Narrative:

Approximately AB45 I contacted mia ground frequency 121.8, requested clearance to push back and taxi aircraft from old hangar to gate. Authority/authorized to proceed and hold short at the end runway 9L was received. I proceeded, following the instructions. I held short at end of runway 9L and contacted mia ground twice to let it know I was waiting for instructions to proceed. I understood mia ground gave me clearance to cross runway 9L at the end, so I proceeded to do so. After crossing runway 9L, I contacted mia ground to let it know runway 9L was cleared. The operator answered me that he never gave me clearance. Instructed me to continue to the gate and contact the tower by phone. I did it. I continued taxiway M till taxiway M8, stop at spot B. Ground support pulled the aircraft to the gate.
