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. A method for transmitting control information regarding uplink multiple antenna transmission in a base station according to one embodiment of the present invention may comprise the steps of: transmitting DCI for scheduling uplink transmission of a plurality of data blocks through a PDCCH; receiving the plurality of data blocks scheduled by the DCI using a plurality of layers; transmitting, through a PHICH, information which indicates ACK or NACK for each of the plurality of received data blocks; and receiving a retransmission of the negative-acknowledged data blocks using one or more layers. When the number of the negative-acknowledged data blocks is not the same as the number of data blocks indicated in the PDCCH, one or more layers may be the same as those used in a previous transmission of the negative-acknowledged data blocks. |
