The ab initio quasirelativistic approach was used to derive transition data for Pd-like tungsten W${}^{28+}$ ion. This approach was developed specifically for the calculation of spectral parameters for highly charged ions. The relativistic effects were taken into account in the Breit–Pauli approximation. The configuration interaction method was applied to include electron correlation effects. The ground configuration ${4\mathrm{p}}^6{4\mathrm{d}}^{10}$ and the lowest excited ${4\mathrm{p}}^6{4\mathrm{d}}^{9}4\mathrm{f}$ were considered. The calculations for W${}^{28+}$ were performed with different sets of interacting configurations in order to evaluate reliability and accuracy of produced results. Level energies, radiative lifetimes $\tau$, Landé $g$-factors were determined for the excited configuration ${4\mathrm{p}}^6{4\mathrm{d}}^{9}4\mathrm{f}$ of W${}^{28+}$ levels. The radiative transition wavelengths $\lambda$ and emission transition probabilities $A$ for the electric and magnetic transitions of various multipole order (up to E5 and M4) among the levels of these two configurations were produced. The uncertainties of computed spectroscopic parameters were evaluated.
