28 Claims

1. A method for wireless communications at a user equipment (UE), comprising:

identifying that the UE is operating in a dual connectivity configuration with a master node and a secondary node, wherein the UE is in an inactive communications state with the secondary node;

receiving, with a release message instructing the UE to enter the inactive communications state, a measurement configuration for a secondary cell group comprising the secondary node of the dual connectivity configuration;

determining that secondary node communications are to resume;

determining whether a previously stored lower-layer secondary cell group configuration can be used for the resumption of secondary node communications;

and

transmitting an indication to the master node indicating whether the previously stored lower-layer secondary cell group configuration can be used to resume the secondary node communications.
