Abstract: A wireless device receives one or more radio resource control (RRC) messages comprising configuration parameters of uplink switching for a plurality of bands. The plurality of bands comprise a first band associated with a first priority, and a second band associated with a second priority. The wireless device determines, for an uplink switching between the first band and the second band, an uplink switching period location to be in the first band, based on the first priority being lower than the second priority. The wireless device transmits, based on the uplink switching period location, an uplink transmission via one of the first band and the second band.
