Alternating packet transmission in dual connectivity for periodic deterministic communication utilising survival time
16 June 2020
Periodic deterministic communication is a wellknown communication pattern in vertical domains and shall be supported in 5G for Time Sensitive Communication (TSC). Such a service with typically strong 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. The introduction of the survival time as a new service parameter allows the introduction of new algorithms in the 5G system. This paper presents the alternating packet transmission 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.
