摘要： A wireless transmit/receive unit (WTRU) may receive from a network resource allocation information for device to device (D2D) communication. The WTRU may select, from the received resource allocation information for a transmission time interval (TTI), resources for a D2D channel. The WTRU may transmit, with use of the selected resources, data directly to another WTRU.

摘要： A wireless transmit/receive unit (WTRU) may receive discovery related configuration information that includes discovery filtering information and information for a non-long term evolution radio access technology (non-LTE RAT). The WTRU may monitor a device to device (D2D) communication interface on the non-LTE RAT based on the discovery filtering information and send a report that includes information associated with the discovery filtering information. The WTRU may receive a message to allow the WTRU to establish a D2D communication link with another WTRU using the non-LTE RAT.

摘要： A method and apparatus for advanced topology (AT) policy management for direct communication between wireless transmit/receive units (WTRUs) is described. A WTRU configured to communicate directly with at least one other WTRU in an AT mode of operation includes a memory, a central processing unit and an AT policy unit that is separate from the CPU. The AT policy unit is configured to store at least one AT policy in the memory, activate and de-activate an AT application that runs the AT mode of operation based on the at least one AT policy stored in the memory, receive data from at least one application within the WTRU other than the AT application, and control the at least one application within the WTRU other than the AT application based on the at least one AT policy stored in the memory.

摘要： A method and apparatus for cross link (XL) establishment are disclosed. In the method and apparatus, a XL between a terminal wireless transmit/receive unit (T-WTRU) and a helper WTRU (H-WTRU) is established. The T-WTRU and the H-WTRU may be configured to operate in a plurality of RRC states and a plurality of RRC substates. To establish the XL, neighbor discovery, association information exchange, and a H-WTRU selection may be performed. Radio resource control (RRC) configuration of the T-WTRU and the H-WTRU may also be performed. In the method and apparatus, coverage for a T-WTRU may be handed over between a network and a H-WTRU or between two H-WTRUs.

摘要： A method performed by a wireless transmit/receive unit (WTRU) may include sending, to a network, a registration message indicating the WTRU is capable of device-to-device (D2D) communication and sending a request for assistance in discovering at least one other WTRU in proximity to the WTRU. The method may include receiving, from the network, in response to the request for assistance in discovering the at least one other WTRU, assistance information including one or more of a unique identifier or filtering information. The method may include performing, using the assistance information, a device discovery procedure to discover the at least one other WTRU, wherein the device discovery procedure comprises at least one of: monitoring for signals from the at least one other WTRU using the assistance information, or sending a discovery announcement based on the assistance information and transmitting application data directly to the at least one other WTRU.

摘要： A method and apparatus are described for supporting a two-stage device-to-device (D2D) discovery using a D2D interworking function (IWF). A D2D IWF component may be configured to perform mapping between an application running on an application server and a third generation partnership project (3GPP) network, and provide a set of application programming interfaces (APIs) to allow discovery to be provided as a service to D2D applications. An application identifier may be mapped to a 3GPP identifier. Further, a method and apparatus are described for performing client-server discovery. A first wireless transmit/receive unit (WTRU) may be configured for a listen-only operation, and a second WTRU may be configured to transmit beacons. The first and second WTRUs may perform a radio access network (RAN) discovery procedure at an access stratum (AS) layer. A method and apparatus for performing charging for D2D service using a D2D IWF are also described.

摘要： Systems and methods for enabling proximity services to be delivered as part of an application service and/or for providing tailored services and/or a differential quality of service (QoS) to a flow may be disclosed. For example, a temporary service name between an application and a server such as a D2D server may be established such that a UE and/or network may execute such a service at a later time without later involvement by the application and/or without exchanging credentials for the application with the network and vice versa.
