Group Signalling Aspects for NR-NR Dual Connectivity (NR-DC) and Reconfiguration

A method performed by a base station for handling group signalling of secondary cell, SCell, configuration information, the method comprising:

• sending (1110) configuration information for at least a first SCell to a wireless device, wherein the configuration information comprises values for one or more fields in a set of fields;
• and
• providing (1120) an indication relating to the configuration information to the wireless device, the indication indicating whether the configuration information is to be used to replace previously-stored values for the one or more fields.
