Abstract: A core network to which a cell of a base station can be connected may not be specified to be one. For example, a cell may be connected to an EPC, may be connected to a next-generation core network, or may be connected to both an EPC and a next-generation core network. The base station may transmit core network information relating to a core network to which the cell is connected, on the cell. A user equipment may determine whether to camp on the cell on the basis of the core network information.

Abstract: User equipment may send a channel allocation request (hereinafter referred to as a first channel allocation request) to a network for transmission of data. When the transmission of data has backed off, the user equipment may send a channel allocation request (hereinafter referred to as a second channel allocation request) again for the transmission of data. At this time, the second channel allocation request may be transmitted to the network together with a priority raise request if a remaining timeframe Tremain of an upper timeframe T is smaller than a certain guard time.

Abstract: In a wireless communication system, when a remote user equipment (UE) accesses a network via a relay UE, a base station provides an identifier of a mobility management entity (MME; relay UE MME) of the relay UE to an MME (remote UE MME) of the remote UE. When paging for the remote UE is required while the remote UE is connected to a network via the relay UE, the remote UE MME transmits a request for paging for the remote UE to the relay UE MME, and the relay UE MME transmits a paging notification to the relay UE or starts a paging process for the relay UE through the base station.

Abstract: The present invention relates to a method for transmitting a sidelink signal by a user equipment (UE) in a wireless communication system. The method comprises receiving, from a network, a threshold value for a transmission of the sidelink signal; receiving, from the network, an indicator indicating at least one of a specific UE category and a specific service type allowed to transmit the sidelink signal regardless of the threshold value; if a category of the UE is not the specific UE category and the UE is not operating with the specific service type, measuring quality of a serving cell of the UE; and if the quality of the serving cell is less than the threshold value, transmitting the sidelink signal to a target UE, wherein, if the category of the UE is the specific UE category or the UE is operating with the specific service type, the sidelink signal is transmitted to the target UE regardless of the threshold value.

Abstract: A method for transmitting and receiving data in a wireless communication system, and a device therefor are disclosed. Particularly, a method for transmitting downlink data in a packet data network gateway (P-GW) in a wireless communication system can comprise the steps of: receiving, from an application server, downlink data in which an Internet protocol (IP) header including an IP address of a terminal is encapsulated; removing the IP header from the downlink data; and transmitting, to a serving gateway (S-GW), the downlink data from which the IP header is removed through a bearer identified by the IP address of the terminal, so as to transmit, to the terminal, the downlink data from which the IP header is removed.

Abstract: Provided is a method for making it impossible to track a vehicle performing vehicle-to-everything (V2X) communication through a network. The network may allocate the same IP address to all UEs performing V2X communication. Since the UEs performing V2X communication transmit data using the same IP address, an application server cannot track a vehicle transmitting corresponding data.

Abstract: A method of transmitting data and an eNB are disclosed. The method of transmitting data, which is received from a user equipment and transmitted to a network entity by an eNB, can include the steps of receiving a data packet of the user equipment from a first layer different from an IP layer of the eNB in the IP layer, checking whether or not the data packet corresponds to a data packet transmitted by the first layer using a header of the data packet, if the data packet corresponds to the data packet transmitted by the first layer, adding an IP header selected using a pre-stored mapping table to the data packet, delivering the data packet to which the IP header is added to a second layer corresponding to a lower layer, and transmitting the data packet to which the IP header is added to the network entity.
