The main idea of WENO schemes is a non-linear-weighted combination of several local reconstructions based on different stencils and the usage of it as a nal WENO as you can find in the wikipedia link. The problem stands for determining q (wavenumber), (frequency), so as for the system of the first equation to has nontrivial solution. Since the WENO scheme uses all the candidate stencils, a clever choice of weights [5] results in a WENO scheme which is of order 2r1 in smooth regions [8].
