Abstract:
The high demand for frequency resources due to the ever increasing number of devices in cellular networks requires new approaches that maximize the spectral efficiency. Spectrum sharing is seen as an enabler to improve the overall spectral efficiency. Device to device (D2D) communication as an underlaying network to the cellular networks presents spectral efficiency improvements through the increased sharing of the cellular spectrum. In this paper, we analyze cell spectral efficiency and propose a uniform interference power (UIP) resource allocation scheme that reuses the cellular uplink spectrum resources for D2D communication. Using the base station (BS) to control the transmit power of all user terminals (UTs), the UIP scheme ensures that each of the D2D users reusing cellular resources contributes the same interference power at the BS without negatively impacting the cellular users. Our results show zero outage probability of the cellular user while the cell spectral efficiency is enhanced by up to 20 times when compared with the conventional cellular communication mode where no resource reuse within the cell is allowed.
