项目摘要

For many machine-type communication (MTC) based applications, e.g. transmission of pictures, metering or sensor information, bi-directional communication is not necessary, as it is merely used to coordinate and assure the transmission and to perform medium access control. By application of unidirectional (feedback-less) communication from a machine-type-device to a base station, the costs for an increased resource requirement as well as the energy consumption and the integration of a receiver into the MTC-node can be saved. Thus, pure MTC-transmitter networks can be produced on low price and operated on good terms. This is a prerequisite to allow for mass applications of MTC-concepts for the wireless Internet-of-Things.On the contrary, these savings are obtained by the fact, that an MTC node cannot guarantee the target quality-of-service for its data transmission. Furthermore, the network control has no influence on the medium access methods of the individual node. To ensure the application required quality-of-service with a certain reliability, it is important to know the performance limits with respect to the MTC node density as well as their quality-of-service requirements in such an uncoordinated and feedback-less network. Additionally, it is important to optimize these limits with suitably parameterized designs.Thus, the target of this proposal is to determine the performance limits in a feedback-less network based on the joint investigation of the physical layer and medium access control layer. In addition, it targets to design suitable frame structures and mechanisms for service prioritization as well as graceful degradation in overload scenarios.Thereby, the investigation of packet collision effects on the physical layer and their resolution by mechanisms like frame design, channel coding and interleaving, usage of well defined information superposition, multiple transmission with different modes, distributed allocation of the transmit energy in time and frequency domain on transmitter side, as well as single- and multistage successive interference cancelation at receiver side will be investigated. Therefore, on the physical layer the favorable properties of a filterbank-multicarrier (FBMC) modulation scheme with respect to the excellent temporal and spectral transmission energy containment will be used in order to optimally detect and separate unsynchronized packets in the multi-access-channel.The results obtained on the physical layer will be integrated into a network simulator to obtain an assessment of the overall network performance. With these network layer simulations the different quality of service requirements, protocols, node configurations, spatial node distribution as well as the overload behavior will be assessed.Finally a software defined radio testbed will be used to validate the simulation results in a measurement based environment.

对于许多基于机器类型通信（MTC）的应用（例如，图片、计量或传感器信息的传输），双向通信不是必需的，因为它仅用于协调和确保传输以及执行介质访问控制。通过应用从机器类型设备到基站的单向（无反馈）通信，可以节省增加的资源需求的成本以及能量消耗和将接收器集成到MTC节点中。因此，纯MTC发射机网络可以以低价格生产并以良好的条件运行。相反，这些节省是通过MTC节点不能保证其数据传输的目标服务质量的事实获得的。此外，网络控制对各个节点的介质访问方法没有影响。为了确保应用所需的服务质量具有一定的可靠性，重要的是知道关于MTC节点密度的性能限制以及在这种不协调和无反馈的网络中它们的服务质量要求。此外，重要的是要优化这些限制与适当的参数化designs.Thus，本提案的目标是确定在一个无反馈网络的物理层和介质访问控制层的联合调查的基础上的性能限制。此外，它的目标是设计合适的帧结构和机制，以实现业务优先级以及过载情况下的适度降级。因此，研究了物理层上的分组冲突影响及其解决方案，如帧设计，信道编码和交织，使用定义良好的信息叠加，不同模式的多路传输，将研究在发射机侧的时域和频域中的发射能量的分布式分配，以及在接收机侧的单级和多级连续干扰消除。因此，在物理层上的滤波器组多载波（FBMC）调制方案的优良的时间和频谱传输能量的遏制方面的有利属性将被用来以最佳的检测和分离的非同步数据包在多接入信道上获得的结果将被集成到一个网络模拟器，以获得整体网络性能的评估。通过这些网络层仿真，将评估不同的服务质量要求、协议、节点配置、空间节点分布以及过载行为。最后，将使用软件定义的无线电测试床在基于测量的环境中验证仿真结果。
