EFFICIENT CONTROL INFORMATION TRANSMISSION METHOD AND DEVICE FOR ASSISTING UPLINK MULTIPLEX ANTENNA TRANSMISSION

摘要

PROBLEM TO BE SOLVED: To provide efficient control information transmission method and device for assisting an uplink multiplex antenna transmission technique.SOLUTION: A method for transmitting control information relating to uplink multiplex antenna transmission in a base station according to one embodiment of the present invention includes: transmitting a DCI for scheduling first data block and second data block uplink transmission through a PDCCH; receiving the first data block and second data block scheduled by the DCI; transmitting information indicating ACK or NACK for each of the received first data block and second data block by using a first PHICH resource for the first data block and using a second PHICH resource for the second data block; and receiving a retransmission for the data block for which NACK was returned.
