Title : D2D: Research Trend and Future Perspective
Abstract :

As driven by the proliferous development of media-hungry handheld devices and online applications, there has been an unprecedented consumer demand for faster and cheaper mobile broadband usage. Given the impossibility of meeting this demand by adding spectrum, researchers around the whole world are bending over backwards to squeeze out more data bits from the limited available frequency resources. Among various efforts towards this end, device-to-device (D2D) communication which allows mobile UEs in proximity to communicate directly via licensed/unlicensed band with/without the support from the operator, has gained intensive research interests from academia, industry, and standard bodies. In this talk, we present the opportunities for D2D to improve system capacity, enhance spectral efficiency, and increase coverage and connectivity, and identify the new challenges to co-existence and network management. In particular, we introduce the applications of D2D for traffic relaying in disaster relief, and for load balancing in LTE-Advanced networks. Finally, we outline some research directions in the future wireless networks.
