1. A wireless device comprising:
one or more processors; and
memory storing instructions that, when executed by the one or more processors, cause the wireless device to:
receive a layer 1 or layer 2 triggered mobility (LTM) cell switch command, wherein the LTM cell switch command:
comprises a configuration index indicating a cell for an LTM procedure; and
does not comprise a timing advance command with a timing adjustment value for a primary timing advance group (PTAG) of the cell; and
in response to receiving the LTM cell switch command not comprising the timing advance command with the timing adjustment value for the PTAG, start a time alignment timer associated with the PTAG after measuring a timing advance of the cell.
