Abstract:
1. In a communication system wherein a User Equipment (UE) transmits at least two data channels in at least two respective component carriers such that a first data channel of the at least two data channels conveys control information and data, a method for controlling the transmission power of each data channel, the method comprising: reducing a transmission power allocated to at least one of the at least two data channels relative to a respective nominal transmission power when a total nominal transmission power for the at least two data channels exceeds a predetermined value; and transmitting the at least two data channels, wherein the first data channel of the at least two data channels is transmitted with a nominal transmission power of the first data channel, and second data channels of the at least two data channels are transmitted with a total power that is less than or equal to a value obtained by subtracting the nominal transmission power of the first data channel of the at least two data channels from the predetermined value, and wherein the at least two data channels are Physical Uplink Shared Channels.
