Abstract
Provided is a method in which a terminal conducts an operation for retransmission using a frame divided into downlink subframes and uplink subframes, the method including: receiving a data burst transmitted from a base station; determining a feedback frame offset based on the relationship between a range determined based on division information of the frame and a downlink subframe index in which the data burst has been transmitted; determining indices of a frame and uplink subframe for transmitting a feedback signal based on the frame offset; transmitting the feedback signal to the base station in the determined indices of the frame and uplink subframe; and if an NACK message is included in the feedback signal, receiving the data burst retransmitted from the base station.
