AI Technical Summary

Technical Problem

Existing communication systems face challenges in efficiently utilizing a particular frequency band as an auxiliary for uplink communication while minimizing interference with other systems, such as radio transmission relay devices and public business radio stations.

Method used

The system employs a terminal device and a base station device that communicate across different frequency bands. The terminal device connects to both a primary base station in the first frequency band and a secondary base station in a second frequency band, using the reception quality of a predetermined signal to adjust transmission power and ensure efficient communication.

Benefits of technology

This approach enables efficient communication by allowing the terminal device to adjust its transmission power based on the reception quality in the secondary frequency band, thereby optimizing uplink communication without causing significant interference with other systems.

Abstract

To achieve efficient communication in an environment in which a specific frequency band is used auxiliary for uplink communication.SOLUTION: A terminal device is connected to a first base station device in a first frequency band, is connected to a base station device different from the first base station device in a second frequency band different from the first frequency band, transmits a predetermined signal in the second frequency band, receives information from the first base station device that enables identification of a transmission power when transmitting a signal to a second base station device based on a reception quality of the predetermined signal at the second base station device that operates in the second frequency band and is not treated as being in the same location as the first base station device, identifies the transmission power on the basis of the information, and performs control to transmit a signal to the second base station device in the second frequency band using the identified transmission power.SELECTED DRAWING: Figure 1
