9 In cooperation with Rohde & Schwarz (hereinafter referred to as R&S), DingLi Corp Ltd. has developed its first 5G NR test and measurement solution with Pilot Pioneer using the R&S TSME-6 scanner. The solution has been thoroughly tested in various 5G NR system trials with some of the leading mobile network operators in China, and recognized for its measurement reliability and validity.
Solution Overview
Pilot Pioneer with R&S TSME-6 supports 5G NR pilot and spectrum scan, data decoding and coverage statistics. These scan measurements are essential for the initial 5G NR coverage verification, and detection of external interference sources for spectrum clearance. Some of the key features and metrics include:
Supports all 3GPP R15 Sub-6 GHz frequency bands, including 2.6GHz, 3.5GHz, 4.9GHz, etc.
Beam ID, SS-RSRP and SS-SINR measurements, etc.
MIB message decoding, ACD (Automatic Channel Detection) and Multi-Path measurements.
Statistics presentation and detailed analysis of measurement logfiles.
Test and Measurement
Spectrum Scan
Pilot Pioneer is able to detect and display the peak signal strengths of all Sub-6 GHz 5G frequency, and test each frequency and signal strength accurately. Spectrum scan is applicable for the following scenarios in the initial stage of network deployment:
√Identify the spectrum availability.
√Verify the expectedchannel bandwidth of the 5G carrier.
√External interference detection.
√Verify signal coverage for UE accessibility.
Effect of Beamforming
Pilot Pioneer accurately measures the 5G NR synchronization signal block (SSB) of each Beam, and display the respective SSB Index, SS-RSRP, SS-RSRQ and SS-CINR, etc. The main application scenarios of SSB measurement are as follows:
√Coverage test
√Beamforming test
Statistics and Analysis
Cell Coverage Stability
Pilot Pioneer Expert generate statistics for dedicated signal stability analysis. This is achieved through the cell filter function and stationary scan measurement of Synchronization Signal Blocks (SBB) beams with other key metrics (i.e. SS-RSRP, PCI).
Statistics for Serving Cells
The strongest SS-RSRP and the cell information for each serving cell would be summarized in Pilot Pioneer Expert to display the overall network coverage.
