Abstract: 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.

Abstract: A method and apparatus for neighbor discovery in a wireless communication system are disclosed. A neighbor seeking wireless transmit/receive unit (WTRU) may search for a first signal to discover neighbor WTRUs for peer-to-peer communication. The WTRU may then receive the first signal. Further, the WTRU may generate a report based on the received first signal. Then, the WTRU may send a second signal carrying the report to a cellular wireless network. The first signal may include a beacon for neighbor discovery or a synchronization signal or both. The report may contain at least one neighbor WTRU identity or at least a portion of a time value or both. Further, the report may contain a counter value, including at least a portion of a time value. The counter value may be based on a time source. In addition, the first signal may be received from a synchronization source.

Abstract: A method for WTRU autonomous resource selection may comprise receiving a TX resource pool for D2D communication from a base station. The WTRU may sense one or more resources of the TX resource pool and determine resources for transmission of control information and D2D data, based on the sensing. The WTRU may then transmit, to another WTRU, the control information and the D2D data on the determined resources.

Abstract: A base station may sense, on a cell using unlicensed spectrum, that the unlicensed spectrum is available for transmission. The base station may transmit, after sensing that the unlicensed spectrum is available, consecutive subframes. Each subframe may include a physical downlink control channel and a physical downlink shared channel.

Abstract: 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.

Abstract: Channel quality may be measured in a device-to-device (D2D) communication network. The D2D communication network may include one or more D2D wireless transmit/receive units (WTRUs), wherein the D2D WTRUs may communicate using a D2D bandwidth. A D2D WTRU may receive a channel measurement resource configuration corresponding to a channel measurement resource. The D2D WTRU may further receive an RS on the channel measurement resource. The D2D WTRU may measure one or more channel state parameters from the channel measurement resource for a part of bandwidth overlapping with a D2D communication bandwidth, when the RS bandwidth is greater than the D2D communication bandwidth. The D2D WTRU may report the channel state parameters to a controlling entity. The controlling entity may configure a D2D frequency allocation between a transmitting device and a receiving device. The D2D frequency allocation may be based on the time averaged measurement.
