodic, and semi-persistent events, lacking support for event-triggered reporting, which hinders efficient communication control.
Method used
A terminal device and base station device are designed to perform beam measurements based on specific conditions, with the terminal device transmitting measurement results via MAC CE to the base station, and the base station transmitting RRC signaling to manage these measurements, enabling efficient communication control.
Benefits of technology
This approach allows for efficient communication control by supporting event-triggered reporting, enhancing the flexibility and responsiveness of communication systems.

Abstract
Provided is a terminal device that communicates with a base station device, the terminal device comprising a reception unit, a processing unit, and a transmission unit. The reception unit receives, from the base station device, a setting related to one or a plurality of measurements. The processing unit measures a measurement item of a certain beam once or a plurality of times on the basis of the setting, and on the basis of a determination that the measurement item satisfies one condition, includes, in a MAC CE, the one or a plurality of beam measurement results and an information element for indicating whether the beam satisfies the condition. The transmission unit transmits the MAC CE to the base station device.
