Abstract: A method performed by a wireless device in a wireless communication system includes receiving multiple thresholds from a base station (BS); measuring a quality of a cell; determining a coverage enhancement (CE) level of the wireless device based on the multiple thresholds and the measured quality of the cell; receiving random access channel (RACH) information including at least one window size value and at least one timer value for contention resolution, from the BS; selecting a window size value and a timer value among the RACH information based on the determined CE level; transmitting a first message for the RACH to the BS; receiving a second message for the RACH based on the selected window size value, from the BS; and starting a timer for contention resolution based on the selected timer value regarding a third message for the RACH. Further, the CE level is determined as a CE level 0, when the measured quality is above or equal to all of the multiple thresholds.

Abstract: The present invention relates to a method for receiving packets by a user equipment (UE) in a wireless communication system. In particular, the method includes receiving a handover command including security information; establishing a connection with a second network; based on detecting a connection failure with the second network, deriving a security key for a first network based on the security information; performing a PDCP re-establishment for one or more radio bearers of the first network based on the security key for the first network; and reporting, to the first network, the connection failure with the second network.

Abstract: While a user equipment (UE) performs a periodic transmission on a first link or a first carrier by using a semi-persistent scheduling (SPS) resource for the first link or the first carrier to an eNodeB (eNB), the UE may receive a SPS resource for a second link or a second carrier from the eNB. Or, a certain event may occur. Then, the UE stops using the SPS resource for the first link or the first carrier, and performs a periodic transmission on the second link or the second carrier by using the SPS resource for the second link or the second carrier to the eNB.

Abstract: Provided is a method for operating a transmission buffer in a wireless communication system. The method is performed by a user equipment (UE), and comprises detecting, in a switching layer, whether a transmission of data on a first transmission link is successful via the lower layer, determining whether to keep the transmission of the data on the first transmission link or to perform the transmission of the data on a second transmission link when the transmission of the data is not successful and performing the transmission of the data on the determined transmission link.

Abstract: A method and apparatus for performing application specific congestion control for data communication (ACDC) in a wireless communication system is provided. A radio resource control (RRC) layer of a user equipment (UE) receives ACDC barring information for a plurality of ACDC categories via system information from a network, determines whether the ACDC barring information for the plurality of ACDC categories contains ACDC barring information for a specific ACDC category selected by upper layers, and if it is determined that the ACDC barring information for the plurality of ACDC categories does not contain ACDC barring information for a specific ACDC category selected by upper layers, performs ACDC barring check by using ACDC barring information for last ACDC category among the plurality of ACDC categories.

Abstract: A method and apparatus for configuring measurements in a wireless communication system is provided. A user equipment (UE) receives a reference signal (RS) indicator from a network, and evaluates whether a measurement report triggering event is satisfied by only using a measurement result based on a RS indicated by the RS indicator. The RS indicator may indicate which RS is used for reporting the measurement result. The RS indicator may indicate a cell-specific reference signal (CRS) or a discovery reference signal (DRS).
