Methods and apparatuses are described for wireless communications. Cells may be grouped into a plurality of cell groups. If an uplink transport block (UTB) or an uplink control information (UCI) is configured for transmission via a second cell of a second cell group in parallel with a transmission of a first random access preamble (RAP) via a first cell of a first cell group, a wireless device may adjust transmission power of at least one of the UTB or the UCI. Additionally or alternatively, if a sounding reference signal (SRS) is configured for transmission via a third cell in parallel with transmission of a second RAP, the wireless device may drop the SRS.
