dc.description.abstract This work proposes a spectrum selection scheme and a transmit power minimization scheme for a device-to-device (D2D) network cross-laid with a cloud radio access network (CRAN). The D2D communications are allowed as an overlay to the CRAN as well as in the unlicensed industrial, scienti c and medical radio (ISM) band. A link distance based spectrum selection scheme is proposed and closed-form approximations are derived for the link distance thresh- olds to select the operating band of the D2D users. Furthermore, analytical expressions are derived to calculate the minimum required transmit power to achieve a guaranteed level of quality of service in each operating band. The results demonstrate that the proposed scheme achieves nearly 50% power saving compared to a monolithic (purely overlay or purely ISM band) D2D network. Moreover, this work creates an immense space for communication tech- nologies to be wisely managed and utilized by application layer requirements through CRAN architecture. Caching strategies for content replication across end user devices and e ective content delivery strategies can be implemented for forthcoming video streaming applications. en_US
