Abstract: A processing unit of a terminal apparatus communicates with a base station apparatus using an MCG and an SCG, determines whether to perform beam failure detection in the terminal apparatus based on whether information indicating whether to perform beam failure detection is included in an SCG deactivation command transmitted from the previous base station apparatus, and the terminal apparatus determines whether to perform beam failure detection based on a determination of whether to perform beam failure detection.

Abstract: A processing unit of a terminal apparatus communicates with a base station apparatus using an MCG and an SCG, and determines whether signalling transmitted from the base station apparatus and notifying that the SCG is to be in a deactivated state includes information indicating that radio link monitoring is to be performed. In a case of determining that the signalling includes no information indicating that the radio link monitoring is to be performed in the deactivated state of the SCG, the processing unit stops a timer (T310) for the PSCell of the deactivated SCG for the terminal apparatus. The timer (T310) is started in a case that a predetermined number (N310) of consecutive out-of-sync indications notified from a PHY entity of the terminal apparatus are received in the PSCell and is stopped in a case that a predetermined number (N311) of in-sync indications are received from the PHY entity of the terminal apparatus in the PSCell.

Abstract: A terminal apparatus for communicating with a base station apparatus using an MCG and an SCG determines (a) whether uplink data has been generated that is to be transmitted on a DRB associated with an RLC entity of the SCG and (b) whether the SCG is deactivated, and in a case of determining that uplink data has been generated that is to be transmitted on the DRB associated with the RLC entity of the SCG and that the SCG is deactivated, the terminal apparatus notifies the base station apparatus via SRB1 that uplink data has been generated that is to be transmitted on the DRB associated with the RLC entity of the SCG.

Abstract: A terminal apparatus determines whether information (first information) indicating whether a state of a secondary cell group is to be changed based on scg-State is included in the RRC signaling, in a case that the first information is not included in the RRC signaling, the state of the secondary cell group is changed based on whether the scg-State is included in the RRC signaling, and in a case that the first information is included in the RRC signaling, the state of the secondary cell group is not changed based on whether the scg-State is included in the RRC signaling.

Abstract: A terminal apparatus for communicating with a base station apparatus includes a receiver configured to receive, from the base station apparatus, a Radio Resource Control (RRC) message indicating handover from NR to a second Radio Access Technology (RAT), and a processing unit configured to perform the handover in accordance with the RRC message. The processing unit releases a Packet Data Convergence Protocol (PDCP) entity and a Service Data Adaptation Protocol (SDAP) entity related to a radio bearer for a Multicast Broadcast Service (MBS) configured for the terminal apparatus, based at least on that the handover has completed, and in a case that the handover fails, the processing unit does not release the PDCP entity and the SDAP entity related to the radio bearer for the MBS configured for the terminal apparatus.

Abstract: A terminal apparatus for communicating with a base station apparatus includes a receiver configured to receive a Radio Resource Control (RRC) release message from the base station apparatus, and a processing unit. The processing unit establishes a radio bearer for a Multicast Broadcast service (MBS) for delivery mode 1. The processing unit determines whether or not a suspend configuration parameter is included in the RRC release message, and in a case that the processing unit determines that the suspend configuration parameter is included, the processing unit suspends the radio bearer for the MBS for the delivery mode 1, and in a case that the processing unit determines that the suspend configuration parameter is not included, the processing unit does not suspend the radio bearer for the MBS for the delivery mode 1. The suspend configuration parameter is a parameter indicating a configuration for an RRC_INACTIVE state.
