Abstract:
A base station transmits to a wireless device at least one timing-advance command (TAC) for a secondary cell group. Each of the at least one TAC includes a timing-advance value (TAV) to be employed by the wireless device to update a first TAV. The base station transmits, to the wireless device and after the TAT expires, a second TAC with a TAV of zero for the secondary cell group. The base station receives uplink signals from the wireless device according to the updated first TAV.
