There is also no equation, which could eventually be interpreted as delay calculation.

Delay for a signal from A->B in distance x would be:

Extremely simple, isn't it?

Extremely stupid insteed x=c*t is not generally true. x/c is
not at all the delay your asking for. (AB)/c is such a delay.

So the value 'x' is a coordinate in respect to system K  with distance |x| to system K's center.

Well, yes, this was a little bad, because I had to explain it in the first place, before I could use this setting.

 What you "explain" is, again, something you made up out of nothing.
 Systems K and k are even defined yet in paragraph 2.
 It makes basically no sense to put the center of K at A and the
center of k at B. K and k are in relative motion while clock-A
and clock-B are mutually at rest. So your "setting" is setting
v to 0.

What???
A coordinate system can actually be placed anywhere.
Here we have a point 'A' and an observer (also called 'A') and a coordinates system called 'K'.
The best and most natural setting would be, that you place the coordinate system with its center at 'A' and also the observer in K there.
Since the coordinate system k is equivalent in function and settings, we should place 'B' in the center of k.
This is simply the best way to place all the items mentioned into a useful order.
If you (or Einstein) like something else, this would be allowed, but you had to say so.
