Uplink Power Control For Multiple Component Carriers
First Claim
1. A method, comprising:
- determining if a sum of transmit powers of individual component carriers of a plurality of component carriers is less than a maximum user equipment transmit power;
adjusting, if needed, the transmit power of one or more of the plurality of component carriers if the sum of the transmit powers of the individual component carriers is not less than the maximum user equipment transmit power; and
transmitting the component carriers to a network access node.

Abstract
A first method includes determining if a sum of the transmit powers of individual component carriers is less than a maximum user equipment transmit power, adjusting the transmit power of one or more of the component carriers if the sum of the transmit powers of the individual component carriers is not less than the maximum user equipment transmit power, and transmitting the component carriers to a network access node. A second method includes identifying a component carrier with minimum transmit power and a component carrier with a maximum transmit power, calculating a power difference, determining if the power difference is greater than a predetermined maximum power difference and, if it is, increasing the transmit power of the component carrier with minimum transmit power by a first amount and decreasing the transmit power of the component carrier with the maximum transmit power by a second amount.

9. A method, comprising:
-
identifying a component carrier with a minimum transmit power and a component carrier with a maximum transmit power; calculating a power difference as a difference between the maximum transmit power and the minimum transmit power; determining if the power difference is greater than a predetermined maximum power difference and, if it is, increasing the transmit power of the component carrier with minimum transmit power by a first predetermined amount and decreasing the transmit power of the component carrier with the maximum transmit power by a second predetermined amount; and if there are more than two component carriers, repeating the identifying, calculating and determining until the power difference is less than the predetermined maximum power difference such that the maximum power difference between component carriers is constrained to be less than or equal to the predetermined maximum power difference. - View Dependent Claims (10, 11, 12, 13, 14)

16. An apparatus comprising:
-
at least one processor; and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following; determining if a sum of transmit powers of individual component carriers of a plurality of component carriers is less than a maximum user equipment transmit power; adjusting, if needed, the transmit power of one or more of the plurality of component carriers if the sum of the transmit powers of the individual component carriers is not less than the maximum user equipment transmit power; and transmitting the component carriers to a network access node. - View Dependent Claims (18, 19, 21, 22, 23)
