This demonstration presents dynamic spectrum use by an overlay Device-to-Device (D2D) connection in a Heterogeneous Network (HetNet) environment. D2D devices can reuse the uplink resources of the cellular network. In a HetNet, the cellular users should be protected from excessive interference from the D2D connections. This is especially so for small cells as D2D transmitters may come arbitrarily close to the small cell base stations. We demonstrate how the cellular traffic can be protected by prohibiting the D2D reuse close to the cellular base stations by measuring the signal strength at the D2D devices. Our measurement results show that in the case of small cells, fast changes in the signal strength proposes challenges to the decision making algorithm. A demonstration with a software defined radio TD-LTE platform is shown.
