Method and apparatus for controlling uplink power in wireless

Have described a method and apparatus for controlling uplink transmission power are provided. A method for controlling uplink transmission power, but receives a signal on the down-link channel, wherein the signal is a primary cell, the method, comprising information about the transmission power indicating a power control mode (PCell: primary cell) and the secondary cell (SCell: secondary cell) determining whether asynchronous or synchronous, with the P-cell and S cell is based on whether asynchronous or synchronous, with the information about the transmission power, the S cells for determining maximum transmission power, and transmitting the cell signals S on the basis of the maximum transmission power for the S cells.
