3GPP release 15 specifies the initial 5G standardization framework of the radio access network called 5G New Radio (5G NR). The standard contains a high degree of flexibility in radio parameters, which complicates network measurements. However, Rohde & Schwarz has already conducted measurements in pre-commercial 5G NR trial networks with its commercially available 5G NR network measurement solution. We gained interesting insights into the new technology’s performance, capabilities and frequency bands.

5G NR UE based network measurements

Another important part of 5G NR network testing is using 5G NR devices such as evaluation boards, USB dongles, pre-commercial and commercial smartphones as they become available. This will provide insights into network quality regarding quality of experience (QoE) of applications, the interaction of devices with the real 5G NR networks and the device performance itself.

Such 5G NR UE based measurements include NR serving cell information such as NR DL ARFCN, PCI and SSB index, layer 1 RSRP / RSRQ, layer 2 PDSCH, PDCP, PUSCH information, LTE-NR EN-DC L3 signaling and application layer information (see Figure 9).

The R&S ROMES4 software suite for in-field real-time analysis supports the connection of the first-on-the-market Qualcomm X50 based UEs for 5G NR measurements. Rohde & Schwarz has demonstrated this capability of its network measurement solutions during the introduction of previous mobile communications technologies.
