RADIO COMMUNICATION SYSTEM, BASE STATION DEVICE, TERMINAL DEVICE, RADIO COMMUNICATION METHOD, AND INTEGRATED CIRCUIT

摘要

There is provided a radio communication system in which a first base station device and a second base station device communicate with a terminal device. The terminal device transmits report information corresponding to data transmission of each of the base station devices, to the first base station device and the second base station device. The terminal device transmits report information corresponding to data transmission of the second base station device to the first base station device in a case where occurrence of a problem is detected in a radio link between the second base station device and the terminal device. The first base station device detects occurrence of a problem in the radio link between the second base station device and the terminal device in a case where the report information corresponding to the second base station device is received from the terminal device.
