Claim of US Patent No. 10,368,322

1. A method comprising:receiving, by a wireless device, at least one control message comprising configuration parameters of a plurality of cells grouped into a plurality of cell groups 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;
determining a transmission power of a transmission comprising a first signal in a first subframe of the first cell group and a second signal in a second subframe of the second cell group, wherein a time overlap is associated with the first signal in the first subframe and the second signal in the second subframe;
responsive to the time overlap satisfying a duration threshold and the transmission power exceeding a power threshold, dropping or adjusting a power of one of the first signal or the second signal; and
transmitting at least one of the first signal via the first cell group or the second signal via the second cell group.
