5.3.5.13  Conditional Reconfiguration |R16|  p. 116

5.3.5.13.1  General  p. 116
The network configures the UE with one or more candidate target SpCells in the conditional reconfiguration. The UE evaluates the condition of each configured candidate target SpCell. The UE applies the conditional reconfiguration associated with one of the target SpCells which fulfils associated execution condition. The network provides the configuration parameters for the target SpCell in the ConditionalReconfiguration IE.
In NR-DC, the UE may receive two independent conditionalReconfiguration:
  • a conditionalReconfiguration associated with MCG, that is included in the RRCReconfiguration message received via SRB1; and
  • a conditionalReconfiguration, associated with SCG, that is included in the RRCReconfiguration message received via SRB3, or, alternatively, included within a RRCReconfiguration message embedded in a RRCReconfiguration message received via SRB1.
In this case:
  • the UE maintains two independent VarConditionalReconfig, one associated with each conditionalReconfiguration;
  • the UE independently performs all the procedures in clause 5.3.5.13 for each conditionalReconfiguration and the associated VarConditionalReconfig, unless explicitly stated otherwise;
  • the UE performs the procedures in clause 5.5 for the VarConditionalReconfig associated with the same cell group like the measConfig.
In EN-DC, the VarConditionalReconfig is associated with the SCG.
In NE-DC and when no SCG is configured, the VarConditionalReconfig is associated with the MCG.
The UE performs the following actions based on a received ConditionalReconfiguration IE:
1 >
if the ConditionalReconfiguration contains the condReconfigToRemoveList:
2 >
perform conditional reconfiguration removal procedure as specified in clause 5.3.5.13.2;
1 >
if the ConditionalReconfiguration contains the condReconfigToAddModList:
