    摘要: A method of performing hybrid automatic repeat request (HARQ) by a source station in a wireless communication system is provided. The method includes: transmitting data to a destination station at a transmission start time; receiving an acknowledgment (ACK) or negative-acknowledgement (NACK) signal for the data from the destination station after a first transmission time interval elapses from the transmission start time; and upon receiving the NACK signal, retransmitting the data after a second transmission time interval elapses from the transmission start time, wherein the second transmission time interval is one transmission time interval selected from a plurality of predetermined transmission time intervals. Accordingly, the wireless communication system can perform a heterogeneous HARQ process in which an HARQ period, an ACK/NACK transmission start time, and the like are different.

    摘要: A method of allocating a radio resource for a relay station in a wireless communication system is disclosed. The method comprise allocating a relay zone to the relay station in a subframe and transmitting a relay control channel to the relay station by using the relay zone, wherein the subframe comprises a plurality of orthogonal frequency division multiplexing (OFDM) symbols in a time domain and a plurality of subcarriers in a frequency domain, wherein the subframe is divided into a user zone used by a user equipment in a cell and the relay zone used by the relay station, and wherein the relay zone comprises some of the plurality of subcarriers. According to the present invention, a subframe structure provides backward compatibility with a legacy wireless communication system. A relay station can effectively find a radio resource allocated to the relay station, thereby decreasing a decoding time.

This invention provides a sub-frame structure which is compatible with existing wireless communication systems. This method allows the continued use of existing control channel systems or base signal structures. The method is also capable of supporting advanced features.
