Spatial Diversity to Support URLLC through Unlicensed Spectrum in Industrial Wireless Network Systems

This paper proposes a method to enable efficient communication service for the fifth generation (5G) wireless communication and it addresses performance requirements for better as well as faster broadband in unlicensed spectrum. The coexistence of the unlicensed spectrum with the licensed spectrum is the major importance to prevent the lack of communication means for coordination and negotiation, offering capacity boost to the licensed spectrum. Subsequently, the spatial diversity technique was carried out to enable ultra-reliable and achieve minimum transmission delay. A reliability is observed in terms of throughput simulation results conducted under different modulation coding schemes (MCSs). Accordingly, the increased number of spatial degrees of freedom presented in both base station (network) and terminals (transmitter and receiver) automatically improves the system performance. Hence, it is a contributor to ultra-reliable and low latency communication (URLLC). This conveys to boost the performance to meet latency-reliability requirements of the system.
