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:
A user equipment (UE) may receive or transmit a protocol data unit (PDU). The PDU includes a service data unit (SDU) type field. The SDU type field may be set to a value indicating a vehicle-to-everything (V2X) type. When the SDU type field is set to a value indicating a V2X type, the PDU may include an additional field indicating an application or protocol type for data of an SDU in the PDU.
Abstract:
One embodiment of the present invention, with respect to a call receiving method of a UE in a wireless communication system, a call receiving method of a UE comprises the steps of: establishing a one-to-one connection with a relay UE; transmitting an SIP register message including information pertaining to an IMS registration cancellation of the relay UE to an SIP server; and receiving a call from the SIP server, wherein when a connection between the UE and the relay UE is cancelled, the relay UE is IMS registered.
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:
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 is provided for transmitting, by a user equipment (UE) with which a primary cell and at least one secondary cell are configured, power headroom (PH) information in a wireless communication system. The PH information is generated and transmitted to a base station. The PH information includes a first field including a plurality of indicators, each of the plurality of indicators indicating the presence of a second field indicating a PH level of a corresponding secondary cell. The PH information includes a type-2 PH field which is always included for the primary cell together with a type-1 PH field.
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 for receiving a multimedia broadcast multicast service (MBMS) by a user equipment (UE) in a wireless communication system; the UE therefore; a method for transmitting an MBMS by a base station (BS) in a wireless communication system; and the BS therefore are discussed. The method for receiving an MBMS by a UE according to one embodiment includes transmitting one or more system information blocks (SIBs); receiving a first MBMS interest indication message indicating whether MBMS reception is prioritized above unicast reception, when a predetermined SIB related to MBMS service continuity is included in the one or more SIBs; and receiving a second MBMS interest indication message according to a change of priority between the MBMS reception and the unicast reception.
Abstract:
The present invention relates to a wireless communication system, and more particularly, to a method and an apparatus for processing a NAS signaling request. A method for performing a non-access stratum (NAS) signaling process by means of a terminal in a wireless communication system according to one embodiment of the present invention comprises: a step of receiving a first message that includes information indicating a network failure from a network node of a first network; a step of starting a timer relating to a network selection; and a step of selecting a second network from among network candidates excluding the first network during the operation of the timer relating to a network selection.
Abstract:
A method and a user equipment (UE) are described for transmitting power headroom (PH) information. The UE generates PH information, and transmits the PH information to a base station. The PH information includes a first field including a plurality of indicators, each of the plurality of indicators indicating the presence of a second field indicating a PH level of a corresponding secondary cell (SCell). The PH information further includes a type-1 PH field and a type-2 PH field for a primary cell (PCell). Each of the plurality of indicators is set to 0 or 1. An indicator, which has been set to 1, indicates that the second field exists for the corresponding SCell, and an indicator, which has been set to 0, indicates that the second field does not exist for the corresponding SCell.
