Abstract: Provided is a method and an apparatus for transmitting user equipment (UE) assistance information for a semi-persistent scheduling (SPS) to a target evolved NodeB (eNB) in a wireless communication system. A source eNB in a handover, receives the UE assistance information for the SPS from a UE, and transmits the UE assistance information for the SPS to the target eNB. The UE assistance information for the SPS may include a SPS period and a time offset.

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 user equipment (UE) receives, from a network, a semi-persistent scheduling (SPS) configuration and a physical uplink control channel (PUCCH) resource configuration. The PUCCH resource configuration may be included in the SPS configuration. When a change of an SPS operation is required, the user equipment transmits an SPS change request to the network and receives, from the network, an SPS resource grant activated according to the SPS change request. The user equipment changes allocation of a PUCCH resource allocated according to the PUCCH resource configuration, on the basis of the received SPS resource grant. For example, a timing at which or a period in which the PUCCH resource is allocated can be changed.

Abstract: Provided are a method for supporting multimedia broadcast multicast service (MBMS) service continuity by a terminal in a wireless communication system and an apparatus supporting the same. The method may comprise the steps of: entering an RRC state in which cell reselection is not supported; determining whether an MBMS service of interest can be received at a serving frequency for the terminal; and when it is determined that the MBMS service of interest cannot be received at the serving frequency, transmitting an MBMS interest indication message to a network, wherein the terminal may be a terminal not supporting a handover.

Abstract: Provided are a delinking method implemented by a remote UE in a wireless communication system, and a device using said method. The method is characterized by: receiving a disconnect message for disconnecting a link between a relay UE and the remote UE; disconnecting the link on the basis of the disconnect message; and not attempting to establish a link between the remote UE and the relay UE in a UE-specified time section.

Abstract: Disclosed are a terminal operation method and a terminal which: transmit an EMM request message to a network entity; at the same time as transmitting the EMM request message, start a timer for detecting a case in which an EMM response message is not received; receive the EMM response message to which integrity protection is not applied; and wait for an additional EMM response message while operating the timer without stopping the timer.

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: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for performing SCG re-establishment in dual connectivity in wireless communication system, the method comprising: detecting radio link failure on a secondary node, wherein the UE is configured with a master node and the secondary node; and receiving signals from candidates of a new secondary node for obtaining information about which cell is a best candidate on the new secondary node to prepare for radio link failure on the secondary node; and initiating RRC connection re-establishment procedure for recovery from the radio link failure of the secondary node if a cell which is to be a PSCell on a new secondary node is selected in a cell list.

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.
