Abstract
A wireless device transmits a random access preamble (RAP) on a first cell of a first cell group. If a configured transmission of an uplink transport block (UTB) or an uplink control information (UCI) on a second cell of a second cell group overlaps in time with transmission of the RAP, the wireless device adjusts transmission power of at least one of the UTB or the UCI. If a configured transmission of a sounding reference signal (SRS) on a third cell overlaps in time with transmission of the preamble, the wireless device drops the configured SRS transmission if a calculated total transmission power exceeds a first value.
