A control method executed by a terminal apparatus for connecting to a base station apparatus, comprising:

• determining a need to change capability information notified to the base station apparatus;
• transmitting to the base station apparatus, in response to determining that the capability information needs to be changed, a signal for transmission of the capability information to the base station apparatus in a state where no inquiry about the capability information is received from the base station apparatus while connection with the base station apparatus is maintained;
• and
• notifying the base station apparatus of the changed capability information.
