Abstract(in English) | With the increasing density of mobile devices, smaller and smaller distance between devices brings some new communication opportunities. Device-to-Device (D2D) communication, which can enable direct connection between the nearby user equipments (UEs), is one of the key technologies in 5G network. In this paper, D2D communication on the unlicensed spectrum, namely, D2D-U, is discussed. D2D-U system performance can be efficiently enhanced by utilizing the unlicensed band which is used by many other popular unlicensed networks such as Wi-Fi and Bluetooth. However, it causes a big impact on the performance of other networks since it is based on the unlicensed band shared with other traditional unlicensed networks. Therefore, the fairness of the coexistence scheme is a key problem for D2D-U. To solve the coexistence problem, two access schemes called Listen Before Talk (LBT) and Duty Cycle Mechanism (DCM) are proposed extensively. D2D users choose the transmission mode from LBT mode and DCM mode. The performance of each mode is discussed in this paper. Furthermore, the problem of how to access the unlicensed band is also be discussed. |
