Relay station for relaying communication between user apparatus and base station, and relay method

摘要

A relay station includes a signal generation unit configured to generate a signal in the relay station and a receiving unit configured to receive a signal from a first communication station. The relay station further includes a signal generating node identifying unit configured to identify whether a signal to be transmitted to a second communication station is a received signal received from the first communication station or a generated signal generated by the signal generation unit. The relay station further includes a signal transmission unit configured to transmit both or one of the received signal and the generated signal associated with a radio bearer to the second communication station.

1. A relay station for relaying radio communication from a first communication station to a second communication station, comprising:
a packet generation unit configured to generate a signal in the relay station; a receiving unit configured to receive a signal from the first communication station; a signal generating node identifying unit configured to identify whether a signal to be transmitted to the second communication station is a received signal received from the first communication station or a generated signal generated by the packet generation unit; quality indicator conversion unit configured to associate the received signal with a radio bearer having a quality indicated by a second quality indicator corresponding to a first quality indicator determined from the received signal by referring to a predetermined correspondence relationship between first quality indicators in communication between the first communication station and the relay station, and second quality indicators in communication between the relay station and the second communication station, in a case when the signal to be transmitted to the second communication station is the received signal received from the first communication station; a quality indicator setting unit configured to associate the generated signal with a radio bearer having a quality expected for radio communication of the generated signal, in a case when the signal to be transmitted to the second communication station is the generated signal generated by the packet generation unit; and a signal transmission unit configured to transmit both or one of the received signal and the generated signal associated with the radio bearer to the second communication station.
