Abstract:
Disclosed is a method for transmitting control information on uplink multi-antenna transmission from a base station and the method includes: transmitting DCI that schedules uplink transmission of a first data block and a second data block through a PDCCH; receiving the first and second data blocks scheduled by the DCI; transmitting information indicating ACK or NACK for the received first and second data blocks, respectively, by using a first PHICH for the first data block and a second PHICH resource for the second data block; receiving a retransmission for a negative-acknowledged data block; and transmitting information indicating ACK or NACK of the retransmission of the negative-acknowledged data block by using the first PHICH resource when the number of negative-acknowledged data blocks is not identical to the number of data blocks that the PDCCH indicates.
