Estimates of the generalized Stokes resolvent system, i.e. with prescribed divergence, in an infinite cylinder ${\mit\Omega}={\mit\Sigma}\times\mathbb R$ with ${\mit\Sigma}\subset \mathbb R^{n-1}$, a bounded domain of class $C^{1,1}$, are obtained in the space $L^q(\mathbb R;L^2({\mit\Sigma}))$, $q\in (1,\infty)$. As a preparation, spectral decompositions of vector-valued homogeneous Sobolev spaces are studied. The main theorem is proved using the techniques of Schauder decompositions, operator-valued multiplier functions and $R$-boundedness of operator families.
