the term "framework" describes theoretical or conceptual respectively framework conditions; it's a general description. The framework consists of theories, models, concepts and methods. In the beginning of a study, you have to develop the theoretical framework, e.g., you have to decide, which theories, models, concepts or methods are used by you (and you have to explain your decisions); also you have to explain your assumptions / preconceptions and your values. When creating your framework, you build up the necessary structure for your study (respectively research). I assume, the "theoretical or conceptual framework" is comparable with the "theoretical or conceptual background".
Try the following examples:

In my opinion, your question belongs to the field "philosophy of science", but I can not guarantee, whether you find the term there, because the term "framework" was originally used in the IT sector.
