In heterogeneous networks of low power Pico Base Station (PBS) overlaid with Macro Base Station (MBS), cell range expansion (CRE) which add a positive bias in PBS for cell association is proposed to offload user equipments (UEs) to PBSs. In this way UEs in CRE region that associated to PBS with weak signal power may experience strong cross-tier interference from MBS. To manage this interference, almost...
Device-to-device (D2D) communication is envisioned as a promising technology in future cellular networks. In this paper, we investigate the delay-aware resource allocation and power control algorithm for delay-sensitive D2D communications underlaying cellular networks. With the objective to minimize the average delay and average drop rate, we formulate the optimization problem as an infinite horizon...
Device to device (D2D) communication is expected to be an important aspect in future 5G communication systems. To this end, D2D has been identified as an important topic in the EU flagship project METIS, wherein commercial D2D use cases are also considered. In principle, direct D2D communication offers the double benefit of low latency and high data rate at the same time. Interference mitigation and...
