Abstract
The present invention relates to a wireless communication system, and more particularly to a method and an apparatus for transmitting uplink signals in a wireless communication system for supporting multiple antenna transmissions. The method for transmitting the uplink signals in the wireless communication system for supporting the multiple antenna transmissions according to an embodiment of the present invention comprises the steps of: receiving a PDCCH (Physical Downlink Control Channel) including uplink grant information for indicating a first rank value; precoding uplink data on the basis of the first rank value; precoding uplink control information on the basis of a second rank value; multiplexing the precoded uplink data and the uplink control information on a PUSCH (Physical Uplink Shared Channel) resource; and transmitting the multiplexed uplink data and the uplink control information. The uplink control information can include channel state information and the second rank value can be less than or equal to the first rank value.
