The publisher just completed its seventeenth 5G benchmark study, this time with a focus on 5G NR scheduler efficiency with DSS or 5G NR in a dedicated radio channel and how it compares with LTE scheduler efficiency.
They tested Ericsson (Verizon DSS in Band n5) and Nokia (T-Mobile dedicated bearer in Band n71). A higher resolution version is available upon request or it can be downloaded from the SRG website.
Highlights of the Report include the following:
By leveraging the Sanjole test equipment they were able to collect sector-level performance data in the networks tested, including the LTE anchor bands and the 5G NR bands. The publisher used Spirent Umetrix to push full buffer data traffic to our smartphone, which was locked to the anchor band and the 5G NR band. They captured scheduling information on the LTE anchor band and the 5G NR band. For DSS, they captured both LTE and 5G NR in the band.
Since they captured all scheduled resource elements (REs) for all attached mobile devices within the cell sector, the publisher could then precisely determine the percentage of REs used for user plane data traffic, control channel and broadcast channels, signaling, and those REs which went unused. As a frame of reference, in a 5 second capture they analyzed more than 129 million REs between LTE and 5G NR.
A Great DSS Tutorial
Thanks to real-world scheduling of LTE and data traffic, the publisher's able to offer a great tutorial on how DSS works, not only in theory but in practice. It is downright remarkable to see LTE signaling messages alongside 5G NR data traffic, not only in the same radio channel or slot/sub-frame, but sitting side-by-side in adjacent REs (1 RE is 15 kHz wide and lasts for only 0.000071 seconds).
It is pretty obvious in the data that vendors have been optimizing their LTE schedulers for more than the last decade and that they have only had commercial 5G NR solutions for approximately two years. This outcome is especially true for Nokia. With DSS (Ericsson) there are the inherent challenges of DSS which come into play. LTE schedulers (first place), dedicated 5G NR scheduler (second place) and DSS (third place) with double digit percentage point differences separating them.
This study is hopefully just the beginning. Other likely studies involve Open-RAN vendors versus 500 pound Gorillas, the inclusion of other vendors, and tracking the progress of all vendors in an unfiltered manner over time.
