RELAY STATION AND RELAY METHOD FOR RELAYING COMMUNICATIONS BETWEEN USER EQUIPMENT AND BASE STATIONS.

摘要

A relay station that relays wireless communications from a first communication station to a second communication station comprises: a quality class identification unit that identifies a first quality indicator indicating the quality expected for the wireless communications using the signals received from the first communication station; a mapping unit that maps the received signals to radio bearers having the quality indicated by a second quality indicator that corresponds to the first quality indicator in the corresponding relationships between a quality indicator for communications between the first communication station and relay station and a quality indicator for communications between the relay station and the second communication station; and a transmitting unit that transmits the received signals to the second communication station using a radio bearer.
