1. A base station device in a communication system including a terminal device, the base station device, and a relay device that relays communication between the terminal device and the base station device, the base station device comprising:
a processor configured to perform, when the terminal device performs wireless communication by using both a first wireless communication method that is a wireless communication method with the base station device and a second wireless communication method that is a wireless communication method with the relay device, data communication by converging the wireless communication in a convergence layer in the first wireless communication method; and
a communicator configured to:
identify, when the relay device relays, by the first wireless communication method between the relay device and the base station device, first data that is transmitted and/or received by the second wireless communication method between the terminal device and the relay device, a bearer in the first wireless communication method to which the first data belongs,
identify, when the relay device relays, by the second wireless communication method between the relay device and the base station device, second data that is transmitted and/or received by the second wireless communication method between the terminal device and the relay device, a bearer in the first wireless communication method to which the second data belongs, and
transmit and/or receive the first and second data.
