    摘要: The present invention relates to a wireless access system, and more particularly, to a method for controlling uplink transmission power in consideration of a transmission rank in a multi-antenna environment. A method for controlling the transmission power of an uplink data channel at a transmitting end which supports a plurality of transmission ranks according to one embodiment of the present invention, comprises the steps of: determining a first transmission power using at least one rank variable dependent on the transmission rank in a specific subframe; comparing the determined first transmission power with a second transmission power which is the preset maximum transmission power; and determining the value judged to be smaller than the result of the comparison to be the transmission power of the data channel.
