Enabled

Enables or disables the primary (PSS) and secondary (SSS) synchronization signals/ physical broadcast channel (SS/PBCH) in a radio frame. PBCH carries the Master Information block (that is, the minimum system information) such as SFN, subcarrier spacing( SIB1, msg 2,4, SI messages), CORESET for SIB1, cell barred, DMRS position, and intra frequency selection. PBCH is transmitted very frequently at TTI 80 ms, uses QPSK modulation and Polar channel coding for error protection.

Couplings

Coupled with Numerology Mode and Numerology Enable of resource grid and carrier numerology and Max RB.

When Numerology Mode is single mode, this setting’s value will be coupled to be same with carrier numerology.

When Numerology Mode is multiple mode, the value ranges of this setting are those Numerology Enable of resource grid being enabled except MU2Ncp|MU2Ecp.

For example if Numerology Enable of resource grid with numerology 0 and 1 are enabled, then this setting’s value range will be u = 0: 15 kHz | u = 1: 30 kHz.

When current value of this setting is not in the valid value ranges, this setting will be coupled to the valid value automatically.

When Numerology Mode is single mode and carrier numerology is set to MU2Ncp or MU2Ecp, error +690 "5GNR error; SS PBCH can’t be enabled because under single numerology mode with 60k subcarrier spacing, please turn it off." will be shown.

When Numerology Mode is single mode and Max RB is less than 20, error "SS PBCH can’t be enabled because under Max RB is too small, please turn it off." will be shown.

When Numerology Mode is multiple mode and in FR1, resource grid 0 and grid1 are in disabled states, error +690 "5GNR error; The Resource Grid used for SS/PBCH is not enabled."

When Numerology Mode is multiple mode and in FR2, resource grid 3 and grid 4 are in disabled states, error +690 "5GNR error; The Resource Grid used for SS/PBCH is not enabled."

When Numerology Mode is multiple mode and the grid size of resource grid with same numerology with SS/PBCH is less than 20, then error +690 "5GNR error; The Resource Grid used for SS PBCH is too small to include SS PBCH."

SS Block Pattern

Sets the Time Domain pattern of SSB Transmission as defined in 3GPP 38.213.

3GPP specifies a primary synchronization signal (PSS) and a secondary synchronization signal (SSS). They work in synchronization with the PBCH. PSS and SSS provide radio frame synchronization and detection of the physical layer cell ID and PBCH carriers the general system information.

The selected SS Block numerology determines the available SS Block pattern(s), depending on the subcarrier spacing

RB Offset by 15kHz SCS

Sets the SS Block RB offset for this SS/PBCH. Use the kSSB setting to adjust the SS Block's offset at the subcarrier level.

The default value is 253 RB (center of default FR1, 100 MHz Bandwidth with 30 kHz subcarrier spacing).

The range is based on the max RB and numerology of the carrier.

When the numerology of carrier is changed, RB Offset and k0 are automatically updated to ensure the SSB is in the middle of carrier for the new numerology.

kSSB by 15kHz SCS

Sets the subcarrier offset between the first subcarrier of SS/PBCH and the last subcarrier of RB Offset (15 kHz|60 kHz). The numerology used for this depends on the numerology of SS/PBCH. If SS/PBCH numerology is 15 kHz or 30 kHz, the unit of this kSSB is 15 kHz. If SS/PBCH numerology is 120 kHz or 240 kHz, the unit of kSSB is 60 kHz.

SSB location is not fixed in cell bandwidth like LTE, which had PBCH and PSS/SSS around the center frequency. The position of SSB in frequency domain is identified by a higher-layer parameter, offsetToPointA and by the higher-layer parameter, ssb-SubcarrierOffset. The quantity kSSB is the subcarrier offset from subcarrier 0 in SSB common resource block to subcarrier 0 of the SS/PBCH block. Where SSB common resource block is obtained from the higher-layer parameter offsetToPointA and the 4 least significant bits of kSSB are given by the higher-layer parameter SSB-SubcarrierOffset. If SSB-SubcarrierOffset is not provided, kSSB is derived from the frequency difference between the SS/PBCH block and Point A. SS block signals would apply default numerology defined per frequency band/range so that UE in initial access can assume single numerology for these signals. However, in case of NSA carrier access, NR supports the indication of SCS used for SS block transmission so that the mixed numerology between the data/control can be avoided.

If there is a frequency delta (difference) between the measurement center frequency and the carrier center, adjust the SS/PBCH RB Offset and kSSB accordingly to reflect this difference. It is best to match offsets; however, if you cannot achieve an exact match between the generated signal's center frequency offset and the offset created using the RB Offset and kSSB settings, you may still get good EVM results as long as the residual frequency offset is within the frequency lock range.

For SS/PBCH block in numerology 0 and 1, SSB common resource block is expressed in terms of 15 kHz subcarrier spacing.

For SS/PBCH block in numerology 3 and 4, SSB common resource block is expressed in terms of 60 kHz subcarrier spacing.

When the numerology of carrier is changed, RB Offset and k0 are automatically updated to ensure the SSB is in the middle of carrier for the new numerology.

Couplings

Coupled with Numerology Mode and Bandwidth.

  • When Numerology Mode is single mode, this setting is read only.

  • When Bandwidth is set to FR1 from FR2, this setting will be coupled to the SCS30K, and the valid values are SCS15K and SCS30K.

  • When Bandwidth is set to FR2 from FR1, this setting will be coupled to the SCS120K, and the valid values of this setting are SCS60K and SCS120K.

Preset

SCS30K

ssb-SubcarrierOffset

Specifies the Synchronization Signal Blocks (SSB)-Subcarrier Offset value in the Master Information Block (MIB) content.

SSB consists of both primary and secondary synchronization signals. There is one symbol used for PSS, 1 for SSS and 2 symbols for PBCH. One or more SS Blocks forms an SS Burst. One or more SS burst is called a SS Burst set where the transmission is periodic at 20 ms by default. It is confined within a 5 ms window.

This parameter corresponds to kSSB. When kSSB changes, it will be equal to kSSB, but you can manually modify it to a value larger than 23.

The 4 least significant bits of kSSB are in the MIB contents, and the most significant bit of kSSB is in the PBCH payload.

dmrs-TypeA-position

Sets the value of the Demodulation Reference Signal (dmrs)-TypeA-position in the MIB content.

DM-RS provides synchronization and uplink channel information. There is a separate DM-RS for PUSCH and PUCCH. It is sent in either 1 or 2 symbols in every time slot for PUSCH. For PBCH, PDCCH and PDSCH. DMRS for PBCH is spread over the same bandwidth as the PBCH (on the same symbols). PUSCH DMRS is the uplink user's shared channel DMRS and is transmitted in each resource block allocated to the user. PUSCH is transmitted during symbol 3 (normal CP) or symbol 2 (extended CP). The modulation type used is Zadoff-Chu, causing the constellation for DMRS to look like irregularly spaced points in a circle.

pdcch-ConfigSIB1 (RMSI-PDCCH-Config)

Set the value of pdcch-ConfigSIB1 (RMSI-PDCCH-Config) in MIB content, which is used to determine the location of Initial downlink BWP, see more information in section 13 of the 3GPP Std 38.213 section 4.1.

If the field ssb-SubcarrierOffset indicates that SIB1 is not present, the field pdcch-ConfigSIB1 indicates the frequency positions where the UE may find an SS/PBCH block with SIB1, or the frequency range where the network does not provide SS/PBCH block with SIB1.
