It goes the other way around.

First you make the tech (and the patents associated with it) and then push it through the standards body to make it part of a standard. That is the point when it becomes a standard essential patent.

And usually the standards body require FRAND terms from the IPR 'donators' - they commit to license the tech using fair, reasonable and nondiscriminatory terms. They shouldn't deny a license or charge too much, with the idea being that they'll gain more from having interoperable products rather than maximise licensing royalties.
