Abstract

A terminal device includes a wireless communication part configured to wirelessly communicate with base station devices; a link controller configured to establish a link with a primary base station device (PCell) so as to enable a wireless communication via the wireless communication part while establishing a link with a secondary base station device (SCell) so as to enable a wireless communication via the wireless communication part; a primary base station link failure detector configured to detect a radio link failure in the wireless communication with the primary base station device based on the predetermined condition; and a primary base station link failure information transmitter configured to wirelessly transmit the information, concerning the radio link failure with the primary base station device, to the secondary base station device when the primary base station link failure detector detects the radio link failure status.
