Abstract
A wireless device determines a first transmission power for a first signal and a second transmission power for a second signal. When a calculated power value is more than an allowable transmission power a power control mechanism is employed. The wireless device reduces signal transmission power of a signal during an overlap period if the overlapping in time is less than a first duration. The wireless device reduces signal transmission power of a signal during at least a non-overlap period if the overlapping in time is more than a second duration.
