Abstract:
A method of supporting a group communication by a first user equipment (UE) in a wireless communication system is provided. A communication connection is established with a second UE via a first relay UE. The first UE receives, from a first relay UE, a message requesting a relay connection, the message including first information indicating a current hop count, second information indicating a maximum number of allowed hops, and third information on a capacity profile which indicates a maximum number of allowed subordinated UEs. If a condition is satisfied, the relay connection is provided between the first relay UE and a third UE via a second relay UE, the second relay UE being the first UE. If the condition is not satisfied, the relay connection request is rejected.

Specifically, the present invention is directed to a method of assisting a discovery between hidden wireless nodes and an apparatus therefore, in which the method comprises: receiving, from a first wireless node, a first message including at least one of node identification information and service identification information; receiving, from a second wireless node, a second message including at least one of node identification information and service identification information; conveying, to the second wireless node, at least part of the first message through a third message when one or more conditions are met, wherein the third message includes counting information indicating how many hops the at least part of the first message is conveyed, wherein the one or more condition include that the service information in the first message is matched with the service information in the second message.
Abstract:
Disclosed herein is a communication control method of a vehicle user equipment (UE) for controlling vehicle-to-everything (V2X) message transmission between vehicle UEs through a V2X service in a wireless communication system. The communication control method of the vehicle UE includes receiving a V2X message from a first external vehicle UE, determining whether the V2X message is transmitted to a second external vehicle UE located in a coverage area of the vehicle UE, based on relaying information indicating whether the V2X message is relayed, and transmitting the V2X message to the second external vehicle UE, upon determining that the V2X message is transmitted to the second external vehicle UE. The relaying information includes at least one of active status information, relay probability information or residual life information.
Abstract:
Disclosed herein is a method for transmitting and receiving data using an LTE-WLAN aggregation in a wireless communication system. The method performed by a terminal comprises transmitting status information to an access point (AP), receiving a specific packet for indicating an activation of the wireless LAN module from the AP, activating the wireless LAN module based on the specific packet, transmitting a response message indicating that the wireless LAN module is activated in response to the specific packet to the AP, and receiving downlink data through an unlicensed spectrum using the LTE-WLAN aggregation from AP.
Abstract:
In a wireless communication system of the present invention, a user equipment (UE) can receive mapping information for each of a plurality of connection categories. The UE can receive barring information for the plurality of connection categories. The UE can determine whether to perform a connection attempt to a network on the basis of the barring information and a connection category to which UE data belongs according to the mapping information.
Abstract:
A disclosure of the present specification provides a network access blocking method performed by a user equipment. The method may comprise the steps of: receiving application specific congestion control for data communication (ACDC) blocking information and access class barring (ACB) blocking information; determining the category of an application being executed according to a network access attempt by the application; performing an ACDC blocking check on the basis of the determined category and the received ACDC blocking information. Here, when the network access attempt by the application is not blocked as a result of the ACDC blocking check, an ACB blocking check on the basis of the ACB blocking information may be skipped.
Abstract:
The present invention provides methods for supporting a public transportation by using a Vehicle to Everything (V2X) at a Passenger Control Center (PCC) in a wireless access system. One of the methods comprising steps of tracking taxis in a coverage of the PCC in order to support the public transportation; transmitting a first Vehicle to Infrastructure (V2I) or Vehicle to Network (V2N) message triggering a public transportation service to the tracked taxis; receiving a second V2I or V2N message from one or more taxis including location information of each of the taxis; collecting traffic situation information on an area including the PCC; deciding candidate taxis based on the location information and the traffic situation information; and transmitting a third V2I or V2N message indicating pick up passengers at a specific taxi stand to the candidate taxis, wherein each of the taxis is a vehicle user equipment (VUE).
Abstract:
The present invention provides methods and apparatus for gathering location information of a vehicular user equipment (VUE). In one aspect of the present invention, a method for gathering location information in a wireless access system supporting vehicle to everything (V2X) service, the method performed by a vehicular user equipment (VUE) and comprising steps of receiving a Tracking Service Request message including a V2X tracking service indication field indicating tracking service is triggered or not and an identifier of the VUE; and transmitting a Tracking Service Response message including location information of the VUE in response to the Tracking Service Request message, wherein the location information includes a location information field indicating a location coordinate of the VUE, a time field indicating current time and time zone information corresponding to the location information field, and a fuel level field indicating fuel level of the VUE.
Abstract:
The present invention relates to a method and apparatus for an adaptive barring control for a Mobile Originating Short Message Service (MO-SMS). In one aspect of the present invention, a method for controlling an adaptive access class barring in a wireless access system, the method is performed by an enhanced Node-B (eNB) and comprises steps of estimating a SMS load, a MMTEL video load, and a MMTEL voice load on a cell of the eNB; generating a congestion level based on the MMTEL video load and the MMTEL voice load; determining an indication bit by comparing the SMS load with threshold values for the congestion level; and broadcasting an system information block (SIB) message including the indication bit. In this case, the indication bit indicates an open barring, a LessCongested or a MoreCongested to support the adaptive barring control.
Abstract:
The present invention relates to a method and apparatus for indicating time zone changes. In one aspect of the present invention, a method for indicating a time zone change is performed by a user equipment (UE) and comprises steps of: receiving, from a first eNode-B (eNB) a first Mobility Management (MM) information message including first time zone information; storing the first time zone information and displaying a first time on a screen based on the first time zone information; moving from an area of the first eNB to an area of a second eNB; receiving, from the second eNB a second MM information message including second time zone information; checking a time zone is changed or not by comparing the first time zone information with the second time zone information; and displaying a second time according to the second time zone information on the screen when the time zone is changed.
