Abstract
Absolute Time Synchronization (TS) over the air interface has been introduced with 3GPP 5G NR Release 16 which enables a wide set of applications requiring accurate time-of-day service. In this paper, we present a detailed evaluation of the achievable accuracy of Release 16 TS service considering user equipment (UE) impairments, multipath components, and deployment parameters. Additionally, we propose alternative reference signal and measuring settings required for different channel realizations and environments to meet requirements from a plethora of regulatory, commercial, and 5G industrial use cases. It is shown that wideband channel state information reference signal better supports TS for control to control use case at up to 60m of cell size in comparison to 10m if synchronization signal block is used for TS. The evaluation can be used as guidelines for reference signal configurations and how often the absolute timestamps should be delivered to the UE over the air interface for different deployment scenarios.
