  • Patent number: 12041684
    Abstract: A terminal apparatus includes: a receiver that receives an RRC message from a base station apparatus; and a processing unit that performs processing of RRC. The processing unit causes, when first information is in the RRC message, a first timer to start in a running state, and considers, at least when a random access problem indication is received from a MAC entity of the group and the first timer is not running, or when a random access problem indication is received from a MAC entity of the group and the first timer is running under a specific condition, a radio link failure for the group to be detected. When the radio link failure for the group is detected and that the first timer is running under the specific condition, the processing unit suspends transmission of all radio bearers in the group, and resets the MAC entity of the group.
