    摘要: The present description relates to a wireless communication system, and more particularly, to a method and apparatus for uplink multiple input multiple output (MIMO) transmission. A method for performing an uplink MIMO transmission according to one embodiment of the present invention comprises the following steps: transmitting, from a first subframe, a first data block and a second data block through a first HARQ process and a second HARQ process, respectively; receiving, at a second subframe, uplink scheduling control information on the first data block and control information which indicates inactivation of the second data block; setting HARQ feedback information on the second data block to an ACK state; and performing retransmission of the first data block from a third subframe on the basis of the uplink scheduling control information on the first data block. Retransmission of the second data block may not be performed until uplink scheduling control information on the second data block is received.

    摘要: 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.
