Minimization of drive test for multi radio access technology dual connectivity
Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently collecting and reporting minimization of drive test (MDT) measurements for one or more radio access technology (RAT) types and/or for multiple base stations in a dual connectivity deployment. In one example, a user equipment (UE) may receive an MDT measurement configuration indicating a first RAT type for collecting measurements and a second RAT type for reporting measurements. In this example, the UE may use the measurement configuration to collect MDT measurements for the first RAT type, and the UE may report the MDT measurements to a base station associated with the second RAT. Further techniques for efficiently collecting and reporting MDT measurements in a dual connectivity deployment are also described herein.
