METHOD AND APPARATUS FOR THE EFFICIENT TRANSMISSION OF CONTROL INFORMATION FOR SUPPORTING UPLINK TRANSMISSION USING MULTIPLE ANTENNAS |
摘要 |
Abstract: The present invention relates to a wireless communication system, and particularly, to an effective method and device for transmitting control information for supporting an uplink multi-antenna transmitting technique. According to one embodiment of the present invention, a method for transmitting control information on uplink multi-antenna transmission from a base station (BS) includes the steps of: transmitting DCI that schedules ulink transmission of a first data block and a second data block through 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 instructing ACK or NACK with respect to the received first and second data blocks, respectively, by using a first PHICH resource with regard to the first data block and a second PHICH resource with regard to the second data block; receiving a retransmission with regard to a negative-acknowledged data block; and transmitting information instructing 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 instructs. |
