Abstract: A method and apparatus for transmitting a message in a wireless communication system is provided. A user equipment (UE) submits a message to a packet data convergence protocol (PDCP) layer and a radio link control (RLC) layer, detects a radio link failure or a handover failure, checks whether the RLC layer receives acknowledgement (ACK) to the message from the network, reestablishes the connection with the network, and retransmits the message upon the reestablishment if the RLC layer does not receive the ACK to the message.

Abstract: Provided are a method by which a terminal processes an emergency call in a wireless communication system, and an apparatus for supporting the same. The method comprises: selecting a cell when a radio link failure (RLF) is generated; transmitting a RRC connection re-establishment request message to the selected cell; stopping an expired timer if a suitable cell or a cell using different radio access technology (RAT) is not selected within a certain time when the RLF is generated in the emergency call process of the terminal and the selected cell is an acceptable cell; and transmitting the RRC connection reestablishment request message.

Abstract: A method and apparatus for transmitting uplink control signals in a wireless communication system is provided. A user equipment (UE) transmits a first uplink control signal for a first type cell to a first eNodeB (eNB) on a first physical uplink control channel (PUCCH) in the first type cell. The UE transmits a second uplink control signal for a second type cell to a second eNB on a second PUCCH in the second type cell. The UE transmits a third uplink control signal for a third type cell to the second eNB on the second PUCCH in the second type cell. The third type cell is a cell where a PUCCH is not configured, and the UE supports dual connectivity with the first eNB and the second eNB.

Abstract: A method and apparatus for handling a secondary cell (SCell) deactivation timer in a wireless communication system is provided. When a user equipment (UE) is receiving a specific channel or service on a SCell from a network, the UE may start or restart a SCell deactivation timer whenever the SCell deactivation timer expires. Alternatively, the UE may delay expiry of a SCell deactivation timer whenever the SCell deactivation timer expires.
