Method and system for subframe scheduling of network-to-relay link in relay enhanced cellular system

Relay the transmission period information of the service to the base station, and the base station by changing the period of a sub-frame position information based on the sub-frame scheduled to avoid the degradation due to the execution of the retransmission method is not disclosed. Sub-frame scheduling method includes transmitting to the base station is set to the subframe information; The method comprising the relay is executed to set up the service on the basis of the sub-frame information; Wherein the relay transmits the period information of the service to the base station; Step of changing the sub-frame information on the basis of the period information is the base station; And transmitting the sub-frame information, the base station is changed to the relay. Sub-frame, a relay, a base station, period information, the retransmission.
