  The possible pairing symmetries for BiS$_{2}-$based superconductors is
investigated by using a minimal two-orbital model with onsite and
nearest-neighbor intraorbital attractions $V_{0}$ and $V_{1}$, respectively. By
using the mean-field approximation and solving the self-consistent equations,
the phase diagram of the pairing symmetry is obtained. It is shown that the
model allows three possible pairing symmetries, depending on the values of
$V_{0}$ and $V_{1}$: the isotopic $s-$wave pairing
[$\Delta_{\mathbf{k}}=\Delta_{s}$], the anisotropic $s-$wave pairing
[$\Delta_{\mathbf{k}}=\Delta_{s}+\frac{\Delta_{xs}}{2}(\cos k_{x}+\cos k_{y})$]
and the $d-$wave pairing [$\Delta_{\mathbf{k}}=\frac{\Delta_{d}}{2}(\cos
k_{x}-\cos k_{y})$]. Furthermore the density of states for these pairing
symmetries exhibit different behaviors which can be used to distinguish them.
