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 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: 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.

Abstract: Provided are a method of receiving a multimedia broadcast multicast service (MBMS) service by a terminal in a wireless communication system, and an apparatus supporting the method. The method may include: receiving from a base station a broadcast identifier (ID) and the total number of physical resource blocks (PRBs) within a system bandwidth; selecting a specific PRB from one or more PRBs within the system bandwidth by using the received broadcast ID and total number of PRBs; and receiving the MBMS service on the selected specific PRB.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method for performing, by a first user equipment (UE) connected with one or more UEs, a handover procedure in a wireless communication system, the method comprising: transmitting, to a serving cell, first information including a channel quality between the first UE and the one or more UEs based on a predetermined configuration; receiving, from the serving cell, second information indicating a second UE to perform a handover procedure with the first UE among the one or more UEs in response to the first information; and performing the handover procedure with the second UE indicated to perform the handover procedure by the second information.

Abstract: In an embodiment, a user equipment (UE) receives common scheduling information which schedules the data across multiple multicast-broadcast single-frequency network (MBSFN) areas, and receives the data according to the common scheduling information. In another embodiment, the UE receives common scheduling information which schedules the data on either a physical multicast channel (PMCH) or a physical downlink shared channel (PDSCH), and receives the data on a corresponding channel according to the common scheduling information. The data may correspond to a vehicle-to-everything (V2X) message.
