    • A method of performing a hybrid automatic repeat request (HARQ) of a relay station in a backhaul link of a multi-carrier system is provided. The method includes: receiving backhaul downlink data through at least one carrier between a first carrier and a second carrier; transmitting acknowledgement/not-acknowledgement (ACK/NACK) for the backhaul downlink data through an uplink component carrier; and receiving new backhaul downlink data or retransmitted backhaul downlink data in accordance with the transmitted ACK/NACK through at least one carrier between the first carrier and the second carrier, wherein the first carrier is a component carrier dedicated to the backhaul downlink between a base station and the relay station, and the second carrier is a component carrier used in both the backhaul downlink and an access downlink between the relay station and a relay user equipment at different times.
    • 提供了一种在多载波系统的回程链路中执行中继站的混合自动重传请求(HARQ)的方法。 该方法包括:通过第一载波和第二载波之间的至少一个载波接收回程下行链路数据; 通过上行链路分量载波发送用于回程下行链路数据的确认/不确认(ACK / NACK); 以及通过所述第一载波和所述第二载波之间的至少一个载波,根据所传输的ACK / NACK接收新的回程下行链路数据或重传的回程下行链路数据,其中所述第一载波是专用于基站之间的回程下行链路的分量载波 和中继站,第二载波是在不同时间在回程下行链路和中继站与中继用户设备之间的接入下行链路中使用的分量载波。
