Abstract:
Disclosed herein is a method for tracking a location in vehicle-to-X (V2X) communication in a wireless communication system. The method includes receiving a second message from a second network entity, checking whether the second vehicle UE is served by a cellular network, identifying its own ID included in the received second message, and transmitting a third message including second control information related to the location of the second vehicle UE to the second network entity if the second vehicle UE is served by the cellular network.
Abstract:
The present disclosure is a method for transmitting and receiving a signal in a wireless communication system supporting a zone-based communication, the method performed in a drone, comprising: receiving a plurality of control signals from one or more base stations included in at least one cluster; combining the received control signals; and transmitting data to one or more base stations or perform a specific operation based on the combined control signal, and wherein the at least one cluster is included in a zone defined as a predetermined set of base stations for the drone.
Abstract:
Disclosed herein is a method for transmitting and receiving a signal in a wireless communication system supporting a Relay UE. The method performed by the Relay UE comprises determining whether or not to serve a connection request for a Remote UE using at least one of first control information related to a current state of the Relay UE, second control information indicating a type of traffic to be supported, and third information indicating a current load state of the Relay UE; and transmitting the determination result to at least one Remote UE.
Abstract:
A method for beamforming training and a device using the same are provided. The device receives, from an access point (AP), a plurality of beacon frames for a sector sweep at a beacon transmission interval (BTI). At least one of the plurality of beacon frames includes an overload indicator indicating an overload state. The device determines whether to initiate a random backoff in an association beamforming training (A-BFT) following the BTI, on the basis of the overload indicator.
Abstract:
Disclosed herein is a method for transmitting a signal in a wireless communication system supporting a Relay UE. The method performed by the Relay UE comprises transitioning to a Remote UE mode; monitoring a channel through which a specific Relay UE transmits a signal in the Remote UE mode; receiving relay-related system information including indication information indicating that state information of a neighbor Relay UE is transmitted for each specific period through the monitoring; receiving state information of the neighbor Relay UE from the neighbor Relay UE based on the indication information; transmitting a connection request for transmitting and receiving the signal to the neighbor Relay UE; and receiving a response to the connection request from the neighbor Relay UE.
Abstract:
Disclosed herein is a method for receiving a warning message in a wireless communication system.The method performed by a terminal comprises receiving, from a base station, first control information indicating whether or not a use of a pre-defined string (PDS) set including one or more PDSs used for a Public Warning System (PWS) is enabled; receiving, from the base station, second control information associated with a configuration of the PDS set; receiving, from the base station, the warning message; and outputting an alarm information based on the received warning message.
Abstract:
The present invention is directed to a wireless communication system. Specifically, the present invention is directed to a method of controlling network access and an apparatus therefore, wherein the method comprises: receiving a first field for indicating network overload situation and a second field for indicating a network access priority; and receiving at least one of a N-bit field for indicating a first back-off window and a M-bit field for indicating a second back-off window, wherein if a configured priority is equal to or higher than the network access priority, a random access (RA) procedure is performed using the first back-off window, wherein if the configured priority is lower than the network access priority, the RA procedure is selectively barred or performed using at least one of the first back-off window and the second back-off window.
Abstract:
The present invention is directed to a method and an apparatus for use in a wireless communication system. Specifically, the present invention is directed to a method and an apparatus of performing a network access procedure, the method comprising: receiving system information including Application-based (APP-based) information set, wherein the APP-based information set includes one or more APP-based information subsets, and each APP-based information subset is used to control network access per application; and performing the network access procedure under control of APP-based information subset corresponding to an application that causes the network access procedure.
Abstract:
The present invention is directed to a method and an apparatus for use in a wireless communication system. Specifically, the present invention is directed to a method of performing a discovery procedure for a ProSe and an apparatus therefore, in which the method comprises: receiving first resource allocation information for plural ProSe channels from a base station via a broadcast signal; sensing the plural ProSe channels; transmitting a sensing result for the plural ProSe channels to the base station; receiving second resource allocation information indicating one of the plural ProSe channels from the base station via a unicast signal; and transmitting a discovery signal via the ProSe channel indicated by the second resource allocation information.
Abstract:
The present invention is directed to a method and an apparatus for use in a wireless communication system. Specifically, the present invention is directed to a method and an apparatus of performing a procedure of forming a Public Safety Group (PSG) for a Proximity-based Service (ProSe), the method comprising: receiving first information indicating one or more class identifiers as a part of system information from a network; determining whether any one of one or more configured class identifiers is indicated to be used as a specific class identifier for the PSG formation based on the first information in the system in formation; and performing a procedure to discover one or more neighboring user equipments for PSG formation using the specific identifier when any one of the one or more configured class identifiers are indicated as the specific class identifier for the PSG information.
