| 摘要 |
The invention relates to a method for a terminal to perform a hybrid automatic repeat request (HARQ) in a wireless access system that supports cooperative terminal communication, including: allocating a second carrier from a base station through a first carrier, the first carrier being used for data transmission to the base station and the second carrier being used for data transmission to another terminal; receiving a preamble and configuration information on the second carrier from the base station; transmitting data to the other terminal in an uplink subframe of the second carrier on the basis of the received configuration information; and receiving acknowledgement (ACK) or non-acknowledgement (NACK) for the transmitted data from a downlink subframe of the second carrier related to the uplink subframe. The configuration information of the second carrier includes frame structure information used in the second carrier, the frame structure information includes the arrangement and linkage of the uplink subframe and the downlink subframe in a frame, and the uplink subframe and the downlink subframe are allocated to the frame at different times. |
