Abstract: A method and apparatus for indicating change of a coverage enhancement (CE) mode in a wireless communication system is provided. A CE mode for coverage enhancement may be defined. A user equipment (UE) determines whether the CE mode changes. If it is determined that the CE mode changes, the UE detaches with a network, and re-attaches with the network based on the changed CE mode.

Abstract: The invention relates to a method comprising classifying user equipment (UE) cells, to which carrier aggregation is applied, into a plurality of time advance groups. Uplink-time synchronization is managed using the time synchronization of a primary cell (Pcell) in the time synchronization group to which the primary cell belongs. For other time synchronization groups, the uplink time synchronization is managed using the time synchronization of a secondary cell (SCell) that is particularly set in the relevant time synchronization group. Thus, the plurality of time synchronizations can be effectively managed for the UE and a base station (BS).

Abstract: A method and apparatus for indicating quality of service (QoS) of device-to-device (D2D) data in a wireless communication system is provided. A first user equipment (UE) determines a value of a field in a header based on an identified QoS of the D2D data, and transmits to a second UE a layer 2 protocol data unit (PDU), which includes the header including the field having the determined value. Upon receiving the layer 2 PDU, the second UE identifies the QoS of the D2D data based on the value of the field in the header.

Abstract: A method and a user equipment (UE) are provided for steering traffic within a visitor public land mobile network (VPLMN) in a wireless communication system. The UE transmits to a network, access network discovery and selection function (ANDSF)-related information comprising information on at least one of a home ANDSF (H-ANDSF) configured by a home public land mobile network (HPLMN) or a visitor ANDSF (V-ANDSF) configured by the VPLMN. The UE receives, from the network, traffic steering information which is generated by the network based on the ANDSF-related information, and steers traffic based on the received traffic steering information. The ANDSF-related information indicates whether the H-ANDSF or the V-ANDSF is an enhanced ANDSF. When the ANDSF-related information indicates that the H-ANDSF or the V-ANDSF is the enhanced ANDSF, the traffic steering information comprises a radio access network (RAN) rule parameter corresponding to a RAN rule configured by the network.

Abstract: Provided is a method for reporting multimedia broadcast and multicast service (MBMS) information by a terminal in a wireless communication system. The method comprises: determining whether or not to permit the logging of MBMS information; logging the MBMS information if the logging of the MBMS information is permitted; and reporting the logged MBMS information to a network. Whether or not to permit the logging of the MBMS information is determined on the basis of logging scope.

Abstract: Provided is a method for communicating performed by a terminal in a wireless communication system. The method comprises receiving a traffic routing configuration from a first access network, the traffic routing configuration specifying a traffic routing criteria for routing and processing traffic, discovering at least one second network entity by searching a second access network, conducting a traffic routing evaluation to determine whether the at least one second access network satisfies the traffic routing criteria, reporting a routing evaluation result to the first access network when the traffic routing criteria are satisfied, receiving a traffic routing indication from the first access network, and processing the traffic based on the traffic routing indication. When the traffic routing indication indicates traffic of the first access network is processed through the second access network, the traffic of the first access network is processed through the second access network.

Abstract: A method for changing a coverage enhancement mode in a wireless communication system supporting a coverage enhancement (CE) is disclosed. For this, the method comprising: receiving, from a network, information on a CE mode level supported by the network, wherein the information on the supported CE mode level indicates a highest level among CE mode levels currently supported by the network; determining a CE mode level of the UE; and transmitting, to the network, a first message for requesting a change of the supported CE mode level, when the determined CE mode level of the UE is higher than or equal to the supported CE mode level.

Abstract: A disclosure of the present specification provides a network access blocking method performed by a user equipment. The method may comprise the steps of: receiving application specific congestion control for data communication (ACDC) blocking information and access class barring (ACB) blocking information; determining the category of an application being executed according to a network access attempt by the application; performing an ACDC blocking check on the basis of the determined category and the received ACDC blocking information. Here, when the network access attempt by the application is not blocked as a result of the ACDC blocking check, an ACB blocking check on the basis of the ACB blocking information may be skipped.
