- Description
- The emerging 5G networks are intended to enable new feedback control applications, run over multiple wireless interfaces. 5G wireless technologies then need to match the state-of-the- art wired network performance, experienced by present commercial feedback control systems. Fibre-optic circuit switched communication is characterized by constant and very low loop delays, uniform and very high sampling rates, very low error rates and an almost unlimited capacity. The non-trivial challenge is then to meet these characteristics with a packet switched wireless 5G network that may be associated with varying latency, time varying sampling rates, significant error rates and a varying air-interface capacity. The paper contributes with a summary and discussion of basic requirements that need to be in place for successful commercial deployment of feedback controllers using such 5G wireless networks. One key requirement is a need to mitigate the problem of delay skew between different transmission paths. A novel delay skew data flow control algorithm is therefore proposed for 5G dual connectivity. The stability of the controller is analyzed and conditions for global L₂-stability are stated. Test bed results are also reported in the paper, indicating that the delay skew controller can meet the requirements on the delay characteristics of 5G networks.
