Abstract

In embodiments, apparatuses, methods, and storage media may be described for allocating radio resources to a user equipment (UE) for device to device (D2D) transmission. Specifically, the UE may be configured to predict cellular interference to one or more cellular transmissions in a cell that may be caused by the transmission of a D2D signal. Based on that predicted interference, the UE may identify one or more radio resources in for the D2D transmission.
