METHOD AND APPARATUS FOR EFFICIENTLY TRANSMITTING CONTROL INFORMATION TO SUPPORT UPLINK MULTIPLE ANTENNA TRANSMISSION |
摘要 |
The present invention relates to a wireless communication system, and to a method and apparatus for efficiently transmitting control information to support an uplink multiple antenna transmission technique. According to one embodiment of the present invention, a method for transmitting control information regarding uplink multiple antenna transmission may comprise the steps of: transmitting DCI for scheduling the uplink transmission of a plurality of data blocks through a PDCCH; receiving the plurality of data blocks scheduled by the DCI; transmitting information which indicates positive acknowledgement or negative acknowledgement to each of the plurality of received data blocks through the PHICH; and receiving retransmission for the negative acknowledged data blocks. When the number of the negative-acknowledged data blocks is not equal to the number data blocks indicated in the PDCCH, a pre-coding matrix, which is for the number of transmission layers equivalent to that of layers corresponding to the negative-acknowledged data blocks, may be used for retransmission. |
