| Abstract | ||||
| This work presents a tractable approach to enabling D2D uplink underlay in cellular networks in order to improve the spatial frequency reuse and to enhance the performance of cellular networks. In general, the cellular-to-D2D interference needs to be restricted to maintain a target performance level of the networks. In this respect, we propose an optimally quantized transmission power control and interpolation schemes for cellular users to limit the interference from them on D2D users. On the other hand, for the interference induced from D2D transmissions on the base station's receiver a concentric cell structure in conjunction with an orthogonal resource assignment scheme is developed. The proposed schemes exploit the assistance of a localization system developed to estimate the D2D and cellular user's spatial separations. Simulation results show that the proposed schemes can bring less interference and, at the same time, can easily be implemented in real cellular networks without the need of further standardization work. | ||||
