Abstract: A wireless device determines a calculated power for a plurality of signals comprising: a first sounding reference signal (SRS) configured for transmission in a subframe of a licensed assisted access (LAA) cell type and a second SRS configured for transmission in the subframe of a licensed cell type. The wireless device drops or scales at least one of the first SRS or the second SRS based on a transmit power priority. The transmit power priority considers whether the first SRS or the second SRS is configured for transmission on the licensed cell type or the unlicensed cell type.
