Patent attributes
Methods and apparatuses are described for wireless communications. Cells may be grouped into a plurality of cell groups. A wireless device may be configured to transmit a first signal via a first cell group that may overlap in time with a second signal via a second cell group. The wireless device may adjust a signal transmission power of at least one of the first signal and the second signal. Additionally or alternatively, the wireless device may drop at least one of the first signal and the second signal. Adjusting and/or dropping at least one of the first signal and the second signal may be based on the overlap in time of these signals satisfying a duration threshold and a total power to transmit the first signal and the second signal exceeding a power threshold.
