Query: Frame-Like Action and Unfolded Formulation for Massive Higher-Spin
  Fields   Unfolded equations of motion for symmetric massive bosonic fields of any spin
in Minkowski and (A)dS spaces are presented. Manifestly gauge invariant action
for a spin $s \ge 2$ massive field in any dimension is constructed in terms of
gauge invariant curvatures.
