Can a cellular automata structure simulates another cellular automata structure?
Any cellular automata that could be classified as a universal Turing machine would be able to do this. The Game of Life is one such cellular automata. Here is it (rather pointlessly) simulating itself on a larger scale. Here is a Turing machine implemented in it. This 'category' that you want is probably "cellular automata that qualify as universal Turing machines".
I suspect this question will be of interest to you.
