在本文中，我们把注意力集中在合作系统的上行链路传输超出了LTE-Advanced倡议。本文首先对单载波频分多址（FDMA）系统的工作原理进行了统一的阐述，比较了局部频分多址、交织频分多址和正交频分多址的异同和优缺点。此外，用户合作和合作的单载波频分多址的哲学进行了审查。他们调查的背景下，不同的拓扑结构，传输模式，资源分配，和信号处理技术应用在继电器。还审查了LTE-Advanced中中继的益处。我们的讨论表明，这些先进的技术最佳地利用资源的协作单载波FDMA系统，这是一个有前途的各种上行链路传输场景的背景下。
In this paper, we focus our attention on the cooperative uplink transmissions of systems beyond the LTE-Advanced initiative. We commence a unified treatment of the principle of single-carrier frequency-division multiple-access (FDMA) and the similarities and dissimilarities, advantages, and weakness of the localized FDMA, the interleaved FDMA, and the orthogonal FDMA systems are compared. Furthermore, the philosophy of both user cooperation and cooperative single-carrier FDMA is reviewed. They are investigated in the context of diverse topologies, transmission modes, resource allocation, and signal processing techniques applied at the relays. Benefits of relaying in LTE-Advanced are also reviewed. Our discussions demonstrate that these advanced techniques optimally exploit the resources in the context of cooperative single-carrier FDMA system, which is a promising enabler for various uplink transmission scenarios.
