W skrócie:

W czasie Present Perfect Continuous operatorami są "have been", "has been", a czasownik występuje w formie Present Participle - czyli jest to czasownik z końcówką "ing"

Zdań w Present Perfect Continuous używamy aby powiedzieć o tym, co działo się ciągle przez jakiś czas do teraz. 

I have been waiting for you here for an hour. - Czekam na Ciebie tutaj od godziny.
