Description
Block 5G Waveform Generator generates a 5G downlink signal of the NR main frequency band (NR – New Radio, radio access technology for 5G networks). The unit allows you to configure and generate a synchronization signal packet SS, CORESET 0, PDCCH or PUCCH, PDSCH or PUSCH and the associated DM-RS and PT-RS, as well as CSI-RS or SRS.
The minimum bandwidth of the channel for the NR range is set using the parameter Minimum channel bandwidth for the NRb (MHz) to determine the frequency resources of CORESET 0. For more information about the channel bandwidth for each NR band, see [1] (Table 5.3.5-1).
The frequency range used for the 5G standard is specified in the documentation. The standard designations of the frequency ranges and their corresponding frequencies are given in the table:
| Frequency range designation | Frequency range |
|---|---|
Frequency Range 1 (FR1) |
|
Frequency Range 2 (FR2) |
|
Frequency range Block Pattern For the SS packet, it is used to set the distance between the SS/PBCH subcarriers. Custom hardware searches for SS block patterns based on the NR operating range. For more information about the frequency ranges, see [2] (Tables 5.4.3.3-1 and 5.4.3.3-2).
Configuring the block includes setting the following parameters:
-
Setting up the cell ID: parameter Physical layer cell identity.
-
Configuring the SS package.
-
Setting the frequency range Block Pattern: FR1:
Case A,Case B,Case C, FR2:Case D,Case E. -
Setting the number of transmitted information blocks Bitmap of SS blocks transmitted:
4,8,64. -
Setting the distance between subcarriers Subcarrier spacing (kHz):
15kHz or30kHz for FR1,60kHz or120kHz for FR2. -
Setting the minimum channel bandwidth for the NR range Minimum channel bandwidth for the NRb (MHz)
5MHz,10MHz,40MHz. -
Setting the gain SNR boost (dB) when forming a beam by increasing the power (and therefore the signal-to-noise ratio) of a single SSB, PDCCH and PDSCH.
-
-
Adding white Gaussian noise SNR for AWGN (dB) to the signal. Note that the signal-to-noise ratio applies only to the amplified SSB.
The result of the block operation is a 5G NR signal in the time domain, returned as a complex matrix. The number of columns of the matrix corresponds to the number of transmitting antennas.
