Industry is presently on the threshold to the forth industrial revolution. In the future, industrial production will be marked by strong individualization of products and a highly flexible (large-series) production. In order to achieve this, it is planned to integrate Cyber-physical systems (CPS) into the production and thus form, together with warehouse systems, a Smart Factory. In intelligent factories, different information must be shared between local and mobile CPSs - more and more wireless. For this reason, it is of vital importance to investigate, how communication between CPSs will be possible in consideration of industrial communication requirements. In order to allow peripheral CPSs (e.g. automated guided vehicle) to interact with production cells, the use of wireless communication on cell level is pursued. So far, there are no adequate wireless communication standards for the cell level in regard to data rate, synchronism, reaction time, availability and reliability. The required data rate is only provided in case of the wireless communication standards Wi-Fi, Wimax and LTE-Advanced. Only Wimax and LTE Advanced use proprietary frequency bands, nevertheless LTE Advanced presents a larger data rate and a smaller reaction time and is, therefore, better suited for the use on cell level. However, LTE-Advanced has no mechanisms to allow for the synchronization of tasks in different communicating devices. An extension of LTE Advanced shall help to achieve this objective, namely by implementing synchronization and communication stabilizing mechanisms. As the two missing parameters, availability and reliability, are guaranteed by the proprietary frequency used, it would then be possible to reach the stringent requirements of the cell level communication and then to enable the implementation of Industry 4.0 infrastructure.

工业目前正处于第四次工业革命的门槛上。未来工业生产将以产品高度个性化和高度柔性化(大系列)生产为标志。为了实现这一目标，计划将网络物理系统(CP)整合到生产中，从而与仓库系统一起形成智能工厂。在智能工厂中，不同的信息必须在本地和移动CPSS之间共享-越来越多的无线。因此，在考虑到工业通信需求的情况下，研究如何在CPSS之间进行通信是至关重要的。为了允许外围CPSS(例如自动导引车)与生产单元交互，追求在单元级别上使用无线通信。到目前为止，在数据速率、同步性、反应时间、可用性和可靠性方面，还没有针对信元级的适当的无线通信标准。仅在无线通信标准Wi-Fi、Wimax和LTE-Advanced的情况下才提供所需的数据速率。只有Wimax和LTE Advanced使用专有频段，然而LTE Advanced提供了更大的数据速率和更短的反应时间，因此更适合在小区级别使用。然而，LTE-Advanced没有允许不同通信设备中的任务同步的机制。LTE Advanced的扩展将有助于实现这一目标，即通过实施同步和通信稳定机制。由于可用性和可靠性这两个缺失的参数是由所使用的专有频率保证的，因此可以达到信元级通信的严格要求，然后实现Industry 4.0基础设施。
