Abstract: The disclosure herein describes a method and a system for message based communication and failure recovery for FPGA middleware framework. A combination of FPGA and middleware framework provides a high throughput, low latency messaging and can reduce development time as most of the components can be re-used. Further the message based communication architecture built on a FPGA framework performs middleware activities that would enable reliable communication using TCP/UDP between different platforms regardless of their deployment. The proposed FPGA middleware framework provides for reliable communication of UDP based on TCP as well as failure recovery with minimum latency during a failover of an active FPGA framework during its operation, by using a passive FPGA in real-time and dynamic synchronization with the active FPGA.

Abstract: A communication network on board a vehicle is a deterministic switched Ethernet network using virtual links, including a set of subscriber devices and a set of switches in which communications are performed redundantly. To manage redundancy, each data frame transmitted on a virtual link includes a frame number in a numbering field of the frame. The transmitter and/or receiver subscriber devices on the virtual link take into account a length of the numbering field equal to a first predetermined length when the BAG value associated with the virtual link is greater than or equal to a predetermined BAG value, otherwise equal to a second predetermined length greater than the first length.

The UE receives a DL RS in a serving cell of the UE on the first carrier frequency that uses the second signal configuration. The UE adapts the measurement procedure based on the obtained information by adapting a measurement sampling or an instance when the UE shall obtain samples for one or more types of radio measurements.
