The invention is just the claims of a particular patent. The patent description must include enough information so the invention as recited in the claims could be replicated. Patent descriptions do not have to disclose details about the supporting/surrounding components of the whole system or platform. E.g., a patent claiming a method for selecting 5G channels does not need to describe how to build out a 5G network.
