Resume of dual connectivity from secondary node with delta configuration

A method for wireless communication at a master node, comprising:

• communicating with a user equipment (UE) operating in a dual-connectivity mode in accordance with a first lower layer configuration;
• transmitting a release message prompting the UE to transition from a connected state to an inactive state;
• receiving a report of cell quality measurements performed by the UE in the inactive state, wherein the report is received as part of a procedure used by the UE to transition back to the connected state;
• and
• transmitting an indication of a second lower layer configuration for the UE to use for communicating in the dual-connectivity mode based at least in part on receiving the report, the second lower layer configuration being indicated as an offset of the first lower layer configuration.

An apparatus for wireless communication at a user equipment (UE), comprising:

• a processor,
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• communicate with a master node and a secondary node in a dual-connectivity mode using a first lower layer configuration;
• perform, after transitioning to an inactive state, cell quality measurements on signals received from the master node and the secondary node;
• determine that the cell quality measurements satisfy one or more thresholds;
• determine to transition from the inactive state to a connected state to resume communications in the dual-connectivity mode;
• report the cell quality measurements performed on the signals received from the master node and the secondary node;
• and
• receive an indication of a second lower layer configuration for communicating in the dual-connectivity mode based at least in part on the reporting, the second lower layer configuration being indicated as an offset of the first lower layer configuration.
