Why and how can TCAS and SSR transponder work at the received frequency of each other?

How to calculate the Traffic Advisory (TA) range limit above the maximum altitude limit (take 16000 ft) of an aircraft?

It does not factor in. Why would it? The lower aircraft does not know the higher aircraft's intentions, and an aircraft passing 200 feet above is definitely a threat. The higher aircraft does not know ...
