Glossary Item Box

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

Syntax

Visual Basic (Declaration) 
Public Overridable Property UplinkSynchronizationSource As SynchronizationSource
C# 
public virtual SynchronizationSource UplinkSynchronizationSource {get; set;}
C++/CLI 
public:
virtual property SynchronizationSource UplinkSynchronizationSource {
   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.Uplink. 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 Uplink carrier, PUSCH-DMRS or PUCCH-DMRS or SRS or PRACH can be used as the synchronization source. When SynchronizationSource.Auto is used, VSA automatically decides which source is used. When PRACH is enabled, always use PRACH as the sync source. When PRACH is not enabled, the priority order is PUSCH-DMRS first, then PUCCH-DMRS, and then SRS. 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, UplinkSynchronizationSourceIndex will not be used. If other SynchronizationSource is used, this value along with UplinkSynchronizationSourceIndex 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.
