In this demonstration, we consider secondary spectrum usage by D2D users in cellular network. Secondary usage is allowed if primary users are not impacted. We show how a Base Station (BS) creates new D2D communication opportunities on uplink resources by enabling Interference Cancellation (IC). BS can apply single-state IC when the D2D signal is strong enough. This can occur when the D2D transmitter is located near to the BS or when the BS explicitly orders D2D transmitter to increase its transmission power. This demonstration shows that D2D user successfully streams a video without influencing the cellular user's live video streaming on the same spectrum resource. The demonstration is based on software defined radio platform with Universal Software Radio Peripherals (USRP) as the hardware front-ends.
