Figure 71. Time-Frequency Resource Block Allocations of 5GNR TM2 signal under test
Frequency Spectrum of the Signal
The signal has most of the synchronization data and reference symbols concentrated in 2 subcarriers at the edges of the
spectrum, and one sub-carrier in the middle of the 100Mhz bandwidth. The sub-carrier spacing is 30KHz.

Time Domain Analysis of the Signal
Shown below is a time domain view of the signal zoomed in for ~860us. In Figure 10, the time has been further subdivided into 4
timing intervals(T1, T2, T3, T4) during which different resource blocks are active, and therefore consists of different frequency
contents. The symbol period is ~33.34us for normal CP.
