EFFECTIVE METHOD AND DEVICE FOR TRANSMITTING CONTROL INFORMATION FOR SUPPORTING UPLINK MULTI-ANTENNA TRANSMISSION

摘要

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 ACK or NACK with respect to a first and a second received 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 ACK or NACK for the retransmission of the negative-acknowledged data block by using the first PHICH resource reardless of which PHICH resource was used to transmit the ACK or NACK for the retransmitted data block.
