Abstract: Methods and apparatus for performing device-to-device (D2D) discovery are described. A service discovery process may include a discoverable device (e.g., a wireless transmit/receive unit (WTRU)) sending a discovery request, over a wireless connection, for a radio resource for the purpose of performing a transmission for radio frequency (RF) proximity detection for a given service. The WTRU may receive a discovery response including a configuration for RF proximity detection from a network, which configuration may be associated to the service. The configuration for RF proximity may be received by dedicated signaling, (e.g., physical downlink shared channel (PDSCH)), in particular for a discoverable WTRU. The configuration for RF proximity may be received on a broadcast channel, (e.g., a discovery shared channel (DISCH)), in particular for a monitoring WTRU, and may include one or more service identities, each associated with an RF proximity detection configuration, or a validity information and a measurement configuration.

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: Systems, methods, and instrumentalities are provided to implement scheduling for device-to-device (D2D). A WTRU (e.g., a D2D WTRU) may determine whether the WTRU has D2D data to transmit. The WTRU may determine a set of allowed SA resources and/or allowed D2D data resources for transmission of the SA. The WTRU may select an SA resource and/or D2D data resources (e.g., from the set of allowed SA resources and/or D2D data resources) for transmission. The WTRU may select one or more transmission parameters. The WTRU may select one or more transmission patterns. The WTRU may transmit D2D data over the set of allowed D2D resources using the selected transmission patterns and according to the selected transmission parameters.

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: Physical layer processing and procedures for device-to-device (D2D) discovery signal generation and transmission and scheduling of D2D discovery signals are described. Detection and measurement of a D2D discovery signal, D2D signal identity management, and monitoring by a wireless transmit/receive unit (WTRU) of PDCCH for D2D discovery scheduling is described, as is a WTRU that may be configured with a D2D-specific transmission/reception opportunity pattern. The discovery signal may carry a payload for explicit information about user and/or service identity, and may be mapped to physical resources in such a way as to decouple transmission/reception of the discovery signal from downlink operations. A WTRU may measure a D2D discovery signal quality and report to the network.
