Delay Characteristics and Implementation Dependence in Private 5G

Private 5G has high expectations from the manufacturing field, and in addition to various evaluation experiments, it has begun to be introduced to production lines. However, many communications used in production lines have strict requirements for latency, and the expansion of its use in applications that require low latency remains an issue for the future. We are proceeding with the evaluation of upstream communication delay, which is important at manufacturing sites and challenging to optimize. In this paper, we introduce a visualization method of Time Division Duplex (TDD) slot utilization and conduct communication evaluation experiments. As a result, we report that the characteristics of the TDD slot utilization differ depending on the base station.
