A comprehensive analysis of CMS searches for heavy vector boson resonances decaying into various final states is presented, utilizing the full Run 2 dataset at 13 TeV. The combination of multiple search channels yields the most stringent constraints to date on the BSM parameter space. The results set limits on the production and coupling strengths of heavy bosons within a simplified model framework. Driven by advancements in analysis techniques and the combination significant improvements over previous constraints are achieved.
