We give the definition of a bundle over a simplicial set in a similar way to that in general bundle theory. We define certain transition functions, called compatible transition functions, for the given bundle, as well as so-called admissible trivializations. Conversely, we give the description of an associated bundle over the realization of the simplicial set and trivializations for a given set of transition functions.
