How to use rel="alternate" and rel="canonical" together?

Question

Search Engine Optimization

There is a multilingual site. Relevant pages are linked by rel="alternate" tags. On the site there are pages with parameters that, in fact, are duplicates, i.e. for them, you need to set rel="canonical" to the same page, only without parameters (to avoid indexing duplicates like /page1.html and /page1.html?a=1). How to do it right? So far, such a scheme is on my mind

. pages that are canonical in the context of their language, we display with rel="alternate", if suddenly the page has parameters (which do not change its content), then we put rel="canonical" on it, indicating the same page in it , but without parameters.
Is such a scheme appropriate? Will the sickles understand?
