Description
Summary:Periodic deterministic communication is a well-known traffic pattern in vertical domains and will be supported in 5G for Time Sensitive Communication (TSC). Such a service with typically tight requirements on ultra-reliability and low latency is required for industrial communication to support use cases like discrete automation, process automation and intelligent transport systems. 3GPP has introduced the survival time as a new service parameter in 5G allowing an application to continue for a certain time without an anticipated message. New algorithms can be used in 5G taking advantage on such a fault tolerance allowing a service to "survive" e.g. single packet losses. This paper presents the Alternating Transmission of packets as a new mode for dual connectivity taking advantage of survival time and compares the communication service availability of this mode with single connectivity and packet duplication using dual connectivity.
