Definition

The IE L1-MeasConfigNRDC is used to indicate or request a maximum value that can be used by the SN in NR-DC to configure L1 measurement related to LTM at the SCG. Each value is equal to or lower than the value of the corresponding field in the UE capability, as reported by the UE, unless specified otherwise. The value indicated by each field is applicable to all BCs within the field allowedBC-ListMRDC .
