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 in the first cell group is derived employing a first cell in the first cell group; and
uplink transmission timing in the second cell group is derived employing a second cell in the second cell group;
transmitting a first signal starting in a first subframe of a cell of the first cell group overlapping in time with a configured transmission of a second signal starting in a second subframe of the second cell group; and
dropping transmission of the second signal if a power value is more than an allowable transmission power, wherein a calculation of the power value considers transmission power of the first signal and the second signal if the first subframe and the second subframe overlap in time with more than a first duration.

Abstract
A first signal is transmitted starting in a first subframe of a cell of a first cell group. A second signal is configured for transmission in a second subframe of a second cell group. Transmission of the second signal is dropped if a power value is more than an allowable transmission power. A calculation of the power value considers transmission power of the first signal and the second signal if the first subframe and the second subframe overlap in time with more than a first duration.

11. A wireless device comprising:
-
one or more processors; and memory storing instructions that, when executed, cause the wireless device to; receive, 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 in the first cell group is derived employing a first cell in the first cell group; and uplink transmission timing in the second cell group is derived employing a second cell in the second cell group; transmit a first signal starting in a first subframe of a cell of the first cell group overlapping in time with a configured transmission of a second signal starting in a second subframe of the second cell group; and drop transmission of the second signal if a power value is more than an allowable transmission power, wherein a calculation of the power value considers transmission power of the first signal and the second signal if the first subframe and the second subframe overlap in time with more than a first duration. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
