I'm sorry I don't understand the question.
Either use inheritance or repeat the name.

template<class T>
struct A
{
      typedef T type;
};

template<class A>
struct B : A
{
};

or

template<class A>
struct B
{
     typedef typename A::type type;
};

you can do the same with non-type template parameters.
