Abstract:
A method for retransmitting data in synchronous Hybrid Automatic Repeat reQuest (HARQ) to support Multiple Input Multiple Output (MIMO) is disclosed. The method includes transmitting a plurality of unit data blocks to a receiver, receiving from the receiver a control channel signal including first feedback information indicating whether the transmission of the plurality of unit data blocks is successful, and retransmitting at least one of the plurality of unit data blocks according to a predetermined order, each unit data block in one Transmission Time Interval (TTI), if a rank is 1 and the first feedback information indicates that the transmission of the plurality of unit data blocks is failed.
