  In this paper, a gauge invariant description of massive higher spin bosonic
and fermionic particles in frame-like Lagrangian and unfolded formalism in
(A)dS${}_4$ is built. A complete set of gauge invariant object is also
constructed and the Lagrangian is rewritten in terms of these objects. The
unitarity of the theories is studied alongside with the partially massless
limits. The calculations are carried out in the multispinor formalism, which
simplifies them and is particularly convenient for the supersymmetry studies.
