Abrégé
(EN)

Systems, apparatuses, and methods are described for wireless communications. A wireless device may transmit a buffer status report. Based on the buffer status report, the wireless device may receive a control command to use radio resources of a secondary cell. The wireless device may transmit a random access preamble via the secondary cell.
