Title:
TERMINAL DEVICE, BASE STATION DEVICE, AND METHOD
Document Type and Number:
WIPO Patent Application WO/2023/063345
Kind Code:
A1
Abstract:
A processing unit of this terminal device communicates with a base station device using an MCG and an SCG and determines whether or not signaling that is transmitted from the base station device and that notifies that the SCG is to be configured in an inactive state includes information indicating that wireless link monitoring will be performed, and then stops a timer (T310) of a PSCell of the inactivated SCG in the terminal device if it is determined that the signaling does not include the information indicating that wireless link monitoring will be performed in the inactive state of the SCG. The timer (T310) starts when an out-of-sync notified from a PHY entity of the terminal device is successively received in the PSCell a prescribed number of times (N310 times), and stops when an in-sync is successively received in the PSCell a prescribed number of times (N311 times) from the PHY entity of the terminal device. The processing unit executes an SCG failure information procedure when the timer (T310) expires.
