Abstract:
Provided are a method for device-to-device (D2D) communication performed by terminals in a wireless communication system, and terminals for supporting the method. The method comprises: receiving resource assignment information for D2D communication; and performing the D2D communication by using resources indicated by the resource assignment information, wherein the validity of the resource assignment information is determined on the basis of the type of the cell from which the terminals receive services, and the D2D communication is performed only if the resource assignment information is valid.
Abstract:
A method and apparatus for configuring radio resources for a device-to-device (D2D) operation in a wireless communication system is provided. A user equipment (UE) configures two types of radio resources which include a first type of radio resources and a second type of radio resources. The first type of radio resources is used for the D2D communication, and the second type of radio resources is used for communication between the UE and a network. Then, the UE performs the D2D communication by using the first type of radio resources upon receiving a D2D radio network temporary identifier (D-RNTI) for the D2D communication.
Abstract:
A method and apparatus for transmitting an indication for a device-to-device (D2D) operation in a wireless communication system is provided. A user equipment (UE) transmits an indication indicating that the UE is interested to perform a D2D operation. The D2D operation may include reception/transmission of a D2D discovery signal/D2D communication data.
Abstract:
A disclosure of the present specification provides a method for executing a service request procedure from a user equipment (UE). The method may comprise the steps of: receiving skip information for an access class barring (ACB) inspection; if a service request procedure must be executed for any one from among a multimedia telephony (MMTEL) service and a short message service (SMS), then confirming the skip information; and, if the skip information is configured to indicate that the ACB inspection should be skipped for any one from among the MMTEL service and SMS, then transmitting a radio resource control (RRC) connection request message for the service request procedure.
Abstract:
A disclosure of the present specification provides a method for executing a service request procedure from a user equipment (UE). The method may comprise the steps of: a lower layer of a UE blocking access of an originating call due to access class barring (ACB); an NAS layer of the UE receiving a start indication from an upper layer due to a request for uplink data; and, if the lower layer has indicated that access was blocked for the originating call but the NAS layer has received the start indication, then the NAS layer commencing the service request procedure.
Abstract:
Provided are a method whereby terminals transmit device-to-device (D2D) signals in a wireless communication system, and terminals for supporting the method. The method comprises: identifying multiple resource pools capable of transmitting D2D signals; and selecting a particular resource pool from among the multiple resource pools, wherein the D2D signals are transmitted by using the resources of the selected particular resource pool.
Abstract:
A method and apparatus for performing device-to-device (D2D) discovery in a wireless communication system is provided. A first user equipment (UE), which supports proximity services (ProSe), transmits a request of D2D discovery to a network, and receives information on a second UE, which supports the ProSe and is located in proximity of the first UE, and information on D2D discovery signaling. The first UE performs D2D discovery based on the received information on the second UE and information on D2D discovery signaling.
Abstract:
A method and an apparatus for steering traffic in a wireless communication system are provided. User equipment (UE) within a visitor public land mobile network (VPLMN) transmits to a network, access network discovery and selection functions (ANDSF)-related information including information on at least a home ANDSF (H-ANDSF) set by a home PLMN (HPLMN) and/or a visitor ANDSF (V-ANDSF) set by the VPLMN. The UE receives, from the network, the traffic steering information generated through the network on the basis of the ANDSF-related information, and steers the traffic on the basis of the received traffic steering information.
Abstract:
A method and apparatus for performing access control in a wireless communication is provided. A user equipment (UE) receives an access control parameter and a backoff parameter from a network, and determines whether to apply the access control parameter or the backoff parameter based on applications. If it is determined to apply the access control parameter, the UE applies the access control parameter instead of the backoff parameter.
Abstract:
Provided are a method and a wireless device for reporting proxy information in a wireless communication system. As the wireless device enters the proximity of a first target cell on a target frequency, the wireless device reports first proxy information indicating entering the proximity to a serving cell. Before the wireless device transmits proxy information indicating leaving the proximity after reporting the first proxy information, the wireless device does not report proxy information on entering the proximity of any other target cell on the target frequency.
