Abstract:
Generally, the described techniques provide for efficiently identifying a lower layer configuration for communicating in a dual connectivity mode after transitioning from an inactive state to a connected state. To efficiently identify the lower layer configuration, a UE operating in a dual connectivity mode may perform measurements on signals received from a master node, a secondary node, and other nearby nodes in an inactive state. Once the UE decides to transition back to a connected state, the UE may report the measurements and restore an original lower layer configuration used to communicate in a dual connectivity mode. The UE may then receive an indication of an updated lower layer configuration as an offset of the original lower layer configuration, where the updated lower layer configuration may be based on the reported measurements.
