Patent ID: 8688165

Claim:
A method of transmit power control implemented by a mobile terminal, the method comprising: receiving separate transmit power control commands for, respectively, one or more first communication channels transmitted in a first frequency region and one or more second communication channels transmitted in a second frequency region; computing a power offset indicative of the difference between the commanded power of one or more of the first communication channels and the commanded power of one or more of the second communication channels; and selectively performing transmit power control of said first and second communication channels on either an independent basis, according to the respective transmit power control commands received, or a joint basis, by performing transmit power control on a joint basis if both the computed power offset falls below a pre-determined threshold value and the total power commanded across all, or substantially all, of the first and second communication channels exceeds a pre-determined total power threshold value, and otherwise performing transmit power control on an independent basis.
