Abstract: Provided is a method for a terminal performing a random access procedure in a wireless communication system. The method comprises the steps of: transmitting, to a base station, a first random access preamble corresponding to a system information block-of-interest; receiving, from the base station, a random access response including a random access preamble identifier, wherein the random access preamble identifier indicates a second random access preamble; and determining that the random access response is valid for the terminal if the second random access preamble is included in the same preamble group as the first random access preamble.

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: A user equipment (UE) receives a SPS resource configuration from an eNodeB (eNB), and transmits information related to a semi-persistent scheduling (SPS) activation for a specific logical channel to the eNB. The information may include timing information for the specific logical channel which indicates when a SPS resource for the specific logical channel should be activated. The specific logical channel may correspond to a vehicle-to-everything (V2X) communication.

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.
