Abstract

Full Duplex (FD) communication has potential to double Spectral Efficiency (SE). Due to realization difficulties, hybrid cellular networks that limit FD capability to base stations and continue with legacy Half Duplex (HD) User Equipments (UEs) have been proposed. Such a hybrid network shares frequencies within groups of UEs to maximize SE. In this letter, we propose perfect UE grouping algorithms that maximize frequency sharing within UE groups. Specifically, novel weighted grouping outperforms traditional unweighted and pairing approaches and achieves close-to-doubling sum SE over HD networks. Since our proposed algorithms are of polynomial-time complexity, they are realizable for next-generation cellular systems.

全双工蜂窝网络中频率共享的完美 UE 分组

全双工（FD）通信具有将频谱效率（SE）提高一倍的潜力。由于实现上的困难，有人提出了混合蜂窝网络，即限制基站的全双工能力，继续使用传统的半双工（HD）用户设备（UE）。这种混合网络在 UE 组内共享频率，以最大限度地提高 SE。在这封信中，我们提出了完美的 UE 分组算法，使 UE 组内的频率共享最大化。具体来说，新颖的加权分组方法优于传统的非加权和配对方法，在高清网络中实现了接近两倍的 SE 总和。由于我们提出的算法具有多项式时间复杂性，因此可用于下一代蜂窝系统。
