I realize there is most likely an explanation that doesn’t require intelligent alien life, but that screams Dark Forest Theory.

We should broadcast the coordinates of a distant star to see what happens.

There are a lot of cool concepts in those books, but the sophon faster-than-light communication that props up a lot of the story was a bit too much for me.

The theory of quantum entanglement is sound though, and it took a while for a single sophon to arrive before the FTL communication. Layman here, but I thought it was relatively had science/speculative fiction.

Unfortunately the sound theory of quantum entanglement disallows FTL communication: https://en.wikipedia.org/wiki/No-communication_theorem

Which books, if I may ask?

The Three Body Problem and it's sequels by Liu Cixin. The series is called "Remembrance of Earth's Past".

Which space do you build the coordinates from? How will you encode them?

Give distances to pulsars with an arbitrary scale. The receiver can solve for the scale once they figure out which pulsars you are referring to. Identifying pulsars could be as easy as a pulse modulated with the frequency of the pulsar...

1) The one relative to the receiver of the coordinates

2) You start by explaining the encoding first, before sending coordinates, maybe by establishing X and Y axes as well as compass direction based on “landmarks” that should be visible from the receiver.

That’s the first thing that came to my mind at least.
