Context-Awareness for Device-to-Device Resource Allocation

The paper investigates a context-aware approach to radio resource allocation for device-to-device (D2D) communication, focusing on solutions that leverage information on user equipment location and environmental features, such as building layouts. A system enabling direct communication by sharing uplink resources with cellular users is considered. Such a system introduces mutual interference between direct and cellular communications, posing challenges related to maintaining adequate performance levels. To address these challenges, various context-based resource allocation methods are analyzed, aiming to optimize spectral efficiency and minimize interference. The study explores the impact that different D2D device densities exert on overall network performance measured by means of spectral efficiency and the signal-to-interference ratio.
