Morphology
The meaning of 'reference frame' is directly compositional: it denotes a 'frame' (system or structure) used for 'reference' (to locate or compare positions). This noun-noun combination follows a common productive pattern and has close equivalents in many languages, so a B1 learner who knows both constituents can infer the intended technical sense.
Etymology
Reference frame may come from the image of a picture frame or a map reference grid that gives fixed points to measure from. So in science it means the system you use to tell 'where something is' and 'how it moves'.
