One of the key technologies in intelligent manufacturing is industry communication. Data collected in processes of supply, manufacture and sale are transferred by using industrial Internet and internet of things (IoT), which satisfied people with speedy, efficient and personalized productions generating requirements. The fifth generation mobile communication (5G) is an enabled technology for realizing industry radio access. While there still exist challenges in ultra-reliable, low latency wireless access and integration of computation and communications. Focus on the requirement and problems in critical mission industry communications, in the project, we will study the theories and technologies of heterogeneous communication for time-sensitive networks (TSN) and the integration mechanisms of wireless and wire, control and communications, computation and networks. The research will cover different layers from physical layer, access layer, networks layer to computation. The detailed content including but not limited the technics and algorithms in wireless bridge and time synchronization for TSN, generalized spatial coding and modulation, precoding/beamforming, and non-coherent receiving in massive MIMO, non-orthogonal multiple access (NOMA), intelligent network resource management. Finally, we will study the technics validities, scheme evaluations by using computer simulations and general hardware platform such as software defined radio (SDR) and software defined networks (SDN). And we will try to realize the algorithms and protocol of seamless service for industry wireless by designing the integration of computing and communication system. The contributions of the research will provide the theoretical and technical supports for new generation of wireless communication and its applications in manufacturing and related standards.
