Abstract: Methods, systems, and devices for wireless communications are described. Generally, a UE in a connected state with a cell of a first radio access technology (RAT) type may trigger a UE initiated inter-RAT redirection procedure to a neighboring cell of a different, higher priority level, RAT type if the network does not configure the UE to perform connected measurements for candidate neighbor cells of the higher priority level RAT type. A UE may receive an indication of candidate neighbor cells of a higher priority level RAT type.

The UE may trigger an inter-RAT redirection procedure to one of the neighbor cells of the higher priority level RAT if the UE finds a suitable cell based on the UE initiated measurements.
