How do I go about deriving the thermal conductivity of graphene (specifically, in the low temperature limit) when I'm given the phonon dispersion relation?

I haven't been able to find anything explaining how the dispersion relation relates to the thermal conductivity in materials. (this is for a solid state physics course)
