Description
Summary:Device-to-device (D2D) communication enables mobile devices to directly communicate with each other without the help of infrastructure and to reuse radio resources within cellular networks. When D2D user equipments (UEs) use the same radio resources for discovery and communication as the cellular network, intercell interference (ICI) may degrade the D2D discovery performance. Therefore, ICI between the cellular network and D2D UEs should be coordinated to avoid performance degradation. In this paper, we evaluate the benefits of time-domain intercell interference coordination (ICIC) approaches in D2D discovery by using almost blank subframes (ABS). Also, we present the benefits of using multi-hop discovery.
