A wireless device transmits channel state information (CSI) fields of a secondary cell on a first cell. The wireless device receives, in subframe n, a message comprising one or more configuration parameters indicating that CSI transmission resources for the secondary cell is on a second cell different from the first cell. The wireless device stops, in subframe n+p, transmission of CSI fields of the secondary cell on the first cell. The wireless device starts, in subframe n+k, transmission of CSI fields of the secondary cell on the second cell, wherein k is a number greater than p.
