what is the meaning of the sentence "papers are already been communicated"
It is grammatically incorrect.
The sentence should read: "papers have already been communicated".
This is a standard passive form using the present perfect and meaning that someone has communicated the papers.
I'm not sure that "papers" can actually be "communicated" though.
It may be some form of legal talk meaning that the papers have been passed from one office to another or something similar.
