1. A method comprising:
- receiving, by a wireless device, at least one control message comprising configuration parameters of a plurality of cells comprising a first cell group and a second cell group, wherein;
uplink transmission timing associated with the first cell group is based on a first cell of the first cell group; and
uplink transmission timing associated with the second cell group is based on a second cell of the second cell group; and
transmitting a first signal in a first subframe of the first cell group and transmitting a second signal via the second cell group, wherein the first signal overlaps, in time, with the second signal in a second subframe, and wherein a signal transmission power of the first signal is scaled if a power value exceeds an allowable transmission power and if a duration of the overlap in time exceeds a duration threshold.

Abstract
A wireless device transmits a first signal in a first cell group and transmits a second signal in a second cell group. The wireless device adjusts a signal transmission power of one of the first signal and the second signal if a power value exceeds an allowable transmission power and if an overlapping in time exceeds a first duration.
