DETERMINISTIC6G COTS 5G latency measurements

Measurement setup and dataset overview

The dataset contains the data collected during the latency measurements performed on a COTS 5G system. The 5G network operates in band 78, in TDD mode, with a total of 106 PRBs which occupies 40 MHz of bandwidth. The latency (one-way delay) samples were collected in both uplink and downlink directions using the irtt tool running on the end node (connected to the UE) and the edge node (connected to the 5G gateway). The clocks in the 5G system, end node and edge node were precisely (<200ns) synchronized using Precision Time Protocol (PTP). In addition to recording send and receive timestamps, various network conditions were also recorded for each latency sample.The measurements were carried out in different sessions and for each session, there are about 1M samples in total which are contained in different parquet files corresponding to different rounds (30 mins) per session. Each session corresponds to a combination of direction (uplink or downlink), UE device, a packet interval and payload length, etc. A spreadsheet (COTS5G measurement campaign.xlsx) in this directory contains the information detailed information on the combination for each session.
