  We discuss a linearization procedure of nonlinear supersymmetry (NLSUSY)
based on the closure of the commutator algebra for variations of functionals of
Nambu-Goldstone fermions and their derivative terms under NLSUSY
transformations in Volkov-Akulov NLSUSY theory. In the case of a set of bosonic
and fermionic functionals, which leads to (massless) vector linear
supermultiplets, we explicitly show that general linear SUSY transformations of
basic components defined from those functionals are uniquely determined by
examining the commutation relation in the NLSUSY theory.
