在这篇文章中，研究了3GPP LTE高级蜂窝网络下的设备到设备（D2D）通信，作为对主蜂窝网络具有有限干扰影响的本地服务的使能者。该研究的方法是将D2D通信紧密集成到LTE高级网络中。特别地，我们提出了用于涉及LTE系统架构演进中的过程的D2D通信会话建立和管理的机制。此外，我们提出了基于系统仿真的干扰有限的局部区域的情况下的数值结果。我们的结果表明，D2D通信可以增加在小区区域中观察到的总吞吐量。
In this article device-to-device (D2D) communication underlaying a 3GPP LTE-Advanced cellular network is studied as an enabler of local services with limited interference impact on the primary cellular network. The approach of the study is a tight integration of D2D communication into an LTE-Advanced network. In particular, we propose mechanisms for D2D communication session setup and management involving procedures in the LTE System Architecture Evolution. Moreover, we present numerical results based on system simulations in an interference limited local area scenario. Our results show that D2D communication can increase the total throughput observed in the cell area.
