1. At least one non-transitory machine-readable medium comprising a plurality of instructions that, in response to being executed by processing circuitry of a macro cell evolved node B (eNB), cause the macro cell eNB to:

  • gather information associated with one or more small cell eNBs, each of the one or more small cell eNBs to comprise a candidate for serving as a secondary cell for user equipment (UE) that also has the macro cell eNB serving as a primary cell, the gathered information associated with a first small cell eNB from among the one or more small cell eNBs, the gathered information to include a number of times a request to add the first small cell eNB as a candidate for serving as a secondary cell for the UE but the UE fails to establish a connection with the first small cell eNB; and

    send the gathered information in a minimization of drive tests (MDT) report to a management entity for an evolved packet core (EPC).
