预期诸如高级IMT的未来蜂窝网络允许底层的直接设备到设备（D2D）通信，以用于例如丰富多媒体本地服务的频谱高效支持。在蜂窝网络中启用D2D链路由于其可能对蜂窝网络造成的潜在严重干扰而在无线电资源管理中提出了挑战。我们提出了一种实用和有效的方案，用于在基站处生成蜂窝和D2D终端之间的干扰的本地感知，然后利用蜂窝网络中固有的多用户分集来最小化干扰。系统仿真表明，使用所提出的方案可以获得蜂窝和D2D性能的实质性增益。
Future cellular networks such as IMT-Advanced are expected to allow underlaying direct Device-to-Device (D2D) communication for spectrally efficient support of e.g. rich multimedia local services. Enabling D2D links in a cellular network presents a challenge in radio resource management due to the potentially severe interference it may cause to the cellular network. We propose a practical and efficient scheme for generating local awareness of the interference between the cellular and D2D terminals at the base station, which then exploits the multiuser diversity inherent in the cellular network to minimize the interference. System simulations demonstrate that substantial gains in cellular and D2D performance can be obtained using the proposed scheme.
