Abstract
A wireless device receives a message indicating transmission of a sounding reference signal in a symbol on subframe n on a first cell in a first cell group. The symbol overlaps in time with transmission of a packet on at least one of: subframe n and n+1 in a second cell in a second cell group. The wireless device transmits the sounding reference signal if a power parameter is less than a maximum allowable transmission power in the symbol. A calculation of the power parameter considers transmission power of the packet according to a pre-configured rule.
