In Rel-15 upperLayerIndication is only used to indicate UE that the E-UTRAN cell is EN-DC capable. ( adica suporta 5G)

 

3GPP TS 36.331 V15.6.0 (2019-06)

Evolved Universal Terrestrial Radio Access (E-UTRA);
Radio Resource Control (RRC);
Protocol specification
(Release 15)
 

 SystemInformationBlockType2

The IE SystemInformationBlockType2 contains radio resource configuration information that is common for all UEs.

Orange Romania  NSG Screenshot:


  • Vodafone Romania,  HUA Radio, SIB2: upperLayerIndication-r15 : present on some cells; Screenshot below. (UE displays 5G when 5G carrier is added. Blind or measurement based addition. If blind then it then just adds the carrier, if measurement based then it sets up a B1 trigger for NR and if triggered then it adds the carriers)
