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.

Abstract: A terminal apparatus for communicating with a base station apparatus includes a receiver configured to receive an RRC reconfiguration message from the base station apparatus, and a processing unit.

Abstract: A first terminal apparatus for performing sidelink communication receives a first message from a second terminal apparatus, determines information based on a Reference Signal Received Power (RSRP) of the first message received from the second terminal apparatus, and transmits a second message including the information to a third terminal apparatus, wherein the first message and the second message are messages used to select a terminal apparatus being responsible to forward a sidelink transmission of the second terminal apparatus to the third terminal apparatus.

Abstract: A terminal apparatus includes a receiver configured to receive a first RRC message and/or a second RRC message from the base station apparatus, and a processing unit. In a case that an MRB of a first type is established with the first RRC message, and all of radio bearers are to be released, the processing unit releases the MRB of the first type. In a case that the MRB of a second type is established with the second RRC message, and all of the radio bearers are to be released, the processing unit does not release the MRB of the second type.

Abstract: A terminal apparatus for communicating with a base station apparatus includes a receiver configured to receive a Radio Resource Control (RRC) reconfiguration message including a first parameter from the base station apparatus, and a processing unit. The processing unit performs first processing on each session not to be added with the first parameter among the sessions already configured for the terminal apparatus, based at least on that a parameter indicating a full configuration is included in the RRC reconfiguration message. The first parameter is an MRB configuration list parameter. The first processing includes indicating to an upper layer that a user plane resource for each session not to be added has been released.
