Abstract
In this paper, we analyze the capacity of future cellular networks with a Device-to-Device (D2D) underlay reusing cellular uplink radio resources. We consider two resource reuse strategies and observe the behavior of the two-tier network with respect to the per-user transport capacity in both network layers. Our results indicate that the trend of network infrastructure densification and the prioritization of cellular communication over direct links might hinder D2D communication. Hence, careful system design is essential in order to enable additional D2D-based (e.g., automotive) applications in the next-generation cellular networks.
