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.

27. A wireless transmit/receive unit (WTRU) comprising a processor configured, at least in part, to:
-
determine whether the WTRU has D2D data to transmit; and on a condition that the WTRU has D2D data to transmit; determine a set of allowed scheduling assignment (SA) resources, determine an SA resource for transmission of an SA from the set of allowed SA resources, transmit the SA according to a first transmission period using the determined SA resource and according to determined transmission parameters, determine a set of allowed device-to-device (D2D) data resources, select one or more transmission patterns, select one or more transmission parameters, and transmit D2D data over the set of allowed D2D data resources according to a second transmission period using the selected transmission patterns according to the selected transmission parameters. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 36)
