摘要:

设备到设备(D2D)通信对于下一代蜂窝网络的容量和覆盖增强具有巨大潜力。用于D2D通信的潜在节点的数量是直接影响系统容量的重要参数。在本文中,我们推导出蜂窝用户的平均覆盖概率和相应的潜在D2D用户的数量的解析表达式。在这方面,随机几何和泊松点过程的成熟框架已被使用。保留概率已被并入拉普拉斯泛函中以捕获减少的路径损耗和基于最短距离准则的D2D配对。数值结果表明,解析表达式和模拟装置之间的密切匹配。

英文摘要:

Device-to-device (D2D) communication has huge potential for capacity and coverage enhancements for next generation cellular networks. The number of potential nodes for D2D communication is an important parameter that directly impacts the system capacity. In this paper, we derive analytic expression for average coverage probability of cellular user and corresponding number of potential D2D users. In this context, mature framework of stochastic geometry and Poisson point process has been used. The retention probability has been incorporated in Laplace functional to capture reduced path-loss and shortest distance criterion based D2D pairing. The numerical results show a close match between analytic expression and simulation setup.
