Device‐to‐device (D2D) communication is a promising future wireless network technology that establishes a direct link between the devices in close vicinity. Along with the improved end‐to‐end latency and network rate, it also enhances the spectral and power efficiency. Most of the previous works on interference management and resource allocation have considered half‐duplex (HD) D2D systems and have assumed that D2D pairs cannot access more than a single channel at a time and a cellular channel is assigned to at most one D2D pair. In this article, we investigate multiple‐pair‐multiple‐channel (MPMC) allocation scenario over multiple‐input‐multiple‐output‐based full‐duplex D2D networks. The idea is to maximize the aggregate sum data rate of the D2D network by optimal allocation of the resources and maintaining a desired threshold rate for the cellular users. The cross‐tier interferences are intelligently handled by appropriate channel allocation and the co‐tier interferences by proper power allocation. The efficacy of the proposed MPMC algorithm has been evaluated through rigorous simulations, and an appreciably better network rate has been found as compared with the single‐pair‐single‐channel‐based allocation. Moreover, by allowing more users to communicate in tandem, with enhanced average rate, the results also ensure a better opportunity of higher utilization of the scarce licensed cellular spectrum. The presented algorithm has also been compared with random and uniform based allocations and further analyzed in HD‐MPMC communications.

全双工底层设备间通信的多通道分配

设备到设备（D2D）通信是一种有前途的未来无线网络技术，它可以在附近的设备之间建立直接链接。随着端到端延迟和网络速率的改善，它还提高了频谱和功率效率。先前有关干扰管理和资源分配的大多数工作都考虑了半双工（HD）D2D系统，并假定D2D对一次最多只能访问一个信道，并且一个蜂窝信道最多分配给一个D2D对。在本文中，我们研究了基于多输入多输出的全双工D2D网络上的多对多通道（MPMC）分配方案。该想法是通过资源的最佳分配并为蜂窝用户保持期望的阈值速率来最大化D2D网络的总和数据速率。通过适当的信道分配可以智能地处理跨层干扰，而通过适当的功率分配可以智能地处理跨层干扰。通过严格的仿真评估了所提出的MPMC算法的有效性，并且与基于单对单通道的分配相比，发现了更高的网络速率。此外，通过允许更多用户以提高的平均速率进行串联通信，结果还确保了更好地利用稀缺的许可蜂窝频谱的机会。
