  We consider the $sl(2)$ quantized Knizhnik-Zamolodchikov equation (qKZ),
defined in terms of rational R-matrices. The properties of the equation change
when the step of the equation takes a resonance value. In this case the
discrete connection defined by the qKZ equation has a invariant subbundle which
we call the subbundle of quantized conformal blocks. Solutions of the qKZ
equation were constructed in [TV1], [MV1] in terms of multidimensional
hypergeometric integrals. In this paper we show that for a resonance step all
hypergeometric solutions take values in the subbundle of quantized conformal
blocks, moreover the values span the subbundle of quantized conformal blocks
under certain conditions. We describe the space of hypergeometric solutions in
terms of the quantum group $U_qsl(2)$.
