Narrative:
Controller assigned heading of 010 degrees followed by turn right to 110 degrees descend to 10000 ft. This clearance was read back. Out of 10600 ft and descending, controller said 'you were only cleared to 11000 ft, climb back to 11000 ft.' we reached 10500 ft and then climbed back to 11000 ft. As far as I know there was no traffic conflict.
