Signals cannot be named inside of the Bus Creator block in Simulink. However, the Bus Creator block will use the names given to the signals going into it. To name these signals, double click the lines and a cursor should appear for you to type in signal names, which will be reflected in the Bus Creator and the Bus signal itself.
