设备到设备 (D2D) 通信的优势取决于蜂窝和 D2D 用户之间的智能资源共享。本函旨在优化D2D通信的资源共享，以更好地利用多用户蜂窝系统中的上行链路资源，并保证正常蜂窝通信的质量。尽管存在非凸困难，我们还是提供了全局最优资源共享策略的分析特征，并进一步提出了两种复杂性较低的次优策略。通过数值例子证明了所提出的资源共享策略的优越性。
The benefit of device-to-device (D2D) communication hinges on intelligent resource sharing between cellular and D2D users. This letter aims to optimize resource sharing for D2D communication to better utilize uplink resources in a multi-user cellular system with guaranteed quality of normal cellular communications. Despite the nonconvex difficulty, we provide an analytical characterization of the globally optimal resource sharing strategy, and furthermore propose two suboptimal strategies with less complexity. The superiority of the proposed resource sharing strategies is demonstrated through numerical examples.
