Glossary Item Box

Gets or sets the source of synchronization for this carrier if this carrier is downlink carrier.

Syntax

Visual Basic (Declaration) 
Public Overridable Property DownlinkSynchronizationSource As SynchronizationSource
C# 
public virtual SynchronizationSource DownlinkSynchronizationSource {get; set;}
C++/CLI 
public:
virtual property SynchronizationSource DownlinkSynchronizationSource {
   SynchronizationSource get();
   void set (    SynchronizationSource value);
}

Property Value

The default value is SynchronizationSource.Auto

Remarks

This parameter is only used when the LinkDirection of this carrier is LinkDirection.Downlink. The first step of VSA 5G NR measurement is to use some known signal to identify the frame boundary, at the same time the coarse frequency offset is estimated. This process is called initial synchronization. For Downlink carrier, SSB or PDSCH-DMRS or PDCCH-DMRS can be used as the synchronization source. When SynchronizationSource.Auto is used, VSA automatically decides which source is used, the priority order is SSB first, then PDSCH-DMRS, and then PDCCH-DMRS, and then CSI-RS. If there are multiple instances of the selected source type, the first one has higher priority, then the second and etc.. If SynchronizationSource.Auto is used, DownlinkSynchronizationSourceIndex will not be used. If other SynchronizationSource is used, this value along with DownlinkSynchronizationSourceIndex decides which signal is used as synchronization source. VSA will check whether the selected source is enabled in the signal configuration. If the selected source is not enabled, SynchronizationSource.Auto will be used.
