1. A method of operating a user equipment, UE, for device-to-device, D2D, transmission of a channel state information, CSI, report and/or a CSI reference signal, CSI-RS, the method comprising:
identifying a CSI selection window containing candidate resources for use in D2D transmission of the CSI report and/or CSI-RS;
identifying a data selection window containing candidate resources for use in D2D transmission of data and which at least partially overlaps a region of the CSI selection window; and
controlling transmission of data and the CSI report and/or CSI-RS to use at least one resource that is selected within the overlapping region of the CSI selection window and the data selection window, wherein resource selection for the D2D transmission of both the CSI report and/or CSI reference signal and the data is conducted simultaneously, wherein the CSI selection window includes a first time interval that differs from a second time interval that corresponds to the data selection window.
