Abstract: A method for changing a coverage enhancement (CE) mode at a user equipment (UE) in a wireless communication system in a wireless communication system is disclosed. The method includes steps of determining a CE mode level to be changed, transmitting a CE mode change request message to a network based on the determined CE mode level, and receiving a CE mode change message from the network via a physical downlink control channel. Especially, when the determined CE mode level is greater than a current CE mode level, a random access preamble associated with the determined CE mode level is transmitted to the network as the CE mode change request message.

Abstract: A method and apparatus for configuring a cell in a wireless communication system is provided. A user equipment (UE) receives a radio resource control (RRC) message which includes a configuration for a secondary cell (SCell) and an indication of an initial state of the SCell. The initial state of the SCell is set to either one of an activated state and deactivated state. The UE configures the SCell based on the configuration and the initial state of the SCell.

Abstract: Suggested is a novel condition for a media access control (MAC) entity in user equipment (UE) reselecting a sidelink resource in a wireless communication system. The MAC entity of the UE can reselect a sidelink resource when a configured sidelink grant does not satisfy a latency requirement according to ProSe per-packet priority (PPPP). More particularly, configuration is performed by an upper layer so that the MAC entity transmits on the basis of sensing using a resource pool; the MAC entity selects generation of a configured sidelink grant corresponding to transmission of a plurality of MAC protocol data units (PDU); and when data is available in a sidelink traffic channel (STCH) and the configured sidelink grant does not satisfy the latency requirement according to the PPPP, a sidelink resource is reselected.

Abstract: A method and apparatus for determining to be a relay UE in a wireless communication system. A user equipment (UE) receives reference signal received power (RSRP) based criteria from a network, and determines to be a relay UE when a specific condition corresponding to the RSRP based criteria is met. The UE may further receive a hysteresis value from the network. When a measured RSRP of the UE plus the hysteresis value is below the RSRP threshold, the UE may determine to be a relay UE.

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.
