QoS-Aware Spectrum Sharing for D2D Communication in Cellular Networks

The continued proliferation of new mobile applications, e.g. autonomous driving, smart cities/homes and tactile internet has increased the number and density of mobile devices requiring wireless connectivity. This creates demand for efficient utilization of the available frequency spectrum apportioned to cellular networks. Device-to-device communication (D2D) as an underlaying transmission within cellular networks presents improved spectral efficiency through spectrum sharing with appropriate management of the resultant interferences. This paper proposes two resource allocation schemes that facilitate the assignment of suitable D2D-pair subsets to share the different cellular users' spectrum in a given cell while concurrently meeting all users' quality of service (QoS) requirements.
