Abstract
随着移动通信设备数量的不断增长,频谱资源匮乏问题日趋明显,基站负载日益增加,邻近距离通信无时无刻不在身边出现。而设备到设备间的直接通信技术(Device-to-Device,D2D)能给邻近距离业务传输提供更好的用户体验,成为了下一代移动通信网络5G的关键技术之一。与传统的蜂窝通信相比,D2D通信能够为基站(BS)和核心网提供负载分流,具有降低设备功耗,减少传输延时,提高吞吐量等优势,因此广受关注。 D2D通信使得设备间的数据传输可以避开BS而直接在设备间直接进行,并通过复用蜂窝授权频段从而提高频谱利用率,因而成为一种重要的近场通信技术。本文针对蜂窝用户(CUE)与D2D用户(DUE)组成...
 
With the explosive increasement of mobile user equipments, the scarcity of spectrum resource becomes more serious and the burden of base station (BS) is also getting heavier. Meanwhile, the proximity-based communication resides in each place. As a result, D2D communication receives great attentions and becomes one of the promising technologies in 5G networks due to its advantages in proximity-base...
