BWP: BandWidth Part:

contiguous subset of physical resource

blocks within the overall carrier bandwidth

of a certain frequency spectrum

Rohde & Schwarz

BANDWIDTH PARTS (BWP)

Motivation: Provide a flexible method to assign various numerologies to a device, thereby

adapting to different QoS requirements.

Nov 2019 5G MNT technology introduction22

Up to four BWPs in DL/UL per UE:

ı Single BWP at a given time

(active BWP)

ı No reception of PDSCH or

PDCCH outside DL BWP

ı No Transmission of PUSCH

or PUCCH outside UL BWP

ı BWPs can be switched by RRC

(slow), DCI (fast) or based on

timers

Rohde & Schwarz

SS/PBCH BLOCKS = SSB

► Time domain:

SSB consists of 4 OFDM symbols, where

PSS, SSS and PBCH with associated

DM-RS occupy different symbols

► Frequency domain:

SSB consists of 240 contiguous

subcarriers

► Like in LTE the Cell ID can be determined

from the used PSS/SSS sequences

Synchronization Signal Block = SSB

PSS: Primary Synchronization Signal SSS: Secondary Synchronization Signal

PBCH: Physical Broadcast Channel DM-RS: DeModulation Reference Signal

SSB AND DIFFERENT BEAMS – „BEAMFORMING“

► Demodulation of the PBCH determines the SSB index and

distinguishes between the periodically broadcasted SSBs

► Each SSB uses different DM-RS embedded in the PBCH (FR1: PBCH in 3 OFDM symbols,

in each symbol PBCH DMRS sequence is initialized differently 23 = 8 options)

► Example: Case A with subcarrier spacing of 15 kHz and 8 SSB indices

Rohde & Schwarz

SSB – IN SINGLE BEAM OR MULTI BEAM CONFIGURATION

► SSB index is used to separate SSB

transmission on different beams

(encoded in the MIB)

► Mapping of antenna ports and

physical beams to the SSB index can

differ between infrastructure suppliers

► SS Bursts can also be repeated

(periodicity is given in MIB)

The decibel (symbol: dB) is a unit of measurement used to express the ratio of one

value of a power quantity to another on a logarithmic scale. It is called the power level.

BANDWIDTH OF NETWORK SCANNER (THE 100 MHz QUESTION)

Nov 2019 5G MNT technology introduction37

20 MHz – the most efficient choice for RF frontend

ı 5G NR offers higher bandwidths, but: ı All SSB below 6 GHz fit into 20 MHz bandwidth

ı There is no other always-on signal in 5G NR downlink than the SSB

ı Spectrum measurements over the whole frequency range (spectrum scan,

Automatic Channel Detection) are done with 20 MHz frontend since years

ı SSB measurement in mmWave frequencies (120 and 240 kHz subcarrier spacing)

with one 20 MHz scanner frontend using fast frequency hopping

ı Better noise figure than 100 MHz frontend

ı Better receiver sensitivity

ı Best approach for multi-technology measurements (2G, 3G, 4G, 5G)

All important 5G NR network measurements are done using a 20 MHz scanner frontend

Rohde & Schwarz

5GNR SSB

HOW TO FIND THE SSB EASILY? 5G NR SCANNER – AUTOMATIC CHANNEL DETECTION (ACD)Often the SSB frequency is

not exactly known before

executing 5G NR

measurements.

The 5G NR ACD automatically finds the SSB by detecting:

ı SS-Ref frequency of 5G NR cell-defining SSBs following GSCN raster (3GPP compliant)

ı Cell-defining SSBs which are apart from the GSCN channel raster

ı The transmission case (number of SSBs) is determined by the SS-Ref

QUESTIONS: CAN WE MAP THE SSB INDICES ON BEAMS? HOW DOES BEAMFORMING WORK?

► First approach:

Assumption: Each SSB index can be

mapped to a certain beam

► How to analyze that?

Use the ROMES4 map feature and

display the strongest SSB index on a map
