1. A wireless device comprising:
- one or more processors; and
memory storing instructions that, when executed, cause the wireless device to;
receive at least one message comprising configuration parameters of a plurality of cells being 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 on a cell of the first cell group; and
if a configured transmission of sounding reference signals (SRSs) overlaps in time with transmission of the first signal and if a calculated total transmission power exceeds a first power value;
drop a first subset of the SRSs; and
transmit a second subset of the SRSs.

Abstract
A wireless device receives message(s) configuring cell groups and transmissions of sounding reference signals (SRSs). Uplink transmission timing in a first cell group is derived employing a cell in the first cell group and uplink transmission timing in a second cell group is derived employing a second cell in the second cell group. A first signal is transmitted on a cell of the first cell group. A first subset of the SRSs are dropped and a second subset of the SRSs are transmitted if transmission of SRSs overlap in time with transmission of the first signal and a calculated total transmission power exceeds a first power value.
