Abstract
Provided is a method applied to a terminal apparatus for communicating with a base station apparatus. The method includes the steps of: receiving a first RRC message including a parameter related to a first cell group from the base station apparatus; and transmitting a random access preamble in an SpCell of the first cell group, based on reception of the first RRC message. The random access preamble is transmitted in the SpCell, based on first information being included in the first RRC message and a time alignment timer, in a primary TA group of the first cell group, which is not running.

1-3. (canceled)
A terminal apparatus comprising:
- processing circuitry configured to communicate by using a Master Cell Group (MCG), and a Secondary Cell Group (SCG);
- and
- a receiver configured to receive a Radio Resource Control (RRC) message, wherein
- the processing circuitry is configured to initiate a random access procedure in a Special Cell (SpCell) in the SCG at least based on no inclusion of information indicating bringing of the SCG into deactivated state in the RRC message and no running of a time alignment timer of a primary Time Alignment (TA) group of the SCG.
