You cannot, as written. If you want a helper function in a macro
definition, you put the function inside the macro definition:

(module z mzscheme
  (define-syntax (g stx)
    (let ()
      (define (f x) x)
        (syntax-case stx ()
          ((_ e)
           (datum->syntax-object stx (f (syntax-object->datum #'e)))))))

You probably will want to use define-syntax-set for a more general
