FIELD: radio engineering, communication.
SUBSTANCE: invention relates to mobile communication. A relay station comprises quality class determining module configured to determine, based on a received signal from a first communication station, a first quality indicator indicating the expected radio communication quality; a display module configured to compare the received signal with a radio link having quality indicated by the second quality indicator, which corresponds to the first quality indicator in a correspondence relationship quality indicators used in communication between the first communication station and the relay station, and quality indicators used in communication between the relay station and the second communication station; and a transmission module configured to transmit the received signal to the second communication station using said radio link.
EFFECT: providing quality of service and matching communication parameters between a user device and a relay station with communication parameters between a relay station and a base station.
