METHOD OF RETRANSMISSION FOR SUPPORTING MIMO IN SYNCHRONOUS HARQ

摘要

PURPOSE: A method of retransmission for supporting MIMO in synchronous HARQ is provided to perform efficiently HARQ operation by considering a transmission link of the upper link. CONSTITUTION: A plurality of data unit blocks are transmitted to a receiving terminal. A control channel signal, including the first feedback information indicating the success state of the transmission, is received from the receiving terminal. At least one of data blocks according to a predetermined order is re-transmitted at each transmission time when a transmission link and feedback information indicating a transmission fail.
