Claim Text:
1. A method for performing uplink MIMO transmission, the method comprising: transmitting a first data block and a second data block at a first subframe 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 disabling of the second data block; setting a HARQ feedback information state on the second data block to an ACK state; and performing retransmission of the first data block at a third subframe on the basis of the uplink scheduling control information on the first data block, wherein retransmission of the second data block is not performed until uplink scheduling control information on the second data block is received, and wherein the HARQ feedback information state on the second data block is set to the ACK state regardless whether any HARQ feedback information is indicated or HARQ feedback information indicates NACK state or ACK state.
